Description

Technical Field

[0001] This application relates to the field of lathe technology, and in particular to a multi-station lathe for synchronous machining of pipe ends for scaffolding. Background Technology

[0002] Scaffolding is a temporary structural frame erected in construction to facilitate personnel operation, material stacking, and horizontal transportation. It typically consists of steel pipes, couplers, and scaffold boards, and is used for working at heights, supporting formwork, installing components, or carrying out construction activities such as decoration and maintenance. During the production and processing of scaffolding, the ends of pipes often need to be machined to ensure the flatness, verticality, and dimensional accuracy of the pipe ends, thereby meeting the requirements for subsequent welding, splicing, bolting, or assembly.

[0003] In the prior art, when turning the pipe ends of scaffolding pipes, the pipe is usually first fixed with a clamp, then the cutting tool is brought into contact with the pipe wall, and then the pipe is driven to rotate to complete the turning process.

[0004] However, in batch processing, multiple pipe fittings need to be turned continuously, thus requiring sequential loading of these fittings. Existing loading methods typically include manual loading and robotic arm loading, but both have certain shortcomings: Manual loading is labor-intensive and can easily lead to misalignment or a decrease in loading speed due to fatigue, thus affecting the quality and efficiency of turning.

[0005] When a robotic arm is picking up and loading materials, if the pipes are not neatly arranged, the robotic arm will have difficulty accurately identifying and stably picking up the pipes, which may lead to problems such as picking failure, misalignment, or dropping, resulting in feeding failure or damage to the pipes. At the same time, robotic arms usually need to be used with relatively complex vision recognition or positioning mechanisms, which result in high equipment costs and complex control programs, making them less suitable for small to medium batches or irregularly arranged pipes.

[0006] In addition, regardless of whether manual feeding or robotic arm clamping is used, it is difficult to ensure the consistency of the relative position between the pipe end and the fixture during continuous processing. This can easily cause problems such as uneven pipe end turning, chamfer or bevel size fluctuations, which in turn affect the quality of subsequent welding, splicing or assembly.

[0018] The beneficial effects of this invention are as follows: 1. The multi-station synchronous pipe end processing lathe of the present invention can sequentially extract and machine multiple pipes under the action of the pipe arrangement assembly and the pipe picking and tool setting assembly, thereby realizing continuous automatic feeding and multi-station synchronous processing. Compared with the prior art, through the cooperation of structures such as the feeding frame, partition, height limit plate and electromagnetic vibrator, multiple pipes can be automatically dropped into each pipe channel after being poured in at the same time and transported to the pipe picking station in sequence. There is no need for manual alignment of each pipe, which reduces labor intensity and avoids inaccurate alignment and reduced feeding speed due to fatigue. At the same time, even if the initial arrangement of pipes is not neat, stable feeding can be achieved through vibration feeding and channel limiting, avoiding problems such as difficulty in identification, failure of gripping, deviation or drop when gripping by the robot. Moreover, there is no need for complex vision recognition or positioning mechanism, the equipment cost is low, the control is simple, and the applicability is stronger.

[0019] Furthermore, the center-to-center distance between adjacent electric chucks matches the center-to-center distance between pipe fittings within adjacent pipe channels, ensuring consistent relative positions between the pipe fitting ends and the clamps. This avoids uneven pipe end machining, chamfering, or beveling dimension fluctuations, which improves the quality of subsequent welding, splicing, or assembly. It effectively solves problems such as high labor intensity, fatigue, and inaccurate alignment associated with manual material handling, as well as difficulties in identification, clamping failures, high equipment costs, and complex control when using robotic arms for material handling with non-aligned pipe fittings. It also ensures consistency and efficiency in pipe end machining, making it suitable for mass production of scaffolding pipe fittings.

