The clamping assembly 20 is provided with two groups, and the two groups of clamping assemblies 20 are slidingly arranged on the upper part of the welding table 10 and are oppositely distributed, and are used for clamping two steel pipes respectively. The driving assembly 60 is installed below the welding table 10 and is used for driving the two groups of clamping assemblies 20 to move towards each other. The support ring 30 is arranged between the two groups of clamping assemblies 20, and the support ring 30 is movably installed on the upper part of the welding table 10. The rotary welding assembly 40 is rotatably arranged on the inner wall of the support ring 30 and is used for circumferentially welding the two steel pipes. The adjusting assembly 50 is arranged on the inner side of the support ring 30. When the driving assembly 60 drives the two groups of clamping assemblies 20 to move towards each other, the adjusting assembly 50 is used for adjusting the angle of the support ring 30, so that the rotation track of the rotary welding assembly 40 is consistent with the welding seam trend of the two steel pipes.

[0036] When two building steel pipes need to be welded together, two sets of clamping assemblies 20 can clamp the two steel pipes respectively, and then the driving assembly 60 drives the two sets of clamping assemblies 20 to move towards each other, and when the two sets of clamping assemblies 20 move towards each other, they drive the two steel pipes to move towards each other. At the same time, the adjusting assembly 50 adjusts the angle of the support ring 30, and when the ends of the two steel pipes that need to be welded extend into the inside of the support ring 30, the adjusting assembly 50 completes the angle adjustment of the support ring 30, and then the rotary welding assembly 40 rotates around the two steel pipes for one revolution. At this time, through the adjusting action of the adjusting assembly 50 on the support ring 30, the rotation track of the rotary welding assembly 40 can be consistent with the welding seam trend of the two steel pipes, so that the two steel pipes can be successfully welded together.

[0037] Please refer to Figure 1 In one embodiment, the welding table 10 is provided with a sliding groove 101, and the two sets of clamping assemblies 20 are identical in structure and each include a sleeve 201, a first locking screw 202, and a sliding rod 203. The first locking screw 202 is threadedly arranged on the side wall of the sleeve 201, and the sliding rod 203 is fixedly connected to one end of the sleeve 201 and extends from the sliding groove 101 to below the welding table 10.

[0038] Two steel pipes are respectively inserted from the inside of the sleeves 201 of the two sets of clamping assemblies 20, and then the first locking screws 202 on the side walls of the two sleeves 201 are twisted to rotate the two first locking screws 202 into the inside of the corresponding sleeves 201, thereby supporting the two steel pipes on the inner walls of the two sleeves 201, so as to clamp the two steel pipes. Subsequently, the second motor 601 is started to drive the rotating shaft 602 to rotate. When the rotating shaft 602 rotates, the two sets of thread segments 603 threadedly engage with the two sets of sliding rods 203 to drive the two sets of sliding rods 203 to slide towards each other inside the sliding groove 101, and the two sets of sliding rods 203 drive the two sets of sleeves 201 and the two steel pipes clamped in the two sets of sleeves 201 to move towards each other.

[0039] Please refer to Figure 1 In one embodiment, the welding table 10 is provided with a sliding rail 102 fixedly arranged at the upper portion, and the side walls of the sliding rods 203 of the two sets of clamping assemblies 20 are each fixedly provided with a sliding block 204 that slidably engages with the sliding rail 102.

[0040] Through the sliding cooperation of the sliding block 204 and the sliding rail 102, the stability of the two groups of sliding rods 203 and the two groups of sleeves 201 when moving towards each other can be improved, and then the stability of the two steel pipes when moving towards each other can be improved.

[0041] Please refer to Figure 1 and Figure 3 In one embodiment, the bottom of the support ring 30 is fixedly provided with a rotating disc 302 through a stand 301, the rotating disc 302 is rotationally arranged on the upper portion of a base 303, the rotating welding assembly 40 comprises a welding gun 401, a rotating ring 402 and a power component, the rotating ring 402 is rotationally arranged on the inner wall of the support ring 30, the welding gun 401 is fixedly arranged on the inner wall of the rotating ring 402, the power component is installed on the upper portion of the rotating disc 302, and is used to drive the rotating ring 402 to rotate relative to the inner wall of the support ring 30, the adjusting assembly 50 comprises a pressing plate 501, a lifting seat 502, a guide rod 503 and a spring 504, the guide rod 503 is fixedly arranged on the inner wall of the rotating ring 402, the lifting seat 502 is movably sleeved on the outside of the guide rod 503, the pressing plate 501 is fixedly arranged on the upper portion of the lifting seat 502, one end of the spring 504 is connected with the inner wall of the rotating ring 402, and the other end of the spring 504 is connected with the lifting seat 502, and the spring 504 is used to elastically support the lifting seat 502.

