Description

Technical Field

[0001] This application relates to the field of welding equipment for ship hull longitudinal skeletons, and in particular to a welding equipment for intelligent assembly of ship hull longitudinal skeletons. Background Technology

[0002] During the manufacturing and assembly of the ship's hull, gantry-type longitudinal girder welding equipment is required to assemble and weld the longitudinal girders of the hull to the steel plates. The existing gantry-type longitudinal rib welding equipment includes a movable frame, which is set on a horizontally extending ground rail. The movable frame moves laterally on the ground rail by rotating the traveling wheels driven by a motor. At the bottom of the movable frame, an electromagnet assembly and a welding assembly are raised and lowered via a telescopic component. The welding assembly can move vertically and laterally relative to the longitudinal moving assembly, while the electromagnet assembly can rise and fall vertically. In use, after the movable frame moves laterally to the material picking station, the electromagnet assembly descends and, in coordination with the position adjustment of the movable frame, moves to the side of the longitudinal rib to pick up and fix the longitudinal rib. Then, the electromagnet assembly resets and drives the longitudinal rib to rise. The movable frame moves to the welding position, aligning the longitudinal rib with the marking line of the steel plate. The electromagnet assembly drives the longitudinal rib to descend, and then, through an electric push rod, it abuts the top of the longitudinal rib so that the bottom surface of the longitudinal rib is in contact with the steel plate. Then, the welding assemblies located on both sides of the longitudinal rib adjust the distance between the welding torch and the longitudinal rib to weld the longitudinal rib and the steel plate. At the same time, the longitudinal drive mechanism drives the welding torch to move longitudinally along the longitudinal rib, coordinating with the movement and positioning of individual electromagnets in corresponding positions to complete the assembly and welding between the longitudinal rib and the steel plate.

[0003] However, in the traditional gantry welding equipment, the electromagnet components used to grab and assemble the longitudinal bones and the welding components used to weld the longitudinal bones and steel plates are set on the same moving frame. The next round of material picking can only be carried out after the welding of a single longitudinal bone and steel plate is completed, which leads to a decrease in the overall assembly and welding efficiency and makes it difficult to adapt to the working conditions of short construction period and large amount of longitudinal bone and steel plate welding. Summary of the Invention

[0004] This application proposes a welding equipment for intelligent assembly of longitudinal girders of ship hulls, which has the advantages of assembling and welding longitudinal girders and steel plates simultaneously and welding multiple longitudinal girders at the same time. This solves the problem that traditional gantry-type longitudinal girder welding equipment can only complete the assembly and welding of a single longitudinal girder in a linear process, resulting in a decrease in overall processing efficiency.

[0005] To achieve the above objectives, this application adopts the following technical solution: a welding equipment for intelligent assembly of ship hull longitudinal skeletons, comprising an assembly transverse moving frame, a welding transverse moving frame, a support frame, and several welding components. Several electromagnet components are fixedly arranged at the bottom of the support frame. A connecting plate is arranged inside the assembly transverse moving frame.

Several assembly vertical moving seats are slidably sleeved on the bottom of the support frame. A connecting frame is movably provided on the bottom of the support frame. The connecting frame is fixedly connected to the corresponding assembly vertical moving seat, and the connecting frame is slidably connected to the connecting plate.

[0008] Furthermore, a connecting seat is fixedly connected to the bottom of the longitudinal moving frame, and several transverse moving seats are slidably connected to the connecting seat. A welding vertical moving seat is slidably arranged on one side of the transverse moving seat, and the welding vertical moving seat is slidably connected to the corresponding welding component.

[0009] Furthermore, an adjustment frame is fixedly connected to the bottom midpoint of the assembly transverse moving frame, a mounting frame is fixedly connected to the bottom of the adjustment frame, and several No. 1 electric push rods are fixedly connected to the bottom of the mounting frame.

