[0052] It should be noted that the present invention is a vertical centrifugal pump auxiliary disassembly platform, and each component is a universal standard component or a component known to technical personnel in this field. Its structure and principle can be known to technical personnel through technical manuals or through conventional experimental methods.

[0053] Working principle: First, the vertical centrifugal pump is placed on the disassembly platform 1. At this time, the staff starts the jack 6, which can lift the vertical centrifugal pump, so it is convenient to disassemble the vertical centrifugal pump. When the shell of the centrifugal pump body 5 is disassembled, the first motor 2 is started, and the first motor 2 drives the threaded screw 3 to rotate. The first threaded screw 3 can drive the threaded sleeve 31 to move. Because the two threaded sleeves 31 are respectively fixedly connected to the lower circular mounting ring 7 and the upper circular mounting ring 8, the threaded sleeve 31 can be guaranteed to move.

[0054] When the threaded sleeve 31 moves, it can respectively drive the lower circular mounting ring 7 and the upper circular mounting ring 8 to move, until the lower circular mounting ring 7 and the upper circular mounting ring 8 move to the impeller 28 provided in the centrifugal pump body 5. At this time, the staff can rotate according to the first moving rod 11, and the first moving rod 11 can move with the assistance of the third sliding component, so as to adjust the position of the arc plate 27, and also allow the second moving rod 15 to move, so that the second moving rod 15 can be aligned with the impeller groove 30 in the impeller 28;

[0055] When the alignment is completed, by starting the electric push rod 23, the electric push rod 23 can push the connecting rod 18 to move, and when the connecting rod 18 moves, it can drive the movable rod 14 to move, and when the movable rod 14 moves, it can drive the first ball 13 to move in the arc groove 12, thereby pushing the second movable rod 15 to move, and when the second movable rod 15 moves, it can move horizontally with the assistance of the second sliding component, so that the second movable rod 15 can be inserted into the impeller groove 30, and the impeller groove 30 is limited to ensure that the impeller groove 30 will not move during disassembly.

[0056] The auxiliary disassembly platform 1 of the vertical centrifugal pump of the embodiment of the present invention is started by a worker, and the jack 6 can lift up the vertical centrifugal pump, so that it is convenient to disassemble the vertical centrifugal pump. When the outer shell of the centrifugal pump body 5 is disassembled, the first motor 2 is started, and the first motor 2 drives the threaded screw 3 to rotate. The first threaded screw 3 can drive the threaded sleeve 31 to move. When the threaded sleeve 31 moves, it can respectively drive the lower circular mounting ring 7 and the upper circular mounting ring 8 to move, until the lower circular mounting ring 7 and the upper circular mounting ring 8 move to the impeller 28 set in the centrifugal pump body 5. At this time, the worker can rotate according to the first moving rod 11, and the first moving rod 11 can be assisted by the third sliding component. The second moving rod 15 can be moved to adjust the position of the arc plate 27, and the second moving rod 15 can be moved to align the second moving rod 15 with the impeller 28 groove in the impeller 28. When the alignment is completed, the electric push rod 23 is started, and the electric push rod 23 can push the connecting rod 18 to move and drive the movable part to move. The movable part moves in cooperation with the first sliding part, so it can push the second moving rod 15 to move. When the second moving rod 15 moves, it can move horizontally with the assistance of the second sliding part. Therefore, the second moving rod 15 can be inserted into the impeller 28 groove to limit the impeller 28 groove, ensuring that the impeller 28 groove will not move during disassembly, thereby improving the convenience and safety of the centrifugal pump to be repaired. It avoids the centrifugal pump often uses electric hoists or hand hoists for disassembly. Because the hoist and other lifting tools cannot control the force, the seal between the pump casing and the pump seat may be damaged during disassembly and installation. At the same time, in order to avoid the need to use tools to lock the impeller of the centrifugal pump due to its own rotation during disassembly, conventional tools are inconvenient to use, resulting in damage to the impeller due to improper operation, the auxiliary disassembly platform 1 of the embodiment of the present application can improve the convenience and efficiency of the disassembly operation.