[0020] 2. The multi-station synchronous pipe end processing lathe of the present invention utilizes a rotary friction pipe-laying auxiliary component. When the loading frame vibrates and moves multiple pipes within the rectangular frame, multiple turntables can be intermittently driven to rotate. As the turntables rotate, their surfaces contact the pipes horizontally positioned at the top of the partition, generating friction. This causes the pipes to move or rotate along the top of the partition, gradually adjusting them to a state where they coincide with or nearly coincide with the center line of the pipe channel. This makes it easier for the pipes to fall into the corresponding pipe channel, avoiding the problem of pipes remaining on the top of the partition for extended periods due to incorrect orientation and failing to fall into the pipe channel on their own, thus improving the reliability of loading.

[0021] 3. The multi-station synchronous pipe end machining lathe of the present invention utilizes a pipe collection auxiliary mechanism. A cylindrical structure is formed by multiple polymer plates and multiple filler fabrics. After a set of pipes is machined, the pipes fall into the cylindrical structure. Multiple polymer plates simultaneously approach the axis of the fixed disc, while the filler fabric is wound up by the cloth rollers under the torque of the spring, causing the cylindrical structure to continuously shrink in size. At this time, multiple pipes inside the cylindrical structure are gradually gathered together by the polymer plates and the wound filler fabric, causing the pipes originally leaning against the inner wall of the cylindrical structure to continuously converge towards the center of the cylinder. During the gathering process, the pipes automatically adjust their posture, ultimately arranging them neatly along the axial direction of the cylindrical structure and tightly adhering to each other, forming a bundle of pipes that is easy to bundle. Personnel can directly bundle the ends of the bundle of pipes uniformly, eliminating the need for individual sorting and alignment of each pipe, reducing manual labor intensity. Furthermore, the sorting, alignment, and bundling processes can match the high efficiency of the aforementioned multi-station synchronous machining, improving overall processing efficiency.

[0022] Furthermore, during the gathering process, if a pipe gets stuck, the friction roller rotates, bringing it into contact with a pipe on either side of the cylinder structure. The friction force causes the pipe to shift, breaking the jamming and allowing the pipe to continue gathering towards the center of the cylinder. This further improves the reliability and efficiency of pipe gathering, preventing problems such as the cylinder structure failing to gather properly or the pipe bundle becoming loose or misaligned due to pipe jamming.

[0023] 4. The multi-station synchronous pipe end processing lathe of the present invention can adjust the distance between the lifting plate and the cylinder opening according to the length of the pipe, so that the distance is adapted to the length of the pipe. This ensures that after the pipe is lowered into the cylinder structure, its end is located near or extends out of the cylinder opening, facilitating uniform binding of the pipe end by personnel, while preventing accidental fall due to excessive extension of the pipe end. Furthermore, when the dimensions of the cylinder structure change, the fitting rod will always be in contact with the surface of the polymer plate under the action of the spring. Multiple take-up and undo wheels rotate simultaneously to wind and unwind the wire rope, keeping the portion of the wire rope outside the mounting shell taut at all times. The wire rope fills the gap between the lifting plate and the polymer plate to support the pipe. Thus, during the closing or enlarging process of the cylinder structure, the gap between the lifting plate and the polymer plate is always effectively sealed by the wire rope, preventing the pipe end from protruding from the gap. This ensures that the pipe can stand stably in the cylinder structure and neatly gather with the closing of the cylinder structure, facilitating subsequent uniform binding and transportation.

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] Example 1: like Figure 1 , Figure 2 , Figure 4 , Figure 7 As shown, a multi-station pipe end synchronous processing lathe for scaffolding includes a lathe body 1 and a plurality of tool holders 31 arranged equidistantly in the transverse direction. The tool holders 31 are provided with turning tools 30. The lathe body 1 is provided with a pipe arrangement assembly and a pipe picking and tool setting assembly. The pipe assembly includes a feeding frame 3, with multiple partitions 8 evenly spaced along the upper edge of the feeding frame 3. The bottom of the partitions 8 is attached to the inner bottom surface of the feeding frame 3, and the multiple partitions 8 cooperate with each other to form multiple pipe channels. The tube picking and tool setting assembly includes multiple adjusting discs 27 equidistantly arranged in the transverse direction. An electric chuck 29 is rotatably mounted on the adjusting discs 27. The tube picking and tool setting assembly also includes a displacement structure for adjusting the orientation and angle of the multiple electric chucks 29. A vision sensor 5 is installed on the main body 1 of the lathe.

