[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0025] Example 1, referring to Figs. 1-4 This is the first embodiment of the present invention. This embodiment provides an adjustable mechanism that allows workers to move and inspect the stator and rotor while standing or sitting, thereby improving maintenance efficiency.

[0026] Specifically, the mechanism includes: a sliding component 1, which includes a sliding tray 11 and a first slide rail 12 disposed on the sliding tray 11; The flipping component 2 includes a flipping tray 21 and a second slide rail 22 disposed on the flipping tray 21.

[0027] Furthermore, the first slide rail 12 is located inside the second slide rail 22, and the first slide rail 12 is slidably connected to the second slide rail 22.

[0028] Furthermore, there are two sets of the first slide rail 12 and the second slide rail 22, and the two sets of the first slide rail 12 are symmetrically arranged on both sides of the sliding tray 11, and the two sets of the second slide rail 22 are also symmetrically arranged on both sides of the flip tray 21.

[0029] Furthermore, the sliding assembly 1 also includes a support frame 13 fixedly disposed at the bottom of the sliding tray 11, and a handle 14 fixedly disposed on one side of the sliding tray 11.

[0030] Furthermore, the flipping assembly 2 also includes a support wheel 23 fixedly disposed at the bottom of the second slide rail 22, and a hinge seat 24 fixedly connected to one side of the second slide rail 22.

[0031] Furthermore, each set of second slide rails 22 is equipped with a set of support wheels 23 and a set of hinge seats 24.

[0032] It should be noted that when workers stand on the tilting tray 21 or the sliding tray 11 to inspect the stator and rotor, the function of the support wheel 23 is to provide support for the tilting tray 21 and the sliding tray 11, so that the workers have a stable working platform.

[0033] In use, first pull the handle 14 away from the tilting tray 21 to disengage the sliding tray 11 from the second slide rail 22 via the first slide rail 12. Adjust the distance between the sliding tray 11 and the tilting tray 21 according to the position of the magnetic yoke bolts on the stator and rotor, thereby improving the maintenance efficiency of the staff.

[0034] In summary, this utility model, through the design of the sliding component and the flipping component, realizes the relative sliding and position adjustment between the sliding tray and the flipping tray. Workers can flexibly adjust the distance between the sliding tray and the flipping tray according to the position of the magnetic yoke bolts on the stator and rotor, thereby quickly locating the part that needs to be inspected and greatly improving the maintenance efficiency.

[0035] Example 2, refer to Figs. 1-4 This is the second embodiment of the present invention. Unlike the first embodiment, this embodiment also provides a pallet truck for overhauling the stator and rotor of a water turbine generator. This truck can eliminate the risk of bumps and falls when workers are overhauling the stator and rotor, thus improving safety performance.

[0036] Specifically, it includes: guide assembly 3, and electric mobile vehicle 4 disposed on one side of guide assembly 3.

[0037] Furthermore, the guide assembly 3 includes a mounting plate 31, two sets of mounting shafts 32 symmetrically arranged on the mounting plate 31, and a magnetic wheel 33 rotatably connected to one end of the mounting shaft 32; Each set of mounting shafts 32 is equipped with a set of magnetic wheels 33.

[0038] It should also be noted that the magnetic wheel 33 serves two purposes: firstly, the magnetic wheel 33 contacts the edges of the stator and rotor, and the magnetic attraction between the two sets enables the device to maintain stability during movement; secondly, it effectively prevents the electric vehicle 4 from colliding with the edges of the stator and rotor during operation, thereby improving the service life of the electric vehicle 4 and enhancing its safety performance.

[0039] Furthermore, the end of the hinge seat 24 away from the second slide rail 22 is fixedly connected to the side wall of the electric mobile vehicle 4.

[0040] Furthermore, the electric vehicle 4 has a drive mechanism 41 at its bottom, and a control handle 42 is connected to the drive mechanism 41.

[0041] In use, the drive mechanism 41 is first activated via the control handle 42, which moves the electric trolley 4. Workers stand or sit on the sliding tray 11 to perform 360° inspection of the stator and rotor. The relative distance between the sliding tray 11 and the tilting tray 21 is then adjusted to inspect the magnetic yoke bolts at different positions on the stator and rotor. After inspecting the stator and rotor, the first slide rail 12 on the sliding tray 11 is retracted into the second slide rail 22. At this point, the sliding tray 11 and the tilting tray 21 overlap. The tilting tray 21 is then rotated onto the electric trolley 4 via the hinge seat 24, thus achieving storage of both the sliding tray 11 and the tilting tray 21 and improving the convenience of the device.

[0042] In summary, the magnetic wheel of this invention can contact the edges of the stator and rotor and be attracted by magnetic force, effectively preventing the electric mobile vehicle from colliding with the edges of the stator and rotor during movement, eliminating the risk of workers falling, and significantly improving the safety of maintenance work; the sliding tray can be retracted into the second slide rail through the first slide rail, and the flipped tray can also be rotated onto the electric mobile vehicle through the hinge seat to realize the storage of the tray and improve the convenience of the equipment.

[0043] The rest of the structure is the same as in the above embodiments.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
