Hydraulic steel rail stretcher
The invention belongs to the technical field of rail traffic equipment, and discloses a hydraulic steel rail stretcher which comprises hydraulic telescopic rods, electromagnetic control valves are fixedly mounted on the left sides and the right sides of the tops of the two hydraulic telescopic rods, rectangular protrusions are slidably mounted at the right ends of the hydraulic telescopic rods, and fixing pins movably sleeve the middles of the rectangular protrusions. A metal conductive shaft is adjusted to a target scale position needing to move, then a threaded rotary knob is screwed to fix the metal conductive shaft, a left sliding piece and a right sliding piece are adjusted to be attached to the cross section of a steel rail, a right binding post and a left binding post are connected with an electromagnetic control valve through wires, and a hydraulic telescopic rod is controlled to move the steel rail; when the metal conductive shaft is in contact with the contact seat, the electromagnetic control valve is closed, so that the hydraulic telescopic rod is stopped from shortening, the distance between the two steel rails is adjusted to the target distance at a time, and the problems that when the existing steel rails are adjusted to the target distance, multiple times of adjustment are needed, and the working efficiency is reduced are solved.
本发明属于轨道交通设备技术领域，且公开了一种液压钢轨拉伸器，包括液压伸缩杆,两个液压伸缩杆顶部的左右两侧均固定安装有电磁控制阀，液压伸缩杆的右端滑动安装有矩形凸起，矩形凸起的中部活动套接有固定销。本发明通过调节金属导电轴至需要移动的目标刻度处，再旋紧螺纹旋钮将金属导电轴固定，调节左滑动片和右滑动片与钢轨的横截面贴合，右接线柱、左接线柱通过导线与电磁控制阀连接，控制液压伸缩杆将钢轨进行移动，当金属导电轴与接触座接触时，会使电磁控制阀关闭，从而停止液压伸缩杆缩短，从而一次将两条钢轨之间的距离调节至目标间距，解决了现有钢轨在调节至目标间距时，需多次调整，降低工作效率的问题。
