Description

Technical Field

[0001] This invention relates to the field of corrugated pipe installation technology, specifically to a pipe head cleaning device for MPVE double-wall corrugated pipe installation. Background Technology

[0002] MPVE double-wall corrugated pipe is a new type of pipe material, made by blending polyethylene resin, polyvinyl chloride resin, compatibilizers, and other polymers. This pipe combines the toughness of polyethylene with the rigidity of polyvinyl chloride, while also possessing advantages such as oxidation resistance and flame retardancy. The design of MPVE double-wall corrugated pipe compensates for the shortcomings of polyethylene corrugated pipe (good toughness but insufficient rigidity and rapid oxidation) and overcomes the deficiency of polyvinyl chloride (good rigidity but poor toughness). MPVE double-wall corrugated pipe also features convenient installation and transportation, good sealing performance, and excellent hydraulic characteristics. Its lightweight and flexible characteristics make transportation and installation easier, reducing construction difficulty and costs. The flexible joint design of the rubber ring socket connection ensures the sealing of the pipeline system, effectively preventing leakage.

[0003] In current pipe connection and cleaning technologies, especially for pipes with special structures such as corrugated pipes, the cleaning work before connection is particularly important. Existing cleaning methods and technologies have significant shortcomings when dealing with the cleaning task before two corrugated pipe sections are joined. Traditional cleaning methods often rely on manual hand-held cleaning tools. Manual cleaning is often difficult to precisely control the cleaning force and scope, resulting in inconsistent cleaning results. For corrugated pipes, which have complex geometric shapes and multi-layered structures, manual cleaning is difficult to reach every tiny gap and corner, leaving cleaning blind spots and increasing the risk of leakage after pipe connection. Moreover, when two corrugated pipes are joined, since the pipe head of one of the corrugated pipes is in the installation position, it needs to be manually lifted by the staff before the part in contact with the soil can be cleaned. Once the corrugated pipe is put down, it will be contaminated with dust, affecting the installation and connection of the corrugated pipe head.

[0004] Therefore, we propose a pipe head cleaning device for MPVE double-wall corrugated pipe installation. Summary of the Invention

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 - Figure 5This invention provides a technical solution: a pipe head cleaning device for MPVE double-wall corrugated pipe installation, including a moving platform 1, a hanging plate 2, and a main corrugated pipe 111 and an auxiliary corrugated pipe 112 that are connected to each other. The main corrugated pipe 111 and the auxiliary corrugated pipe 112 are both placed below the hanging plate 2 and are arranged opposite each other. The upper inner top of the moving platform 1 is provided with a lifting component that drives the hanging plate 2 to move up and down. The upper top of the hanging plate 2 is provided with a driving component that serves as a power source. The lower bottom of the hanging plate 2 is provided with a cleaning component that removes dust from the main corrugated pipe 111 and the auxiliary corrugated pipe 112. The lower bottom of the hanging plate 2 is provided with a conveying component that drives the cleaning component to move. The lower bottom of the hanging plate 2 is located on one side of the cleaning component and is provided with a clamping component that limits the movement of the main corrugated pipe 111. The upper top of the hanging plate 2 is provided with a clutch component that controls the operation of the cleaning component, the clamping component, and the conveying component respectively.

[0021] By adopting the above technical solution, the cleaning component integrated below the hanging plate 2 can automatically remove dust from the pipe heads of the main corrugated pipe 111 and the auxiliary corrugated pipe 112. Under the powerful drive of the drive component and combined with the precise movement control of the conveying component, the cleaning component can thoroughly remove dust and impurities from the inner and outer walls of the pipe heads, effectively avoiding installation problems caused by incomplete manual cleaning, and improving the sealing and stability of the pipe connection. The clamping component can firmly limit the main corrugated pipe 111 before cleaning, ensuring that it remains stable in position throughout the cleaning process without shifting or shaking. This not only improves the efficiency of the cleaning operation but also ensures the consistency of the cleaning effect and avoids cleaning blind spots caused by changes in the position of the pipe head. The lifting component allows the hanging plate 2 and all working components below it to move up and down as needed, thus easily adapting to pipe installation environments of different heights and positions. In addition, the introduction of the clutch component allows the operator to independently control the working status of the cleaning component, clamping component, and conveying component as needed, realizing a flexible and versatile operating mode and further improving the adaptability and practicality of the device.

