Novel assembly type rotary energy dissipation pier anti-collision device
The invention discloses a novel assembly type rotating energy dissipation bridge pier anti-collision device. A main body structure comprises a rotating layer surrounding the outer side of a bridge pier, a rigid layer, a rotation limiting connecting mechanism and a bottom rail bottom plate. Vertical and transverse pulleys are installed at the bottom and on the side face of the rotating layer correspondingly and matched with the bottom rail bottom plate to rotate around the rigid layer within the limiting range of the limiting rotating connecting device. Low-yield-point steel and high-strength steel are cooperatively used externally to form a thin film effect for deformation energy dissipation, the waste tires and the rigid layer are utilized internally to directly resist impact, and vehicle kinetic energy is fully consumed through rotation of the rotating layer and the rotation limiting mechanism. Effective deformation and rotation energy consumption can be achieved, and the assembly type energy dissipation device is of an assembly type structure and can be rapidly installed and replaced.
本发明公开一种新型装配式转动耗能桥墩防撞装置，主体结构包括围绕在桥墩外侧的转动层、刚性层、限制转动连接机构和底部轨道底板。转动层底部和侧面分别安装有竖向和横向滑轮，配合底部轨道底板在限制转动连接装置限制范围内绕刚性层转动。本发明外部配合使用低屈服点钢材和高强钢材形成薄膜效应进行变形耗能，内部利用废弃轮胎和刚性层反作用力直接抵抗撞击，再通过转动层转动和限制转动机构充分消耗车辆动能。本发明能够实现有效的变形和转动耗能，其为装配式结构可进行快速安装和更换。
