Description

Technical Field

[0001] This application relates to the field of copper tube production technology, and in particular to a copper tube cleaning and rust prevention detection device and its rust prevention detection process. Background Technology

[0002] Copper pipes are widely used in air conditioning, heat exchange, and fluid transportation due to their excellent thermal conductivity, corrosion resistance, and processing properties. During the manufacturing and use of copper pipes, rolling oil, scale, dust, and other contaminants can easily remain on the inner wall during processing, heat treatment, storage, and transportation. If not removed, these contaminants will affect the quality of subsequent welding and coating, and accelerate localized corrosion during use. Furthermore, rust may develop on the inner wall of the copper pipe over long-term operation, leading to decreased heat transfer efficiency, media contamination, and even pipe leaks. Therefore, cleaning the inner wall of the copper pipe to remove contaminants, testing the rust removal effect to verify the cleaning quality, and finally applying an anti-rust paint to form a protective layer are crucial steps to ensure the quality of copper pipe products and extend their service life.

[0003] In existing technologies, the cleaning, inspection, and rust prevention of the inner wall of copper tubes are typically carried out sequentially using separate equipment. For example, the cleaning process often uses high-pressure water jet cleaners or chemical cleaning tanks to rinse the inner wall of the copper tube; the inspection process often uses endoscopes or industrial cameras, manually or mechanically driven, inserted into the tube to collect and interpret images; and the rust prevention process involves applying rust-preventive oil or paint to the inner wall through immersion or spraying equipment. These devices are arranged horizontally in a linear layout within the workshop, and the copper tubes need to be clamped, positioned, processed, and transferred sequentially between different devices, with material handover between processes relying on manual labor or robotic arms.

[0004] Regarding the aforementioned technologies, on the one hand, when the copper tube has a bent structure, existing equipment struggles to ensure the smooth passage and uniform action of cleaning nozzles, inspection heads, and rust-preventing nozzles inside the bend, easily creating blind spots in the bend and resulting in incomplete cleaning, inadequate inspection, or uneven coating. On the other hand, the horizontal linear arrangement of multiple machines occupies a large workshop area, and the multiple clamping of copper tubes between different machines not only increases auxiliary time between processes but also reduces production efficiency. Therefore, improvements are needed. Summary of the Invention

[0005] To address the aforementioned problems, this application provides a copper pipe cleaning and rust prevention detection device and its rust prevention detection process.

[0006] This application provides a copper pipe cleaning and rust prevention detection device and its rust prevention detection process, which adopts the following technical solution: A copper pipe cleaning and rust prevention testing device includes an operating table. A first mounting frame and a second mounting frame are fixedly mounted on the operating table. A first support platform, a second support platform, and a third support platform are fixedly mounted on the side of the second mounting frame near the first mounting frame. The first support platform is spaced apart and directly below the second support platform. The second support platform is spaced apart and directly below the third support platform. A cleaning nozzle for cleaning and drying the inner wall of the copper pipe is horizontally movably mounted on the first support platform. A testing head for detecting the rust removal effect on the inner wall of the copper pipe is horizontally movably mounted on the second support platform. A rust-preventive spraying device for spraying rust-preventive paint onto the inner wall of the copper pipe is horizontally movably mounted on the third support platform. The first mounting bracket has a lifting support platform on the side away from the second mounting bracket. A connecting structure is provided between the workstation support platform and the first support platform for fixing the workstation support platform to the first support platform. The operating platform is provided with a lifting component for horizontally moving and vertically lifting the workstation support platform so that the workstation support platform is fixedly connected to the first support platform, the second support platform and the third support platform respectively. The second support platform and the third support platform are set with the first support platform. The second mounting bracket is provided with a drive mechanism for driving the cleaning nozzle, the detection head and the rust prevention nozzle to move inside the bent copper pipe.

[0007] By adopting the above technical solution, the lifting assembly vertically lifts and horizontally moves the workstation support platform, allowing it to sequentially and permanently connect with the first, second, and third support platforms. After each connection, the corresponding cleaning nozzle, inspection head, or anti-rust nozzle is activated, and driven by the drive mechanism, it moves horizontally inside the bent copper tube, sequentially completing the cleaning and drying of the inner wall of the bent copper tube, the rust removal effect inspection, and the anti-rust paint spraying. This application integrates the three processes of cleaning, inspection, and spraying into the same device in terms of height. By switching and connecting the workstation support platform with the first, second, and third support platforms, the device's footprint is reduced, and the copper tube can be automatically processed through multiple processes in a single clamping state. This avoids the positioning errors and time losses caused by repeated clamping of the copper tube between different devices, thus improving processing efficiency.