[0028] like Figure 4 As shown, the lathe body 1 is equipped with a vibration generating structure; The vibration generating structure includes multiple support columns 4 fixed on the lathe body 1, with spring dampers 17 on the support columns 4, and a loading frame 3 fixed on the piston end of multiple spring dampers 17. An electromagnetic vibrator 16 is installed on the loading frame 3.

[0029] like Figure 4 As shown, a variable pitch slide 2 56 is fixedly provided on the feeding frame 3. The variable pitch slide 2 56 is provided with multiple sliders that can move simultaneously, and each partition 8 is fixedly provided on a slider. A baffle 2 is fixedly provided on one side partition 8.

[0030] like Figure 4 As shown, a height limit plate 18 is slidably mounted vertically on one side of the feeding frame 3. A cylinder 7 is mounted on the feeding frame 3 to drive the height limit plate 18 to rise and fall. A stop bar 9 is slidably mounted on one side of the bottom of the feeding frame 3. A cylinder 10 is mounted on the feeding frame 3 to drive the stop bar 9 to slide.

[0031] like Figures 6-8 As shown, the lathe body 1 is provided with a lead screw linear module 3 55. The moving end of the lead screw linear module 3 55 is fixedly provided with a transverse frame 6. The transverse frame 6 is provided with a lead screw linear module 22. The moving end of the lead screw linear module 22 is fixedly provided with a lifting frame 24. The lifting frame 24 is rotatably provided with a variable pitch slide 1 26. The variable pitch slide 1 26 is provided with multiple sliders that can move simultaneously. Each adjustment plate 27 is fixedly provided on a slider. The adjustment plate 27 is provided with a motor 28 for driving the electric chuck 29 to rotate. The lifting frame 24 is provided with a motor 25 for driving the variable pitch slide 1 26 to rotate. The lathe body 1 is provided with a bracket 19 that slides laterally. Multiple tool holders 31 are fixedly provided on the bracket 19. The lathe body 1 is provided with a cylinder 3 20. The piston end of the cylinder 3 20 is fixedly connected to one side of the bracket 19.

[0032] Specifically, this embodiment is applied to the turning of pipe fittings of the same specifications in the same batch. Since multiple partitions 8 cooperate to form multiple pipe fitting channels, the variable pitch slide 2 56 can be activated according to the pipe fitting diameter. The slider at the end of the variable pitch slide 2 56 remains stationary, while the other sliders move synchronously. This causes the multiple partitions 8 to move simultaneously, changing the width of the multiple pipe fitting channels simultaneously, and ensuring that the width of each pipe fitting channel remains the same until the pipe fitting channel width matches the pipe fitting diameter. Using one slider as a reference to move the other multiple sliders simultaneously is an existing variable pitch technology, which will not be elaborated upon here.

[0033] Furthermore, when the partition 8 moves, the baffle 2 also moves synchronously. The feeding frame 3, the baffle 2, and the height limiting plate 18 cooperate to form a rectangular frame above the multiple pipe channels. Then, the cylinder 7 drives the height limiting plate 18 to rise and fall, adjusting the distance between the bottom edge of the height limiting plate 18 and the inner bottom surface of the feeding frame 3, and making the distance match the diameter of the pipe.

