Description

Technical Field

[0002] A hydrogen pipeline is a pipeline system specifically used to transport hydrogen. Its design and functions revolve around the physical and chemical properties of hydrogen. It is a key infrastructure for achieving large-scale, long-distance transportation in the hydrogen energy industry chain. A hydrogen pipeline is a transportation network composed of pipes, fittings, valves, compressor stations, and monitoring systems. It is driven by pressure to transport hydrogen from the production end to the consumption end. The segmented cutting device for hydrogen pipeline production is a device used to cut long sections of hydrogen pipelines into short pipes of specific lengths.

[0003] Currently, stainless steel is the main material of hydrogen pipelines. In the process of producing and processing long-distance hydrogen pipelines, the diameter of the pipeline is mostly In order to facilitate the subsequent transportation of pipelines, it is necessary to evenly divide the longer pipelines into small sections of equal distance by cutting. In the process of cutting such pipelines, abrasive cutting machines are often used to cut the pipelines. In order to ensure the quality of the pipelines after cutting, after all the pipelines are cut, the staff needs to centrally transport the cut pipelines to the grinding equipment for grinding. Centralized transportation requires waiting for all pipelines to be cut before they can be uniformly transferred from the cutting equipment. As a result, the next pipeline to be cut needs to wait for the previous pipeline to be completely cut before it can be cut, which increases the pipeline cutting time in the production workshop, thereby increasing the overall production cycle of the hydrogen pipeline.

[0036] In this embodiment, during the hydrogen pipeline processing, when the stainless steel pipeline needs to be cut into sections, the pipeline to be cut is first placed on a Figure 1 The outer surface of the two trough roller supports 2 shown in the figure, wherein the inner diameter of the trough roller support 2 matches the outer diameter of the pipe, and then the first forward and reverse motor 403 can be started by the controller 406 to drive the screw rod 402 to rotate, thereby driving the gantry 405 to move back and forth along the inner wall of the two lower slide bars 401, and driving the measuring instrument 8 to move along the outer surface of the pipe. At this time, the measuring instrument 8 can be started to detect the length of the pipe, and the detected signal is transmitted to the controller 406 to analyze the center position of the pipe. Then, the first forward and reverse motor 403 can be started again to move the gantry 405 to the center position of the pipe, and the first hydraulic rod 509 can be started to extend it, driving the two The arc clamps 511 move downward until the inner walls of the two arc clamps 511 move to the two sides of the pipe respectively, and then the second forward and reverse motor 512 can be started to drive the driving tube 513 to rotate, so that the two arc clamps 511 rotate relative to each other to clamp the pipe, so that the outer surfaces of the two rotating rollers 502 contact the outer surface of the pipe.

[0037] like Figure 1 and Figure 3-10As shown, the outer surfaces of the two slides 601 are rotatably connected to the inner walls of the two rotating blocks 602, the outer surfaces of the two rotating blocks 602 are fixedly connected to the other ends of the two multi-stage telescopic rods 701, and one end of the two hollow tubes 702 is fixedly connected to the outer surfaces of the two rotating blocks 602. The inner bottom surfaces of the two slides 601 are fixedly installed with pressure-resistant frames 604, and the inner top surfaces of the two pressure-resistant frames 604 are both provided with stepper motors 605. The output ends of the two stepper motors 605 are fixedly connected to the output tubes 60 6. The bottom ends of the two output tubes 606 are movably embedded in the interior of the pressure-resistant frame 604. The outer surfaces of the two output tubes 606 are fixedly sleeved with driving gears 607. The outer surfaces of the two driving gears 607 are respectively meshed with the outer surfaces of the two driven gears 603. The bottoms of the two slides 601 are respectively provided with electric telescopic rods 608 near the center. The bottoms of the two electric telescopic rods 608 are fixed with mounting plates 609. The bottoms of the two mounting plates 609 are respectively coupled with the outer surfaces of the two cutting machines 610.