[0008] Optionally, the connection structure includes a first socket post, a second socket post, and an electromagnet. The first socket post is fixedly disposed at the end of the workstation support platform, and the second socket post is fixedly disposed at the end of the first support platform. A first slot is formed at the end of the workstation support platform corresponding to the second socket post, and a second slot is formed at the end of the first support platform corresponding to the first socket post. The first socket post is inserted into the second slot, and the second socket post is inserted into the first slot. Multiple sets of electromagnets are provided, and the multiple sets of electromagnets are respectively embedded in the ends of the first socket post and the second socket post, as well as on the bottom walls of the first slot and the second slot.

[0009] By adopting the above technical solution, when the workstation support platform is moved by the lifting assembly to a predetermined position that aligns with the first, second, or third support platform, the first socket at the end of the workstation support platform inserts into the second socket at the end of the corresponding first, second, or third support platform, while simultaneously the second socket at the end of the corresponding first, second, or third support platform inserts into the first socket at the end of the workstation support platform, forming a bidirectional socket fit. Subsequently, multiple sets of electromagnets embedded in the ends of the first and second sockets and the bottom walls of the first and second sockets are simultaneously energized, generating magnetic attraction to firmly attract the workstation support platform to the corresponding first, second, or third support platform. This application utilizes the energization and attraction of multiple sets of electromagnets to achieve rapid locking after docking and rapid separation after power failure, meeting the requirement for rapid decoupling during process switching and improving the reliability of docking and switching efficiency.

[0010] Optionally, the lifting assembly includes a lifting platform, a first drive motor, a first lead screw, a column, a cylinder, a first limiting block, and a second limiting block. The first drive motor is fixedly mounted on the first mounting bracket, and the first lead screw is vertically fixedly mounted on the output shaft of the first drive motor. The lifting platform is lifted and lowered on the operating platform and threadedly connected to the first lead screw. Multiple sets of columns are provided, each set vertically fixedly mounted on the operating platform and slidably connected to the lifting platform. The cylinder is fixedly mounted on the lifting platform, and the first limiting block is fixedly mounted on the telescopic end of the cylinder for limiting the bent portion of the copper tube. The second limiting block is fixedly mounted on the lifting platform for limiting the straight portion of the copper tube. The cylinder drives the workstation support platform to move towards the first support platform by pushing the first limiting block.

[0011] By adopting the above technical solution, the first drive motor drives the first lead screw to rotate, causing the lifting platform to rise and fall vertically along multiple sets of columns, thereby adjusting the height of the workstation support platform in the vertical direction; subsequently, the cylinder pushes the first limiting block fixed to its telescopic end, and the first limiting block causes the workstation support platform to move horizontally in the direction of the first support platform, the second support platform, or the third support platform; this application realizes the lifting and lowering of the workstation support platform between different height workstations through the cooperation of the first drive motor and the first lead screw, reducing the floor space required by the device.

[0012] Optionally, the driving mechanism includes a first driving component, a second driving component, and a third driving component. The first driving component drives the cleaning nozzle to move, the second driving component drives the detection head to move, and the third driving component drives the anti-rust nozzle to move. The first driving component includes a second driving motor, a winding roller, a textured tube, a lead wire structure, and an anti-bending structure. The second driving motor is fixedly mounted on the side of the second mounting frame away from the first mounting frame. The winding roller is fixedly mounted on the output shaft of the second driving motor. One end of the textured tube is fixedly mounted on the winding roller. The cleaning nozzle is fixedly mounted on the end of the textured tube away from the winding roller. The lead wire structure is mounted on the side of the second mounting frame away from the first mounting frame to stably output the textured tube to the first support platform. The anti-bending structure is mounted on the second mounting frame to prevent the textured tube from stacking inside the bent copper tube.

[0013] By adopting the above technical solution, this application realizes the storage and release of long-distance textured tubes through the tube-winding roller, meeting the need for long-stroke movement of the cleaning nozzle within a limited space; the lead wire structure ensures the stability of the textured tube during the process of being transported from the second mounting frame to the first support platform, preventing the textured tube from getting tangled or stuck; the anti-bending structure plays a role after the textured tube extends into the copper tube, preventing the textured tube from stacking or bending due to gravity or resistance inside the bent copper tube, ensuring that the cleaning nozzle can smoothly reach the depth of the bent copper tube, realizing full-length inner wall cleaning, while avoiding cleaning blind spots or nozzle jamming caused by bending.

[0014] Optionally, the lead wire structure includes a third drive motor, a drive gear, a driven gear, a drive clamping roller, a driven clamping roller, and a lead wire tube. The third drive motor is fixedly mounted on the side of the second mounting frame away from the first mounting frame. The drive gear is fixedly mounted on the output shaft of the third drive motor. The drive clamping roller is fixedly mounted on the side of the drive gear away from the third drive motor. The driven gear is rotatably mounted directly below the drive gear, and the drive gear and the driven gear mesh with each other. The driven clamping roller is fixedly mounted on the side of the driven gear away from the third drive motor and is located directly below the drive clamping roller. The drive clamping roller and the driven clamping roller are used to clamp and transport the output textured tube. The lead wire tube is fixedly mounted on the side of the second mounting frame close to the first mounting frame and is used to guide the textured tube between the first mounting frame and the second mounting frame.

