Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to a welding flipping platform structure based on intersecting nodes of multiple pipes and its operation method. Background Technology

[0002] Steel pipes are steel materials with a hollow cross-section, whose length is much greater than its diameter or circumference. They are classified according to their uses into steel pipes for transportation pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, and high-pressure equipment.

[0003] Steel pipes can be used to transport fluids and powdery solids, exchange heat energy, and manufacture mechanical parts and containers. When steel pipes are used for transportation, the working environment requires the pipes to be connected. Therefore, a number of branch pipes are welded around the main pipe to complete the subsequent diversion and transportation. Therefore, a welding platform is needed to fix the main pipe and branch pipes in place in preparation for the subsequent welding work.

[0004] Currently available welding platforms cannot simultaneously clamp and connect multiple branch pipes to the main pipe at the same time when welding intersecting nodes. Therefore, multiple branch pipes must be welded to the main pipe at their respective intersection positions before the next branch pipe is welded. This greatly increases the number of welding steps, prolongs the welding time, and is time-consuming and labor-intensive. Furthermore, after each welding operation, disassembly and clamping work must be repeated to prepare for the welding of the next branch pipe, increasing the labor intensity and the difficulty of repeated debugging. Summary of the Invention

[0005] The purpose of this invention is to provide a welding flipping platform structure and its operation method based on multi-pipe intersecting nodes to solve the above-mentioned technical problems.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.

[0007] This invention relates to a welding flipping platform structure based on multi-pipe intersecting nodes, comprising a workbench, a fixed frame mounted on one side of the workbench, a ring frame fixedly mounted on the fixed frame, a ring component concentrically rotatably mounted on the ring frame, a driving mechanism installed between the ring frame and the ring component, the driving mechanism driving the ring component to rotate on the ring frame to complete the flipping action, multiple limiting mechanisms arranged in a circular array on the side of the ring component away from the ring frame, each of the multiple limiting mechanisms being mounted with a branch pipe, two No. 1 cylinders mounted on the side of the ring component away from the limiting mechanisms via a bracket, the two No. 1 cylinders being symmetrically distributed at the top and bottom of the ring component, an arc-shaped pressure plate being installed at the output end of each of the two No. 1 cylinders, a main pipe concentrically arranged between the two arc-shaped pressure plates and the ring component, multiple branch pipes completing contact action with the main pipe through multiple limiting mechanisms, and a reinforcement mechanism added to each of the multiple limiting mechanisms to complete the reinforcement action between the limiting mechanisms and the ring component.

[0008] Furthermore, the driving mechanism includes a first gear ring concentrically sleeved on the outer wall of the annular component, a reduction motor mounted on one side of the fixed frame via a bracket, a gear mounted on the output end of the reduction motor, the gear meshing and driving with the first gear ring, an annular scale strip provided at the edge of the outer wall of the annular component, an annular track recessed inward on the side of the annular component away from the annular frame, and a second gear ring mounted on the inner wall of the annular component away from the annular frame.

[0009] Furthermore, a manual slide is installed on the upper surface of the workbench on one side of the fixed frame, a cylinder is installed at the output end of the manual slide, and an arc-shaped support plate is installed at the output end of the cylinder.

[0010] Furthermore, each of the multiple limiting mechanisms includes a sliding component that is slidably installed in a circular track. A lifting frame is fixedly installed at the front end of the sliding component, and a lifting block is slidably installed inside the lifting frame. A lifting screw is threaded through the top of the lifting frame, and the bottom of the lifting screw is rotatably connected to the top of the lifting block. An arc-shaped toothed plate is installed inside the lifting block, and the arc-shaped toothed plate meshes with the second toothed ring to fix the lifting frame.

[0011] Furthermore, a second manual slide is installed on the outside of the lifting block, a connecting frame is installed at the output end of the second manual slide, a circular frame is installed at the front end of the connecting frame, and two arc-shaped clamps are symmetrically installed inside the circular frame. Adjusting screws are rotatably installed on the side walls of the two arc-shaped clamps. The two adjusting screws are threaded through the circular frame, and the position of the arc-shaped clamps on the circular frame is adjusted by adjusting the screws. Guide rods are installed on the side walls of the two arc-shaped clamps on the side of the adjusting screws. The two guide rods slide through the circular frame, and the movement of the arc-shaped clamps is guided by the outside of the guide rods. The two arc-shaped clamps are fixed on the circular frame.