[0022] Please see Figure 1 - Figure 3The lifting assembly includes a first motor 11 fixedly connected to the top of the inner side of the moving platform 1. A first drive rod 12 is fixedly connected to the output end of the first motor 11. An auxiliary drive rod 15 is provided on one side of the first drive rod 12 at the top of the inner side of the moving platform 1. A first synchronous wheel 16 is fixedly sleeved on the outer wall of both the first drive rod 12 and the auxiliary drive rod 15. A first synchronous belt 17 is sleeved on the outer wall of the first synchronous wheel 16. A first bearing seat 13 is fixedly connected to the end of both the first drive rod 12 and the auxiliary drive rod 15. The upper top of the first bearing seat 13 is fixedly connected to the top of the inner side of the moving platform 1. Two pairs of cable rollers 14 are fixedly sleeved on the outer surface of both the first drive rod 12 and the auxiliary drive rod 15. A sling 141 is wound around the outer wall of the cable roller 14. A hook 142 is fixedly connected to the end of the sling 141. Hooks 143, which are fixedly sleeved with hooks 142, are symmetrically fixedly connected to the top of the lifting plate 2.

[0023] Using the above technical solution, the first motor 11 serves as the power source, directly driving the first drive rod 12 to rotate. Then, through the transmission action of the first synchronous pulley 16 and the first synchronous belt 17, the auxiliary drive rod 15 rotates synchronously. This dual-rod synchronous drive design ensures a smooth and uniform lifting process, effectively avoiding vibration or offset problems caused by a single drive point, and improving the stability of the lifting operation. The ingenious design of the cable rollers 14 allows the slings 141 to extend and retract freely as needed, thereby achieving precise control of the lifting height of the suspended platform 2. The two pairs of cable rollers 14... The design not only enhances the load-bearing capacity and stability of the cable system, but also ensures the balance of the suspended platform 2 during the lifting process, preventing tilting caused by uneven force on one side. The sling 141 is fixedly connected to the hook 143 on the suspended platform 2 through the hook 142. This connection method is simple and strong, and can withstand large tensile and impact forces, ensuring the safety of the suspended platform 2 during the lifting process. The stable installation of the first bearing seat 13 provides solid support for the first drive rod 12 and the auxiliary drive rod 15, further enhancing the reliability and durability of the entire lifting assembly.

[0024] Please see Figure 3 and Figure 5 The drive assembly includes a second motor 21 fixedly connected to the top of the hanging plate 2. The output end of the second motor 21 is fixedly connected to a second drive rod 22. The end of the second drive rod 22 is fixedly connected to a second bearing seat 23 for support, and the bottom end of the second bearing seat 23 is fixedly connected to the top of the hanging plate 2.

[0025] Using the above technical solution, the second motor 21 serves as the core power source, directly driving the second drive rod 22 to rotate, thus achieving efficient power transmission. The direct drive method reduces energy loss during the energy conversion process, ensuring the stability and continuity of power output, and providing strong support for subsequent cleaning, clamping, and conveying operations. The second drive rod 22 is securely mounted on the hanging plate 2 via the second bearing seat 23. This design not only enhances the overall stability of the drive assembly but also ensures the coaxiality and accuracy of the second drive rod 22 during high-speed rotation, avoiding the problem of power transmission being affected by vibration or offset.