[0015] By adopting the above technical solution, the third drive motor drives the active gear to rotate, and the active gear drives the driven gear meshing with it to rotate in the opposite direction. The active clamping roller rotates synchronously with the active gear, and the driven clamping roller rotates synchronously with the driven gear. The active clamping roller and the driven clamping roller clamp the passing mesh tube and apply a conveying force, leading the mesh tube out from the winding roller and pushing it forward. After the mesh tube is output by the active clamping roller and the driven clamping roller, it enters the fixedly set guide tube, which guides it to the space between the first mounting frame and the second mounting frame. This avoids the mesh tube bending caused by uneven thrust when unwinding from the winding roller alone. The guide tube provides a guiding path for the mesh tube, ensuring that the mesh tube remains straight and directional accurately when crossing from the second mounting frame to the first support platform. This provides accurate initial alignment for subsequent entry into the copper tube, while reducing the swaying and friction of the mesh tube during the conveying process and improving the stability of the conveying.

[0016] Optionally, the anti-bending assembly includes a fourth drive motor, a second lead screw, a movable plate, a limiting rod, a snake-shaped tube, and an energized coil. The fourth drive motor is fixedly mounted on the side of the second mounting bracket away from the first mounting bracket. The second lead screw is rotatably mounted between the first and second mounting brackets and is fixedly connected to the output shaft of the fourth drive motor. The limiting rod is parallel to the second lead screw and fixedly mounted between the first and second mounting brackets. The movable plate is slidably mounted on the limiting rod and threadedly connected to the second lead screw. One end of the snake-shaped tube is fixed. The snake-bone tube is disposed on the side of the movable plate away from the second mounting bracket. When the snake-bone tube is located between the first mounting bracket and the second mounting bracket, the snake-bone tube is sleeved on the first support platform. When the snake-bone tube is located on the side of the first mounting bracket away from the second mounting bracket, the snake-bone tube is sleeved on the workstation support platform. The first mounting bracket has through holes for the snake-bone tube to pass through. The snake-bone tube includes multiple sets of snake-bone sections. Multiple sets of energizing coils are provided. The multiple sets of energizing coils are respectively fixedly disposed on the inner walls of the multiple sets of snake-bone sections. The inside of the mesh tube is filled with magnetorheological fluid.

[0017] By adopting the above technical solution, the fourth drive motor drives the second lead screw to rotate, causing the moving plate to move horizontally along the limit rod. The moving plate causes the snake tube to extend or retract synchronously. When the snake tube extends, it passes through the through holes on the first mounting bracket in sequence. When it is between the first mounting bracket and the second mounting bracket, it is sleeved on the first support platform. After passing through the first mounting bracket, it is sleeved on the workstation support platform and corresponds to the inside of the copper tube. During the process of the snake tube extending into the copper tube, multiple sets of energized coils set on the inner wall of each snake section are energized to generate a magnetic field that acts on the magnetorheological fluid inside the mesh tube, causing the magnetorheological fluid to change from a liquid state to a near-solid state, thereby increasing the bending stiffness of the mesh tube and realizing the real-time controllable adjustment of the rigidity of the mesh tube. When it needs to be extended, the energizer increases the rigidity to prevent stacking. When it needs to be retracted, the energizer is de-energized to restore flexibility for easy winding, thereby ensuring the uniformity and thoroughness of the cleaning of the entire inner wall.

[0018] Optionally, a support block is provided on the inner wall of the snake joint, and a ball bearing is provided on the support block. The first support platform, the second support platform, the third support platform and the workstation support platform are all provided with guide grooves, and the ball bearing is rotatably disposed in the guide grooves.

[0019] By adopting the above technical solution, when the snake-bone tube moves telescopically along the first support platform, second support platform, third support platform, or workstation support platform under the drive of the moving plate, the ball bearings on the support blocks on the inner wall of the snake-bone section are embedded in the guide grooves opened on the corresponding support platforms and roll along the guide grooves. Through the cooperation between the ball bearings and the guide grooves, the sliding friction between the snake-bone tube and the support platform is converted into rolling friction, which significantly reduces the frictional resistance during the telescopic process of the snake-bone tube, reduces the load on the drive mechanism, and improves the smoothness and response speed of the snake-bone tube movement. At the same time, the guide grooves guide and limit the ball bearings, ensuring that the snake-bone tube always remains coaxial with the workstation support platform, first support platform, second support platform, or third support platform during the movement, and preventing the snake-bone tube from radially deviating or twisting.

