[0030] Straight seam welding on the outside of a steel pipe refers to a method of welding the steel plate or strip into a pipe shape and then welding the pipe in a straight line on the outside of the pipe during the manufacturing process of the steel pipe. However, when using semi-automatic submerged arc welding, it is difficult to recycle the flux, resulting in a low flux recovery rate, causing waste of materials, and is not conducive to environmental protection and controlling production costs.

[0031] In order to solve the technical problem, the utility model provides a steel pipe outer straight seam welding platform.

[0032] See also Figures 1 to 3 In one embodiment of the utility model, the steel pipe outer straight seam welding platform includes a bracket 100, a welding mechanism 200 and a flux recovery mechanism 300. The bracket 100 has an installation platform 110, and an operation space 120 for accommodating the steel pipe is formed below the installation platform 110; the welding mechanism 200 is slidably installed on the installation platform 110 along the vertical direction; the welding mechanism 200 has a welding output end, which is arranged in the operation space 120 and is used for welding the outer straight seam of the steel pipe; the flux recovery mechanism 300 is spaced apart from the welding mechanism 200, and the flux recovery mechanism 300 is slidably installed on the installation platform 110 along the vertical direction; the flux recovery mechanism 300 has a flux recovery end, and the position of the flux recovery end corresponding to the welding output end is arranged in the operation space 120.

[0033] It should be understood that since the welding mechanism 200 and the flux recovery mechanism 300 are both slidably installed on the installation platform 110 in the vertical direction, when welding the outer straight seam of the steel pipe, the welding end of the welding mechanism 200 and the flux recovery end of the flux recovery mechanism 300 can be raised and lowered in the operating space 120 to adapt to steel pipes of different sizes and adapt to the height changes of the welding position, thereby increasing the flexibility of operation and being able to more accurately control the welding process, helping to ensure the uniformity and continuity of the weld, thereby improving the strength and durability of the entire welding structure. The use of the welding mechanism 200 and the flux recovery mechanism 300 also reduces the direct contact between operators and the high-temperature welding area, thereby enhancing the safety of the workplace.

[0034] The flux recovery mechanism 300 not only helps to reduce material waste in the production process, but also reduces the impact on the environment. By recycling and reusing the flux, the demand for new flux can be significantly reduced, reducing production costs.

[0035] In addition, through mechanized and semi-automated welding and flux recovery processes, production speed can be accelerated and labor intensity can be reduced. The increased degree of automation makes continuous production possible, greatly improving the overall efficiency of the production line.

[0036] In the technical solution provided by the utility model, through the welding mechanism 200 and the flux recovery mechanism 300 which are slidably installed on the installation platform 110 along the vertical direction, when welding the outer straight seam of the steel pipe, the welding end of the welding mechanism 200 and the flux recovery end of the flux recovery mechanism 300 can be raised and lowered in the operating space 120 to adapt to steel pipes of different sizes and adapt to the height changes of the welding position, thereby increasing the flexibility of operation and being able to more accurately control the welding process, helping to ensure the uniformity and continuity of the weld, thereby improving the strength and durability of the entire welding structure. The flux recovery mechanism 300 recycles unused flux, which not only helps to reduce material waste in the production process, but also reduces the impact on the environment and reduces production costs.

[0037] For details, please continue to see Figure 1 In an embodiment of the utility model, the welding mechanism 200 includes a first guide member 210, a first driving member, a first mounting assembly 220 and a welding gun 230. The first guide member 210 is mounted on the mounting platform 110. The welding gun 230 is vertically slidably mounted on the first guide member 210 through the first mounting assembly 220. The first driving member is mounted on the first guide member 210. The first driving member is connected to the first mounting assembly 220 and is used to drive the first mounting assembly 220 to drive the welding gun 230 to rise and fall in the operating space 120. The welding gun 230 is formed with a welding output end.

[0038] It should be noted that the first guide member 210 is a guide frame extending in the vertical direction, and the first driving member is an electric cylinder or a servo motor.

[0039] It should be understood that accurate vertical movement is particularly important for welding of large diameter or thick-walled steel pipes, because these types of pipes are more likely to have uneven docking during welding. Therefore, the first drive member drives the first mounting assembly 220 to drive the welding gun 230 to rise and fall in the operating space 120, so that the movement of the welding gun 230 in the vertical direction is adjustable and more accurate, making the welding process more stable and consistent, thereby ensuring the quality and continuity of the weld. The first drive member makes the movement of the welding gun 230 automatic, reducing the need for manual adjustment and the related time consumption, and the first drive member can adjust the position of the welding gun 230 according to the specific requirements of the welding task, speeding up the production speed and reducing the labor intensity of the operator. In addition, since the operation of the welding gun 230 can be completely controlled by the first drive member, the number of times the operator needs to directly contact the high-temperature welding area is reduced, thereby improving the safety of the operation. At the same time, the automated control system reduces the risk of welding defects and safety accidents caused by improper human operation. The first guide member 210 and the first drive member have simple structures, are not only stable but also easy to maintain, making it easier to replace or maintain the welding gun 230 and the first drive member, thereby reducing maintenance costs and possible production downtime.

