[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 5 This utility model provides a technical solution: a support device, comprising: a support frame 1; a bidirectional lead screw 2 rotatably disposed inside the support frame 1, with movable sliders 3 symmetrically mounted on the outer side of the bidirectional lead screw 2, the movable sliders 3 being slidably connected to the support frame 1; a support box 4 bolted to the top of the movable sliders 3, the support box 4 being slidably connected to the support frame 1; a movable support plate 29 slidably disposed inside the support box 4, with a support frame 6 bolted to the top of the movable support plate 29; a protective support 10 bolted to the inside of the support frame 6; and an outer fixed frame. 5 is fixed to the outside of the support box 4, and the outer fixed frame 5 is slidably connected to the support frame 1; the inner sliding block 26 is symmetrically slidably disposed inside the outer fixed frame 5, and the inner side of the inner sliding block 26 is fixedly connected to the limiting block 27, which is slidably connected to the outer fixed frame 5 and the support box 4. The bottom of the limiting block 27 is provided with an inclined surface 28; the side slots 23 are symmetrically and equidistantly disposed on the outside of the movable support plate 29, and the side slots 23 cooperate with the limiting blocks 27; the adjustment part is disposed on one side of the outer fixed frame 5 and is connected to the inner sliding block 26.

[0028] It should be noted that in this embodiment, by rotating the limiting nut 25 upward and pressing the external threaded rod 24 downward, the external threaded rod 24 drives the inner sliding plate 18 to move downward. The inner sliding plate 18 drives the adjusting groove 19 to move downward. The inner sliding plate 18 pushes against the side fixing rod 20 through the adjusting groove 19. The side fixing rod 20 drives the limiting slider 16, the inner sliding block 26, and the limiting block 27 to move. The limiting slider 16 slides on the outside of the second limiting slider 17. The inner sliding block 26 drives the limiting block 27 to move away from the limit between it and the side groove 23. Thus, the height position of the moving support plate 29 can be adjusted downward. When the inner sliding plate 18 is pressed downward, it will press the spring 22. When the pressure on the external threaded rod 24 is released, the spring 22 will... 2 will reset and drive the inner sliding plate 18, adjusting groove 19 and side fixing rod 20 to reset. The limiting block 27 on one side of the inner sliding block 26 limits the side groove 23 at the new height position, restricting the downward movement of the moving support plate 29. When it is necessary to adjust the height of the moving support plate 29 and the support frame 6 upward, the support frame 6 and the moving support plate 29 are directly lifted upward. The side grooves 23 on both sides of the moving support plate 29 will push the inclined surface 28 at the bottom of the limiting block 27. The side grooves 23 push the limiting block 27, the inner sliding block 26 and the side fixing rod 20 to move through the inclined surface 28. The side fixing rod 20 drives the inner sliding plate 18 to slide in the first side fixing box 14 through the adjusting groove 19. The inner sliding plate 18... When spring 22 is pressed and limit block 27 reaches the side slot 23 position, spring 22 will reset and drive inner sliding plate 18, adjusting groove 19, side fixing rod 20, inner sliding block 26 and limit block 27 to reset, limiting the downward movement of moving support plate 29 and side slot 23. Then, limit nut 25 is installed on the outer thread of external thread pressure rod 24, with the bottom of limit nut 25 abutting against the first side fixing box 14, limiting the movement of external thread pressure rod 24 and inner sliding plate 18. This allows for the adjustment and fixing of the height of moving support plate 29 and support frame 6. The device is centrally controlled by an external controller, and the output of servo motor 13 drives bidirectional screw 2 to rotate. Rod 2 drives the symmetrically moving slider 3 on the outside to move. The moving slider 3 drives the support box 4, the outer fixed frame 5, the moving support plate 29 and the support frame 6 to adjust their positions. The distance between the two support frames 6 and the protective support 10 is adjusted to accommodate water pump rotors of different lengths. The water pump rotor that needs to be inspected and maintained is placed on the protective support 10. Both the protective support 10 and the auxiliary clamp 9 are equipped with protective pads to protect the support points of the water pump rotor and prevent damage to the water pump rotor. The output end of the cylinder 7 drives the adjusting support plate 8 and the auxiliary clamp 9 to move downward. The auxiliary clamp 9 and the protective support 10 cooperate to restrict the support position of the water pump rotor and prevent the water pump rotor from falling off the protective support 10.

