Description

Technical Field

[0001] The present invention relates to the technical field of welding, and particularly to a welding device and method for high-altitude pipelines. Background Art

[0002] In thermal power plants, high-altitude pipelines are mainly used to transport media such as high-temperature and high-pressure steam, fuels (such as pulverized coal, gas), and cooling water. The pipelines are mostly distributed in the high-altitude areas of boiler steel structures and steam turbine workshops, arranged in a three-dimensional intersection. The main steam pipelines are often located dozens of meters above the ground (such as the top of the boiler, near the chimney), and high-altitude operations are required.

[0003] For large-thick-wall pipelines, continuous welding is required for dozens of hours. It is easy for welders to get fatigued during high-altitude operations, and the operations at overhead welding and vertical welding positions are extremely difficult. Relying on welders for high-altitude operations has a high labor intensity, low efficiency, and there are potential hazards such as falling and welding spark splashing. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A welding device for high-altitude pipelines, comprising: A welding component, which is used for welding high-altitude pipelines. A collection component is fixedly connected to the inner side of the welding component. Connecting shafts are fixedly connected to both sides of the welding component, and a support component is fixedly connected to the other end of the connecting shaft; The welding component includes two welding frames. Brackets are fixedly connected to both sides of the welding frame. The middle parts of the two brackets are fixedly connected by a fixing pin. A motor is fixedly connected to one side of the bracket. A driving gear is rotatably connected to the inner side of the two brackets. A motor is fixedly connected to the side of the bracket, and the output end of the motor is fixedly connected to the middle part of the driving gear. A driven gear is rotatably connected to the middle part of the side of the two welding frames. The side of the driven gear is meshed and connected to the side of the driving gear. A welding head is fixedly connected to the inner side of the driving gear. An installation groove is formed on the side of the welding frame, and the side of the welding frame is fixedly connected to one end of the connecting shaft; After starting the motor, the output end of the motor drives the driving gear to rotate in the middle of the two brackets. The driving gear is meshed and connected to the driven gear. Utilizing the stable meshing relationship between the gears, the power of the motor is accurately transmitted to the driven gear; Driven by the driving gear, the driven gear makes a circular motion within the welding frame. Compared with manual welding, the welding efficiency and precision can be greatly improved, the labor intensity and error rate of manual operation can be reduced. At the same time, the driven gear drives the welding head to perform welding operations along the circumference of the pipeline. The welding head can automatically adjust the angle and position according to the preset trajectory or real-time monitoring data to ensure that the welding torch and the pipeline groove always maintain the best welding posture.

[0005] Preferably, the collecting component includes a collecting box, the side of the collecting box is fixedly connected to the inner side of the installation groove, a net plate is fixedly connected to one side of the collecting box close to the installation groove, a connecting box is fixedly connected to the bottom of the inner cavity of the collecting box, a baffle is fixedly connected to the top of the connecting box, a filter screen is fixedly connected to the middle of the inner cavity of the connecting box, a rotating mechanism is evenly arranged on the filter screen, the top of the rotating mechanism is rotatably connected to the bottom of the filter screen, a filtering box is fixedly connected to the bottom of the inner cavity of the connecting box, and a filtering mechanism is fixedly connected to the middle of the bottom of the connecting box.

[0006] Preferably, when the pipeline welding operation is started, the filtering mechanism is turned on to generate suction, forming an air flow field at the entrance of the collecting box, adsorbing the welding slag and harmful waste gas generated during the welding process, preventing pollutants from spreading to the working environment, ensuring the health of welders and the safety of high-altitude operations. After the welding slag and waste gas are initially intercepted by large particles by the net plate, they enter the collecting box for classification treatment.

[0007] Preferably, a baffle is arranged inside the collecting box to form a tortuous air flow channel, which can realize the classified collection of welding slag. Larger-sized welding slag particles directly fall to the bottom of the collecting box and remain after colliding with the baffle due to inertia, while smaller particles continue to move downward with the air flow. This classification mechanism effectively reduces the risk of filter screen blockage, extends the equipment maintenance cycle, and reduces the difficulty of high-altitude cleaning.

