Description

Technical Field

[0001] The utility model relates to the technical field of steel box girder welding, in particular to a steel box girder welding auxiliary tool. Background Art

[0002] Steel box girder, also known as steel plate box girder, is a commonly used structural form for large-span bridges. It is generally used on bridges with larger spans. It is called a steel box girder because of its box-like appearance. Steel box girder is generally composed of top plate, bottom plate, web plate, transverse diaphragm, longitudinal diaphragm and stiffening ribs connected by full welding. The top plate is an orthogonal anisotropic bridge deck composed of a cover plate and longitudinal stiffening ribs.

[0003] For example, the patent document with the announcement number CN 217193533 U discloses a steel box girder welding auxiliary tool, including a base, an adjustment rod, an adjustment sleeve and two positioning rods. The base is provided with a transversely extended slide groove, the lower end of the positioning rod is slidably connected in the slide groove, and the positioning rod is bolted to the base; the top of the positioning rod is connected to a lifting plate, and a lifting hole is provided on the lifting plate; one end of the adjustment rod is slidably connected in the adjustment sleeve, the other end of the adjustment rod is bolted to one of the positioning rods, and the end of the adjustment sleeve away from the adjustment rod is bolted to the other positioning rod. The auxiliary tool of this scheme can be adjusted according to the size of the steel box girder, so that it can fit tightly around the steel box girder, which can effectively avoid the loosening between the steel box girder and the auxiliary tool during welding, improve stability, and reduce safety risks during operation.

[0004] However, in the actual use of this structure, the docking operation with the steel box girder welding position can often only be achieved by manually adjusting the welding equipment, which will lead to low overall welding efficiency of the equipment. At the same time, the equipment cannot perform rapid limit adjustment operations at the interface with the steel box girder, resulting in the inability to obtain stable limit operations during the actual welding of the steel box girder, and cannot meet daily welding needs. Therefore, it is urgent to design a steel box girder welding auxiliary tool to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a steel box girder welding auxiliary tool to solve the problem proposed in the above background technology that in the actual use of the existing structure, the welding equipment can often only be manually adjusted to achieve the docking operation with the steel box girder welding position, which will lead to low overall welding efficiency of the equipment. At the same time, the equipment cannot perform rapid limit adjustment operation at the interface with the steel box girder, resulting in the inability to obtain stable limit operation during the actual welding process of the steel box girder and the inability to meet daily welding needs.

[0006] To achieve the above object, the utility model provides the following technical solution: a steel box beam welding auxiliary tool, comprising a first inner positioning frame, an adjusting ring frame is arranged on the side of the first inner positioning frame, an outer positioning frame is arranged on the side of the adjusting ring frame, and an adjusting swivel seat is arranged on the top side of the adjusting ring frame;

[0007] An overhead rod, wherein the four corners of the back of the first inner positioning frame are fixedly connected with the overhead rod, and one end of the overhead rod away from the first inner positioning frame is fixedly connected with the second inner positioning frame, and the second inner positioning frame has the same structure as the first inner positioning frame.

[0008] Preferably, an electric push rod is provided inside the overhead rod, and one end of the electric push rod is fixedly connected to a movable seat.

[0009] Preferably, a first butt-jointed rubber pad is provided at one end of the overhead rod, and a second butt-jointed rubber pad is provided on the back side of the movable seat.

[0010] Preferably, a control seat is fixedly connected to the top of the adjusting swivel seat, and a welding equipment body is arranged at the bottom of the adjusting swivel seat.

[0011] Preferably, an adjustment groove is provided on the side surface of the adjustment annular frame, and a damping rubber ring is provided on the inner wall of the adjustment groove.

[0012] Preferably, the four corners of the inner walls of the first inner positioning frame and the outer positioning frame are fixedly connected to the limiting foot seats, and the surface center of the limiting foot seats is provided with a limiting rolling ball.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The steel box girder welding auxiliary tool can perform rapid positioning and welding operations on the equipment and the two ends of the steel box girder by means of the first inner positioning frame, the adjusting ring frame, the outer positioning frame, the adjusting swivel seat, the second inner positioning frame, the control seat, the welding equipment body, the adjusting groove and the damping rubber ring. In actual use, the staff will first dock the two ends of the steel box girder to be welded to the first inner positioning frame and the second inner positioning frame respectively. At this time, the two ends of the steel box girder can be initially positioned, so that the three groups of steel box girders can be initially positioned and docked. Then, the adjusting swivel seat at the top of the adjusting ring frame can be directly adjusted by circular rotation along the adjusting groove on the side of the adjusting ring frame, and the damping rubber ring on the inner wall of the adjusting groove can be stably limited. At this time, the two ends of the steel box girder can be quickly welded through the control seat and the welding equipment body, so that the welding on the two ends of the steel box girder can be stably limited, which reflects the practicality of the equipment design.

[0015] The steel box girder welding auxiliary tool further improves the overall use effect of the equipment by setting the first inner positioning frame, the outer positioning frame, the overhead rod, the second inner positioning frame, the electric push rod, the movable seat, the first docking rubber pad, the second docking rubber pad, the limit foot and the limit ball. In daily use, the staff can start the electric push rod inside the overhead rod at the four corners between the first inner positioning frame and the second inner positioning frame to drive the movable seat at one end to perform telescopic adjustment operations, so that the length between the first inner positioning frame and the second inner positioning frame can always adapt to the length of each steel box girder. At the same time, the limit feet and limit balls at the four corners of the inner walls of the first inner positioning frame and the outer positioning frame can be used to quickly perform docking operations on the steel box girder between the first inner positioning frame and the second inner positioning frame, thereby meeting daily welding needs and reflecting the comprehensiveness of the equipment design.
