[0002] In the daily operation of thermal power plants, steam turbine maintenance is a key link in ensuring the stable operation of power generation equipment. During maintenance work, a mobile platform is needed. The steam turbine maintenance mobile platform is a special equipment platform used for the maintenance and overhaul of large power generation equipment such as thermal power plants and nuclear power plants. The main function of this platform is to provide maintenance personnel with a stable working platform. The mobile platform can move freely between different maintenance points of large equipment such as steam turbines and generators, allowing maintenance personnel to reach different work areas more conveniently. It can also store maintenance accessories, thereby improving maintenance efficiency and ensuring work safety.

[0003] Traditional steam turbine maintenance platforms are mostly fixed-height metal structures, typically welded from steel beams and plates, with wheels installed on the bottom for mobility. For storing accessories, simple tool boxes or shelves are usually used to place various tools and accessories.

[0004] However, due to the fixed height of traditional steam turbine maintenance platforms, when the maintenance work involves components at different heights of the steam turbine, personnel are required to constantly climb to high places to repair components at different heights. This not only increases the maintenance preparation time, but also frequently climbs up and down, which reduces the maintenance efficiency and increases the safety risks of maintenance personnel during the climbing process. Therefore, a mobile steam turbine maintenance platform with a spare parts storage mechanism for thermal power plants is proposed to solve the above problems. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1-Figure 3 The utility model provides an embodiment of a mobile platform for steam turbine maintenance of a thermal power plant parts storage mechanism, comprising a frame 1, the frame 1 serving as the core frame of the entire mobile platform to ensure that the platform has sufficient carrying capacity during use, a push-pull handle 2 fixedly connected to one side of the frame 1, and the user can conveniently operate the movement of the platform, a support platform 3 fixedly connected to the inside of the frame 1, a storage platform 10 fixedly connected to the inside of the frame 1 for storing various parts required for maintenance, a baffle 4 fixedly connected to one side of the storage platform 10, the function of the baffle 4 is to prevent the stored parts from falling during transportation, and to ensure the safety of the parts storage, a lifting assembly is provided on the top of the support platform 3, the lifting assembly is used to adjust the height of the platform, a moving assembly is provided at the bottom of the frame 1, and the moving assembly is used to move the platform;

[0034] The lifting assembly includes a cylinder 5 and a push rod 6. The bottom of the cylinder 5 is fixedly connected to the top of the support platform 3, and the bottom end of the push rod 6 is fixedly connected to the output end of the cylinder 5. The push rod 6 is slidably connected to the inside of the storage platform 10. The structural design of the sliding connection of the push rod 6 ensures that it can operate stably during the lifting process to avoid jamming. The top of the push rod 6 is fixedly connected to the maintenance platform 7, and the side wall of the maintenance platform 7 is fixedly connected to the sliding sleeve 8. The sliding sleeve 8 is used to accommodate the guide column 9 and ensure that the maintenance platform 7 remains stable during the lifting process. The top of the storage platform 10 is fixedly connected to the guide column 9. The function of the guide column 9 is to provide a stable guide path for the sliding sleeve 8, which can effectively reduce lateral shaking during the lifting process of the maintenance platform 7. The sliding sleeve 8 is slidably connected to the outer wall of the guide column 9. The top of the storage platform 10 is fixedly connected to a partition plate 11, which is used to divide the storage platform 10 into multiple areas for classified storage of different maintenance accessories.

[0035] Specifically, in the process of using the steam turbine maintenance mobile platform, the required accessories are first neatly placed on the storage table 10 inside the frame 1. In order to ensure effective classification and storage and retrieval of accessories, a plurality of partition plates 11 are provided in the storage table 10. Different types of accessories can be reasonably separated by these partition plates 11. When it is necessary to adjust the height of the maintenance table 7, the user can adjust it by operating the cylinder 5. The output end of the cylinder 5 is connected to the push rod 6. The cylinder 5 drives the push rod 6 to slide smoothly along the track inside the storage table 10. During the sliding process, the push rod 6 is driven by the force to drive the maintenance table 7 connected to its top end to move up and down, thereby completing the adjustment of the height of the maintenance table 7. During the height adjustment process, the maintenance table 7 cooperates with the guide column 9 through the sliding sleeve 8. When the push rod 6 drives the maintenance table 7 to move up and down, the side wall of the maintenance table 7 is connected to the sliding sleeve 8, and the sliding sleeve 8 can slide smoothly on the outer wall of the guide column 9. The guide column 9 plays a guiding role, so that the movement of the sliding sleeve 8 and the maintenance platform 7 always remains stable, avoiding the maintenance platform 7 from tilting or shifting during the height adjustment process, and achieving the effect of adjusting the height of the maintenance platform 7 according to maintenance requirements.

