Weight lifting device for power distribution substation construction

The heavy object lifting device for the power distribution substation construction comprises a bottom plate, a third electric push rod and a rotating shaft, the outer surface of the rotating shaft is fixedly connected with a half gear, one side of the half gear is fixedly connected with a supporting arm, and the other side of the supporting arm is fixedly connected with a stabilizing plate. The extending end of the third electric push rod is fixedly connected with a movable plate, and the left end and the right end of the top of the movable plate are both fixedly connected with toothed plates. Through the action of the toothed plate, the supporting arm, the stabilizing plate, the chain, the guide chain wheel base, the first electric push rod, the second electric push rod, a half gear, a moving wheel, a third electric push rod, a movable plate, a moving plate and a Z-shaped fixing plate, the problem that an existing weight lifting device is insufficient in stability in the using process and prone to toppling o
