A buffer crash barrier

Abstract

The invention discloses a buffer and anti-collision guardrail, which comprises an upper beam, a lower beam, a column, and a buffer protection plate; the upper beam and the lower beam are parallel to each other, and both the upper beam and the lower beam are vertically fixed on the column; the buffer protection plate The upper end of the buffer protection plate is snapped into the upper beam, and the lower end of the buffer protection plate is clamped into the lower beam. Both the upper beam and the lower beam are provided with guide rails for the buffer protection plate to slide. The guide rails are along the axis of the upper beam and the lower beam. Horizontal grooves arranged in the direction, longitudinal grooves are evenly arranged on the guide rail, the longitudinal grooves are arranged perpendicular to the axis direction of the guide rail, and the opening direction of the longitudinal groove is upward; multiple buffer limiters are uniformly arranged on the guide rail, buffer protection The plate slides along the guide rail between multiple buffer limiters; the buffer crash barrier uses various components to cooperate with each other to buffer the impact force of the accident vehicle hitting the guardrail, and the buffer braking distance and time of the accident vehicle are extended, thereby reducing personnel Damage received during the collision.

Description

technical field [0001] The invention relates to the technical field of traffic equipment, in particular to a buffer and anti-collision guardrail. Background technique [0002] Highway anti-collision guardrails are protective facilities installed on both sides of the road and the central divider, etc., to slow down the impact of vehicles in the event of an accident, prevent vehicles from rushing out of the road range, and protect people and vehicles. [0003] Highway anti-collision guardrails can usually be divided into rigid guardrails, flexible guardrails and semi-rigid guardrails according to the degree of deformation after collision. Among them, semi-rigid guardrails are widely used as roadside guardrails of expressways in my country. For example, more wave plate guardrails are currently used. It can absorb energy through the plastic deformation of vehicles, guardrail corrugated plates, beams and columns during impact, reduce the injury and damage of personnel and vehicles...

AI Technical Summary

Problems solved by technology

However, when a traffic accident occurs, only relying on the plastic deformation of the corrugated plate and the anti-blocking block can play a limited role in buffering and protection, and often cannot protect people and vehicles well. When a vehicle collides with the guardrail on the highway , still vulnerable to greater injuries, especially in accident-prone areas, it is necessary to use guardrails with better buffering effects to block vehicles in accidents and avoid them from rushing out of the road while reducing injuries to personnel
