[0002] In the field of hydrogen pipeline processing, pipeline clamping and conveying are key steps in achieving automated cutting. With the rapid development of the hydrogen energy industry, higher demands are being placed on pipeline processing precision, efficiency, and compatibility. Traditional pipeline processing equipment has significant shortcomings in areas such as adaptive clamping of multi-specification pipelines, stability control during the cutting process, and power transmission synchronization, making it difficult to meet the needs of modern large-scale, precision production of hydrogen pipelines.

[0003] The shortcomings of existing technology:

[0004] 1. Poor adaptability of clamping mechanism: Traditional processing equipment mostly uses clamping devices with fixed spacing, which is difficult to be compatible with hydrogen energy pipelines of different specifications. When changing molds, the machine needs to be stopped for adjustment, resulting in low production efficiency.

[0005] 2. Low cutting accuracy and automation: Cutting methods with manual positioning or mechanical limiting are easily affected by human error and cannot be linked with the conveying system, making it difficult to achieve continuous production. Utility Model Content

[0006] In order to solve the problems mentioned in the background art, the present invention provides a clamping and support mechanism for hydrogen energy pipeline processing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

A first annular bracket and a second annular bracket are respectively provided on both sides of the top of the support base. Multiple sets of clamping and conveying mechanisms are installed between the first annular bracket and the second annular bracket. The multiple sets of clamping and conveying mechanisms are evenly distributed in a ring, and the spacing between the multiple sets of clamping and conveying mechanisms is adjustable.

[0009] A vertical drive box is installed on the side of the second annular bracket away from the first annular bracket, and a laser cutter is installed at the output end of the vertical drive box;

[0010] The clamping and conveying mechanism includes a horizontally arranged feeding conveyor belt, on the surface of which multiple clamping plates are equidistantly distributed, and the clamping plates are elastically connected to the feeding conveyor belt.

[0012] Preferably, the first annular support and the second annular support are provided with a connecting crossbeam, the clamping and conveying mechanism is fixed on the connecting crossbeam, and an adjusting ring is rotatably installed on the side of the first annular support and the second annular support that are close to each other, and an arc-shaped guide opening is provided on the adjusting ring.

[0013] Preferably, both ends of the connecting crossbeam are fixed with guide posts, the guide posts pass through the adjusting ring through the arc-shaped guide opening, and the first annular bracket and the second annular bracket are provided with slide rails on their respective sides, and the end of the guide post away from the connecting crossbeam is slidably mounted on the slide rail.

[0014] Preferably, the outer side of the adjusting ring has a continuous distribution of meshing teeth, the first ring bracket and the second ring bracket are rotatably mounted with a first drive shaft, the outer side of the first drive shaft is fixed with two first spur gears, the two first spur gears respectively mesh with the meshing teeth on the two adjusting rings, and the first drive shaft is driven to rotate by a first servo motor.

[0015] Preferably, the feeding conveyor belt is provided with a power input shaft, the top end of the power input shaft is provided with a spline shaft, and multiple second connecting frames are fixed on the side of the first annular bracket and the second annular bracket that are close to each other.

[0016] Preferably, a transmission horizontal shaft is rotatably mounted on the second connecting frame, a first bevel gear and a second spur gear are fixed on the transmission horizontal shaft, a second bevel gear is fixed at the top of the transmission vertical shaft, the second bevel gear meshes with the first bevel gear, one of the transmission horizontal shafts is driven to rotate by a second servo motor, and a synchronous gear ring is rotatably mounted on the side of the first annular bracket away from the second annular bracket, and multiple second spur gears mesh with the synchronous gear ring.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0041] Reference Figure 1-17 A clamping support mechanism for processing hydrogen energy pipelines includes a clamping support mechanism and a material transfer mechanism. The clamping support mechanism includes a support base 1. A first annular bracket 2 and a second annular bracket 201 are respectively provided on both sides of the top of the support base 1. Multiple sets of clamping and conveying mechanisms 3 are installed between the first annular bracket 2 and the second annular bracket 201. The multiple sets of clamping and conveying mechanisms 3 are evenly distributed in a ring, and the spacing between the multiple sets of clamping and conveying mechanisms 3 is adjustable.

[0042] During loading, the worker inserts one end of the long pipe to be cut into the space between multiple clamping and conveying mechanisms 3 through the first annular bracket 2. By adjusting the spacing between the multiple clamping and conveying mechanisms 3, the long pipe can be clamped and fixed. The clamping and conveying mechanism 3 includes a horizontally arranged feeding conveyor belt 301. Multiple clamping plates 302 are evenly distributed on the surface of the feeding conveyor belt 301. The clamping plates 302 are elastically connected to the feeding conveyor belt 301. By the synchronous operation of multiple feeding conveyor belts 301, the long pipe can be pushed to move horizontally to achieve the purpose of loading and conveying. The long pipe passes through the second annular bracket 201.