[0026] Please see Figure 5 , Figure 9 and Figure 11 The clamping assembly includes a connecting rod 4 rotatably connected to the top of the hanging plate 2. Two third bearing seats 41, serving as supports, are fixedly sleeved on the outer wall of the connecting rod 4. The lower end of the third bearing seats 41 is fixedly connected to the upper top of the hanging plate 2. A sixth gear 72 is rotatably sleeved at the end of the connecting rod 4. A fifth gear 71, meshing with the sixth gear 72, is fixedly sleeved on the outer wall of the second drive rod 22. Worms 42 are symmetrically fixedly sleeved on the outer wall of the connecting rod 4. A turbine 43, meshing with the worm 42, is rotatably connected to the upper top of the hanging plate 2. A threaded rod 44 is fixedly connected to the lower bottom of the turbine 43, and the threaded rod 44 is rotatably connected to the hanging plate 2. A sleeve 45 is threaded onto the outer wall. One end of a second connecting rod 53 is symmetrically rotatably connected to the outer wall of the sleeve 45. A fixed bracket 5 is symmetrically fixedly connected to the bottom end of the hanging plate 2. A side bracket 51 is fixedly connected to the outer wall of the fixed bracket 5 near the threaded rod 44. A V-shaped connecting rod 55 is symmetrically rotatably connected to the inner wall of the side bracket 51. The other end of the second connecting rod 53 is rotatably connected to the center of the outer wall of the V-shaped connecting rod 55. A clamping frame 54 for limiting the main bellows 111 is rotatably connected to the end of the V-shaped connecting rod 55. A first connecting rod 52 is rotatably connected to the bottom end of the fixed bracket 5, and the end of the first connecting rod 52 is rotatably connected to the inner wall of the clamping frame 54.

[0027] By employing the above technical solution, the efficient transmission of power from the drive assembly to the clamping assembly is achieved through the meshing transmission of the second drive rod 22 with the fifth gear 71 and the sixth gear 72. The meshing transmission of the worm gear 42 with the turbine 43 drives the threaded rod 44 to rotate, thereby causing the sleeve 45 to move along the thread direction. This ensures the synchronicity and accuracy of the clamping frame 54 during the opening and closing process, accurately clamping the main bellows 111 and preventing it from moving or shaking during cleaning. Since the threaded rod 44 and the sleeve 45 are connected by threads, a certain self-locking force can be generated when the sleeve 45 moves, ensuring that the clamping frame 54 remains in place during the clamping process. Maintaining a stable clamping force, the clamping assembly can flexibly adjust the position and angle of the clamping frame 54 through the linkage of the first link 52, the second link 53, and the V-shaped link 55. In addition, the design of the V-shaped link 55 allows the clamping frame 54 to adaptively adjust the clamping angle and force when contacting the main bellows 111, ensuring that bellows of different diameters and shapes can be firmly clamped. The third bearing seat 41 provides a stable support for the connecting rod 4, ensuring the stability and reliability of the transmission system. At the same time, the worm gear 42 and the turbine gear 43 have a large transmission ratio and self-locking properties, which can maintain the clamping state in the event of power failure or malfunction, preventing accidental loosening.

[0028] Please see Figure 4 - Figure 7 The conveying assembly includes sprockets 82 symmetrically rotatably connected to the bottom end of the hanging plate 2. One end of the sprocket 82 is fixedly connected to an extension rod 81. The end of the extension rod 81 is fixedly sleeved with a seventh gear 8 for transmission. The outer wall of the second drive rod 22 is rotatably sleeved with an eighth gear 84 that meshes with the seventh gear 8 for transmission. The outer wall of the sprocket 82 is meshed with a chain 83.

[0029] By adopting the above technical solution, the conveying component achieves direct and efficient power transmission from the drive component to the conveying component through the ingenious connection between the second drive rod 22, the eighth gear 84, the seventh gear 8, and the extension rod 81. This reduces energy loss during transmission and ensures that the conveying component can obtain sufficient driving force to cope with various complex conveying tasks. The meshing design of the sprocket 82 and the chain 83 ensures the synchronization and stability of the conveying process. The chain 83 transmission has the advantages of high load-bearing capacity, smooth transmission, and wear resistance. Even when operating at high speed or under heavy load, it can maintain a stable conveying effect and effectively avoid damage caused by asynchronous or fluctuating conveying.

