Drum-type anti-collision guardrail for offset road
The invention relates to a drum-type anti-collision guardrail for an offset road. The drum-type anti-collision guardrail is characterized in that the drum-type anti-collision guardrail is composed of a protective wall (1) and rolling bodies (2), and the rolling bodies (2) which can roll to unload during collision are installed on the inner side face of the protective wall (1) side by side; the rotating shaft (4) of the rolling body (2) is fixed on the parapet wall (1) through the supporting column (3), and the rotating shaft (4) of the rolling body (2) is movably connected with the rotatable roller column (5). According to the roller type offset road anti-collision guardrail, when an automobile collides, due to the fact that the roller columns slide, the automobile slides forwards along with the roller columns, the yawing effect is achieved, the course of the automobile is guided, the automobile impact momentum and the collision borne by the guardrail are reduced to the maximum degree, the safety coefficient is maximized, and therefore the impact momentum of the automobile on the guardrail is reduced.
本发明涉及一种滚筒式偏移公路防撞护栏。其特征在于滚筒式偏移公路防撞护栏由护墙(1)和滚动本体(2)组成，护墙(1)内侧面上并排安装着撞击会滚动卸力的滚动本体(2)；滚动本体(2)的转轴(4)通过支撑柱(3)固定在护墙(1)上，滚动本体(2)的转轴(4)上活连接着可转动的滚筒柱(5)。本发明一种滚筒式偏移公路防撞护栏，当汽车撞上时，因滚筒柱滑动，汽车随滚筒柱向前滑动，起到偏航的作用，引导汽车航向，最大化减少汽车冲击动量和防护栏本身所受撞击，使得安全系数最大化，从而减轻车辆对护栏间的冲击动量。