[0040] For more details, please refer to Figure 3 In an embodiment of the utility model, the first mounting assembly 220 includes a first hollow rod 221, a first connecting rod 222 and a first wire tube 223. The first hollow rod 221 extends vertically, and the first hollow rod 221 is sleeved on the first wire tube 223. The welding gun 230 is electrically connected to an external welding system through the first wire tube 223. The first hollow rod 221 is vertically slidably mounted on the first guide member 210 through the first connecting rod 222, and the first driving member is connected to the first connecting rod 222.

[0041] It should be noted that the welding system is prior art.

[0042] It should be understood that the first hollow rod 221 is sleeved outside the first wire tube 223, which can not only protect the first wire tube 223, but also provide support for the first wire tube 223 to prevent the first wire tube 223 from being separated from the welding gun 230 when the welding gun 230 is raised and lowered in the operating space 120. Specifically, the combination of the first hollow rod 221 and the first wire tube 223 plays a role in protecting the internal circuit, preventing the circuit from being damaged due to external factors such as temperature and wear during the welding process, which helps to reduce maintenance requirements and extend the service life of the equipment. The first driving member is directly connected to the first connecting rod 222, so that the response of the driving system is more direct and accurate, the delay in the driving system is reduced, and the movement of the welding gun 230 is more accurate, thereby further improving the welding quality. The simple and effective first mounting assembly 220 reduces the use of complex components, reduces the failure rate and maintenance difficulty. In addition, the simplified design also facilitates rapid assembly and disassembly, and improves the flexible adjustment capability of the production line.

[0043] There are many ways to implement the flux recovery mechanism 300. Figure 1In an embodiment of the utility model, the flux recovery mechanism 300 includes a second guide member 310, a second driving member, a second mounting assembly 320 and a flux recovery device 330. The second guide member 310 is spaced apart from the first guide member 210. The second guide member 310 is mounted on the mounting platform 110. The flux recovery device 330 is vertically slidably mounted on the second guide member 310 through the second mounting assembly 320. The second driving member is mounted on the second guide member 310. The second driving member is connected to the second mounting assembly 320 and is used to drive the second mounting assembly 320 to drive the flux recovery device 330 to rise and fall in the operating space 120. The flux recovery mechanism 300, through the cooperation of the second guide member 310 and the second drive member, enables the flux recovery device 330 to move precisely in the vertical direction, effectively collects and recovers the flux scattered and unused during the welding process, which not only reduces the waste of flux, but also reduces the pollution to the environment, while reducing the cost of purchasing new flux. The effective recovery and reuse of flux reduces the demand for flux replenishment on the production line, reduces the frequency and time of production interruptions, and this automated flux recovery process makes production more continuous and smooth, improving the overall production efficiency. The connection between the second drive member and the second mounting assembly 320 ensures that the flux recovery device 330 can be accurately raised and lowered. This precise control helps to better capture and recover the flux, ensuring that the recovery efficiency of the flux is maximized. In addition, the automated recovery process also reduces the dependence on operators and reduces labor costs.

[0044] For details, please refer to Figure 3 In the embodiment of the utility model, the second mounting assembly 320 includes a second hollow rod 321, a second connecting rod 322 and a second wire tube 323. The second hollow rod 321 extends vertically, and the second hollow rod 321 is sleeved on the second wire tube 323. The second hollow rod 321 is slidably mounted on the second guide member 310 vertically through the second connecting rod 322, and the second driving member is connected to the second connecting rod 322. Similarly to the first mounting assembly 220, the structure of the second mounting assembly 320 also plays a role in protecting the internal circuit, reducing the possibility of the circuit being affected by the external environment, helping to extend the service life of the flux recovery mechanism 300 and reduce maintenance costs. The second connecting rod 322 connects the second hollow rod 321 and the second guide member 310, ensuring the movement stability of the flux recovery device 330 during the welding process, ensuring the normal operation of the flux recovery device 330, and reducing the possibility of a decrease in flux recovery efficiency due to unstable movement.

