Description

Technical Field

[0001] The invention relates to the technical field of corrugated pipe installation, in particular to a pipe head cleaning device used for MPVE double-wall corrugated pipe installation. Background Art

[0002] MPVE double-wall corrugated pipe is just a new type of pipe, which is made by blending polyethylene resin, polyvinyl chloride resin, compatibilizer and other polymers. This pipe combines the toughness of polyethylene and the rigidity of polyvinyl chloride, and has the advantages of oxidation resistance and flame retardancy. The design of MPVE double-wall corrugated pipe makes up for the defects of polyethylene corrugated pipe, which has good toughness but insufficient rigidity and rapid oxidation, and overcomes the shortcomings of polyvinyl chloride, which has good rigidity but poor toughness. MPVE double-wall corrugated pipe also has the advantages of convenient installation and transportation, good sealing, and excellent hydraulic properties. Its light weight and good flexibility make the pipe more labor-saving during transportation and installation, while reducing the difficulty and cost of construction. The flexible interface design of the rubber ring socket connection ensures the sealing of the pipeline system and effectively prevents the occurrence of leakage problems.

[0003] In the current pipeline connection and cleaning technology, especially for pipes with special structures such as bellows, the cleaning work before connection is particularly important. The existing cleaning methods and technologies have significant deficiencies in dealing with the cleaning task before the two sections of bellows are connected. Traditional cleaning methods often rely on manual handheld cleaning tools for operation. Manual cleaning often makes it difficult to accurately control the cleaning force and range, resulting in uneven cleaning effects. For bellows, which have complex geometric shapes and multi-layer structures, manual cleaning is difficult to penetrate into every tiny gap and corner, leaving blind spots for cleaning, increasing the risk of leakage after the pipeline is connected. Moreover, when the two bellows are docked, since the pipe head of one of the bellows is in the installation position, it needs to be manually lifted by the staff, and then the part in contact with the soil can be cleaned. Once the bellows is put down, it will be contaminated with dust, affecting the installation and docking of the bellows head.

[0020] See also Figure 1 - Figure 5The present invention provides a technical solution: a pipe head cleaning device for MPVE double-wall corrugated pipe installation, comprising a moving platform 1, a hanging plate 2, and a main corrugated pipe 111 and an auxiliary corrugated pipe 112 connected to each other, the main corrugated pipe 111 and the auxiliary corrugated pipe 112 are both placed below the hanging plate 2, and the two are arranged relatively, the inner top end of the moving platform 1 is provided with a lifting component for driving the hanging plate 2 to move up and down, the upper top end of the hanging plate 2 is provided with a driving component as a power source, the lower bottom end of the hanging plate 2 is provided with a cleaning component for removing dust from the main corrugated pipe 111 and the auxiliary corrugated pipe 112, the lower bottom end of the hanging plate 2 is provided with a conveying component for driving the cleaning component to move, the lower bottom end of the hanging plate 2 is located on one side of the cleaning component and is provided with a clamping component for limiting the main corrugated pipe 111, and the upper top end of the hanging plate 2 is provided with a clutch component for respectively controlling the operation of the cleaning component, the clamping component and the conveying component.

[0021] By adopting the above technical scheme, through the cleaning component integrated under the hanging plate 2, the device can automatically remove dust from the pipe heads of the main bellows 111 and the auxiliary bellows 112. Under the strong drive of the driving component, the cleaning component, combined with the precise movement control of the conveying component, can completely remove dust and impurities on 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 pipeline connection. The clamping component can firmly limit the main bellows 111 before the cleaning operation to ensure that it maintains a stable position without displacement or shaking during the entire cleaning process, which not only improves the efficiency of the cleaning operation, but also ensures the consistency of the cleaning effect, and avoids the cleaning blind spot caused by the change of the pipe head position. The setting of the lifting component enables the hanging plate 2 and all the working components thereunder to move up and down as needed, so as to easily adapt to the pipeline installation environment of different heights and positions. In addition, the introduction of the clutch component enables the operator to independently control the working status of the cleaning component, the clamping component and the conveying component as needed, realizing a flexible and changeable operation mode, and further improving the adaptability and practicality of the device.

