However, these manual rust removal methods are limited by worker strength and skill levels, and processing a single pipe is time-consuming, making it difficult to meet the needs of large-scale operations. Furthermore, manual rust removal is prone to overlooking areas or over-grinding, resulting in uneven surface treatment of the pipes and affecting their subsequent performance. Therefore, these methods suffer from low rust removal efficiency and inconsistent quality. Utility Model Content

The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail below.

[0021] This application provides an intelligent rust removal and cleaning device for pipes, employing the following technical solution: Reference Figure 1 The cleaning equipment includes a base support 1, a rolling frame 2, a traveling frame 3, an outer wall rust-removing wheel 4, and an inner wall rust-removing wheel 5. The base support 1 has a cuboid frame structure and includes a pair of parallel guide rails 11 and several spaced crossbars 12. The length of the guide rails 11 extends along a first direction, which is designated as the X direction. The axial extension direction of the pipe placed on the base support 1 is also the first direction. The crossbars 12 are installed between the parallel guide rails 11 and extend along a second direction, which is designated as the Y direction and is perpendicular to the first direction.

[0022] Reference Figure 1 Multiple rolling frames 2 are installed at intervals along the first direction. Each rolling frame 2 includes two rollers 21, which are symmetrically mounted on the same crossbar 12. The rollers 21 are driven to rotate by a drive source such as a motor. When the pipe is placed on the base support 1, the pipe is located between the two rollers 21, and the periphery of the pipe is in contact with the periphery of both rollers 21. The center of the pipe's axis and the center of the axis of the two rollers 21 form an isosceles triangle. Under the rotation of the rollers 21, the pipe is driven to rotate along its own axis.

[0023] Reference Figure 1 The walking frame 3 includes a frame 30 and a walking wheel 31. The frame 30 is a cuboid frame. The walking wheel 31 is installed at the bottom of the cuboid frame. The walking wheel 31 is driven to rotate by a servo motor. The walking wheel 31 cooperates with the guide rail 11. The walking wheel 31 slides back and forth along the top surface of the guide rail 11. The sliding distance is controlled by the servo motor.

[0024] Reference Figure 1 and Figure 2 Both the outer wall rust-removing wheel 4 and the inner wall rust-removing wheel 5 are steel wire wheels, which grind the rusted surface through rotational friction. The outer wall rust-removing wheel 4 is suspended on the frame 30 of the traveling frame 3. The outer circumference of the outer wall rust-removing wheel 4 abuts against the outer wall of the pipe. The rotation direction of the outer wall rust-removing wheel 4 is opposite to the rotation direction of the pipe, grinding and removing rust from the outer wall of the pipe. At the same time, the outer wall rust-removing wheel 4 moves back and forth along the axis of the pipe with the traveling wheel 31, grinding and removing rust from all areas of the outer surface of the pipe. The inner wall rust-removing wheel 5 is rotatably mounted on the crossbar 12. When it is necessary to remove rust from the inner wall of the pipe, the inner wall rust-removing wheel 5 extends into the inner cavity of the pipe. The inner wall rust-removing wheel 5 contacts and rubs against the inner wall of the pipe, grinding and removing rust from the inner surface area of ​​the pipe.

[0025] An electronic control unit (not shown in the figure) is mounted on the traveling frame 3. The electronic control unit is an MCU chip and is electrically connected to the drive motor 6 that controls the traveling wheels 31. The electronic control unit controls the traveling speed and distance of the traveling wheels 31, thereby making the rust removal process more uniform and comprehensive. Furthermore, the electronic control unit is also electrically connected to the motor of the rollers 21 to adjust the rotation speed of the rollers 21, thereby controlling the rotation speed of the pipe. This ensures that the sliding speed of the traveling frame 3 matches the rotation speed of the pipe, thus improving the uniformity of rust removal on the outer wall of the pipe.