[0008] The fine welding slag and waste gas passing through the baffle enter the connecting box through the filter screen and fall to the top of the filtering box. At this time, the rotating mechanism evenly scatters the welding slag passing through the filter screen, avoiding the decrease in filtration efficiency caused by local accumulation, and ensuring that the welding slag gradually falls through the pores of the filtering box after being dispersed, realizing more thorough solid-gas separation.

[0009] The waste gas then penetrates the filtering box and enters the purification module inside the filtering mechanism, efficiently removing the harmful components in the waste gas, realizing the environmental protection and harmless treatment of welding waste.

[0010] Preferably, the rotating mechanism includes a rotating shaft, the top of the rotating shaft is rotatably connected to the bottom of the filter screen, rotating rods are fixedly connected to both the upper and lower sides of the rotating shaft, the number of the rotating rods is four, the four rotating rods are evenly arranged around the rotating shaft, and an impact block is fixedly connected to the end of the rotating rod away from the rotating shaft.

[0011] Preferably, after the filtering mechanism is started, the suction generated by it is not only used to adsorb welding waste gas and slag, but also drives the rotating shaft to rotate through the evenly distributed rotating rods. The impact blocks connected to the ends of the rotating rods collide dynamically with the welding slag continuously passing through the filter screen under the drive of the air flow, and the welding slag is dispersed by using the impact force. Compared with the traditional static filtering method, it can actively intervene in the falling path of the welding slag and prevent it from gathering in large quantities in the central area at the top of the filtering box.

[0012] Preferably, the filtering mechanism includes a filtering cylinder, the side surface of the filtering cylinder is fixedly connected to the middle of the inner cavity bottom of the connection box, a filtering plate is fixedly connected to the top of the filtering cylinder, a support plate is fixedly connected to the middle of the inner cavity of the filtering cylinder, a rotating assembly is rotatably connected to the inner side of the support plate, a bottom plate is fixedly connected to the inner side of the filtering cylinder, a driving member is fixedly connected to the bottom of the bottom plate, and the output end of the driving member is fixedly connected to the bottom of the rotating assembly.

[0013] Preferably, when the welding operation starts, the driving member is started, and its output end drives the rotating assembly to rotate on the bottom plate. An appropriate amount of activated carbon particles are filled between the support plate and the filtering plate. When the waste gas containing pollutants enters the filtering cylinder, the activated carbon particles utilize their rich pore structure and strong adsorption capacity to effectively adsorb the harmful components in the waste gas.

[0014] Preferably, the rotating assembly includes a rotating shaft, the side surface of the rotating shaft is rotatably connected to the inner side of the support plate, the top of the rotating shaft is rotatably connected to the bottom of the filtering plate, a fan blade is fixedly connected to the bottom of the rotating shaft, the side of the fan blade away from the rotating shaft is fixedly connected to the output end of the driving member, rotating plates are fixedly connected to both the upper and lower sides of the rotating shaft, a round rod is fixedly connected to the side surface of the rotating plate, and a rotating frame is fixedly connected to the side of the rotating plate away from the rotating shaft.

[0015] Preferably, after the driving member is started, its output end drives the fan blade to rotate at a high speed. The rotation of the fan blade generates a strong suction force, sucking the waste gas and welding slag generated during the welding process into the connection housing. This active negative pressure collection method can capture the pollutants suspended in the air more efficiently compared to passive adsorption, avoid the splashing and diffusion of welding slag and the escape of harmful gases, effectively improve the high-altitude operation environment, and reduce the risk of welders inhaling harmful substances.

