Steel rail stretcher for laying subway track
The invention belongs to the technical field of steel rail stretching, and discloses a steel rail stretcher for subway track laying, which comprises an inclined iron seat, pneumatic cylinders are connected to the two sides of the inclined iron seat through bolts, a first notch is formed in the inclined iron seat, a fixing rod is fixedly connected to the interior of the first notch, and a second notch is formed in the interior of the fixing rod. The outer surface of the fixing rod is movably sleeved with first inclined iron and a first spring, a plurality of second notches are formed in the inclined iron base, fixing shafts are fixedly connected into the second notches, the outer surfaces of the fixing shafts are movably sleeved with second springs and connecting plates, and second inclined iron is installed on the outer sides of the connecting plates. The outer surface of the pneumatic cylinder is fixedly sleeved with a fixing ring, the outer side of the fixing ring is movably sleeved with a rotating shaft, the outer surface of the rotating shaft is wound with a plurality of sets of steel wire ropes, and the top end of the rotating shaft is connected with a rocker. And more labor is saved in the mode that kinetic energy generated during operation of the pneumatic cylinder is used for positioning the inclined iron seat.
本发明属于钢轨拉伸技术领域，且公开了一种用于地铁轨道铺设的钢轨拉伸器，包括斜铁座，所述斜铁座的两侧均通过插销连接有气压缸，所述斜铁座的内部开设有第一槽口，所述第一槽口的内部固定连接有固定杆，所述固定杆的外表面活动套接有第一斜铁和第一弹簧，所述斜铁座的内部开设有若干个第二槽口，所述第二槽口的内部固定连接有固定轴，所述固定轴的外表面活动套接有第二弹簧和连接板，所述连接板的外侧安装有第二斜铁，所述气压缸的外表面固定套接有固定环，所述固定环的外侧活动套接有转轴，所述转轴的外表面缠绕有若干组钢丝绳，所述转轴的顶端连接有摇杆。利用气压缸在运行时产生的动能去对斜铁座定位的方式更加的省力。
