When the clamping plate rises, it drives the first rack to move, thereby driving the transmission gear and the clutch to rotate. The clutch drives the driving shaft, driving gear and chain to rotate, thereby driving the steel structure to move, facilitating the welding of the next rivet. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The electric switching valve 412 is a multi-channel switching valve.

[0049] The multi-channel switching valve can switch the gas sprayed by the nozzle 409 between high-temperature gas and low-temperature gas to meet the needs of different welding stages.

[0050] The photoelectric sensor 417 is a reflective photoelectric sensor.

[0051] The reflective photoelectric sensor has a relatively simple structure, small size, light weight, and is easy to install and use. At the same time, due to its non-contact characteristics, it also reduces the space restrictions and requirements during installation.

[0052] Working principle: When working, the staff puts the steel structure to be welded on the chain 306 and puts the rivets on it. Then the staff opens the second telescopic rod 208, the first telescopic rod 206 and the compressor. When the staff opens the second telescopic rod 208, the second telescopic rod 208 extends, and the extension of the second telescopic rod 208 drives the lower mold 209 and the bearing plate 210 to move upward until they contact the steel structure. When the staff opens the first telescopic rod 206, the first telescopic rod 206 extends, and the extension of the first telescopic rod 206 drives the fixed plate 203, the first spring 205, the clamping plate 204 and the upper mold 207 to move downward first, until the clamping plate 204 contacts the steel structure, and the clamping plate 204 and the bearing plate 210 play a role in fixing the steel structure. Then the upper mold 207 continues to move downward and the lower mold 209 shapes the rivet, thereby completing the hot riveting welding of the steel structure.

[0053] When the staff turns on the air compressor 410, the air compressor 410 generates high-pressure gas, which enters the island vortex tube 411 and becomes low-temperature gas and high-temperature gas. The low-temperature gas enters the cold air pipe 413, and the high-temperature gas enters the hot air pipe 414. When the clamping plate 204 moves downward, the clamping plate 204 drives the first connecting rod 309 to move downward, the first connecting rod 309 drives the second connecting rod 310 to move downward, the second connecting rod 310 drives the first rack 311 to move downward, the first rack 311 drives the transmission gear 308 to rotate, the transmission gear 308 rotates and drives the second rack 406 to move upward, the second rack 406 moves upward and drives the third rack 407 to move upward, the third rack 407 moves upward and drives the driven gear 402 to rotate, the driven gear 402 rotates and drives the rotating rod 401 to rotate, the rotating rod 401 rotates and drives the bracket 408 to rotate, the bracket 408 rotates and drives the nozzle 409 to rotate until the nozzle 409 is aligned with the steel structure being processed. When the clamping plate 204 moves downward, the clamping plate 204 will block the photoelectric sensor 417, and the photoelectric sensor 417 will open the electric switching valve 412, so that the hot air pipe 414 is connected with the intake pipe 415, and the cold air pipe 413 is connected with the exhaust pipe 416, so that the high-temperature gas enters the nozzle 409 from the intake pipe 415, and then flows out from the nozzle 409 to clean the steel structure, and at the same time, the rivets on the steel structure can be preheated.

[0054] When welding is completed, the staff opens the second telescopic rod 208 and the first telescopic rod 206. When the staff opens the second telescopic rod 208, the second telescopic rod 208 shortens, and the shortening of the second telescopic rod 208 drives the lower mold 209 and the bearing plate 210 to move downward and separate from the steel structure. When the staff opens the first telescopic rod 206, the first telescopic rod 206 shortens, and the shortening of the first telescopic rod 206 drives the fixing plate 203, the first spring 205, the clamping plate 204 and the upper mold 207 to move downward first and separate from the steel structure. When the clamping plate 204 moves upward, the clamping plate 204 drives the first connecting rod 309 to move upward, the first connecting rod 309 drives the second connecting rod 310 to move upward, the second connecting rod 310 drives the first rack 311 to move upward, the first rack 311 drives the transmission gear 308 to rotate, the transmission gear 308 rotates to drive the clutch 307 to rotate, the clutch 307 rotates to drive the driving shaft 302 to rotate, the driving shaft 302 rotates to drive the driving gear 304 to rotate, the driving gear 304 rotates to drive the chain 306 to rotate, thereby driving the steel structure to move left. When the transmission gear 308 rotates, the transmission gear 308 drives the second rack 406 to move downward, the second rack 406 moves downward, the second rack 406 moves downward and drives the third rack 407 to move downward, the third rack 407 moves downward and drives the driven gear 402 to rotate, the driven gear 402 rotates and drives the rotating rod 401 to rotate, the rotating rod 401 rotates and drives the bracket 408 to rotate, the bracket 408 rotates and drives the nozzle 409 to rotate, so that the nozzle 409 can always face the steel structure. When the clamping plate 204 moves upward, the clamping plate 204 no longer blocks the photoelectric sensor 417, and the photoelectric sensor 417 opens the electric switching valve 412, so that the cold air pipe 413 is connected to the intake pipe 415, and the hot air pipe 414 is connected to the exhaust pipe 416, so that the low-temperature gas enters the nozzle 409 from the intake pipe 415, and then flows out from the nozzle 409 to clean the steel structure, and at the same time, the rivets on the steel structure can be cooled.
