Traction device for steam turbine generator rotor and use method

The invention discloses a turbine generator rotor traction device and a use method, a track is arranged outside a generator shell, a generator rotor carrier loader is placed on the track, and the generator rotor carrier loader is convenient for fixing a generator rotor to be mounted; the generator rotor can be stably borne, adjusted in height and supported in the pulling and penetrating process, the track set supports and restrains the cloud top track of the generator rotor carrier loader, a crane does not need to be used for hoisting in the whole process, and the generator rotor carrier loader can be controlled to move in a set route; the stability of the generator rotor carrier loader in the moving process can be ensured, so that collision between the generator rotor and the generator stator which is easily caused by matching with manual traction under crane hoisting adjustment in the prior art is avoided, and the risk of equipment damage is reduced; according to the device disclosed by the invention, the o