[0038] In this embodiment, after the center position of the pipeline moves to the specified position, the second hydraulic rod 514 can be started again to shorten it slightly, so that the mutual squeezing force between the positioning plate 515 and the pipeline is reduced, thereby reducing the resistance to the subsequent rotation of the pipeline. Then the servo motor 505 can be started to drive the rotating shaft 506 to rotate, thereby driving the small gear ring 507 to rotate, thereby rotating the large gear ring 503, and then driving the fixing frame 407 to rotate 90°, thereby causing the two cutting machines 610 and the two clamping members 710 to rotate 90° and move to a position parallel to the pipeline respectively. Then the second driving motor 410 can be started to drive the bidirectional threaded rod 409 to rotate, thereby driving the two rotating blocks 602 to move in directions away from each other along the outer surfaces of the bidirectional threaded rod 409. Until the two cutters 610 are at the same distance from the two ends of the pipe as the length required to be cut, the second drive motor 410 can be turned off, and then the two electric telescopic rods 608 can be started to extend, driving the two cutters 610 to move downward to a position where the outer surface contacts the outer surface of the pipe, and then the two third drive motors 517 can be started by the controller 406 to drive the two transmission shafts 508 to rotate, thereby driving the two rotating rollers 502 to rotate in the same direction, so that the pipe rotates in place under the friction of the two rotating rollers 502, and then the two cutters 610 can be started to cut the rotating pipe, thereby realizing the segmentation of the pipe. The design of the two synchronously moving cutters 610 improves the efficiency of pipe cutting. Figure 8 As shown, the cutting machine 610 relies on a high-speed rotating cutting grinding wheel, using its hardness and kinetic energy generated by movement to rub and cut the pipe surface, gradually removing the pipe wall material to separate the pipe. The motor drives the grinding wheel to rotate at high speed, grinding the pipe wall to achieve cutting.

[0039] like Figure 1 and Figures 8-12 As shown, a segmented cutting device for hydrogen pipeline production includes an operating base plate 1, a grinding device body 3, and a sliding assembly 4 for moving the cutting piece to the center of the pipeline. Two grooved roller brackets 2 for supporting the pipeline are set near the center of the top of the operating base plate 1. A positioning assembly 5 for fixing the pipeline is set near the center inside the sliding assembly 4. Two cutting assemblies 6 for segmenting the pipeline are set inside the sliding assembly 4. Both cutting assemblies 6 include a slide plate 601 and a rotating block 602. The bottom of the two rotating blocks 602 are fixed with driven gears. Wheel 603, a cutting machine 610 is provided at the bottom of the two slides 601, a synchronous transfer assembly 7 is provided on the outer surface of the two rotating blocks 602, and the two synchronous transfer assemblies 7 include a screw 703 for extension and contraction, one end of each of the two screws 703 is fixed with a first bevel gear 711, the outer surfaces of the two first bevel gears 711 are meshed and connected with a second bevel gear 708, and the bottoms of the two second bevel gears 708 are provided with a clamping piece 710 for clamping the pipe, and the two clamping pieces 710 respectively clamp the cut pipe and then pass through the rotation of the first bevel gear 711. The rotation and extension of the screw 703 rotate the pipe and move it to the interior of the grinding equipment body 3 for grinding. The two synchronous transfer components 7 also include two multi-stage telescopic rods 701. Each adjacent two multi-stage telescopic rods 701 form a group. One end of each group of multi-stage telescopic rods 701 is fixed with a moving block 704. The outer surfaces of the two screws 703 are threaded with a hollow tube 702. The tops of the two moving blocks 704 are fixedly installed with positioning brackets 705 near one side edge. The inner walls of the two positioning brackets 705 are fixed with first Driving motor 706, the output ends of the two first driving motors 706 are fixed with connecting shafts 707, the bottom ends of the two connecting shafts 707 are provided with reducers 712, the output ends of the two reducers 712 are coupled with connecting rods 713, and the bottoms of the two connecting rods 713 are provided with electric push rods 709. One ends of the two screw rods 703 are movable and pass through the interior of the two moving blocks 704 respectively. The two first bevel gears 711 are respectively provided in the interior of the two moving blocks 704, and the bottom ends of the two electric push rods 709 are respectively fixedly connected to the tops of the two clamping members 710.

