Parking barrier common problems and maintenance methods

The common problems of barriers and their maintenance methods are as follows:

1. Loosening of the gate burying thread: When the local sensation coil is not fixed, vibration will occur whenever the vehicle presses the road surface, which will cause the coil in the nest to distort and change the initial inductance of the Sense coil. In this case, it will only work if the sensor is reset.

Solution: When the sensor resets, the asphalt will be melted and poured into the nest, after cooling, it will be fixed.

2. Looseness of Looseness Screws of Daozha: The Daozha abutted screws are positive and negative threaded connections. The two upper and lower bearings are connected by double-headed screws. If the screws loosen, the upper and lower positions will be inaccurate.

Solution: Use a 800mm*Ф4 iron rod to insert between the double-headed screws, and turn the adjustment lever up and down in place.

3. Looser screws of the gate brake are loose: When the brake lever screws of the gate brake are loose, the upper and lower positions of the gate of the gate brake will be inaccurate and a large shaking will be generated when the brake rod is stopped.

Solution: This situation is relatively simple, as long as the bolt is suspended, the nut can be locked.

Fourth, in place to control the magnet shifting position: The up-and-down position of the gate is used is Cimin Hall element, if the rectangular magnet and reducer cam with a change in the position of the wafer, will result in in place is not accurate.

The solution: adjust it accurately, not flip, you can solve the problem.

5. Power-off protection switch power-off: When the control part of the barrier valve fails, the automatic protection device of the barrier valve will automatically start working. At this moment, the brake rod stops at the oblique position and the main power is disconnected. The machine does not work. .

Solution: In this case, the machine door is opened first, and the large belt can be restored by rotating the large belt 3-8 times in the clockwise direction to the upper position. When this method cannot be used, it is necessary to check whether the Hall element and the circuit board have malfunctioned.

6. The pull-down hook adjusts the looseness of the nut: the lower part of the chassis is provided with a pull-down hook of thread M10, which functions to pull the spring of the balance mechanism and the zero adjustment of the balance function. Two M10 hex nuts and ten spring washers are installed. If the screws on the hex nuts are loose, they will cause a misalignment and cause the load of other components such as the speed reducer and the motor to affect the service life of the barrier.

Solution: Tighten the screws.
