The invention relates to a hydraulic track jack and a using method thereof, and relates to the technical field of railway track laying and maintenance, the hydraulic track jack comprises a handle rod,a lifting handle, a reset spring, an oil return valve, a piston, an oil cylinder, a limiting nut, a locking nut, an adjusting screw rod, a hydraulic power unit, a rack and the like; two rack hook parts that can be in contact with a steel rail and apply upward acting forces to the rail jaws are arranged at the rack; hydraulic track jack rotates along the vertical axis of the steel rail, the rack hook parts can enter a contact state from a state of being separated from the rail jaw, the purpose of separating and clamping the rail head is achieved without opening and closing, the rack is an integral body, the stress structure is more reasonable, the strength is higher, and the operation is more convenient and faster.
本发明涉及一种液压起道器及其使用方法，涉及铁路轨道的铺设和维护技术领域，包括手柄杆、提把、复位弹簧、回油阀、活塞、油缸、限位螺母、锁紧螺母、调整螺杆、液压动力单元、机架等部分组成，机架设有两处可与钢轨的轨颚接触，并对轨颚施加向上作用力的机架钩部，通过对液压起道器沿钢轨竖轴进行旋转，机架钩部可从与轨颚脱离状态进入到接触状态，不需要通过开、合方式来达到脱离、卡住轨头的目的，机架为一个整体，受力结构更合理，强度更高，操作更便捷。
