Road and bridge protective fence
The invention relates to the technical field of guardrails, and discloses a road and bridge guardrail which comprises an upper channel steel plate, a lower channel steel plate and shaft seats, the inner sides of the upper channel steel plate and the lower channel steel plate are slidably connected with the shaft seats, bearings are installed in the shaft seats, roller assemblies are rotatably connected in the bearings, buffer assemblies are installed on the outer surfaces of the shaft seats, and one ends of the buffer assemblies are connected with sliding blocks. The two sides of the sliding block are fixedly connected with sliding rods, and the buffering assembly comprises a pressing rod, a piston, a sleeve, an outer spring, a fixing block, an inner push rod, a push piece and an inner spring. According to the road and bridge protective fence, by arranging the roller assembly, when an automobile accidentally collides with the protective fence, the automobile can make contact with a roller body, and due to the fact that the roller body is cylindrical in appearance, the roller body can rotate around a rotating rod under the action of automobile impact force; in this way, most of impact force instantly generated by the automobile can be converted into rotating force, and therefore damage to the protective fence and the automobile caused by the impact force of the automobile can be reduced.
本发明涉及防护栏技术领域,且公开了一种道路桥梁防护栏,包括上槽钢板、下槽钢板和轴座,上槽钢板和下槽钢板的内侧均滑动连接轴座,轴座内安装轴承,轴承内转动连接滚筒组件,轴座的外表面安装缓冲组件,缓冲组件的一端连接滑动块,滑动块的两侧固定连接滑杆,缓冲组件包括压杆、活塞、套筒、外弹簧、固定块、内推杆、推片和内弹簧。本发明提供的一种道路桥梁防护栏,通过设置滚筒组件,当汽车意外撞击到防护栏上后会接触到滚筒本体,由于滚筒本体外形上呈圆柱形,在汽车冲击力的作用下滚筒本体会围绕转杆发生自转,如此能将汽车瞬时产生的冲击力大部分转化为旋转力,如此能减小汽车冲击力对防护栏以及汽车本身造成的伤害。
