DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The embodiments of the present utility model will be described in detail below. The embodiments are implemented on the premise of the technical solution of the present utility model, and detailed implementation manners and specific operation processes are given. However, the protection scope of the present utility model is not limited to the following embodiments.

[0018] See Figures 1 to 4, this embodiment discloses a disassembly tool for a wire rope drum. The wire rope drum 1 is tightly fitted with the output shaft 2 of the speed reducer, and the power transmission connection between the two is achieved through a key connection. The disassembly tool includes a connector 3 and a disassembly screw rod 4. Installation studs 5 and positioning holes 6 are respectively provided at both ends of the connector 3. The connector 3 is threadedly connected to the threaded hole at the end of the output shaft 2 of the speed reducer through the installation stud 5. A positioning protrusion 7 is provided at one end of the disassembly screw rod 4, and an external hexagonal operation head 8 is provided at the end of the disassembly screw rod 4 away from the positioning protrusion 7. The positioning protrusion 7 of the disassembly screw rod 4 is in a conical tip shape, and the positioning hole 6 of the connector 3 is a conical hole that matches the positioning protrusion 7. The positioning protrusion 7 of the disassembly screw rod 4 is tightly pressed into the positioning hole 6 of the connector 3. The disassembly screw rod 4, the connector 3, and the output shaft 2 of the speed reducer are coaxially arranged. A connecting member 9 is threadedly sleeved on the middle section of the disassembly screw rod 4. The periphery of the connecting member 9 is detachably connected to the inner wall of the wire rope drum 1 through three connecting rods 10 evenly distributed in the circumferential direction. Three reinforcing ribs 11 are evenly distributed in the circumferential direction on the inner wall of the wire rope drum 1. The three connecting rods 10 are respectively connected to the three reinforcing ribs 11 in a one-to-one correspondence. Both ends of the connecting rod 10 are detachably connected to the connecting member 9 and the reinforcing rib 11 of the wire rope drum 1 through a bolt and nut connection method.

[0019] When replacing the load platform speed reducer of the cigarette box high-rise warehouse stacker, it is necessary to disassemble the wire rope drum 1. During disassembly, first, thread the installation stud 5 at one end of the connector 3 into the threaded hole at the end of the output shaft 2 of the speed reducer. Screw the disassembly screw rod 4 into the central screw hole of the connecting member 9. One end of each of the three connecting rods 10 is connected to the connecting member 9 through a bolt and nut connection method. The other end of each of the three connecting rods 10 is connected to the three reinforcing ribs 11 on the inner wall of the wire rope drum 1 through a bolt and nut connection method, and make the positioning protrusion 7 of the disassembly screw rod 4 tightly press into the positioning hole 6 of the connector 3. Then, use a wrench to rotate the external hexagonal operation head 8 at the end of the disassembly screw rod 4 clockwise. Under the action of the threaded fit between the connecting member 9 and the disassembly screw rod 4, the connecting member 9 moves away from the output shaft 2 of the speed reducer, and drives the wire rope drum 1 to move together through the three connecting rods 10, gradually pulling the wire rope drum 1 away from the output shaft 2 of the speed reducer, and the disassembly operation of the wire rope drum 1 and the output shaft 2 of the speed reducer can be realized. The entire disassembly process is convenient, fast, time-saving and labor-saving, improves the operation efficiency, makes the replacement operation of the speed reducer more convenient, and reduces the operation difficulty and intensity of the maintenance personnel.