[0012] Furthermore, a pointer is installed on one side of the lifting frame, which points toward the circular scale bar for indication.

[0013] Furthermore, the reinforcement mechanism includes a through-hole area formed in the slide, in which a positive and negative threaded rod is rotatably installed. Two threaded rod nuts are symmetrically sleeved on the outside of the positive and negative threaded rods, and the two threaded rod nuts are slidably connected to the inner wall of the through-hole area. The positive and negative threaded rods drive the two threaded rod nuts to move closer and further apart. A reinforcement plate is slidably installed at the top of the through-hole area, and two linkage arms are symmetrically hinged to the lower surface of the reinforcement plate. The bottom of the two linkage arms is respectively hinged to the top of the two threaded rod nuts. The two threaded rod nuts and the linkage arms complete the pushing of the reinforcement plate.

[0014] Furthermore, a drive shaft is rotatably mounted on the front end face of the sliding component. This drive shaft is connected to the forward and reverse threaded screws. A drive gear is fixedly sleeved on the outside of the drive shaft. A rack is vertically mounted on the upper surface of the lifting block. This rack is meshed with the drive gear and connected to the drive gear. The rack and drive gear work together to drive the forward and reverse threaded screws to complete the driving of the reinforcing plate. The forward and reverse threaded screws, screw nuts, and drive gears are adapted to each other. When the rack moves upward to push the drive gear, the two screw nuts move closer to each other on the forward and reverse threaded screws. When the rack moves downward to push the drive gear, the two screw nuts move further away from each other on the forward and reverse threaded screws.

[0015] Furthermore, the drive gear extends into the lifting frame, and the drive gear does not contact the lifting screw. When the lifting block moves upward, the rack and drive gear drive the reinforcing plate to move upward to complete the reinforcement and restriction.

[0016] This invention also provides an operation method for a welding flipping platform structure based on multi-pipe intersecting nodes, which specifically includes the following steps:

[0017] Step 1: First, remove the main pipe and multiple branch pipes for later use, awaiting subsequent clamping and welding work;

[0018] Step 2: Then insert the main pipe into the ring-shaped part, and then start the two No. 1 cylinders to push the arc-shaped pressure plate to move and clamp and fix the main pipe in the ring-shaped part to ensure the stability of the main pipe;

[0019] Step 3: Then, multiple branch pipes are assembled and installed on multiple limiting mechanisms. The multiple limiting mechanisms are used to clamp and fix the multiple branch pipes. Since the limiting mechanism can rotate freely on the ring, it can be freely adjusted to different positions, making it more adaptable. It can be freely adjusted to the welding position reserved on the main pipe. After the adjustment is completed, the limiting mechanism is used to make a fine adjustment of the welding height of the branch pipes, so that the multiple branch pipes intersect and contact the main pipe. Then, the welding work of the intersection node of the multiple branch pipes and the main pipe is completed by welding equipment.

[0020] Step 4: Under the action of the drive mechanism, the drive ring rotates and the main pipe and multiple branch pipes follow the rotation and flip, which makes it easy to flip multiple branch pipes to the vicinity of the welding equipment, making the overall welding work convenient and fast.

[0021] Step 5: Under the action of the reinforcement mechanism, when the limiting mechanism is fixed on the ring part, the limiting mechanism acts synchronously on the reinforcement mechanism, driving the reinforcement mechanism to complete the internal expansion contact, which improves the stability of the limiting mechanism and avoids the problem of the branch pipe shifting during the welding action, affecting the welding accuracy.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This invention uses a limiting mechanism to move the arc-shaped clamping plate on the ring frame to clamp the branch pipe on both sides. The second manual slide table moves the ring frame and the branch pipe on it up and down, so that the branch pipe is in stable contact with the main pipe, which is convenient for subsequent welding. Since the branch pipe can rotate on the ring part with the limiting mechanism to complete the position adjustment, it is convenient for the operator to operate freely. After the adjustment is completed, simply pull the lifting block in the lifting frame with the corresponding lifting screw to drive the arc-shaped toothed plate to reset and mesh with the second toothed ring to lock the limiting mechanism.

