Hoisting device for transformer substation

The invention provides a hoisting device for a transformer substation. The hoisting device for the transformer substation comprises a base, a support body, a hoisting arm, a motor, a rotation roller, a hoisting rope, a fixed pulley and a hoisting hook, wherein the bottom of the support body is arranged on the base; the hoisting arm is horizontally arranged and is connected to the top of the support body; the motor is arranged at one end, close to the support body, on the hoisting arm; the fixed pulley is arranged at one end, far away from the support body, on the hoisting arm; an output shaft of the motor is connected with a rotation roller through a coupler; one end of the hoisting rope is wound on the rotation roller; the hoisting rope bypasses the fixed pulley and is connected to the hoisting hook. In use, equipment is firstly hoisted on the hoisting hook, then the motor is started; the motor drives the rotation roller to rotate; one end of the hoisting rope is wound on the rotation roller, so that the rotation roller can drive the hoisting hook to move up and down in the rotation process, thereby hoisting new equipment and old equipment. The hoisting device has no need to pull the hoisting rope manually, so that the manpower is greatly saved; the replacement efficiency of the old equipment of the transformer substation is improved.
