Demand for Gates - Tigerwong

The demand for road gates is also increasing. With the continuous development of automobile industry and the increasing number of cars. It also puts forward higher requirements for the performance of the gate. For example, the integrated movement of the gate, the clutch device, the intelligent anti lifting function, the return device in case of resistance, the temperature rise function (to ensure that it can be used in the environment of minus 40 degrees), the exhaust cooling system (to reduce the motor temperature in time), the automatic clutch device, the anti-collision rod release device, etc. The take-off and landing speed of the rod ranges from 0.8 seconds to 6 seconds. The length of the pole is 0-7m, which is determined according to the actual channel width on site. The road gate has been increasingly developed to high technology to meet the market demand for products. It has become a key Lane equipment in the parking lot system management. The intelligent gate has led display and voice broadcasting functions. According to the performance of the control part, it is divided into electromechanical gate, digital gate and intelligent gate. According to the gate rod, it is divided into fence gate, straight pole gate and curved arm gate. According to the take-off and landing speed, it is divided into fast gate, medium speed gate and slow gate. According to the device direction, it is divided into left gate and right gate. The inductance of the coil shall be kept between 100uh300uh. When the coil inductance is constant, in order to make the detector work in the best state. The number of turns of the coil has an important relationship with the circumference. The smaller the perimeter, the more turns. Since various metal substances such as cable pipelines, steel bars and sewer covers may be buried under the road, which will have a great impact on the actual inductance value of the coil, the data in the above table are only for users' reference. During actual construction, the user shall use the inductance tester to actually test the inductance value of the inductance coil to determine the actual number of turns during construction. As long as the final inductance value of the coil is guaranteed to be within a reasonable working range (e.g. between 100uh300uh), a sufficient length of conductor shall be reserved for connection to the loop inductor and winding the coil. It can also ensure that there is no joint in the middle. After winding the coil cable, the outgoing cable must be made into tight twisted pair, and it is required to be twisted for 20 times at least 1 meter. Otherwise, the output lead without twisted pair will introduce dry closing, which will make the coil inductance unstable. Generally, the length of output lead shall not exceed 5m. Since the sensitivity of the detection coil decreases with the increase of the lead length, the length of the lead cable should be as short as possible. Prevent sharp corners from damaging the coil cable. The slot width is generally 48 mm. For coil embedding, first cut the slot on the road with a road cutter. Chamfer the four corners 45 degrees. Depth 3050 mm. At the same time, cut a slot for the coil lead to the roadside. However, it should be noted that the groove must be clean and free of water or other liquid infiltration. When winding the coil, the coil must be straightened, but not too tight and close to the groove bottom. After winding the coil, lead out the twisted output lead through the outgoing slot. During the winding process of the coil, an inductance tester shall be used to actually test the inductance value of the inductance coil and ensure that the inductance value of the coil is between 100uh300uh. Otherwise, the number of turns of the coil shall be adjusted. Open the box door and place the box in a certain position. Use a marker pen or screwdriver to mark the hole on the bottom plate of the box, and remove the box. The hole depth is 70-80mm, and the expansion screws are placed. The impact drill is used to drive the expansion screws at the outlet. Adjust the levelness and verticality of the box and tighten the nuts. Install the brake rod to clamp the brake rod in the box to the horizontal position. Open the handle of the box door rocker motor. Put on the outer brake rod clamp and flat washer, and put the end of the brake rod with screw hole horizontally into the brake rod clamp slot in the box. And tighten the nut. Keep the gate lever in the horizontal position. And make the gate rod support just in contact with the gate rod. Adjust the gate rod support. The device method of the gate rod support is the same as that of the box. Press the ▼ "key of the controller to adjust the gate tension spring and connect the power supply of the gate. Make the brake rod run up and down 90 degrees for 4 to 5 times. If the rod shakes when it falls, it indicates that the tension of the balance spring is not enough, and run the brake rod to the vertical state. Turn on the box machine and disconnect the power supply. Loosen the screws of the box cover and remove the box cover. Use a hex