Technical Field

[0001] This utility model relates to the field of stainless steel pipe processing technology, specifically a rust removal device for processing the inner wall of large-diameter stainless steel pipes. Background Technology

[0002] In the production, processing, and maintenance of large-diameter stainless steel pipes, rust removal from the inner wall is a crucial process. If rust is present on the inner wall of a stainless steel pipe, it will not only affect the appearance quality of the pipe, but also have a serious negative impact on its performance. For example, rust will reduce the corrosion resistance of the pipe and shorten its service life. When transporting fluid media, rust may fall off and mix into the media, affecting the purity of the media, and even damaging subsequent process equipment.

[0003] A search revealed that CN211760294U discloses a rust removal device for the inner wall of steel pipes, comprising a base, a vertical plate, and a slide rail. The vertical plate is mounted on one end of the top of the base via a mounting groove, and the slide rail is welded to the other end of the top of the base. A mounting seat is welded between the vertical plate and the slide rail, and a hydraulic cylinder is bolted to the top of the mounting seat. A groove is formed at the top of the slide rail, and a slider is fitted inside the groove. A vertical rod is welded to the top of the slider, and a mounting plate is welded to the top of the vertical rod. A rotating motor is bolted to the top of the mounting plate, and the power output end of the rotating motor is connected to a rotating shaft. This utility model can easily and quickly clamp and fix steel pipes, facilitate the replacement of the cleaning head, and easily move the cleaning head horizontally along the inner wall of the steel pipe, thereby improving the cleaning effect. It has good shock absorption and stable operation, making it suitable for widespread promotion and use.

[0004] In the aforementioned patent, the brush cleaning device adopts an integrated design. When the brush bristles are worn or damaged, the replacement process is cumbersome and complicated, requiring a lot of time and manpower, which not only increases production costs but also affects production efficiency.

[0016] 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.

[0017] Example 1 Please see Figures 1 to 5 This utility model provides a technical solution: a rust removal device for processing the inner wall of a large-diameter stainless steel pipe, including a processing device 1, and further including a rust removal disassembly and assembly component 2; The rust removal assembly 2 is set on the top of the processing device 1. The rust removal assembly 2 includes: mounting base 21, fixing cylinder 29 and cleaning brush body 214. The cleaning brush body 214 performs rust removal treatment on the inner wall of the large-diameter stainless steel pipe. A rotating gear 22 is connected to one side of the mounting base 21. A guide rod 23 is installed inside the mounting base 21. A spring 24 is installed on one side of the mounting base 21, outside the guide rod 23. A slide 25 is connected to the outside of the guide rod 23. One end of the spring 24 is connected to the slide 25. A connecting rod 26 is installed on one side of the slide 25. A rack 27 is installed on one side of the connecting rod 26. The rack 27 meshes with the rotating gear 22. A connecting bracket 28 is installed at one end of the connecting rod 26. The outer side of the mounting base 21 is connected to the fixed cylinder 29. The connection includes several sets of connecting plates 210 inside the fixed cylinder 29, with one end of each connecting plate 210 connected to a connecting plate 211. The connection frame 28 has several sets of connecting plates 212 outside, with one end of each connecting plate 212 connected to the connecting plate 211. Each connecting plate 211 has a positioning plate 213 installed on one side. The fixed cylinder 29 has a connecting seat 215 inside, with several sets of positioning grooves 216 on the outside of the connecting seat 215. The positioning grooves 216 are adapted to the positioning plates 213. The guide rod 23 guides the slide 25. By rotating the rotating tooth 22, the rack 27 can be moved, thereby realizing the subsequent disassembly and assembly of the cleaning brush body 214. The cleaning brush body 214 is installed with the connecting seat 215.

[0018] The processing device 1 is the existing structure disclosed in CN211760294U, which includes: a base, a vertical plate, a U-shaped fixing sleeve, an adjusting bolt, a connecting block, a crossbar, a bushing, a hydraulic cylinder, a mounting base, a slide rail, a vertical rod, a mounting plate, a rotating motor, a push rod, a threaded hole, a clamping block, a slider, a slide groove, a countersunk screw, and rubber feet; the specific implementation method will not be described in detail here. When it is necessary to connect the cleaning brush body 214 to the fixed cylinder 29, the rotating tooth 22 is rotated manually or by other driving methods. Since the rack 27 meshes with the rotating tooth 22, the rotation of the rotating tooth 22 will drive the rack 27 to move. The rack 27 drives the connecting rod 26 to move. The connecting rod 26 drives the slide 25 to move along the guide rod 23, while compressing the spring 24. The movement of the connecting rod 26 drives the connecting frame 28 to move. The connecting frame 28 pulls the connecting plate 211 through the connecting plate 3 212, causing the connecting plate 211 to drive the positioning plate 213 to move. After the multiple connecting plates 211 are expanded outward, the connecting seat 215 is placed inside the fixed cylinder 29. When the positioning... When the plate 213 corresponds to the position of the positioning groove 216, release the rotating tooth 22. At this time, the spring 24 drives the slide 25 and the connecting rod 26 to reset, and the positioning plate 213 can be inserted into the positioning groove 216 to realize the fixed connection between the connecting seat 215 and the fixed cylinder 29, thereby completing the installation of the cleaning brush body 214. When it is necessary to disassemble the cleaning brush body 214, the same operation is performed. Rotate the rotating tooth 22 until the connecting plate 211 drives the positioning plate 213 to exit from the positioning groove 216. At this time, the connecting seat 215 along with the cleaning brush body 214 can be easily taken out from the inside of the fixed cylinder 29, completing the disassembly of the cleaning brush body 214. After the cleaning brush body 214 is installed, the processing device 1 is started. The processing device 1 drives the rust removal assembly 2 to move as a whole, so that the cleaning brush body 214 enters the interior of the large-diameter stainless steel pipe. The cleaning brush body 214 contacts the inner wall of the stainless steel pipe and rubs the inner wall through rotation and reciprocating motion, thereby removing the rust from the inner wall and achieving rust removal treatment of the inner wall of the large-diameter stainless steel pipe.

[0019] Example 2 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the fixing cylinder 29 is made of transparent material, which allows the user to clearly see whether the positioning plate 213 is accurately inserted into the positioning groove 216 during the installation process.