[0024] 2. The present invention has a drive mechanism. By simply starting the reduction motor, the power is transmitted to the first gear ring through the gears, driving the ring part to rotate on the ring frame to complete the flipping action. The main tube on the ring part and multiple main tubes follow the flipping action to complete the adjustment of the welding station, which makes welding easier and makes the welding work more time-saving and labor-saving.

[0025] 3. The present invention has a reinforcement mechanism. During the resetting and moving stroke of the lifting block, the rack moves upward and drives the gear to rotate, transmitting power to the positive and negative threaded rods. The positive and negative threaded rods rotate to drive the two threaded rod nuts. When the two threaded rod nuts approach each other, the linkage arm pushes the reinforcement plate to move upward in the penetration area, so that the reinforcement plate and the anti-slip pad on it carry a certain pressure and rub against the inner wall of the annular track, avoiding the problem of displacement of the limiting mechanism.

[0026] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0041] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0042] Example 1: The present invention provides a technical solution: such as Figures 1-6 As shown, the welding flipping platform structure based on the multi-pipe intersecting node includes a workbench 1, a fixed frame 2 installed on one side of the workbench 1, a ring frame 3 fixedly installed on the fixed frame 2, a ring component 4 concentrically rotated on the ring frame 3, a driving mechanism installed between the ring frame 3 and the ring component 4, the driving mechanism is used to drive the ring component 4 to rotate on the ring frame 3 to complete the flipping action, multiple limiting mechanisms are arranged in a circular array on the side of the ring component 4 away from the ring frame 3, and branch pipes 5 are installed on each of the multiple limiting mechanisms, and two No. 1 cylinders 6 are installed on the side of the ring component 4 away from the limiting mechanisms by a bracket, the two No. 1 cylinders 6 are symmetrically distributed at the top and bottom of the ring component 4, and arc-shaped pressure plates 7 are installed at the output ends of the two No. 1 cylinders 6, a main pipe 8 is arranged concentrically with the ring component 4 between the two arc-shaped pressure plates 7, the multiple branch pipes 5 complete the contact action with the main pipe 8 through the multiple limiting mechanisms, and a reinforcing mechanism is added to each of the multiple limiting mechanisms to complete the reinforcement action between the limiting mechanism and the ring component 4.

[0043] It is worth noting that when the main pipe 8 and branch pipe 5 intersect, the main pipe 8 is clamped and fixed by two No. 1 cylinders 6, so that the main pipe 8 is stably and concentrically installed in the annular part 4, and one end of the main pipe 8 contacts the arc-shaped support plate 17. The arc-shaped support plate 17 is used to lift the main pipe 8. At the same time, under the guidance of the rotation of multiple rotating wheels, the main pipe 8 can be rotated more smoothly, improving the stability of the main pipe 8 and avoiding the impact of the length of the main pipe 8 on stability. The position of the arc-shaped support plate 17 can be adjusted back and forth by the No. 1 manual slide table 15, and the height of the arc-shaped support plate 17 can be adjusted by the No. 2 cylinder 16. It can be adjusted for different sizes of main pipe 8. Then, the branch pipe 5 is installed on the limiting mechanism. The limiting mechanism drives the branch pipe 5 to contact the main pipe 8 to complete the intersecting action. Afterwards, the connection between the main pipe 8 and the branch pipe 5 can be welded.

[0044] In this embodiment of the invention, the driving mechanism includes a first gear ring 9 concentrically sleeved on the outer wall of the annular part 4, a reduction motor 10 mounted on one side of the fixed frame 2 via a bracket, a gear 11 mounted on the output end of the reduction motor 10, the gear 11 meshing and transmitting with the first gear ring 9, an annular scale strip 12 provided at the edge of the outer wall of the annular part 4, an annular track 13 recessed inward on the side of the annular part 4 away from the annular frame 3, a second gear ring 14 mounted on the inner wall of the annular part 4 away from the annular frame 3, a first manual slide 15 mounted on the upper surface of the worktable 1 on one side of the fixed frame 2, a second cylinder 16 mounted on the output end of the first manual slide 15, an arc-shaped support plate 17 mounted on the output end of the second cylinder 16, and multiple rotating wheels evenly distributed on the inner wall of the arc-shaped support plate 17, all of which are rotatably disposed within the arc-shaped support plate 17.

