Description

[0002] In actual high pier bridge construction work, the wet joint method is usually adopted for construction. The wet joint connects the precast prestressed concrete beam blocks into a whole by cast-in-place concrete to ensure the structural integrity and stability of the long-span continuous beam. Before the wet joint, it is necessary to butt the stirrups of the box girder. Connecting bars are required to butt the stirrups. Usually, a batch of bundled steel wires are positioned or spot-welded and then welded together. At present, the stirrup welding work for high pier construction mostly uses manual operation with a welding torch. It is not convenient to automatically discharge the connecting bars for positioning welding, the welding efficiency is low, the risk of manually holding the connecting bars is relatively high, and it is not convenient to automatically correct the stirrups. The welding accuracy of the stirrups is not good, it is not convenient to perform prestress annealing welding, the connecting bars are prone to deformation, and the internal stress of the connecting bars will affect the quality of the steel bar connection. It is also not convenient to automatically detect the position accuracy of the connecting bars. Manual observation is inconvenient and it is easy to cause omissions. Summary of the Invention

The steel bar storage shell 201 is fixedly installed on the side of the welding connection plate 101 through bolts; a guiding and clamping plate 202 is fixedly installed at the bottom of the steel bar storage shell 201, and the bottom of the guiding and clamping plate 202 is of an inclined surface structure; an electric heating plate 203 is fixedly embedded on the guiding and clamping plate 202, and the electric heating plate 203 is used for heating the stirrup connecting bars; two propulsion control shafts 204 are slidably installed on the steel bar storage shell 201, and propulsion plates 205 are fixedly installed at the ends of the two propulsion control shafts 204; pushing springs 206 are respectively sleeved on the two propulsion control shafts 204, and the ends of the two pushing springs 206 are respectively fixedly installed on the side of the steel bar storage shell 201, and the other ends of the two pushing springs 206 are respectively fixedly installed at the ends of the propulsion control shafts 204; the connecting bar pushing member 3 includes: an electric push rod 301, a pushing plate 302, and a positioning magnet 303.

This structure adopts the steel bar storage part 2, which can realize the storage of connecting bars, can perform spot welding positioning work in batches, and can improve the welding positioning efficiency. This structure can use the connecting bar pushing member 3 to continuously push the connecting bars for welding work. At the same time, the welding connection plate 101 adopted by this structure can be held by hand, with stronger flexibility, and can directly hold this structure to butt the box girder stirrups, and the welding is accurate and fast. This structure is specifically optimized for the welding of box girder stirrups to ensure the construction efficiency of the wet joint. The connecting bars in the steel bar storage shell 201 are adsorbed by the positioning magnet 303 to ensure stable pushing. After the connecting bars are pushed to one side of the box girder stirrups, they can be spot welded by the welding torch 103. Then, the pushing plate 302 can be controlled to rise and reset. After the pushing plate 302 does not block a row of connecting bars inside the steel bar storage shell 201, under the traction of the pushing spring 206, the propulsion plate 205 can be driven to push a row of connecting bars to make up the position.

