Buffering device for track protective fence

Abstract

The invention relates to the technical field of track safety protection and discloses a buffering device for a track protective fence. The buffering device for the track protective fence comprises a base; a mounting column is fixedly mounted at the top of the base; a strut is arranged at the top of the mounting column; a reinforcing sheet is fixedly mounted at the top of the mounting column; a shell is arranged on the left side of the strut; a steel wire column is arranged in the shell; and a fixed shell is arranged on the right side of the steel wire column. According to the buffering devicefor the track protective fence, by arranging clamping plates and rollers, the rollers are stressed to rotate in an accelerated manner so as to disperse the impact force of an automobile when the trackprotective fence is collided by the automobile; when the impact force is too large, connecting blocks extrude towards the left, pulleys are stressed to extrude rubber blocks, and the rubber blocks extrude second springs towards the upper and lower sides so that the impact force is further weakened; and when a U-shaped block is stressed, the collision force of the automobile can be more efficiently reduced by using first springs; and therefore, traffic accidents are furthest avoided, and safeties of the automobile and the personnel are greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of rail safety protection, in particular to a buffer device for a rail protection fence. Background technique [0002] With the development of my country's economy, the rail transit is also growing. Both the high-grade rail and the high-speed rail have been greatly developed. The development of the rail provides good conditions for transportation and greatly improves the speed of logistics. , which shortens the material circulation time and increases the speed of vehicles on the road. At present, the protective fence is the most common traffic safety facility in practice, which helps to reduce the occurrence of vehicle accidents and reduce the risk of damage to people and vehicles. Situation happens. [0003] Chinese patent CN 103835248 B proposes a highway guardrail and its preparation method. The guardrail can effectively alleviate the damage caused by the impact of trains and reduce the traffic accidents o...
