Description

Technical Field

[0001] This utility model relates to the technical field of automated conveying equipment, specifically to an automatic loading and unloading tube cutting mechanism. Background Technology

[0002] In modern industrial production, heavy-duty pipes are widely used in energy, construction, and machinery manufacturing due to their high strength and toughness. However, the loading, unloading, and processing of heavy-duty pipes have become a bottleneck restricting efficient production in the industry. Currently, most pipe processing equipment on the market separates the loading and unloading functions from the pipe cutting functions, requiring manual transfer or additional intermediate steps. This not only increases the safety risks of handling heavy-duty pipes, but the frequent start-ups and shutdowns also significantly reduce overall production efficiency. Existing pipe loading and unloading mechanisms have revealed many drawbacks when dealing with heavy-duty pipes: on the one hand, their structural design is mostly based on conventional pipe specifications, and their load-bearing capacity and mechanical strength are insufficient for heavy-duty pipes. In practical applications, due to the weight and size requirements, equipment components often deform or are damaged due to overload operation, which seriously affects the overall stability and service life of the equipment. On the other hand, these mechanisms are extremely unsuitable for different lengths of heavy pipes. When it is necessary to connect heavy pipes of different lengths, it is often necessary to carry out large-scale and costly modifications to the overall mechanism. This process is time-consuming and labor-intensive, making it difficult to achieve flexible production and hindering the improvement of production efficiency. At the same time, traditional pipe cutting equipment and loading and unloading mechanisms lack coordinated design, making it impossible to complete the pipe cutting operation simultaneously during the pipe loading and unloading process. The material flow efficiency is low, which makes it difficult to meet the urgent needs of modern industry for efficient and continuous production.

[0003] It is evident that existing pipe processing methods and mechanisms are no longer sufficient to meet the urgent needs of modern industry for efficient, flexible, and integrated processing and loading / unloading of heavy-duty pipes. There is an urgent need to develop an integrated automatic loading / unloading and cutting mechanism for heavy-duty pipes to solve the current technical challenges in production.

Detailed Implementation

[0029] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0030] like Figure 1-11As shown, an automatic pipe cutting and unloading mechanism includes: a slide rail assembly 1, a pipe cutting assembly 11, a loading chuck assembly 3, a loading assembly 4, an unloading chuck assembly 5, a receiving rack 6, an auxiliary conveying assembly 7, and a first transmission assembly 9. The pipe cutting assembly 11 is mounted on the slide rail assembly 1. The pipe cutting assembly 11 has a loading area 21 and a receiving area 22 on both sides. When cutting long, large, or heavy pipes, i.e., when the pipe is in the cutting area of ​​the cutting assembly, with one end of the pipe still in the loading area 21 and the other end in the receiving area 22, the loading chuck assembly 3 and the unloading chuck assembly 5 cooperate to clamp both ends of the pipe, realizing the cutting and unloading of the pipe. Both sections of the cut material can be clamped, improving the safety and stability of the pipe cutting process; the feeding chuck assembly 3 is located in the feeding area 21, and is slidably connected to the slide rail assembly 1; the feeding assembly 4 is located in the feeding area 21, and the feeding chuck assembly 3 is located on the output end of the feeding assembly 4; the unloading chuck assembly 5 is located in the receiving area 22, and is slidably connected to the slide rail assembly 1; the feeding chuck assembly 3 and the unloading chuck assembly 5 are arranged coaxially; the receiving rack 6 is located at the output end of the receiving area 22, and at least one drive receiving assembly 61 is provided along its length at the receiving end of the receiving rack 6; auxiliary conveying assembly 7. The feeding rack 6 is mounted on the receiving rack 6 and located at the discharge end of the drive receiving assembly 61. The receiving rack 6 has at least one feeding assembly 62 along its length. The number of drive receiving assemblies 61 and the feeding area are rationally set according to the pipe length, which can cover the pipe feeding needs of more length specifications and reduce unnecessary configurations of drive receiving assemblies 61 and feeding areas, thereby reducing equipment procurement and installation costs. Through the flexible design of the number and spatial distribution of each component, it is possible to quickly accommodate heavy-duty pipes of different lengths without large-scale modifications to the overall heavy-duty pipe automatic receiving mechanism, significantly reducing modification costs and time costs. This improves production flexibility. The feeding component 62 is located beside the auxiliary feeding component 7. After cutting, or if the feeding component 62 in front of the corresponding receiving rack 6 has no free material placement position, the unloading chuck component 5 moves the feeding component 62 behind the receiving rack 6 to unload the material. The first transmission component 9 is set on the receiving rack 6 and is connected to both the auxiliary feeding component 7 and the feeding component 62. This connection method allows the first transmission component 9 to directly drive the movement of the auxiliary feeding component 7 and the feeding component 62 to transport the pipe. The first transmission component 9 is used to drive the auxiliary feeding component 7 and the feeding component 62 to transport the pipe.

