Highway anti-collision guardrail

Abstract

The invention belongs to the technical field of guardrails, and particularly relates to a highway anti-collision guardrail which comprises guardrail columns, buffering sleeves, buffering columns, guard plates, coil springs, rotating arms, elastic components and sunscreen sleeves. Stepped holes are formed in two ends of the guardrail columns, the buffering sleeves are detachably arranged in the stepped holes of the guardrail columns, the buffering columns are inserted into the buffering sleeves, arc-shaped ribs are arranged on the curved surfaces of the buffering columns and positioned outsidethe buffering sleeves, the ends of the buffering columns are fixedly connected with the guard plates, the rotating arms are arranged on the guardrail columns in a sleeving manner, the coil springs arearranged among the rotating arms and the guardrail columns and used for increasing rotating resistance of the rotating arms, the elastic components are arranged between the rotating arms on the adjacent guardrail columns, the ends of the elastic components are closely fixed with the rotating arms, the sunscreen sleeves are arranged on the elastic components in a sleeving manner and used for usedfor preventing the elastic components from being exposed to the sun and rain. According to the guardrail, the anti-collision and buffering capability of the highway anti-collision guardrail is improved, the damage extent of a vehicle in accidents is reduced, and casualties are reduced.

Description

technical field [0001] The invention belongs to the technical field of guardrails, in particular to an anti-collision guardrail for highways. Background technique [0002] At present, the protective devices on both sides of the expressway are composed of a column and a protective plate positioned on its upper part. The protective plate is made of a steel plate, and the two are rigid materials and are also rigidly connected. When the car loses control and hits the protective plate, the protective device can prevent the car from turning into the waterproof ditch on both sides of the expressway or rushing into the opposite lane to crash. But practice proves that the protective plate of the above-mentioned structure has no cushioning function, and under the high-speed and powerful impact force of the out-of-control automobile, the car is destroyed and people are killed.

Problems solved by technology

[0004] In the above-mentioned patent document 1, an anti-collision buffer pad composed of a PE outer layer and a PU foam inner layer filled in the PE outer layer is installed on the side of the cement guardrail body close to the inner side of the road; Rollover, bumping car starting cushioning effect, to avoid rigid collision on the cement body to cause damage to the car itself, people inside the car and people or objects outside the car; The anti-collision barrier is designed for the buffering of the tires of the car, but in general, the front of the vehicle hits the barrier first when an accident occurs, so the design of the anti-collision barrier for the buffer wheel will be invalid