[0010] Furthermore, several transmission sprockets are rotatably arranged on both sides of the mounting frame, and a chain is driven between two corresponding transmission sprockets. The two corresponding transmission sprockets at both ends of the longitudinal bone are coaxially connected by a rotating shaft. A movable plate is movably arranged at the bottom of the first electric push rod, and the movable plate is drivenly connected to the output end of the first electric push rod. Chain plates are arranged on both sides of the movable plate.

[0011] Furthermore, fixed plates are provided on both sides of the movable plate, and the number of fixed plates is set to several. The fixed plates are fixedly connected to the corresponding chain plates. Support blocks are also provided, and the number of support blocks is set to several. The support blocks are slidably connected to the corresponding chain plates. One side of the bottom of the support block is arc-shaped. A movable plate is provided on one side of the fixed plate. The movable plate is fixedly connected to the corresponding support block. A number of No. 1 springs are provided on one side of the movable plate.

[0012] Furthermore, racks are fixedly connected to both the front and rear sides of the movable plate, and several of the top drive sprockets are connected to drive gears. The drive gears mesh with the corresponding racks. The vertical spacing of the support blocks corresponding to the chain plates at different heights is adapted to the height of the longitudinal bone itself, and the support blocks corresponding to the chain plates at the same height are at the same height.

[0013] Furthermore, a tensioning mechanism is provided on one side of the chain, and a second electric push rod is provided on one side of the chain. The output end of the second electric push rod is connected to an adjusting seat. Adjusting sprockets are rotatably provided on the top and bottom of the adjusting seat, and the adjusting sprockets are connected to the corresponding chain drive.

[0014] Furthermore, the tensioning mechanism includes a tensioning seat, a tensioning sprocket is rotatably mounted on one side of the tensioning seat, the tensioning sprocket is connected to the corresponding chain drive, and limit rods are slidably sleeved on both sides of the tensioning seat.

An adjusting rod is slidably engaged at one end of the inclined surface of the sliding rod. The adjusting rod is slidably sleeved with the connecting block. An adjusting plate is fixedly connected to one end of the adjusting rod.

[0016] The beneficial effects of this invention are as follows:

[0017] This application provides a welding device for intelligent assembly of ship hull longitudinal ribs. By horizontally adjusting the position of several welding components through a connecting plate, the device simultaneously welds individual longitudinal ribs while the electromagnet component grips the longitudinal rib to the welding position, improving the efficiency of initial welding and fixing. In conjunction with the welding transverse moving frame, after the initial welding and fixing of the longitudinal ribs, the longitudinal moving frame drives the corresponding welding components to simultaneously weld the joints between multiple longitudinal ribs and steel plates after adjusting the adjacent spacing. This completes the intelligent welding of ship hull longitudinal ribs, and the initial welding and subsequent full welding are performed separately, improving the overall welding efficiency.

[0018] This application provides a welding device for intelligent assembly of ship hull longitudinal girders. A guide plane is formed between adjacent chain plates, and a temporary support space is formed between opposing chain plates. After the electromagnet assembly drives the longitudinal girders to rise a rated distance, the fixing is removed, allowing the longitudinal girders to pass through a support block that retracts. The support block then springs back out, forming multi-point support. Combined with the transmission of a first electric push rod, the support block and longitudinal girders descend synchronously. This applies pressure to the bottom longitudinal girders, improving the flatness of the weld. Simultaneously, the support block is moved away from the bottom of the longitudinal girders by the chain plates, removing the support. This allows the device to complete the material handling of multiple longitudinal girders at once, further improving overall welding efficiency. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1, as Figures 1-7 A welding device for intelligent assembly of ship hull longitudinal skeletons includes an assembly transverse moving frame 1 and a welding transverse moving frame 10. Both the assembly transverse moving frame 1 and the welding transverse moving frame 10 are mounted on ground rails. A drive assembly drives the assembly transverse moving frame 1 and the welding transverse moving frame 10 to move along the transversely arranged ground rails. (See reference...) Figure 4 Sliding seats 2 are slidably provided on both sides of the assembly horizontal moving frame 1. The sliding seats 2 can slide vertically relative to the assembly horizontal moving frame 1. The sliding seats 2 are driven to move by the corresponding driving mechanism. A lifting plate 3 is provided on one side of the sliding seat 2. A movable frame 4 is provided between the two lifting plates 3. A support frame 5 is slidably connected to the outside of the movable frame 4. The support frame 5 is driven to move by the telescopic mechanism fixedly installed on the lifting plate 3.

