Transformer substation hoisting device with adjustable hoisting arm

The invention provides a transformer substation hoisting device with an adjustable hoisting arm. The transformer substation hoisting device comprises a base, a support body, a hoisting arm, a telescopic driving mechanism, a fixed base, a motor, a rotation roller, a hoisting rope, a fixed pulley and a hoisting hook, wherein a top plate is arranged at the top of the support body; the telescopic driving mechanism and the fixed base are fixed on the top plate; a sliding block is arranged in the fixed base; a telescopic part of the telescopic driving mechanism is connected with the sliding block; one end of the hoisting arm is connected with the sliding block; a mounting lug is arranged under the other end of the hoisting arm; the fixed pulley is arranged on the mounting lug; the motor is fixedly connected to the hoisting arm; an output shaft of the motor is connected with the rotation roller through a coupler; one end of the hoisting rope is wound on the rotation roller; the other end of the hoisting rope bypasses the fixed pulley and is connected to the hoisting hook. The transformer substation hoisting device with the adjustable hoisting arm has the advantages that on the one hand, the transformer substation hoisting device has no need to pull the hoisting rope manually, so that the manpower is saved; on the other hand, the length of the hoisting arm can be adjusted according to the mounting position of the device without need to repeatedly adjust the mounting position of the whole hoisting device; the transformer substation hoisting device with the adjustable hoisting arm has strong applicability.