[0016] Preferably, the support component includes two support housings, the side surfaces of the support housings are fixedly connected to one end of the connection shaft away from the welding frame, fasteners are threadedly connected to the inner sides of the two support housings, rollers are rotatably connected to the middle of the side surfaces of the support housings, sliding rods are slidably connected to both sides of the inner walls of the support housings, clamping plates are fixedly connected to the other ends of the sliding rods, rollers are rotatably connected to both sides of the clamping plates, a first spring is sleeved on the sliding rods, one end of the first spring is fixedly connected to the clamping plate, and the other end of the first spring is fixedly connected to the inner side of the support housing.

[0017] Preferably, when the angle or position of the support shell needs to be adjusted, the support shell is directly rotated. Since rollers and wheels are rotatably arranged on the inner side of the support shell, the rollers convert the sliding friction between the clamping plate and the pipe into rolling friction, which greatly reduces the resistance and enables the operator to more easily and accurately adjust the relative angle between the support shell and the pipe; the rollers assist the support shell to move along the axial direction of the pipe, thereby realizing rapid positioning of the welding position, avoiding the adjustment difficulties caused by traditional rigid clamping, improving the efficiency of high-altitude operations, and reducing manpower consumption.

[0018] A method for welding a high altitude pipeline comprises the following steps: S1: The electric hanging basket is firmly installed on the bearing structure above the pipeline, with high protection railings set up around it, anti-slip steel plates laid on the bottom to enhance stability, and anti-fall nets hung on the outside to form a three-dimensional protection system to ensure the safety of operators; S2: Use steel pipes to build double-row scaffolding, and lay scaffolding boards on the operating floor as a working platform. At the same time, install a stable ladder to facilitate people to go up and down, and set up a diagonal bracing structure to enhance the overall rigidity of the scaffolding to ensure that it meets the load-bearing and safety requirements of high-altitude operations; S3: Install the support components symmetrically on both sides of the pipe weld, and move the support components to adjust them to the appropriate position along the circumference of the pipe so that the welding components can be accurately abutted against the part to be welded. Then, use the threaded connector to fasten the two support components, and fix the welding device firmly on the pipe surface by mechanical locking, providing a stable foundation for automatic welding. S4: Start the welding parts, and the equipment automatically welds along the circumference of the pipeline. During the welding process, the welding gun accurately controls the angle and swing amplitude to ensure full fusion with both sides of the groove. At the same time, the system monitors the molten pool temperature in real time, automatically adjusts the welding current parameters, dynamically controls the molten pool state, and ensures the quality of weld formation and welding strength; S5: When the welding operation starts, turn on the supporting collection components to collect the welding slag, metal spatter and harmful waste gas generated during the welding process through a combination of negative pressure adsorption and physical interception, so as to avoid the spread of pollutants, reduce the difficulty of high-altitude cleaning and ensure the safety of the working environment.

[0019] The present invention provides a welding device and method for high-altitude pipelines, which have the following beneficial effects: 1. The high-altitude pipeline welding device and method are provided with welding components. The driven gear is driven by the driving gear to perform circular motion in the welding frame. Compared with manual hand-held welding, the welding efficiency and accuracy can be greatly improved, and the labor intensity and error rate of manual operation can be reduced. At the same time, the driven gear drives the welding head to perform welding operations along the circumference of the pipeline. The welding head can automatically adjust the angle and position according to the preset trajectory or real-time monitoring data to ensure that the welding gun and the pipeline groove always maintain the best welding posture.

[0020] 2. The welding device and method for the high-altitude pipeline are provided with a collection component. When the pipeline welding operation is started, the filtering mechanism is activated to generate suction, forming an air flow field at the entrance of the collection box to adsorb the welding slag and harmful waste gas generated during the welding process, preventing pollutants from spreading to the working environment and ensuring the health of welders and the safety of high-altitude operations. After the welding slag and waste gas are initially intercepted by large particles through the mesh plate, they enter the collection box for classification treatment.