[0045] It is worth noting that during the flipping process, the drive mechanism allows the reduction motor 10 to be started, which transmits power to the first gear ring 9 via the gear 11. This drives the ring part 4 to rotate on the ring frame 3, completing the flipping action. The main tube 8 and multiple main tubes 8 on the linked ring part 4 also follow the flipping action to adjust the welding station, making welding easier and saving time and effort in the welding work.

[0046] All electrical components on the drive mechanism are connected to switches via wires, and the switches are electrically connected to controllers. The specific structure of the controllers is not limited. An absolute encoder is installed on the geared motor 10 on the drive mechanism for accurate positioning.

[0047] Example 2: Based on the limiting mechanism provided in Example 1, this example provides a further technical solution for the limiting mechanism.

[0048] like Figures 7-10 As shown, each of the multiple limiting mechanisms includes a sliding member 18 that is slidably installed in the annular track 13. A lifting frame 19 is fixedly installed at the front end of the sliding member 18. A lifting block 20 is slidably installed inside the lifting frame 19. A lifting screw 21 is threaded through the top of the lifting frame 19. The bottom of the lifting screw 21 is rotatably connected to the top of the lifting block 20. An arc-shaped toothed plate 22 is installed inside the lifting block 20. The arc-shaped toothed plate 22 meshes with the second toothed ring 14 to fix the lifting frame 19.

[0049] It is worth noting that when fixing the branch pipe 5: A limiting mechanism is provided. First, the branch pipe 5 is threaded onto the ring frame 25. Then, the adjusting screw 27 is rotated accordingly, pushing the arc-shaped clamp 26 to move on the ring frame 25 to clamp the branch pipe 5 on both sides. The guide rod 28 guides the movement of the arc-shaped clamp 26. The overall installation and disassembly are convenient and quick. Subsequent adjustments only require the second manual slide 23. The second manual slide 23 moves the ring frame 25 and the branch pipe 5 up and down, ensuring stable contact between the branch pipe 5 and the main pipe 8, facilitating subsequent welding. Because the branch pipe 5 can... The position adjustment is completed by the rotation of the limiting mechanism on the ring part 4. Therefore, during the specific adjustment, the arc-shaped toothed plate 22 is first driven to separate from the second toothed ring 14 by the lifting screw 21. Then, the ring frame 25 follows the slide 18 to freely adjust the position in the ring track 13. The pointer 29 and the ring scale bar 12 are used to indicate the adjustment range of multiple limiting mechanisms, which is convenient for the staff to operate freely. Finally, after the adjustment is completed, the lifting block 20 is pulled up in the lifting frame 19 according to the corresponding lifting screw 21, which drives the arc-shaped toothed plate 22 to reset and engage with the second toothed ring 14 to lock the limiting mechanism.

[0050] In this embodiment of the invention, a second manual slide table 23 is installed on the outside of the lifting block 20. A connecting frame 24 is installed at the output end of the second manual slide table 23. A circular frame 25 is installed at the front end of the connecting frame 24. Two arc-shaped clamping plates 26 are symmetrically installed inside the circular frame 25. Adjusting screws 27 are rotatably installed on the side walls of the two arc-shaped clamping plates 26. The two adjusting screws 27 are threaded through the circular frame 25. The position of the arc-shaped clamping plates 26 on the circular frame 25 is adjusted by adjusting the screws 27. Guide rods 28 are installed on the side walls of the two arc-shaped clamping plates 26 on the side of the adjusting screws 27. The two guide rods 28 slide through the circular frame 25. The two arc-shaped clamping plates 26 are fixed on the circular frame 25 by guiding the movement of the arc-shaped clamping plates 26 through the outside of the guide rods 28. A pointer 29 is installed on one side of the lifting frame 19. The pointer 29 faces the annular scale bar 12 for indication.

[0051] Example 3: Based on the reinforcement mechanism provided in Example 1, this example provides a further technical solution for the reinforcement mechanism.

