Anti-collision guardrail
The invention discloses an anti-collision guardrail and relates to the field of road guardrails. The problem that when friction occurs between an existing guardrail and a front bumper of an automobile, in-situ rotation or rollover and other phenomena are prone to occurring is solved. The anti-collision device comprises the stand columns, the corrugated plates and the rotating bodies, the multiple stand columns are arranged in parallel at intervals, the corrugated plates are installed on the multiple stand columns, the multiple rotating bodies are rotatably installed on the corrugated plates and/or the stand columns, when an automobile collides with the corrugated plates, the corrugated plates firstly stretch under the collision of the automobile, the kinetic energy of the automobile can be absorbed in the process, and the kinetic energy of the automobile can be absorbed; in the energy absorption stage, the automobile continuously moves to be in contact with the rotating body, and in the guiding stage, sliding friction force generated by the automobile and the corrugated plate is changed into rolling friction force, and the rolling friction coefficient is far smaller than the sliding friction coefficient, so that the friction force between the automobile and the guardrail is reduced, the automobile is stressed more uniformly, and the automobile can continuously move along the guardrail; and the phenomenon of in-situ rotation or rollover is avoided.
一种防撞护栏，涉及道路护栏领域。为解决现有的护栏与汽车前保险杠发生摩擦时容易发生原地打转或侧翻等现象的问题。本发明包括立柱、波纹板和转动体，立柱具有平行间隔设置的多个，波纹板安装在多个立柱上，转动体具有转动安装在波纹板和/或立柱上的多个，当汽车与波纹板发生碰撞时，波纹板首先在汽车的撞击下进行舒展，此过程会吸收汽车的动能，为吸能阶段，汽车继续移动则会与转动体接触，为导向阶段，汽车与波纹板产生的滑动摩擦力变为了滚动摩擦力，滚动摩擦系数远远小于滑动摩擦系数，因此，汽车与护栏之间摩擦力减小，汽车受力更加均匀，能够沿着护栏继续移动，避免发生原地打转或侧翻的现象。
