Do-it-yourself automation for sliding gates. Automation for sliding gates. Assembly of the electrical circuit. Installation of safety photocells

The scheme for connecting automatic gates begins with the following steps:

1. Preparation of pillars for support.
2. Foundation preparation for automatic gates.
3. Carrying out wiring for automation.
4. Gate manufacturing.
5. Implementation of the installation.

The primary task is a reliable support

The first thing to do is to correctly install the pillars under the support, where later you will need to attach automatic gates. The material for the pillars can serve as a brick, concrete, channel bar or oak timber. It is recommended to concrete the column (in depth) from 1 meter, then all the columns are installed at the same level and filled with mortar. The curing time for concrete varies within seven days.

Important! Using pillars made of concrete or brick, provide for the placement of metal mortgages, three on each of them, equally spaced from the edge 10 centimeters from the side of the opening.

We prepare the foundation

To pour the foundation under the base of the gate, we use a channel, the width of which should be 20 centimeters, and reinforcement with a cross section of 12-16 millimeters. We cut the reinforcement up to 1 or 1.2 meters long, then weld both sides to the channel shelves.

Our next action is to dig a hole, which in its length will be 50 percent of the width of the sliding gate opening. The dimensions of the pit itself should not exceed:

• width - 40 centimeters;
• depth - up to 1.5 meters.

The channel should be installed with shelves downwards, and then we pour concrete into the pit. Having done everything as it should, we get the foundation for automatic (sliding gates).

Attention! The term for standing the foundation according to all norms and rules is 28 calendar days.

No automation anywhere

The electrical circuit of automatic gates depends on their type. So, today, there are three main types of automatic (retractable) gates, the connection diagrams of which are shown in the figures below.

Important! To avoid damage to the transformer, motor or control board and ensure stable operation of automatic gates, install voltage stabilizers. Thus, the price for a possible repair will be significantly reduced.

Do-it-yourself automatic gates, manufacturing scheme

The very first thing to decide is the type of material that we will use. To make a gate frame, you need a profile pipe. So, armed with a grinder, we remove the scale from the pipes.

Attention! When working with a grinder, do not forget about the use of special glasses to protect your eyes.

Having finished, we begin the process of welding the frame of our gates. In this case, a drawing diagram of an automatic gate or, as it is also called, a diagram of an automatic garage door, will help us. As an example, the figure below.

Having formed the outer frame, we weld the inner frame inside, which will give the structure hardness and serve for future fastening of wood, metal, corrugated board ...

For the frame placed inside, pipes 20 * 30, 20 * 40 millimeters are ideal. We weld them with tacks of two centimeters through a gap of 20 or 30 centimeters. A guide is welded at the bottom. We attach the guide and pipes in a checkerboard pattern.

We clean the welds and re-apply the anti-corrosion primer to the areas that were damaged. We are waiting for the soil to dry, and proceed to painting the gate.

Important! The paint should be applied in two layers.

After completing the painting work, we sew the canvas with self-tapping screws or rivets, attaching it to the pipe that is inside.

What? Where? How? Or do-it-yourself gate installation

After the foundation has stood, we proceed to the installation work. In order to avoid any difficulties during the process, you can ask for advice from experts or find information on the Internet simply by entering automatic gates, installation diagram or automatic gates, installation diagram in a search engine.

The procedure itself is quite simple, and consists in welding the hinges to the supporting bases and sashes.

When installing, do not forget to leave a gap between the wings and a gap in the middle of the ground and the canvas, which can later be hidden by a speed bump. The bolts that will fix the sashes should be welded to the inner frame.

As an example, we took the Miller Technics 1000 model, which can be installed on almost any gate - it will “pull” a leaf up to 10 m long and weighing up to 1000 kg.

Minimum equipment for obtaining a workable automatic system

You can save yourself from opening the gate manually with just 3 mandatory components. These will be: Control device Gear rack

Technical parameters of the Miller Technics 1000 model

Drive installation

Prepare the stand for the drive. It can be made from a pair of sections of pipes of rectangular or square section 30 cm long. Enough elements with dimensions of 40 * 40 mm or 40 * 60 mm.

These pipes are placed between the roller carriages on the embedded channel. It is too early to weld them - you just need to lay them in the planned place.

From above, also while without fastening, install the mounting base from the kit.

The drive is placed on the base. At this stage, you can do without screwing.