[0045] More specifically, see Figure 4In an embodiment of the utility model, the flux recovery device 330 includes a suction nozzle 331 and an air pump 332. The air pump 332 is arranged on the mounting platform 110. The suction nozzle 331 is installed at the bottom end of the second hollow rod 321. The suction nozzle 331 is arranged in the operating space 120. The suction nozzle 331 is connected to the air pump 332 through the second wire tube 323, and the suction nozzle 331 forms a flux recovery end.

[0046] It should be noted that the flux recovery device 330 is a prior art, and in the embodiment of the utility model, only the suction nozzle 331 is improved.

[0047] It should be understood that the suction nozzle 331 is a strip-shaped structure, and the suction nozzle 331 extends radially along the steel pipe. An air passage is formed inside the suction nozzle 331, and a first opening is formed at the bottom of the suction nozzle 331, and a second opening is formed on the side of the suction nozzle 331 facing the welding mechanism 200. The second opening is arched from the first opening toward the direction close to the mounting platform 110 to form an arc structure, so that the suction nozzle 331 has a strong directionality and a wider adsorption area, so as to improve the flux recovery rate of the flux recovery device 330 and improve the flux recovery effect.

[0048] Please continue to refer to Figure 3 In the embodiment of the utility model, the flux recovery mechanism 300 further includes a roller 340 and a pipe rack 350. The pipe rack 350 is spaced apart from the second guide member 310. The roller 340 is rotatably mounted on the pipe rack 350. The pipe body of the second wire tube 323 is placed on the roller 340. Specifically, in order to prevent the second wire tube 323 from being entangled with the second guide member 310 or the first guide member 210 when the suction nozzle 331 is lifted and lowered in the operation space 120, the roller 340 is used to guide the displacement of the second wire tube 323, so as to prevent the second wire tube 323 from contacting the first guide member 210 and the second guide member 310, thereby ensuring the normal operation of the flux recovery mechanism 300 and the welding mechanism 200.

[0049] There are many ways to implement the bracket 100. Figure 2 In the embodiment of the utility model, the bracket 100 includes a base 101, a stand 102 and a support plate 103. The stand 102 extends vertically, and the support plate 103 extends horizontally to form a mounting platform 110. The bottom end of the stand 102 is mounted on the base 101, and the support plate 103 is mounted on the stand 102. The combination of the base 101, the stand 102 and the support plate 103 constitutes a stable bracket 100 structure, which provides reliable support for the welding mechanism 200 and the flux recovery mechanism 300, improves the stability of the welding mechanism 200 and the flux recovery mechanism 300 during movement, and the reasonable layout of the welding mechanism 200 and the flux recovery mechanism 300 ensures the effective use of the operating space 120, and maximizes the production efficiency and the convenience of operation.

[0050] In the embodiment of the utility model, the steel pipe outer straight seam welding platform further includes a lateral displacement device, and the welding mechanism 200 and the flux recovery mechanism 300 are both connected to the lateral displacement device.

[0051] It should be noted that the lateral displacement device is a prior art.

[0052] It should be understood that the lateral displacement device includes a lateral guide member and a lateral drive member, the welding mechanism 200 is installed on the lateral guide member through a first sliding member, the flux recovery mechanism 300 is installed on the lateral guide member through a second sliding member, and the lateral drive member is connected to the first sliding member and the second sliding member respectively through an adapter, and is used to drive the first sliding member and the second sliding member to move synchronously along the radial direction of the steel pipe, so as to drive the welding mechanism 200 and the flux recovery mechanism 300 to move synchronously along the radial direction of the steel pipe, so as to adjust the positions of the welding mechanism 200 and the flux recovery mechanism 300 relative to the outer straight seam of the steel pipe, and increase the adaptability of the outer straight seam welding platform of the steel pipe to the outer straight seam welding process of the steel pipe.

[0053] In the embodiments of the present invention, please continue to refer to Figure 2 The steel pipe outer straight seam welding platform also includes a laser positioning system 400, which is installed on the installation platform 110. The positioning end of the laser positioning system 400 is arranged in the operating space 120, and the welding mechanism 200 and the flux recovery mechanism 300 are both electrically connected to the laser positioning system 400.

[0054] It should be noted that the laser positioning system 400 is a prior art.

[0055] It should be understood that the laser positioning system 400 is used to measure the distance between the top wall of the steel pipe entering the operating space 120 and the installation platform 110 and generate a control signal. The welding end of the welding mechanism 200 and the flux recovery end of the flux recovery mechanism 300 rise and fall in the operating space 120 according to the control signal to adapt to the outer diameter of the steel pipe, so as to improve the welding quality and production efficiency of the outer straight seam of the steel pipe.
