Highway automobile anti-collision device

Abstract

The invention discloses a highway automobile anti-collision device which comprises two sets of supporting frames which are symmetrically arranged up and down and a plurality of anti-collision barrels installed between the two sets of supporting frames, and the two sets of supporting frames are installed on the road surface through supporting stand columns; the supporting frame comprises two supporting rods which are symmetrically arranged inside and outside and extend in the longitudinal direction and a connecting frame which is fixed between the two supporting rods in a spaced mode, a sliding groove which obliquely extends outwards and forwards is formed in the connecting frame, a sliding block is installed in the sliding groove in a sliding mode, and a spring is supported between the sliding block and the outer front end of the sliding groove; and each anti-collision barrel is rotationally mounted between two sliding blocks which are symmetrically arranged up and down through a rotating shaft. According to the highway automobile anti-collision device, the automobile can be effectively buffered and slowed down when the automobile obliquely collides with the protective fence, so that the aim of protecting the collision safety of the automobile is fulfilled.

Description

technical field [0001] The invention relates to the technical field of highway safety protection, in particular to a vehicle anti-collision device for highways. Background technique [0002] Highway anti-collision barriers are important maintenance and safety facilities for expressways. The traditional high-speed anti-collision barriers are the main form of semi-rigid barriers. It is a continuous structure that is spliced ​​with corrugated steel guardrails and supported by main columns. , it mainly uses the deformation of the soil foundation, supporting columns, and beams to absorb the collision energy, and forces the out-of-control vehicle to change direction and return to the normal driving direction, preventing the vehicle from rushing out of the road, so as to protect the vehicle and passengers and reduce the loss caused by the accident . [0003] The rotating barrel type anti-collision barrier is a new type of anti-collision barrier. For the traditional anti-collision ...

Problems solved by technology

[0005] However, most of the time when the car is running, it crashes into the guardrail obliquely. Although the former structure can buffer the rotating bucket in the horizontal direction, the sub-velocity of the car is mainly in the longitudinal direction, and its buffering effect on the car is poor. , and the guardrail is easy to be bumped and deformed. Although the latter structure can buffer the rotating bucket in the longitudinal direction, there is a component velocity in the lateral direction when the car crashes into the guardrail obliquely. was ejected causing the vehicle to roll over
