description The utility model relates to a special-shaped casting fixed-distance jacking device which comprises a base, a screw rod and a conical head, the base is in threaded connection with the screw rod, the top of the screw rod is fixedly connected with the conical bottom face of the conical head, the special-shaped casting fixed-distance jacking device further comprises a U-shaped supporting piece, and the U-shaped supporting piece is connected with the conical head through a rotating pair. A rotating shaft of the U-shaped supporting piece and the conical head is an A shaft, and the A shaft, a central shaft of the conical head and a central shaft of the screw are collinear. When the jacking device is used, the U-shaped supporting piece with the groove width larger than that of the grid wall of the grid casting is selected, the grid wall of the grid casting is placed in the groove of the U-shaped supporting piece, the height of the fixed-distance jacking device is adjusted by rotating the screw rod, and then the grid
