A road and bridge anti-collision protection device

Abstract

The invention discloses a road bridge anti-collision protection device and relates to the technical field of road bridges. The device comprises protection mechanisms evenly arranged on the left side and the right side of a road; each protection mechanism on the right side comprises an installation box fixedly connected with the side edge of the road; a negative pressure box is fixedly installed atthe bottom in each installation box; a communication pipe is arranged at the upper end of each negative pressure box; a truncated-cone-shaped sealing column is matched with the inside of each communication pipe in a sealed mode; the upper end of each installation box is in sliding connection with a supporting board; the middle portion at the lower end of each supporting board is fixedly connectedwith a strut; the lower end of each strut is fixedly connected with a reversed-T-shaped clamping board; a left-right run-through T-shaped locating groove is formed in the upper end of each sealing column; a pressure spring is fixedly installed on the upper portion of the left side wall in each installation box; the right end of each pressure spring is fixedly connected with the side face of the corresponding strut; and the right end of each protection transverse board is fixedly connected with the middle portion of the side face of a supporting column. The road bridge anti-collision protection device has the beneficial effects that wheels sink and are suspended so that a vehicle can be prevented from continuously moving and colliding, the vehicle is prevented from being turned over through the up-down pressure difference generated after the negative pressure boxes are opened, and a protection effect is achieved.

Description

Technical field [0001] The invention relates to the technical field of road and bridge protection. Background technique [0002] The left and right sides of the road need to be equipped with protective fences to protect vehicles from driving and avoid falling off the lane and falling into the side of the road or under the bridge to improve safety. However, conventional protective fences cannot provide good protection. It is easy to walk, and generally the height of road and bridge guardrail is low. When the vehicle is running, it often collides with the guardrail in emergencies. In the case of loss of control or the driver's wrong operation, the vehicle is likely to hit the guardrail and change the driving direction at a large angle, and hit the normal driving vehicle on the road , Or repeatedly hit the guardrail, causing serious traffic accidents, and sometimes the collision may also cause the vehicle to flip and fall to the side of the road, causing great harm to life safety. ...

Problems solved by technology

[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
