crash barrier

Abstract

The invention provides an anti-collision guardrail. A base is provided with a groove. The bottom of the groove is provided with a first rotating containing groove. An opening of the first rotating containing groove is sequentially connected with a first inclined wall, a side wall and a second inclined wall. The first rotating containing groove is internally provided with a first rotating ball. A vertical column is arranged on the upper portion of the first rotating ball. A second rotating containing groove is formed in the lower end of the vertical column and internally provided with a second rotating ball. The second rotating ball is connected with a supporting rod. The first inclined wall is provided with a sliding groove. The lower end of the supporting rod is placed in the sliding groove, and an inner spring is arranged between the lower end of the supporting rod and the bottom end of the sliding groove. The part, located outside the sliding groove, of the supporting rod is sleeved with an outer spring. The vertical column is internally provided with a steel wire rope stretching device. A plurality of railings are connected between an upper steel wire rope and a lower steel wire rope. Lifting rings are arranged at the two ends of each railing correspondingly. Each lifting ring is internally provided with a buffer layer. Each buffer layer is internally provided with a friction piece. The friction pieces are arranged on the upper steel wire rope or the lower steel wire rope in a sleeving mode. A corrugated anti-collision plate is arranged on the multiple railings. According to the anti-collision guardrail, the collision force of an accident vehicle can be buffered and released, and the impact damage of the guardrail to the accident vehicle and passengers is reduced.

Description

technical field [0001] The invention relates to the technical field of highway guardrails, in particular to an anti-collision guardrail. Background technique [0002] With the continuous development of economic construction, the transportation is increasingly busy. Traffic accidents are currently the most frequent in highway sections or highway bridge sections. In order to reduce the occurrence of traffic accidents, various guardrails are installed on both sides of the road. Since the guardrails are made of inelastic iron structure, the guardrails such as rigid guardrails have strong protective ability, but when the car collides with the guardrail, the Under the action of the instantaneous impact load, the guardrail basically does not move or deform. The energy absorption during the collision process depends on the plastic deformation of the car itself, the frictional contact between the car and the guardrail, and the movement of the car along the The climbing of the guard...