[0031] In this embodiment, the loading chuck assembly 3 and the unloading chuck assembly 5 are coaxially arranged and slidably connected to the slide rail assembly 1. When cutting long, heavy pipes, they can dynamically clamp both ends of the pipe, effectively preventing the pipe from shaking or shifting during cutting, significantly improving cutting safety and stability, and reducing the risk of damage to equipment components due to uneven force. The flexible layout of the drive receiving assembly 61, auxiliary conveying assembly 7, and feeding assembly 62 on the receiving rack 6 allows for adjustment of their quantity and position according to the pipe length. This not only accurately covers the receiving and feeding needs of pipes of different specifications but also reduces redundant configurations. This mechanism significantly reduces equipment procurement, installation, and modification costs, enabling flexible production. The first transmission component 9 directly drives the auxiliary conveying component 7 and the feeding component 62, ensuring efficient and stable pipe transmission. Combined with the flexible unloading strategy of the unloading chuck component 5, it effectively avoids material blockage and improves material flow efficiency. This mechanism integrates unloading, loading, unloading, and pipe cutting functions, reducing manual handling and intermediate links, eliminating safety hazards during handling, and achieving continuous processes. It meets the urgent needs of modern industry for efficient, flexible, and integrated processing of heavy-duty pipes, promoting a comprehensive improvement in industry production efficiency and processing quality.

[0032] In another embodiment, such as Figure 1 As shown, an outer sheet metal panel is added to the automatic loading and unloading pipe cutting mechanism. This outer sheet metal panel isolates the machine from external dust, preventing interference with the operation of the guide rails, sliders, gears, and racks, thus maintaining a clean working condition inside the machine, extending its service life, and improving the overall aesthetics. The outer sheet metal panel also provides individual cable wrapping for protection and offers centralized installation locations for power and air supply components, facilitating observation and adjustment. Simultaneously, it enhances the overall safety of the mechanism, preventing personnel from approaching or entering the machine during operation. Both the loading assembly 4 and the unloading assembly are equipped with hydraulically supported flip-top doors on their outer sheet metal panels, facilitating inspection and maintenance. Inspection doors are located at both ends of the loading area 21 and the receiving area 22, allowing access to the machine during maintenance. Protective covers are added to areas in the loading area 21 and the receiving area 22 where clothing and other items could easily get caught, protecting both the equipment's operation and personnel safety.

[0033] The feeding assembly 4 includes multiple spaced-apart rack modules 41, which can accommodate the feeding of pipes of different lengths. It also includes a second transmission assembly 42 and a feeding frame 43, which is located on the feeding area 21. The second transmission assembly 42 is mounted on the feeding frame 43 and is connected to each rack module 41. By controlling the synchronous operation of each rack module 41 through the control center, it can support and transport long, heavy pipes. The control center can also control individual rack modules 41. During operation, it can support and transport long pipes. Through the cooperation of various material rack modules 41, feeding chuck assembly 3, slide rail assembly 1 and other components and modules, the feeding assembly 4 is suitable for square pipes, rectangular pipes, H-shaped pipes, rectangular steel, channel steel, angle iron, small diameter round pipes, medium diameter round pipes, large diameter round pipes and other profiles, with stronger versatility and adaptability. The material rack module 41, the second transmission assembly 42 and the feeding frame 43 are all set on the feeding frame 43, and the feeding chuck assembly 3 is located on the output end of the feeding assembly 4.

