Road and bridge anti-collision protection device

Abstract

The invention discloses a road and bridge anti-collision protection device and relates to the technical field of road and bridge protection. The road and bridge anti-collision protection device comprises protection mechanisms which are evenly arranged on the left and right sides of a road and comprise mounting boxes fixedly connected with the side edges of the road. Negative pressure boxes are fixedly mounted at the inner bottoms of the mounting boxes, and communicating pipes are arranged at the upper ends of the negative pressure boxes; supporting plates are slidably connected to the right sides of the upper ends of the mounting boxes; the left sides of the lower ends of the supporting plates are fixedly connected with supporting columns, and the lower ends of the supporting columns are fixedly connected with sealing plates; the sealing plates and the upper end faces of the communicating pipes are horizontally and slidably matched in a sealed mode; the left ends of the supporting plates are rotatably connected with turn-over plates through rotating shafts; and the right ends of protection transverse plates are fixedly connected with the middles of the side faces of the supportingcolumns. The road and bridge anti-collision protection device has the beneficial effects that vehicles are prevented from continuously moving and colliding in a mess mode through wheel subsidence suspending, through the up-down pressure difference after the negative pressure boxes are opened, the vehicles are prevented from being turned over, and thus the protection effect is achieved.

Description

technical field [0001] The invention relates to the technical field of road and bridge protection. Background technique [0002] Guardrails need to be set up on the left and right sides of the road to protect the vehicle from driving and avoid falling off the roadside or under the bridge to improve safety. However, conventional guardrails cannot provide good protection. It is convenient to walk, and the height of the general road and bridge guardrail is relatively low. When the vehicle is running, in an unexpected situation, it often collides with the guardrail. In the case of a loss of control or the wrong operation of the driver, the vehicle is easy to hit the guardrail and change the direction of travel at a large angle, but hits the normal driving vehicle on the road. , or repeatedly hit the guardrail, causing serious traffic accidents, and sometimes the collision may cause the vehicle to overturn and fall to the side of the road, causing great harm to life safety.