[0020] Optionally, the first support platform, the second support platform, the third support platform, the workstation support platform, the cleaning nozzle, the detection head, the rust prevention nozzle, and the driving structure are all arranged in two sets along the length of the operating platform for processing the "U"-shaped copper tube.

[0021] By adopting the above technical solution, two sets of equipment are set up, which not only enables the simultaneous processing of two sets of bent copper tubes, but also enables the processing of "U" shaped copper tubes. This improves the overall working efficiency of the device and also realizes the multi-functionality of the device.

[0022] This application also includes a copper pipe cleaning and rust prevention inspection process, comprising the following steps: S1: Place the copper tube on the workstation support platform and fix it by limiting and fixing it with the first limit block and the second limit block; start the lifting assembly to raise the workstation support platform to the same height as the first support platform, and then push the workstation support platform closer to the first support platform by the cylinder; complete the socket fit by the connecting structure, and achieve the fixed connection between the workstation support platform and the first support platform by energizing multiple sets of electromagnets; then reset the lifting assembly. S2: The first drive assembly drives the winding roller to release the textured tube. Guided by the active clamping roller, driven clamping roller and lead tube in the lead wire structure, the cleaning nozzle is horizontally sent into the copper tube. At the same time, the fourth drive motor in the anti-bending structure drives the second lead screw to move the moving plate. The snake-bone tube enters the copper tube synchronously with the cleaning nozzle. The energized coil on the inner wall of the snake-bone joint is energized to improve the solidity of the magnetorheological fluid inside the textured tube to prevent stacking. The cleaning nozzle moves and sprays cleaning fluid to complete the inner wall cleaning. Then it switches to high-pressure gas for drying. After completion, the cleaning nozzle retracts. S3: When the electromagnet is de-energized and disconnected, the lifting assembly adjusts the workstation support platform to the same height as the second support platform. The cylinder pushes and the connecting structure achieves a fixed docking with the second support platform, and then the lifting assembly resets. The second drive assembly is started to send the detection head horizontally into the copper tube from the second support platform. It moves along the inner wall to complete the rust removal effect detection. After the detection, the detection head retracts. S4: Disconnect again. The lifting component adjusts the workstation support platform to the same height as the third support platform. The cylinder pushes and the connecting structure achieves a fixed docking with the third support platform. Start the third drive component to send the anti-rust spray head horizontally from the third support platform into the copper pipe. Move along the inner wall and spray the anti-rust paint evenly. After completion, the anti-rust spray head retracts. S5: When the electromagnet is de-energized, the connection is released, and the lifting assembly drives the workstation support platform back to the initial position to remove the processed copper pipe.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. The workstation support platform is vertically raised and horizontally moved by a lifting assembly, so that it is fixedly connected with the first support platform, the second support platform, and the third support platform in sequence. After each connection, the corresponding cleaning nozzle, inspection nozzle, or anti-rust nozzle is activated and driven by a drive mechanism to move horizontally inside the bent copper tube, thereby completing the cleaning and drying of the inner wall of the bent copper tube, the rust removal effect inspection, and the anti-rust paint spraying in sequence. This application integrates the three processes of cleaning, inspection, and spraying into the same device in terms of height. By switching and connecting the workstation support platform with the first support platform, the second support platform, and the third support platform, the device floor space is reduced. At the same time, the copper tube can complete the automated processing of multiple processes in a single clamping state, avoiding the positioning error and time loss caused by repeated clamping of the copper tube between different devices, and improving the processing efficiency. 2. This application utilizes a winding roller to store and release long-distance textured tubes, meeting the requirement for long-stroke movement of the cleaning nozzle within a limited space; the lead wire structure ensures the stability of the textured tube during its transport from the second mounting frame to the first support platform, preventing the textured tube from tangling or getting stuck; the anti-bending structure functions after the textured tube extends into the copper tube, preventing the textured tube from stacking or bending due to gravity or resistance inside the bent copper tube, ensuring that the cleaning nozzle can smoothly reach the depths of the bent copper tube, achieving full-length inner wall cleaning, while avoiding cleaning blind spots or nozzle jamming caused by bending; 3. The device is equipped with two sets of equipment, which not only allows for the simultaneous processing of two sets of bent copper tubes, but also enables the processing of "U" shaped copper tubes. This improves the overall working efficiency of the device and also makes the device multifunctional. Attached Figure Description

