[0053] The technical solutions of the present application will be further described below with reference to specific embodiments and the accompanying drawings.

[0054] Please refer to Figure 1 , the present utility model provides a welding device 1, including a sleeve 11, a moving component 12, a first welding torch 131 and a second welding torch 132. The sleeve 11 is used to sleeved on a pipeline. The moving component 12 is slidably arranged on the sleeve 11 and can move along the circumferential direction of the sleeve 11. The first welding torch 131 is connected to the moving component 12, the second welding torch 132 is connected to the moving component 12, and the second welding torch 132 and the first welding torch 131 are arranged at intervals in the circumferential direction of the sleeve 11. Among them, the first welding torch 131 and the second welding torch 132 are configured to be driven by the moving component 12 to move along the circumferential direction of the sleeve 11 and weld the same weld to be welded successively.

[0055] The welding device 1 provided by the embodiments of the present application is applicable to welding prestressed pipes with butt - jointed end faces, and can also be applicable to welding other pipelines, which is not limited herein. Therefore, the embodiments of the present application take welding prestressed pipes with butt - jointed end faces as an example.

[0056] Among them, a pipe is sleeved on the inner wall of the sleeve 11, and the moving assembly 12 is slidably arranged on the outer wall of the sleeve 11. Please refer to Figure 2 . Both the first welding torch 131 and the second welding torch 132 are connected to a welding machine 2 and a gas source 3.

[0057] The working principle of this embodiment is as follows: two prestressed pipes are placed vertically, and the end faces of the two prestressed pipes are butted to form a weld to be welded. The sleeve 11 is sleeved on the outer wall of one of the prestressed pipes; the moving assembly 12 moves along the circumferential direction of the sleeve 11, so as to drive the first welding torch 131 and the second welding torch 132 to move along the circumferential direction of the sleeve 11 and weld the same weld to be welded successively.

[0058] It should be noted that welding the same weld to be welded successively means that the first welding torch welds the weld to be welded first, and the second welding torch welds the weld to be welded later. Specifically, the first welding torch 131, as a backing welding torch, first welds the weld to be welded to form a preliminary weld, and the second welding torch 132, as a capping welding torch, then welds the preliminary weld to complete the welding operation.

[0059] In addition, the muzzle of the first welding torch 131 is inclined relative to the radial direction of the sleeve 11 and can form an angle of about 5°, while the muzzle of the second welding torch 132 is substantially parallel to the radial direction of the sleeve 11.

[0060] In this application, the moving assembly 12 drives the first welding torch 131 and the second welding torch 132 to move, so as to weld the weld to be welded successively, thereby realizing automatic welding, improving the welding efficiency, and ensuring the welding quality at the same time.

[0061] In some embodiments, the moving assembly 12 is magnetically attracted to the sleeve 11.

[0062] In this embodiment, the moving assembly 12 is magnetically attracted to the sleeve 11, which can facilitate installation and disassembly and improve the assembly efficiency. At the same time, the moving assembly 12 being magnetically attracted to the sleeve 11 enables the moving assembly 12 and the sleeve 11 to have a certain positioning ability, and can prevent the moving assembly 12 from shifting under the action of gravity or other factors.

[0063] In some other embodiments, the moving assembly 12 can also be slidably connected to the sleeve 11.

[0064] Please refer to Figure 1 and Figure 3 . In some embodiments, the moving assembly 12 includes a moving platform 121 and moving wheels 122. Both the first welding torch 131 and the second welding torch 132 are arranged on the moving platform 121. The moving wheels 122 are rotatably arranged on the moving platform 121, and the moving wheels 122 are magnetically attracted to the sleeve 11 and can roll along the circumferential direction of the sleeve 11.

[0065] Among them, the moving wheels 122 can be permanent magnets.

[0066] In this embodiment, the moving wheel 122 can roll along the sleeve 11, reducing the friction between the moving wheel 122 and the sleeve 11, making the rolling of the moving wheel 122 smoother, and at the same time extending the service life of the moving wheel 122 and the sleeve 11.

[0067] In some other embodiments, the moving wheel 122 can also slide circumferentially along the sleeve 11.

[0068] Please refer to Figure 3 , in some more specific embodiments, a track 111 extending circumferentially along the sleeve 11 is provided on the outer wall of the sleeve 11, and the moving wheel 122 is magnetically attracted to the track 111.

[0069] Among them, the track 111 can be a steel track 111 or other metal materials with magnetism or capable of being magnetically attracted, which is not limited herein.

