Pier anti-collision device with sliding guiding and multiple energy dissipation functions
The invention relates to the technical field of pier collision prevention, in particular to a sliding-guiding multiple-energy-consumption pier collision prevention device. Comprising a pier, a rolling track is arranged in the circumferential direction of the pier, a first protection device is arranged on the outer side of the pier, a rolling groove is formed in the first protection device, a rolling body is arranged between the rolling groove and the rolling track, second protection devices are arranged on the upper side and the lower side of the first protection device correspondingly, and sliding grooves are formed in the second protection devices; the pier is provided with a sliding rail, and the first protection device is connected with the second protection device through a damping block. By arranging the first protection device and the second protection device, when the pier is impacted by a vehicle, the first protection device and the second protection device deform plastically to achieve energy consumption of impact force; the first protection device and the second protection device rotate relative to the bridge pier, and impact force transmitted to the bridge pier can be greatly reduced; relative movement between the first protection device and the second protection device drives the damping block to shear and deform to further consume energy, and the destructive effect of the vehicle on the pier is reduced.
本发明涉及桥墩防撞技术领域，具体为一种滑动导向多重耗能的桥墩防撞装置。包括桥墩，桥墩的周向设置有滚动轨道，桥墩的外侧设置有第一防护装置，第一防护装置上设置有滚动槽，滚动槽与滚动轨道之间设置有滚动体，第一防护装置的上下两侧分别设置有第二防护装置，第二防护装置上设置有滑动槽，桥墩设置有滑动轨道，第一防护装置通过阻尼块与第二防护装置连接。本发明通过设置第一、第二防护装置，在桥墩受到车辆冲击时，第一、第二防护装置塑性变形实现冲击力的耗能；第一、第二防护装置相对于桥墩转动，还能大幅削减传递到桥墩的冲击力；第一、第二防护装置之间的相对运动，带动阻尼块剪切变形进一步耗能，降低车辆对桥墩的破坏作用。