[0033] The support frame 5 can move longitudinally relative to the movable frame 4, see reference. Figure 5The bottom of the support frame 5 is slidably fitted with several vertically movable mounting seats 6. The bottom of the support frame 5 is movably provided with connecting frames 7, and the number of connecting frames 7 is at least two. The connecting frames 7 are fixedly connected to the corresponding vertically movable mounting seats 6. The vertically movable mounting seats 6 are arranged in a rectangular shape with uniform intervals. The vertically movable mounting seats 6 are used to guide the vertical movement of the connecting frames 7. The connecting frames 7 are driven to rise and fall by telescopic components installed on the support frame 5. The bottom of the support frame 5 is fixedly provided with several electromagnet assemblies 8, which are arranged in a straight line with uniform intervals.

[0034] The electromagnet assembly 8 is used to attract and fix the longitudinal rib 21, and also includes several welding assemblies 9. A connecting plate 41 is slidably disposed at the bottom of the connecting frame 7. The connecting plate 41 is moved by a telescopic mechanism installed on the connecting frame 7. The connecting plate 41 is used to drive the welding assemblies 9 to slide longitudinally to perform preliminary welding of the butt joint. Several welding gun supports 42 are fixedly connected to the bottom of the connecting plate 41. (See reference...) Figure 6 The welding torch holder 42 is slidably connected to the corresponding welding assembly 9. The welding assembly 9 can slide relative to the connecting frame 7 in the vertical and horizontal directions to adjust the distance between the welding torch in the welding assembly 9 and the joint between the longitudinal rib 21 and the steel plate.

[0035] A longitudinal moving frame 11 is slidably mounted on the top of the welding transverse moving frame 10, see reference. Figure 2 The longitudinal moving frame 11 is used to move the welding assembly 9 along the longitudinal joint formed by the longitudinal rib 21 and the steel plate. The longitudinal moving frame 11 is driven by a drive device and can slide relative to the welding transverse moving frame 10. A connecting seat 12 is fixedly connected to the bottom of the longitudinal moving frame 11. (See reference) Figure 3 The connecting seat 12 is slidably connected to several transverse moving seats 13. The transverse moving seats 13 can move in the transverse direction relative to the connecting seat 12 to adjust the transverse spacing between several welding components 9 to adapt to different spacings of adjacent longitudinal ribs 21. The horizontal position of the several transverse moving seats 13 is adjusted by corresponding driving devices. A welding vertical moving seat 14 is slidably provided on one side of the transverse moving seat 13. The welding vertical moving seat 14 can slide vertically relative to the transverse moving seat 13 by corresponding driving devices to adjust the height of the welding components 9. The welding vertical moving seat 14 is slidably connected to the corresponding welding components 9. The welding components 9 can slide in the horizontal and vertical directions relative to the welding vertical moving seat 14 by corresponding driving devices to adjust the distance between the welding components 9 and the joint of the steel plate and longitudinal ribs 21.

[0036] An adjusting bracket 15 is fixedly connected at the bottom midpoint of the lateral moving frame 1. (See reference) Figure 7The bottom of the adjustment frame 15 is fixedly connected to the mounting frame 16, and the bottom of the mounting frame 16 is fixedly connected to several No. 1 electric push rods 17. The No. 1 electric push rods 17 are used to apply pressure close to the steel plate to the top of the longitudinal bone 21. The several No. 1 electric push rods 17 are arranged in a straight line with uniform intervals.

