ABS material for preventing bridge guardrail from being rushed out

Abstract

The invention discloses an ABS material for preventing a bridge guardrail from being rushed out, the ABS material comprises two base shells which are symmetrical in left and right positions and fixedly connected with the ground, the top of each base shell is fixedly connected with a shell made of the ABS material, and an extension groove which penetrates through the top wall of the base shell and is provided with a downward opening is formed in each shell; a locking device can freely change the connection state between the second belt wheel and the spline shaft, so that the motion state of the corresponding spline shaft is changed, and the switching of two working states of detecting whether a fault occurs or not and buffering the vehicle when the vehicle encounters an impact is facilitated; an anti-impact device can prevent vehicles from rushing out of the fence and falling to the position below a bridge to hurt other vehicles and people, meanwhile, people in the vehicles are protected against secondary hurt caused by falling, and the stopping device can'hold 'the vehicles rushing out of the edge of the road through iron chains to prevent the vehicles from leaving the protection range of the fence.

Description

technical field [0001] The invention relates to the technical field of ABS materials, in particular to an ABS material for preventing from breaking out of bridge guardrails. Background technique [0002] Setting up guardrails on the road is a practice adopted by most cities in my country at present. Using guardrails to prevent vehicles from turning around at will and pedestrians from jaywalking is already a traffic management measure and a necessary method that has been practiced in major cities at present. In addition to blocking it It plays the role of protecting human driving, preventing and reducing traffic accidents as much as possible, and reducing casualties. However, ordinary fences require regular and gradual inspections by staff, which is time-consuming and laborious, and the existing guardrails cannot effectively protect bridges or other high roads. In terms of traffic safety, there are frequent accidents where vehicles on bridges or high roads still rush forward af...

[0002] Setting up guardrails on the road is a practice adopted by most cities in my country at present. Using guardrails to prevent vehicles from turning around at will and pedestrians from jaywalking is already a traffic management measure and a necessary method that has been practiced in major cities at present. In addition to blocking it It plays the role of protecting human driving, preventing and reducing traffic accidents as much as possible, and reducing casualties. However, ordinary fences require regular and gradual inspections by staff, which is time-consuming and laborious, and the existing guardrails cannot effectively protect bridges or other high roads. In terms of traffic safety, there are frequent accidents where vehicles on bridges or high roads still rush forward after hitting the guardrail, resulting in falling accidents. This will not only cause serious secondary injuries to vehicles and drivers, but also cause serious injuries to vehicles and pedestrians below. , or even cause an explosion
