[0001] This utility model relates to the field of steel structure technology, and more specifically, it relates to a liftable support for steel structure welding. Background Technology
[0002] Steel structure is a structural form that uses steel as the main building material and is widely used in various engineering fields such as construction, bridges, towers, and warehouses. It is mainly composed of structural steel (such as H-beams, I-beams, angle steel, etc.) and steel plates, which are combined into various structural components, such as steel beams, steel columns, and steel trusses, through welding, bolting, or riveting to form a complete structural system. In steel structure engineering, welding operations often need to be carried out at different heights and positions. However, the existing adjustable supports for steel structure welding are inconvenient to adjust and do not make it easy to securely fix the steel structure. Utility Model Content
[0003] (1) Technical problems to be solved In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a liftable support for steel structure welding, which has the characteristics of convenient adjustment and easy and secure fixation of steel structure.
[0004] (2) Technical solution To achieve the above objectives, this utility model provides a liftable support for steel structure welding, including a base plate. A fixed shell is fixedly connected to the top of the base plate. A first bearing is provided on each of the opposite inner walls of the fixed shell. The same first rotating shaft passes through the interior of the two first bearings, and a winding wheel is fixedly connected to the surface of the first rotating shaft. A motor is fixedly connected to the side of the fixed shell via a fixed frame. A steel wire rope is wound and fixedly fixed to the surface of the winding wheel. A second rotating shaft is movably connected to the opposite inner wall of the fixed shell. A guide wheel is fixedly connected to the surface of the second rotating shaft. A lifting plate is movably connected inside the fixed shell. A through hole is opened at the top of the lifting plate. The steel wire rope passes through the through hole and overlaps with the surface of the guide wheel, so that one end of the steel wire rope is fixedly connected to the lifting plate. A movable shell is fixedly connected to the top of the lifting plate. A U-shaped support plate is fixedly connected to the top of the movable shell. A threaded hole is opened on the surface of the U-shaped support plate. A threaded post is threadedly connected inside the threaded hole. A rotating plate is fixedly connected to one end of the threaded post. A second bearing is sleeved on the other end of the threaded post, and a limit plate is fixedly connected to the end face of the second bearing.
[0005] When using the liftable support frame for steel structure welding according to this technical solution, by... Furthermore, limit blocks are fixedly connected to both sides of the lifting plate, and limit grooves are formed on the opposite inner walls of the fixed shell, with the limit blocks slidably connected inside the limit grooves.
[0006] Furthermore, rectangular through holes are provided on the opposite inner walls of the movable shell, and the second rotating shaft is movably connected inside the two rectangular through holes.
[0007] Furthermore, a limiting hole is formed on the surface of the U-shaped support plate, and a limiting rod is fixedly connected to the surface of the limiting plate, with the limiting rod slidably connected inside the limiting hole.
[0008] Furthermore, the surface of the limiting plate is provided with a rubber pad, and a brake wheel is fixedly connected to the bottom of the base plate.
[0009] (3) Beneficial effects In summary, this utility model has the following beneficial effects: 1. This liftable support for steel structure welding is equipped with a motor, a winding wheel, and a wire rope. The motor drives the winding wheel to rotate, winding or releasing the wire rope. Under the guidance of the guide wheel, the lifting plate is raised and lowered, realizing convenient adjustment of the welding height of the steel structure. At the same time, the limiting blocks on both sides of the lifting plate slide in the limiting grooves on the inner wall of the fixed shell, effectively limiting the movement trajectory of the lifting plate and avoiding deviation or shaking during the lifting process. This ensures the stability and accuracy of the lifting adjustment and solves the problem of inconvenient adjustment of traditional supports. 2. The lifting support for steel structure welding is equipped with a rotating plate, threaded column, and limiting plate. The U-shaped support plate provides stable support for the steel structure. When the operator rotates the rotating plate, the threaded column rotates in the threaded hole. The threaded column pushes the limiting plate closer to the steel structure until the rubber pad is tightly attached to the surface of the steel structure. The limiting rod slides in the limiting hole to limit the limiting plate and prevent the limiting plate from rotating with the threaded column, ensuring that the limiting plate always clamps the steel structure smoothly.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.
[0014] Example: The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.
