Description

TECHNICAL FIELD

This invention relates to the field of barrier and specifically relates to an anti-

collision barrier gate.

BACKGROUND

Currently, most common barrier gate products on the market use fixed connections between the arm and the drive mechanism. This connection has a simple structure and is easy to install and maintain. But when a vehicle collides with the arm, the impact force between the vehicle and the arm cannot be avoided in time, which can damage the arm and the drive mechanism, and may even pose safety risks to the occupants on the vehicle.

In the application process of the intelligent barrier gate system, when a vehicle or person is detected by radar, the arm is immediately lifted to avoid hitting the vehicle or person. The original arm was an elliptical rod with a length of 4 meters and a three-section structure, and with a wall thickness of 2 mm, and a weight of approximately 7 kg; In addition, there is an octagonal “STOP” light sign, which weighs approximately 1.9 kg; The total weight of the gate and light sign is approximately 8.9 kg. After long-term operation, the arm of the barrier gate system may sag, which can cause the radar to be mistakenly triggered, impacting the anti hitting effect of the barrier gate system and posing safety risks. Although the arm can be leveled again by adjusting the installation bolts of the motor inside the drive mechanism, there are still cases where the leveling is not timely and accidentally triggered. This problem needs to be fundamentally solved to improve the safety of product use.

SUMMARY

The “STOP” light sign 2 is sleeved on the arm 1; After the anti-collision barrier gate is installed, when a vehicle collides with it, the arm 1 is stressed due to the collision, and the arm 1 will squeeze the bushing 4-1 which is made of elastic material, and then the arm 1 can detach from the Bushing 4-1. and then the arm 1 will move around the rotating axis positioning hole 4-2 as the center and its position will be limited by the position adjustment hole 4-3, and the arm 1 cannot give the vehicle a reactive force. Therefore, the collision here will not cause damage to the collision barrier gate, and can also avoid injury to occupants on the vehicle due to the collision.