[0034] In this embodiment, multiple spaced rack modules 41 can flexibly adjust their support points according to the length of the pipe. Whether it is a short pipe or an ultra-long heavy pipe, one or more rack modules 41 can be controlled by the control center to operate in coordination, achieving stable support and efficient handling of the pipe. This effectively avoids the risk of pipe slippage due to insufficient support. The linkage design between the second transmission component 42 and the rack module 41 ensures reliable power transmission when the modules are running synchronously, providing continuous and stable conveying power for long pipes. At the same time, the feeding component 4, through its organic cooperation with the feeding chuck component 3, slide rail component 1, etc., can be compatible with various complex profiles such as square pipes, rectangular pipes, and H-shaped steel, as well as round pipes from small diameter to ultra-large diameter, greatly expanding the application scenarios of the equipment. This highly integrated and intelligent feeding solution not only reduces the equipment debugging cost caused by changing pipe specifications, but also significantly improves the versatility and production efficiency of the production line, providing an innovative solution for the intelligent upgrading of the heavy pipe processing industry.

[0035] The material rack module 41 includes a drive sprocket 44, a driven sprocket 45, a material rack frame 46, a feeding chain 47, a traversing slide plate 48, a traversing drive mechanism 49, a first lifting slide plate 10, a lifting drive mechanism 23, a material support assembly 24, a clamping and positioning mechanism 25, and a clamping drive mechanism 26. The material rack frame 46 is located in the feeding area 21, and the feeding chuck assembly 3 is located on the output end of the material rack frame 46. The drive sprocket 44 and the driven sprocket 45 are rotatably mounted on the material rack frame 46. The feeding chain 47 is wound around the drive sprocket 44 and the driven sprocket 45. A support base plate is provided in the inner ring of the feeding chain 47, and the support base plate is located on the material rack frame 46. The plate is equipped with a support plate to support the material-carrying section of the feeding chain 47. Multiple second limiting blocks 27 are distributed on the outer side of the feeding chain 47. These second limiting blocks 27 are detachably connected to the feeding chain 47, and a storage station is formed between two adjacent second limiting blocks 27. Each storage station, or any storage station, holds a pipe to be processed. When the feeding chuck assembly 3 retrieves material, it must first remove the pipe from the storage station located on the output section of the material rack frame 46. The transverse sliding plate 48 is slidably connected to the material rack frame 46, and the transverse drive mechanism 49 is mounted on the material rack frame 46. The transverse drive mechanism 49 is drively connected to the transverse sliding plate 48. The first lifting slide plate 10 is mounted on the transverse slide plate 48 and is slidably connected to the transverse slide plate 48. The lifting drive mechanism 23 is mounted on the transverse slide plate 48 and is drively connected to the first lifting slide plate 10. The material support assembly 24 is located on top of the first lifting slide plate 10 and is used to receive and support the pipes on the storage station. The material support assembly 24 is the output section of the material rack frame 46. Under the action of the transverse drive assembly, the transverse slide plate 48 is driven to move towards the material rack frame 46. After reaching the position, the material support assembly 24 moves to below any storage station on the feeding chain 47 (prioritizing the pipes in front). The lateral drive assembly stops operating, and then, under the action of the lifting drive mechanism 23, the first lifting slide plate 10 is driven to rise. The material support assembly 24 supports the bottom of the pipe from bottom to top, so that the pipe is located above the storage station. When feeding, under the action of the lateral drive assembly, the lateral slide plate 48 is driven to move towards the slide rail assembly 1. The clamping positioning mechanism 25 and the clamping drive mechanism 26 are both set on the first lifting slide plate 10. The clamping positioning mechanism 25 is located next to the material support assembly 24. The clamping drive mechanism 26 is connected to the clamping positioning mechanism 25. The clamping positioning mechanism 25 is used to clamp the pipe on the material support assembly 24 to the set position.

