[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields. Steel structure needs to be welded during the production process, and welding brackets are needed to fix it during the welding process.

[0003] Publication number: CN220698648U, discloses: a steel structure welding bracket. When welding the steel structure, the worker places the steel structure on a workbench and holds the handle to rotate it. The rotation of the threaded rod will drive the two movable frames to move and approach each other. The steel structure placed between the movable frames is clamped and fixed using the compression plates on the two movable frames, thereby improving the stability of the steel structure during the welding process.

[0004] The above-mentioned prior art still has the following shortcomings in the specific implementation process:

[0005] During the welding process of steel structures, it is generally necessary to weld all around the steel structure. When the steel structure is placed on a workbench for welding, the steel structure cannot be turned over. The welders need to constantly move and adjust their own position to weld the steel structure, or the staff need to remove the steel structure, adjust the angle and then re-fix it before welding, which increases the labor intensity of the staff and has low welding efficiency. At the same time, when the sizes of the steel structures to be welded on both sides are different, the docking position of the steel structures on both sides cannot be adjusted, and the docking point is easily misaligned, affecting the welding quality.

[0006] In response to the above problems, we propose a bracket for steel structure welding. Utility Model Content

DETAILED DESCRIPTION

[0028] This specific embodiment is a steel structure welding bracket, such as Figures 1-9 As shown, the bracket for welding steel structures includes a welding table 1, which has two arc-shaped grooves 5 relatively formed on the welding table 1, a gear ring 2 movably provided in the arc-shaped groove 5, a number of electric push rods 3 installed on the inner side of the gear ring 2, and a splint 4 connected to the telescopic end of the electric push rod 3. A rack 6 is engaged with the lower side of the gear ring 2, a screw rod 7 is provided on the lower side of the welding table 1, a movable plate 8 is threadedly provided on the screw rod 7, and a fixed rod 9 is fixed between the movable plate 8 and the racks 6 on both sides. An annular groove 14 with a T-shaped cross-section is provided on both sides of the gear ring 2, and a number of limit assemblies are provided on the welding table 1, which cooperate with the annular groove 14. Extension plates 12 are fixed at both ends of the welding table 1, a screw rod 13 is threadedly provided on the extension plate 12, and the upper end of the screw rod 13 is rotatably connected to a support plate 10, and a number of support rollers 11 are rotatably provided on the top of the support plate 10.

[0029] The support plate 10 and the support roller 11 facilitate supporting the steel structure to be welded. Combined with the rotation setting of the support roller 11, the steel structure is pushed toward the gear ring 2. At the same time, under the threaded cooperation of the screw 13 and the extension plate 12, combined with the rotation connection of the screw 13 and the support plate 10, it is convenient to adjust the up and down movement of the support plate 10, thereby driving the steel structure placed on the top to move up and down, facilitating the docking of steel structures of different sizes on both sides;

[0030] Among them, under the action of the electric push rod 3, combined with the clamping plate 4, it is convenient to clamp and fix the surrounding side of the steel structure to be welded from different directions, ensuring the stability of the steel structure during welding. At the same time, with the threaded cooperation between the screw rod 7 and the movable plate 8, it is convenient to adjust the movable plate 8 to move along the direction of the screw rod 7. Combined with the fixed rod 9, it drives the racks 6 on both sides to move synchronously. Under the meshing action of the rack 6 and the gear ring 2, it drives the gear rings 2 on both sides to rotate synchronously, and then drives the clamped and fixed steel structures on both sides to rotate synchronously, which is convenient for welding one circle of the joint of the two steel structures. There is no need for staff to manually flip the steel structure, which saves manpower and effectively improves the welding efficiency of the steel structure.

[0031] The limiting assembly includes an arc block 15, a fixed plate 16, a connecting rod 17 and a fixed block 18. Several fixed blocks 18 are relatively fixed on the welding table 1. The arc block 15 is movably matched with the annular groove 14, and the arc block 15 is rotatably provided with several balls on the inner side, which cooperate with the inner wall of the annular groove 14. The fixed plate 16 is fixed on the side of the arc block 15 away from the balls. The connecting rod 17 is fixedly connected between the fixing plate 16 and the fixed block 18. Through the movable cooperation of the arc block 15 and the annular groove 14, combined with the balls, the gear ring 2 is effectively supported and limited and guided, thereby ensuring the stability of the gear ring 2 during the rotation process. At the same time, with the mutual cooperation of the fixed block 18, the connecting rod 17 and the fixed plate 16, the stability of the arc block 15 is guaranteed.