“Bonks” (fasteners) are screwed onto the segments of the gear rack, with a thickening outward and with a shift to the smooth upper edge (the holes are oval, therefore such a shift is possible).

The toothed rack is mounted on the outer gear of the drive in such a way that it passes in the middle of the element. The entire structure (the drive on the base and stand together with the gear rack) is moved to the sash.

"Bonks" should be in contact with the bottom tube of the goal frame.

Attention!"Bonks" are not welded to the guide profile, as the rail may be deformed.

If the “bonks” are above or below the frame pipe, then the support pipes should be replaced with elements of a suitable section.

When the dimensions of the stand are optimally selected, allowing the “bonks” to be located strictly against the frame pipe, the selected pipes are welded to the channel, and the mounting base to them. After that, the drive is screwed with bolts from the fastener kit.

Rack mount

The drive is first unlocked with a special key, and the gate is completely closed.

The toothed rack is supplied in 1 meter lengths. Attach them in sequence.

The first element is installed on the drive gear in such a way that a length of 30-50 cm protrudes towards the “tail” of the gate.

"Bonks" are welded to the lower tube of the frame. The final scalding will be carried out only after checking the ideal position of the toothed rack along the entire length. This approach makes it easy to eliminate errors during the installation process - it is enough to cut off such a tack with a grinder and adjust the position of the element.

After fixing the first element, the gate opens slightly by a meter.

The second segment is installed on the gear, and the junction with the already fixed part from below is supported by an inverted free rail. This allows you to get a "perfect tooth" without height differences at the junction of the pieces.

Deviation from this rule can lead to the fact that at the joints the outer gear will receive strong blows that are dangerous for it and the entire gearbox as a whole.

Only after obtaining the “correct tooth” can the “bonks” of the new element be welded to the frame.

Similarly to the second, all subsequent pieces of the gear rack are installed.

After mounting the last piece, it is necessary to provide a gap of approximately 1 mm along the entire length between the rack and the drive gear.

Due to the elongated holes for fastening the “bonks”, you can move the rail a little up. Adjustment is carried out manually by touch and does not present any particular difficulties.

With the gear motor unlocked, the outer gear should be taken from below and tried to move. If there is no movement or it is very difficult, then the rack should be raised higher.

The gap between the teeth of the pinion and rack must be the same throughout the entire length of the gate.

Describing adjustment in words is more difficult than the process turns out to be in practice. When you follow the steps described, you can make sure that everything is quite simple.

After setting each segment to the optimal position, it is required to securely fix it with mounting bolts.

After setting a gap of 1 mm along the entire length of the toothed rack, the ease of movement of the gate is tested (manually so far). If there are no comments, then the “bonks” are finally scalded with continuous seams. Welding areas are cleaned, primed and painted.

Electrical connections

A typical circuit involves the connection of the drive itself and important additional devices, namely photocells and a signal lamp. In practice, accessories are not always installed - the system can work without them, but with a reduced level of security. If the installation of barrier and lamp sensors is not provided, then the wiring for them will not be required.

Cabling

The wiring is usually hidden even before the paving is laid. Trenches are dug with a depth of at least 70 cm, along the bottom of which wires with external protection are laid. At the same time, it is recommended to take a plastic water pipe under the passage as a sleeve, the diameter of which can be 15-20 mm. Corrugated pipes are enough in the ground outside the passage.

Initially, a three-core cable with a cross section of 1.5 sq. mm is connected from the power supply (voltage 220 V) to the control board (located inside the drive). The remaining cables (2- and 4-core, 0.5 sq. mm each) are routed from the board to the accessories according to the diagram.

Connecting the control board to power

The cable from the power source (alternating current, voltage 220V) is connected to the drive and connected to the contacts of the control board marked "L" and "N".

Remote control coding

To make further adjustments to the automatic system, it will be necessary to program the remote control in order to be able to give commands to the drive.

There is a special “Learn” button on the control board that you need to press and release.

This action causes the red LED next to the button to light up.

This process is accompanied by an LED signal: it should blink twice and go out. This will confirm the entry of the remote control.

Positioning of magnetic limit switches

Magnetic limit switches are designed to timely stop the drive at the end of the maneuver. A pair of magnet brackets are mounted on the rack in such a way as to approach the sensor inside the actuator at the moment of full opening and closing.