[0036] Reference Figure 3 and Figure 4 The moving assembly includes a rectangular array of fixed plates 12 and moving wheels 13. The top of the fixed plate 12 is fixedly connected to the bottom of the frame 1 in a rectangular array to play a supporting and bearing role. The moving wheels 13 are arranged at the bottom of the fixed plate 12 in a rectangular array to achieve the translation or movement of the system. A fixed column 14 is fixedly connected to the bottom of the frame 1. A hollow column 15 is fixedly connected to the bottom end of the fixed column 14. A sliding column 16 is slidably connected to the inside of the hollow column 15, so that the sliding column 16 can slide freely in the inner cavity of the hollow column 15. The outer wall of the hollow column 15 is rotatably connected to a connecting plate 17. The function of the connecting plate 17 is to connect the hollow column 15 to the L-shaped rod 19. A collar 18 is fixedly connected to one side of the connecting plate 17. The function of the collar 18 is to provide additional support and prevent the components from slipping or dislocating. One side of the connecting plate 17 is rotatably connected to the L-shaped rod 19. The design of the L-shaped rod 19 enables it to rotate within a certain range around the connection point. The L-shaped rod 19 is rotatably connected to a connecting column 21 inside, and one end of the connecting column 21 is fixedly connected to the outer wall of the sliding column 16. When the L-shaped rod 19 rotates, it can drive the sliding column 16 to slide. A clamping plate 20 is fixedly connected to one side of the L-shaped rod 19. The function of the clamping plate 20 is to provide a limiting effect on the sliding or rotating parts to ensure that the device does not move excessively or be damaged during operation. The bottom end of the sliding column 16 is fixedly connected to a base 22. The function of the base 22 is to stabilize the bottom of the sliding column 16 and provide supporting force at the same time. A spring 23 is provided inside the hollow column 15. The top end of the spring 23 is fixedly connected to the inside of the hollow column 15, and the bottom end of the spring 23 is fixedly connected to the inside of the sliding column 16. The main function of the spring 23 is to provide rebound force, so that the sliding column 16 can return to its original position when compressed by external force.

[0037] Specifically, when the platform needs to be moved or fixed, the operation can be achieved by pulling the collar 18. When the collar 18 is pulled, it will be forced to drive the connecting plate 17 to rotate, and the rotation of the connecting plate 17 will in turn drive the L-shaped rod 19 on one side to rotate. The other end of the L-shaped rod 19 is connected to the card plate 20. When the L-shaped rod 19 rotates, the card plate 20 moves along its connection direction. At the same time, the L-shaped rod 19 will also drive the connecting column 21 to move. After the connecting column 21 is forced, it pushes the sliding column 16 into the hollow column 15. When the sliding column 16 is forced, the spring 23 in the hollow column 15 is compressed, thereby generating a certain rebound force. In addition, the movement of the sliding column 16 will also drive the base 22 connected at the bottom to lift upward until the base 22 leaves the ground, thereby allowing the moving wheel 13 at the bottom of the frame 1 to touch the ground, ensuring that the frame 1 has better support and stability during movement. At this time, the ring 18 is inserted into the outer wall of the card plate 20 to complete the fixation, preventing the platform from accidentally shifting during movement or use. Next, by pushing the push-pull handle 2 on one side of the frame 1, the operator can flexibly move the frame 1 through the moving wheel 13 at the bottom to reach the desired position. When the frame 1 is moved to the appropriate position, it is only necessary to rotate the ring 18 out from the outer wall of the card plate 20. At this time, the reverse rebound effect of the spring 23 releases the previous compression force, causing the slide post 16 to return to its original position and drive the base 22 to fall back to the ground, thereby providing stable support for the frame 1. At the same time, due to the upward lifting of the slide post 16, the moving wheel 13 will be lifted, preventing the moving wheel 13 from continuing to contact the ground when fixed, thereby ensuring the stability of the frame 1.

[0038] Working principle: When using the mobile platform for steam turbine maintenance, first place the required accessories on top of the storage table 10 inside the frame 1, and different types of accessories can be separated by the partition plate 11. When the height of the maintenance table 7 needs to be adjusted, the push rod 6 can be driven to move by the output end of the cylinder 5, so that the push rod 6 slides inside the storage table 10. At the same time, the push rod 6 will be forced to drive the maintenance table 7 connected to the top to move, and the maintenance table 7 is forced to drive the sliding sleeve 8 connected to the side wall to slide up and down on the outer wall of the guide column 9, thereby adjusting the height of the maintenance table 7, thereby achieving the effect of adjusting the height of the maintenance table 7 according to maintenance needs. When the platform needs to be moved or fixed, the ring 18 can be pulled to force the connecting plate 17 to rotate, and the connecting plate 17 is forced to drive the L-shaped rod 19 on one side to rotate, and the L-shaped rod 19 is forced to drive the card plate 20 connected on one side to move. The spring 23 is then released to unload the force and rebound, thereby pushing the slide post 16 to reset, so that the slide post 16 drives the base 22 to fall on the ground for support, and at the same time lifts the moving wheel 13 upward, thereby achieving the effect of effectively fixing the frame 1 in place during maintenance.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