[0034] After completing the above adjustments, the multiple pipes to be machined are poured into the rectangular frame, and the electromagnetic vibrator 16 is activated. The electromagnetic vibrator 16, in conjunction with multiple spring dampers 17, causes the loading frame 3 to vibrate. The multiple pipes in the rectangular frame will then continuously move. When the pipe's axis coincides with the center line of the pipe channel, the pipe will fall into the pipe channel; otherwise, the pipe will remain in the rectangular frame due to the obstruction at the top of the partition 8. As the loading frame 3 continues to vibrate, the multiple pipes will randomly fall into the various pipe channels until the rectangular frame is emptied. Furthermore, when a pipe contacts the inner bottom surface of the loading frame 3, due to the inclined arrangement of the inner bottom surface, the pipe will slide down along the inner bottom surface of the loading frame 3. Furthermore, since the distance between the bottom edge of the height restriction plate 18 and the inner bottom surface of the loading frame 3 is adapted to the diameter of the pipe, only one pipe can pass under the height restriction plate 18 at a time. However, the pipe standing in the pipe channel will tilt under the vibration of the loading frame 3, and will not be stuck at the height restriction plate 18 due to standing up.

[0035] When the pipe falls to the end of the pipe channel, it will be blocked by the stop bar 9. At this time, the vision sensor 5 can detect that the pipe is located at the end of the pipe channel. Then, the lead screw linear module 3 55 drives the transverse frame 6 to move laterally. At the same time, the lead screw linear module 22 drives the lifting frame 24 to rise and fall. Finally, the variable pitch slide 1 26 is started again. Similarly, the electric chuck 29 located at the end of the variable pitch slide 1 26 remains stationary, and the other adjustment plates 27 move at the same time, so that the distance between adjacent electric chucks 29 changes, and the center distance between adjacent electric chucks 29 is matched with the center distance between the pipes in the adjacent pipe channel.

[0036] Subsequently, cylinder 210 drives the stop lever 9 to slide, moving it away from the pipe fitting in the pipe channel. The pipe fitting then continues to slide down and is fitted onto the clamping end of the electric chuck 29. Next, multiple jaws on the electric chuck 29 move radially simultaneously and come into contact with the inner wall of the pipe fitting, thus securing it in place. Furthermore, the control system activates the corresponding electric chuck 29 based on information obtained from the vision sensor 5. If there is no pipe fitting in a certain pipe channel, the corresponding electric chuck 29 will not operate.

[0037] Once the pipe fitting is secured by the electric chuck 29, the electric chuck 29 is driven to move laterally and descend again. Under the combined movement of the electric chuck 29 moving laterally and descending, the pipe fitting can be pulled out along the length of the pipe fitting channel. When the secured pipe fitting is about to completely detach from the pipe fitting channel, the cylinder 2 10 drives the stop lever 9 to reset, pressing down the subsequent pipe fittings to prevent them from falling out prematurely. Thus, one pipe retrieval operation is completed.

[0038] Next, motor 25 drives the variable-pitch slide 26 to rotate, synchronously converting the fixed pipe fittings to a horizontal position. Then, the variable-pitch slide 26 is used again to adjust the spacing between adjacent pipe fittings, ensuring the center distance between adjacent pipe fittings matches the spacing between adjacent turning tools 30. At this point, the multiple turning tools 30 are aligned with the inner cavities of the multiple pipe fittings. Then, the multiple pipe fittings are driven to simultaneously approach the turning tools 30 and move to designated positions. Finally, cylinder 20 drives the bracket 19 to move laterally, causing the multiple turning tools 30 to move laterally synchronously, thus aligning each turning tool 30 with the designated position on the pipe end of the corresponding pipe fitting. Subsequently, motor 28 drives the electric chuck 29 to rotate, allowing the turning tools 30 to turn the pipe ends, thereby achieving multi-station synchronous processing.

[0039] Once a batch of pipe fittings has been machined, the electric chuck 29 releases the fittings, and personnel can use a container to collect the fallen fittings.

[0040] By repeating the above operations, multiple pipes can be sequentially removed and machined under the action of the pipe arrangement assembly and the pipe picking and tool setting assembly, thereby achieving continuous automatic feeding and multi-station synchronous processing. Compared with the existing technology, through the cooperation of the feeding frame 3, partition 8, height limit plate 18 and electromagnetic vibrator 16, multiple pipes can be automatically dropped into each pipe channel after being poured in at the same time and then transported to the pipe picking station in sequence. There is no need for manual alignment of each pipe, which reduces labor intensity and avoids inaccurate alignment and reduced feeding speed due to fatigue. At the same time, even if the pipes are initially not neatly arranged, stable feeding can be achieved through vibration feeding and channel limiting, avoiding problems such as difficulty in identification, failure to pick up, misalignment or dropping when the robot is gripping. Moreover, there is no need for complex vision recognition or positioning mechanisms, the equipment cost is low, the control is simple, and the applicability is stronger.