[0027] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0028] This application discloses a copper pipe cleaning and rust prevention detection device and its rust prevention detection process, referring to... Figure 1 , Figure 2 and Figure 3A copper pipe cleaning and rust prevention testing device includes an operating table 1. A first mounting frame 11 and a second mounting frame 12 are fixedly mounted on the operating table 1. A first support platform 121, a second support platform 122, and a third support platform 123 are fixedly mounted on the side of the second mounting frame 12 closest to the first mounting frame 11. The first support platform 121 is spaced apart directly below the second support platform 122, and the second support platform 122 is spaced apart directly below the third support platform 123. A cleaning nozzle 124 for cleaning and drying the inner wall of the copper pipe is horizontally movably mounted on the first support platform 121. A testing head 125 for testing the rust removal effect on the inner wall of the copper pipe is horizontally movably mounted on the second support platform 122. A rust-preventing paint spraying device is horizontally movably mounted on the third support platform 123. The rust-preventing nozzle 126 has a workstation support platform 127 that is raised and lowered on the side of the first mounting frame 11 away from the second mounting frame 12. A connecting structure 2 is provided between the workstation support platform 127 and the first support platform 121 to fix the workstation support platform 127 to the first support platform 121. The operating table 1 is provided with a lifting component 3 for horizontally moving and vertically raising and lowering the workstation support platform 127, so that the workstation support platform 127 is fixedly connected to the first support platform 121, the second support platform 122 and the third support platform 123 respectively. The second support platform 122 and the third support platform 123 are set with the first support platform 121. The second mounting frame 12 is provided with a drive mechanism 4 for driving the cleaning nozzle 124, the detection head 125 and the rust-preventing nozzle 126 to move inside the bent copper tube.

[0029] The lifting assembly 3 vertically lifts and horizontally moves the workstation support platform 127, allowing it to sequentially and permanently connect with the first support platform 121, the second support platform 122, and the third support platform 123. After each connection, the corresponding cleaning nozzle 124, inspection head 125, or anti-rust nozzle 126 is activated, and driven by the drive mechanism 4, it moves horizontally inside the copper tube, sequentially completing the cleaning and drying of the inner wall of the copper tube, the rust removal effect inspection, and the anti-rust paint spraying. This embodiment integrates the three processes of cleaning, inspection, and spraying into the same device in terms of height. By switching and connecting the workstation support platform 127 with the first support platform 121, the second support platform 122, and the third support platform 123, the device footprint is reduced, and the copper tube can be automatically processed in a single clamping state, avoiding positioning errors and time losses caused by repeated clamping of the copper tube between different devices, thus improving processing efficiency.

[0030] Reference Figure 3The connecting structure 2 includes a first socket post 21, a second socket post 22, and an electromagnet. The first socket post 21 is fixedly installed at the end of the workstation support platform 127, and the second socket post 22 is fixedly installed at the end of the first support platform 121. The end of the workstation support platform 127 is provided with a first socket slot corresponding to the second socket post 22, and the end of the first support platform 121 is provided with a second socket slot corresponding to the first socket post 21. The first socket post 21 is inserted into the second socket slot, and the second socket post 22 is inserted into the first socket slot. Multiple sets of electromagnets are provided, and the multiple sets of electromagnets are respectively embedded in the ends of the first socket post 21 and the second socket post 22, as well as on the bottom wall of the first socket slot and the second socket slot.

[0031] When the workstation support platform 127 is moved by the lifting assembly 3 to a predetermined position that fits against the first support platform 121, the second support platform 122, or the third support platform 123, the first socket post 21 at the end of the workstation support platform 127 is inserted into the second socket at the end of the corresponding first support platform 121, the second support platform 122, or the third support platform 123, and at the same time, the second socket post 22 at the end of the corresponding first support platform 121, the second support platform 122, or the third support platform 123 is inserted into the first socket at the end of the workstation support platform 127, forming a bidirectional socket fit; subsequently, multiple sets of electromagnets embedded in the ends of the first socket post 21 and the second socket post 22 and the bottom walls of the first socket and the second socket are simultaneously energized, generating magnetic attraction to firmly attract the workstation support platform 127 to the corresponding first support platform 121, the second support platform 122, or the third support platform 123. This embodiment utilizes the energization and attraction of multiple sets of electromagnets to achieve rapid locking after docking and rapid separation after power failure, meeting the requirement of rapid decoupling during process switching and improving the reliability of docking and switching efficiency.

[0032] Reference Figure 1 The lifting assembly 3 includes a lifting platform 31, a first drive motor 32, a first lead screw 33, a column 34, a cylinder 35, a first limiting block 36, and a second limiting block 37. The first drive motor 32 is fixedly mounted on the first mounting bracket 11. The first lead screw 33 is vertically fixedly mounted on the output shaft of the first drive motor 32. The lifting platform 31 is lifted and mounted on the operating table 1 and is threadedly connected to the first lead screw 33. Multiple sets of columns 34 are provided, and all sets of columns 34 are vertically fixedly mounted on the operating table 1 and are slidably connected to the lifting platform 31. The cylinder 35 is fixedly mounted on the lifting platform 31. The first limiting block 36 is fixedly mounted on the telescopic end of the cylinder 35 and is used to limit the bending part of the copper tube. The second limiting block 37 is fixedly mounted on the lifting platform 31 and is used to limit the straight part of the copper tube. The cylinder 35 drives the workstation support platform 127 to move towards the first support platform 121 by pushing the first limiting block 36.

