The invention discloses a large rail piece laying and replacing operation method. A first transport flatcar, a second transport flatcar and a rail car are grouped and coupled to run to a designated position of a replacing operation site. And the portal crane devices are clamped and turned over one by one through the retracting and releasing device, and meanwhile, the portal crane devices are unloaded from the first transport flatcar according to the position and sequence after being restored to the unfolded state and placed at the designated position. And unloading the new large rail piece from the second transport flatcar through a group crane consisting of a plurality of gantry crane devices, placing the new large rail piece on one side of a line below the gantry crane devices, hoisting the disassembled old large rail piece to the other side, and hoisting the new large rail piece to the position of the original old large rail piece on the line, thereby completing the replacement of the new large rail piece and the old large rail piece. And after the line is recovered, the old rail large rail piece and the gantry crane device are recovered according to the same method, and the first transportation flatcar and the second transportation flatcar are driven away from the rail car marshalling. The technical problems that an existing large rail part replacing device is complex in structure and operation, high in cost and limited in space utilization can be solved.

    本申请公开了一种轨道大轨件铺换作业方法,第一、第二运输平车与轨道车编组连挂行驶至更换作业现场的指定位置。通过收放装置将门吊装置逐个夹持、翻转,同时门吊装置恢复展开状态后按位置和顺序从第一运输平车上卸下,并放置于指定位置。通过由多个门吊装置组成的群吊将新轨道大轨件从第二运输平车上卸载并放置于门吊装置下方的线路一侧,将拆卸的旧轨道大轨件吊装至另一侧,再将新轨道大轨件吊装至线路上原旧轨道大轨件的位置,完成新旧轨道大轨件的更换。待线路恢复后,按照同样的方法回收旧轨道大轨件及门吊装置,第一、第二运输平车与轨道车编组驶离。本申请能解决现有轨道大轨件更换设备结构和操作复杂,成本较高,空间利用受限的技术问题。