[0041] Furthermore, the center distance between adjacent electric chucks 29 is matched with the center distance between adjacent pipe fittings in the pipe fitting channel, ensuring that the relative position of the pipe fitting end and the clamp is consistent. This avoids uneven pipe end machining, chamfering, or beveling dimension fluctuations, which is beneficial to improving the quality of subsequent welding, splicing, or assembly. In summary, this embodiment effectively solves the problems of high labor intensity, easy fatigue, and inaccurate alignment of existing manual material feeding, as well as difficulties in identification, clamping failure, high equipment cost, and complex control when the pipe fittings are not neatly arranged by the robotic arm. It also ensures the consistency and processing efficiency of pipe end machining and is suitable for the mass production of scaffolding pipe fittings.

[0042] Example 2: like Figure 3 and Figure 5 As shown, a rotary friction pipe-laying auxiliary assembly is provided on the partition plate 8; The rotary friction pipe auxiliary assembly includes multiple turntables 11 arranged laterally and rotatably mounted on the top of the partition plate 8. A worm gear 12 is fixedly sleeved on one end of each turntable 11. A worm 15 is rotatably mounted on the partition plate 8. The worm 15 has multiple worm teeth, and each worm tooth meshes with the corresponding worm gear 12. A motor 14 is mounted on the partition plate 8 to drive the worm 15 to rotate.

[0043] Specifically, in the above embodiments, in order to adjust the pipe fittings to a state that facilitates clamping, multiple pipe fitting channels are provided. At the same time, the feeding frame 3 continuously vibrates to make the pipe fittings fall into the pipe fitting channels.

[0044] However, adjusting the pipe to the correct orientation solely through vibration is highly random and can easily result in the pipe remaining horizontally on top of the partition 8 and failing to fall into the pipe channel for an extended period. This is especially true when the pipe is nearly parallel to the center line of the pipe channel but at a certain angle, the pipe is easily blocked by the top of the partition 8 and bounces repeatedly, making it difficult for it to adjust itself to coincide with the center line of the pipe channel. This leads to reduced feeding efficiency and may even result in the pipe accumulating within the rectangular frame and the channel being partially empty.

[0045] To address the aforementioned issues, this embodiment incorporates a rotary friction-type pipe-laying auxiliary assembly on the partition 8. When the feeding frame 3 vibrates and causes multiple pipes to move within the rectangular frame, motor 6 14 can be intermittently activated. Motor 6 14 drives worm gear 15 to rotate. Since the multiple worm teeth on worm gear 15 mesh with each worm wheel 12, the rotation of worm gear 15 simultaneously drives multiple turntables 11 to rotate. When the turntables 11 rotate, their surfaces contact the pipes horizontally positioned at the top of the partition 8, generating friction on the pipes. This causes the pipes to move or rotate along the top of the partition 8, gradually adjusting them to a state where they coincide with or nearly coincide with the center line of the pipe channel. This makes it easier for the pipes to fall into the corresponding pipe channel, avoiding the problem of pipes remaining on the top of the partition 8 for extended periods due to incorrect orientation and failing to fall into the pipe channel on their own, thus improving the reliability of the feeding process.

Multiple limiting rods 42 are evenly distributed and fixedly connected to the fixed plate 40 in the circumferential direction. A radial rod 34 slides horizontally through the limiting rods 42. A polymer plate 32 is fixedly connected to one end of the radial rod 34 near the axis of the fixed plate 40. A cloth roller 54 is rotatably mounted inside the polymer plate 32. A filling cloth 33 is wound on the cloth roller 54. A strip-shaped through hole is provided on the side wall of the polymer plate 32 for the filling cloth 33 to pass through. The end of the filling cloth 33 is fixedly mounted on another adjacent polymer plate 32.

