Description

Technical Field

[0001] This invention belongs to the field of pipeline welding, specifically relating to a welding device for processing pipelines in high slope construction of water conservancy projects. Background Technology

[0002] Traditional pipeline welding equipment used in high-slope construction of water conservancy projects lacks dedicated docking benchmarks and synchronous clamping structures. After pipeline placement, issues such as axial misalignment, port misalignment, and uneven weld gaps easily arise. Manual alignment is inefficient, and uneven clamping forces can cause pipeline deformation, resulting in poor welding accuracy and weld quality. Furthermore, the limited space on high slopes makes the existing equipment cumbersome to clamp and align, failing to meet the demands of efficient on-site welding and impacting the overall construction progress of pipeline welding.

[0003] Patent CN221735297U discloses a welding device for pipe processing, including a support, a positioning mechanism, a rotating mechanism, and a rust-removing welding mechanism. The positioning mechanism includes a drive motor, a fixed sleeve, a driving gear, a driven gear, a positioning plate, and a tensioning sleeve. The rotating mechanism includes a gear transmission mechanism and a transmission mechanism. The gear transmission mechanism includes an internal gear sleeve, a pinion, an external gear sleeve, and a support frame. The transmission mechanism includes a transmission motor, a transmission gear, and a transmission belt. The rust-removing welding mechanism includes a grinding mechanism and an angle adjustment mechanism. The grinding mechanism includes a bearing plate, a positioning rod, a first spring, a grinding block, a screw, and a micro motor. The angle adjustment mechanism includes a welding torch and an electric push rod. With the cooperation of the positioning mechanism, the rotating mechanism, and the rust-removing welding mechanism, this patent can achieve functions such as manual welding, precise pipe fixing, and automatic rust removal and grinding.

[0004] However, during the use of the above-mentioned device, it is difficult to center and align the pipe during the process of fixing and clamping the pipe, so that the welding of the pipe is in the center area of ​​the welding. This makes it easy for welding errors to occur during the pipe welding process, which in turn affects the accuracy and quality of subsequent pipe welding. Summary of the Invention

[0005] The purpose of this invention is to provide a welding device for processing pipelines in high slope construction of water conservancy projects, so as to solve the problem that the pipeline is easily misaligned and not clamped and fixed during the welding process, resulting in reduced welding accuracy.

[0006] To achieve the above objectives, the present invention provides a welding device for pipeline processing in high slope construction of water conservancy projects, comprising: a base frame, a three-dimensional slide rail mounted on the base frame, a multi-angle welding device mounted on the moving end of the three-dimensional slide rail, an electric slide rail mounted on the base frame, a self-adjusting roller frame mounted on the moving end of the electric slide rail, a cylinder mounted on the base frame, a fixed plate fixedly connected to the telescopic end of the cylinder, a positioning arc plate fixedly connected to the top of the fixed plate, a clamping mechanism for pipe clamping provided on the inner wall of the self-adjusting roller frame, a collection mechanism for welding slag collection provided on the circumferential surface of the positioning arc plate, an electric roller mounted on the self-adjusting roller frame, an electric gripper mounted on the top of the positioning arc plate, and a vertical frame mounted on the base frame. The electric gripper can clamp the pipeline used in high slope construction, while the positioning arc plate can align the pipeline workpiece. At this time, the multi-angle welding equipment can weld two pipelines, which can directly improve the welding quality between the pipelines. The inner wall of the vertical frame is slidably connected to a sliding rod, the right side of the positioning arc plate is rotatably connected to a connecting rod, the inner wall of the sliding rod is fixedly connected to a fixing column, the right side of the sliding rod is fixedly connected to an elastic telescopic rod, the telescopic end of the elastic telescopic rod is fixedly connected to a handrail, the left side of the handrail is fixedly connected to a locking column, and the inner wall of the sliding rod is movably connected to an alignment slide plate. The high slope construction pipeline is placed on the electric roller to avoid the angle difference between the two pipelines, which would affect the welding accuracy and improve the welding efficiency of the device.

