Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-4 The present invention provides an embodiment of an external wall cleaning device for the production of galvanized steel pipes, comprising a frame 1, with four corners at the bottom of the frame 1 fixedly connected to support legs 14, support frames 2 fixedly connected to the left and right sides at the bottom of the frame 1, a steel pipe body 3 disposed inside the frame 1, and a drive structure for adjusting the height of the movable limiting plate 4 disposed at the top of the frame 1.
[0026] The drive structure includes a threaded sleeve 5, a threaded rod 7, and a servo motor 11. A protective shell 30 is provided at the top of the frame 1. Mounting brackets 6 are fixedly connected to the left and right sides between the protective shell 30 and the frame 1. The threaded rod 7 is movably connected inside the mounting bracket 6. A drive roller 31 is fixedly connected to the top of the threaded rod 7. A drive belt 8 is provided inside the protective shell 30. A servo motor 11 is installed on the right side of the top of the protective shell 30. Movable limiting plates 4 are provided on the left and right sides inside the frame 1. A threaded sleeve 5 is fixedly connected to the top of the movable limiting plate 4. A limiting clamp 13 is fixedly connected to the side of the threaded sleeve 5 near the outside. Limiting grooves 12 are opened on the left and right sides of the top of the frame 1. Transparent protective covers are provided at the front and rear ends of the frame 1.
[0027] The support frame 2 and the movable limiting plate 4 are respectively set on the left and right sides of the upper and lower ends of the steel pipe body 3. The drive roller 31 is set on the left and right sides inside the drive belt 8. The threaded sleeve 5 is set on the bottom end outside the threaded rod 7. The limiting clamp 13 slides up and down inside the limiting groove 12. The upper and lower ends of the frame 1 are equipped with hydraulic cylinders 9. The drive motor 17 is installed at the end of the hydraulic cylinder 9 near the middle. The output end of the drive motor 17 is fixedly connected to the rotating shaft 16. The grinding disc 15 is installed at the end of the rotating shaft 16 near the middle.
[0028] Specifically, such as Figure 1 and Figure 4 As shown, place the steel pipe body 3 to be cleaned on the top of the support frame 2, and make the area to be cleaned contact the grinding disc 15. After placing it, start the servo motor 11. The servo motor 11 drives the two sets of threaded rods 7 to rotate simultaneously through the drive roller 31 and the drive belt 8. When the threaded rods 7 rotate, the threaded sleeve 5 can drive the movable limit plate 4 to descend, so that the movable limit plate 4 limits and fixes the steel pipe body 3, preventing the steel pipe body 3 from accidentally sliding and affecting the cleaning effect when the grinding disc 15 grinds the steel pipe body 3.
[0029] A housing 18 is located on the left side of the bottom of the frame 1. An exhaust fan 23 is installed on the left side inside the housing 18. The input and output ends of the exhaust fan 23 are respectively fixedly connected to pipes 29. A filter screen 28 is installed in the middle of the housing 18. A storage drawer 27 is installed at the bottom right side of the housing 18. A connecting pipe 26 passes through the top right side of the housing 18. A branch pipe 24 is fixedly connected to the top of the connecting pipe 26. A dust suction port 25 is installed at the top of the branch pipe 24. The right side of the pipe 29 is located on the left side of the filter screen 28. The storage drawer 27 is located at the bottom of the connecting pipe 26. The branch pipe 24 is located at the top inside the frame 1. Multiple sets of dust suction ports 25 are provided.
[0030] Specifically, such as Figure 1 and Figure 3 As shown, when the grinding disc 15 grinds the steel pipe body 3, it will generate debris. The exhaust fan 23 is started. The exhaust fan 23 uses pipe 29 and branch pipe 24 to absorb and collect the debris, preventing the debris from polluting the environment. The transparent protective cover can prevent the debris from splashing and injuring the staff. The absorbed debris will fall into the storage drawer 27.
[0031] A fixing rod 10 is fixedly connected to the right side of the upper and lower ends inside the frame 1. A cleaning frame 19 is fixedly connected to the side of the fixing rod 10 near the middle. A fixing plate 21 is provided on the inner side wall of the cleaning frame 19. A cleaning sponge 20 is fixedly connected to the inner side wall of the fixing plate 21. Baffles 22 are movably hinged on the left and right sides of the cleaning frame 19. The baffles 22 are provided on the left and right sides of the fixing plate 21. The fixing plate 21 is installed on the inner side wall of the cleaning frame 19 through the baffles 22.
[0032] Specifically, such as Figure 1 and Figure 2 As shown, the cleaning sponge 20 can further clean the outer wall of the steel pipe body 3 and wipe away dust and oil stains. When the cleaning sponge 20 needs to be disassembled and replaced, rotate the baffle 22 to make the fixing plate 21 lose its fixation. After the fixing plate 21 loses its fixation, the cleaning sponge 20 can be disassembled and replaced with a new cleaning sponge 20.
[0033] Working principle: In use, the steel pipe body 3 to be cleaned is placed on top of the support frame 2, ensuring the area to be cleaned is in contact with the grinding disc 15. After placement, the servo motor 11 is started. The servo motor 11 drives two sets of threaded rods 7 to rotate simultaneously via the drive roller 31 and drive belt 8. When the threaded rods 7 rotate, the threaded sleeve 5 drives the movable limiting plate 4 to descend, thus limiting and fixing the steel pipe body 3 and preventing accidental slippage of the steel pipe body 3 during grinding by the grinding disc 15, which would affect the cleaning effect. When the grinding disc 15 grinds the steel pipe body 3, it generates debris. The exhaust fan 23 is then started to remove the debris. The fan 23 collects debris by adsorbing it through the pipe 29 and the branch pipe 24, preventing debris from polluting the environment. The transparent protective cover can prevent debris from splashing and injuring the staff. The adsorbed debris will fall into the storage drawer 27. When the debris needs to be disposed of, the storage drawer 27 can be pulled out of the shell 18. The cleaning sponge 20 can further clean the outer wall of the steel pipe body 3 and wipe away dust and oil. When the cleaning sponge 20 needs to be disassembled and replaced, rotate the baffle 22 to make the fixing plate 21 lose its fixation. After the fixing plate 21 loses its fixation, the cleaning sponge 20 can be disassembled and replaced with a new cleaning sponge 20.
[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