[0043] A vertical drive box 7 is installed on the side of the second ring bracket 201 away from the first ring bracket 2, and a laser cutter 701 is installed at the output end of the vertical drive box 7.

[0044] After passing through the second annular support 201, the long tube moves to the cutting station of the laser cutting machine 701. By driving the long tube to move a specific length each time, a fixed-length cut can be performed.

[0045] With higher processing efficiency, the clamping and conveying mechanism 3 can integrate the functions of clamping stability and feeding during the cutting process.

[0046] The material unloading and transfer mechanism includes a material unloading conveyor belt 4 and a material unloading transfer vehicle. The material unloading conveyor belt 4 is fixed to the side of the second annular bracket 201 away from the first annular bracket 2 by a mounting bracket 401.

[0047] The cut short pipes fall onto the unloading conveyor belt 4 and are transferred one by one to the unloading transfer car, which then transfers them to the next processing station for further processing. Example 2

[0048] Reference Figure 1-17 The difference between this embodiment and Embodiment 1 is that the clamping and conveying mechanism 3 includes a horizontally arranged feeding conveyor belt 301. Multiple clamping plates 302 are evenly distributed on the surface of the feeding conveyor belt 301. The clamping plates 302 are elastically connected to the feeding conveyor belt 301. A first connecting frame 303 is fixed on the feeding conveyor belt 301. A horizontal guide rod 304 is fixed on the side of the clamping plate 302 near the feeding conveyor belt 301. Two sliding members 305 are slidably installed on the horizontal guide rod 304, and the outer part of the horizontal guide rod 304 is sleeved between the two horizontal guide rods 304. There is a spring 306, and both sides of the first connecting frame 303 are hinged to two sliding parts 305 through connecting rods 307. When multiple clamping and conveying mechanisms 3 move towards each other, multiple clamping plates 302 move closer to each other, so that the pipe is clamped evenly around the perimeter. During the clamping process, the spring 306 is compressed and the two sliding parts 305 move closer to each other, which plays a buffering role and can clamp the pipe more stably, preventing slippage during the conveying process. It can also make adaptive adjustments for pipes of different diameters and can clamp pipes of various sizes. Example 3

[0049] Reference Figure 1-17 The difference between this embodiment and Embodiment 2 is that the first annular support 2 and the second annular support 201 are provided with a connecting crossbeam 308, and the clamping and conveying mechanism 3 is fixed on the connecting crossbeam 308. Adjusting rings 202 are rotatably mounted on the sides of the first annular support 2 and the second annular support 201 that are close to each other. An arc-shaped guide opening 203 is provided on the adjusting ring 202. Guide posts 309 are fixed at both ends of the connecting crossbeam 308. The guide posts 309 pass through the arc-shaped guide opening 203 and penetrate the adjusting ring 202. Furthermore, the first annular support 2 and the second annular support 201 are mutually... A slide rail 204 is provided on the side closest to the guide post 309. The end of the guide post 309 away from the connecting crossbeam 308 is slidably mounted on the slide rail 204. A section of meshing teeth 205 is continuously distributed on the outside of the adjusting ring 202. The first ring bracket 2 and the second ring bracket 201 are rotatably mounted with the first drive shaft 206. Two first straight gears 207 are fixed on the outside of the first drive shaft 206. The two first straight gears 207 respectively mesh with the meshing teeth 205 on the two adjusting rings 202. The first drive shaft 206 is driven to rotate by the first servo motor 208.

[0050] To adjust the spacing between the various clamping and conveying mechanisms 3 to clamp and release the pipe fittings, the first servo motor 208 is started. The first servo motor 208 drives the first drive shaft 206 to rotate. Through the engagement of the first spur gear 207 and the meshing gear 205, the two adjusting rings 202 can be driven to rotate synchronously. Since the adjusting rings 202 rotate relative to the first annular bracket 2 and the second annular bracket 201, the guide post 309 slides in the arc-shaped guide opening 203. With the guidance and limit of the slide rail 204, the guide post 309 can be driven to slide along the slide rail 204, thereby causing the connecting crossbeams 308 to converge and separate, thereby adjusting the spacing between the various clamping and conveying mechanisms 3. Example 4