[0007] In one possible implementation, the self-adjusting roller frame contacts the base frame, and the alignment slide plate contacts the high slope construction pipeline. The alignment slide plate serves as the welding reference center, forming a weld seam. This allows the ends of the two pipelines to fit snugly against the alignment slide plate, achieving coaxial and end-face docking. This avoids problems such as pipeline eccentricity, misalignment, and uneven end faces, ensuring the weld seam is always in a preset standard docking position. This guarantees the accuracy of weld seam alignment from the source, improves welding quality, provides a precise docking reference, and ensures the accuracy of pipeline weld seam alignment. The connecting rod is rotatably connected to the circumferential surface of the fixed column, and there is an angular difference between the connecting rod and the fixed column, unifying the weld seam gap and ensuring welding consistency. It can serve as a precise reference for the gap of the pipeline butt weld, ensuring that the two pipelines form a uniform and standard weld seam gap after contacting the plate, avoiding defects such as incomplete fusion, burn-through, and slag inclusion caused by excessively large, small, or uneven gaps.

[0008] In one possible implementation, the locking pin contacts the sliding rod and the alignment slide plate, and the locking pin is used to limit the alignment slide plate so that the welding side of the pipe contacts the alignment slide plate. When the two pipes contact the alignment slide plate respectively, the alignment slide plate can form a corresponding weld. With the alignment slide plate as the welding center, the movement of the positioning arc plate during the upward process will drive the connecting rod to rise.

[0009] In one possible implementation, the clamping mechanism includes a motor fixedly connected to the front of a self-adjusting roller frame. A reciprocating lead screw is rotatably connected to the inner wall of the self-adjusting roller frame, and a guide column is fixedly connected to the inner wall of the self-adjusting roller frame. A moving rod is movably connected to the circumferential surface of the reciprocating lead screw. An electric arc slide is fixedly connected to the front of the moving rod. A second elastic telescopic rod is fixedly connected to the moving end of the electric arc slide. A clamping plate is fixedly connected to the telescopic end of the second elastic telescopic rod. A first protrusion is fixedly connected to the arc surface of the clamping plate, and a second protrusion is fixedly connected to the inner wall of the electric arc slide. During the movement of the first protrusion, the first protrusion will drive the clamping plate to move. During the movement of the clamping plate, the clamping plate will contact a part of the pipe and fix and clamp the pipe, which can ensure the stability of the pipe during the welding process and avoid vibration during the welding process, thereby affecting the welding accuracy and quality.

[0010] In one possible implementation, the clamping mechanism further includes a connector fixedly connected to the circumferential surface of the positioning arc plate. A collecting arc box is fixedly connected to the top of the connector. The collecting arc box is located close to the welding area and directly below the welding area. In this case, during the welding process of the multi-angle welding equipment, the welding slag and other debris generated can fall naturally into the collecting arc box, preventing the welding slag and other debris from being scattered on the relevant equipment, thereby affecting the welding operation, avoiding jamming of the device during the welding process, and improving the welding efficiency of the device.

[0011] In one possible implementation, the movable rod is slidably connected to the circumferential surface of the guide post, and the guide post is used to provide movement limit guidance for the movable rod. The second protrusion is located on the movement trajectory of the first protrusion, and the second protrusion is used to squeeze and push the first protrusion to move. The movement of the electric arc slide rail will drive the second elastic telescopic rod to move laterally. The second elastic telescopic rod will drive the clamping plate to move, and the clamping plate will drive the first protrusion to move. When the clamping plate moves to the appropriate area, the electric arc slide rail will start and drive the second elastic telescopic rod to move on its own inner wall.

[0012] In one possible implementation, the collection mechanism includes a rotating column rotatably connected to the inner wall of the collection arc box. A connecting roller is fixedly connected to the circumferential surface of the rotating column, and a brush plate is fixedly connected to the circumferential surface of the rotating column. The rotation of the rotating column will drive the brush plate to rotate. During the rotation process, the brush plate can clean the debris and welding slag remaining at the weld seam between the pipes, thereby improving the quality and effect of pipe welding.

