[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 and Figure 2 An embodiment of this utility model provides an auxiliary tool for safety valve maintenance, including a support platform 1, a support plate 2 fixedly connected to the upper surface of the support platform 1, a first cylinder 3 fixedly connected inside the support plate 2, a slide plate 4 fixedly connected to the output end of the first cylinder 3, a limit plate 5 slidably connected inside the slide plate 4, the lower surface of the limit plate 5 fixedly connected to the upper surface of the support platform 1, a rack 6 fixedly connected to the upper surface of the slide plate 4, a gear 7 meshing with the tooth end of the rack 6, a support column 8 fixedly connected inside the gear 7, a fixing plate 9 rotatably connected to both ends of the support column 8, the lower surface of the fixing plate 9 fixedly connected to the upper surface of the support platform 1, and a rotating assembly provided on the outer wall of the support column 8.

[0024] Specifically, the support plate 2 is fixed to the upper surface of the support platform 1 to support and fix the first cylinder 3. By activating the first cylinder 3, the slide plate 4 can be pushed to slide. The limiting plate 5 is fixed to the upper surface of the support platform 1 to limit the sliding of the slide plate 4 and prevent the slide plate 4 from deviating during the sliding process. The slide plate 4 fixes the rack 6 and can drive the rack 6 to slide synchronously. The rack 6 and the gear 7 are always in a meshing state, which allows the gear 7 to rotate synchronously through the sliding of the rack 6. The gear 7 fixes the support column 8, thereby causing the support column 8 to rotate. The fixing plate 9 is fixed to the upper surface of the support platform 1 to provide stable support for the rotation of the support column 8, which allows the support column 8 to rotate stably.

[0025] Reference Figure 1 The rotating assembly includes a rotating block 10, the interior of which is fixedly connected to the outer wall of the support column 8, and a maintenance table 11 is fixedly connected to the upper surface of the rotating block 10.

[0026] Specifically, the support column 8 fixes the rotating block 10. When the support column 8 rotates, it will push the rotating block 10 to rotate synchronously. The maintenance platform 11 fixes the rotating block 10, thereby causing it to rotate and allowing the angle of the safety valve to be flexibly adjusted.

[0027] Reference Figure 1 , Figure 3 and Figure 4 The maintenance table 11 has a sliding groove 20 inside. A second cylinder 12 is fixedly connected inside the maintenance table 11, and a sliding seat 13 is fixedly connected to the output end of the second cylinder 12. A first rotating shaft 14 is rotatably connected inside the sliding seat 13, and one end of a rotating plate 15 is fixedly connected to the outer wall of the first rotating shaft 14. A second rotating shaft 16 is fixedly connected to the other end of the rotating plate 15, and a slider 17 is rotatably connected to the outer wall of the second rotating shaft 16. A limit strip 18 is slidably connected inside the slider 17, and the lower surface of the limit strip 18 is fixedly connected to the inside of the maintenance table 11. A connecting plate 19 is fixedly connected to the upper surface of the slider 17, and the outer wall of the connecting plate 19 is slidably connected to the inner wall of the sliding groove 20. A limit ring 21 is fixedly connected to the top of the connecting plate 19, and the limit rings 21 are symmetrically distributed on both sides of the maintenance table 11.

[0028] Specifically, the maintenance platform 11 serves to fix the second cylinder 12. Activating the second cylinder 12 causes it to push the sliding seat 13 to slide. The sliding seat 13 supports the first rotating shaft 14, and the rotating plate 15 also supports the first rotating shaft 14. When the first rotating shaft 14 slides, it pushes the rotating plate 15 to rotate. The rotating plate 15 supports the second rotating shaft 16, which connects the rotating plate 15 and the slider 17, allowing the slider 17 to slide synchronously via the rotation of the second rotating shaft 16. The limiting strip 18, fixed inside the maintenance platform 11, limits the slider 17, preventing it from shifting during sliding. The slider 17 is fixed to the connecting plate 19, which connects the slider 17 and the limiting ring 21, allowing the connecting plate 19 to slide against the inner wall of the slide groove 20, thus causing the limiting rings 21 on both sides to slide synchronously. The sliding of the limiting rings 21 on both sides limits and fixes the safety valve, ensuring its stability during maintenance.

[0029] Working principle: When this auxiliary tool is needed, place the safety valve to be repaired on the upper surface of the repair table 11, start the second cylinder 12 to push the sliding seat 13 to slide. When the sliding seat 13 slides, it will drive the first rotating shaft 14 inside to slide at the same time. During the sliding process, the first rotating shaft 14 will drive the rotating plate 15 and the second rotating shaft 16 to rotate. The rotation of the second rotating shaft 16 will pull the slider 17 to slide. During the sliding process, the slider 17 will drive the connecting plate 19 to slide against the inner wall of the slide groove 20. Thus, the sliding of the connecting plate 19 will drive the limit rings 21 on both sides to slide at the same time. This can limit and fix different safety valves, so as to maintain the stability of the safety valve during the repair process and avoid inaccurate operation or damage to parts due to the shaking or movement of the safety valve.

[0030] When the safety valve is fixed in position, it can be repaired. When repairs are needed at different positions of the safety valve, its angle can be adjusted. The first cylinder 3 is activated to push the slide plate 4 against the outer wall of the limit plate 5. As the slide plate 4 slides, it drives the rack 6 to slide synchronously. The rack 6 meshes with the gear 7. As the rack 6 slides, it drives the gear 7 to rotate. When the gear 7 rotates, it drives the internal support column 8 to rotate. During the rotation of the support column 8, it drives the repair platform 11 to rotate via the rotating block 10, thereby flexibly adjusting the angle of the safety valve. This allows for angle adjustment without moving the safety valve itself, meeting the repair needs of different positions and ensuring precise repairs. This tool not only achieves the effect of limiting and fixing different safety valves, maintaining the stability of the safety valve during repair, and avoiding inaccurate operation or damage to components due to valve shaking or movement, but also allows for angle adjustment without moving the safety valve itself, meeting the repair needs of different positions and ensuring precise repairs.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