[0052] like Figure 11 and Figure 12As shown, the reinforcement mechanism includes a through area 30 that extends through the slide 18. A positive and negative threaded rod 31 is rotatably installed in the through area 30. Two threaded rod nuts 32 are symmetrically sleeved on the outside of the positive and negative threaded rod 31. The threaded rod nuts 32 have threaded grooves that mate with the positive and negative threaded rod 31. The two threaded rod nuts 32 are slidably connected to the inner wall of the through area 30. The positive and negative threaded rod 31 drives the two threaded rod nuts 32 to move closer and further away from each other through forward and reverse rotation. A reinforcement plate 33 is slidably installed at the top of the through area 30. Two linkage arms 34 are symmetrically hinged to the lower surface of the reinforcement plate 33. The bottom of the two linkage arms 34 is respectively hinged to the top of the two threaded rod nuts 32. The two threaded rod nuts 32 and the linkage arms 34 push the reinforcement plate 33. An anti-slip pad is installed on the upper surface of the reinforcement plate 33. The anti-slip pad is detachably fixed to the reinforcement plate 33 by bolts.

[0053] It is worth noting that during reinforcement: by providing a reinforcement mechanism, when the lifting screw 21 pulls the lifting block 20 and the arc-shaped toothed plate 22 to move upward and reset to mesh with the second gear ring 14, during the resetting and upward movement of the lifting block 20, the rack 37 is driven to move upward as well. Since the rack 37 is meshed with the drive gear 36, the rack 37 rotates in conjunction with the drive gear 36 when it moves upward, and transmits power to the positive and negative threaded rods 31. The positive and negative threaded rods 31 rotate to drive the two threaded rod nuts 32, causing the two threaded rod nuts 32 to move closer to each other. When the two threaded rod nuts 32 move closer to each other, the linkage arm 34 pushes the reinforcement plate 33 to move upward within the through area 30, so that the reinforcement plate 33 and the anti-slip pad on it carry a certain pressure and rub against the inner wall of the annular track 13, which improves the stability of the limiting mechanism, avoids the problem of displacement of the limiting mechanism, and makes the welding work more precise.

[0054] In this embodiment of the invention, a drive shaft 35 is rotatably mounted on the front end face of the slider 18. The drive shaft 35 is connected to the positive and negative threaded rod 31. A drive gear 36 is fixedly sleeved on the outside of the drive shaft 35. A rack 37 is vertically mounted on the upper surface of the lifting block 20. The rack 37 is meshed with the drive gear 36. The rack 37 and the drive gear 36 act on the positive and negative threaded rod 31 to drive the reinforcing plate 33. The positive and negative threaded rod 31, the threaded rod nut 32, and the drive gear 36 are adapted to each other. When the rack 37 moves upward and pushes the drive gear 36, the two rods move in tandem. The two lead screw nuts 32 move closer to each other on the positive and negative threaded screws 31. When the rack 37 moves down and pushes the drive gear 36, the two lead screw nuts 32 move further away from each other on the positive and negative threaded screws 31. When the arc-shaped toothed plate 22 meshes with the second gear ring 14, the reinforcing plate 33 moves out a certain distance and contacts the annular track 13 to complete the reinforcement and restriction. The drive gear 36 extends into the lifting frame 19, and the drive gear 36 does not contact the lifting screw 21. When the lifting block 20 moves up, the reinforcing plate 33 is driven to move up through the rack 37 and the drive gear 36 to complete the reinforcement and restriction.

[0055] Example 4: Operation method of welding flipping platform structure based on multi-pipe intersecting nodes. The operation method specifically includes the following steps:

[0056] Step 1: First, remove the main pipe 8 and multiple branch pipes 5 for later use, awaiting subsequent clamping and welding work;

[0057] Step 2: Then insert the main pipe 8 into the annular part 4, and then start the two No. 1 cylinders 6 to push the arc-shaped pressure plate 7 to move and clamp the main pipe 8 in the annular part 4 to ensure the stability of the main pipe 8;

[0058] Step 3: Then, multiple branch pipes 5 are assembled and installed on multiple limiting mechanisms. The multiple limiting mechanisms are used to clamp and fix the multiple branch pipes 5. Since the limiting mechanism can rotate freely on the ring part 4, the limiting mechanism can be freely adjusted to different positions, making it more adaptable. It can be freely adjusted to the welding position reserved on the main pipe 8. After the adjustment is completed, the welding height of the branch pipes 5 is finely adjusted up and down using the limiting mechanism, so that the multiple branch pipes 5 intersect and contact with the main pipe 8. Subsequently, the welding work of the intersection node of the multiple branch pipes 5 and the main pipe 8 is completed by welding equipment.