[0013] In one possible implementation, the collecting mechanism further includes a mounting frame fixedly connected to the top of the collecting arc box. An elastic telescopic rod three is fixedly connected to the inner wall of the mounting frame, and a mounting plate is fixedly connected to the telescopic end of the elastic telescopic rod three. A contact roller is rotatably connected to the inner wall of the mounting plate, and a numerical column is fixedly connected to the inner wall of the mounting plate. A laser displacement device is fixedly connected to the inner wall of the mounting frame. During the movement of the numerical column, the laser displacement device can transmit abnormal phenomena to an external control terminal based on the movement distance signal of the numerical column. This allows for preliminary observation and statistical analysis of the welding quality, directly improving the welding quality and effectiveness of the device.

[0014] In one possible implementation, the high slope construction pipeline workpiece is located on the motion trajectory of the connecting roller, the high slope construction pipeline is located on the motion trajectory of the brush plate, and the high slope construction pipeline is located on the motion trajectory of the contact roller. The numerical column is in contact with the mounting frame, the collecting arc box will drive the mounting frame to move, the movement of the mounting frame will drive the elastic telescopic rod three to rise, the rise of the elastic telescopic rod three will drive the mounting plate to rise, and the rise of the mounting plate will drive the contact roller to rise.

[0015] A welding process for pipeline fabrication in high slope construction of water conservancy projects includes the following steps: Step 1: Before welding the high slope construction pipes, the operator can use an external transportation mechanism to place the two high slope construction pipes to be welded on top of the electric rollers in sequence. The two electric rollers can be moved by the CNC of the self-adjusting roller frame, and the distance between the two electric rollers can be controlled according to the size of the high slope construction pipes. Step 2: Ensure that the pipeline for high slope construction is positioned on the two electric rollers. After the preparation is completed, the cylinder will start, and the extension end of the cylinder will drive the fixed plate to rise. The movement of the fixed plate will drive the positioning arc plate to move. Step 3: The movement of the positioning arc plate will drive the electric gripper to rise synchronously. After the positioning arc plate moves a certain distance, it will contact the high slope construction pipeline and provide support for it. After the high slope construction pipeline contacts the positioning arc plate, the electric gripper will start. Step 4: The electric gripper can clamp the pipeline for high slope construction, and the positioning arc plate can align the pipeline workpiece. At this time, the multi-angle welding equipment can weld the two pipelines, which can directly improve the welding quality between the pipelines.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1.

Improving the welding quality between pipes and avoiding angular differences between the two pipes that affect welding accuracy can enhance the welding efficiency of the device. It allows the alignment plate to serve as the welding reference center, forming a weld seam that ensures the ends of the two pipes align with the plate, achieving coaxial and end-face docking. This avoids issues such as pipe eccentricity, ensuring the weld seam is always in the preset standard docking position, improving welding quality, providing a precise docking reference, guaranteeing pipe weld seam alignment accuracy, and standardizing weld gaps. This prevents defects such as incomplete fusion, burn-through, and slag inclusions caused by excessively large, small, or uneven gaps.

Through the coordinated movement of a motor, reciprocating lead screw, guide column, moving rod, electric arc slide, elastic telescopic rod II, clamping plate, protrusion I, protrusion II, connecting parts, and arc collecting box, protrusion I moves, causing the clamping plate to move as well. During this movement, the clamping plate contacts and clamps a portion of the pipeline, ensuring the stability of the pipeline during welding and preventing vibration that could affect welding accuracy and quality. The arc collecting box is located close to and directly below the welding area. During welding, slag and other debris generated by the multi-angle welding equipment naturally fall into the arc collecting box, preventing slag and other debris from scattering on the equipment and affecting welding operations. This avoids jamming during welding and improves the welding efficiency of the device.

