A screw rod 8 connected by thread penetration is provided at the axis of the moving disk 10, and the outer wall of the moving disk 10 is rotatably embedded in the inner wall of the transmission ring 11.

The transmission ring 11 pushes the loading frame 13 to move synchronously through the compressed return spring 12.

[0037] The bump at the bottom of the transmission ring 11 is slidably fitted in the chute opened on the loading rack 13. A transmission tooth plate 22 and a rotating gear 23 are fitted against the inner wall of the lower part of the loading rack 13. The upper surface of the end of the transmission tooth plate 22 is fixedly connected to the bump at the bottom of the transmission ring 11. A rotating gear 23 is meshed below the transmission tooth plate 22. A shaft rod 24 is fixedly penetrated through the axis of the rotating gear 23. Both ends of the shaft rod 24 are rotatably penetrated through the loading rack 13. The end of the shaft rod 24 is fixedly penetrated and installed at the top of the swing arm 2501. When the loading rack 13 is blocked by the blocking rack 2 and cannot move, the transmission ring 11 can continue to move within the loading rack 13. The transmission ring 11 will drive the rotating gear 23 to rotate through the transmission tooth plate 22, and the rotating gear 23 will drive the swing arm 2501 to rotate through the shaft rod 24. Since a through groove 2502 is opened at the lower end of the swing arm 2501, and a connecting shaft at the top of the inner plate 2503 is fitted against the through groove 2502. An inclined groove 2504 is opened through the side wall of the lower part of the inner plate 2503. Guide grooves 2507 in an inverted "L" shape structure are opened on both sides of the outer guide sleeve frame 2506. The bottom of the outer guide sleeve frame 2506 is slidably inserted into the top of the mounting frame 2508. A stress rod 2505 is fixedly connected to the inner wall of the top of the mounting frame 2508. The stress rod 2505 respectively passes through the top of the inclined groove 2504 and the bottom of the guide groove 2507. The mounting frames 2508 are symmetrically distributed on both sides of the limiting box 16. At this time, the swing arm 2501 will drive the inner plate 2503 to move upward. At this time, the inclined groove 2504 on the inner plate 2503 will drive the stress rod 2505 to move along the guide groove 2507 on the outer guide sleeve frame 2506. The stress rod 2505 will drive the mounting frame 2508 and the welding torch head 26 to move synchronously. Since cross bars 30 symmetrically distributed are fixedly connected to both sides of the upper part of the loading rack 13, and the cross bars 30 penetrate through the top of the storage cylinder 28 to form a sliding limit structure. A docking rod 27 is slidably inserted into the bottom of the storage cylinder 28. A stress spring 29 is fixedly connected between the upper end surface of the docking rod 27 and the top inner wall of the storage cylinder 28. The lower end surface of the docking rod 27 is fixedly connected to the outer wall of the top of the mounting frame 2508. A welding torch head 26 is fixedly connected to the bottom surface of the mounting frame 2508, and the welding torch head 26 is inclined. At this time, the mounting frame 2508 will drive the docking rod 27 to move upward and then horizontally.

[0038] The guiding and positioning module further includes a pressure frame 18 fittingly arranged between the connecting plates 15. The pressure frame 18 is in a "T" - shaped structure. The lower part of the pressure frame 18 passes through the opening at the top of the limiting box 16. The lower end of the pressure frame 18 is fixedly connected to the top of the pressure plate 17. At both ends of the upper part of the pressure frame 18, corresponding vertical rods 19 are slidably penetrated. A pressure spring 20 is sleeved on the outer side of the rod body of the vertical rod 19, and the pressure spring 20 is fixedly connected between the top of the vertical rod 19 and the outer wall of the end of the pressure frame 18. The upper end face of the vertical rod 19 is fixedly connected to the moving end of the electric cylinder 21, and the electric cylinder 21 is fixedly penetrated and installed on the top of the base 1. A convex ring is arranged at the bottom end of the vertical rod 19, so that the electric cylinder 21 can drive the pressure frame 18 to move downward through the vertical rod 19 and the pressure spring 20. Since the guiding and positioning module includes a connecting plate 15 fixedly installed in the middle of the guiding column 7, a screw rod 8 is rotatably penetrated through the top of the connecting plate 15. The lower end of the connecting plate 15 is fixedly connected with a horizontal limiting box 16. The top of the inner wall of the limiting box 16 is fittingly provided with a horizontal pressure plate 17, and the bottom surface of the pressure plate 17 is higher than the port of the feeding sleeve 3. The port of the feeding sleeve 3 faces the port of the limiting box 16. At this time, the pressure frame 18 will drive the pressure plate 17 to move downward along the inner wall of the limiting box 16.