[0047] like Figure 9 As shown, a cylinder 38 is fixedly mounted on the fixed plate 40. The piston end of the cylinder 38 is fixedly connected to the bottom of the lifting plate 43. A threaded rod 41 is rotatably mounted on the fixed plate 40. A connecting ring 36 is threadedly connected to the threaded rod 41. Multiple connecting rods 35 are evenly distributed and rotatably connected along the circumference of the connecting ring 36. The end of each connecting rod 35 away from the connecting ring 36 is rotatably connected to the end of the corresponding radial rod 34. A motor 39 is mounted on the fixed plate 40 to drive the threaded rod 41 to rotate.

[0048] like Figure 11 , Figure 12 , Figure 13 , Figure 16 , Figure 17 As shown, the lifting plate 43 has multiple circumferential grooves, and each groove has a sliding contact rod 49. One end of the contact rod 49 is fixedly connected to a spring 46, and the other end of the spring 46 is fixedly connected to the inner wall of the groove. The end of the contact rod 49 is in contact with the corresponding polymer plate 32. A mounting shell 48 is fixedly mounted on the contact rod 49. A take-up and release wheel 53 is rotatably mounted inside the mounting shell 48. A steel wire rope 47 is wound on the take-up and release wheel 53. A hole is opened on the mounting shell 48 for the steel wire rope 47 to pass through. The end of the steel wire rope 47 located outside the mounting shell 48 is fixedly connected to the outer wall of another adjacent mounting shell 48. A worm gear 50 is fixedly mounted on one end of the take-up and release wheel 53. A worm gear 51 is rotatably mounted inside the contact rod 49. The worm gear 51 has multiple worm teeth, and each worm tooth meshes with the corresponding worm gear 50. A motor 52 is provided inside the contact rod 49 to drive the worm gear 51 to rotate.

[0049] like Figure 12 , Figure 13 , Figure 15As shown, a spring 13 is sleeved at the end of the cloth roller 54. The inner end of the spring 13 is fixedly connected to the cloth roller 54, and the outer end is fixedly connected to the inner wall of the polymer plate 32. A friction roller 45 is rotatably provided in the groove of one side of the polymer plate 32. A motor 44 for driving the friction roller 45 to rotate is provided on the polymer plate 32.

[0050] Specifically, in the above embodiments, after multiple pipes are turned simultaneously, the electric chuck 29 releases the pipes, which fall into a container for collection. However, in some cases, personnel need to bundle the ends of the multiple turned pipes together for subsequent transport and storage. However, when multiple pipes fall into the container simultaneously, they will again be piled up haphazardly, requiring personnel to first organize and align them before bundling. This not only increases the intensity of manual labor but also, due to the low efficiency of manual organization and alignment, is difficult to match with the high efficiency of the aforementioned multi-station synchronous turning, thus restricting the continuity of the overall processing and subsequent procedures.

[0051] Therefore, to solve the above problems, a cylindrical structure is formed by multiple polymer plates 32 and multiple filler fabrics 33. After a set of pipe fittings is machined, the lead screw linear module 21 drives the fixed seat 23 to move laterally, that is, the cylindrical structure moves laterally, so that the cylindrical structure moves sequentially under each electric chuck 29. At the same time, the motor 25 drives the variable pitch slide 26 to rotate, so that the pipe fittings have their openings facing downwards. When a pipe fitting is aligned with the inner cavity of the cylindrical structure, the corresponding electric chuck 29 releases the pipe fitting, and the pipe fitting will fall into the cylindrical structure. The above operation is repeated until a specified number of pipe fittings have fallen into the cylindrical structure. The pipe fittings will then rest against the inner wall of the cylindrical structure.