[0037] The working principle of this embodiment is as follows:

[0038] The assembly transverse moving frame 1 moves laterally along the ground rail to the material picking station. The assembly transverse moving frame 1 drives the sliding seat 2 to move, the sliding seat 2 drives the lifting plate 3 to move horizontally, which in turn drives the movable frame 4 to move. The movable frame 4 drives the support frame 5 to move, and the support frame 5 drives the electromagnet assembly 8 to move horizontally, so that the horizontal position of the electromagnet assembly 8 is located to the side of the longitudinal bone 21 to be assembled, so as to avoid interference between the electromagnet assembly 8 and the bottom of the T-shaped longitudinal bone 21 during the subsequent descent. Then, the sliding seat 2 moves down, and the transmission drives the support frame 5 to descend, so that the height of the electromagnet assembly 8 matches the height of the side wall of the longitudinal bone 21. The assembly transverse moving frame 1 moves laterally, so that the magnetic surface of the electromagnet assembly 8 is in contact with the side wall of the longitudinal bone 21. Several electromagnet assemblies 8 are activated and work together to attract and fix the longitudinal bone 21, completing the gripping of the longitudinal bone 21.

[0039] Next, as the sliding seat 2 rises, the transmission drives the electromagnet assembly 8 to move, causing the electromagnet assembly 8 to move the longitudinal rib 21 synchronously. The assembly transverse moving frame 1 moves to the assembly and welding position corresponding to the longitudinal rib 21, i.e., the marked position on the steel plate. The drive support frame 5 moves longitudinally relative to the movable frame 4, adjusting the horizontal position of both ends of the longitudinal rib 21 so that the horizontal position of the longitudinal rib corresponds to the marked position on the steel plate. The sliding seat 2 descends, causing the electromagnet assembly 8 to drive the bottom of the longitudinal rib 21 to contact the top surface of the steel plate. The first electric push rod 17 then applies pressure to the longitudinal rib 21, causing the longitudinal rib 21 to slide relative to the electromagnet assembly 8, so that the bottom surface of the longitudinal rib 21 fits against the top surface of the steel plate, completing the splicing of the steel plate and the longitudinal rib 21, and ensuring that the joint width between the steel plate and the longitudinal rib 21 is within the rated range, so as to improve the quality of subsequent welding.

[0040] Next, the drive connecting frame 7 descends relative to the movable frame 4, causing the height of the welding assembly 9 to drop to the rated value. Then, the corresponding welding assembly 9 is driven to tilt and move, causing the welding gun on the welding assembly 9 to move horizontally and vertically closer to the joint between the longitudinal bone 21 and the steel plate. At this time, the welding assemblies 9 are located on both sides of the side wall of the longitudinal bone 21. The welding assembly 9 is started, and the connecting plate 41 is driven to move longitudinally, causing the welding assembly 9 to move horizontally a rated distance relative to the welding joint. The welding assemblies 9 work together in pairs to weld the joints on both sides of the longitudinal bone 21 simultaneously, completing the initial welding and fixing between the longitudinal bone 21 and the steel plate.

[0041] The drive welding assembly 9 is reset and the electromagnet assembly 8 is closed. Then, the drive connecting frame 7 is raised and reset, and the sliding seat 2 is raised and reset. The drive connecting plate 41 and support frame 5 are moved horizontally and reset. The assembly transverse moving frame 1 is moved horizontally to the loading station for the next round of feeding. After the multiple longitudinal bones 21 are initially welded and fixed to the steel plate, the welding transverse moving frame 10 is moved horizontally to the corresponding position for full welding.

[0042] The welding transverse moving frame 10 drives the longitudinal moving frame 11 to move horizontally. In conjunction with the connecting seat 12, the transverse moving seat 13, and the welding vertical moving seat 14, the corresponding welding components 9 are moved to above the position to be welded. The horizontal position of the longitudinal moving frame 11 is above one end of the longitudinal bone 21. Several transverse moving seats 13 move respectively to adjust the position of the corresponding welding components 9 to correspond to the horizontal position of the joint to be welded. The welding vertical moving seat 14 is driven to descend, which drives the corresponding welding components 9 to descend. The welding components 9 are driven to move, so that the welding components 9 tilt relative to the welding vertical moving seat 14 and move closer to the joint. The welding components 9 are started. At the same time, the longitudinal moving frame 11 drives the welding components 9 to move along the joint. The welding components 9 work in pairs to weld the joints on both sides of multiple longitudinal bones 21 at the same time, completing the welding and fixing between the longitudinal bone 21 and the steel plate.