[0033] The first drive motor 32 drives the first lead screw 33 to rotate, causing the lifting platform 31 to rise and fall vertically along multiple sets of columns 34, thereby adjusting the height of the workstation support platform 127 in the vertical direction; then the cylinder 35 pushes the first limiting block 36 fixed to its telescopic end, and the first limiting block 36 causes the workstation support platform 127 to move horizontally in the direction of the first support platform 121, the second support platform 122, or the third support platform 123; in this embodiment, through the cooperation of the first drive motor 32 and the first lead screw 33, the lifting and lowering of the workstation support platform 127 between different height workstations is realized, reducing the floor space required by the device.

[0034] Reference Figure 4 and Figure 5 The drive mechanism 4 includes a first drive assembly 41, a second drive assembly, and a third drive assembly. The first drive assembly 41 drives the cleaning nozzle 124 to move, the second drive assembly drives the detection head 125 to move, and the third drive assembly drives the rust-preventing nozzle 126 to move. The first drive assembly 41 includes a second drive motor 411, a winding roller 412, a textured tube 413, a lead wire structure 414, and an anti-bending structure 415. The second drive motor 411 is fixedly mounted on the second mounting bracket 12 away from the first mounting bracket 11. On one side, the winding roller 412 is fixedly mounted on the output shaft of the second drive motor 411, one end of the textured tube 413 is fixedly mounted on the winding roller 412, the cleaning nozzle 124 is fixedly mounted on the end of the textured tube 413 away from the winding roller 412, the lead wire structure 414 is mounted on the side of the second mounting frame 12 away from the first mounting frame 11, and is used to stably output the textured tube 413 to the first support platform 121, and the anti-bending structure 415 is mounted on the second mounting frame 12, and is used to prevent the textured tube 413 from stacking inside the bent copper tube.

[0035] In this embodiment, the long-distance textured tube 413 is stored and released by the winding roller 412, which meets the long-stroke movement requirement of the cleaning nozzle 124 within a limited space. The lead wire structure 414 ensures the stability of the textured tube 413 during the process of being transported from the second mounting frame 12 to the first support platform 121, and prevents the textured tube 413 from getting tangled or stuck. The anti-bending structure 415 plays a role after the textured tube 413 extends into the bent copper tube, preventing the textured tube 413 from stacking or bending inside the bent copper tube due to gravity or resistance, ensuring that the cleaning nozzle 124 can smoothly reach the depth of the bent copper tube, realize full-length inner wall cleaning, and avoid cleaning blind spots or nozzle jamming caused by bending.

[0036] Reference Figure 4 and Figure 5The lead wire structure 414 includes a third drive motor 4141, a drive gear 4142, a driven gear 4143, a drive clamping roller 4144, a driven clamping roller 4145, and a lead wire tube 4146. The third drive motor 4141 is fixedly mounted on the side of the second mounting bracket 12 away from the first mounting bracket 11. The drive gear 4142 is fixedly mounted on the output shaft of the third drive motor 4141. The drive clamping roller 4144 is fixedly mounted on the side of the drive gear 4142 away from the third drive motor 4141. The driven gear 4143 is rotatably mounted on the drive gear 4146. Directly below 142, with the driving gear 4142 and driven gear 4143 meshing with each other, the driven clamping roller 4145 is fixedly disposed on the side of the driven gear 4143 away from the third drive motor 4141, and located directly below the driving clamping roller 4144. The driving clamping roller 4144 and the driven clamping roller 4145 are used to clamp and transport the output mesh tube 413. The lead tube 4146 is fixedly disposed on the side of the second mounting frame 12 close to the first mounting frame 11, and is used to guide the mesh tube 413 between the first mounting frame 11 and the second mounting frame 12.

[0037] The third drive motor 4141 drives the drive gear 4142 to rotate, and the drive gear 4142 drives the driven gear 4143 meshing with it to rotate in the opposite direction. The drive clamping roller 4144 rotates synchronously with the drive gear 4142, and the driven clamping roller 4145 rotates synchronously with the driven gear 4143. The drive clamping roller 4144 and the driven clamping roller 4145 clamp the passing mesh tube 413 and apply a conveying force, drawing the mesh tube 413 out from the winding roller 412 and pushing it forward. After being output by the drive clamping roller 4144 and the driven clamping roller 4145, the mesh tube 413 enters the... The guide tube 4146 is fixedly installed and guides the coiled tube 413 between the first mounting frame 11 and the second mounting frame 12. This avoids the bending of the coiled tube 413 caused by uneven thrust when unwinding from the winding roller 412. The guide tube 4146 provides a guiding path for the coiled tube 413, ensuring that the coiled tube 413 remains straight and oriented accurately as it crosses from the second mounting frame 12 to the first support platform 121. This provides accurate initial alignment for subsequent entry into the copper tube and reduces the swaying and friction of the coiled tube 413 during the conveying process, thus improving the stability of the conveying.