[0022] See also Figure 1 - Figure 3The lifting assembly includes a first motor 11 fixedly connected to the inner top of the moving platform 1, the output end of the first motor 11 is fixedly connected to the first driving rod 12, the inner top of the moving platform 1 is provided with an auxiliary driving rod 15 at one side of the first driving rod 12, the outer walls of the first driving rod 12 and the auxiliary driving rod 15 are fixedly sleeved with a first synchronous wheel 16, the outer wall of the first synchronous wheel 16 is sleeved with a first synchronous belt 17, the ends of the first driving rod 12 and the auxiliary driving rod 15 are fixedly connected with a first bearing seat 13, and the upper top of the first bearing seat 13 is fixedly connected to the inner top of the moving platform 1, the outer surfaces of the first driving rod 12 and the auxiliary driving rod 15 are fixedly sleeved with two pairs of cable rollers 14, the outer walls of the cable rollers 14 are wrapped with a sling 141, the end of the sling 141 is fixedly connected with a hook 142, and the upper top of the hanging plate 2 is symmetrically fixedly connected with a hook 143 fixedly sleeved with the hook 142.

[0023] By adopting the above technical solution, the first motor 11 is used as a power source to directly drive the first driving rod 12 to rotate, and then the transmission effect of the first synchronous wheel 16 and the first synchronous belt 17 is utilized to drive the auxiliary driving rod 15 to rotate synchronously. The design of double-rod synchronous drive ensures the smoothness and uniformity of the lifting process, effectively avoids the vibration or offset problem caused by a single driving point, and improves the stability of the lifting operation. The ingenious design of the cable roller 14 enables the sling 141 to be freely extended and retracted as needed, thereby realizing precise control of the lifting height of the hanging plate 2. The two pairs of cable rollers 14 The setting not only enhances the carrying capacity and stability of the cable system, but also ensures the balance of the hanger plate 2 during the lifting process, and prevents the tilting phenomenon caused by uneven force on one side. The sling 141 is fixedly connected with the hook 143 on the hanger plate 2 through the hook 142. This connection method is simple and firm, and can withstand greater tension and impact force, ensuring the safety of the hanger plate 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] See also Figure 3 and Figure 5 The driving 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 driving rod 22, the end of the second driving rod 22 is fixedly connected to a second bearing seat 23 for support, and the lower bottom end of the second bearing seat 23 is fixedly connected to the upper top of the hanging plate 2.

[0025] By adopting the above technical solution, the second motor 21 serves as the core power source to directly drive the second drive rod 22 to rotate, thereby realizing efficient power transmission. The direct drive mode reduces the loss in the energy conversion process, ensures the stability and continuity of the power output, and provides strong support for subsequent cleaning, clamping and conveying operations. The second drive rod 22 is firmly mounted on the hanging plate 2 through the second bearing seat 23. This design not only enhances the overall stability of the drive assembly, but also ensures the coaxiality and precision of the second drive rod 22 during high-speed rotation, thereby avoiding the problem of affecting the power transmission effect due to vibration or offset.