[0036] In this embodiment, the driving sprocket 44 and driven sprocket 45, in conjunction with the detachable second limiting block 27, enable orderly storage of pipes while flexibly adjusting the spacing between storage stations to accommodate the transportation of pipes of different specifications. The logic of prioritizing the retrieval of output pipes ensures the continuity of the feeding process and avoids wasted idle time. The dual-drive structure of the transverse sliding plate 48 and the first lifting sliding plate 10, through the cooperation of the transverse drive mechanism 49 and the lifting drive mechanism 23, drives the supporting component 24 to below the designated storage station, smoothly lifting the pipes in a transverse-then-lifting manner, effectively preventing collisions or slippage during transfer and ensuring safety. Material feeding safety: Through the linkage design of clamping positioning mechanism 25 and clamping drive mechanism 26, the pipe can be quickly clamped and calibrated to the set position after being lifted into place, so that the pipe is centered and clamped, avoiding pipe deviation and providing a benchmark for subsequent processing. The whole solution, through the organic cooperation of modular components, not only realizes the full-process automation of pipe from storage and picking to positioning, but also improves the adaptability to heavy pipes of different shapes and sizes with its flexible structural adjustment capability, effectively reducing manual intervention and equipment debugging costs, significantly improving the operating efficiency and stability of the production line, and injecting new momentum into the intelligent upgrading of the heavy pipe processing industry.

The pipe cutting assembly 11 includes a gantry frame 111 and a laser generator. The gantry frame 111 is located on the slide rail assembly 1, and the laser generator is mounted on the gantry frame 111.

The first loading chuck 31 and the second loading chuck 32 slide to a suitable position and together clamp the tube to be cut from the output end of the material rack frame 46 into the processing range of the laser generator until the tube to be processed is concentric with the first unloading chuck 51 and the second unloading chuck 52. After the first unloading chuck 51 and the second unloading chuck 52 together clamp the other end of the tube, the laser generator cuts the tube portion located between the loading chuck assembly 3 and the unloading chuck assembly 5, and the first unloading chuck 51 and the second unloading chuck 52 together clamp the tube portion cut by the laser generator.

[0039] In this embodiment, the first loading chuck 31, the second loading chuck 32, and the first unloading chuck 51 and the second unloading chuck 52 are all slidably connected to the slide rail assembly 1 and arranged coaxially, enabling them to flexibly clamp the pipe. During the handling and cutting of the pipe, this design effectively avoids the pipe's swaying and offset, ensuring the accuracy and stability of the cutting. The pipe cutting assembly 11, using a gantry frame 111 equipped with a laser generator, is positioned between the loading area 21 and the receiving area 22, further ensuring the accuracy of the cutting position. During operation, the loading chuck assembly 31... The output end of the material rack 46 clamps the pipe and moves it to the laser generator processing area. After aligning with the unloading chuck assembly 5, the unloading chuck assembly 5 clamps the other end of the pipe. Subsequently, the laser generator cuts the pipe into two parts, and the unloading chuck assembly 5 clamps the pipe part cut by the laser generator and unloads it. The entire process achieves efficient connection between pipe picking and cutting, improves production efficiency, reduces the risk of pipe deformation or displacement, and ensures cutting quality and safety. At the same time, the coaxially arranged chuck assembly enhances the adaptability to pipes of different lengths and improves the versatility of the equipment.

