Jacking device for motor assembly

The invention discloses a jacking device for motor assembly, the device comprises a supporting seat, a rotor base plate, a screw rod mechanism, a turbine worm mechanism, a driving mechanism, a control system and trundles are installed on the supporting seat, the rotor base plate is installed on the upper end face of the screw rod mechanism and is used for placing a rotor, the screw rod mechanism is connected with the turbine worm mechanism, and the turbine worm mechanism is connected with the driving mechanism. The worm and gear mechanism is connected with the driving mechanism, the control system is in communication connection with the driving mechanism, and the control system controls the driving mechanism through an instruction so as to drive the worm and gear mechanism to drive the lead screw mechanism to perform lifting linkage; the supporting base moves through the trundles. According to the invention, the turbine worm and the screw rod structure are driven to cooperate with different gears, the rotor i