[0039] Working principle: When using this auxiliary welding device for bridge formwork, first refer to Figures 1 - 12 , the user pushes the reinforcing bar to be welded into the limiting box 16 through the feeding sleeve 3. Then the device controls the electric cylinder 21 to start. The electric cylinder 21 will apply pressure to the pressure frame 18 through the pressure spring 20 on the vertical rod 19. At this time, the pressure frame 18 will drive the pressure plate 17 to move downward. At this time, the pressure plate 17 will press the reinforcing bar in the limiting box 16 tightly against the formwork.

[0040] Then the device controls the driving motor 9 to start. The driving motor 9 will drive the two moving disks 10 to move synchronously along the guiding column 7 through the screw rod 8. The two moving disks 10 will move away from each other. The moving disks 10 will push the loading rack 13 to move synchronously through the transmission ring 11 and the return spring 12. The limiting sleeve 14 on the loading rack 13 will move along the guiding column 7. At this time, the outer guiding sleeve frame 2506 at the bottom of the loading rack 13 will drive the welding torch head 26 to move synchronously through the mounting rack 2508. The user can freely adjust the welding torch head 26 for intermittent spot welding or continuous welding. The welding torch head 26 starts to weld and fix the side of the reinforcing bar on the outer wall of the formwork.

[0041] When the welding torch head 26 finishes welding the side of the reinforcing rib, the welding torch head 26 will automatically enter the secondary movement state to weld the end of the reinforcing rib on the flange of the template. During this process, the loading rack 13 will first fit against the side wall of the stop rack 2 and cannot move. At this time, the welding torch head 26 will align with the fitting point at the end of the reinforcing rib. When the screw rod 8 continues to rotate, the moving disk 10 will continue to drive the transmission ring 11 to move within the loading rack 13, and the transmission ring 11 will further compress the reset spring 12 in the compressed state. At this time, the transmission ring 11 can drive the transmission tooth plate 22 to move at the bottom of the loading rack 13. The transmission tooth plate 22 will drive the rotating gear 23 to rotate, and the rotating gear 23 will drive the swing arm 2501 to rotate downward through the shaft rod 24. At this time, the swing arm 2501 will drive the inner plate 2503 to move upward through the through groove 2502. The inclined groove 2504 on the inner plate 2503 will exert pressure on the force-bearing rod 2505, enabling the force-bearing rod 2505 to move along the guiding groove 2507 on the outer guiding sleeve frame 2506. Since the guiding groove 2507 is in an inverted "L" shape structure, at this time, the force-bearing rod 2505 will drive the welding torch head 26 to move synchronously through the mounting frame 2508, so that the welding torch head 26 can move along the joint between the end of the reinforcing rib and the template flange, thereby completing the welding of the end of the reinforcing rib. During this process, the mounting frame 2508 will first drive the docking rod 27 to move upward, the docking rod 27 will compress the force-bearing spring 29, and then the docking rod 27 will drive the receiving cylinder 28 to move horizontally along the cross bar 30. When welding the next reinforcing rib, the loading will control the electric cylinder 21 to start. The electric cylinder 21 will drive the limiting box 16 to move upward through the transmission structure, so that the limiting box 16 is far away from the reinforcing rib. At the same time, the driving motor 9 drives the screw rod 8 to rotate in the reverse direction, and the loading rack 13 will move away from the stop rack 2 for reset operation. From the above steps, it can be seen that the welding torch head 26 will perform a reset operation synchronously. Then, the servo motor 5 controls the rotating frame 6 to rotate a set angle to facilitate the welding operation of one reinforcing rib.
