The invention discloses a novel hydraulic track jack for laying a railway track, which relates to the technical field of hydraulic track jacks. The flexibility of track lifting is improved. The device specifically comprises a base, first sliding grooves are formed in the inner walls of the two sides of the base correspondingly, two sliding way frames are slidably connected to the inner walls of the two first sliding grooves correspondingly, connecting columns are fixed to the inner walls of the two sliding way frames through screws correspondingly, adjusting screw rods are rotationally connected to the inner walls of the other two sliding way frames correspondingly, the inner walls of the two sliding way frames located on the two sides are slidably connected with the same lifting frame, the inner walls of the two sides of the lifting frame are fixedly provided with the same sleeve rod through screws, the circumferential outer walls of the sliding way frames are slidably connected with two sliding frames, the outer walls of the bottoms of the two sliding frames are fixedly provided with clamping plates through screws, and the inner walls of the two sliding frames are rotationally connected with adjusting rods. By arranging the second hydraulic cylinder, the sleeve can be driven to move upwards, and due to the limiting effect of the limiting base, the sleeve can drive the jacking column to move upwards in the upward moving process.
本发明公开了一种铁路轨道铺设用的新型液压起道器，涉及液压起道器技术领域；为了提高起道的灵活性；具体包括底座，所述底座两侧内壁均开设有滑槽一，两个滑槽一内壁均滑动连接有两个滑道架，其中两个所述滑道架内壁均通过螺丝固定有连接柱，另外两个所述滑道架内壁均转动连接有调节螺杆，位于两侧的两个滑道架内壁滑动连接有同一个升降架，所述升降架两侧内壁通过螺丝固定有同一个套杆，所述滑道架圆周外壁滑动连接有两个滑动架，两个所述滑动架底部外壁均通过螺丝固定有夹持板，两个所述滑动架内壁均转动连接有调节杆。本发明通过设置有液压缸二可以带动套筒上移，由于限位座的限位作用，套筒在上移的过程中可以带动顶柱上移。