[0018] 3. A welding device and construction process for pipeline processing in high slope construction of water conservancy projects. Through the coordinated movement of a rotating column, connecting rollers, a brush plate, a mounting frame, an elastic telescopic rod, a mounting plate, contact rollers, a numerical column, and a laser displacement device, the rotating column rotates, causing the brush plate to rotate. During rotation, the brush plate cleans debris and welding slag from the weld seams between pipes, improving the quality and effect of pipeline welding. During the movement of the numerical column, the laser displacement device transmits abnormal phenomena to an external control terminal based on the column's movement distance signal, enabling preliminary observation and statistical analysis of the welding quality. This directly improves the welding quality and effect of the device. Attached Figure Description

Detailed Implementation

[0021] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] like Figures 1-8As shown, one embodiment of the present invention is: a welding device for processing pipelines in high slope construction of water conservancy projects, comprising: a base frame 1, a three-dimensional slide rail 2 mounted on the base frame 1, a multi-angle welding device mounted on the moving end of the three-dimensional slide rail 2, an electric slide rail 3 mounted on the base frame 1, a self-adjusting roller frame 4 mounted on the moving end of the electric slide rail 3, a cylinder 5 mounted on the base frame 1, a fixed plate 6 fixedly connected to the telescopic end of the cylinder 5, a positioning arc plate 7 fixedly connected to the top of the fixed plate 6, a clamping mechanism 8 for clamping the pipeline mounted on the inner wall of the self-adjusting roller frame 4, and a slag collector mounted on the circumferential surface of the positioning arc plate 7. The structure includes a self-adjusting roller frame 4 with an electric roller 10, an electric gripper 11 on the top of the positioning arc plate 7, a vertical frame 12 on the base frame 1, a sliding rod 13 slidably connected to the inner wall of the vertical frame 12, a connecting rod 14 rotatably connected to the right side of the positioning arc plate 7, a fixed column 15 fixedly connected to the inner wall of the sliding rod 13, an elastic telescopic rod 16 fixedly connected to the right side of the sliding rod 13, a handrail 17 fixedly connected to the telescopic end of the elastic telescopic rod 16, a locking column 18 fixedly connected to the left side of the handrail 17, an alignment slide plate 19 movably connected to the inner wall of the sliding rod 13, and a high slope construction pipe placed on the electric roller 10. Before welding the high slope construction pipes, the operator can use an external transport mechanism to place the two high slope construction pipes to be welded sequentially above the electric rollers 10. The two electric rollers 10 can be moved by the CNC of the self-adjusting roller frame 4. The distance between the two electric rollers 10 is controlled according to the size of the high slope construction pipes to ensure that the high slope construction pipes are positioned on the two electric rollers 10. After the preparation is completed, the cylinder 5 will be activated. The extension end of the cylinder 5 will drive the fixed plate 6 to rise. The movement of the fixed plate 6 will drive the positioning arc plate 7 to move. The movement of the positioning arc plate 7 will... The electric gripper 11 is driven to rise synchronously. After the positioning arc plate 7 moves a certain distance, it will contact the high slope construction pipeline and provide support for it. After the high slope construction pipeline contacts the positioning arc plate 7, the electric gripper 11 will start and clamp the high slope construction pipeline. At the same time, the positioning arc plate 7 can align the pipeline workpiece. At this time, the multi-angle welding equipment can perform welding operations on the two pipelines, which can directly improve the welding quality between the pipelines, avoid the angle difference between the two pipelines, and affect the welding accuracy, thus improving the welding efficiency of the device. The self-adjusting roller frame 4 contacts