[0026] In the preferred embodiment of this application, reference is made to Figure 1 and Figure 3 Two suspension rods 32 are rotatably mounted on the inner wall of the frame 30 of the traveling frame 3. One end of each suspension rod 32 is hinged to the same point on the top surface inside the frame 30, while the other end is free. The two suspension rods 32 can be separated and self-locked by gear engagement or cylinder extension / retraction, resulting in a certain angle between the two suspension rods 32. Two outer wall rust removal wheels 4 are also correspondingly provided, one installed at the end of each suspension rod 32 away from the hinge point. The two outer wall rust removal wheels 4 are symmetrically arranged and located on both sides of the pipe, simultaneously grinding and removing rust from both sides of the pipe, thereby improving rust removal efficiency.

[0027] Furthermore, referring to Figure 3 The included angle between the two suspension rods 32 is set and fixed by the electronic control unit, and the included angle ranges from 15° to 60°. By adjusting the included angle between the two suspension rods 32, the contact pressure between the outer wall rust removal wheel 4 and the outer wall of the pipe can be dynamically adjusted, so that the outer wall rust removal wheel 4 fits tightly against the surface of the pipe, thereby adapting to the complex rust morphology of the outer surface of the pipe and meeting different rust removal needs.

[0028] In the preferred embodiment of this application, reference is made to Figure 1 and Figure 2 A drive motor 6 is fixedly mounted on the crossbar 12. The drive motor 6 is electrically connected to the electronic control unit, which adjusts the speed of the drive motor 6. The output shaft of the drive motor 6 faces the pipe, and a telescopic rod 7 is connected to the output shaft. The telescopic rod 7 consists of at least two round rods connected by a cylinder. The telescopic rod 7 extends into the inner cavity of the pipe, and the inner wall rust-removing wheel 5 is sleeved on the end of the telescopic rod 7 away from the drive motor 6. When rust removal is required on the inner wall of the pipe, the drive motor 6 drives the inner wall rust-removing wheel 5 to rotate through the telescopic rod 7, making it contact and grind the inner wall of the pipe. The telescopic rod 7 moves back and forth along the axis of the pipe according to the processing situation, performing full-area rust removal on the inner wall of the pipe, thereby improving the rust removal efficiency and quality of the inner wall of the pipe.

[0029] In the preferred embodiment of this application, reference is made to Figure 1 and Figure 3 The traveling wheel 31 slides on the top surface of the guide rail 11. The traveling frame 3 extends downward toward the bottom end of the traveling wheel 31. An auxiliary wheel 33 is rotatably installed at the bottom end of the traveling frame 3. The auxiliary wheel 33 is slidably connected to the bottom surface of the guide rail 11. The traveling wheel 31 and the auxiliary wheel 33 cooperate to clamp and slide at the upper and lower ends of the guide rail 11, thereby improving the stability of the traveling frame 3's sliding and helping to improve the rust removal quality of the pipe surface.

[0030] In a preferred embodiment of this application, a plurality of threaded holes are equidistantly provided on the crossbar 12 along the second direction. The rollers 21 are detachably mounted on the crossbar 12 by screws. The rollers 21 are fastened to the threaded holes located in different locations, which can adjust the distance between the two rollers 21, thereby increasing the flexibility of the roller 21 frame and adapting to pipes of different diameters.

[0031] The experimental principle of this embodiment is as follows: When rust removal is required on the pipe, the pipe is placed on the rolling frame 2, which supports and drives the pipe to rotate. The traveling frame 3 drives the outer wall rust removal wheel 4 to abut against the outer surface of the pipe through the suspension rod 32. The traveling frame 3 reciprocates along the guide rail 11 to polish all areas of the outer surface of the pipe. At the same time, the drive motor 6 drives the inner wall rust removal wheel 5 to rotate, and the telescopic rod 7 extends into the inner cavity of the pipe. The inner wall rust removal wheel 5 abuts against the inner surface of the pipe, and the inner wall of the pipe is simultaneously derusted. This not only shortens the time for rust removal of a single pipe and improves work efficiency, but also balances the rotation speed parameters between the traveling frame 3 and the roller 21 through the electronic control unit, flexibly adapting to different rust morphologies on the surface of the pipe, thus improving the quality of rust removal on the surface of the pipe.

Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
