[0002] The processing of the steel structure surface refers to a series of treatment operations on the steel surface during the manufacturing and maintenance of steel structures to improve the adhesion of coatings, enhance corrosion resistance, and extend the service life of the structure. These treatment operations may include processes such as rust removal, grinding, shot blasting, sandblasting, cleaning, and coating. At the same time, scraping the steel structure surface coating is also an important step in the painting process, aiming to ensure the uniformity and appropriate thickness of the coating. By scraping, excess paint can be removed, avoiding paint accumulation and sagging, thereby improving the appearance quality and protective performance of the coating.

However, after the scraping is completed, there is still a lot of paint on the scraper, and the device itself cannot be quickly cleaned, which is likely to affect the next use. Therefore, those skilled in the art have provided a scraping device for steel structure surface coatings to solve the problems raised in the above background technique. Content of the Utility Model

Detailed implementation manners

[0022] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following further details the present invention in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] Please refer to Figures 1 to 5, the utility model provides a scraping device for the surface coating of steel structures, which includes a fixing frame 1. The upper surface of the fixing frame 1 is fixedly connected with a support frame 2. Both side surfaces of the support frame 2 are fixedly connected with limiting frames 13. The inner wall of each limiting frame 13 is slidably connected with a bolt 14. The inner top wall of each limiting frame 13 is fixedly connected with a spring 15. The bottom end of each spring 15 is fixedly connected with the outer surface of the bolt 14. The inner wall of the support frame 2 is slidably connected with a cleaning frame 16. Both side surfaces of the cleaning frame 16 are fixedly connected with limiting blocks 17. The outer surface of each limiting block 17 is slidably connected with the inner wall of the support frame 2. The front and back surfaces of the cleaning frame 16 are both fixedly connected with fixing frames 18. The inner wall of the cleaning frame 16 is slidably connected with a cleaning block 19. The front and back surfaces of the cleaning block 19 are both fixedly connected with moving blocks 21. The outer surface of each moving block 21 is slidably connected with the inner wall of the cleaning frame 16. The outer surface of each moving block 21 is also slidably connected with the inner wall of the fixing frame 18. The inner wall of one of the fixing frames 18 is fixedly connected with a forward and reverse motor 20. The output end of the power of the forward and reverse motor 20 is fixedly connected with a threaded rod 22. The outer surface of the threaded rod 22 is threadedly connected with the inner wall of one of the moving blocks 21.

[0024] By setting the cleaning block 19, since the cleaning block 19 has a certain curvature, it can fit the surface of the scraper body 12 during cleaning, which can further improve the cleaning efficiency of the cleaning block 19.

[0025] Furthermore, the bottom surface of the fixing frame 1 is fixedly connected with four support legs 3. The bottom surface of each support leg 3 is fixedly connected with a base 4. By setting the support legs 3 and the bases 4, it can provide a good supporting effect for the device, enabling it to work stably.

[0026] Furthermore, two rotating shafts 7 are rotatably connected to the inner wall of the fixing frame 1. A conveyor belt 8 is rotatably connected to the outer surfaces of the two rotating shafts 7. By setting the rotating shafts 7 and the conveyor belt 8, it can facilitate the movement of the steel structure on the surface, improving the continuity during the scraping of the surface coating of the steel structure.

[0027] Furthermore, the left end of one of the rotating shafts 7 is fixedly connected with a rotating motor 6. The outer surface of the rotating motor 6 is fixedly connected with the left side surface of the fixing frame 1. By setting the rotating motor 6, it can provide the power required for the transportation of the steel structure, thus quickly driving the steel structure to move.

[0028] Furthermore, the outer surface of the rotating motor 6 is fixedly connected with a reinforcing frame 5. The right side surface of the reinforcing frame 5 is fixedly connected with the left side surface of the fixing frame 1. By setting the reinforcing frame 5, it can further increase the stability of the rotating motor 6 during operation and avoid jitter.

[0029] Furthermore, two reinforcing blocks 10 are fixedly connected to both the front and back of the support frame 2, and the bottom surface of each reinforcing block 10 is fixedly connected to the upper surface of the fixing frame 1. By providing the reinforcing blocks 10, the connection effect between the support frame 2 and the fixing frame 1 can be further enhanced, enabling them to be connected more firmly.

[0030] Furthermore, two multi-stage electric telescopic rods 11 are fixedly connected to the inner top wall of the support frame 2, and the telescopic ends of the two multi-stage electric telescopic rods 11 are commonly fixedly connected to a scraper body 12. By providing the multi-stage electric telescopic rods 11 and the scraper body 12, the multi-stage electric telescopic rods 11 can drive the scraper body 12 to move up and down, and at the same time, the scraper body 12 is convenient for scraping materials.

[0031] Furthermore, a pull rod 9 is commonly fixedly connected to the upper surfaces of the two bolts 14, and the bottom surface of the pull rod 9 is in contact with the upper surface of the support frame 2. By providing the pull rod 9, it is convenient for the staff to simultaneously pull the two bolts 14 to move up and down through the pull rod 9, further improving the work efficiency of the staff.

[0032] Working principle: When in use, first, the staff transports the device to a suitable working position, and then turns on the power supplies of the rotating motor 6, the forward and reverse motor 20, and the multi-stage electric telescopic rod 11. When it is necessary to scrape the coating on the surface of the steel structure, the staff places the steel structure with the coating completed on the conveyor belt 8, and then turns on the multi-stage electric telescopic rod 11. After the multi-stage electric telescopic rod 11 is turned on, it can push the scraper body 12 below to move. Until it moves to a suitable height, then turn on the rotating motor 6. After the rotating motor 6 is turned on, it can drive the rotating shaft 7 to rotate. The rotating shaft 7 can drive the conveyor belt 8 on the surface to rotate, so as to drive the steel structure on the surface to move. The coating on the surface of the steel structure contacts the scraper body 12 to realize the function of scraping the material, thereby increasing the uniformity and flatness of the coating on the surface of the steel structure. When it is necessary to clean the scraper body 12, the staff controls the scraper body 12 to rise through the multi-stage electric telescopic rod 11, and then pulls up the two pins 14 through the pull rod 9. When the pins 14 move upward, they can squeeze the spring 15. Subsequently, the cleaning frame 16 is pulled to the working position through the limit block 17. The staff releases the pins 14 so that the pins 14 can be reset under the action of the spring 15, thereby being able to limit the limit block 17 through the pins 14. Then turn on the multi-stage electric telescopic rod 11 again so that the bottom of the scraper body 12 can enter the cleaning frame 16. Subsequently, the forward and reverse motor 20 can be turned on. The rotation of the forward and reverse motor 20 can drive the threaded rod 22 to rotate. Under the action of the rotation of the threaded rod 22, the moving block 21 will be driven to move. The movement of the moving block 21 can drive the cleaning block 19 to move. Since the cleaning block 19 has a certain inclination angle and can fit with the scraper body 12, the coating on the surface of the scraper body 12 can be cleaned when the cleaning block 19 moves. Finally, when the scraping work is completed, the staff collects the coating residues inside the cleaning frame 16 and on the surface of the cleaning block 19.
