Highway anti-collision device

Abstract

The invention relates to a highway anti-collision device, and belongs to the technical field of a highway guardrail. The highway anti-collision device comprises an anti-collision buffer unit, connection units and uprights; the anti-collision buffer unit is positioned at one side close to a highway and is connected with the uprights by a plurality of connection units up and down; the anti-collisionbuffer unit consists of a pressure reduction plate, sliding blocks, damping springs, a base, tension springs, screws, a buffer layer and reflective stripes; the pressure reduction plate and the buffer layer are of a semi-circular shape; flat straight sections are arranged at both the top and the bottom of the pressure reduction plate and the buffer layer, and the pressure reduction plate and thebuffer layer are fixedly connected with joints with the sliding blocks by the screws; the base consists of chutes, protrusions and limiting baffles. According to the invention, an impact force of a vehicle which is out of control can be effectively absorbed, damage to the vehicle in the impact process can be reduced and damage of a rigid guardrail plate to a vehicle body and passengers can be effectively prevented; safety performance of the highway guardrail is improved; damage of the anti-collision structure, which is caused by excessive deformation, can also be prevented; the highway anti-collision device is good in using effect and high in practicality.

Description

technical field [0001] The invention relates to an anti-collision device for expressways, belonging to the technical field of expressway guardrails. Background technique [0002] With the massive construction of highways and urban interchanges and the substantial increase in global car ownership, the incidence of traffic accidents is also on the rise. At present, the protective devices on both sides of the expressway are mainly composed of columns and guardrails on their tops. The guardrails are made of steel plates, and both the columns and the guardrails are rigid materials. At present, the existing guardrails on the market do not have the function of cushioning and shock absorption when they are in use. When a car hits the guardrail, it can only rely on the deformation of the guardrail to damage the energy absorption, and the deformation and energy absorption capabilities are limited. And the guardrail board is easy to break under the impact of the automobile, causing th...

Problems solved by technology

[0004] In order to solve the above-mentioned existing technical problems, the present invention provides a highway anti-collision device, mainly for the purpose of developing an anti-collision device with an anti-collision buffer unit. Absorbing the impact force of the out-of-control vehicle can reduce the damage to the vehicle during the collision process and can effectively prevent the car body and crew from being injured by the damaged rigid guardrail, which can effectively improve the safety performance of the highway guardrail and avoid excessive collision prevention structures. Problems such as deformation and damage occur