[0030] Please see Figure 8 and Figure 10The cleaning assembly includes a main cleaning structure for cleaning the outer wall of the main bellows 111 and an auxiliary cleaning structure for cleaning the inner wall of the auxiliary bellows 112, as well as a transmission structure for driving the cleaning assembly. The transmission structure includes a rotating rod 6 rotatably connected to the bottom end of the hanging plate 2. Both ends of the rotating rod 6 are fixedly sleeved with fourth bearing seats 62, and the upper top of the fourth bearing seats 62 is fixedly connected to the bottom end of the hanging plate 2. A second synchronous pulley 26 is fixedly sleeved on the outer wall of the rotating rod 6. The outer wall of the second drive rod 22 is also rotatably sleeved with a second synchronous pulley 26. A second synchronous belt 27 for transmission is sleeved on the outer wall of the second synchronous pulley 26. A first outer support frame 61 is slidably connected to the wall. A first gear 611 and a second gear 612 are rotatably connected to the inner bottom end and inner side wall of the first outer support frame 61, respectively. The second gear 612 is slidably sleeved with the rotating rod 6. A support rod 64 is fixedly connected to the lower bottom end of the first gear 61. The end of the support rod 64 passes through the lower bottom end of the first outer support frame 61 and is fixedly connected to a third gear 65. A second outer support frame 63 is rotatably sleeved on the outer wall of the support rod 64. A fourth gear 66 that meshes with the third gear 65 is symmetrically rotatably connected to the inner side wall of the second outer support frame 63. A circular chuck 9 is symmetrically fixedly connected to the outer wall of the second outer support frame 63.

[0031] By adopting the above technical solution, the cleaning component cleverly combines a main cleaning structure and an auxiliary cleaning structure to clean the outer wall of the main bellows 111 and the inner wall of the auxiliary bellows 112, respectively. The dual cleaning mechanism ensures comprehensive coverage of the inner and outer surfaces of the bellows, effectively removing dirt and impurities and improving the cleaning effect. The transmission structure achieves efficient power transmission from the second drive rod 22 to the rotating rod 6 through the meshing of the second synchronous pulley 26 and the second synchronous belt 27. This synchronous transmission method ensures that the rotation of the rotating rod 6 is highly consistent with that of the second drive rod 22, thereby ensuring the stable operation and synchronous operation of the cleaning component. The first outer support 61, the second outer support 63 and the gear transmission system (first gear 611, second gear 612, third gear 65 and fourth gear 66) in the transmission structure constitute a multi-stage transmission mechanism, which not only realizes the step-by-step transmission of power, but also achieves precise control of the movement trajectory and speed of the cleaning component through the precise meshing of the gears, thereby improving the accuracy and efficiency of the cleaning operation.

[0032] Please see Figure 13 and Figure 14The main cleaning structure includes a support frame 91 symmetrically arranged at the bottom of the hanging plate 2. A toothed ring 92 is fixedly sleeved at the bottom of the support frame 91. Two fourth gears 66 pass through a circular chuck 9 on opposite sides and are fixedly connected to an internal gear 93. The internal gear 93 is located at the center of the toothed ring 92. A first external gear 94 meshes with the lower part of the internal gear 93. The first external gear 94 meshes with the toothed ring 92. An outer slide rail 942 is fixedly connected to the outer wall of the first external gear 94 on the side away from the circular chuck 9. An outer plate 941 is fixedly connected to the outer wall of the first external gear 94 at the end of the outer slide rail 942. A first torque rod 943 is threadedly sleeved at the top of the outer plate 941. A cleaning sponge 944 for cleaning is slidably connected inside the outer slide rail 942, and the end of the first torque rod 943 is rotatably sleeved with the cleaning sponge 944.

[0033] By adopting the above technical solution, the main cleaning structure ensures the synchronous movement of each component during the cleaning process through the meshing of the first external gear 94 and the internal gear 93, as well as the double meshing transmission between the first external gear 94 and the gear ring 92. This effectively avoids the problem of uneven cleaning caused by asynchronous transmission, and improves cleaning efficiency and quality. Under the guidance of the gear ring 92, the first external gear 94 can rotate along the gear ring 92 and thus adaptively adjust its position, allowing the cleaning sponge 944 to adhere tightly to the outer wall of the corrugated pipe for cleaning. At the same time, by adjusting the tightness of the first torque rod 943, the pressure of the cleaning sponge 944 on the surface of the corrugated pipe can be easily adjusted, thereby ensuring the cleaning effect while avoiding damage to the surface of the corrugated pipe. As the cleaning medium that directly contacts the outer wall of the corrugated pipe, the cleaning sponge 944 can be replaced according to different cleaning needs.