[0043] The welding assembly 9 corresponding to the assembly transverse moving frame 1 simultaneously welds a single longitudinal rib 21, while the welding assembly 9 corresponding to the welding transverse moving frame 10 simultaneously welds the joints between multiple longitudinal ribs 21 and the steel plate. This improves the efficiency of initial welding and subsequent full welding, thereby increasing the overall welding efficiency. At the same time, during welding, the assembly transverse moving frame 1 can perform initial welding and fixing on other parts of the steel plate to be assembled after material removal, improving the overall processing cycle efficiency of the longitudinal ribs 21 and the steel plate.

[0044] Example 2, as Figures 4-10 Based on Embodiment 1, both sides of the mounting bracket 16 are rotatably equipped with transmission sprockets 18, and the number of transmission sprockets 18 is set to several, see reference. Figure 8 The transmission sprockets 18 are arranged in pairs, and a chain 19 is connected between each pair of transmission sprockets 18. The number of transmission sprockets 18 on the same side of the longitudinal rib 21 is set to two. The transmission sprockets 18 at two positions at both ends of the longitudinal rib 21 are connected coaxially via a rotating shaft. A movable plate 35 is movably arranged at the bottom of the first electric push rod 17. The movable plate 35 is connected to the output end of the first electric push rod 17. Chain plates 20 are arranged on both sides of the movable plate 35. The chain plates 20 on one side of the movable plate 35 are spliced ​​together to form a plane. The two ends of the chain plates 20 are connected to the corresponding chain 19. Specifically, a single chain plate 20 is fixedly connected to a single link of the chain 19.

[0045] Both sides of the movable plate 35 are provided with fixed plates 23, and the number of fixed plates 23 is set to several, see reference. Figure 10 The fixed plate 23 is fixedly connected to the corresponding chain plate 20, and also includes a support block 22. The number of support blocks 22 is set to several, and the support blocks 22 are slidably connected to the corresponding chain plate 20. Each chain plate 20 corresponds to several support blocks 22, and the corresponding support blocks 22 are arranged at even intervals to jointly support a single longitudinal bone 21. The support blocks 22 corresponding to different chain plates 20 are used to support the corresponding longitudinal bone 21 respectively. One side of the bottom of the support block 22 is arc-shaped. The number of fixed plates 23 is adapted to the number of chain plates 20 with support blocks 22. A movable plate 24 is provided on one side of the fixed plate 23. Plate 24 is fixedly connected to the corresponding support block 22. Several No. 1 springs 25 are provided on one side of the movable plate 24. One end of the No. 1 spring 25 is fixedly connected to the fixed plate 23. Both sides of the front and rear ends of the movable plate 35 are fixedly connected to racks 34. Several transmission sprockets 18 located at the top are all connected to transmission gears 33 in a coaxial manner through a rotating shaft. The transmission gears 33 and the corresponding racks 34 mesh with each other. The vertical spacing of the support blocks 22 corresponding to the chain plates 20 at different heights is adapted to the height of the longitudinal bone 21. The support blocks 22 corresponding to the chain plates 20 at the same height are at the same height.

[0046] The working principle of this embodiment is as follows:

[0047] After the electromagnet assembly 8 completes the gripping and fixing of the longitudinal bone 21, the sliding seat 2 moves and rises, driving the electromagnet assembly 8 to rise. The electromagnet assembly 8 then drives the longitudinal bone 21 to rise, causing the longitudinal bone 21 to move to the bottom of the moving plate 35. During this process, the top two sides of the longitudinal bone 21 contact the arc-shaped surface of the support block 22, pushing the support block 22 to overcome the elastic force of the first spring 25 and contract. After the longitudinal bone 21 disengages from the support block 22, the first spring 25 pushes the support block 22 to extend out of the chain plate 20. At this time, the electromagnet assembly 8 closes, and the top of the longitudinal bone 21 falls onto the support block 22. Several support blocks 22 form multi-point support at the bottom of the longitudinal bone 21, completing the temporary support for a single longitudinal bone 21.