the base frame 1, the alignment plate 19 contacts the high slope construction pipeline, the connecting rod 14 is rotatably connected to the circumferential surface of the fixed column 15, and there is an angle difference between the connecting rod 14 and the fixed column 15. The locking column 18 contacts the sliding rod 13, the locking column 18 contacts the alignment plate 19, and the locking column 18 is used to limit the alignment plate 19. Before welding, during the placement of the pipes, two pipes need to be placed sequentially on the electric roller 10, and pushed by an external pushing device to make the welding side of the pipes contact the alignment plate 19. After the two pipes contact the alignment plate 19, the alignment plate 19 can form corresponding welds, with the alignment plate 19 as the welding center. During the rising process of the positioning arc plate 7, the movement of the positioning arc plate 7 will drive the connecting rod 14 to rise. During the rising process, there will be an angle difference between the connecting rod 14 and the fixed column 15. At this time, the connecting rod 14 will self-adjust its angle during the rising process. During the angle adjustment process, the connecting rod 14 will synchronously drive the fixed column 15 to move. During the movement of the fixed column 15, the fixed column 15 will drive the sliding rod 13 to move. The sliding rod 13 will slide in the groove of the vertical frame 12. The movement of the sliding rod 13 will drive the elastic telescopic rod 16 to move. The movement of the elastic telescopic rod 16 will cause the handrail 17 to move, which in turn will cause the locking post 18 to move, which in turn will cause the alignment slide plate 19 to move. After moving a certain distance, the alignment slide plate 19 will no longer be in contact with the weld between the two pipes. Through the above operations, the alignment slide plate 19 can be used as the welding reference center to form a weld, so that the ends of the two pipes can fit against the alignment slide plate 19 to achieve coaxial and same-end face docking. This avoids problems such as pipe eccentricity, misalignment, and uneven end faces, and keeps the weld in the preset standard docking position. This ensures the accuracy of weld alignment from the source, improves the quality of weld formation, provides a precise docking reference, ensures the alignment accuracy of pipe welds, unifies the weld gap, and ensures welding consistency. It can be used as a precise reference for the gap of pipe butt welds, so that the two pipes form a uniform and standard weld gap after contacting the plate, avoiding defects such as incomplete fusion, burn-through, and slag inclusion caused by excessively large, small, or uneven gaps. Overall working principle: After the pipeline in high slope construction comes into contact with the positioning arc plate 7, the electric gripper 11 will activate, clamping the pipeline. Simultaneously, the positioning arc plate 7 aligns the pipeline. At this point, the multi-angle welding equipment can weld the two pipelines, directly improving the welding quality and preventing angle differences between them from affecting welding accuracy. This increases the welding efficiency of the device. The alignment slide plate 19 will not contact the weld seam between the two pipelines. Through the above operations, the alignment slide plate 19 serves as the welding reference center, forming... The weld seam allows the ends of two pipes to fit together and align with the sliding plate 19, achieving coaxial and end-face docking. This avoids problems such as pipe eccentricity, misalignment, and uneven end faces, ensuring that the weld seam is always in the preset standard docking position. This guarantees the accuracy of weld seam alignment from the source, improves the quality of weld formation, provides a precise docking benchmark, ensures the alignment accuracy of pipe weld seams, unifies the weld seam gap, and ensures welding consistency. It can serve as a precise reference for the gap of pipe butt weld seams, ensuring that a uniform and standard weld seam gap is formed after the two pipes contact the plate, avoiding defects such as incomplete fusion, burn-through, and slag inclusion caused by excessively large, small, or uneven gaps.