[0034] Please see Figure 12 - Figure 15 The auxiliary cleaning structure includes a second external gear 10 meshing with another internal gear 93 on one side. A fixed plate 101 is fixedly connected to the outer wall of the second external gear 10 away from the circular chuck 9. A second torque rod 102 is threaded onto the inner wall of the fixed plate 101. An auxiliary plate 103 is fixedly connected to the outer wall of the second external gear 10 on one side of the fixed plate 101. A cleaning cotton swab 104 is slidably connected to the auxiliary plate 103 near the fixed plate 101, and the end of the second torque rod 102 is rotatably sleeved with the end of the cleaning cotton swab 104.

[0035] Using the above technical solution, the auxiliary cleaning structure achieves precise positioning of the inner wall of the auxiliary corrugated pipe 112 through the meshing transmission of the second external gear 10 and the internal gear 93, ensuring that the cleaning cotton swab 104 can penetrate deep into the corrugated pipe to thoroughly clean hard-to-reach corners and gaps, effectively removing dirt and impurities from the inner wall. By adjusting the tightness of the second torque rod 102, the pressure of the cleaning cotton swab 104 on the inner wall of the auxiliary corrugated pipe 112 can be easily adjusted. The sliding connection design between the auxiliary plate 103 and the cleaning cotton swab 104 allows the cleaning cotton swab to flexibly adjust its position according to the shape change of the inner wall of the corrugated pipe, which not only improves the flexibility of cleaning but also ensures the close contact between the cotton swab and the inner wall during the cleaning process, further improving the cleaning effect. During use, the cleaning cotton swab 104 can be inserted into the interior of the auxiliary corrugated pipe 112 by moving the moving platform 1, and then the moving platform 1 can be moved to clamp the main corrugated pipe 111 through the clamping assembly.

[0036] Please see Figure 4 - Figure 10 The outer walls of the second drive rod 22, the connecting rod 4, and the rotating rod 6 are all provided with spline grooves 221. The bottom end of the hanging plate 2 is symmetrically and fixedly connected with the main slide rail 24.

The top end of the support frame 91 is slidably connected to the inside of the main slide rail 24. The top end of the first outer support frame 61 is slidably connected to the inside of the auxiliary slide rail 25. The top end of the two support frames 91 near the circular chuck 9 is provided with a connecting frame 95 connected to the chain 83.

[0037] By adopting the above technical solution, the spline groove 221 designed on the outer wall of the second drive rod 22, connecting rod 4, and rotating rod 6 provides a more stable and reliable path for power transmission. The introduction of the main slide rail 24 and auxiliary slide rail 25 provides precise guidance for the support frame 91 and the first outer support frame 61. Through sliding connection inside the slide rail, these components can move smoothly along a predetermined trajectory, reducing friction and wear caused by positional deviation. This not only reduces maintenance costs but also improves the overall performance and reliability of the equipment. The robust structure of the main slide rail 24 and auxiliary slide rail 25 provides strong support for the entire cleaning assembly, bearing the weight and force from the support frame 91 and the first outer support frame 61, and ensuring the stability and precision of the entire assembly during operation through stable guidance.

[0038] Please see Figure 5 - Figure 16The clutch assembly includes a first support 3 fixedly connected to the top of the hanging plate 2. A first hydraulic push rod 31 is fixedly connected to the inner wall of the first support 3. A first friction cam 35 is fixedly connected to the side of the second synchronous pulley 26 near the eighth gear 84. A second friction cam 36 is fixedly connected to the side of the eighth gear 84 near the first friction cam 35. The spline groove 221 on the outer wall of the second drive rod 22 is located at the interval between the first friction cam 35 and the second friction cam 36. A first friction concave wheel 32, which is frictionally driven by the first friction cam 35 and the second friction cam 36, is slidably sleeved on the outer wall of the second drive rod 22 at the position of the spline groove 221. A first outer retaining ring 33 is fixedly connected to the middle of the first friction concave wheel 32, and the first outer retaining ring 33 is slidably connected to the spline groove 221 on the outer wall of the second drive rod 22. A first retaining bracket 3 is rotatably sleeved on the outer wall of the first outer retaining ring 33. 4. A second support seat 7 is fixedly connected to the top of the hanging plate 2. A second hydraulic push rod 73 is fixedly sleeved on the inner side wall of the second support seat 7. A third friction cam 78 is fixedly connected to the side of the sixth gear 72 away from the fifth gear 71. A spline groove 221 located on the outer wall of the connecting rod 4 is opened at the end of the connecting rod 4. A third friction concave wheel 76 that is frictionally driven with the third friction cam 78 is slidably sleeved on the outer wall of the connecting rod 4 corresponding to the position of the spline groove 221.