Operating principle: the approach of the bracket to the reed switch leads to the opening of the relay under the influence of a magnetic field. This serves as a signal to stop the engine.

The magnets have different polarities so that the system “understands” the position of the sash (open or closed). When attaching the elements to the rack, make sure that they are correctly positioned. If you confuse the left with the right, the gate will not stop automatically.

For correct installation, the magnets are first placed on the gear rack at a distance of 10-20 cm from the drive housing with the gate half-open.

Having given a command from the remote control to move the gate, they observe the behavior of the automation at the moment the magnet approaches. If the motor stops, the polarity is correct. If the leaf "slips" further, then the gate is stopped by the remote control, and the magnets are reversed.

After making sure that the magnets are located on the correct sides, determine the exact location of their placement on the gear rack closer to its edges.

The magnet is considered to be correctly installed if the last couple of centimeters of the gate rolls smoothly by inertia, without moving further than it should. In no case should the sash hit the catcher when closing, on the contrary, a small gap should remain between their walls.

Performing a number of additional settings will allow you to activate the useful functionality of the control unit. Gate control will be more comfortable. To increase the safety of operation of automation, it is worth connecting peripheral devices.

Setting the operating time of automation

By default, the drive run time is set to 30 seconds. The factory settings can be changed to individual ones.

Usually, the engine is stopped by a signal from magnetic switches. But if one of them is damaged or the sash rests against something, then just the timed shutdown function will save the engine from burnout.

To set a specific operating time, the sash is completely closed, after which the “Test” button is pressed and held for 3 seconds.

The gate will automatically go through a full cycle of magnetic limit switches (open and close). After stopping, the operating time of the drive will be automatically fixed in the memory of the control board.

Obstacle Sensitivity Adjustment

There is a function that allows you to set the maximum allowable force. Exceeding this threshold leads to automatic shutdown of the engine. For example, if the leaf rests against an obstacle, then the load increases, which requires an adequate response to the situation - stopping the gate.

The required force can be set using the FORCE trimmer by rotating it in one direction or another.

Installation and connection of photocells

Basically, photocells are installed on support poles.

Alternatively, they can be attached to the flashings. The recommended height is 50-60 cm above the ground, so that they do not overlap with snowdrifts, but “notice” the hood of a car and pedestrians.

Paired sensors are placed opposite each other. At the same time, there should be no obstacles between them that prevent the infrared beam from going from the transmitter to the receiver. It is this beam that scans the passage, and its break gives a signal about the presence of an obstacle in the path of the sash.

Connecting security sensors.

First, connect the photocell that is located closer to the control unit:

Contacts "+" and "-" of the photocell are connected to the power supply of 15 V of the control board;

Contact "COM" of the photocell is connected to the contact "GND" of the board;

The "NC" contact of the sensor is connected to the "INFRO" of the board.

For the far photocell, it is only necessary to supply power, i.e. connect its "+" and "-" to the 15 V power supply of the board.

The factory-installed "INFRO-GND" jumper on the board must be removed, while the "STOP-GND" jumper remains in place.

After installing and connecting the photocells, it is necessary to check their effectiveness. When the beam breaks when the sash closes, the automation must reverse the movement, i.e. the gate should start opening. If the sash opens, then the beam break is either ignored or leads to a stop - there is no danger of the sash being hit, no reversal is needed.

If there is no reaction to a beam break when the leaf is closed, and the gate continues to move as if nothing had happened, then two pairs of contacts should be swapped:

Photocells are connected only after installation, connection and operation of the main equipment.

Mounting and connection of signal lamp

To install the lamp, a place is selected so that it can be seen from either side of the gate.

Signal lamp connection

The cables coming from the lamp are connected to the “Light” terminals of the control board.

You will learn about assembling an electrical control circuit with your own hands. We will tell you how to connect different types of motors and assemble starting equipment, as well as reveal the secrets of soft start and stop of automatic sliding gates.

Depending on the selected motor type, you can use different connection methods. Not only the electrical connection diagram will differ, but also the permissible current parameters.

Attention! When working with the electrical part, do not forget about the precautions: weld a bolt to the stationary frame, which will be used to connect to the ground loop.

Motor connection

A three-phase motor for a rated voltage of 380/220 V must have a star connection when connected to a three-phase power supply. You can change the direction of rotation by swapping the connection of any two of the three phases.

