Description

An anti-collision height limit rod

technical field

The invention relates to the technical field of transportation equipment, in particular to an anti-collision height-limiting rod.

Background technique

The height limit rod is a warning rod before entering a bridge or tunnel to avoid cars hitting the bridge or tunnel. For example, the Chinese utility model patent No. 2019202269538 discloses a safety height limit rod, which includes a first support rod and a second support rod. Two support rods, the top ends of the first support rod and the second support rod are fixedly connected with fixed piles, and the first support rod and the second support rod are respectively sleeved with a first limit on the outside of the two fixed piles The height rod and the second height limit rod, the two fixed piles are respectively connected with the first height limit rod and the second height limit rod with a torsion spring. Compared with the existing device, the height limit rod is divided into two parts. It is divided into two parts, so that the vehicle can be separated after the collision with the height limit rod, thus avoiding the accident of roof cutting;

Through the research on the existing height limit bars such as the above examples, it is found that they do not have the function of buffer braking. When the car hits the height limit bar, it often causes damage to the car and the driver due to the failure to brake in time, such as the above example. Although the height limit rod is easily knocked away, the bridge or tunnel to be protected behind the height limit rod cannot be knocked open. If a rigid block is used to force the vehicle to brake, the inertial force at the moment of braking is very large. damage to the driver;

Therefore, we urgently need to invent an anti-collision height limit rod that can buffer deceleration and braking to avoid damage to the driver and the vehicle to solve the above technical problems.
