DETAILED DESCRIPTION

[0020] It is easy to understand that according to the technical scheme of the present application, a person skilled in the art can propose a plurality of structure modes and implementation modes which can be replaced with each other without changing the essential spirit of the present application. Therefore, the following specific embodiments and drawings are only exemplary description of the technical scheme of the present application, and should not be regarded as the whole or regarded as the limitation or restriction of the technical scheme of the present application.

[0021] According to one embodiment of the present application combined with Figures 1-4 is shown.

[0022] As Figure 1As shown, for the overall structure, a maintenance platform for controlling a transformer includes: a frame 1, a drive unit 2 fixed to the bottom of the frame 1, and vertical guide rails 3 symmetrically arranged on both sides of the inner wall of the frame 1. A slide plate 4 is slidably connected to each of the vertical guide rails 3. The drive unit 2 is used to drive the slide plate 4 to slide linearly on the vertical guide rail 3. A locking cylinder 5 is fixedly connected to each of the vertical guide rails 3 and the two locking cylinders 5 are symmetrical about the center of the frame 1 and their output ends are arranged opposite each other. A clamping block 6 is fixed to the output end of each locking cylinder 5. The opposite side of the two clamping blocks 6 is a smooth plane to press against the metal shell of the external control transformer.

[0023] As can be seen, in this implementation, the locking blocks are driven by two oppositely arranged locking cylinders 5 to press and fix the external control transformer, which then facilitates various tests by maintenance personnel. The locking blocks only contact the metal shell of the transformer during the pressing process and do not involve the terminal block, making it stable and reliable. At the same time, the equipment can raise and lower the transformer to a fixed position through the bottom-mounted drive component 2, further facilitating different height requirements during the maintenance process.

[0024] like Figure 2 and Figure 3 As shown, regarding the selection of the driving component 2, in this embodiment, the driving component 2 includes a servo motor 7, a transmission chain 8, a sprocket 9, a central shaft 10, and a reversing assembly 11. The servo motor 7 is fixed to the inner bottom of the platform 1 by a motor mounting base. Rotating platforms 12 corresponding to the ends of the central shaft 10 are fixed on both sides of the inner wall of the platform 1. The central shaft 10 is rotatably connected to the rotating platform 12. The sprocket 9 is coaxially fixed to the output ends of the central shaft 10 and is driven by the transmission chain 8. The reversing assembly 11 includes two sets, which are respectively arranged at the ends of the central shaft 10. It is used to convert the rotational force of the central shaft 10 into the driving force for the slide plate 4 to slide on the vertical guide rail 3.

[0025] Furthermore, each of the reversing components 11 includes a gear 13, a rack 14, a connecting column 15, and a guide rod 16. The gear 13 is coaxially fixed to the end of the central shaft 10 and meshes with the rack 14. The back of the rack 14 is attached and fixed to the connecting column 15. The connecting column 15 is parallel to the vertical guide rail 3, and its two ends are fixed to the ends of the guide rod 16 through fixed extension plates 17. The inner wall of the frame 1 is also fixed with a bearing seat 18 at the corresponding guide rod 16, and the guide rod 16 is slidably connected in the bearing seat 18.

[0026] Furthermore, the length of the guide rod 16 is set to be greater than the length of the rack 14.

[0027] As described above, after the servo motor 7 outputs rotation, it can drive the central shaft 10 inside the rotating table 12 to rotate through the sprocket 9 and the transmission chain 8. The central shaft 10 synchronously drives the gears 13 at both ends to rotate. Due to the meshing action of the gears 13 and the rack 14, the rack 14 can move up and down linearly according to the different directions of the gears 13. The connecting column 15 on the back of the rack 14 can synchronously drive the back plate to move up and down. The lifting process is limited by the slide rail on the back of the slide plate 4 and the guide rod 16 within the bearing seat 18 to ensure that the direction remains unchanged and that it is stable and reliable.

[0028] like Figure 4 As shown, the vertical guide rails 3 include four rails, which are symmetrically fixed in pairs on both sides of the inner wall of the frame 1. The back of the slide plate 4 is slidably mounted on the two vertical guide rails 3 on one side of the inner wall of the frame 1. The front of the slide plate 4 is fixed with a support frame 19 in a triangular manner by a connecting rod. The locking cylinder 5 is fixedly connected to the support frame 19. The clamping block 6 is exposed outside the support frame 19.

[0029] Similarly, in this embodiment, the stand 1 is a box structure formed by bending sheet metal into one piece, with an opening on the front corresponding to the external control transformer for operator inspection. During the inspection process, the operator can operate each inspection instrument face-to-face, without having to operate it by hand like in the past.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