[0023] like Figures 1-8 As shown, in another embodiment of the present invention based on the above embodiments, the clamping mechanism 8 includes a motor 801, which is fixedly connected to the front of the self-adjusting roller frame 4. A reciprocating screw 802 is rotatably connected to the inner wall of the self-adjusting roller frame 4, and a guide post 803 is fixedly connected to the inner wall of the self-adjusting roller frame 4. A moving rod 804 is movably connected to the circumferential surface of the reciprocating screw 802. An electric arc slide rail 805 is fixedly connected to the front of the moving rod 804. An elastic telescopic rod 806 is fixedly connected to the moving end of the electric arc slide rail 805. An arc clamping plate 807 is fixedly connected to the telescopic end of the elastic telescopic rod 806. A protrusion 808 is fixedly connected to the arc surface of the arc clamping plate 807. A protrusion 809 is fixedly connected to the inner wall of the electric arc slide rail 805. When the device is in use, motor 801 starts, and the output of motor 801 drives reciprocating screw 802 to rotate. During the rotation of reciprocating screw 802, it drives moving rod 804 to rotate. However, moving rod 804 is guided by guide post 803. At this time, during the rotation of reciprocating screw 802, moving rod 804 can only move laterally through the reciprocating groove on the surface of reciprocating screw 802. The lateral movement of moving rod 804 drives electric arc slide rail 805 to move. The movement of electric arc slide rail 805 drives elastic telescopic rod 806 to move laterally. Elastic telescopic rod 806 drives arc clamping plate 807 to move. Arc clamping plate 807 drives protrusion 808 to move. When arc clamping plate 807 moves to the appropriate area, at this time... The electric arc slide 805 will start and drive the elastic telescopic rod 806 to move on its inner wall. The movement of the elastic telescopic rod 806 will drive the clamping plate 807 to move. The movement of the clamping plate 807 will drive the protrusion 808 to move. After moving a certain distance, the arc surface of the protrusion 808 will contact the protrusion 809. At this time, the protrusion 809 will push the protrusion 808 to move by its own arc surface. During the movement, the protrusion 808 will drive the clamping plate 807 to move. During the movement, the clamping plate 807 will contact a part of the pipe and fix and clamp the pipe, which can ensure the stability of the pipe during the welding process and avoid the pipe from shaking during the welding process, thus affecting the welding accuracy and quality. The clamping mechanism 8 also includes a connector 810, which is fixedly connected to the circumferential surface of the positioning arc plate 7. A collecting arc box 811 is fixedly connected to the top of the connector 810. The moving rod 804 is slidably connected to the circumferential surface of the guide post 803, and the guide post 803 is used to provide movement limit guidance for the moving rod 804. The second protrusion 809 is located on the movement trajectory of the first protrusion 808, and the second protrusion 809 is used to squeeze and push the first protrusion 808 to move. During the welding process, the upward movement of the positioning arc plate 7 will drive the connecting piece 810 to move upward synchronously. The upward movement of the connecting piece 810 will drive the collecting arc box 811 to rise. After rising a certain distance, the collecting arc box 811 can approach the welding area and be located directly below the welding area. At this time, during the welding process of the multi-angle welding equipment, the welding slag and other debris generated can fall naturally into the collecting arc box 811, preventing the welding slag and other debris from being scattered on the relevant equipment, thereby affecting the welding operation, avoiding jamming of the device during the welding process, and improving the welding efficiency of the device. The collection mechanism 9 includes a rotating column 901, which is rotatably connected to the inner wall of the collection arc box 811. A connecting roller 902 is fixedly connected to the circumferential surface of the rotating column 901, and a brush plate 903 is fixedly connected to the circumferential surface of the rotating column 901. During use, as the arc collecting box 811 rises, it drives the rotating column 901 to rise synchronously. The rising of the rotating column 901 moves the connecting roller 902, which in turn moves the brush plate 903. After moving a certain distance, the connecting roller 902 comes into contact with the pipe. Once a portion of the pipe is welded, one of the two electric rollers 10 on either side rotates, causing the pipe to rotate stably. During this rotation, the connecting roller 902 generates friction due to contact with the pipe, causing it to rotate around itself. This rotation drives the rotating column 901, which in turn rotates the brush plate 903. As the brush plate 903 rotates, it cleans away debris and slag from the weld seam between the pipes, improving the quality and effectiveness of the pipe welding. The collection