[0040] The automatic loading and unloading pipe cutting mechanism also includes a sensing component 8, which is located at the discharge end of the auxiliary conveying component 7 and electrically connected to the first transmission component 9. The sensing component 8 detects the material level information on the auxiliary conveying component 7 and controls the start / stop state of the first transmission component 9 based on this information. This location allows the sensing component 8 to detect the material level when the pipe is conveyed to the discharge end of the auxiliary conveying component 7, thus obtaining the material level information in a timely manner. All sensing components 8 adopt a modular design, allowing for easy disassembly, replacement, or upgrading. For example, when adapting to new pipe materials, only the corresponding limiting block needs to be replaced or the sensor type of the sensing component 8 needs to be upgraded. No changes to the entire equipment structure are required; the auxiliary material conveying assembly 7 includes a first frame 72, two first bearings 73, two first tensioning modules 74, a first rotating shaft 75, a second rotating shaft 76, a first universal joint coupling 77, a first sprocket 78, a second sprocket 79, a third sprocket 80, a fourth sprocket 83, a first conveying chain 84, a second conveying chain 85, and a chain plate module 86; the first transmission assembly 9 includes a transmission shaft 91 and a drive source 92. The first frame 72 is mounted on the receiving rack 6 and is located beside the material conveying area. The two ends of the first rotating shaft 75 are connected to the first frame 72 through two first bearings 73, and the first rotating shaft 75 is located on one side of the first frame 72. The first sprocket 78 and the third sprocket 80 are respectively sleeved on both ends of the first rotating shaft 75; the drive shaft 91 is mounted on the receiving frame 6; one end of the first rotating shaft 75 is connected to the drive shaft 91 via the first universal joint coupling 77, and the sensing component 8 is located at the starting end of the extension of the first frame 72, which can adapt to the detection requirements of short to long pipes. The sensing component 8 can detect the material level information of pipes of different lengths in real time and transmit the material level information to the drive source 92, thereby realizing the adjustment of the start and stop state of the drive source 92 by the sensor 82; the power is transmitted from the drive source 92 to the first rotating shaft 75 via the drive shaft 91 and the first universal joint coupling 77; the universal joint coupling can compensate for the transmission The misalignment caused by a certain angular deviation or displacement between the axis of shaft 91 and the first rotating shaft 75 is addressed to ensure that the drive shaft 91 and the first rotating shaft 75 can maintain mutual connection and transmit torque, reducing the strict requirements for axis matching; the drive source 92 is located on the receiving rack 6; the drive source 92 is driven by the drive shaft 91; the drive source 92 is electrically connected to the sensing component 8; both ends of the second rotating shaft 76 are connected to the first frame 72 through two first tensioning modules 74, and the second rotating shaft 76 is located at the other end of the first frame 72; the second sprocket 79 and the fourth sprocket 83 are respectively sleeved on both ends of the second rotating shaft 76; the first conveying chain 84 is wound around the first sprocket 78 and the second sprocket 79;The second conveyor chain 85 is wound around the third sprocket 80 and the fourth sprocket 83. The drive source 92 synchronously drives the transmission shaft 91 to rotate, which in turn drives the first rotating shaft 75 and the first sprocket 78 and the third sprocket 80 on the first rotating shaft 75 to rotate, providing power to the first conveyor chain 84 and the second conveyor chain 85, and driving the pipe forward. In order to adjust the tension of the conveyor chain, the front and rear positions of the second rotating shaft 76 can be finely adjusted by adjusting the two first tensioning modules 74, so that the conveyor chain can obtain a suitable tension. In order to prevent the conveyor chain from continuing to drive the pipe forward after the pipe is transported to the output end of the conveyor assembly due to control failure, which would cause the pipe to fall off the conveyor chain and be damaged, the side of the first frame 72 is provided with a baffle plate to block the pipe from continuing to be conveyed forward. The chain plate module 86 is located between the first conveyor chain 84 and the second conveyor chain 85, and the feed end of the chain plate module 86 is located at the drive receiving assembly 61. The feeding end of the chain plate module 86 is directly connected to the feeding end of the drive receiving component 61, so that the pipe is directly received by the chain plate module 86 at the feeding end of the drive receiving component 61, forming a compact integrated receiving structure. At the same time, the close cooperation between the two enhances the synergy of the entire receiving mechanism. The chain plate module 86 adopts a detachable structure, such as being connected to the double chain by bolts, buckles, etc. The chain plate module 86 serves as a continuous support surface, distributing the weight of the heavy pipe evenly on the double chain, avoiding chain deformation or breakage caused by single-point force. The sensing component 8 is mounted on the first frame 72 and located at the feeding end of the chain plate module 86. The auxiliary conveying component 7 is provided with multiple first limiting blocks 71, forming multiple first storage slots 711 on the auxiliary conveying component 7. The multiple first limiting blocks 71 are distributed on the outer surfaces of the first conveying chain 84 and the second conveying chain 85, and the first storage slots 711 are located between two adjacent first limiting blocks 71.

