Road separation anti-collision guardrail

Abstract

The invention provides a road separation anti-collision guardrail which comprises a base, a switching mechanism is arranged on the outer surface of the upper end of the base, a guardrail body is arranged on the outer surface of the upper end of the switching mechanism, a supporting plate is arranged between the guardrail body and the base, and a collecting mechanism is arranged on the outer surface of the left side of the base. A cleaning mechanism is arranged on the outer surface of the right side of the base. The conversion mechanism comprises an arc-shaped groove, an arc-shaped plate, a limiting groove, a first movable groove, a supporting frame, a supporting plate, a groove, a steel ball, a second movable groove, a spring air bag, a movable block, a limiting cavity, a first movable rod, a second movable rod, an inserting groove and a first storage bag, the arc-shaped groove is formed in the outer surface of the lower end of the guardrail, and the arc-shaped plate is rotationally connected into the arc-shaped groove. According to the device, when the guardrail is impacted by external force of a vehicle, the damaged front rod and the intact rear rod are rotated, switched in position and fixed again, and meanwhile the purposes of warning rear vehicles and conducting auxiliary supporting and fixing on the rear rod again can be achieved.

Description

technical field [0001] The invention relates to the technical field of guardrails, in particular to a road separation crash guardrail. Background technique [0002] Highway anti-collision guardrail is the most important traffic infrastructure. my country's expressway was developed in the 1980s and is an important maintenance and safety guarantee facility for expressways. [0003] The existing patent (notification number: CN108867468B) is a safety guardrail applied to mountainous roads, including: a frame body, the bottom of which has a number of first fixing columns for inserting into the ground, and the front and rear of the frame body are provided with two The accommodating cavity arranged vertically up and down forms the upper beam, the middle beam and the lower beam arranged from top to bottom; several buffer components are arranged in an array and installed in the frame body, and each buffer component includes a The upper buffer, the first rotating shaft, the middle bu...

AI Technical Summary

Problems solved by technology

[0005] 1. In some mountainous areas in northwestern my country, there are many curves on the mountain roads, and it is very easy to collide with the railings. However, due to the large dust on the ground, rugged mountain roads, and mountain shelters, even if an accident occurs, the rear vehicles cannot be observed. And detour in time, thus causing traffic jams, and at the same time, the collision of the guardrail in the mountainous area cannot be quickly detected by the maintenance personnel and the damaged part will be repaired, which will cause certain safety hazards for the subsequent vehicles;

[0006] 2. In the arid mountainous road section in the northwest, the road surface is dusty, which is not convenient for users to survey the road conditions. At the same time, there is little rain in the arid area, which leads to the death of a large number of mountainous trees, resulting in desertification of green forests. Traditional anti-collision guardrails cannot collect rainwater. Sprinkling water on the road surface reduces dust and waters trees, thereby reducing the efficiency of the device