[0021] 3. The welding device and method for the high-altitude pipeline are provided with a rotating mechanism. When the welding slag falls through the filter screen, the impact blocks impact it at high frequencies and from multiple angles, dispersing the welding slag to the surrounding areas at the top of the filter box, improving the uniformity of the welding slag distribution, preventing potential blockage caused by local accumulation, keeping the ventilation channel continuously unobstructed, and avoiding the attenuation of suction caused by the accumulation of welding slag through the dispersion of welding slag, ensuring the continuous and efficient collection of waste gas and welding slag.

[0022] 4. The welding device and method for the high-altitude pipeline are provided with a rotating assembly. While the fan blades are rotating, through the linkage design of the rotating shaft and the rotating plate, the power is synchronously transmitted to the rotating frame. As the rotating frame drives the continuous rotation of the round rod, it fully stirs the activated carbon particles placed between the support plate and the filter plate, increasing the contact area and contact time between the activated carbon and the waste gas, breaking the adsorption blind spots existing in traditional static filtration. With its rich pore structure, the activated carbon can more thoroughly adsorb impurities such as metal dust and nitrogen oxides in the waste gas, improving the waste gas purification efficiency.

[0023] 5. The welding device and method for the high-altitude pipeline are provided with a support component. When it is necessary to adjust the angle or position of the support housing, directly rotate the support housing. Since the roller and the roller wheel are rotatably arranged inside the support housing, the roller converts the sliding friction between the clamping plate and the pipeline into rolling friction, greatly reducing the resistance, enabling the operator to more easily and accurately adjust the relative angle between the support housing and the pipeline; the roller wheel then assists the support housing to move axially along the pipeline, realizing the rapid positioning of the welding position, avoiding the adjustment difficulties caused by traditional rigid clamping, improving the high-altitude operation efficiency, and reducing manpower consumption.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a welding device for high-altitude pipelines, including: The welding component 1 is used for welding high-altitude pipelines. The collection component 4 is fixedly connected to the inner side of the welding component 1. Connecting shafts 2 are fixedly connected to both sides of the welding component 1, and the other ends of the connecting shafts 2 are fixedly connected to the support component 3.

[0028] Please refer to Figures 1 - 4, the welding component 1 includes two welding frames 11. Both sides of the welding frame 11 are fixedly connected with brackets 12. The middle parts of the two brackets 12 are fixedly connected by a fixing pin. One side of the bracket 12 is fixedly connected with a motor 13. The inner sides of the two brackets 12 are rotatably connected with a driving gear 14. The side of the bracket 12 is fixedly connected with a motor 13. The output end of the motor 13 is fixedly connected with the middle part of the driving gear 14. The middle parts of the sides of the two welding frames 11 are rotatably connected with a driven gear 15. The side of the driven gear 15 is meshed and connected with the side of the driving gear 14. The inner side of the driving gear 14 is fixedly connected with a welding head 16. An installation groove 17 is formed on the side of the welding frame 11. The side of the welding frame 11 is fixedly connected with one end of a connecting shaft 2.

[0029] After starting the motor 13, the output end of the motor 13 drives the driving gear 14 to rotate in the middle parts of the two brackets 12. The driving gear 14 is meshed and connected with the driven gear 15. By using the stable meshing relationship between the gears, the power of the motor 13 is accurately transmitted to the driven gear 15.

[0030] Driven by the driving gear 14, the driven gear 15 makes a circular motion inside the welding frame 11. Compared with manual welding, it can greatly improve the welding efficiency and accuracy, reduce the labor intensity and error rate of manual operation. At the same time, the driven gear 15 drives the welding head 16 to perform welding operations along the circumference of the pipeline. The welding head 16 can automatically adjust the angle and position according to the preset trajectory or real-time monitoring data to ensure that the welding torch and the pipeline groove always maintain the best welding posture.