[0026] See also Figure 5 , Fig. 9 and Fig.11 The clamping assembly includes a connecting rod 4 rotatably connected to the top of the hanging plate 2, the outer wall of the connecting rod 4 is fixedly sleeved with two third bearing seats 41 as supports, the lower bottom end of the third bearing seat 41 is fixedly connected to the upper top of the hanging plate 2, the end of the connecting rod 4 is rotatably sleeved with a sixth gear 72, the outer wall of the second driving rod 22 is fixedly sleeved with a fifth gear 71 meshing with the sixth gear 72, the outer wall of the connecting rod 4 is symmetrically fixedly sleeved with a worm 42, the upper top of the hanging plate 2 is rotatably connected with a turbine 43 meshing with the worm 42, the lower bottom end of the turbine 43 is fixedly connected with a threaded rod 44, and the threaded rod 44 is rotatably connected to the hanging plate 2, and the threaded rod 44 A sleeve 45 is threadedly sleeved on the outer wall, and the outer wall of the sleeve 45 is symmetrically rotationally connected to one end of the second connecting rod 53, and the lower bottom end of the hanging plate 2 is symmetrically fixedly connected to the fixed bracket 5, and the outer wall of the fixed bracket 5 is fixedly connected to the side bracket 51 close to the threaded rod 44, and the inner wall of the side bracket 51 is symmetrically rotationally connected to the V-shaped connecting rod 55, and the other end of the second connecting rod 53 is rotationally connected to the center of the outer wall of the V-shaped connecting rod 55, and the end of the V-shaped connecting rod 55 is rotationally connected to a clamping frame 54 for limiting the main bellows 111, and the lower bottom end of the fixed bracket 5 is rotationally connected to the first connecting rod 52, and the end of the first connecting rod 52 is rotationally connected to the inner wall of the clamping frame 54.

[0027] By adopting the above technical solution, the meshing transmission between the second driving rod 22 and the fifth gear 71 and the sixth gear 72 realizes the efficient transmission of power from the driving assembly to the clamping assembly. The meshing transmission between the worm 42 and the turbine 43 drives the threaded rod 44 to rotate, thereby driving the sleeve 45 to move along the thread direction, ensuring the synchronization and accuracy of the clamping frame 54 during the opening and closing process, and can accurately clamp the main bellows 111 to prevent it from moving or shaking during the cleaning process. Since the threaded rod 44 and the sleeve 45 are threadedly connected, when the sleeve 45 moves, a certain self-locking force can be generated, so that the clamping frame 54 is in the clamping process. To maintain 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 connecting rod 52, the second connecting rod 53 and the V-shaped connecting rod 55. In addition, the design of the V-shaped connecting rod 55 enables 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 transmission ratio of the worm 42 and the turbine 43 is large, and it has self-locking properties, which can maintain the clamping state in the event of power failure or failure to prevent accidental loosening.

[0028] See also Figure 4 - Figure 7 The conveying assembly includes a sprocket 82 symmetrically rotatably connected to the lower end of the hanging plate 2, wherein the end of one of the sprockets 82 is fixedly connected to an extension rod 81, and the end of the extension rod 81 is fixedly sleeved with a seventh gear 8 for transmission, the outer wall of the second driving rod 22 is rotatably sleeved with an eighth gear 84 meshing with the seventh gear 8 for transmission, and the outer wall of the sprocket 82 is meshingly sleeved with a chain 83.

[0029] By adopting the above technical solution, the conveying component realizes direct and efficient transmission of power from the driving component to the conveying component through the ingenious connection of the second driving rod 22 with the eighth gear 84, the seventh gear 8 and the extension rod 81, reducing the loss of energy in the transmission process and ensuring 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 large carrying capacity, smooth transmission, and wear resistance. Even when running at high speed or bearing a large load, it can maintain a stable conveying effect, effectively avoiding damage caused by asynchronous or fluctuating conveying.

[0031] By adopting the above technical scheme, the cleaning component cleverly combines the main cleaning structure and the auxiliary cleaning structure, and cleans the outer wall of the main bellows 111 and the inner wall of the auxiliary bellows 112 respectively. The double cleaning mechanism ensures comprehensive coverage of the inner and outer surfaces of the bellows, effectively removes dirt and impurities, and improves the cleaning effect. The transmission structure realizes efficient power transmission from the second drive rod 22 to the rotating rod 6 through the meshing transmission of the second synchronous wheel 26 and the second synchronous belt 27.