[0070] The moving wheel 122 is magnetically attracted to the track 111 and can roll along the extending direction of the track 111. The track 111 can limit the moving wheel 122 to only roll circumferentially along the sleeve 11, preventing the moving wheel 122 from rolling in other directions.

[0071] In some other more specific embodiments, the moving wheel 122 can be magnetically attracted to the outer wall of the entire sleeve 11.

[0072] Please refer to Figure 1 and Figure 2 , in some embodiments, the welding device 1 further includes a swinging assembly 14 and a driving member 15. The swinging assembly 14 is connected to the moving assembly 12 and is located on one side of the moving assembly 12 in the axial direction of the sleeve 11. The first welding torch 131 and the second welding torch 132 are connected to the swinging assembly 14. The driving member 15 is electrically connected to the swinging assembly 14 and can drive the swinging assembly 14 to drive the moving assembly 12 to move circumferentially along the sleeve 11.

[0073] The driving member 15 can drive the swinging assembly 14 to move circumferentially along the sleeve 11, thereby driving the moving assembly 12 to move circumferentially along the sleeve 11. Among them, the driving member 15 can have a driving effect similar to that of a stepping motor.

[0074] By driving the swinging assembly 14 by the driving member 15 to drive the moving assembly 12 to move, the control of the moving speed of the moving assembly 12 can be improved, and thus the position of the moving assembly 12 can be accurately controlled.

[0075] In some other embodiments, the driving member 15 can also be directly electrically connected to the moving assembly 12.

[0076] Please refer to again Figure 1, in some more specific embodiments, the swinging assembly 14 includes a first swinging member 141 and a second swinging member 142. Both the first swinging member 141 and the second swinging member 142 are connected to the moving assembly 12, and both the first swinging member 141 and the second swinging member 142 are electrically connected to the driving member 15. The first swinging member 141 and the second swinging member 142 are spaced apart in the circumferential direction of the sleeve 11, and the first welding torch 131 is connected to the first swinging member 141, and the second welding torch 132 is connected to the second swinging member 142. Wherein, the driving member 15 is configured to drive the first swinging member 141 to drive the moving assembly 12 to move along the circumferential direction of the sleeve 11, or drive the second swinging member 142 to drive the moving assembly 12 to move in the reverse direction along the circumferential direction of the sleeve 11.

[0077] When it is necessary to move forward along the circumferential direction of the sleeve 11, the two prestressed pipes are placed vertically, and the end faces of the two prestressed pipes are butted to form a weld to be formed. The sleeve 11 is sleeved on the outer wall of one of the prestressed pipes. The driving member 15 drives the first swinging member 141 to drive the moving assembly 12 to move forward along the circumferential direction of the sleeve 11, so as to drive the first welding torch 131 and the second welding torch 132 to move along the circumferential direction of the sleeve 11 and weld the same weld to be formed successively.

[0078] When it is necessary to move in the reverse direction along the circumferential direction of the sleeve 11, the two prestressed pipes are placed vertically, and the end faces of the two prestressed pipes are butted to form a weld to be formed. The sleeve 11 is sleeved on the outer wall of one of the prestressed pipes. The driving member 15 drives the second swinging member 142 to drive the moving assembly 12 to move in the reverse direction along the circumferential direction of the sleeve 11, so as to drive the first welding torch 131 and the second welding torch 132 to move along the circumferential direction of the sleeve 11 and weld the same weld to be formed successively.

[0079] In the embodiment of the present application, the first swinging member 141 or the second swinging member 142 drives the moving assembly 12 to move forward or backward respectively along the circumferential direction of the sleeve 11, so that it can move forward or backward according to the welding requirements, improving the flexibility of welding.

[0080] In some other more specific embodiments, the driving member 15 is configured to drive the first swinging member 141 to drive the moving assembly 12 to move bidirectionally along the circumferential direction of the sleeve 11.

[0081] Please continue to refer to Figure 1 , in some more specific embodiments, the welding device 1 further includes a first clamping member 161 and a second clamping member 162. The first clamping member 161 is connected to the side of the first swinging member 141 away from the moving assembly 12, and the first clamping member 161 clamps the first swinging member 141. The second clamping member 162 is connected to the side of the second swinging member 142 away from the moving assembly 12, and the second clamping member 162 clamps the second swinging member 142.

