Anti-collision device for highway vehicles

Abstract

The invention discloses an anti-collision device for expressway vehicles. The upper horizontal guardrail belt is equidistantly opened along the length direction with upper wire rope through holes, the middle horizontal guardrail belt is equidistantly opened along the length direction with middle steel wire rope through holes, and the lower horizontal guardrail belt is equidistantly opened along the length direction. The lower steel wire rope holes are equidistant along the length direction, and the upper, middle, and lower wire rope holes are dislocated; the upper, middle, and lower horizontal guardrail belts are connected by the first buffer wire rope and the second buffer wire rope. The wire ropes respectively pass through the corresponding wire rope holes on the upper, middle and lower horizontal guardrail belts in turn. In this case, the first and second buffer wire ropes are arranged in a serpentine structure, which facilitates the positioning of the first and second buffer wire ropes, thereby effectively absorbing the energy of high-speed collisions, and the three horizontal guardrails + the first and second buffer wire ropes + The first and second buffer wire ropes are arranged in a serpentine structure + the first and second buffer wire ropes pass through the same wire rope hole on the middle level guardrail belt to organically cooperate.

Description

technical field [0001] The invention belongs to the field of expressways, in particular to an anti-collision device for expressway vehicles. Background technique [0002] With the development of society and technology, expressways are becoming more and more popular. The speed of vehicles on the highway is relatively fast. Once an accident occurs, it is likely to rush out of the road and cause serious traffic accidents. In order to avoid the above situation, highway anti-collision barriers are generally installed on both sides of the expressway at present. The pile foundations of this anti-collision barrier are fixed on the ground, and the pile foundations on each side are arranged equidistantly along the extending direction of the highway. The upper part is connected by a horizontal guardrail belt, which is formed by successively connecting several sections of horizontal guardrails, and the joints are connected by bolts. However, due to the fast speed of vehicles on the ex...

Problems solved by technology

However, due to the fast speed of vehicles on the expressway, the kinetic energy of crashing into the guardrail after a traffic accident is very large. A high-speed vehicle can easily crash into a certain section of the horizontal guardrail and rush out of the road, causing serious safety accidents. Urgent need to solve the above technical problems