If you are trying to connect a three-phase motor to a single-phase network, give preference to the capacitive method. In this case, use a starting capacitor with a deliberately overestimated capacity (2-3 times) and add a pair of compensating capacitors for the two remaining windings to the working assembly, or provide for switching off the starting capacitor using a time relay. The capacity of the working capacitor is selected at the rate of 70-80 microfarads per 1 kW of power, and the nominal value is 450 V.

A single-phase capacitor motor has four wires in the assembly, that is, two ends of the starting and working windings. The standard marking of the terminal block leads is as follows:

1. Terminals U1 and U2 (or B1 and B2) are the main winding.
2. Terminals W2 and V2 (or C1 and C2) - starting winding.
3. Terminals V2 and V1 are the starting capacitor.

The connection of the starting winding remains constant, while the polarity of the supply of the working winding can be reversed to change the direction of rotation.

Note: the polarity is determined by the position of the jumpers on the motor terminal strip, which will be closed remotely via a contactor.

Launch equipment

To assemble the electrical circuit, you will need two IEK KMI 1121 magnetic starters with a coil supply voltage of 230 V, or one PML 2561 reversing starter (the advantage of the latter is the presence of a mechanical interlock). There should be three main contacts.

It is also necessary to have an auxiliary contact block, which includes one normally open and one normally closed contact. Additionally, you will need a push-button case IEK KP103 with three buttons "Start", "Reverse" and "Stop". To install the post from the street side, it is recommended to complete it with buttons with a turnkey lock. All switching electrical equipment must be mounted in a metal box with IP54 protection and cable glands.

Connect the input contacts of two starters in parallel, supplying them with phase and zero from the 220 V network through a circuit breaker. On the reverse side of the starters, connect the two power wires of the starting winding.

On the example of the AIRE 80 motor, power must be applied to terminals V1 and W2. Please note that the polarity remains the same regardless of which starter is turned on. Conclusions U1 and U2 belong to the ends of the working winding and must be connected to two starters in a different sequence.

Power to the coils of each starter must be supplied through its own normally open and normally closed contacts of the second starter. This will provide self-pickup and hold the coil in the on state, as well as provide an electrical blocking of the oncoming start.

Pushbutton posts and limit switches

The drive is controlled by one or more push-button posts. The phase wire is passed through the normally closed contacts of the "Stop" buttons, which are connected in series, which is necessary for the possibility of breaking the coil holding circuit from any button.

Next, power is supplied to the normally closed contacts of the "Start" and "Reverse" buttons, then power is supplied from the terminals of each button to the normally open pair of the opposite one. These contacts control the activation of the coils of the respective starters. Cross connection via break contacts is necessary to avoid unintentional switching of the starters.

In order for the drive to turn itself off in a timely manner when the gate reaches the extreme opening and closing points, the electrical circuit must be supplemented with limit switches. Suitable switches VPK-2112 or ME 8104 with one normally closed contact. It is recommended to use products equipped with a roller.

The limit switches must be firmly fixed on the stationary door frame in such a way that the roller is 1-2 mm from any longitudinal element of the door. It can be a carrier frame or a rail guide, the main thing is that the side surface is absolutely flat. The gate must be placed first in the open, then in the closed position and mark the points of contact with the rollers.

Note! Since massive gates continue to move by inertia, it is recommended to move the marks a few centimeters in the opposite direction so that the limit switch operates with a little lead.

According to the applied marks, it is necessary to weld small protrusions, the height of which will be sufficient for the sure operation of the switch. It is also important that the mark is long enough to hold the roller, and not slip through it, briefly turning on the limit switch. The switch must be in the trip position until it starts moving in the opposite direction, when it leaves the mark and closes the circuit again.

The electrical connection of the limit switches can be done in two ways.

Wiring diagram for pushbutton posts and limit switches

Method number 1. Normally closed contacts are connected in series and included in the holding circuit of the contactor coils. The switching point is located between the series-connected "Stop" buttons and the normally open contacts of the starters. The disadvantage of this method is that when the gate is turned on, it takes a certain time to keep the button pressed until the switch leaves the triggered position.

Method number 2. It implies the independent inclusion of limit switches in the coil holding circuits of each starter. The normally closed contact of the switch is located in the scheme between the normally open auxiliary contact of the starter and the coil terminal. It is also allowed to put the switch in the electrical interlock circuit: between the coil of one and the normally closed contact of the second starter. Thus, the switches operate independently of each other, which means that no time delay is required when the drive is turned on.

