The invention belongs to the technical field of mechanical equipment maintenance, and particularly relates to a steam turbine rotor lifting device and a lifting method. According to the invention, the whole body of the lifting beam lifting point penetrates through the lifting beam main body, is welded with the middle position of the lifting beam main body, and is a lifting point of the lifting device; the hanging beam hanging belts are hung on the hanging beam body through the sliding saddles and distributed on the two sides of the hanging beam body in a central symmetry mode, and the sliding saddles can slide on the hanging beam body. The steam turbine rotor hanging belt is connected with the hanging beam hanging belt; the steam turbine rotor hanging belt is sleeved on a steam turbine rotor; the sleeve is fastened on the lifting beam lifting lug, the pin shaft is installed in the sleeve, a thread is arranged in the center of the pin shaft, the pin shaft is connected with the screw rod in a matched mode and used for connecting the lifting beam lifting lug with a crane lifting hook, and the pulley A is fastened on the screw rod and integrated with the screw rod. And the crane lifting hook, the lifting beam and the lifting point form a lifting device bearing point. The lifting device is simple in structure, easy to operate, convenient to maintain, high in universality and capable of being used for lifting any similar rotor parts within the rated load of the lifting beam.
