[0002] Steel rail is the main component of railway track. Its function is to guide the wheels of locomotives and vehicles to advance, bear the huge pressure of the wheels, and transfer it to the sleepers. When the track locking rail temperature does not meet the technical requirements, rail stress relief operation needs to be carried out on the track. The stress relief of the steel rail requires the placement of a roller between the bottom of the steel rail and the sleeper, so that the steel rail is released from the constraint of the sleeper and is in a completely free state. When small size horizontal errors occur on the upper surface of the railway track, different thickness of shims need to be placed between the bottom of the steel rail and the sleeper to ensure the size requirements and operation quality of the small size horizontal adjustment operation. During these operations, the lifting of the steel rail needs to be carried out.

[0003] Patent No. CN221501605U discloses a steel rail lifter. The steel rail lifter operates a No. 1 motor to make the lifting belt run, the lifting belt drives the sliding frame to slide on the main frame, realizes the lifting of the insertion rod, and adjusts the left and right positions of the insertion rod by operating a No. 2 motor to make the threaded rod rotate. A No. 3 motor is operated to make the connecting belt run, so that the insertion rod moves forward and backward, realizes the lifting of the steel rail and the accurate placement of the position, and is convenient to use. In addition, four groups of side plates are fixed with fixed seats, the fixed seats are installed with hydraulic rods, the hydraulic rods rotate on the fixed seats, and the side plates are installed with arm rods, the arm rods are installed on the side plates through pins, the extension ends of the hydraulic rods are connected with the arm rods through pins, the arm rods are installed with bottom plates, the bottom plates are provided with anti-skid groove structures.
