[0032] Example 3

[0033] See also Figure 1-4 A bidirectional threaded rod 16 is rotatably connected to one side of the connecting block 11, and the bidirectional threaded rod 16 is threadedly connected to the fixed block 13. A turntable 19 is fixedly connected to one end of the bidirectional threaded rod 16.

The disassembly or installation of the support block 12 can be quickly completed by rotating the bidirectional threaded rod 16, which is convenient for the staff to replace the damaged support block 12.

[0034] Working principle: First, when the platform is used for maintenance, the cart 1 is moved to the maintenance site, and then the brakes of the wheels at the bottom of the cart 1 are activated to preliminarily fix the cart 1, and then the locking cylinder 6 is activated. The locking cylinder 6 drives the push plate 7 to move, and the movement of the push plate 7 drives the sliding rod 8 to move. The movement of the sliding rod 8 drives the sliding frame 9 to move, and the movement of the sliding frame 9 drives the lifting rod 10 to move horizontally. Since the lifting rod 10 is rotatably connected to one end of the connecting rod 15, and the other end of the connecting rod 15 is rotatably connected to the outer side of the cart 1, and the lifting rod 10 is slidably connected to the sliding frame 9, the lifting rod 10 moves horizontally and vertically at the same time, and the vertical movement of the lifting rod 10 drives the connecting block 11 to move, and the movement of the connecting block 11 drives the support block 12 to move, and the support block 12 moves in contact with the ground. The side of the cart 1 is fixed and supported by four groups of support blocks 12, thereby reducing the possibility of the cart 1 tipping over and ensuring the maintenance efficiency of the sewage pumping station;

[0035] Secondly, when the damaged support block 12 needs to be replaced, the two-way threaded rod 16 is rotated. Since the two-way threaded rod 16 is threadedly connected to the fixing block 13, and the fixing block 13 is slidably connected to the connecting block 11, the rotation of the two-way threaded rod 16 drives the fixing block 13 to move under the influence of the thread, and the fixing block 13 moves and separates from the groove on the inner side of the support block 12, thereby releasing the fixation of the support block 12. The disassembly can be completed by manually pulling the support block 12, and then the groove of the new support block 12 is aligned with the position of the fixing block 13, and the new support block 12 is pushed upward, and the two-way threaded rod 16 is rotated in the opposite direction. The two-way threaded rod 16 rotates in the opposite direction to drive the fixing block 13 to move and insert into the groove on the inner side of the support block 12 to complete the fixation. The operation is simple and convenient for the staff to replace the damaged support block 12.