[0041] In this embodiment, the sensing component 8 monitors the position of pipe materials of different lengths in real time, and intelligently controls the start and stop of the drive source 92 in conjunction with the drive component 92 to meet the detection requirements of pipe materials of different lengths and improve the applicability of the equipment. In the transmission component, the universal joint coupling effectively compensates for the angular and displacement deviations between the drive shaft 91 and the first rotating shaft 75, reduces the requirements for shaft matching, and ensures stable power transmission. The drive source 92 drives the sprocket and the conveyor chain through the drive shaft 91 and the first rotating shaft 75 to provide reliable power for pipe material conveying. At the same time, the first tensioning module 74 can flexibly adjust the tension of the conveyor chain to ensure that the chain is in the best working state and extend its service life. The chain plate module 86 is connected to the drive receiving component 61 to realize... The efficient connection of pipes enhances equipment synergy; the detachable design of the 86 chain plate module facilitates maintenance and replacement, and evenly distributes the weight of the pipes, avoiding excessive local stress on the chain, improving chain reliability and equipment stability, effectively reducing the risk of failure, and increasing conveying efficiency. It provides stable and efficient operation for pipe inspection and conveying, and is suitable for various pipe processing and production scenarios. The overall solution, through modular and adjustable structural design, enables the equipment to quickly adapt to multiple specifications of pipes, reducing procurement, modification, and maintenance costs. At the same time, intelligent control optimizes the production process, providing an efficient, economical, and safe material receiving solution for heavy pipe processing.

[0042] The sensing component 8 includes a sensing plate 81, a sensor 82, and a reset component. The sensing plate 81 is rotatably connected to the first frame 72 via the reset component, which is used to reset the sensing plate 81. The sensor 82 is mounted on the first frame 72 and is located below the sensing plate 81. The sensing plate 81 flips under the force of the pipe or the force of the reset component. The sensor 82 is used to detect the flipping signal of the sensing plate 81 and to start and stop the drive source 92 according to the flipping signal. Common types of reset components include spring reset mechanisms and torsion spring reset mechanisms. The sensor 82 includes a limit switch. When the pipe slides into the center of the sensing plate 81, the weight of the pipe causes the sensing plate 81 to flip, thereby triggering the limit switch. The limit switch feeds back the flipping signal to the control system in the sensor 82. The control system controls the rotation drive source 92 to stop working, so that the pipe is just moved to the discharge end of the auxiliary conveying component 7. When the sensing plate 81 is flipped by force, the torsion spring deforms and stores energy. After the external force disappears, the torsion spring releases energy to reset the sensing plate 81.

[0043] In this embodiment, intelligent control of pipe conveying is achieved through the coordinated operation of the sensing plate 81, sensor 82, and reset assembly. When the pipe slides into the center of the sensing plate 81, its own weight causes the sensing plate 81 to flip, triggering the limit switch. After receiving the signal, the control system controls the drive source 92 to stop working, ensuring that the pipe can be precisely moved to the discharge end of the auxiliary conveying assembly 7, avoiding the problem of over- or under-conveying of the pipe and improving the conveying accuracy. The reset assembly adopts a common spring reset mechanism or torsion spring reset mechanism, which enables the sensing plate 81 to quickly reset after the pipe leaves, preparing for the next sensing and ensuring the continuity and stability of sensing. In addition, the detection is triggered by the weight of the pipe itself, simplifying the signal acquisition process and reducing the complexity of the equipment structure. This optimizes production efficiency and achieves efficient, accurate, and stable automated control in the pipe conveying scenario, providing strong support for the smooth operation of the production process.

