[0003] When using existing technology, the maintenance workbench may only be suitable for boilers of a specific size. For boilers that are larger or smaller, or boilers with damaged surfaces or irregular shapes, it may not be able to provide stable clamping and fixation when the user is performing maintenance. This may not only cause the boiler to shake or shift during operation, increasing the difficulty and risk of maintenance, but may also cause further damage to the boiler due to improper clamping. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the existing technology does not have a structure for clamping and fixing boilers of different specifications and with different damage conditions, which may cause the boiler to shake or shift during maintenance, increasing the difficulty and risk of maintenance. Therefore, we propose a boiler maintenance device for thermal power plants.

[0005] To achieve the above objectives, this application adopts the following technical solution: a boiler maintenance device for thermal power plants, comprising a workbench: a first lifting cylinder is installed at the bottom of the workbench, a support pad is installed at the telescopic end of the first lifting cylinder, a boiler body is placed on the top of the support pad, a first guide groove is provided at both ends of the top of the workbench, an extension block is slidably connected to the inner wall of the first guide groove, a first sliding groove is provided inside the extension block, a sliding buckle is slidably connected to the inner wall of the first sliding groove, a first servo motor is installed on one side of the top of the extension block, a support rod is installed at the output end of the first servo motor, a second servo motor is installed on one side of the top of the support rod, an elastic clamp is installed at the output end of the second servo motor, and several adjustment grooves are provided at both ends of the top of the workbench, with the two ends of the sliding buckle inserted into the inner wall of the adjustment groove.

[0015] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0016] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a boiler maintenance device for thermal power plants, including a workbench 1; a first lifting cylinder 2 is installed at the bottom of the workbench 1, a support pad 3 is installed at the telescopic end of the first lifting cylinder 2, and a boiler body 4 is placed on top of the support pad 3; a first guide groove 5 is opened at both ends of the top of the workbench 1, an extension block 6 is slidably connected to the inner wall of the first guide groove 5, a first sliding groove 7 is opened inside the extension block 6, and a sliding buckle 8 is slidably connected to the inner wall of the first sliding groove 7; a first servo motor 9 is installed on one side of the top of the extension block 6, a support rod 10 is installed at the output end of the first servo motor 9, a second servo motor 11 is installed on one side of the top of the support rod 10, and an elastic clamp 12 is installed at the output end of the second servo motor 11; several adjustment grooves 13 are opened at both ends of the top of the workbench 1. Both ends of buckle 8 are inserted into the inner wall of adjustment groove 13. The inner wall of the first sliding groove 7 is provided with a second sliding groove 14 on both sides. The inner wall of the second sliding groove 14 is slidably connected with a slider 15. One side of the slider 15 is fixedly connected to both sides of the bottom of the buckle 8. The inner side of the buckle 8 is fixedly connected with a spring 16. The other end of the spring 16 is fixedly connected to one side of the inner wall of the first sliding groove 7. An anti-slip pad 17 is installed on one side of the elastic clamp 12. The first guide groove 5 is provided with a second guide groove 18 on both sides. The extension block 6 is fixedly connected with a shaft 19 on both sides. An auxiliary wheel 20 is installed on the surface of the shaft 19. The top of the support pad 3 is provided with anti-slip texture 21. Universal wheels 22 are installed around the bottom of the workbench 1. Two second lifting cylinders 23 are installed on both sides of the workbench 1. Support feet 24 are installed on the telescopic ends of the second lifting cylinders 23. Specifically: When the user prepares to inspect the boiler body 4, the second lifting cylinder 23 is driven via the control panel on one side of the workbench 1. This retracts the support legs 24 upwards, allowing the casters 22 mounted on the bottom of the workbench 1 to contact the ground. The user can then use the casters 22 to move the equipment closer to the boiler body 4. The user then places the boiler body 4 on top of the support pad 3. The anti-slip texture 21 on the top of the support pad 3 increases the friction between the boiler body 4 and the support pad 3, effectively preventing the boiler body 4 from sliding or shifting during inspection. The user can activate the first lifting cylinder 2 via the controller. The telescopic movement of cylinder 2 drives the support pad 3 and the boiler body 4 placed on it to adjust their height, so that the boiler body 4 can be adjusted to a position convenient for the user's operation according to the user's maintenance needs. When the height of the support pad 3 is adjusted, the user moves the sliding buckle 8 upward along the inner wall of the first sliding groove 7. The sliders 15 on both sides of the bottom of the sliding buckle 8 move through the inner wall of the second sliding groove 14 opened on both sides of the inner wall of the first sliding groove 7, so that the sliding buckle 8 will not disengage from the inner wall of the first sliding groove 7 when it moves upward. When the sliding buckle 8 moves upward, the pins at both ends of the sliding buckle 8 disengage from the inner wall of the adjusting groove 13. At the same time, the sliding buckle 8 pulls the spring 16, which stores and stretches its force. At this time, the user moves the extension block 6 through the two side shafts 1. The auxiliary wheel 20 mounted on the surface of the boiler body 4 moves along the inner wall of the second guide groove 18, making the extension block 6 more stable when moving along the inner wall of the first guide groove 5, and making it easier and less strenuous for the user to adjust the position of the extension block 6. After the user moves the extension block 6 to the appropriate position on the inner wall of the first guide groove 5 according to the specifications of the boiler body 4, the user releases the sliding buckle 8, causing the spring 16 to release and retract, pulling the sliding buckle 8 so that the pins at both ends of the sliding buckle 8 insert into the inner wall of the adjusting groove 13 to fix the position of the extension block 6. At this time, the user will drive the first servo motor 9 and the second servo motor 11 at the top of the extension block 6 through the controller, and adjust the support rod 10 and the elastic clamp 1 according to the surface and shape of the boiler body 4. 2. Adjustments are made to clamp the boiler body 4 with the elastic clamps 12 on both sides, fixing the position of the boiler body 4. The elasticity of one end of the elastic clamp 12 allows its surface to fit tightly against the surface of the boiler body 4. The protective anti-slip pad 17 on one side of the elastic clamp 12 prevents wear caused by unevenness or wear protrusions on the surface of the boiler body 4 during clamping. This further improves the stability of clamping the boiler body 4, ensuring that the boiler body 4 will not shake or shift during maintenance, guaranteeing the accuracy of maintenance operations, and providing good protection for the components being maintained, thus extending the service life of the equipment.