[0040] In this embodiment, before cutting the pipe, in order to achieve the synchronous transfer of the cut pipe, when the two electric telescopic rods 608 respectively move the two cutters 610 to the position of contacting the outer surface of the pipe, the controller 406 can respectively start the two stepping motors 605 to drive the two output tubes 606 to rotate, and then respectively drive the two driving gears 607 to rotate, thereby causing the two driven gears 603 to rotate, and then causing the two rotating blocks 602 to respectively move along the following direction. Figure 10The cylinder in the center of the slide 601 shown rotates 180 degrees, so that the two clamping members 710 are respectively moved to the top of the pipe, and the clamps in the two clamping members 710 are respectively parallel to the pipe. Then, the two first drive motors 706 can be started by the controller 406 to drive the two connecting shafts 707 to rotate. After the speed is adjusted by the reducer 712, the connecting rod 713 drives the electric push rod 709 to rotate and then drives the clamping member 710 to rotate. At the same time, the rotation of the connecting shaft 707 also drives the second bevel gear 708 to rotate, thereby rotating the two first bevel gears 711, thereby rotating the two screws 703, and then the two screws 703 are respectively moved to the outside of the two hollow tubes 702. Since the two moving blocks 704 are respectively limited by the multi-stage telescopic rod 701, when the screw 703 moves outward, the moving block 704 is driven to move in the direction away from the rotating block 602, so that the multi-stage telescopic rod 701 is extended, thereby driving the two clamping members 710 to move forward. When the two clamping members 710 move to the center position of the pipe cutting part, the connecting rod 713 just drives the clamping members 710 to rotate 90 degrees, until the two clamps correspond to the two sides of the pipe respectively. Then, the two electric push rods 709 can be started to extend, driving the two clamping members 710 downward, so that the clamps in the two clamping members 710 are respectively on both sides of the pipe. Then, the pipe can be clamped by starting the clamping members 710. Figure 12 The pipe extrusion plate shown squeezes and fixes the pipe. When the pipe cutting is completed, the two first drive motors 706 can be started again to drive the cut pipe to move forward a certain distance and rotate. When the cut pipe rotates 90 degrees, the pipe is just moved to the grinding device body 3. Figure 2 The top of the pipe positioning bin shown in the figure can open the two clamping members 710, so that the two cut pipes are placed in the corresponding grinding device body 3 for grinding. The working principles of the two clamping members 710 are the same as the working principles of the clamping devices corresponding to the arc clamp 511 in the above-mentioned positioning assembly 5. No more introduction is given here. The working principle of the grinding device body 3 is: the driving device drives the main shaft to rotate through the belt, and the grinding belt wheel is installed on the main shaft. The two sides of the pipe are Figure 2The positioning device shown is fixed to ensure that it does not shake during grinding. The high-speed rotating grinding wheel contacts the end face of the pipe, and the burrs and oxide scale are removed by the cutting action of the abrasive to achieve pipe grinding. When the cut pipe is placed inside the grinding device body 3 for grinding, the first drive motor 706 can be started in reverse to drive the two clamping members 710 to reset, and the second drive motor 410 drives the clamping members 710 and the cutter 610 to move toward the center of the pipe by a distance corresponding to the pipe cutting length, and continue to cut and transfer the pipe for grinding. Through the action of the cutting component 6 and the synchronous transfer component 7, the pipe can be synchronously transferred and polished during the segmented cutting process, thereby effectively reducing the pipe transportation time after the pipe cutting is completed, and preventing the pipe from being uniformly removed from the cutting equipment and then transported after the pipe cutting is completed, which increases the waiting time for the next pipe cutting. The problem that the process of uniform transfer of the pipes in the workshop after complete cutting in the prior art causes the waiting time for the next pipe cutting to increase the overall production cycle of the hydrogen energy pipeline is solved.

