[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1 As shown;

[0025] A steel pipe welding spraying device comprises a mounting base 1.

[0026] In this embodiment, a steel pipe welding spray device is a specialized device specifically designed for welding and spraying steel pipes. It combines the two major processes of welding and spraying to achieve efficient and precise treatment of steel pipes. The welding portion is primarily responsible for connecting the various sections of the steel pipe, while the spraying portion is responsible for applying a coating to the steel pipe surface to achieve corrosion protection, rust prevention, and aesthetics. Conventional devices are relatively fixed in design and construction, making it difficult to easily adjust the position of the steel pipe. This means that during the welding process, if the angle or position of the steel pipe needs to be fine-tuned, additional tools or equipment may be required, or even the device may need to be disassembled and reinstalled, increasing operational complexity and time costs, and lacking sufficient adaptability. Furthermore, conventional devices are only suitable for steel pipes within a specific inner diameter range and cannot accommodate steel pipes of different inner diameters. This means that welding steel pipes of different inner diameters may require the replacement of different devices or complex adjustments, increasing operational costs and complexity. To address this technical problem, a welding spray assembly 2 is incorporated into this device.

[0027] More specifically:

[0028] like Figures 1 to 5 As shown:

[0029] In combination with the above content: the welding spray assembly 2 includes a mounting frame 21, a first motor 22 and a first pulley 23. The upper surface of the mounting base 1 is fixedly connected to the mounting frame 21, and the first motor 22 is installed on the outer side of one end of the mounting frame 21. The first pulley 23 is fixedly connected to the outer side of the main shaft of the first motor 22. The inner side of the end of the mounting frame 21 is fixedly connected to a connecting plate 24. The outer side of the end of the connecting plate 24 is rotatably connected to the second pulley 25. The first pulley 23 and the second pulley 25 are connected by a belt. The outer side of the end of the second pulley 25 is slidably connected to a placement plate 26. The upper surface of the placement plate 26 is fixedly connected to a fixing rod 27. The outer side of the end of the fixing rod 27 is rotatably connected to a plurality of connecting arms 28. The outer side of the end of the connecting arm 28 is rotatably connected to a support bar 29. The end of the mounting base 1 A welding and coating robot arm 210 is installed on the outside, and a second motor 211 is installed on the outside of the other end of the mounting frame 21. The outside of the end of the second motor 211 is fixedly connected to the first bevel gear 212, and the outside of the end of the mounting frame 21 is fixedly connected to the connecting barrel 216. The inside of the end of the mounting frame 21 is rotatably connected to the second bevel gear 213, and the screw rod 214 is fixedly connected to the end of the second bevel gear 213. The lower surface of the placement plate 26 is rotatably connected to the sleeve 215, and the sleeve 215 is threadedly connected to the screw rod 214. The first bevel gear 212 and the second bevel gear 213 are meshed and connected. A plurality of slides 217 are fixedly connected to the outer side of the end of the fixing rod 27 in a ring shape, and the lower surface of the support bar 29 is slidably connected to the inner side of the end of the slide 217. The outer side of the end of the support bar 29 is threadedly connected to a fixing nut 218.