[0059] Step 4: Under the action of the drive mechanism, the drive ring 4 rotates and the main pipe 8 and multiple branch pipes 5 follow the rotation and flip, which makes it easy to flip the multiple branch pipes 5 to the vicinity of the welding equipment, making the overall welding work convenient and fast.

[0060] Step 5: Under the action of the reinforcement mechanism, when the limiting mechanism is fixed on the ring part 4, the limiting mechanism acts synchronously on the reinforcement mechanism, driving the reinforcement mechanism to complete the internal expansion contact within the through area 30, which improves the stability of the limiting mechanism and avoids the problem of the branch pipe 5 shifting during the welding action, affecting the welding accuracy.

[0061] This invention provides a welding flipping platform structure and its operation method based on multi-pipe intersecting nodes. The specific working principle is as follows: First, the main pipe 8 and multiple branch pipes 5 are taken out for later use and waiting for subsequent clamping and welding work. Then, the main pipe 8 is inserted into the annular part 4. After that, two cylinders 6 are activated to push the arc-shaped pressure plate 7 to move and clamp and fix the main pipe 8 in the annular part 4, thus ensuring the stability of the main pipe 8.

[0062] Then, multiple branch pipes 5 are assembled and installed on multiple limiting mechanisms. The multiple limiting mechanisms are used to clamp and fix the multiple branch pipes 5. Since the limiting mechanism can be freely rotated and adjusted on the ring part 4, the limiting mechanism can be freely adjusted to different positions, making it more adaptable. It can be freely adjusted to the welding position reserved on the main pipe 8. After the adjustment is completed, the welding height of the branch pipes 5 is finely adjusted up and down using the limiting mechanism, so that the multiple branch pipes 5 intersect and contact the main pipe 8. Subsequently, the welding work of the intersection node of the multiple branch pipes 5 and the main pipe 8 is completed by the welding equipment. Under the action of the driving mechanism, the ring part 4 is driven to rotate and the main pipe 8 and multiple branch pipes 5 follow the rotation and flip, making it convenient to flip the multiple branch pipes 5 to the vicinity of the welding equipment, making the overall welding work convenient and fast.

[0063] Simultaneously, under the action of the reinforcement mechanism, when the limiting mechanism is fixed on the annular part 4, the limiting mechanism acts synchronously on the reinforcement mechanism, driving the reinforcement mechanism to complete the internal expansion contact with the annular track 13 within the through area 30, thereby improving the stability of the limiting mechanism and avoiding the problem of the branch pipe 5 shifting during the welding action, which affects the welding accuracy.

An operation method for a welding flipping platform structure based on multi-pipe intersecting nodes, characterized in that: The welding flipping platform structure based on any one of claims 1-7, and the operation method specifically includes the following steps: Step 1: First, take out the main pipe (8) and multiple branch pipes (5) for later use, and wait for subsequent clamping and welding work; Step 2: Then insert the main pipe (8) into the ring part (4), and then start the two No. 1 cylinders (6) to push the arc-shaped pressure plate (7) to move and clamp the main pipe (8) in the ring part (4) to ensure the stability of the main pipe (8); Step 3: Then, multiple branch pipes (5) are assembled and installed on multiple limiting mechanisms. Multiple branch pipes (5) are clamped and fixed by multiple limiting mechanisms. Since the limiting mechanism can rotate freely on the ring part (4), the limiting mechanism can be freely adjusted to different positions, making it more adaptable. It can be freely adjusted for the welding position reserved on the main pipe (8). After the adjustment is completed, the welding height of the branch pipes (5) is finely adjusted up and down by using the limiting mechanism, so that multiple branch pipes (5) and the main pipe (8) intersect and contact. Then, the welding work of the intersection node of multiple branch pipes (5) and the main pipe (8) is completed by welding equipment. Step 4: Under the action of the driving mechanism, the driving ring (4) rotates and the main pipe (8) and multiple branch pipes (5) follow the rotation and flip, so that multiple branch pipes (5) can be flipped to the vicinity of the welding equipment, making the overall welding work convenient and fast; Step 5: Under the action of the reinforcement mechanism, when the limiting mechanism is fixed on the ring part (4), the limiting mechanism acts synchronously on the reinforcement mechanism, driving the reinforcement mechanism to complete the internal expansion contact, improving the stability of the limiting mechanism, and avoiding the problem of the branch pipe (5) shifting during the welding action, which affects the welding accuracy.