[0038] Reference Figure 4The anti-bending assembly includes a fourth drive motor 4151, a second lead screw 4152, a moving plate 4153, a limiting rod 4154, a snake-bone tube 4155, and an energized coil 4156. The fourth drive motor 4151 is fixedly mounted on the side of the second mounting bracket 12 away from the first mounting bracket 11. The second lead screw 4152 is rotatably mounted between the first mounting bracket 11 and the second mounting bracket 12 and is fixedly connected to the output shaft of the fourth drive motor 4151. The limiting rod 4154 is parallel to the second lead screw 4152 and fixedly mounted between the first mounting bracket 11 and the second mounting bracket 12. The moving plate 4153 is slidably mounted on the limiting rod 4154 and is threadedly connected to the second lead screw 4152. The snake-bone tube... One end of 4155 is fixedly mounted on the side of the movable plate 4153 away from the second mounting bracket 12. When the snake bone tube 4155 is located between the first mounting bracket 11 and the second mounting bracket 12, the snake bone tube 4155 is sleeved on the first support platform 121. When the snake bone tube 4155 is located on the side of the first mounting bracket 11 away from the second mounting bracket 12, the snake bone tube 4155 is sleeved on the workstation support platform 127. The first mounting bracket 11 has a through hole for the snake bone tube 4155 to pass through. The snake bone tube 4155 includes multiple snake bone segments. Multiple sets of energized coils 4156 are provided. The multiple sets of energized coils 4156 are respectively fixedly mounted on the inner wall of the multiple sets of snake bone segments. The inside of the mesh tube 413 is filled with magnetorheological fluid.

[0039] The fourth drive motor 4151 drives the second lead screw 4152 to rotate, causing the moving plate 4153 to move horizontally along the limit rod 4154. The moving plate 4153 drives the snake tube 4155 to extend or retract synchronously. When the snake tube 4155 extends, it passes through the through hole on the first mounting bracket 11 in sequence. When it is between the first mounting bracket 11 and the second mounting bracket 12, it is sleeved on the first support platform 121. After passing through the first mounting bracket 11, it is sleeved on the workstation support platform 127 and corresponds to the inside of the copper tube. During the process of the snake-bone tube 4155 extending into the copper tube, multiple sets of energized coils 4156 set on the inner wall of each snake-bone section are energized, generating a magnetic field that acts on the magnetorheological fluid inside the mesh tube 413, causing the magnetorheological fluid to change from a liquid state to a near-solid state, thereby increasing the bending stiffness of the mesh tube 413. This enables real-time controllable adjustment of the rigidity of the mesh tube 413. When it needs to be extended, the energizer increases rigidity to prevent stacking, and when it needs to be retracted, the energizer is de-energized to restore flexibility for easy winding, thus ensuring the uniformity and thoroughness of cleaning the inner wall of the entire section.

[0040] Reference Figure 3 The inner wall of the snake bone joint is provided with a support block 5, and the support block 5 is provided with a ball bearing. The first support platform 121, the second support platform 122, the third support platform 123 and the work station support platform 127 are all provided with guide grooves 51, and the ball bearing is rolled in the guide grooves 51.

[0041] When the snake-bone tube 4155 moves telescopically along the first support platform 121, the second support platform 122, the third support platform 123, or the workstation support platform 127 under the drive of the moving plate 4153, the ball bearings provided on the support block 5 on the inner wall of the snake-bone section are embedded in the guide grooves 51 opened on the corresponding support platforms and roll along the guide grooves 51. Through the cooperation between the ball bearings and the guide grooves 51, the sliding friction between the snake-bone tube 4155 and the support platform is converted into rolling friction, which significantly reduces the frictional resistance during the telescopic process of the snake-bone tube 4155, reduces the load on the drive mechanism 4, and improves the smoothness and response speed of the snake-bone tube 4155 movement. At the same time, the guide grooves 51 guide and limit the ball bearings, ensuring that the snake-bone tube 4155 always remains coaxial with the workstation support platform 127, the first support platform 121, the second support platform 122, or the third support platform 123 during the movement, preventing the snake-bone tube 4155 from radially deviating or twisting.

