The invention provides a conical pipe fitting lifting appliance, and belongs to the technical field of lifting appliances for lifting pipes, the lifting appliance is characterized in that a connecting disc is provided with at least three lower support arms, the lower ends of the lower support arms are hinged with swing rods, and the front ends of the swing rods are hinged with pressing blocks. The pull rod vertically penetrates through the middle of the connecting disc and is provided with a disc and a positioning disc from bottom to top in sequence. The upper section of the pull rod is sleeved with the sliding frame, a pressure spring is arranged between the lower portion of the sliding frame and the upper portion of the positioning disc, cantilevers corresponding to the swing rods are arranged on the sliding frame along the circumference, and the tail ends of the cantilevers are connected with the rear ends of the swing rods through inhaul cables. The inner supporting plate is arranged between the lower supporting arm and the pull rod, the upper end of the inner supporting plate is hinged to the connecting disc, the hinge axis of the inner supporting plate, the hinge axis of the pressing block and the hinge axis of the swing rod are all perpendicular to the shaft of the connecting disc, and the distance between the hinge axis of the inner supporting plate and the axis of the pull rod is smaller than the radius of the disc. According to the scheme, hoisting can be directly conducted from the top end of the conical pipe, the purpose of automatic unlocking can be easily achieved, and operation is simpler and safer.