[0048] Next, the next longitudinal bone 21 is grasped, causing the electromagnet assembly 8 to lift the next longitudinal bone 21. The longitudinal bone 21 abuts against the bottom of the longitudinal bone 21 on the support block 22, pushing the temporarily supported longitudinal bone 21 to rise until the electromagnet assembly 8 moves the corresponding longitudinal bone 21 past the support block 22 at the bottom. The electromagnet assembly 8 is then removed from fixing the longitudinal bone 21, and the grasping and temporary fixing of the next longitudinal bone 21 is repeated to complete the temporary support of several longitudinal bones 21. Several longitudinal bones 21 are supported by support blocks 22 at different heights, and the top of the longitudinal bone 21 at the top is matched with the bottom surface of the moving plate 35.

[0049] Next, the lateral moving frame 1 is moved to the initial welding and fixing position. The sliding seat 2 descends, driving the electromagnet assembly 8 to move closer to the steel plate. The first electric push rod 17 extends, driving the moving plate 35 to descend relative to the mounting frame 16. The descent of the moving plate 35 drives the rack 34 to descend. The movement of the rack 34 drives the transmission gear 33 to rotate. The transmission gear 33 drives the corresponding transmission sprocket 18 to rotate coaxially. The rotation of the transmission sprocket 18 drives the corresponding chain 19 to rotate. The chain 19 drives the chain plate 20 to move and descend. The chain plate 20 drives the corresponding support block 22 to descend. At the same time, the moving plate 35 abuts against the top surface of the longitudinal rib 21 located at the top of the temporary support. The top and bottom surfaces of adjacent longitudinal ribs 21 contact each other. The transmission drives several longitudinal ribs 21 and the chain plate 20 to descend at the same speed until the bottom of the longitudinal rib 21 at the bottom corresponds to the electromagnet assembly 8. The electromagnet assembly 8 is then activated, adjusting the contact posture between the longitudinal rib 21 and the steel plate to prevent the longitudinal rib 21 from tilting.

[0050] The first electric push rod 17 continues to extend the rated distance, so that after the moving plate 35 descends the rated distance, the transmission drives the support block 22 located at the bottom to rotate along the arc part of the transmission sprocket 18 and move away from the lowered position of the longitudinal rib 21, removing the support for the longitudinal rib 21, until the first electric push rod 17, together with the middle longitudinal rib 21, applies pressure to the bottom longitudinal rib 21, so that the bottom longitudinal rib 21 is detached from the temporary support and contacts the steel plate in the state of being attracted by the electromagnet assembly 8, and adheres to the steel plate, completing the release of the support for the single longitudinal rib 21.

[0051] After the initial welding and fixing of the longitudinal rib 21, the first electric push rod 17 moves to the next initial welding and fixing position while maintaining the extended rated distance. The first electric push rod 17 extends the rated distance again, repeating the process of releasing a single longitudinal rib 21. This completes the material taking of multiple longitudinal ribs 21 in a single welding process, reducing the number of times the assembly transverse moving frame 1 moves back and forth between the material taking station and the assembly welding station. By taking multiple materials and releasing them for welding in sequence, the time required for the initial welding and fixing of multiple longitudinal ribs 21 is shortened, further improving the overall assembly and welding efficiency.