[0029] In one embodiment, such as Figures 1 to 5 As shown, the adjustment unit includes a first side fixing box 14. The first side fixing box 14 is fixedly connected to one side of the outer fixing frame 5. An inner sliding plate 18 is slidably arranged inside the first side fixing box 14.

One end of the side fixing rod 20 is fixedly connected to the inner sliding block 26. The side fixing rod 20 is slidably connected to the first side fixing box 14 and to the outer fixing frame 5.

[0030] It should be noted that, in this embodiment, when the inner sliding plate 18 moves, it drives the side fixing rod 20 to move through the symmetrically opened adjustment groove 19 inside. When the side fixing rod 20 moves, it drives the inner sliding block 26 and the limiting block 27 to move, which facilitates the disassembly of the limiting block 27 and the side groove 23.

[0031] In one embodiment, such as Figures 1 to 5 As shown, an external threaded pressure rod 24 is fixedly connected to the top of the inner sliding plate 18. The top of the first side fixed box 14 is provided with a movable through hole that mates with the external threaded pressure rod 24. A limit nut 25 is installed on the outer thread of the external threaded pressure rod 24. A third limit slide rod 21 is symmetrically slidably arranged inside the inner sliding plate 18. The third limit slide rod 21 is fixedly connected to the first side fixed box 14. Multiple springs 22 are equidistantly installed inside the first side fixed box 14. The top of the springs 22 is connected to the inner sliding plate 18.

[0032] It should be noted that in this embodiment, the inner sliding plate 18 is pressed by the external threaded pressure rod 24, the side fixing rod 20 is moved by the adjustment groove 19 opened inside the inner sliding plate 18, and the pressing position of the inner sliding plate 18 is reset by the spring 22.

A second limit slider 17 is symmetrically slidably arranged inside the limit slider 16 and is fixedly connected to the second side fixing box 15.

[0034] It should be noted that, in this embodiment, when the side fixing rod 20 moves, it causes the limiting slider 16 to slide within the second side fixing box 15. The limiting slider 16 slides to the outside of the second limiting slider 17, thereby improving the adjustment stability of the limiting slider 16 and the side fixing rod 20.

[0035] In one embodiment, such as Figures 1 to 5As shown, a cylinder 7 is bolted to the top of the support frame 6, and an adjusting support plate 8 is provided at the output end of the cylinder 7. The adjusting support plate 8 is slidably connected to the support frame 6. An auxiliary clamp 9 is bolted to the bottom of the adjusting support plate 8, and a limit rod 11 is symmetrically fixed to the top of the adjusting support plate 8. The limit rod 11 is slidably connected to the support frame 6.

[0036] It should be noted that in this embodiment, the output end of the cylinder 7 drives the adjusting support plate 8 and the auxiliary clamp 9 to move downward. The auxiliary clamp 9 and the protective support 10 cooperate to limit the support position of the water pump rotor, so as to prevent it from falling off the protective support 10.

[0037] In one embodiment, such as Figures 1 to 5 As shown, a first limit slide rod 12 is symmetrically slidably arranged inside the movable slider 3. The first limit slide rod 12 is fixedly connected to the support frame 1. A servo motor 13 is installed on one side of the support frame 1 by bolts. The output end of the servo motor 13 is fixedly connected to the bidirectional lead screw 2.

[0038] It should be noted that in this embodiment, the output end of the servo motor 13 drives the bidirectional lead screw 2 to rotate, and the bidirectional lead screw 2 drives the outer symmetrical movable slider 3 to slide within the support frame 1. The movable slider 3 slides to a limit outside the first limit slider 12, which restricts the overall movement position of the movable slider 3, the support box 4, and the movable support plate 29, thereby improving stability.