Gate control via frequency converter

Since frequency converters have recently become more affordable and popular, it is appropriate to use them to control the gate drive, especially since there is more than one reason for this:

1. Because the frequency converter supplies three-phase voltage to the drive, you save money by purchasing a more common, smaller motor.
2. The engine speed is irrelevant.
3. Difficulties with connecting a three-phase motor are excluded.
4. You avoid problems with starting the drive under load.
5. The converter smoothly but quickly accelerates and stops the gate, opening occurs in a matter of seconds.
6. No need to buy and install a gearbox.
7. No starters needed, simple wiring diagram.
8. Significantly increases the service life of the engine.

The average cost of a device with an output power of 2-2.5 kW is $250-300, so its purchase is fully justified, given the refusal to purchase a gearbox and starters.

The CFM-240 frequency converter is a budget version of the device, it also has the most common connection and control scheme. Following his example, you can easily deal with similar devices.

Connecting the frequency converter

Terminals L and N are used to supply, respectively, phase and zero from the 220 V network, it is important to observe the polarity here. Terminals U, V and W provide the output voltage for powering a three-phase asynchronous motor for voltage 380/220 V, the windings of which are connected in a delta. Control occurs by closing one of the control contacts DI1-DI3 to a common GND terminal. Accordingly, when DI1 and GND are connected, the motor starts, DI2 and GND will start the drive in the opposite direction, and DI3 and GND will stop it.

Frequency converter setting principle

The inverter is configured by changing the values ​​of each of the 70 parameters. A complete description of the functions and set values ​​is given in the device data sheet. To adjust the values, enter the parameter selection menu by pressing the "Mode" button until the display shows P---. Then you need to press "enter" and use the "up" and "down" arrows to select the number of the desired parameter, press "enter" again, set the desired value and press "enter" again to save.

Using a frequency converter gives you some additional options. For example, you can use the positioning function by transmitting data from a gate position sensor to the inverter. This will allow you to use the device in stepper motor mode. He will smoothly accelerate the gate and gently stop them at the extreme point, remembering both extreme positions of the leaf. This is a more convenient and advanced replacement for the limit switch system. It is only required to install a counter of the "quadrature encoder" type on the drive shaft.

The meter has two power wires that are connected to the +12V and GND terminals, as well as two signal wires that are connected to the DI5 and DI6 terminals. The positioning function is enabled by assigning a value of "2" to parameter 60. Next, a value of "1" to parameter 61 must be set to set the desired sensor type. Then, by changing the values ​​of parameters 62 and 63, determine the relationship between the number of pulses and the distance traveled.

For example, the motor shaft can move the gate by 25 cm per revolution, and the encoder mounted on the shaft produces 200 pulses per revolution. This means that for every 1000 mm set in parameter 62 there will be 800 encoder pulses set in parameter 63.

Parameter 66 defines the type of braking and should be set to "1". Parameter 67 determines the engine speed to which the maximum operating speed will be reduced, and the value of parameter 68 determines the required braking distance. After setting these parameters, you can go to the main menu and specify the distance that the gate must travel, in millimeters. After the task is completed, the counter will reset to zero and will be ready for a new cycle, counting is carried out in both directions.

The rated speed of the motor is set by the value of the output frequency (Hz) in the main menu of the program. You can change it in real time and increase it as long as the transfer mechanism keeps stable. Also remember that too much acceleration will prevent the inverter from effectively decelerating at the end of the path. The time for the drive to accelerate to maximum speed is given by the value in seconds of parameter 10.

Setting the gate braking with a frequency converter

Doors that are too massive need to be braked by the drive. To do this, the frequency converter has a function enabled by parameter 21. The amount of braking force and the time it takes to come to a complete stop are set in parameters 27 and 28 respectively. When braking by the drive, load compensation must be used. To do this, power resistors with a resistance of at least 70 ohms and a power of over 350 W must be connected to the power terminals Br (they can also be replaced with a bunch of 4-5 incandescent lamps connected in series).

Now you have several options for connecting the engine and you can choose the method that suits your needs. Each connection method can have a remote control scheme, which we will discuss in the next article.

Sliding gates are quite popular in use. However, their cost is quite high, so it is much cheaper to build the gate yourself. There are several schemes for organizing an automatic drive. We will learn how to make automatic sliding gates with your hands further.