[0052] Subsequently, the motor 39 drives the threaded rod 41 to rotate, causing the connecting ring 36 to rise. Multiple connecting rods 35 then drive multiple radial rods 34 to slide on multiple limiting rods 42, causing multiple polymer plates 32 to simultaneously approach the axis of the fixed disk 40. Simultaneously, the filling cloth 33 is wound up by the cloth roller 54 under the torque of the spring spring 13, continuously reducing the size of the cylindrical structure. At this point, multiple pipes inside the cylindrical structure are gradually gathered together by the polymer plates 32 and the wound filling cloth 33, causing the pipes originally leaning against the inner wall of the cylindrical structure to continuously converge towards the center of the cylinder. During the gathering process, the pipes automatically adjust their posture, ultimately arranging them neatly along the axial direction of the cylindrical structure and tightly adhering to each other, forming a bundle of pipes that is easy to bundle. Personnel can then directly bundle the ends of the bundle of pipes uniformly, eliminating the need for individual sorting and alignment of each pipe, reducing manual labor intensity. Furthermore, the sorting, alignment, and bundling processes can match the high efficiency of the aforementioned multi-station synchronous turning, improving overall processing efficiency.

[0053] Furthermore, during the folding process of the cylindrical structure, it is easy for the pipes to get stuck due to abutment between each other or between the pipes and the inner wall of the cylinder. This prevents the cylindrical structure from being folded to the specified size, leaving a certain amount of redundant space in the cylindrical structure. This affects the folding effect of multiple pipes, resulting in loose and misaligned pipe bundles. This is not conducive to subsequent unified binding and may even cause the pipes to shift during transportation due to insufficient adhesion between them, affecting the binding's firmness.

[0054] Therefore, during the gathering process, if a pipe gets stuck, motor 44 drives friction roller 45 to rotate, causing friction roller 45 to contact a pipe on either side of the cylinder structure. The friction force then causes the pipe to shift, breaking the jamming and allowing the pipe to continue gathering towards the center of the cylinder. This further improves the reliability and efficiency of pipe gathering, avoiding problems such as the cylinder structure failing to gather properly or the pipe bundle becoming loose or misaligned due to pipe jamming.

[0055] Furthermore, if the depth of the cylindrical structure is fixed, some problems will arise. When the length of the pipe is less than the depth of the cylindrical structure, the end of the pipe is below the opening of the cylindrical structure, making it difficult to bind properly. If the depth of the cylindrical structure is set too small to avoid this situation, the pipe, when located in the cylindrical structure, is prone to tilting or shifting due to instability or external forces such as vibration or collision, and may fall out of the opening of the cylindrical structure, causing the pipe to scatter and affecting the normal gathering and binding process. Therefore, to avoid this problem, the lifting plate 43 can be raised and lowered using cylinder 48 according to the length of the pipe. This adjusts the distance between the lifting plate 43 and the opening of the cylindrical structure to match the length of the pipe, so that after the pipe falls into the cylindrical structure, its end is located just near or extends out of the opening, making it convenient for personnel to bind the end of the pipe uniformly, while preventing the pipe from accidentally falling out due to extending too far out of the opening. Furthermore, when the dimensions of the cylindrical structure change, the fitting rod 49 will always be in contact with the surface of the polymer plate 32 under the action of the spring 46. In addition, the motor 52 drives the worm gear 51 to rotate, which in turn causes multiple take-up and undo wheels 53 to rotate simultaneously under the transmission of the worm gear 51 and the worm wheel 50, winding up and unwinding the wire rope 47. This ensures that the part of the wire rope 47 located outside the mounting shell 48 remains taut. The wire rope 47 fills the gap between the lifting plate 43 and the polymer plate 32 to support the pipe. Thus, during the process of closing or enlarging the cylindrical structure, the gap between the lifting plate 43 and the polymer plate 32 is always effectively sealed by the wire rope 47, preventing the end of the pipe from protruding from the gap. This ensures that the pipe can stand stably in the cylindrical structure and neatly gather together as the cylindrical structure closes, which facilitates subsequent unified bundling and transportation.