[0031] Please refer to Figures 1 - 5 , the present invention provides a technical solution: The collection component 4 includes a collection box 41. The side of the collection box 41 is fixedly connected with the inner side of the installation groove 17. One side of the collection box 41 close to the installation groove 17 is fixedly connected with a mesh plate 42. The bottom of the inner cavity of the collection box 41 is fixedly connected with a connection box 43. The top of the connection box 43 is fixedly connected with a baffle 44. The middle part of the inner cavity of the connection box 43 is fixedly connected with a filter screen 45. A rotating mechanism 47 is evenly arranged on the filter screen 45. The top of the rotating mechanism 47 is rotatably connected with the bottom of the filter screen 45. The bottom of the inner cavity of the connection box 43 is fixedly connected with a filter box 46. The middle part of the bottom of the connection box 43 is fixedly connected with a filtering mechanism 48.

[0032] When the pipeline welding operation is started, the filtering mechanism 48 is turned on to generate suction, forming an air flow field at the entrance of the collection box 41 to adsorb the welding slag and harmful waste gas generated during the welding process, avoiding the diffusion of pollutants to the working environment and ensuring the health of welders and the safety of high-altitude operations. After the welding slag and waste gas are initially intercepted by large particles by the mesh plate 42, they enter the collection box 41 for grading treatment.

[0033] Inside the collection box 41, a baffle 44 is provided to form a tortuous air flow channel, enabling the hierarchical collection of welding slag. After larger-sized welding slag particles collide with the baffle 44 due to inertia, they directly fall to the bottom of the collection box 41 for retention, while smaller particles continue to descend with the air flow. This grading mechanism effectively reduces the risk of clogging of the filter screen 45, extends the equipment maintenance cycle, and reduces the difficulty of high-altitude cleaning.

[0034] The fine welding slag and waste gas passing through the baffle 44 enter the connection box 43 through the filter screen 45 and fall onto the top of the filter box 46. At this time, the rotating mechanism 47 evenly scatters the welding slag passing through the filter screen 45 to avoid a decrease in filtration efficiency caused by local accumulation, ensuring that the welding slag gradually falls through the pores of the filter box 46 after being dispersed, achieving more thorough solid-gas separation.

[0035] The waste gas then penetrates the filter box 46 and enters the purification module inside the filtration mechanism 48, effectively removing harmful components in the waste gas and realizing the environmental protection and harmlessness of welding waste treatment.

[0036] Please refer to Figures 1 - 6 , the rotating mechanism 47 includes a rotating shaft 471. The top of the rotating shaft 471 is rotatably connected to the bottom of the filter screen 45. Rotating rods 472 are fixedly connected to both the upper and lower sides of the rotating shaft 471. The number of rotating rods 472 is four, and the four rotating rods 472 are evenly arranged around the rotating shaft 471. An impact block 473 is fixedly connected to the end of the rotating rod 472 away from the rotating shaft 471.

[0037] After the filtration mechanism 48 is started, the suction force it generates is not only used to adsorb welding waste gas and welding slag, but also drives the rotation of the rotating shaft 471 through the evenly distributed rotating rods 472. The impact block 473 connected to the end of the rotating rod 472 dynamically impacts the welding slag continuously passing through the filter screen 45 under the drive of the air flow. By using the impact force, the welding slag is dispersed. Compared with the traditional static filtration method, it can actively intervene in the falling path of the welding slag and prevent it from accumulating in large quantities in the central area of the top of the filter box 46.

[0038] When the welding slag falls through the filter screen 45, the impact block 473 impacts at high frequency and from multiple angles, dispersing the welding slag to the periphery of the top of the filter box 46, improving the uniformity of the welding slag distribution, preventing the formation of blockage hazards due to local accumulation, keeping the ventilation channel continuously unobstructed, and avoiding the attenuation of the suction force caused by the accumulation of welding slag, ensuring the continuous and efficient collection of waste gas and welding slag.

[0039] The dynamic impact of the impact block 473 can also timely shake off the welding slag attached to the surface of the filter screen 45, prevent it from clogging the pores of the filter screen 45, extend the service life of the filter screen 45, reduce the frequent maintenance operations due to the clogging of the filter screen 45 during high-altitude operations, and thus improve the safety and working efficiency of the entire welding operation.

