[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0037] like Figure 1-Figure 2 As shown, the present invention employs the following technical solution: a large steel structure building component comprises a plurality of steel tubes 7, adjacent steel tubes 7 being coaxially welded and fixed. Each steel tube 7 has a spiral groove 25 formed therein, with the spiral grooves 25 in two adjacent steel tubes 7 running in opposite directions. When concrete is poured into the steel tubes 7, the concrete enters the spiral grooves 25, preventing the concrete from moving relative to the steel tubes 7 and thereby improving the supporting strength of the steel tubes 7.

[0038] like Figure 3-Figure 12 As shown, a large-scale steel structure building component welding process in the present invention includes the following steps: S1, making the steel pipes 7 on the second conveyor belts 23 on both sides of the first conveyor belt 22 correspond to the corresponding sleeves 8, the second conveyor belt 23 is used to convey the steel pipes 7 to be welded, and the first conveyor belt 22 is used to convey the welded steel pipes 7.

[0039] S2. Start the first driving assembly to move the sleeve 8 outward and extend into the steel pipe 7, and start the positioning support assembly to fix the steel pipe 7 and the sleeve 8 in connection.

[0040] S3. Start the second driving assembly to rotate the sleeve 8 horizontally, and then use the first driving assembly to move the two sleeves 8 closer to each other, so that the two steel pipes 7 are docked.

[0041] S4. Start the third driving assembly to rotate the sleeve 8 around the connecting rod 15 and approach the welding gun 6. The fourth driving assembly is used to make the two sleeves 8 rotate synchronously, and the welding gun 6 welds the steel pipe 7.

[0042] S5. After welding is completed, the sleeve 8 is rotated around the connecting rod 15 by the third driving assembly to approach the first conveyor belt 22.

[0043] S6. Release the limit of the positioning support assembly on the welded steel pipe 7, and then move the sleeve 8 outward through the first drive assembly. The sleeve 8 is separated from the welded steel pipe 7 and extends into the next steel pipe 7 to be welded.

[0044] A support frame 4 is fixedly mounted across the first conveyor belt 22, and a welding gun 6 is disposed at the top of the support frame 4. Fixed seats 14 are rotatably mounted on both sides of the support frame 4. The third drive assembly drives the fixed seats 14 to rotate. Specifically, the third drive assembly includes a third motor 5 fixedly mounted on the support frame 4. The motor shaft of the third motor 5 is horizontally arranged and fixedly connected to one of the fixed seats 14. The two fixed seats 14 are fixedly connected by a connecting rod 15. When the third motor 5 is started, the two fixed seats 14 rotate synchronously. The axis of the connecting rod 15 is on the same horizontal line as the motor shaft of the third motor 5.

[0045] Each fixing base 14 is rotatably connected to a connecting base 12 on both its upper and lower sides. A second drive assembly is disposed between each fixing base 14 and the connecting base 12. The second drive assembly includes a second motor 16, which is embedded and fixedly mounted within the fixing base 14. The motor shaft of the second motor 16 is vertically disposed and fixedly connected to the corresponding connecting base 12.

[0046] A connecting sleeve 10 is rotatably connected in each connecting seat 12. A fourth drive assembly is provided on each connecting seat 12 to drive the corresponding connecting sleeve 10 to rotate. Specifically, the fourth drive assembly includes a fourth motor 20, a second gear 13 and a third gear 11. A mounting hole is provided on the connecting seat 12, and one end of the connecting sleeve 10 is rotatably mounted in the mounting hole. The fourth motor 20 is embedded and fixedly mounted in the connecting seat 12, and the second gear 13 is coaxially fixedly mounted on the motor shaft of the fourth motor 20. The third gear 11 is coaxially fixedly set at the end of the connecting sleeve 10, and the third gear 11 and the second gear 13 are engaged. When the welding gun 6 is welding, the fourth motor 20 is started, the second gear 13 rotates, the connecting sleeve 10 rotates, the sleeve 8 rotates, and the steel pipe 7 rotates synchronously, so that the welding gun 6 performs comprehensive welding on the steel pipe 7.

[0047] Each connecting sleeve 10 is slidably connected to a sleeve 8. A first drive assembly, which drives the sleeve 8, is mounted within the connecting sleeve 10. The first drive assembly comprises a first motor 18, a first gear 17, and a rack 24. The first motor 18 is embedded and fixedly mounted within the connecting sleeve 10. The first gear 17 is coaxially fixedly mounted on the motor shaft of the first motor 18. The first gear 17 meshes with the rack 24, which is arranged axially along the sleeve 8 and fixedly connected to the sleeve 8. When the first motor 18 is activated, the first gear 17 rotates, causing the sleeve 8 to slide along the connecting sleeve 10.

[0048] The sleeve 8 is provided with a positioning support assembly. When the sleeve 8 is inserted into the steel pipe 7, the positioning support assembly fixes the steel pipe 7 and the sleeve 8 coaxially. The positioning support assembly includes an electric push rod 21 and a top plate 9. A fixed sleeve 19 is coaxially fixedly installed in the sleeve 8. A plurality of top plates 9 are evenly distributed on the circumference of the sleeve 8. The top plates 9 and the fixed sleeve 19 are fixedly connected by the electric push rod 21. A clearance hole is provided on the circumferential surface of the sleeve 8 at a position corresponding to the top plate 9. When the electric push rod 21 is activated, the top plate 9 moves away from the fixed sleeve 19, and then the top plate 9 is pressed against the inner wall of the steel pipe 7. The steel pipe 7 and the sleeve 8 are coaxially fixed by the plurality of top plates 9.