[0041] In the embodiments of the present disclosure, the stirrup prestressing member 4 includes: a prestressed slider 401, a correction clamping block 402, a clamping groove 4021, a limiting slider 403, and a matching tension spring 404. The prestressed slider 401 is slidably installed in the sliding groove 1011; a correction clamping block 402 is fixedly installed on the prestressed slider 401, and the upper and lower sides of the correction clamping block 402 are respectively bevel structures; the prestressed electromagnet 102 is used to magnetically attract the prestressed slider 401; a clamping groove 4021 is formed on the side of the correction clamping block 402, and the clamping groove 4021 is used to clamp the stirrup; a limiting slider 403 is fixedly installed on the side of the correction clamping block 402, and the limiting slider 403 is slidably inserted on the prestressed slider 401; a matching tension spring 404 is sleeved on the correction clamping block 402, and the end of the matching tension spring 404 is fixedly installed on the prestressed slider 401; the other end of the matching tension spring 404 is fixedly installed on the correction clamping block 402; the magnetic attraction correction member 5 includes: a magnetic attraction connection frame 501 and a correction electromagnet 502. The magnetic attraction connection frame 501 is fixedly installed on the welding connection plate 101; two correction electromagnets 502 are fixedly installed on the magnetic attraction connection frame 501, and the two correction electromagnets 502 are respectively used to magnetically attract the two correction clamping blocks 402. By using the stirrup prestressing member 4, it is possible to cooperate with the magnetic attraction correction member 5 to facilitate the direct sliding insertion of the stirrup into the box girder. The bending structure of the box girder stirrup can be utilized, and the stirrup prestressing member 4 can be used to achieve inward tightening, assisting in the prestress pulling work of the box girder stirrup, realizing the application of prestress. At the same time, by using the magnetic attraction pulling force of the magnetic attraction correction member 5, it is possible to assist in correcting the offset stirrup, improving the welding accuracy of this structure, ensuring the tension of the connecting bar after welding. At the same time, this structure cooperates with the electric heating plate 203. When the connecting bar is welded, stress relief annealing of the connecting bar can be carried out, avoiding the problem of weld detachment due to internal stress existing after the connecting bar is welded. At the same time, the connecting bar can be softened by heating, further ensuring that both sides of the connecting bar can fit the box girder stirrup, ensuring the spot welding positioning accuracy, and avoiding the problem of gaps between the connecting bar and the box girder stirrup due to a certain misalignment between two adjacent box girder stirrups. Control the prestressed electromagnet 102 to magnetically attract the prestressed slider 401, drive the clamping groove 4021 inside the correction clamping block 402 to clamp the bent part of the stirrup, and apply prestress. At this time, the correction electromagnet 502 can be turned on again to magnetically attract and pull back the correction clamping block 402, promoting the box girder stirrup to fit inside the welding connection plate 101, and also playing a role in correction. At this time, with the heating of the electric heating plate 203, after welding is completed, the centrally heated connecting bar can adapt to the small elastic deformation of the stirrup, and by using the annealing method, the stress is released, and the correction quality can be guaranteed, ensuring that stress relief annealing is carried out in a timely manner after prestress deviation pulling.

[0042] In the embodiments of the present disclosure, the box girder positioning member 6 includes: a positioning seat 601 and a hydraulic cylinder 602. The positioning seat 601 is fixedly installed on the welding connecting plate 101; two hydraulic cylinders 602 are fixedly installed on the positioning seat 601; the positioning seat 601 is fixedly installed on the top of the magnetic attraction connecting frame 501; the box girder positioning member 6 further includes: clamping plates 603 and microswitches 604. Clamping plates 603 are respectively fixedly installed on the output shafts of the two hydraulic cylinders 602, and the clamping plates 603 are used for clamping and fitting the edges of the box girder; microswitches 604 are respectively fixedly installed on the output shafts of the two hydraulic cylinders 602, and the two microswitches 604 respectively pass through the clamping plates 603; the two microswitches 604 are respectively used for pressing and fitting the edges of the box girder; the two microswitches 604 are electrically connected to the two prestressed electromagnets 102. The use of the box girder positioning member 6 can facilitate the positioning of the positioning plate of this structure on the box girder, ensure the stability during correction, and at the same time, by using the method of positioning the box girder positioning member 6 on the box girder, under the limiting action of the clamping plates 603, it also ensures that the stirrups of the box girder can be perpendicular to the box girder, ensuring the correction accuracy. The microswitches 604 used can realize that after ensuring that the clamping plates 603 are limited and fitted to the box girder, the prestress application is controlled. The operation is simple and automatically controlled, ensuring that the connecting bars are also perpendicular to the box girder during welding.