[0033] By adopting the above technical scheme, the main cleaning structure ensures the synchronous movement of various components during the cleaning process through the meshing of the first outer gear 94 and the inner gear 93, and the double meshing transmission of the first outer gear 94 and the gear ring 92, effectively avoiding the problem of uneven cleaning caused by asynchronous transmission, and improving the cleaning efficiency and quality. The first outer gear 94, under the guidance of the gear ring 92, can rotate along the gear ring 92, and then adaptively adjust the position so that the cleaning sponge 944 can be close to the outer wall of the bellows 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 bellows can be conveniently adjusted, thereby ensuring the cleaning effect while avoiding damage to the surface of the bellows. The cleaning sponge 944, as a cleaning medium that directly contacts the outer wall of the bellows, can be replaced according to different cleaning needs.

[0035] By adopting the above technical scheme, the auxiliary cleaning structure realizes the precise positioning of the inner wall of the auxiliary bellows 112 through the meshing transmission of the second outer gear 10 and the inner gear 93, ensuring that the cleaning cotton swab 104 can penetrate into the interior of the bellows and thoroughly clean the hard-to-reach corners and gaps, effectively removing the dirt and impurities on 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 bellows 112 can be easily adjusted. The sliding connection design between the auxiliary plate 103 and the cleaning cotton swab 104 enables the cleaning cotton swab to flexibly adjust its position as the shape of the inner wall of the bellows changes, which not only improves the flexibility of cleaning, but also ensures the close fit between the cotton swab and the inner wall during cleaning, further improving the cleaning effect. During use, the cleaning cotton swab 104 can be inserted into the interior of the auxiliary bellows 112 by moving the mobile platform 1, and then the mobile platform 1 is moved, and the main bellows 111 is clamped by the clamping assembly.

By slidingly connecting inside the slide rail, these components can move smoothly along the predetermined trajectory, reducing the friction and wear caused by position offset, which not only reduces the maintenance cost, but also improves the overall performance and reliability of the equipment. The solid structure of the main slide rail 24 and the auxiliary slide rail 25 provides strong support for the entire cleaning assembly, not only bearing the weight and force from the support frame 91 and the first outer support frame 61, but also through the stable guiding effect, ensuring the stability and precision of the entire assembly during operation.

By controlling the extension and retraction of the hydraulic push rod, the position of the first bracket 34 and the second bracket 74 can be accurately controlled, thereby achieving 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 cams, precise control of the clutch is achieved. By combining friction transmission and hydraulic control, the clutch component reduces direct contact and wear between mechanical parts during operation, which not only reduces the maintenance cost of the equipment, but also extends the service life of key parts.