[0030] In this embodiment: In this device, the upper surface of the mounting base 1 is fixedly connected with a mounting frame 21, and the mounting frame 21 is a U-shaped structure. A first motor 22 is installed on the outer side of the end of the mounting frame 21. When the user needs to use the device for welding and painting, the steel pipe can be sleeved on the outer side of the support bar 29, and a sliding barrel is provided on the outer side of the end of the fixing rod 27. The outer side of the end of the sliding barrel is rotatably connected to a plurality of connecting arms 28. At this time, the user can slide the support bar 29 on the inner side of the slide plate 217, and at the same time drive the sliding barrel on the outer side of the end of the connecting arm 28 to slide on the outer side of the end of the fixing rod 27 until each support bar 29 is against the inner wall of the steel pipe. After the position is suitable, the user can rotate the fixing nut 218 on the outer side of the end of the support bar 29. 8. The squeezing of the pairs of slides 217 can fix the positions of the multiple support bars 29. After the positions are fixed, the user can control the welding and coating robot arm 210 to weld and coat the steel pipe through the program. At this time, when the user needs to change the welding and coating position of the steel pipe, the user can start the first motor 22. The first motor 22 drives the first pulley 23 on the outside of its main shaft to rotate. The first pulley 23 can drive the second pulley 25 to rotate through the belt. The second pulley 25 then drives the placement plate 26 on the outside of its end to rotate, so that the steel pipe above the placement plate 26 can be rotated, which can change the welding and coating position of the steel pipe. When the user needs to change the welding and coating position of the steel pipe, the user can start the second motor 211. The second motor 2 11 drives the first bevel gear 212 on the outside of its main shaft to rotate, thereby driving the second bevel gear 213 meshing with the first bevel gear 212 to rotate. When the second bevel gear 213 rotates, it will simultaneously drive the sleeve 215 to move on the outside of the second bevel gear 213, and the sleeve 215 is rotationally connected to the lower surface of the placement plate 26. When the sleeve 215 moves upward, it will drive the placement plate 26 to move in the vertical direction, thereby changing the height of the steel pipe on the upper surface of the placement plate 26. The rotation and lifting of the steel pipe on the upper surface of the placement plate 26 can be achieved through the second pulley 25 and the screw rod 214. The lifting and rotating design makes it easy to adjust the steel pipe between different heights and angles, greatly improving the flexibility of operation without manual moving or adjustment. The position of the steel pipe is adjusted, which reduces the labor intensity of the operator and improves the safety of operation. By adjusting the height and angle of the steel pipe, it can ensure that the welding and painting robot arm 210 maintains the best distance and angle with the surface of the steel pipe, thereby improving the welding and painting effects. Especially when processing complex welds or specific painting effects, the lifting and rotating devices can provide more precise position adjustment to ensure the quality of welding and painting. At the same time, the inner diameter of the steel pipe can be adaptively adjusted through the connecting arm 28 and the support bar 29. The fixing device that adapts to the inner diameter of the steel pipe can quickly and accurately adapt to steel pipes of different sizes without the need for frequent replacement of fixtures or manual adjustment, thereby significantly improving the efficiency and flexibility of operation and expanding the scope of use and versatility of the equipment.

[0031] Going further:

[0032] In an optional embodiment, the support strip 29 is made of rubber.

[0033] In this embodiment: the support strip 29 is made of rubber. The high elasticity of rubber can effectively buffer the impact and vibration caused by vibration or thermal stress during the welding process, thereby protecting the steel pipe from excessive stress or damage. At the same time, the rubber material of the support strip 29 can reduce the vibration and noise generated during the welding process, providing a quieter and more comfortable working environment, which is beneficial to the maintenance of operators and equipment. The rubber support strip 29 usually has good insulation properties, which helps to reduce the potential harm of electric sparks that may be generated during welding to the surrounding environment, especially in flammable and explosive environments.

[0034] Going further:

[0035] In an optional embodiment, a plurality of universal wheels 219 are installed on the lower surface of the mounting base 1 .

[0036] In this embodiment, a plurality of universal wheels 219 are mounted on the lower surface of the mounting base 1. By installing the universal wheels 219, operators can easily move and position the steel pipe welding device, enabling quick and convenient transfers, whether at a work site or in a warehouse. This not only improves work efficiency and reduces the labor intensity of manual handling, but also enables the device to adapt to more complex and changing work environments. Furthermore, the design of the universal wheels 219 makes the device more stable during movement, reducing equipment damage and safety incidents caused by accidental collisions or operational errors. The installation of the universal wheels 219 brings great convenience and safety to the steel pipe welding device.

[0037] Going further:

[0038] In an optional embodiment, a retaining ring 220 is fixedly connected to the outer side of the end of the support bar 29 .

[0039] In this embodiment, the placement plate 26 is a plate-shaped structure, and the retaining ring 220 and placement plate 26 form a circular container. During welding, welding spatter, smoke, and other harmful substances may be generated. The placement plate 26 and retaining ring 220 effectively collect these waste materials, preventing them from being released into the environment, thereby protecting the work environment and worker health. If welding waste is not promptly removed, it may accumulate in the work area, affecting the normal progress of welding. The placement plate 26 and retaining ring 220 can quickly collect waste, reducing cleaning time and workload, and improving the overall efficiency of welding.