[0017] Working Principle: When the user prepares to overhaul the boiler body 4, firstly, the second lifting cylinder 23 is activated via the control panel on one side of the workbench 1, causing the support legs 24 to retract upwards, thus bringing the casters 22 at the bottom of the workbench 1 into contact with the ground. At this time, the user can easily move the equipment near the boiler body 4 using the casters 22. Next, the boiler body 4 is placed on top of the support pad 3, using the anti-slip texture 21 on the surface of the support pad 3 to increase friction and prevent the boiler body 4 from sliding or shifting during the overhaul. The first lifting cylinder 2 is activated via the controller to adjust the height of the support pad 3 and the boiler body 4. Once the height of the support pad 3 is adjusted to the correct position, the user moves the sliding buckle 8 upwards along the first slide groove 7, using the sliders 15 on both sides of the bottom of the sliding buckle 8 to move within the second slide groove 14, ensuring the sliding buckle 8 rises stably. The pins at both ends of the sliding buckle 8 move out of the adjustment groove 1. The extension block 6 is disengaged from the boiler body 4 by pulling the spring 16 to stretch and store force. The user moves the extension block 6 in the second guide groove 18 using the auxiliary wheels 20 on the two shafts 19 on both sides of the extension block 6. The position of the extension block 6 in the first guide groove 5 is adjusted to fit the specifications of the boiler body 4. The sliding buckle 8 is released, the spring 16 retracts, and the pins at both ends of the sliding buckle 8 are re-inserted into the adjustment groove 13 to fix the position of the extension block 6. The controller drives the first servo motor 9 and the second servo motor 11 at the top of the extension block 6 to adjust the position of the support rod 10 and the elastic clamp 12 so that the elastic clamp 12 on both sides clamps the boiler body 4. The elastic design of the elastic clamp 12 allows its surface to fit tightly against the boiler body 4, and the anti-slip pad 17 protects the surface of the boiler body 4 to avoid wear. This ensures that the boiler body 4 remains stable during maintenance, ensuring the accuracy of maintenance operations and the service life of the equipment.

[0018] 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.