[0040] For the lifting and lowering of the hanging plate 2 and the clamping of the main bellows 111: the output end of the first motor 11 drives the first drive rod 12 and the first synchronous wheel 16 to rotate, and during the rotation, the auxiliary drive rod 15 will be driven to rotate synchronously through the first synchronous belt 17. The first drive rod 12 and the auxiliary drive rod 15 will drive the cable roller 14 to rotate during the rotation, and the hanging plate 2 will move downward due to the influence of gravity. At this time, the hanging plate 2 can be driven to move downward by the cooperation of the hook 142 and the hook 143. When the hanging plate 2 needs to be raised , it is only necessary to reverse the first drive rod 12 and the auxiliary drive rod 15. Since the main bellows 111 needs to be inserted into the end of the auxiliary bellows 112, and the end size of the auxiliary bellows 112 is larger than the size of the main bellows 111, in order to completely clean the outer wall of the main bellows 111, it is necessary to use a clamping assembly to place the center of the main bellows 111 and the center of the auxiliary bellows 112 at the same position. At this time, the user connects the power source of the connecting rod 4 through the cooperation of 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 with each other, and the kinetic energy of the third friction concave wheel 76 and the third friction cam 78 is connected, so as to drive the connecting rod 4 and the worm 42 to rotate. Since the worm 42 is meshed with the turbine 43, the turbine 43 drives the threaded rod 44 to rotate, and through the cooperation between 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 process of descending, and drive the two clamping frames 54 through the limit of the first connecting rod 52. The position of the main bellows 111 changes. When the sleeve 45 rises again, the two clamping frames 54 will move synchronously to the middle, thereby clamping 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 drive the hanging plate 2 to move up again through the lifting assembly and move it 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 lack of power will not cause insufficient clamping force. For the cleaning of the main bellows 111 and the auxiliary bellows 112: the user connects the kinetic energy of the eighth gear 84 through the clutch assembly. At this time, when the second drive rod 22 rotates, the eighth gear 84 meshes with the seventh gear 8 for transmission, and drives the sprocket 82 to rotate through the extension rod 81. Since a relative sprocket 82 is provided at the bottom end of the hanging plate 2, the sprocket 82 drives the chain 83 to rotate. Since the cleaning assembly is used in conjunction with the chain 83, when the chain 83 rotates, it can drive the cleaning assembly to move under the drive of the connecting frame 95, and in the process of moving During the cleaning process, the first outer support frame 61 and the second gear 612 will slide on the outer wall of the rotating rod 6, and the main slide rail 24 will be used as the main load-bearing force, and the chain 83 will be used as the driving force. When the cleaning component 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 to make it contact with the outer wall of the main bellows 111, and the cleaning cotton stick 104 is adjusted to be located on the inner wall of the auxiliary bellows 112. The adjustment process is respectively performed by rotating the first torque rod 943 and the second torque rod 102 To complete the rotation of the first torque rod 943 and the outer plate 941, the position of the cleaning sponge 944 is changed, and then the second driving rod 22 is controlled to drive the second synchronous wheel 26 to work, which can drive the lower rotating rod 6 to rotate, thereby driving the first gear 611 and the second gear 612 to engage and transmit. Since the first gear 611 is connected to the third gear 65 through the support rod 64, when the third gear 65 rotates, it can drive the fourth gear 66 on both sides to rotate, and the ends of the fourth gear 66 are connected to the inner gear 93. The two inner gears 93 are meshed with the first outer gear 94 and the second outer gear 10 respectively, so the first outer gear 94 and the second outer gear 10 will rotate, and the first outer gear 94 and the second outer gear 10 are both rotatably sleeved on the ends of the two circular chucks 9. When the first outer gear 94 and the second outer 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 situation in which there are impurities inside and cause gaps during the docking process; Regarding the use of the clutch assembly: for the kinetic energy of the connecting rod 4, the telescopic end of the second hydraulic push rod 73 will drive the second clamping frame 74 to move through the push plate 75, and the second clamping frame 74 is clamped on the outside of the second outer clamping ring 77. Therefore, when the second clamping frame 74 moves, it can drive the third friction concave wheel 76 to move through the second outer clamping ring 77, thereby achieving contact with the third friction cam 78. Since the third friction concave wheel 76 and the second outer clamping ring 77 are slidingly 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 concave wheel 76, the friction force can be used to drive the connecting rod 4 to rotate. During the operation of the clamping assembly, the first clamping frame 34 will drive the first friction concave wheel 32 to be located at the interval between the second friction cam 36 and the first friction cam 35 through the first outer retaining ring 33, and will not contact the two. For the kinetic energy access of the conveying component, the first bracket 34 will drive the first friction concave wheel 32 to contact the second friction cam 36 through the first outer retaining ring 33 under the drive of the first hydraulic push rod 31. At this time, the eighth gear 84 is rotated under the drive of the second driving rod 22. For the kinetic energy access of the cleaning component, the telescopic end of the first hydraulic push rod 31 drives the first bracket 34 and the first outer retaining ring 33 to move. At this time, the first friction concave wheel 32 contacts the first friction cam 35 to realize 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.
