Description

Technical Field

[0001] This utility model relates to the field of bridge technology, and in particular to a welding deformation correction device for steel structure bridges. Background Technology

[0002] Steel structure bridges are widely used in the construction of various large, medium and small bridges, such as railway bridges, highway bridges and cross-sea bridges, due to their advantages such as light weight, high strength and short construction period. However, in the construction of steel structure bridges, welding is an important process to connect various steel structure components, but uneven heat input will be generated during the welding process, which will cause deformation of the welded parts, thus requiring welding deformation correction devices.

[0003] Most deformation correction devices on the market have overly simple structures, and their height adjustment components have a relatively complex adjustment process, which makes it impossible to perform simple and effective deformation correction on steel structures of different heights.

[0004] Therefore, a welding deformation correction device for steel structure bridges is needed. Utility Model Content

[0005] This utility model proposes a welding deformation correction device for steel structure bridges, which solves the problem that most existing deformation correction devices on the market have overly simple structures and their height adjustment components have relatively complex adjustment processes, resulting in the inability to perform simple and effective deformation correction for steel structures of different heights.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

A first threaded post is provided at the rotating end of the first motor. A connecting post is fixed at the other end of the first threaded post. A first threaded plate is threadedly connected to the periphery of the first threaded post. A first slider is fixed to the side wall of the first threaded plate.

[0014] This utility model proposes a welding deformation correction device for steel structure bridges. Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The steel structure bridge welding deformation correction device is equipped with a first threaded column and a first threaded plate. By turning on the first motor, the first threaded column can be rotated. The rotation of the first threaded column can move the first threaded plate, which in turn can move the moving plate. The relative or back-to-back movement of the two sets of moving plates can extend and retract the scissor frame. The extension and retraction of the scissor frame can raise and lower the lifting plate. During the raising and lowering of the lifting plate, the welding deformation correction component can be raised and lowered, adjusting the height of the welding deformation correction component. This avoids the situation where most of the deformation correction device is too simple in structure and lacks a height adjustment component, which would prevent the deformation correction of steel structures of different heights.

[0016] 2. The steel structure bridge welding deformation correction device is equipped with a second threaded column and a second threaded plate. By turning on the second motor, the second threaded column can be rotated. The rotation of the second threaded column can move the second threaded plate. The movement of the second threaded plate can move the movable plate. The movement of the movable plate can move the support frame. The relative movement of the two sets of support frames can form a clamping assembly, so that the heating pipe and the extrusion plate clamp the welded part of the column steel structure. The heating pipe preheats the area and then the extrusion plate extrudes and corrects it. Attached Figure Description

[0025] Furthermore, a second motor 23 is fixed inside the hollow plate 17. A second threaded post 24 is provided at the rotating end of the second motor 23. A second threaded plate 25 is threadedly connected to the outer periphery of the second threaded post 24. A movable plate 27 is provided on one side of the second threaded plate 25. A first rotating shaft 26 is provided at the connection between the second threaded plate 25 and the movable plate 27. A second rotating shaft 28 is provided at the connection between the movable plate 27 and the support frame 18. A second slider 29 is fixed to the bottom side wall of the support frame 18. A second slide rail 30 is provided on the outer side of the second slider 29.

[0026] Furthermore, the connecting column 4 and the first threaded column 3 form a rotating structure through the operation of the first motor 2, and the first threaded column 3 and the first threaded plate 5 form a threaded connection. The first threaded plate 5 forms a sliding structure through the first slider 6 and the first slide rail 7, and the first threaded plate 5 and the moving plate 8 form a fixed structure. When the first motor 2 is turned on, the first threaded column 3 can be driven to rotate. Through the threaded connection between the first threaded column 3 and the first threaded plate 5, the rotation of the first threaded column 3 can move the first threaded plate 5, and the first threaded plate 5 can move the moving plate 8.

[0027] Furthermore, the movable plate 8 forms a sliding structure with the fixed slide rail 10 via the cylindrical slider 9, and the cylindrical slider 9 forms a rotating structure with the scissor frame 12 via the first bearing 11. The scissor frame 12 forms a lifting structure with the supporting slide column 14 via the second bearing 13, and the supporting slide column 14 forms a sliding structure with the lifting plate 16 via the supporting slide rail 15. The relative or back-to-back movement of the two sets of movable plates 8 can extend and retract the scissor frame 12.

During the raising and lowering process of the lifting plate 16, the welding deformation correction component can be raised and lowered to adjust the height of the welding deformation correction component.

[0028] Furthermore, the second threaded post 24 forms a rotating structure through the operation of the second motor 23, and the second threaded post 24 is threadedly connected to the second threaded plate 25. The second threaded plate 25 forms a rotating structure with the movable plate 27 through the first rotating shaft 26, and the movable plate 27 forms a rotating structure with the support frame 18 through the second rotating shaft 28. When the second motor 23 is turned on, the second threaded post 24 can be driven to rotate. Through the threaded connection between the second threaded post 24 and the second threaded plate 25, the rotation of the second threaded post 24 can move the second threaded plate 25. The movement of the second threaded plate 25 can move the movable plate 27. The movement of the movable plate 27 can move the support frame 18.

[0029] Furthermore, the support frame 18 forms a sliding structure with the second slide rail 30 via the second slider 29, and the support frame 18 forms a fixed structure with the extrusion plate 19. The support frame 18 also forms an elastic structure with the heating tube 22 via the damper 20 and the spring 21. The relative movement of the two sets of support frames 18 can form a clamping assembly, so that the heating tube 22 and the extrusion plate 19 each clamp the welded part of the column steel structure. The heating tube 22 is used for preheating, and then the extrusion plate 19 is used for extrusion and correction.

[0030] Working principle: First, the operator needs to turn on the first motor 2, which drives the first threaded column 3 to rotate. The rotation of the first threaded column 3 causes the first threaded plate 5 to move, which in turn causes the moving plate 8 to move. The relative or back-to-back movement of the two sets of moving plates 8 causes the scissor frame 12 to extend and retract. The extension and retraction of the scissor frame 12 causes the lifting plate 16 to rise and fall. During the rising and falling of the lifting plate 16, the welding deformation correction component can be raised and lowered to adjust its height. Then, by turning on the second motor 23, the operator can drive the second threaded column 24 to rotate. The rotation of the second threaded column 24 causes the second threaded plate 25 to move. The movement of the second threaded plate 25 causes the moving plate 27 to move. The movement of the moving plate 27 causes the support frame 18 to move. The relative movement of the two sets of support frames 18 can form a clamping component, so that the heating tube 22 and the extrusion plate 19 each clamp the welding point of the column steel structure. The heating tube 22 preheats the steel structure, and then the extrusion plate 19 performs extrusion correction.