[0040] Working principle: In this device, the upper surface of the mounting base 1 is fixedly connected with a mounting frame 21, and the mounting frame 21 is a U-shaped structure. A first motor 22 is installed on the outer side of the end of the mounting frame 21. When the user needs to use the device for welding and painting, the steel pipe can be sleeved on the outer side of the support bar 29. A sliding barrel is provided on the outer side of the end of the fixed rod 27. The outer side of the end of the sliding barrel is rotatably connected to multiple connecting arms 28. At this time, the user can slide the support bar 29 on the inner side of the slide plate 217, and at the same time drive the sliding barrel on the outer side of the end of the connecting arm 28 to slide on the outer side of the end of the fixed rod 27 until each support bar 29 is against the inner wall of the steel pipe. After the position is suitable, the user can rotate the fixing nut 218 on the outer side of the end of the support bar 29 to fix the slide plate through the fixing nut 218 The extrusion of 217 can fix the positions of multiple support bars 29. After the positions are fixed, the user can control the welding and painting robot arm 210 through the program to weld and paint the steel pipe. At this time, when the user needs to change the welding and painting position of the steel pipe, the user can start the first motor 22, and the first motor 22 drives the first pulley 23 on the outside of its main shaft to rotate. The first pulley 23 can drive the second pulley 25 to rotate through the belt, and the second pulley 25 then drives the placement plate 26 on the outside of its end to rotate, so as to rotate the steel pipe above the placement plate 26, which can change the welding and painting position of the steel pipe. When the user needs to change the welding and painting position of the steel pipe, the user can start the second motor 211, and the second motor 211 drives its main shaft The first bevel gear 212 on the outside rotates, thereby driving the second bevel gear 213 meshed with the first bevel gear 212 to rotate. When the second bevel gear 213 rotates, it will simultaneously drive the sleeve 215 to move outside the second bevel gear 213, and the sleeve 215 is rotationally connected to the lower surface of the placement plate 26. When the sleeve 215 moves upward, it will drive the placement plate 26 to move in the vertical direction, thereby changing the height of the steel pipe on the upper surface of the placement plate 26. The rotation and lifting of the steel pipe on the upper surface of the placement plate 26 can be achieved through the second pulley 25 and the screw rod 214. The lifting and rotating design makes it easy to adjust the steel pipe between different heights and angles, greatly improving the flexibility of operation, eliminating the need for manual movement or adjustment of the steel pipe position, and reducing The labor intensity of the operator is reduced, and the safety of the operation is also improved. By adjusting the height and angle of the steel pipe, the welding and coating robot arm 210 can be ensured to maintain the best distance and angle with the surface of the steel pipe, thereby improving the welding and coating effects. Especially when processing complex welds or specific coating effects, the lifting and rotating device can provide more precise position adjustment to ensure the quality of welding and coating. At the same time, the inner diameter of the steel pipe can be adapted to the inner diameter of the steel pipe through the connecting arm 28 and the support bar 29. The fixture device that adapts to the inner diameter of the steel pipe can quickly and accurately adapt to steel pipes of different sizes without the need for frequent replacement of fixtures or manual adjustment, thereby significantly improving the efficiency and flexibility of the operation and expanding the scope of use and versatility of the equipment. The material of the support bar 29 is rubber.The high elasticity of rubber can effectively buffer the impact and vibration caused by vibration or thermal stress during the welding process, thereby protecting the steel pipe from excessive stress or damage. At the same time, the rubber material of the support bar 29 can reduce the vibration and noise generated during the welding process, providing a quieter and more comfortable working environment, which is beneficial to both operators and equipment maintenance. The rubber support bar 29 usually has good insulation properties, which helps to reduce the potential harm of electric sparks that may be generated during welding to the surrounding environment, especially in flammable and explosive environments. A plurality of universal wheels 219 are installed on the lower surface of the mounting base 1. By installing the universal wheels 219, the operator can easily move and position the steel pipe welding device, whether at the work site or in the warehouse, and can achieve fast and convenient transfer.

The placement plate 26 is a plate-shaped structure, and the retaining ring 220 is combined with the placement plate 26 to form a circular container. Welding spatter, smoke and other harmful substances may be generated during the welding process. The placement plate 26 and the retaining ring 220 can effectively collect these waste materials and prevent them from being scattered into the environment, thereby protecting the working environment and the health of workers.