wrench to adjust each tension spring screw. As shown in Figure 3, the brake rod achieves the best effect during rod falling operation. It indicates that the tension of the balance spring is too large, and if the rod shakes during the lifting time. Repeat the above operation (loosen the spring screw to achieve the best effect when the brake rod is falling. If the motor is running and the brake rod does not act, if the rod is rising, it indicates that the tension of the balance tension spring is insufficient, adjust the tension spring state or increase the tension spring until the brake rod operates normally. The configuration of single spring is as follows: two tension springs are configured for the gear rod with a length of 4-5m, and two tension springs are configured for the brake rod with a length of 6m. The length of the brake rod is 4m A tension spring is configured below to avoid unbalanced force. During adjustment, the number of turns of each nut is the same. The limit adjustment of the gate reaches the balance range, and the balance state of the gate rod is adjusted when the gate leaves the factory. If the lifting and falling of the gate rod is not vertical or horizontal in the field device, the method is as follows: open the box door; slightly rotate the limit baffle to adjust the gate rod to the level Position, use a cross screwdriver to loosen the crosshead screw of the limit baffle. After adjustment, tighten the screw; fine tune the limit baffle in the reverse direction, when the gate lever is not in place. If it exceeds the horizontal position, the reverse is true; fine tune the limit baffle in the clockwise direction, when the gate lever is not vertical. Adjust it to the required position; lock the box door. If your gate fails to repair, if your gate has the following three kinds of problems: In addition to the fault, the general simple gate fault can be solved according to the following three methods. It is recommended to ask a professional to repair. Troubleshooting methods for the landing rod: measure whether the voltage is within the range of 220V ± 10V; if it is not in place and jitter is too large. Troubleshooting methods: adjust the position of travel control and tighten the tension spring link bolt; detection reason: check whether the magnet of operation switch is properly adjusted and whether the balance spring Check whether the spring tension is too loose or too tight. The cause of abnormal sound in the chassis: check whether the bearings and movable links are abnormal. Troubleshooting: add lubricating oil or replace the bearings. The rare faults of the gate and their maintenance methods are as follows: the vibration of the car over the road will cause the coil in the nest to deform, and the coil embedded wire of the gate is loose: the local sensing coil cannot be firmly fixed in the nest Change the initial inductance of the ground inductance. At this time, the sensor must be reset before it can work normally. The solution is to pour melted asphalt into it to fix it. The upper and lower bearings are connected with double headed screws, and the movable joint screws of the gate are loose: the movable joint screws are connected with positive and negative threads. If the screws are loose, the upper and lower positions will be inaccurate. Use an 80mm long ф 4. Insert the iron bar between the double headed screws and rotate the brake rod to adjust it up and down in place. It will cause inaccurate upper and lower positions of the brake rod of the road gate and large shaking when stopping the rod, and the crank arm screw of the road gate will be loose: if the screw is loose, suspend the bolt and lock the nut. If the position of the rectangular magnet and the disc with cam of the speed reducer changes, the position control magnet will be moved: cimin hall will be used for both up and down in place Component. It causes inaccuracy in position. The problem can be solved by adjusting it accurately and not turning it over. The automatic maintenance device of the gate will work automatically, and the power-off maintenance switch will be powered off: when the control of the gate fails locally. At this time, the gate rod stops at the inclined position, the main power supply is disconnected, and the machine does not work. At this time, open the machine door and rotate the large belt clockwise for 3-8 turns to the upper position It can be restored. If it cannot be restored for so many times, it is necessary to check whether the hall element and circuit board fail. Its function is to pull the spring of the balance mechanism and adjust the zero point of the balance function. It is equipped with two M10 hexagon nuts and ф 10 spring washer, pull-down hook, loose adjusting nut: a threaded M10 pull-down hook is set at the lower part of the chassis. If the nut is loose, knocking sound and balance imbalance will occur when the machine is running. Although the machine can still run after balance imbalance, it will greatly increase the load of reducer, motor and other transmission parts, thus affecting the operation reliability and mechanical life of the gate.
