Steel rail lifting device

The invention relates to a steel rail lifting device. The steel rail lifting device is composed of suspending connecting steel plates, bolts and a beam. A suspension loop is welded to the middle of the beam, steel pipe rings are welded to the two ends of the beam, the suspending connecting steel plates are mounted on the suspension loop and connected together in a penetrating mode through the bolts, and hook corners are arranged at the bottoms of the suspending connecting steel plates and used for clamping a steel rail. In the rail weighbridge standard height adjusting operation, the rail lifting clamping device is used for adjusting the standard height of a fixed road bed steel rail, the lifting height can be increased by 180 mm at a time, and thus working efficiency of steel rail standard height adjustment by additionally mounting or dismounting spacers is improved by one or more times than the original efficiency; mechanical jacks have good self-locking performance, and the steel pipe rings are welded to t