A second retaining bracket 74 is rotatably sleeved on the outer side wall of the second outer retaining ring 77. Push plates 75 are fixedly connected to the outer side walls of the first retaining bracket 34 and the second retaining bracket 74. The telescopic ends of the first hydraulic push rod 31 and the second hydraulic push rod 73 are fixedly connected to the outer side walls of the two push plates 75 respectively.

[0039] By adopting the above technical solution, through the friction transmission design between the first friction cam 35 and the second friction cam 36, and the third friction cam 78 and the third friction concave wheel 76, the clutch assembly achieves efficient power transmission and precise clutch control. This not only reduces energy loss but also ensures the smoothness and accuracy of power transmission, enabling the equipment to respond quickly when starting, stopping, or adjusting its working state, thus improving overall work efficiency. The introduction of the first hydraulic push rod 31 and the second hydraulic push rod 73 allows the clutch assembly to intelligently and automatically adjust according to actual needs. By controlling the extension and retraction of the hydraulic push rods, the positions of the first clamp 34 and the second clamp 74 can be precisely controlled. By adjusting the contact pressure and friction between the first friction concave wheel 32 and the third friction concave wheel 76 and the corresponding friction cam, precise control of the clutch is achieved. By adopting a combination of friction transmission and hydraulic control, the clutch assembly reduces direct contact and wear between mechanical parts during operation, which not only reduces equipment maintenance costs but also extends the service life of key components. In addition, the design of the spline groove 221 provides good guidance and support for the sliding connection, further reducing friction and wear between components. The intelligent automatic adjustment function of the integrated assembly allows operators to complete clutch operation without direct contact with the equipment, reducing operational difficulty and safety risks.

