The invention relates to the technical field of track maintenance and replacement, in particular to a track hoisting and replacing device which comprises a hoisting assembly, a lifting assembly, a lifting assembly and a lifting assembly, and the hoisting assembly comprises a bearing column, a containing cavity formed in the bearing column and a supporting column arranged on the outer wall of the bearing column; the telescopic assembly comprises a connecting piece, and a movable piece is arranged at the end of the connecting piece. The supporting assembly comprises a pushing piece, and a control piece and a locking piece arranged on the outer wall of the pushing piece are arranged in the containing cavity; a pushing block is arranged, a movable piece is driven to move downwards, the movable block makes contact with the ground downwards, the movable block makes contact with the uneven ground downwards through a first elastic piece, meanwhile, the pushing block moves downwards on a bearing column, a movable block in a supporting block is driven to extend outwards to make contact with the ground, and the contact area with the ground is increased; and after the rail lifting device is used, the two rail lifting devices are drawn close, and meanwhile, the use space of the rail lifting device is also saved.
本发明涉及轨道检修及更换技术领域,特别是一种轨道起吊更换装置,其包括起吊组件,包括有承重柱、设置于承重柱内部的容置腔和设置于承重柱外壁的支撑柱;以及,伸缩组件,包括有连接件,连接件端部设置有活动件;以及,支撑组件,包括推动件、容置腔内部设置有控制件和设置于推动件外壁的锁止件;本发明通过设置推动块,带动活动件向下运动,活动块向下接触到地面,依靠第一弹性件,使活动块向下接触凹凸不平的地面,同时推动块在承重柱上向下运动,带动支撑块内部的移动块向外伸出,与地面接触,增大与地面的接触面积,提升轨道起吊装置的平稳性,当使用结束之后,将两幅轨道起吊装置靠拢即可,同时也节省了装置的使用空间。
