Its structure and principle can be known to those skilled in the art through technical manuals or 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. The first motor 2 drives the threaded screw 3 to rotate, and 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, it can ensure that the threaded sleeve 31 can 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. The staff can rotate the first moving rod 11 in the circumferential direction of the lower circular mounting ring 7 and the upper circular mounting ring 8, that is, the first moving rod 11 can be moved with the assistance of the third sliding component, thereby adjusting the position of the arc plate 27 and allowing 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. When the connecting rod 18 moves, it can drive the movable rod 14 to move. 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. 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, limiting the impeller groove 30 to ensure that the impeller groove 30 will not move during disassembly.
[0056] The vertical centrifugal pump auxiliary disassembly platform 1 of the embodiment of the present invention, the staff starts the jack 6, the jack 6 can jack up the vertical centrifugal pump, so it is convenient to disassemble the vertical centrifugal pump, when the centrifugal pump body 5 casing is disassembled, by starting the first motor 2, the first motor 2 drives the threaded screw 3 to rotate, the first threaded screw 3 can drive the threaded sleeve 31 to move, and 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, the staff can rotate the first moving rod 11 in the circumferential direction of the lower circular mounting ring 7 and the upper circular mounting ring 8, that is, the first moving rod 11 can slide in the third direction. The second movable rod 15 can be moved with the assistance of the first sliding component, thereby adjusting the position of the arc plate 27 and allowing the second movable rod 15 to move so that the second movable rod 15 can be aligned with the impeller groove 30 in the impeller 28. 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 drive the movable component to move. The movable component moves in conjunction with the first sliding component, thereby pushing the second movable rod 15 to move. 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, limiting the impeller groove 30 and ensuring that the impeller groove 30 will not move during disassembly, thereby improving the convenience and safety of the centrifugal pump when it needs maintenance. This avoids the situation where the centrifugal pump is often disassembled using an electric hoist or a hand hoist, and the seal between the pump casing and the pump seat is damaged during disassembly and installation because the hoist and other lifting tools cannot control the force. At the same time, it avoids the need to use tools to lock the impeller of the centrifugal pump due to its own rotation when disassembling it. 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.
