Anti-collision design structure for emergency escape lane of expressway

Abstract

The invention provides an anti-collision design structure of a highway emergency escape lane. The anti-collision design structure comprises a front breast board, a rear breast board, side breast boards, a base, a buffer frame, a buffer sleeve, a damping column, rubber tires, a fastening rope and a spring. Side fixing frames are fixedly connected to the two sides of the front breast board respectively; the two sides of the rear breast board are fixedly connected to the side fixing frames on the two sides through bolts. The side face of the base is fixedly connected with the lower portion of the outer wall of a side fixing frame. The lower ends of the side breast boards are movably connected to the edge of the upper surface of the base through hinges; the lower end of the buffer sleeve is connected to the outer side of the upper surface of the base through welding; after being impacted, the breast boards can be deformed and unfolded for a certain length, the further buffering effect is achieved, compared with a commonly-used buffering facility for stacking tires in a traditional emergency lane, the safety is improved, and the situation that safety accidents happen due to the fact that a vehicle is out of control and collides with the side edge of the emergency emergency lane can be avoided through the arrangement of the side edge damping devices; and the buffering effect from the side face is achieved.

Description

technical field [0001] The invention belongs to the technical field of anti-collision equipment for avoidance lanes, and more specifically relates to an anti-collision design structure for expressway emergency escape lanes. Background technique [0002] The avoidance lane is a "life-saving road", which connects the main lane and makes a fork of the main lane. Its main function is that the continuous use of the brakes after the vehicle enters the downhill section will easily cause the brake hub to overheat, resulting in reduced braking performance or brake failure. , And the vicious traffic accidents of rear-end collision, collision and car crash down the cliff occurred. In order to eliminate potential safety hazards as soon as possible, a transitional section of the approach road (intersecting with the main lane) is set up to allow the driver to turn the car to the transition section of the approach road (such as a slope about 50-100 meters long, and the lane is paved with a...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides an anti-collision design structure for the emergency avoidance lane of the expressway, so as to solve the problem that the buffering effect of the safety guardrail of the escape lane in the above-mentioned patent is small, and the safety performance is low. It is easy to collide with the side of the avoidance lane. Due to the lack of protection facilities and shock absorption equipment on the side of the lane, the vehicle colliding with the side of the emergency lane is likely to cause serious damage to the vehicle or damage the lane guardrail.