[0040] For the lifting and lowering of the suspended platform 2 and the clamping of the main corrugated pipe 111: the output end of the first motor 11 drives the first drive rod 12 and the first synchronous pulley 16 to rotate. During the rotation, the first synchronous belt 17 drives the auxiliary drive rod 15 to rotate synchronously. The first drive rod 12 and the auxiliary drive rod 15 will drive the cable roller 14 to rotate during the rotation. Due to gravity, the suspended platform 2 will move downward. At this time, the suspended platform 2 can be moved downward by the cooperation of the hook 142 and the hook 143. When it is necessary to raise the suspended platform 2... Simply reverse the first drive rod 12 and the auxiliary drive rod 15. Since the main bellows 111 needs to be fitted into the end of the auxiliary bellows 112, and the end size of the auxiliary bellows 112 is larger than that of the main bellows 111, in order to completely clean the outer wall of the main bellows 111, the center of the main bellows 111 and the center of the auxiliary bellows 112 need to be aligned using the clamping assembly. At this time, the user connects the power source of the connecting rod 4 through the clutch assembly, and the second motor 21 drives the second drive rod 22 to rotate. During the process, the fifth gear 71 and the sixth gear 72 cooperate, and the kinetic energy of the third friction wheel 76 and the third friction cam 78 is applied, thereby driving the connecting rod 4 and the worm gear 42 to rotate. Since the worm gear 42 meshes with the turbine 43, the turbine 43 drives the threaded rod 44 to rotate. Through the cooperation of the threaded rod 44 and the sleeve 45, the sleeve 45 will drive the second connecting rod 53 to pull the V-shaped connecting rod 55 to bend during the descent. And through the limiting of the first connecting rod 52, the two clamping frames 54 are driven. When the position changes, when the sleeve 45 rises again, the two clamping frames 54 will move towards the center simultaneously to clamp the main bellows 111. Since the clamping position of the clamping frame 54 is located on the outer wall of the main bellows 111, it is necessary to use the lifting assembly to move the hanging plate 2 upward and to the center of the auxiliary bellows 112. Then, the user disconnects the kinetic energy of the connecting rod 4 through the clutch assembly. Since there is a self-locking property between the threaded rod 44 and the sleeve 45, the clamping force will not be insufficient due to the lack of power. For cleaning the main bellows 111 and auxiliary bellows 112: The user connects the kinetic energy of the eighth gear 84 through the clutch assembly. When the second drive rod 22 rotates, the eighth gear 84 meshes with the seventh gear 8, and drives the sprocket 82 to rotate through the extension rod 81. Since there is a corresponding sprocket 82 at the bottom of the hanging plate 2, the sprocket 82 drives the chain 83 to rotate. Because the cleaning component works in conjunction with the chain 83, when the chain 83 rotates, it can drive the cleaning component to move under the drive of the connecting frame 95. During the movement... During the process, the first outer support 61 and the second gear 612 will slide on the outer wall of the rotating rod 6, with the main slide rail 24 serving as the main load-bearing force and the chain 83 serving as the driving force. When the cleaning assembly moves to the middle of the main bellows 111 and the auxiliary bellows 112, the user can adjust the position of the cleaning sponge 944 on the outer wall of the main bellows 111 so that it contacts the outer wall of the main bellows 111, while the cleaning cotton swab 104 is adjusted to be located on the inner wall of the auxiliary bellows 112. The adjustment process is achieved by rotating the first torque rod 943 and the second torque rod 102, respectively. This is achieved by causing the first torque rod 943 to rotate in relation to the threaded rotation of the outer plate 941, thereby changing the position of the cleaning sponge 944. Then, the second drive rod 22 is controlled to drive the second synchronous wheel 26, which in turn drives the lower rotating rod 6 to rotate, thereby engaging the first gear 611 and the second gear 612. Since the first gear 611 is connected to the third gear 65 via the support rod 64, when the third gear 65 rotates, it drives the fourth gears 66 on both sides to rotate. The ends of the fourth gears 66 are all connected to the internal gear 93. The two internal gears 93 mesh with the first external gear 94 and the second external gear 10 respectively, so the first external gear 94 and the second external gear 10 will rotate. The first external gear 94 and the second external gear 10 are both rotated and sleeved on the ends of the two circular chucks 9. When the first external gear 94 and the second external gear 10 rotate, the outer wall of the main bellows 111 and the inner wall of the auxiliary bellows 112 can be cleaned by the cleaning sponge 944 and the cleaning cotton swab 104, so as to avoid the presence of impurities inside during the docking process, which may cause gaps. Regarding the use of the clutch assembly: For the kinetic energy input of the connecting rod 4, the telescopic end of the second hydraulic push rod 73 will drive the second clamp 74 to move via the push plate 75. The second clamp 74 is engaged with the outside of the second outer clamp 77. Therefore, when the second clamp 74 moves, it can drive the third friction wheel 76 to move via the second outer clamp 77, thereby achieving contact with the third friction cam 78. Since the third friction wheel 76 and the second outer clamp 77 are slidably connected to the connecting rod 4, and the sixth gear 72 and the third friction cam 78 are rotatably sleeved with the end of the connecting rod 4, when the third friction cam 78 contacts the third friction wheel 76, it can drive the connecting rod 4 to rotate through friction. During the operation of the clamping assembly, the first clamp... 34 will drive the first friction concave wheel 32 to be positioned at the interval between the second friction cam 36 and the first friction cam 35 through the first outer retaining ring 33, without contacting either of them. For the kinetic energy input of the conveying component, under the drive of the first hydraulic push rod 31, the first card holder 34 will drive the first friction concave wheel 32 to contact the second friction cam 36 through the first outer retaining ring 33. At this time, the eighth gear 84 will rotate under the drive of the second drive rod 22. For the kinetic energy input of the cleaning component, the telescopic end of the first hydraulic push rod 31 will drive the first card holder 34 and the first outer retaining ring 33 to move. At this time, the first friction concave wheel 32 will contact the first friction cam 35, realizing the rotation of the second synchronous wheel 26, thereby achieving the purpose of driving the rotating rod 6 to rotate through the second synchronous belt 27.
