Steel structure guardrail type folding highway access road with emergency evacuation function

Abstract

A steel structure guardrail type folding highway access road with an emergency evacuation function comprises an access road main body, a vertical rotating shaft outrigger, foldable outriggers and slope extending plates, wherein the vertical rotating shaft outrigger is positioned at the middle part of the access road main body; the foldable outriggers are hinged under the two ends of a guardrail cross frame; slope extending plates are hinged at two ends of the access road main body; the slope extending plates are positioned at the upper part of the access road main body after being folded and obliquely extend downwards at the end parts of the access road main body to form slopes after being unfolded; the upper part of the access road main body is a steel structure panel; two sliding rods, which are parallel to a length direction of the access road main body, are respectively arranged in positions under the steel structure panel and close to the two side edges of the steel structure panel; slope climbing plate devices are mounted on the sliding rods; the widths of the slope climbing plate devices are larger than or equal to that of a lane; and after the upper ends of the retracted slope climbing plate devices rotate around the sliding rods, the slope climbing plate devices can be accommodated under the access road main body. When traffic jams are caused due to highway accidents, the access road can be unfolded in time to rapidly evacuate traffic jams and open traffic jam knots.

Description

technical field [0001] The invention mainly relates to the technical field of expressway traffic jam emergency treatment, in particular to an expressway steel structure guardrail type folding sidewalk with emergency evacuation function. Background technique [0002] With the rapid development of the national economy, my country's expressways have developed more generally. The structure of domestic expressways is a one-way passage formed by isolation through guardrails. Once a major accident occurs, it is basically blocked. Due to the low quality of the people , the emergency passages reserved on the side of the expressway are often blocked, and it is troublesome for rescue vehicles and personnel to enter the accident scene. waiting for solution. Contents of the invention [0003] In order to improve and solve the above-mentioned problems, the present invention proposes a guardrail type folding sidewalk with steel structure of expressway with emergency evacuation function. ...
