By the rotation of the screw handle 113, the cylinder 109 can be moved up and down.

In addition, the upper and lower auxiliary jig weights 114 and 115 are formed by forming upper and lower auxiliary jig weight guide jaws 122 and 123 on the outer side of the cylinder support plate 111, but the upper auxiliary jig weight 114 is an upper auxiliary jig. Produced with the same weight as 106 and connected to the ropes 116 and 116 'to hang on the rope guide roll 117 installed on the frame 104, the lower auxiliary jig weight 115 is the lower auxiliary jig ( 107) is made of the same weight and connected to the rope 116 ″ (116 ′ ″) to be installed on the rope guide roll 117 also installed on the upper frame. The conventional disassembly apparatus 100 configured as described above inserts the workpiece 120 to be disassembled into the insertion hole 105 ′ using a crane or a chain block, and the lower auxiliary jig weight 115 is attached to the lower auxiliary jig 107. Pull down until the center groove (107 ') is in close contact with the workpiece 120, and when stopped in close contact, the weight of the auxiliary jig (107) and the auxiliary jig weight (115) is equal to that position. If the upper auxiliary jig 114 is raised until the groove 106 'of the upper auxiliary jig is brought into close contact with the workpiece 120, the auxiliary jig 106 and the auxiliary jig weight 114 are in close contact with each other. Since the weight is the same, it remains in that position.