[0032] A servo motor 23 is installed on the surface of one of the vertical plates 19, and the output end of the servo motor 23 is connected to the end portion of the screw rod 7. Two vertical plates 19 are relatively fixed at the bottom of the welding table 1, and the screw rod 7 is arranged between the two vertical plates 19. A guide rod 20 is provided on the upper side of the screw rod 7. The guide rod 20 passes through the movable plate 8, and the movable plate 8 and the guide rod 20 are slidably matched, which effectively plays a role of limiting and guiding the movable plate 8, thereby ensuring the stability of the movable plate 8 during the movement process.

[0033] Two T-shaped guide grooves 21 are relatively provided at the bottom of the welding table 1. A guide block 22 is slidingly arranged inside the guide groove 21. The outer end of the guide block 22 is fixedly connected to the adjacent rack 6. Through the sliding cooperation between the guide block 22 and the guide groove 21, the rack 6 is effectively supported and limited and guided, thereby ensuring the stability of the rack 6 during the movement process.

[0034] There are several circular holes relatively passing through the welding table 1, and a limit rod 24 is movably set inside the circular hole. The upper end of the limit rod 24 is fixedly connected to the bottom of the support plate 10. The limit rod 24 effectively limits and guides the support plate 10, ensuring the stability of the up and down movement of the support plate 10. A handle is connected to the bottom end of the screw 13 to facilitate the adjustment of the screw 13 for rotation.

[0035] Example:

[0036] When in use, first place the two steel structures to be welded on the support rollers 11 on the top of the support plates 10 on both sides, and under the rotation of the support rollers 11, push the steel structures toward the center until the two steel structures pass through the gear rings 2 on both sides and are butted together;

[0037] When the sizes of the two steel structures to be welded are different, the screw rod 13 is driven to rotate by turning the handle. Under the threaded cooperation of the screw rod 13 and the extension plate 12, combined with the rotational connection of the screw rod 13 and the support plate 10, and the movable cooperation of the limit rod 24 and the circular hole, the support plate 10 is driven to move up and down stably, thereby driving the steel structure placed on the support roller 11 on the top of the support plate 10 to move up and down synchronously, achieving the purpose of fine-tuning the height of the steel structure until the steel structures on both sides can be properly butted together, thereby ensuring the welding quality of the butt joint of the two steel structures, solving the problem in the prior art that when the steel structures to be welded on both sides have different sizes, the butt joint position of the steel structures on both sides cannot be adjusted, which easily leads to misalignment of the butt joint point and affects the welding quality.

[0038] After the two steel structures are adjusted to be connected, the electric push rod 3 is started. The electric push rod 3 is extended to drive the corresponding clamping plate 4 to approach the steel structure, and the surrounding side of the steel structure is clamped and fixed to ensure the stability of the steel structure during the welding process. After the two steel structures are clamped and fixed, the staff welds the joints of the two steel structures;

[0039] After the welding of the upper side of the two steel structures is completed, the servo motor 23 is started, and the screw rod 7 is driven to rotate by the servo motor 23. Under the threaded cooperation of the movable plate 8 and the screw rod 7, combined with the sliding cooperation of the movable plate 8 and the guide rod 20, the movable plate 8 is driven to move backward stably. Under the action of the fixed rod 9, the racks 6 on both sides are driven to move synchronously. Under the meshing action of the rack 6 and the gear ring 2, and the mutual cooperation of the arc block 15 and the annular groove 14, combined with the ball bearings on the arc block 15, the gear rings 2 on both sides are driven to rotate synchronously, thereby driving the steel structures clamped and fixed on both sides to flip synchronously, making it convenient for the staff to weld a week at the steel structure joint. This solves the problem that in the process of welding steel structures in the prior art, it is generally necessary to weld a week of the steel structure. When the steel structure is placed on a workbench for welding, the steel structure cannot be flipped, and the welders need to constantly move and adjust their own position to weld the steel structure, or the staff removes the steel structure, adjusts the angle and then re-fixes it for welding, which increases the labor intensity of the staff and has the disadvantage of low welding efficiency.

[0040] It should be further explained that the installation structure, connection method or setting method of each component in the present invention are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects. At the same time, the servo motor 23 and the electric push rod 3 in the present invention are all purchased on the market, and technical personnel in this field can install and use them according to requirements.

[0041] All technical features in this embodiment can be freely combined according to actual needs.
