Emergency repair pier based on telescopic pier body
The first-aid repair pier comprises N sections of tubular pier bodies, N is a positive integer larger than or equal to 2, and the upper section of pier body is sleeved with the next section of pier body adjacent to the upper section of pier body; the lifting driving mechanism is used for driving the pier bodies above the first section of pier body to vertically lift so as to realize expansion and contraction of the first-aid repair pier; a limiting guide mechanism used for telescopic movement and a positioning connection mechanism used for fixedly connecting the previous pier body with the next pier body after the previous pier body is lifted to a preset position are arranged between every two adjacent pier bodies. The technical problem that the existing railway rush-repair bridge pier assembling and erecting speed is low is solved, and meanwhile the traffic speed of a rush-repair bridge is increased.
本发明涉及一种基于可伸缩墩身的抢修桥墩，N节管状墩身，N为大于等于2的正整数，上一节墩身套装在与之相邻的下一节墩身内；升降驱动机构，用于驱动第一节墩身以上的墩身垂直升降以实现抢修桥墩伸缩；相邻的两节墩身之间设置有用于伸缩运动的限位导向机构，及用于使上一节墩身在升起至预设位置后与下一节墩身固定连接的定位连接机构。本发明解决了既有铁路抢修桥墩拼组架设速度慢的技术问题，同时提高被抢修桥梁的通车速度。
