[0027] Embodiment 2, on the basis of embodiment 1, the insurance detection member 7 comprises: an insurance detection arm 701, a limit plate 7011 and a swing plate 702, the insurance detection arm 701 is fixedly mounted on the welding connection plate 101 by bolts; the limit plate 7011 is fixedly mounted on the insurance detection arm 701; the limit plate 7011 is used to limit the stirrup connecting ribs; the swing plate 702 is rotatably mounted on the insurance detection arm 701; the swing plate 702 is used to fit on the stirrup connecting ribs; the top of the swing plate 702 is a slope structure; the inner side of the swing plate 702 is used to fit the stirrup The insurance detection member 7 also includes: a swing press switch 703, a reset tension spring 704 and a warning light 705. Two swing press switches 703 are fixedly installed on the insurance detection arm 701, and the two swing press switches 703 are respectively located on both sides of the insurance detection arm 701; two reset tension springs 704 are fixedly installed on the insurance detection arm 701, and the ends of the two reset tension springs 704 are respectively connected to the swing plate 702; two warning lights 705 are fixedly installed on the insurance detection arm 701; the two swing press switches 703 are respectively electrically By connecting two warning lights 705 and using the insurance detection piece 7, the welding accuracy of the stirrups can be further detected after the stirrup welding positioning is completed, which can avoid the problem that the stirrups with a large degree of elastic deformation affect the welding accuracy.

The swing plate 702 also plays the role of limiting the connecting reinforcement, and cooperates with the two reset tension springs 704 to ensure that the connecting reinforcement is attached to the box beam stirrups, ensuring the firmness of the connecting reinforcement and the stirrups during welding. When the push plate 302 pushes the connecting bar downward, the two limit plates 7011 can be used to limit the two ends of the connecting bar to ensure that the connecting bar is located between the two stirrups. As the connecting bar descends, the connecting bar can be squeezed and fitted to one side of the box girder stirrup by the two swing plates 702, which is convenient for subsequent welding. After the welding positioning is completed, if the stirrup undergoes elastic deformation after losing the traction limit, the stirrup will be tilted to one side and will squeeze one side of the swing plate 702, and then squeeze the swing press switch 703 on the corresponding side, so as to control the corresponding prompt light 705 to light up.

[0028] The working principle of this embodiment is as follows: first, a row of connecting bars are pre-stored inside the steel bar storage shell 201, and the pushing plate 205 is elastically pushed and clamped. By holding the handle provided on the welding connecting plate 101, the inner side of the welding connecting plate 101 is fitted to the box girder stirrups. At this time, the electric push rod 301 can be started to push the pushing plate 302 down, and the positioning magnet 303 is used to absorb the connecting bars in the steel bar storage shell 201 to ensure stable pushing. After the connecting bars are pushed to one side of the box girder stirrups, the welding connecting plate 101 is held and docked with the box girder stirrups. The correction clamping block 402 can slide into the bending part of the box girder stirrups using its own inclined structure. During the process, the tension spring 404 is elastically pulled and adapted to clamp the clamping plate 603 to fit the box girder. The hydraulic cylinder 602 is controlled to push the clamping plate 603 to fit the box girder tightly. The micro switch 604 is squeezed, and the two prestressed electromagnets 102 can be controlled to be energized and started. At this time, the prestressed electromagnet 102 can be controlled to magnetically attract the prestressed slider 401, driving the clamping groove 4021 on the inner side of the correction clamping block 402 to clamp the bending part of the stirrup and apply prestress. At this time, the correction electromagnet 502 can be turned on again to magnetically pull back the correction clamping block 402 to promote the box girder stirrup to fit the inner side of the welding connection plate 101, which also plays a correction role. At this time, with the heating of the electric heating plate 203, after the welding is completed, the middle heated connecting rib can adapt to the small elastic deformation of the stirrup, and the stress can be released by annealing, and the correction quality can be guaranteed; spot welding can be carried out by the welding gun 103, and then the pushing plate 302 can be controlled to rise and reset. After the pushing plate 302 does not block a row of connecting ribs inside the steel bar storage shell 201, the pushing plate 205 can be driven under the traction of the pushing spring 206 to push a row of connecting ribs to fill the position, and the next welding work can be carried out; When the pushing plate 302 pushes the connecting reinforcement downward, the connecting reinforcement can be squeezed and fitted to one side of the box beam stirrup by the two swing plates 702, which is convenient for subsequent welding. After the welding positioning is completed, the prestressed electromagnet 102 and the correction electromagnet 502 are powered off. At this time, the correction clamping block 402 no longer pulls the limiting stirrup. If the stirrup undergoes elastic deformation after losing the traction limit, the stirrup will tilt to one side and squeeze one side of the swing plate 702, and then squeeze the swing press switch 703 on the corresponding side, so as to control the corresponding prompt light 705 to light up as a prompt, so that the staff can understand that the current stirrup has an excessive deformation and needs further adjustment and correction.