[0041] The use method and working principle of this device: During the hydrogen pipeline processing, when it is necessary to cut the stainless steel pipeline into sections, first place the pipeline to be cut in the following way: Figure 1 The outer surface of the two trough roller supports 2 shown, wherein the inner diameter of the trough roller support 2 matches the outer diameter of the pipeline, and then the first forward and reverse motor 403 can be started by the controller 406 to drive the screw rod 402 to rotate, thereby driving the gantry 405 to move back and forth along the inner wall of the two lower slide bars 401, and driving the measuring instrument 8 to move along the outer surface of the pipeline. At this time, the measuring instrument 8 can be started to detect the length of the pipeline, and the detected signal is transmitted to the controller 406 to analyze the center position of the pipeline. The measuring instrument 8 emits a high-speed scanning beam through a laser transmitter to cover the top of the pipeline. The time difference when the pipeline blocks the laser corresponds to the pipeline length: Length formula: , is the laser scanning speed, The sensor receives the reflected signal, converts it into length through the algorithm, and outputs the data in real time. Then, the first forward and reverse motor 403 is started again to move the gantry 405 to the center of the pipeline, and the first hydraulic rod 509 is started to extend, driving the two arc clamps 511 to move downward until the inner walls of the two arc clamps 511 move to the two sides of the pipeline respectively. Then, the second forward and reverse motor 512 is started to drive the driving tube 513 to rotate, thereby causing the two arc clamps 511 to rotate relative to each other. Figure 7As shown, the two arc clamps 511 are in mortise-and-tenon contact. When one of the arc clamps 511 rotates, it drives the other arc clamp 511 to rotate in the opposite direction to clamp the pipe, thereby making the outer surfaces of the two rotating rollers 502 contact the outer surface of the pipe. At the same time, the second hydraulic rod 514 is started to extend, driving the positioning plate 515 to move downward, pressing the pipe to achieve clamping of the pipe. The first forward and reverse motor 403 can be started to make the two arc clamps 511 move the center position of the pipe to the center position of the distance between the two grooved roller brackets 2. The second hydraulic rod 514 is started again to shorten it slightly, so that the mutual squeezing force between the positioning plate 515 and the pipe is reduced, thereby reducing the resistance to subsequent rotation of the pipe. Then the servo motor 505 can be started to drive the rotating shaft 506 to rotate, thereby driving the small gear ring 507 to rotate, thereby causing the large gear ring 503 to rotate, and then driving the fixed frame 407 to rotate 90°, thereby The two cutters 610 and the two clamping members 710 are rotated 90 degrees and moved to a position parallel to the pipe. Then the second drive motor 410 can be started to drive the bidirectional threaded rod 409 to rotate, thereby driving the two rotating blocks 602 to move in directions away from the outer surfaces of the bidirectional threaded rod 409 respectively, until the two cutters 610 are at the same distance from the two ends of the pipe as the length to be cut. Then the second drive motor 410 can be turned off, and then the two electric telescopic rods 608 can be started to extend, driving the two cutters 610 to move downward to a position where the outer surface contacts the outer surface of the pipe. Then the two third drive motors 517 can be started by the controller 406 to drive the two transmission shafts 508 to rotate, thereby driving the two rotating rollers 502 to rotate in the same direction, so that the pipe rotates in place under the friction of the two rotating rollers 502. Then the two cutters 610 can be started to cut the rotating pipe, wherein, Figure 8 As shown, the cutting machine 610 relies on a high-speed rotating cutting grinding wheel, and utilizes its hardness and kinetic energy generated by movement to rub and cut with the surface of the pipe, gradually removing the pipe wall material and separating the pipe. The motor drives the grinding wheel to rotate at high speed, grinding the pipe wall to achieve cutting. Before cutting the pipe, in order to achieve synchronous transfer of the cut pipe, when the two electric telescopic rods 608 respectively move the two cutting machines 610 to a position in contact with the outer surface of the pipe, the controller 406 can be used to start the two stepping motors 605 respectively, driving the two output pipes 606 to rotate, and then respectively driving the two driving gears 607 to rotate, so that the two driven gears 603 rotate, and then the two rotating blocks 602 respectively move along as shown in FIG. Figure 10The cylinder in the center of the slide 601 shown rotates 180 degrees, so that the two clamping members 710 are respectively moved to the top of the pipe, and the clamps in the two clamping members 710 are respectively parallel to the pipe. Then, the two first drive motors 706 can be started by the controller 406 to drive the two connecting shafts 707 to rotate. After the speed is adjusted by the reducer 712, the connecting rod 713 drives the electric push rod 709 to rotate and then drives the clamping member 710 to rotate. At the same time, the rotation of the connecting shaft 707 also drives the second bevel gear 708 to rotate, thereby rotating the two first bevel gears 711, thereby rotating the two screws 703, and then the two screws 703 are respectively moved to the outside of the two hollow tubes 702. Since the two moving blocks 704 are respectively limited by the multi-stage telescopic rod 701, when the screw 703 moves outward, the moving block 704 is driven to move in the direction away from the rotating block 602, so that the multi-stage telescopic rod 701 is extended, thereby driving the two clamping members 710 to move forward. When the two clamping members 710 move to the center position of the pipe cutting part, the connecting rod 713 just drives the clamping members 710 to rotate 90 degrees, until the two clamps correspond to the two sides of the pipe respectively. Then, the two electric push rods 709 can be started to extend, driving the two clamping members 710 downward, so that the clamps in the two clamping members 710 are respectively on both sides of the pipe. Then, the pipe can be clamped by starting the clamping members 710. Figure 12 The pipe extrusion plate shown squeezes and fixes the pipe. When the pipe cutting is completed, the two first drive motors 706 can be started again to drive the cut pipe to move forward a certain distance and rotate. When the cut pipe rotates 90 degrees, the pipe is just moved to the grinding device body 3. Figure 2 The top of the pipe positioning bin shown in the figure can open the two clamping members 710, so that the two cut pipes are placed in the corresponding grinding device body 3 for grinding. The working principles of the two clamping members 710 are the same as the working principles of the clamping devices corresponding to the arc clamp 511 in the above-mentioned positioning assembly 5. No more introduction is given here. The driving device in the grinding device body 3 drives the main shaft to rotate through the belt, and the grinding belt wheel is installed on the main shaft. The two sides of the pipe are Figure 2 The positioning device shown is fixed to ensure that it does not shake during grinding. The high-speed rotating grinding wheel contacts the end face of the pipe, and the burrs and oxide scale are removed by the cutting action of the abrasive to achieve pipe grinding. When the cut pipe is placed inside the grinding device body 3 for grinding, the first drive motor 706 can be started in reverse to drive the two clamping members 710 to reset, and the clamping members 710 and the cutting machine 610 are driven by the second drive motor 410 to move toward the center of the pipe by a distance corresponding to the pipe cutting length, and the pipe is continued to be cut and transferred for grinding.