[0015] Please see Figure 1-3This utility model provides a technical solution: a liftable support for steel structure welding, including a base plate 1, a fixed shell 2 fixedly connected to the top of the base plate 1, a first bearing provided on each of the opposite inner walls of the fixed shell 2, a first rotating shaft passing through the interior of the two first bearings, and a winding wheel 3 fixedly connected to the surface of the first rotating shaft, a motor 5 fixedly connected to the side of the fixed shell 2 via a fixed frame 4, a steel wire rope 6 wound and fixedly fixed to the surface of the winding wheel 3, a second rotating shaft 11 movably connected to the opposite inner wall of the fixed shell 2, a guide wheel 12 fixedly connected to the surface of the second rotating shaft 11, a lifting plate 7 movably connected inside the fixed shell 2, a through hole opened at the top of the lifting plate 7, the steel wire rope 6 passing through the through hole and overlapping with the surface of the guide wheel 12, so that one end of the steel wire rope 6 is fixedly connected to the lifting plate 7, a movable shell 8 fixedly connected to the top of the lifting plate 7, and a U-shaped support fixedly connected to the top of the movable shell 8. The support plate 13 has threaded holes 14 on its surface. A threaded post 15 is threaded into the inside of the threaded hole 14. One end of the threaded post 15 is fixedly connected to a rotating plate 16, and the other end of the threaded post 15 is fitted with a second bearing. A limit plate 18 is fixedly connected to the end face of the second bearing. A motor 5, a winding wheel 3, and a wire rope 6 are provided. The motor 5 drives the winding wheel 3 to rotate, winding or releasing the wire rope 6. Under the guidance of the guide wheel 12, the lifting plate 7 is raised or lowered, enabling convenient adjustment of the welding height of the steel structure. Simultaneously, the limit blocks 10 on both sides of the lifting plate 7 slide within the limit grooves 9 on the inner wall of the fixed shell 2, effectively limiting the movement trajectory of the lifting plate 7 and preventing deviation or shaking during lifting. This ensures the stability and accuracy of the lifting adjustment, solving the problem of inconvenient adjustment of traditional supports. By setting the rotating plate 16, threaded post 15, and limit plate 18, the U-shaped support plate 13 achieves a high-quality lifting height adjustment. The support plate provides stable support for the steel structure. The operator rotates the rotating plate 16, which drives the threaded column 15 to rotate in the threaded hole 14. The threaded column 15 pushes the limiting plate 18 closer to the steel structure until the rubber pad 19 is tightly attached to the surface of the steel structure. The limiting rod 17 slides in the limiting hole to limit the limiting plate 18, preventing the limiting plate 18 from rotating with the threaded column 15 and ensuring that the limiting plate 18 always clamps the steel structure smoothly.
[0016] Specifically, limit blocks 10 are fixedly connected to both sides of the lifting plate 7, and limit grooves 9 are opened on the opposite inner walls of the fixed shell 2, with the limit blocks 10 slidably connected inside the limit grooves 9.
[0017] By adopting the above technical solution, the limiting block 10 slides inside the limiting groove 9, which plays a limiting role on the lifting plate 7, making the lifting plate 7 more stable when it moves.
[0018] Specifically, rectangular through holes 22 are provided on the inner walls of the movable shell 8, and the second rotating shaft 11 is movably connected inside the two rectangular through holes 22.
[0019] Specifically, a limiting hole is provided on the surface of the U-shaped support plate 13, and a limiting rod 17 is fixedly connected to the surface of the limiting plate 18. The limiting rod 17 is slidably connected inside the limiting hole.
[0020] By adopting the above technical solution, the limiting rod 17 slides inside the limiting hole, thereby limiting the limiting plate 18.
[0021] Specifically, the surface of the limiting plate 18 is provided with a rubber pad 19, and the bottom of the base plate 1 is fixedly connected with a brake wheel 20.
[0022] By adopting the above technical solution, the friction between the rubber pad 19 and the steel structure is increased.
[0023] It should be noted that the diameter of the wire rope can be changed and adjusted according to the actual working conditions on site, and the wire rope diameter ranges from 2mm to 30mm.
[0024] The working principle of this utility model is as follows: In use, the bracket is first pushed, and the brake wheel 20 at the bottom of the base plate 1 is used to move it to the designated position for the steel structure welding operation. After confirming the position, the brake wheel 20 is locked, and the steel structure to be welded is placed stably on the U-shaped support plate to ensure that the steel structure is placed accurately and corresponds to the position required for the welding operation. The operator rotates the rotating plate 16, which drives the threaded column 15 to rotate in the threaded hole 14. The threaded column 15 pushes the limiting plate 18 to move towards the steel structure. At this time, the limiting rod 17 slides synchronously in the limiting hole, which limits the limiting plate 18. The rotating plate 16 is rotated continuously until the rubber pad 19 on the surface of the limiting plate 18 is tightly attached to the surface of the steel structure, thus achieving a firm fixation of the steel structure. The motor 5 is started by the control switch, which drives the first rotating shaft to rotate, thereby causing the winding wheel 3 to rotate. When the winding wheel 3 winds up the wire rope 6, the wire rope... 6. Under the guidance of the guide wheel 12, the lifting plate 7 is pulled up. When the winding wheel 3 releases the wire rope 6, the lifting plate 7 descends under its own weight. During the lifting process, the limit blocks 10 on both sides of the lifting plate 7 slide in the limit groove 9 to ensure smooth lifting. According to the height required for the welding operation, the motor 5 is controlled to rotate forward and backward. After the lifting plate 7 is adjusted to a suitable height, the motor 5 is turned off. After confirming that the steel structure is firmly fixed and the height of the lifting plate 7 is appropriate, the operator can carry out the welding operation of the steel structure. After the welding operation is completed, the rotating plate 16 is rotated in the opposite direction to make the limit plate 18 move away from the steel structure and release the fixation of the steel structure. The welded steel structure is removed from the U-shaped support plate. Then, the lifting plate 7 is lowered to the initial position by the motor 5. The motor 5 is turned off. Finally, the locking of the brake wheel 20 is released and the bracket is moved to the storage position.
[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