Do-it-yourself automation for sliding gates - features and characteristics

With the help of a mechanized electronic drive, it is possible to ensure the opening of massive gates by pressing a button. To assemble it, you will need improvised materials, and installation work will take a maximum of a day. The main part for an automatic drive is an asynchronous type motor. Consider two options for signaling - chain and roller.

Before manufacturing the drive, it is necessary to select a suitable motor. If there is a three-phase meter on the site, we recommend that you stop at a three-phase version of the motor, the windings of which have a star connection. Thus, it is possible to get rid of a large number of problems during start-up, and the engine power will be used with maximum efficiency.

In the absence of a three-phase meter, use a single-phase capacitor-type motor. Please note that such devices are characterized by low performance, especially during start-up. The optimum drive power is between 1 and 2.5 kW. This value is determined by the total weight of the web. The engine speed should be at least 500-1000 rpm. With the help of low torque, it is possible to get rid of the load on the surface of the drive shaft.

The drive wheel should make no more than one hundred revolutions per minute. This value is the output torque on the gearbox. The value of the input torque must be equal to the motor speed. This do-it-yourself scheme for connecting sliding gate automation involves the use of single-stage gearboxes.

If these parts could not be found, then it is possible to replace them with less expensive options. However, the kinematic circuit must be securely connected. The main component of this mechanism will be the power motor from the old washer. When connecting this motor, determine the ends on each winding. For these purposes, a multimeter is used that measures the resistance force, the starting type winding of this engine will differ in a large value.

A rigid or semi-rigid coupling is used to connect the gear shaft to the motor. The first option has the form of a sleeve, on which there are holes of various sizes, as well as keyways. The second version of the coupling consists of two flanges, for the connection of which rubber petals are used.

A belt drive will help replace the gearbox. At the same time, in order to correctly determine the gear ratio, the size of the large pulley mounted on the drive wheel is divided by the size of the smaller one located on the motor shaft.

This option is distinguished by the complexity of the assembly of tripod elements, as well as in the connection between the details of the kinematic scheme. Quite a few problems arise with the connection of belt tensioners. For this, an automobile tensioning mechanism for belts is added to the mechanism.

In addition, when using a belt drive, special attention is paid to the mechanism with an independent shaft, on which two bearings are located. Particular attention is paid to the centering of the shaft, as it has two transmissions.

Do-it-yourself homemade automation for sliding gates

We offer you to get acquainted with the manufacturing option of the simplest method of automation of sliding gates. This transmission is called rack or chain. A bicycle or motorcycle sprocket is fixed on the gear shaft. Next, you need to put on a special chain on it, the diameter of the links of which corresponds to the type of sprocket. It must be fixed in a horizontal position along the entire door leaf. By rotating the sprocket in one direction or another, the rotation of the chain is transmitted, which opens the gate.

Pay special attention to fixing the engine on the gear mechanism. Initially, it is necessary to create a frame on which the engine with the transmission mechanism will be located. For these purposes, we recommend using a 5 cm angle steel. Fix the frame firmly to the concrete base. The duration of the operation of the entire mechanism depends on this. When choosing a gearbox with a motor, first of all, be guided by the height of axial rotation. If there are different values ​​between these two mechanisms, then it is necessary to build a two-level base under the equipment.

Bolts with special nuts are used to fix the gearbox and motor. At the same time, the support under them should be distinguished by jealousy and rigidity. Under the base, you need to build oblong-shaped holes to properly adjust the position of the motor.

At the next stage, the chain is installed on the gate. Most often, it is fixed on a rail-type guide. However, this is a big mistake, as the mechanical transmission is constantly dirty and quickly fails. An additional drive-type beam is mounted directly on the canvas, while the installation height of the chain installation is 50-80 cm from the ground.

A chain with a gear-type rail is installed on the lower part of the beam; a rubber or plastic casing is used to protect it from extraneous factors and moisture. Electric welding is used to fix the end sections of the chain with the gate. Please note that all connections must be of high quality, therefore, in the absence of experience with a welding machine, it is better to entrust this process to a professional.

Chain transmission is characterized by a large number of difficulties that arise during its operation. First of all, the chain is stretched under the influence of a heavy gate. To eliminate this phenomenon, it is enough to install a hairpin on the last link of the chain, inside of which the lugs are placed. With this tensioner, the target is gradually tightened. Another option is to mount a special roller on the chain with a rigid spring. It is she who pulls the chain during operation, preventing it from stretching.