[0040] Please refer to Figures 1 - 7, the filtering mechanism 48 includes a filtering cylinder 481. The side of the filtering cylinder 481 is fixedly connected to the middle of the bottom inside the connection box 43. The top of the filtering cylinder 481 is fixedly connected to a filtering plate 482. The middle of the inner cavity of the filtering cylinder 481 is fixedly connected to a support plate 483. The inner side of the support plate 483 is rotatably connected to a rotating assembly 486. The inner side of the filtering cylinder 481 is fixedly connected to a bottom plate 484. The bottom of the bottom plate 484 is fixedly connected to a driving member 485. The output end of the driving member 485 is fixedly connected to the bottom of the rotating assembly 486.

[0041] When the welding operation starts, the driving member 485 is started. Its output end drives the rotating assembly 486 to rotate on the bottom plate 484. An appropriate amount of activated carbon particles is filled between the support plate 483 and the filtering plate 482. When the waste gas containing pollutants enters the filtering cylinder 481, the activated carbon particles utilize their rich pore structure and strong adsorption capacity to effectively adsorb the harmful components in the waste gas.

[0042] At the same time, during the continuous air intake process of the rotating assembly 486, the activated carbon particles between the support plate 483 and the filtering plate 482 are stirred, enabling them to come into full contact with the waste gas, ensuring that the pollutants in the waste gas are more thoroughly adsorbed and filtered, and improving the purification effect.

[0043] The clean waste gas that has been fully filtered by the activated carbon particles is discharged to the outside through the bottom plate 484, reducing the pollution to the atmospheric environment.

[0044] Please refer to Figures 1 - 8 , the rotating assembly 486 includes a rotating shaft 4861. The side of the rotating shaft 4861 is rotatably connected to the inner side of the support plate 483. The top of the rotating shaft 4861 is rotatably connected to the bottom of the filtering plate 482. The bottom of the rotating shaft 4861 is fixedly connected to a fan blade 4865. The side of the fan blade 4865 away from the rotating shaft 4861 is fixedly connected to the output end of the driving member 485. Both the upper and lower sides of the rotating shaft 4861 are fixedly connected to rotating plates 4862. The side of the rotating plate 4862 is fixedly connected to a round rod 4863. The side of the rotating plate 4862 away from the rotating shaft 4861 is fixedly connected to a rotating frame 4864.

[0045] When the driving member 485 is started, its output end drives the fan blade 4865 to rotate at a high speed. The rotation of the fan blade 4865 generates a strong suction force, sucking the waste gas and welding slag generated during the welding process into the connection housing. This active negative pressure collection method can capture the pollutants suspended in the air more efficiently compared to passive adsorption, avoiding the splashing and diffusion of welding slag and the escape of harmful gases, effectively improving the high-altitude operation environment, and reducing the risk of welders inhaling harmful substances.

[0046] While the fan blade 4865 is rotating, through the linkage design of the rotating shaft 4861 and the rotating plate 4862, the power is synchronously transmitted to the rotating frame 4864. As the rotating frame 4864 drives the continuous rotation of the round rod 4863, it fully agitates the activated carbon particles placed between the support plate 483 and the filter plate 482, enhancing the contact area and contact time between the activated carbon and the waste gas, breaking the adsorption blind spots existing in traditional static filtration. With its rich pore structure, the activated carbon can more thoroughly adsorb impurities such as metal dust and nitrogen oxides in the waste gas, improving the waste gas purification efficiency.

[0047] The continuous agitation can also effectively prevent the activated carbon particles from caking due to long-term use, extend the service life of the activated carbon, reduce the maintenance frequency of high-altitude equipment, lower the operation risks and costs brought by replacing the filter material, and achieve the high efficiency of welding waste treatment.

