Multi-directional protection self-resetting bridge pier anti-collision structure
The invention provides a multi-directional protection self-resetting bridge pier anti-collision structure, and belongs to the technical field of bridge pier anti-collision. Comprising a bidirectional rotation anti-collision assembly, a multidirectional anti-collision unloading assembly and an internal force adjusting assembly. The whole body is fixedly connected with a bridge pier main body through an elastic buffer connecting assembly, a plurality of groups of main anti-collision blocks are uniformly and rotationally arranged on the outer surface of an outer fixing ring through main anti-collision block supporting plates and rotating inner blocks, and upper jacking springs and lower jacking springs are arranged between the two sides of the two groups of main anti-collision block supporting plates which are symmetrically distributed left and right and the outer fixing ring. An inner elastic piece is further connected between the upper jacking spring and the lower jacking spring which are symmetrically distributed in the left-right direction and the inner surface of the main anti-collision block, multiple elastic supporting on the main anti-collision block can be achieved through the upper jacking spring, the lower jacking spring and the inner elastic piece, and therefore multiple elastic buffering force is formed. The elastic supporting force of the upper jacking spring and the lower jacking spring can be adjusted by screwing the upper jacking column and the lower jacking column, and the elastic supporting force of the adjusting compression spring on the inner elastic piece can be adjusted by screwing the adjusting hexagon.
本发明提供一种多向防护的自复位桥梁桥墩防撞结构，属于桥梁桥墩防撞技术领域。包括双向旋转防撞组件、多向防撞卸力组件、内力调节组件；整体通过弹性缓冲连接组件与桥墩主体固定连接，数组主防撞块通过主防撞块支撑板与旋转内块均匀的旋设在外固定圈的外表面，左右对称分布的两组主防撞块支撑板的两侧与外固定圈之间都设有上顶簧与下顶簧，且左右对称分布的上顶簧与下顶簧与主防撞块的内表面之间还连接有内弹片，通过上顶簧、下顶簧和内弹片可实现对主防撞块多重的弹性支撑，从而形成多重的弹性缓冲力；通过旋拧上顶柱与下顶柱可对上顶簧与下顶簧弹性支撑力的大小进行调节，通过旋拧调节六方可对调节压簧对内弹片的弹性支撑力的大小进行调节。
