The working principle of the utility model is as follows:

when the high-lift water pump is assembled, a plurality of guide shells 29 are required to be assembled in sequence, and an independent impeller 30 is arranged in each guide shell 29, so that the guide shells 29, the impellers 30, the guide shells 29 and the impellers 30 and … … are required to be assembled in sequence.

During assembly, the corner lifting cylinders 19 and the center lifting cylinders 21 in each lifting support mechanism 8 extend out, so that the end parts of piston rods of the center lifting cylinders 21 are in contact with the plugging rods 7, and the plugging rods 7 are supported through the center lifting cylinders 21 in each lifting support mechanism 8, so that the plugging rods 7 are prevented from sagging at a certain position. At the same time, the supporting plate 18 inside each lifting supporting mechanism 8 is at the highest position and keeps a certain distance with the plugging rod 7.

Then, the first guide shell 29 and the impeller 30 are sleeved on the plugging rod 7 from the free end of the plugging rod 7, then the second chain transmission mechanism in the second moving mechanism starts to operate, the second moving frame 12 is driven to move towards one end of the supporting frame 6, after the second moving frame 12 reaches the position of the plugging rod 7, the guide shell 29 and the impeller 30 are pushed to move towards one end of the supporting frame 6, when the guide shell 29 and the impeller 30 pass through the first lifting supporting mechanism 8 on the right side, the controller controls the corner lifting oil cylinders 19 and the center lifting oil cylinders 21 in the first lifting supporting mechanism 8 on the right side to retract, and thus the piston rod and the supporting plate 18 descend and can not block the passage of the guide shell 29 and the impeller 30. After the guide shell 29 and the impeller 30 pass through the first lifting support mechanism 8 on the right side, the controller controls the first lifting support mechanism 8 on the right side to ascend again to support the inserting rod 7 again, and simultaneously controls the next lifting support mechanism 8 to descend, so that the guide shell 29 and the impeller 30 can continuously advance, and the process is repeated until the guide shell 29 is contacted with the support frame 6 on the left side. By regularly descending and ascending the lifting support mechanism 8, the diversion shell 29 can be continuously advanced under the premise of ensuring the supportability of the inserting and connecting rod 7. When the guide shell 29 contacts with the supporting frame 6, the second movable seat returns to the right under the action of the second chain transmission mechanism, and finally returns to the initial position again.

When the first diversion shell 29 contacts with the supporting frame 6, the first chain transmission mechanism starts to operate, the first movable frame 9 is driven to move towards one side of the supporting frame 6, and when the first movable frame 9 moves in place, the first chain transmission mechanism stops operating. Next, the two second clamping rods 27 approach each other under the left and right of the two second clamping cylinders 28, so that the semicircular grooves on the two second clamping rods 27 form a complete circular arc groove, and the two first clamping rods 25 maintain the maximum angle at this time. Then the movable oil cylinder 10 is controlled to extend, the movable plate 14, the first clamping mechanism 16 and the second clamping mechanism 17 are driven by the movable oil cylinder 10 to synchronously move to one side of the supporting frame 6, the circular arc grooves on the two second clamping rods 27 act on the guide shell 29 after passing through the impellers 30, and the guide shell 29 is tightly attached to the supporting frame 6 through the extending of the movable oil cylinder 10. Then the movable oil cylinder 10 is retracted, the two second clamping rods 27 are opened, the two first clamping rods 25 are tightened, and the movable oil cylinder 10 is extended again, so that the circular arc grooves on the two first clamping rods 25 act on the impeller 30, and the impeller 30 is tightly attached to the guide shell 29. This completes the installation of a shell 29 and impeller 30, and the first displacement mechanism does not resume its initial position, continues to remain in a position close to the support frame 6, but withdraws the displacement cylinder 10.

Then, the free end of the connecting rod 7 is sleeved with a guide shell 29 and an impeller 30 again, and the above process is repeated, so that the next guide shell 29 and the impeller 30 are arranged at the rear sides of the previous guide shell 29 and the impeller 30, and the contact tightness between each guide shell 29 and the impeller 30 is ensured through the first clamping mechanism 16, the second clamping mechanism 17 and the mobile oil cylinder 10. When the guide shells 29 move on the plugging rods 7, the guide shells 29 can be manually rotated to ensure that the bolt holes on each guide shell 29 are correspondingly arranged after the guide shells 29 are installed.