[0042] When the two sets of sleeves 201 drive the two steel pipes to move towards each other, the welded ends of the two steel pipes extend into the inside of the support ring 30 and act on the opposite sides of the pressing plate 501. At this time, if the vertical plane in which the support ring 30 and the rotating ring 402 are located is parallel to the welded end faces of the two steel pipes, the welded surfaces between the two steel pipes are in full contact with the opposite sides of the pressing plate 501, and the support ring 30 and the rotating ring 402 remain stationary. At this time, the worker can press the lifting seat 502 to make the lifting seat 502 move downward along the guide rod 503, the spring 504 is compressed, the lifting seat 502 drives the pressing plate 501 to move downward, and the pressing plate 501 is removed from between the two steel pipes. Then, the power component drives the rotating ring 402 to rotate relative to the inner wall of the support ring 30 by one revolution, and the rotating ring 402 drives the welding gun 401 to rotate along the welding seam between the two steel pipes by one revolution, so as to weld the two steel pipes into one.

[0043] Please refer to Figure 3 In an embodiment, the bottom of the lifting seat 502 is hingedly provided with a hook 505, and a limiting ring 403 is fixedly arranged on the inner wall of the rotating ring 402.

[0044] After pressing the lifting seat 502 to remove the pressing plate 501 from between the two steel pipes, the worker can hook the hook 505 to the limiting ring 403, so as to limit the pressing plate 501, so that the pressing plate 501 is maintained in the position removed from between the two steel pipes.

[0045] Please refer to Figure 3 and Figure 4In one embodiment, the power component comprises a gear 404, an outer gear ring 405, and a first motor 406, one end of the rotating ring 402 extends to the outside of the support ring 30 and is fixedly connected with the outer gear ring 405, the first motor 406 is fixedly arranged on the upper part of the rotating disc 302, the gear 404 is installed on the output end of the first motor 406 and is engaged with the outer gear ring 405.

[0046] After the abutting plate 501 is removed from between the two steel pipes, the first motor 406 is started, the first motor 406 drives the gear 404 to rotate, the gear 404 drives the rotating ring 402 to rotate one circle compared with the inner wall of the support ring 30 through the engagement of the gear 404 and the outer gear ring 405, and the rotating ring 402 drives the welding gun 401 to rotate one circle along the welding seam of the two steel pipes, so as to weld the two steel pipes into one.

[0047] Please refer to Figure 4 In one embodiment, the rotating disc 302 is further provided with a second locking screw 304.

[0048] After the welding surfaces of the two steel pipes are in full contact with the opposite side walls of the abutting plate 501 respectively, the support ring 30 and the rotating ring 402 complete the angle adjustment, at this time, the worker can rotate the second locking screw 304 so that the second locking screw 304 is screwed down compared with the rotating disc 302 and is supported on the base 303, thereby limiting the rotating disc 302, so as to ensure the stability of the support ring 30, so that the rotating ring 402 and the welding gun 401 can rotate smoothly, thereby improving the welding quality of the two steel pipes.

[0049] After the two steel pipes are clamped in the two sets of sleeves 201 respectively, since the distance between the two steel pipes and the support ring 30 cannot be determined, during the subsequent moving process of the two steel pipes, one of the steel pipes may first extend into the inside of the support ring 30 and act on the abutting plate 501, and the subsequent movement of the other steel pipe will be blocked, resulting in that the two steel pipes cannot be smoothly welded due to the far distance, based on this, please refer to Figure 1 In one embodiment, the base 303 is in sliding fit with the slide rail 102.

[0050] Through the sliding fit between the base 303 and the slide rail 102, when one of the steel pipes first extends into the inside of the support ring 30 and acts on the abutting plate 501, the steel pipe can push the abutting plate 501 and drive the base 303 to adaptively slide compared with the slide rail 102, the support ring 30 and the abutting plate 501 move synchronously with the steel pipe, until the other steel pipe extends into the inside of the support ring 30, the two steel pipes act on the opposite sides of the abutting plate 501 respectively, thereby ensuring that the appropriate welding distance is formed between the two steel pipes.

[0051] When two building steel pipes need to be welded together in the embodiment of the present application, two groups of clamping assemblies 20 can clamp the two steel pipes respectively, then the driving assembly 60 drives the two groups of clamping assemblies 20 to move towards each other, when the two groups of clamping assemblies 20 move towards each other, the two steel pipes are brought close to each other, at the same time, the adjusting assembly 50 adjusts the angle of the support ring 30, when the ends of the two steel pipes that need to be welded extend into the inside of the support ring 30, the adjusting assembly 50 completes the angle adjustment of the support ring 30, then the rotary welding assembly 40 rotates around the two steel pipes for one turn, at this time, through the adjusting effect of the adjusting assembly 50 on the support ring 30, the rotation track of the rotary welding assembly 40 can be consistent with the weld seam trend of the two steel pipes, so that the two steel pipes can be successfully welded together. Compared with the prior art, when the two building steel pipes are welded, the angle of the rotary welding assembly 40 can be adjusted, so that the rotation track of the rotary welding assembly 40 can be consistent with the weld seam trend of the two steel pipes, thereby ensuring the welding quality and improving the welding effect.

[0052] The preferred embodiments of the present application are described in detail above, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application.
