[0002] Steel structure connection refers to the process of connecting steel components to each other in various ways to form an overall structure in structures such as buildings, bridges, and towers. This connection method is crucial to ensuring the safety, stability, and durability of the entire structure. Steel structure connection methods include welding. Welding is a process that uses high temperatures to melt metals and combine them together. It can provide a continuous connection, help transmit greater force, and does not require additional fasteners. Therefore, the welding process is very important in the process of steel pipe butt jointing.

The present invention is provided with a limit assembly, a clamping assembly, a slide, and an electromagnetic plate. When in use, the clamping assembly can be moved inside the placement slot through the cooperation of the slide and the slide, and the distance between the clamping assembly and the limit assembly can be conveniently changed.

[0031] Working principle: Before welding the steel pipe, pass the steel pipe through the mounting plate 601, start the electric push rod 3 602, so that the output end of the electric push rod 3 602 drives the clamping block 603 to move, so that the clamping block 603 clamps the steel pipe, achieving the clamping effect of the steel pipes on both sides; First, repair the steel pipe, start the electric push rod 1 302 to make the sliding block 303 move horizontally, start the electric push rod 2 304 to make the support ring 305 move vertically to a reasonable position, until the steel pipe moves to the position of the repair knife 1004, start the adjustment motor 501, the output shaft of the adjustment motor 501 rotates to drive the adjustment rod 502 to rotate, the adjustment rod 502 rotates to drive the adjustment block 503 to rotate, the adjustment block 503 drives the mounting plate 601 to rotate the angle, so that the steel pipe is adjusted to a reasonable position, and at the same time start the rotating motor 702, the output shaft of the rotating motor 702 rotates to drive the rotating rod 703 to rotate, the rotating rod 703 drives the rotating block 704 to rotate, so that the lifting component 8, the protection component 9, the repair component 10 and the transmission component 11 rotate the angle, so that the steel pipe is in a state to be repaired; start the hydraulic lifting rod 802 so that the hydraulic lifting rod The output end of 802 drives the lifting cylinder 803 to move in the supporting outer cylinder 801, and the lifting cylinder 803 drives the mounting block 1001, the repair rod 1002, the repair motor 1003 and the repair knife 1004 to move upward. The lifting cylinder 803 moves upward, so that the transmission spur rack 1102 drives the transmission gear 1101 to rotate, and the transmission gear 1101 rotates and drives the transmission spur rack 2 1103 to move downward, forcing the transmission spur rack 2 1103 to drive the protective cover 903 to move downward. At this time, the protection spring 904 is compressed, and the supporting inner rod 902 moves in the supporting outer rod 901 to achieve the supporting effect on the protective cover 903, and the repair motor 1003 is started. The output shaft of the repair motor 1003 rotates to drive the repair rod 1002 to rotate, and the repair rod 1002 rotates to drive the repair knife 1004 to rotate, and the repair knife 1004 cuts and repairs the steel pipe; After the repair is completed, the control system will adjust the adjusting motor 501 to the welding angle according to the rotation angle of the adjusting motor 501 and the rotation angle of the rotating motor 702, so that the rotating motor 702 drives the rotating rod 703 to rotate, forcing the rotating block 704 to be in a vertical state, so that the lifting assembly 8, the protective assembly 9, the repair assembly 10 and the transmission assembly 11 are in a vertical state, and the hydraulic lifting rod 802 is started in the reverse direction. The hydraulic lifting rod 802 retreats and drives the lifting cylinder 803 to move in the supporting outer cylinder 801. The lifting cylinder 803 drives the repair assembly 10 to retreat. Under the transmission action of the transmission spur rack 1 102, the transmission gear 1101 and the transmission spur rack 2 1103, the lifting cylinder 803 retreats and drives the protective cover 903 to move upward until the repair knife 1004 and the repair motor 1003 are hidden in the protective cover 903, so that the protective cover 903 protects the repair knife 1004 and the repair motor 1003. During alignment, the electric push rod 302 is started to move the sliding block 303 forward, and the rotating assembly 4 and the adjusting assembly 5 move accordingly, forcing the clamping block 603 to drive the steel pipe forward, so that the repaired steel pipe contacts the outer side of the protective cover 903, ensuring the alignment of the repair position of the steel pipe, thereby achieving pre-alignment of the steel pipe before welding. When the steel pipe and the protective cover 903 are not aligned, the adjusting motor 501 is started to adjust the welding angle of the steel pipe until the steel pipe and the protective cover 903 are aligned; During welding, the electric push rods 302 on both sides are started to retreat, so that the steel pipes retreat to a reasonable position, so that the steel pipes on both sides are away from each other, and the rotating motor 702 is started. The rotating motor 702 drives the rotating rod 703 to rotate, and the rotating rod 703 drives the rotating block 704 to rotate to a horizontal state, forcing the lifting component 8, the repair component 10 and the protection component 9 to be in a horizontal state, ensuring the smooth welding of the steel pipes and avoiding obstruction during welding. At this time, the steel pipes on both sides are aligned, and the electric push rod 302 is started again to move forward, forcing the two steel pipes to approach each other until the heads of the two steel pipes are aligned. At this time, the effect of multi-angle alignment can be achieved; start the welding equipment 2, use the welding equipment 2 to weld the heads of the steel pipes, and start the rotating motor 402 at the same time. The output shaft of the rotating motor 402 rotates to drive the driving gear 403 to rotate, and the driving gear 403 rotates to drive the driven gear 404 to rotate. The rotation of 404 drives the rotating ring 401 to rotate, and the rotation of the rotating ring 401 drives the adjusting component 5 and the clamping component 6 to rotate, so that the clamping blocks 603 on both sides drive the two steel pipes to rotate synchronously, thereby achieving the effect of annular welding of the steel pipe. Since the sparks generated by welding cause damage to the repair knife 1004 and the repair motor 1003, the rotating component 7 rotates to a horizontal state and will be away from the welding equipment 2. At the same time, the protective cover 903 can further protect the repair knife 1004 and the repair motor 1003, thereby increasing the service life of the repair knife 1004 and the repair motor 1003; during repair, the protective cover 903 can expose the repair component 10, thereby smoothly realizing the repair effect on the steel pipe. During pre-alignment, the protective cover 903 can form an alignment effect on the steel pipe, which is beneficial to the welding of the steel pipe. During welding, the protective cover 903 can hide the repair component 10, thereby realizing the protection of the repair component 10.

[0032] This solution can realize welding scenarios at different angles, achieve multi-angle cutting and repair of steel pipes, adapt to welding in various environments, handle different welding tasks, integrate multi-angle adjustment, cutting and repair, and welding in one, occupy a small space, realize the multi-functional role of the device, improve the versatility of the device, reduce enterprise costs, improve the flexibility of the device, facilitate the mass production of various welded steel pipes, meet production needs, greatly improve production efficiency, benefit the production operation of the enterprise, and enhance the competitiveness of the enterprise.