[0044] The drive receiving assembly 61 includes a second frame 63, a lifting drive motor 64, a second lifting slide plate 65, a third lifting slide plate 66, a driving chain 67, a third rotating shaft 68, a receiving platform 69, and a tilting drive mechanism 70. The second lifting slide plate 65 is connected to a first slider, and the second frame 63 is connected to a first vertical guide rail. The first slider is slidably connected to the first vertical guide rail. The lifting drive motor 64 is mounted on the second lifting slide plate 65, and a gear is provided on the output end of the lifting drive motor 64. The gear meshes with a rack, which is fixed to the second frame 63. The lifting drive motor 64 drives the second lifting slide plate 65 to move up and down along the length of the rack. A first positioning block is provided at the bottom of the third lifting slide plate 66, and a second positioning block is provided on one side of the top of the second frame 63. The first positioning block is connected to the second positioning block via a moving chain 67. A third rotating shaft 68 is rotatably mounted on the upper part of the second lifting slide plate 65. A moving sprocket is sleeved on the third rotating shaft 68 and meshes with the moving chain 67. A second slider is connected to the side of the second lifting slide plate 65 away from the first slider. A second vertical guide rail is connected to the third lifting slide plate 66, and the second slider is slidably connected to the second vertical guide rail. The second lifting slide plate 65 drives the third lifting slide plate 66 to rise and fall via the moving chain 67. A receiving platform 69 is hinged to the upper part of the third lifting slide plate 66. A tilting drive mechanism 70 is mounted on the third lifting slide plate 66 and drives the receiving platform 69 to swing along the hinge point between the receiving platform 69 and the upper part of the third lifting slide plate 66.

[0045] In this embodiment, the lifting structure design utilizes the sliding connection between the second lifting slide plate 65 and the first vertical guide rail, along with the cooperation of the lifting drive motor 64, gears, and racks, to achieve the lifting of the second lifting slide plate 65 along the length of the rack. This design is not only compact but also provides stable and reliable lifting action. It allows for flexible adjustment of the height of the receiving platform 69 to meet the pipe receiving requirements. Furthermore, the linkage of the moving chain 67, moving sprocket, and the third lifting slide plate 66 enables the lifting of the second lifting slide plate 65 to drive the third lifting slide plate 66 to lift synchronously, further enhancing the coordination and stability of the entire lifting system. The receiving platform 69 supports the pipe and is driven by the flipping drive mechanism 70 to swing and flip along the hinge point, causing the pipe to tilt and fall onto the auxiliary conveying assembly. This tilting method effectively reduces the impact force when the pipe falls, lowering the risk of pipe damage, and also improves the smoothness and efficiency of pipe conveying.

[0046] The flipping drive mechanism 70 includes a drive cylinder, a receiving platform 69, a first hinge seat 28 and a second hinge seat 29. The bottom of the drive cylinder is hinged to the third lifting slide plate 66 through the first hinge seat 28, and the output end of the drive cylinder is fixedly hinged to the bottom of the receiving platform 69 through the second hinge seat 29.

[0047] In this embodiment, by controlling the extension and retraction of the cylinder, the swing angle of the receiving platform 69 can be adjusted to adapt to the unloading requirements of pipes of different specifications, ensuring that the pipes can fall smoothly and stably from the receiving platform 69 onto the auxiliary conveying assembly, reducing the possibility of pipe damage and improving conveying efficiency and quality. The arrangement of the first hinge seat 28 and the second hinge seat 29 forms a flexible hinge connection between the drive cylinder, the third lifting slide plate 66, and the receiving platform 69, ensuring the smoothness and stability of the receiving platform 69 during the swing process. This hinge structure can effectively buffer the impact force generated when the cylinder moves, reduce the wear and failure probability of the equipment, and extend the service life of the equipment.

[0048] The drive receiving assembly 61 also includes a material conveying roller 30 and two bearing seats 33. The receiving platform 69 has a strip-shaped through groove. The two bearing seats 33 are symmetrically fixed at both ends of the strip-shaped through groove. The two ends of the material conveying roller 30 are rotatably connected to the two bearing seats 33 respectively. The material conveying roller 30 extends along the conveying pipe direction, and its upper side protrudes out of the strip-shaped through groove.