[0042] Reference Figure 1 The first support platform 121, the second support platform 122, the third support platform 123, the workstation support platform 127, the cleaning nozzle 124, the inspection head 125, the rust-preventing nozzle 126, and the drive structure are all arranged in two sets along the length of the operating platform 1, for processing "U"-shaped copper tubes. The two sets not only allow for simultaneous processing of two sets of bent copper tubes but also enable the processing of "U"-shaped copper tubes, improving the overall working efficiency of the device and realizing its multi-functionality.

[0043] The implementation principle of the copper pipe cleaning and rust prevention detection device and its rust prevention detection process in this application embodiment is as follows: When it is necessary to fix the copper pipe, the first limiting block 36 limits the bent part of the copper pipe, and the second limiting block 37 limits the straight part of the copper pipe. When the workstation support platform 127 needs to be connected with the first support platform 121, the second support platform 122 or the third support platform 123, the first drive motor 32 drives the first lead screw 33 to rotate, which drives the lifting platform 31 to rise and fall along multiple sets of columns 34. The cylinder 35 pushes the first limiting block 36 to move the workstation support platform 127 horizontally, so that the first socket 21 is inserted into the second socket, the second socket 22 is inserted into the first socket, and multiple sets of electromagnets are energized to attract and fix the pipe.

[0044] When cleaning is required, the second drive motor 411 drives the tube roller 412 to rotate, and the third drive motor 4141 drives the driving gear 4142 and the driven gear 4143 to rotate in opposite directions. The driving clamping roller 4144 and the driven clamping roller 4145 clamp the conveying mesh tube 413 and guide it through the lead tube 4146 to the space between the first mounting frame 11 and the second mounting frame 12. The cleaning nozzle 124 enters the copper tube. At the same time, the fourth drive motor 4151 drives the second lead screw 4152 to rotate, which in turn drives the moving plate 4153. The movement along the limiting rod 4154 causes the snake bone tube 4155 to extend synchronously and be fitted onto the workstation support platform 127. Multiple sets of energized coils 4156 are energized to solidify the magnetorheological fluid inside the textured tube 413, and the balls on the inner wall support block 5 of the snake bone joint roll along the guide groove 51. When testing is required, the second drive assembly drives the detection head 125 to extend horizontally from the second support platform 122 into the copper tube. When spraying is required, the third drive assembly drives the anti-rust spray head 126 to extend horizontally from the third support platform 123 into the copper tube.

[0045] This embodiment also includes a copper pipe cleaning and rust prevention inspection process, comprising the following steps: S1: Place the copper tube on the workstation support platform 127 and fix it by limiting it with the first limiting block 36 and the second limiting block 37; start the lifting assembly 3 to raise the workstation support platform 127 to the same height as the first support platform 121, and then push the workstation support platform 127 and the first support platform 121 closer by the cylinder 35; complete the socket engagement by the connecting structure 2, and achieve the fixed connection between the workstation support platform 127 and the first support platform 121 by energizing multiple sets of electromagnets; then reset the lifting assembly 3. S2: The first drive assembly 41 drives the winding roller 412 to release the textured tube 413. Guided by the active clamping roller 4144, the driven clamping roller 4145 and the lead tube 4146 in the lead wire structure 414, the cleaning nozzle 124 is horizontally sent into the copper tube. At the same time, the fourth drive motor 4151 in the anti-bending structure 415 drives the second lead screw 4152 to move the moving plate 4153. The snake-bone tube 4155 enters the copper tube synchronously with the cleaning nozzle 124. The energized coil 4156 on the inner wall of the snake-bone joint is energized to improve the solidity of the magnetorheological fluid inside the textured tube 413 to prevent stacking. The cleaning nozzle 124 moves and sprays cleaning fluid to complete the inner wall cleaning. Then it switches to high-pressure gas for drying. After completion, the cleaning nozzle 124 retracts. S3: The electromagnet is de-energized and disconnected. The lifting assembly 3 adjusts the workstation support platform 127 to the same height as the second support platform 122. The cylinder 35 pushes and the connecting structure 2 to achieve a fixed docking with the second support platform 122. Then the lifting assembly 3 is reset. The second drive assembly is started to send the detection head 125 horizontally from the second support platform 122 into the copper tube. It moves along the inner wall to complete the rust removal effect detection. After the detection, the detection head 125 is retracted. S4: Disconnect again. The lifting component 3 adjusts the workstation support platform 127 to the same height as the third support platform 123. The cylinder 35 pushes and the connecting structure 2 to achieve a fixed docking with the third support platform 123. Start the third drive component to send the anti-rust spray head 126 horizontally from the third support platform 123 into the copper pipe. Move along the inner wall and spray the anti-rust paint evenly. After completion, the anti-rust spray head 126 retracts. S5: When the electromagnet is de-energized, the connection is released, and the lifting assembly 3 drives the workstation support platform 127 back to the initial position to remove the processed copper pipe.