[0043] Embodiment 2, on the basis of Embodiment 1, the insurance detection member 7 includes: an insurance detection arm 701, a limit plate 7011 and a swing plate 702. The insurance detection arm 701 is fixedly installed on the welding connection plate 101 by bolts; a limit plate 7011 is fixedly installed on the insurance detection arm 701; the limit plate 7011 is used to limit the stirrup connecting bars; a swing plate 702 is rotatably installed on the insurance detection arm 701; the swing plate 702 is used to fit on the stirrup connecting bars; the top of the swing plate 702 is a bevel structure; the inner side of the swing plate 702 is used to fit the stirrup connecting bars; the insurance detection member 7 further includes: a swing push switch 703, a return spring 704 and a warning lamp 705. Two swing push switches 703 are fixedly installed on the insurance detection arm 701, and the two swing push switches 703 are respectively located on both sides of the insurance detection arm 701; two return springs 704 are fixedly installed on the insurance detection arm 701, and the end parts of the two return springs 704 are respectively connected to the swing plate 702; two warning lamps 705 are fixedly installed on the insurance detection arm 701; the two swing push switches 703 are respectively electrically connected to the two warning lamps 705. By using the insurance detection member 7, it can be realized that after the stirrup welding positioning is completed, the welding accuracy of the stirrups can be further detected, and the problem that stirrups with a large degree of elastic deformation affect the welding accuracy can be avoided. The detection of this structure is flexible, which can ensure that the stirrups after welding positioning meet the standards, avoid missing inspections, and facilitate targeted rectification by the staff in the follow-up. The swing plate 702 also plays a role in limiting the connecting bars. With the pulling of the two return springs 704, it is ensured that the connecting bars are attached to the box girder stirrups, and the firmness of the connecting bars and stirrups during welding is guaranteed. When the pushing plate 302 pushes the connecting bars downward, the two limit plates 7011 can limit the two ends of the connecting bars to ensure that the connecting bars are located between the two stirrups. As the connecting bars descend, the connecting bars can be squeezed by the two swing plates 702 and fit on one side of the box girder stirrups, which is convenient for subsequent welding. After the welding positioning is completed, if the stirrups undergo elastic deformation after losing traction and limit, when the stirrups skew to one side, they will squeeze one side of the swing plate 702, and then squeeze the corresponding swing push switch 703 on that side, realizing the control of the corresponding warning lamp 705 to light up for warning.

[0044] Working principle of this embodiment: First, a row of connecting bars is pre-stored inside the steel bar storage shell 201. The pushing plate 205 elastically pushes and clamps them. By holding the handle provided on the welding connection plate 101, the inner side of the welding connection plate 101 is attached to the box girder stirrup. At this time, the electric push rod 301 can be started to push the pushing plate 302 downward. The positioning magnet 303 is used to adsorb the connecting bars inside the steel bar storage shell 201 to ensure stable pushing. After the connecting bars are pushed to one side of the box girder stirrup, when the welding connection plate 101 is held by hand and docked with the box girder stirrup, the correction clamping block 402 can slide into the bending part of the box girder stirrup by using its own inclined plane structure. During the process, the matching tension spring 404 elastically pulls and matches, and the clamping plate 603 is clamped and attached to the box girder. The hydraulic cylinder 602 is controlled to push the clamping plate 603 to closely fit the box girder, and the micro switch 604 is squeezed, so that 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 inside 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 attract and pull back the correction clamping block 402, promoting the box girder stirrup to fit inside the welding connection plate 101, and also playing a role in correction. At this time, with the heating of the electric heating plate 203, after welding is completed, the connecting bars heated in the middle can adapt to the small elastic deformation of the stirrup, and stress can be released by annealing, and the correction quality can also be guaranteed. Then, spot welding can be carried out by the welding torch 103. Subsequently, the pushing plate 302 can be controlled to rise and reset. After the pushing plate 302 does not block a row of connecting bars inside the steel bar storage shell 201, under the traction of the pushing spring 206, the pushing plate 205 can be driven to push a row of connecting bars to make up the position, and the next welding work can be carried out.

[0045] When the pushing plate 302 pushes the connecting bars downward, the connecting bars can be squeezed by the two swing plates 702 and attached to one side of the box girder stirrup, 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 and limits the stirrup. If the stirrup undergoes elastic deformation after losing the traction limit and skews to one side, it will squeeze one side of the swing plate 702, and then squeeze the corresponding swing pressing switch 703 on that side, so as to control the corresponding indicator light 705 to light up for prompting, which is convenient for the staff to know that the current stirrup has excessive deformation and needs further adjustment and correction.