mechanism 9 also includes a mounting frame 904, which is fixedly connected to the top of the collection arc box 811. An elastic telescopic rod 905 is fixedly connected to the inner wall of the mounting frame 904. An installation plate 906 is fixedly connected to the telescopic end of the elastic telescopic rod 905. A contact roller 907 is rotatably connected to the inner wall of the installation plate 906. A numerical column 908 is fixedly connected to the inner wall of the installation plate 906. A laser displacement device 909 is fixedly connected to the inner wall of the mounting frame 904. The high slope construction pipeline workpiece is located on the movement trajectory of the connecting roller 902, the high slope construction pipeline is located on the movement trajectory of the brush plate 903, and the high slope construction pipeline is located on the movement trajectory of the contact roller 907. The numerical column 908 is in contact with the mounting frame 904. During the upward movement of the arc collecting box 811, it drives the mounting frame 904 to move. The movement of the mounting frame 904 causes the elastic telescopic rod 905 to rise, which in turn causes the mounting plate 906 to rise. The rise of the mounting plate 906 then causes the contact roller 907 to rise, which in turn causes the numerical column 908 to rise. Simultaneously, the mounting frame 904 drives the laser displacement device 909 to rise. After rising a certain distance, the contact roller 907 is positioned at the welding joint. During the rotation of the pipeline, the contact roller 907 can fully contact the welded joint of the pipeline. If there are abnormal protrusions or depressions at the weld, the mounting plate 906 will move through the telescopic characteristics of the elastic telescopic rod 905, and drive the numerical column 908 to move. During the movement of the numerical column 908, the laser displacement device 909 can transmit the abnormal phenomenon to the external control terminal according to the movement distance signal of the numerical column 908. It can make preliminary observation and statistics on the welding quality, and directly improve the welding quality and effect of the device. A construction process for a welding device used for pipeline fabrication in high slope construction of water conservancy projects includes the following steps: Step 1: Before welding the high slope construction pipes, the operator can use an external transportation mechanism to place the two high slope construction pipes to be welded on the electric rollers 10 in sequence. The two electric rollers 10 can be moved by the CNC of the self-adjusting roller frame 4, and the distance between the two electric rollers 10 is controlled according to the size of the high slope construction pipes. Step 2: Ensure that the high slope construction pipeline is positioned on the two electric rollers 10. After the preparation work is completed, the cylinder 5 will start. The extension end of the cylinder 5 will drive the fixed plate 6 to rise. The movement of the fixed plate 6 will drive the positioning arc plate 7 to move. Step 3: The movement of the positioning arc plate 7 will drive the electric gripper 11 to rise synchronously. After the positioning arc plate 7 moves a certain distance, it will contact the high slope construction pipeline and provide support for it. After the high slope construction pipeline contacts the positioning arc plate 7, the electric gripper 11 will start. Step 4: The electric gripper 11 can clamp the pipeline for high slope construction, while the positioning arc plate 7 can align the pipeline workpiece. At this time, the multi-angle welding equipment can weld the two pipelines, which can directly improve the welding quality between the pipelines.

[0024] Overall working principle: During the movement of protrusion 808, protrusion 808 will drive the arc clamping plate 807 to move as well. During this movement, the arc clamping plate 807 will contact a portion of the pipe and clamp it securely, ensuring the stability of the pipe during welding and preventing vibration that could affect welding accuracy and quality. The arc collecting box 811 is positioned close to and directly below the welding area. During the welding process, weld slag and other debris generated by the multi-angle welding equipment will naturally fall into the arc collecting box 811, preventing them from contaminating other parts of the pipe. Debris scattered on the relevant equipment can affect welding operations. To prevent jamming during welding, the device's welding efficiency is improved. The rotation of the rotating column 901 drives the brush plate 903 to rotate. During rotation, the brush plate 903 can clean the debris and slag remaining at the weld seam between pipes, improving the quality and effect of pipe welding. As the numerical column 908 moves, the laser displacement device 909 can transmit abnormal phenomena to the external control terminal based on the movement distance signal of the numerical column 908. This allows for preliminary observation and statistical analysis of the welding quality, directly improving the welding quality and effect of the device.