[0051] Reference Figure 1-17 The difference between this embodiment and embodiment 3 is that a power input shaft 6 is provided on the feeding conveyor belt 301, and a spline shaft 601 is provided at the top of the power input shaft 6. Multiple second connecting frames 602 are fixed on the side of the first annular bracket 2 and the second annular bracket 201 that are close to each other. A transmission vertical shaft 603 is rotatably mounted on the second connecting frame 602. The bottom end of the transmission vertical shaft 603 is movably sleeved on the outside of the spline shaft 601. A transmission horizontal shaft 605 is rotatably mounted on the second connecting frame 602. A first bevel gear 606 and a second spur gear 608 are fixed on the transmission horizontal shaft 605. A second bevel gear 604 is fixed at the top of the transmission vertical shaft 603. The second bevel gear 604 meshes with the first bevel gear 606. One of the transmission horizontal shafts 605 is driven to rotate by a second servo motor 607. A synchronous gear ring 609 is rotatably mounted on the side of the first annular bracket 2 away from the second annular bracket 201. Multiple second spur gears 608 mesh with the synchronous gear ring 609.

[0052] To drive the synchronous operation of each feeding conveyor belt 301 and ensure a smoother conveying process, when the second servo motor 607 is turned on, it drives one of the transmission horizontal shafts 605 to rotate. Through the meshing of multiple second spur gears 608 with the synchronous gear ring 609, the other transmission horizontal shafts 605 can also rotate synchronously. Then, through the meshing of the second bevel gear 604 with the first bevel gear 606, multiple transmission vertical shafts 603 can be driven to rotate synchronously. Finally, through the spline shaft 601, the power input shaft 6 is driven to rotate. This ensures that the running speed of multiple feeding conveyor belts 301 is consistent. Furthermore, due to the sliding fit between the spline shaft 601 and the transmission vertical shaft 603, it can be ensured that the power transmission is not affected when the spacing between each clamping conveyor mechanism 3 is adjusted within a certain range. Example 5

[0053] The difference between this embodiment and embodiment 1 is that the unloading conveyor belt 4 is inclined at a 45-degree angle, and multiple baffles 402 are evenly distributed on the outside of the unloading conveyor belt 4. The unloading transfer vehicle includes a vertically arranged lifting conveyor belt 5. An inclined guide plate 403 is provided between the unloading conveyor belt 4 and the lifting conveyor belt 5. The cut short pipes fall onto the unloading conveyor belt 4 and can stay above the baffles 402, so that they are transported one by one to the top of the inclined guide plate 403 by the unloading conveyor belt 4.

[0054] The inclined guide plate 403 is equipped with a material sensor. The lifting conveyor belt 5 is equipped with multiple sets of pipe lifting components 506 on the side close to the unloading conveyor belt 4. The lifting component 506 is equipped with a recess 507 to accommodate the pipe. After the cut short pipe falls onto the inclined guide plate 403, it stays in the recess 507. When the material sensor detects that there is material on the inclined guide plate 403, the unloading conveyor belt 4 stops running to prevent the pipe from accumulating.

[0055] The inclined guide plate 403 has the same bending arc as the recessed portion 507, and the inclined guide plate 403 has multiple through holes 404, so that the lifting member 506 can move upward and pass through the through holes 404.

[0056] When the lifting conveyor belt 5 is running, it can drive the lifting member 506 to move upward. When the lifting member 506 passes through the inclined guide plate 403 from the through port 404, it can lift the pipe and the pipe stays in the recess 507. Multiple cut pipes can be lifted upward in sequence on the lifting conveyor belt 5, so that multiple pipes can be automatically transferred and stored at one time, which is convenient for the centralized transfer of pipes.

[0057] The lifting conveyor belt 5 is installed on the lifting base 503. The lower part of the lifting base 503 is provided with a movable base 501. The four corners of the bottom of the movable base 501 are all equipped with casters 502. The lifting base 503 and the movable base 501 are connected by a telescopic guide rod 508. The bottom of the lifting base 503 is fixed with a hydraulic cylinder 509. The output shaft of the hydraulic cylinder 509 is fixed with the movable base 501. The top of the lifting base 503 is located on the side of the lifting conveyor belt 5 away from the unloading conveyor belt 4 and is fixed with an inclined bracket 504. A gripping rod 505 is installed on the inclined bracket 504 and the outside of the gripping rod 505 is provided with an anti-slip rubber sleeve.

[0058] The pipe fittings can be easily moved by the staff holding the handle 505. The height of the lifting conveyor belt 5 can be adjusted by the extension and retraction of the hydraulic cylinder 509. This allows for precise alignment with the different heights of the unloading conveyor belt 4, subsequent processing equipment, or storage shelves, avoiding pipe falling during handling due to height differences or requiring secondary manual handling, and improving the continuity of the automated process.