Another unpleasant phenomenon is the slipping of the chain from the sprocket. In this case, it is better to replace the chain with a gear rack; for these purposes, you need to contact a professional locksmith.

There are several types of automation for sliding gates with their own hands, schemes that differ in the presence of pressure rollers in the drive system. For the manufacture of such mechanisms, you need to spend more time and effort. The advantage of such a scheme is its dirt resistance, resistance to moisture, snow and ice.

This mechanism involves the installation of the roller on the outer wall of the rail parts. The roller has a protective cover made of rubber. The tire should have a straight tread profile that provides reliable grip. For additional force, spring compression is used. The spring is mounted on a push pin and connected to the nut mechanism. To fix the axial shafts, a P-shaped lock is used.

In order to compensate for these forces, two counter-type rollers are mounted on the reverse side of the guide element, fixed in a stationary position.

In order to purchase suitable rollers, you should contact the industrial enterprises dealing with trolleys. Try to choose wheels with a steel base and sealed bearings. The maximum load on such a roller should be 350-600 kg, in relation to the weight of your gate. Also pay special attention to the springs mounted on the pusher. They must have high clamping force. However, the load capacity of the spring must not exceed the load capacity of the bearing.

Pay special attention to connecting the motor to the roller mechanism. For these purposes, a V-belt transmission is used. To fix the driven pulley, a steel base is used, as well as wheels with three studs. Also, take advantage of several exposed gears. When choosing a place for fixing the roller, we recommend stopping at the gear shaft or directly on the motor. Thus, the surface of the tensioning mechanism will not interact with the axial roller shaft, but with the base of the gearbox housing. Note that the radial pressure on the bearing must not exceed the clamping force of the spring mechanisms.

Do-it-yourself installation of automation on sliding gates

Please note that before installing automation, you need to check simple sliding gates with your own hands without automation for defects in the process of opening them. Before starting installation work, you need to take care of the alignment of the gate strictly according to the level and their correct installation.

In the process of standard equipment for automatic gate opening, there are most often:

• electric drive;
• a rail on which the teeth are located;
• some models are equipped with a remote control;
• security elements;
• lamps - signal type.

In addition, in the process of work, you need to stock up on a welding machine, a drill and a set of drills for it, drives that connect the lamp and safety elements.

Initially, decide on the place of installation of the electric drive on the gate. After that, install the drive and set up the automatic elements. Install the rack with teeth on the surface of the drive, determine the mounting location of the drive so that the rack is in the center of the gear.

After that, the drive is fixed at the previously defined location. For these purposes, a welding machine is used. If it is necessary to mount the drive a little higher than a certain place, it is mounted on the surface of a previously welded profile pipe. After mounting the channel, a drive is installed on it, fixed with bolts.

The next step is to install the rack with teeth. First of all, open the gate, center the rail on which the gear is located. In order to fasten the limit switches, install a rail.

The rail is welded onto the surface of the pipe, then it is pulled behind the canvas. After mounting the rail, its performance is checked. All elements on which the automation is fixed are welded again. A gap of one millimeter is left between the drive and the gear surface.

Next, limit switches are installed. Bolts are used to fix them on the surface of the rail. There are two types of switches - magnetic and mechanical. The first option is more efficient, as these switches work even under adverse weather conditions. The magnet is installed on a rail with teeth, passing a certain section on the gate, it starts to work, while the switches are divided into two types: plus and minus. The adjustment of these elements of the system is carried out at a distance of at least 100 cm from the gate. A conventional spring is used to operate the mechanical type switches.

It is necessary to connect the electric drive according to the instructions from the manufacturer. For additional settings, use the remote control. In addition, photocells are additionally installed that capture light signals. The photocells must be fixed opposite each other. They can be installed on previously equipped poles. In order to connect the wires, build a hole in the pipe and run them from the power supply.

Next, you should install a signal type lamp, it will transmit information about nearby objects. This element is optional, but it significantly increases the safety level of the site.

For do-it-yourself automation for sliding gates, the price is determined individually, in relation to the power of the main drive. This factor is determined by the size of the gate and its total weight. Do-it-yourself sliding gates without automation are quite difficult to use, since each time you need to use physical effort to open them.
