Description

Anti-collision device for highway bridge Technical Field The utility model relates to the technical field of anti-collision devices, in particular to an anti-collision device for a highway bridge. Background Along with the development of science and technology, automobiles become necessary transportation means for people to travel, but safety problems are easily caused in the running process of the automobiles, and when the speed of the automobiles is too fast or the automobiles are in fatigue driving, the automobiles are easy to flush from two sides of a highway or a bridge, so that serious loss is caused to lives and property of people, and therefore, anti-collision guardrail devices are often erected on two sides of the highway or the bridge. For example, CN208121638U in chinese patent discloses an anti-collision device for highway bridge, which comprises a plurality of fixed columns fixed on the ground, a mounting plate slidingly connected with the fixed columns in horizontal direction, a plurality of bent connecting lugs arranged on the mounting plate, a buffer pad clamped between the connecting lugs and the mounting plate, a bearing seat arranged in front of the connecting lugs and a buffer roller arranged between the two bearing seats in vertical direction in a rotating way, wherein the buffer roller comprises a rotating shaft made of metal materials and a rubber sleeve sleeved outside the rotating shaft, when a vehicle collides with the device, the buffer roller rotates, the guided vehicle moves towards the running direction of the highway bridge, the collision force is gradually changed into the power of upward movement of the vehicle, the collision is slowed down, and the property and life safety of people are ensured.
