Collision railing for reducing casualty rate of out-of-control vehicles beside road

Abstract

The invention discloses a collision railing for reducing the casualty rate of out-of-control vehicles beside a road and relates to the technical field of guardrails. The collision railing comprises arailing frame; a rotating frame is rotationally mounted on the railing frame; a first roller set, a second roller set and a third roller set are rotationally mounted on the railing frame; two throughholes are formed in the top side of the railing frame; and the top side of the rotating frame and the top side of the first roller set penetrate through the two through holes correspondingly and are fixedly provided with synchronous wheels correspondingly. According to the collision railing of the invention, when a vehicle collides with a collision plate, a first wedge block and a second wedge block move leftwards; in this process, the collision plate is subjected to the elastic action of a first spring and a second spring, and therefore, the impact force of an automobile can be effectively reduced; at the moment when column wheels enter temporary grooves, the two wedge blocks rebound under an elastic effect due to the fact that the first wedge block and the second wedge block are not provided with middle force transmission elements, and therefore, the impact damage degree of the vehicle is reduced, and the safety of a person in the vehicle can be effectively protected.

Description

technical field [0001] The invention relates to the technical field of protective barriers, in particular to a collision barrier for reducing the casualty rate of out-of-control vehicles on the side of the road. Background technique [0002] Guardrail, also known as urban traffic galvanized plastic-sprayed steel guardrail, it is beautiful, novel, easy to install, safe and reliable, and the price is favorable. Separation of toll gates, etc. [0003] In the prior art, the guardrail mainly plays the role of isolation. When the car hits the guardrail, the guardrail cannot protect the car very well, and even causes serious damage to the vehicle, and may seriously cause the occupants of the car to Casualties, and even cause injury to pedestrians or other vehicles because the guardrail is knocked down by the car, and then cause secondary accidents. Therefore, a collision railing that reduces the casualty rate of out-of-control vehicles on the roadside is needed to meet people's ne...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a collision railing for reducing the casualty rate of out-of-control vehicles on the side of the road, so as to solve the problem that when the car hits the guard rail, the guard rail cannot protect the car well, and even cause serious damage to the vehicle. It may cause casualties in the car, and even cause injury to pedestrians or other vehicles because the protective fence is knocked down by the car, which will cause secondary accidents.