[0082] By setting the first clamping member 161 to clamp the first welding torch 131, it is possible to prevent the first welding torch 131 from jittering during welding, ensuring the stability of the first welding torch 131 during the welding process to guarantee the welding accuracy of the first welding torch 131. Similarly, by setting the second clamping member 162 to clamp the second welding torch 132, it is possible to prevent the second welding torch 132 from jittering during welding, ensuring the stability of the second welding torch 132 during the welding process to guarantee the welding accuracy of the second welding torch 132.

[0083] In some other more specific embodiments, the first welding torch 131 and the second welding torch 132 can be clamped by the same clamping member.

[0084] In some more specific embodiments, the welding device 1 further includes a first sliding table 171 and a second sliding table 172. The first sliding table 171 is connected to the moving assembly 12, and the first swinging member 141 is slidably connected to the first sliding table 171 and can selectively approach or move away from the pipeline. The second sliding table 172 is connected to the moving assembly 12, and the second swinging member 142 is slidably connected to the second sliding table 172 and can selectively approach or move away from the pipeline.

[0085] By slidably connecting the first swinging member 141 to the first sliding table 171, when the distance between the first welding torch 131 and the pipeline is relatively far, the first swinging member 141 can slide closer to the pipeline to adjust the first welding torch 131 to a proper position; when the distance between the first welding torch 131 and the pipeline is too close, the first swinging member 141 can slide and move away from the pipeline to adjust the first welding torch 131 to a proper position.

[0086] Similarly, by slidably connecting the second swinging member 142 to the second sliding table 172, when the distance between the second welding torch 132 and the pipeline is relatively far, the second swinging member 142 can slide closer to the pipeline to adjust the second welding torch 132 to a proper position; when the distance between the second welding torch 132 and the pipeline is too close, the second swinging member 142 can slide and move away from the pipeline to adjust the second welding torch 132 to a proper position.

[0087] The first sliding table 171 can adjust the first swinging member 141 to approach or move away from the pipeline, thereby adjusting the position of the first welding torch 131 and guaranteeing the welding accuracy of the first welding torch 131. Similarly, the second sliding table 172 can adjust the second swinging member 142 to approach or move away from the pipeline, thereby adjusting the position of the second welding torch 132 and guaranteeing the welding accuracy of the second welding torch 132.

[0088] In some more specific embodiments, the first swinging member 141 and the second swinging member 142 can be slidably arranged on the same sliding table.

[0089] In some more specific embodiments, the welding device 1 further includes a first adjusting member 181 and a second adjusting member 182. The first adjusting member 181 is connected to the moving assembly 12. The first adjusting member 181 is connected to the first swinging member 141 and can adjust the position of the first swinging member 141 in the axial direction of the sleeve 11. The second adjusting member 182 is connected to the moving assembly 12. The second adjusting member 182 is connected to the second swinging member 142 and can adjust the position of the second swinging member 142 in the axial direction of the sleeve 11.

[0090] By slidably connecting the first swinging member 141 to the first adjusting member 181, when the distance between the first welding torch 131 and the weld to be made in the axial direction of the pipeline is large, the first adjusting member 181 can adjust the position of the first swinging member 141 in the axial direction of the pipeline, so as to adjust the first welding torch 131 to a suitable position.

[0091] Similarly, by slidably connecting the second swinging member 142 to the second adjusting member 182, when the distance between the second welding torch 132 and the weld to be made in the axial direction of the pipeline is large, the second adjusting member 182 can adjust the position of the second swinging member 142 in the axial direction of the pipeline, so as to adjust the second welding torch 132 to a suitable position.

[0092] By adjusting the first swinging member 141 through the first adjusting member 181 and adjusting the second swinging member 142 through the second adjusting member 182, the first welding torch 131 and the second welding torch 132 can be adjusted to suitable positions in the axial direction of the pipeline, which can improve the welding precision of the first welding torch 131 and the second welding torch 132.

[0093] In some other more specific embodiments, the first swinging member 141 and the second swinging member 142 can both be connected to the same adjusting member.

[0094] In some embodiments, the welding device 1 further includes a chain 19. The chain 19 is connected to the moving assembly 12 and sleeved on the sleeve 11 to fasten the moving assembly 12.

[0095] By providing the chain 19 to connect the moving assembly 12, the moving assembly 12 can be prevented from accidentally detaching from the sleeve 11 during the welding process, which improves the stability and reliability of the welding device 1.

[0096] In some other embodiments, the moving assembly 12 can also be connected by other connecting members such as a belt.

[0097] Although the present utility model has been described with reference to the preferred embodiments, various modifications thereof can be made and components thereof can be replaced with equivalents without departing from the scope of the present utility model.