[0052] Example 3, as Figures 4-9 Based on Embodiment 2, a tensioning mechanism is provided on one side of the chain 19. The tensioning mechanism includes a tensioning seat 26. (See attached document) Figure 9 A tensioning sprocket 29 is rotatably mounted on one side of the tensioning seat 26. The tensioning sprocket 29 is connected to the corresponding chain 19. Limiting rods 27 are slidably sleeved on both sides of the tensioning seat 26. The limiting rods 27 are T-shaped. One end of the limiting rod 27 is fixedly connected to the mounting bracket 16. The tensioning seat 26 can slide axially without disengaging from the limiting rods 27. A second spring 28 is movably sleeved on the outer side of the limiting rod 27. The second spring 28 is used to push the tensioning seat 26 away from the chain 19 to increase the tension of the chain 19. A second electric push rod 32 is mounted on one side of the chain 19. The output end of the second electric push rod 32 is connected to an adjusting seat 30. Adjusting sprockets 31 are rotatably mounted on the top and bottom of the adjusting seat 30. The adjusting sprockets 31 are connected to the corresponding chain 19.

[0053] Both sides of the chain plate 20, which is equipped with support blocks 22, are fixedly connected to connecting blocks 36. (See reference) Figure 10 A sliding rod 37 is slidably connected to one side of the connecting block 36. Two corresponding sliding rods 37 at the same height are in contact with each other. A No. 3 spring 40 is movably installed on the inner side of the connecting block 36. The No. 3 spring 40 is used to push the sliding rod 37 out of the connecting block 36. One end of the sliding rod 37 is an inclined surface. An adjusting rod 38 is slidably engaged at one end of the inclined surface of the sliding rod 37. The adjusting rod 38 is slidably sleeved with the connecting block 36. The adjusting rod 38 can slide axially relative to the connecting block 36. The adjusting rod 38 can slide relative to the sliding rod 37 without disengaging from the sliding rod 37. The inclined part of the sliding rod 37 is used to adjust the extension length of the adjusting rod 38 relative to the connecting block 36, thereby adjusting the distance between the adjusting rod 38 and the temporary support longitudinal bone 21. An adjusting plate 39 is fixedly connected to one end of the adjusting rod 38. The adjusting plate 39 is used for horizontal limiting of the longitudinal bone 21.

[0054] The working principle of this embodiment is as follows:

[0055] After providing temporary support for multiple longitudinal ribs 21, the second electric push rod 32 extends, driving the adjusting seat 30 to move. The adjusting seat 30 then drives the corresponding two adjusting sprockets 31 to move simultaneously by a rated distance, causing the chains 19 on both sides of the longitudinal rib 21 to bring the chain plates 20 closer together. This allows the chain plates 20 to limit the sidewalls of the longitudinal rib 21, ensuring the feeding posture of the longitudinal rib 21. This, combined with the electromagnet assembly 8, ensures stable material reception on the longitudinal rib 21 and allows the distance between the two opposing chain plates 20 to be set to a large value. The width of the longitudinal rib 21 allows for a gap between the chain plate 20 and the longitudinal rib 21 during the feeding process. This prevents errors caused by the specifications or misalignment of the longitudinal rib 21 from causing temporary fixation failure after gripping and requiring re-gripping. It also reduces wear between the longitudinal rib 21 and the chain plate 20 during feeding. In the subsequent feeding process, the chain plate 20 and the longitudinal rib 21 move synchronously, ensuring guidance while further reducing wear between them, thus improving the reliability and service life of the equipment.

[0056] Chain 19 drives two corresponding chain plates 20 to move closer to each other, chain plates 20 drive two corresponding connecting blocks 36 to move closer to each other, two sliding rods 37 abut against each other and move and retract relative to the corresponding connecting blocks 36, the inclined part of the connecting block 36 drives the adjusting rod 38 to extend out of the connecting block 36, the adjusting rod 38 drives the adjusting plate 39 to move closer to the longitudinal rib 21, completing the end limit of the longitudinal rib 21. During the lowering process of the longitudinal rib 21, the adjusting plate 39 moves synchronously to the longitudinal rib 21 and provides guidance, ensuring the stability of the longitudinal rib 21 during the descent process while reducing the wear between the longitudinal rib 21 and the adjusting plate 39, further improving the reliability and service life of the equipment.