[0048] Please refer to Figures 1 - 9 , the present invention provides a technical solution: The support member 3 includes two support shells 31. The side of the support shell 31 is fixedly connected to one end of the connecting shaft 2 away from the welding frame 11. A fastener 32 is threadedly connected to the inner side of the two support shells 31. A roller 33 is rotatably connected to the middle of the side of the support shell 31. Both sides of the inner wall of the support shell 31 are slidably connected with a sliding rod 34. The other end of the sliding rod 34 is fixedly connected with a clamping plate 35. Both sides of the clamping plate 35 are rotatably connected with a roller 36. A first spring 37 is sleeved on the sliding rod 34. One end of the first spring 37 is fixedly connected with the clamping plate 35, and the other end of the first spring 37 is fixedly connected with the inner side of the support shell 31.

[0049] The support shell 31 is hoisted and sleeved outside the pipeline. By rotating the fasteners 32 in the middle of the two support shells 31, it is preliminarily limited, quickly positioning the support shell 31 to ensure that the device is coaxial with the pipeline, providing a basic guarantee for the subsequent welding accuracy. At the same time, the clamping plate 35 drives the roller 36 to contact and abut against the side of the pipeline, forming an initial support structure.

[0050] When it is necessary to adjust the angle or position of the support shell 31, directly rotate the support shell 31. Since the roller 36 is rotatably arranged inside the support shell 31 and the roller 33, the roller 36 converts the sliding friction between the clamping plate 35 and the pipeline into rolling friction, greatly reducing the resistance, enabling the operator to more easily and accurately adjust the relative angle between the support shell 31 and the pipeline; the roller 33 assists the support shell 31 to move axially along the pipeline, realizing the rapid positioning of the welding position, avoiding the adjustment difficulties caused by traditional rigid clamping, improving the high-altitude operation efficiency, and reducing the manpower consumption.

[0051] After determining the position of the support housing 31, continuously tighten the fasteners 32 on both sides of its middle. As the fasteners 32 are tightened, the support housing 31 fits tightly against the side of the pipeline and is fixed. At the same time, under the action of the extrusion force, the clamping plate 35 moves towards the inside of the support housing 31 through the slide rod 34 and compresses the first spring 37, finally driving the roller 36 to abut against the inside of the support housing 31. This elastic clamping design can not only ensure the stable connection between the support housing 31 and the pipeline, but also prevent excessive extrusion from damaging the surface of the pipeline.

After the fixation is completed, the pipeline can be welded through the welding component 1.

[0052] Please refer to Figure 10 , the present invention provides a technical solution: a welding method for high-altitude pipelines, including the following steps: S1: Stably install the electric hanging basket on the bearing structure above the pipeline, set height protection fences around, lay anti-slip steel plates at the bottom to enhance stability, and hang anti-fall nets on the outside to form a three-dimensional protection system to ensure the safety of the operators; S2: Build a double-row scaffolding with steel pipes, fully lay scaffolding boards on the operating layer as the working platform, install a stable ladder for personnel to go up and down at the same time, and set a diagonal bracing structure to enhance the overall rigidity of the scaffolding to ensure meeting the load-bearing and safety requirements for high-altitude operations; S3: Symmetrically install the support components 3 on both sides of the pipeline weld. By moving the support components 3, adjust them along the circumferential direction of the pipeline to a suitable position, so that the welding component 1 accurately abuts against the part to be welded. Subsequently, use threaded connectors to fasten the two support components 3, and firmly fix the welding device on the surface of the pipeline through mechanical locking to provide a stable foundation for automatic welding; S4: Start the welding component 1, and the equipment automatically welds along the circumference of the pipeline. During the welding process, the welding torch accurately controls the angle and swing amplitude to ensure full fusion with both sides of the groove. At the same time, the system real-time monitors the temperature of the molten pool, and dynamically controls the state of the molten pool by automatically adjusting the welding current parameters to ensure the forming quality and welding strength of the weld; S5: While starting the welding operation, turn on the supporting collection component 4, and synchronously collect the welding slag, metal spatter and harmful waste gas generated during the welding process through a combination of negative pressure adsorption and physical interception, avoiding the diffusion of pollutants, reducing the difficulty of high-altitude cleaning, and ensuring the safety of the working environment.