[0049] In this embodiment, since the surface of the roller is chrome-plated, it is smooth and has high hardness, which facilitates the rolling of the pipe. The friction between the pipe and the roller is small and will not damage the pipe.

[0050] In this embodiment, the conveying roller 30 has a smooth surface and protrudes from the strip groove of the receiving platform 69. This reduces friction loss when the pipe rolls on the roller, effectively protecting the pipe surface from scratches or wear, and is especially suitable for high-precision or easily damaged pipes. Secondly, two bearing seats 33 are symmetrically fixed at both ends of the strip groove, ensuring that the axis of the conveying roller 30 is aligned with the pipe conveying direction. The two ends of the roller are connected by bearings, which reduces the rolling resistance of the pipe and makes the conveying process smoother. The design of the strip groove not only provides a precise installation reference for the bearing seats 33, but also facilitates the disassembly and maintenance of the roller. When a single roller is damaged, it can be quickly replaced, improving maintenance efficiency. In addition, the layout of the conveying roller 30 extending along the pipe conveying direction can adapt to pipes of different lengths, enhancing the versatility of the equipment. Overall, this design significantly improves the receiving efficiency and pipe quality by reducing friction loss, improving conveying smoothness and convenient maintenance, providing efficient and reliable technical support for the automated receiving of heavy-duty pipes.

[0051] The feeding assembly 62 includes a third frame 34, a second bearing 35, a second tensioning module 37, a fourth shaft 36, a fifth shaft, a second universal joint coupling, a fifth sprocket, a sixth sprocket, a third conveyor chain, and multiple third limiting blocks 38. The third frame 34 is mounted on the receiving frame 6 and is located beside the first frame 72. One end of the fourth shaft 36 is connected to the third frame 34 via the second bearing 35, and the other end of the fourth shaft 36 is connected to the drive shaft 91 via the second universal joint coupling. The transmission connection includes a fourth rotating shaft 36 located at one end of the third frame 34; a fifth sprocket mounted on the fourth rotating shaft 36; the two ends of the fifth rotating shaft are connected to the third frame 34 via two second tensioning modules 37, and the fifth rotating shaft is located at the other end of the third frame 34; a sixth sprocket mounted on the fifth rotating shaft; a third conveyor chain wound around the fifth and sixth sprockets; and multiple third limiting blocks 38 distributed on the outer surface of the third conveyor chain, with a second storage slot formed between two adjacent third limiting blocks 38.

[0052] In this embodiment, from the perspective of structural connection and power transmission, the third frame 34 is set on the receiving frame 6 and located next to the first frame 72, which reasonably arranges the position of the feeding assembly 62. The fourth rotating shaft 36 is connected to the third frame 34 through the second bearing 35, and the other end is connected to the drive shaft 91 through the second universal joint coupling. This connection method not only ensures the stable support of the rotating shaft, but also effectively compensates for possible angular deviations or displacements between the drive shaft 91 and the fourth rotating shaft 36, so that power can be stably and efficiently transmitted from the drive shaft 91 to the fourth rotating shaft 36, thereby driving the entire feeding assembly 62 to run. The two tensioning modules can flexibly adjust the position of the fifth rotating shaft, thereby adjusting the tension of the third conveyor chain to ensure that the chain is always in a stable position. A suitable tension ensures the stability and reliability of the chain drive, extends the chain's service life, and improves the smoothness of the feeding process. Multiple third limiting blocks 38 are distributed on the outer side of the third conveyor chain, forming a second storage bay between adjacent limiting blocks. This design can position and restrict the pipes, effectively preventing them from shifting or slipping during transport, ensuring orderly and stable transport. Simultaneously, the second storage bay can also store pipes to a certain extent, buffering the transport rhythm and adapting to different production needs and work rhythms, thus improving the flexibility and adaptability of the entire conveying system. The feeding assembly 62 has a simple overall structure, is easy to install, maintain, and repair, and provides stable and reliable support for the transport of heavy-duty pipes.