[0049] A material receiving plate 3 is provided on the first conveyor belt 22 . A V-shaped groove for limiting the position of the steel pipe 7 is provided on the material receiving plate 3 , and a rubber layer is provided in the V-shaped groove.

[0050] A positioning plate 1 is provided on the second conveyor belt 23 , and a positioning groove 2 for limiting the position of the steel pipe 7 is provided on the positioning plate 1 .

[0051] During use, the two steel pipes 7 to be welded are placed on the two second conveyor belts 23 respectively, and the steel pipes 7 correspond to the adjacent sleeves 8. At this time, the axis of the steel pipe 7 is lower than the axis of the sleeve 8 below the connecting rod 15.

[0052] At the lower part of the support frame 4: start the first motor 18 below the fixed seat 14, the first gear 17 rotates, and the corresponding sleeve 8 moves toward the direction close to the steel pipe 7, and then the sleeve 8 gradually extends into the adjacent steel pipe 7. When the sleeve 8 extends into the steel pipe 7 to a certain distance, turn off the first motor 18. Start the electric push rod 21, and move the top plate 9 away from the fixed sleeve 19, so that multiple top plates 9 are all against the inner wall of the steel pipe 7, and the steel pipe 7 and the sleeve 8 are coaxially fixed. Since the axis of the steel pipe 7 is lower than the axis of the sleeve 8 when the sleeve 8 is initially inserted into the steel pipe 7, when the top plate 9 moves close to the inner wall of the steel pipe 7, the top plate 9 will drive the steel pipe 7 to move upward, thereby separating the steel pipe 7 from the positioning plate 1 and placing the steel pipe 7 a certain distance above the positioning plate 1.

[0053] Then, the second motor 16 below the fixed seat 14 is started, which drives the connecting seat 12 below the fixed seat 14 to rotate. The connecting sleeve 10, sleeve 8, and steel pipe 7 rotate synchronously, causing the steel pipe 7 to rotate 180 degrees around the axis of the second motor 16, thereby moving the steel pipe 7 to the inside of the support frame 4. At this time, the two steel pipes 7 are on the same straight line, but there is a gap between them. The first motor 18 below the fixed seat 14 is started, which drives the two sleeves 8 on the lower side of the connecting rod 15 closer to each other until the two steel pipes 7 are docked, thus completing the loading process.

[0054] Then, the third motor 5 is started, and the fixing base 14 rotates, causing the connecting base 12, the sleeve 8, and the steel pipe 7 to rotate 180 degrees around the axis of the third motor 5, and the steel pipe 7 moves to the top of the connecting rod 15. Above the connecting rod 15: the corresponding fourth motor 20 is started, the connecting sleeve 10 rotates, and the sleeve 8 drives the steel pipe 7 to rotate. The two steel pipes 7 rotate synchronously, and the welding gun 6 welds the steel pipes 7, so that the two steel pipes 7 are welded and fixed.

[0055] At the same time, below the connecting rod 15, the next steel pipe 7 to be welded is moved to a position corresponding to the sleeve 8 by the second conveyor belt 23. Afterwards, the steel pipe 7 to be welded is transported to the inner side of the support frame 4 through the sleeve 8, and the two steel pipes 7 are docked.

[0056] When the welding of the steel pipe 7 above the connecting rod 15 is completed, the third motor 5 is started again to flip the fixing seat 14 180 degrees, so that the welded steel pipe 7 is below the connecting rod 15 and close to the first conveyor belt 22, and the steel pipe 7 to be welded is above the connecting rod 15 and close to the welding gun 6.

[0057] Above the connecting rod 15 : the welding gun 6 welds the corresponding steel pipe 7 .

[0058] Below the connecting rod 15, the second conveyor belt 23 moves the next steel pipe 7 to be welded to the corresponding position with the sleeve 8. The electric push rod 21 is activated, causing the top plate 9 to move closer to the fixed sleeve 19, thereby releasing the limit on the steel pipe 7. The first drive assembly causes the sleeve 8 to move outward, removing the sleeve 8 from the welded steel pipe 7 and extending into the steel pipe 7 on the second conveyor belt 23. After losing the support of the sleeve 8, the welded steel pipe 7 falls onto the corresponding receiving plate 3. The first conveyor belt 22 moves, removing the welded steel pipe 7 and allowing the next receiving plate 3 to move below the support frame 4.

[0059] While the welding gun 6 is welding the steel pipe 7 above the connecting rod 15, the sleeve 8 below the connecting rod 15 moves outward, allowing the welded steel pipe 7 to fall onto the first conveyor belt 22, completing unloading. The sleeve 8 then moves outward and extends into the next steel pipe 7 to be welded, completing loading. Thus, welding, unloading, and loading are performed simultaneously, improving the level of welding automation, thereby increasing welding production efficiency, and simplifying the structure and process flow.

[0060] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
