Description

Technical Field

[0001] This utility model belongs to the technical field of steel structure welding equipment, and specifically relates to a steel structure installation welding device. Background Technology

[0002] Steel structures refer to structural members such as steel beams, steel columns, and steel trusses made of steel sections and steel plates. The members or components are usually connected by welds, bolts, or rivets. On the construction site, it is usually necessary to manually install and weld multiple steel pipes and steel columns into steel supports. Workers generally use welding machines to perform welding on site. When welding steel pipes at the construction site, the steel parts to be welded are manually aligned and then welded manually using a handheld welding machine. During the welding process, the steel parts are not installed and positioned, which is not conducive to the welding operation and is prone to deviation of the welded steel pipe workpiece. There are shortcomings that need to be improved. When welding steel pipes at existing construction sites, there is a problem with the design of installation and welding brackets to fix the steel pipe workpieces. To address this, this application proposes a steel structure installation and welding device. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1 to 6 This utility model provides a technical solution: a steel structure installation and welding device, including a frame mechanism, including a base plate 11 and a fixing plate 12 fixed by welding, and a support arm 13 fixed by welding to the fixing plate 12. The support arm 13 is perpendicular to the fixing plate 12 and supports the mounting plate 2, allowing the mounting plate 2 to be placed flat on the support arm 13. It also includes a separate mounting plate 2 combined with the support arm 13, with the mounting plate 2 placed horizontally on the support arm 13. The mounting plate 2 and the support arm 13 are separate components, allowing the mounting plate 2 to be manually removed and placed on the support arm 13 at different heights. This is suitable for welding steel workpieces at different heights. A positioning plate 3 is connected to the surface of the mounting plate 2, which serves to limit the workpiece. A strong permanent magnet 31 is glued to the surface of the positioning plate 3 facing the mounting plate 2. 1. The mounting plate 2, supported by a magnetic metal material, is fixed by magnetic adsorption. The position between the opposing positioning plates 3 can be manually changed, which is suitable for limiting the position of steel workpieces and preventing displacement of the steel workpieces during welding. It also includes a clamping assembly for fixing the steel workpiece, including a mounting base 4, a guide rod 51 passing through the mounting base 4, a compression spring 53 sleeved on the outside of the guide rod 51, a clamping plate 52 connected to one end of the guide rod 51 by a thread, and a lifting assembly. The clamping assembly is used to clamp the steel workpiece and prevent the steel workpiece from becoming unstable and displacing during welding. When the steel workpiece is placed in the mounting base 4, the clamping plate 52 and the guide rod 51 are moved manually along their own axial direction. The clamping plate 52 compresses the compression spring 53, and one end of the steel workpiece is manually placed between the mounting base 4 and the clamping plate 52. When the clamping plate 52 is released, the clamping plate 52 clamps the steel workpiece under the elastic force of the compression spring 53.

[0017] In this embodiment, the lifting assembly includes a stabilizing plate 61 of the vertical clamping plate 52, a lifting rod 62 passing through the stabilizing plate 61, and an anti-slip plate 63 fixedly connected to the bottom end of the lifting rod 62. The inner surface of the mounting base 4 is provided with limiting teeth 41, and the bottom surface of the anti-slip plate 63 is provided with a tooth groove that cooperates with the limiting teeth 41. The anti-slip plate 63 is engaged with the limiting teeth 41 to prevent the anti-slip plate 63 and the mounting base 4 from sliding. The lifting rod 62 is manually lifted to make the anti-slip plate 63 leave the limiting teeth 41. There is a gap between the anti-slip plate 63 and the mounting base 4 to facilitate the movement of the clamping plate 52.

[0018] In this embodiment, both ends of the mounting base 4 are right-angle structures, and a horizontal plate is provided at the bottom of the clamping plate 52. The center of the horizontal plate is provided with a square groove for the anti-slip plate 63 to pass through, thereby limiting the anti-slip plate 63.

[0019] In this embodiment, the positioning plate 3 has a right-angle structure. The strong permanent magnet 31 is connected to the mounting plate 2 by magnetic adsorption. The positioning plate 3 and the mounting plate 2 are stably attached, which has the function of limiting the workpiece placed on the mounting plate 2. The positioning plate 3 has a vertical lifting column, which makes it easy to move the positioning plate 3.

[0020] In this embodiment, a limiting block 21 inserted into the support arm 13 is fixed on the bottom surface of the mounting plate 2. When the mounting plate 2 is installed on the support arm 13, the limiting block 21 engages with the support arm 13, ensuring accurate installation of the mounting plate 2. Symmetrically distributed diagonal bracing plates 22 are fixed on the bottom surface of the mounting plate 2 by welding. A right-angled connecting plate 23 is welded to one end of the diagonal bracing plate 22 away from the mounting plate 2. The inner surface of the connecting plate 23 matches the outer surface of the long strip-shaped support arm 13. While the mounting plate 2 is installed on the support arm 13, the support arm 13 supports the connecting plate 23. The connecting plate 23, the support arm 13, and the mounting plate 2 form a triangular frame structure, ensuring stable connection between the mounting plate 2 and the support arm 13.

[0021] In this embodiment, a split lower baffle 14 is connected to the surface of the base plate 11. A 141 insert block is welded to the bottom surface of the lower baffle 14 and inserted into the base plate 11. An upper baffle 15 is fixed to the fixing plate 12 by screws. A vertically connected partition 151 is provided on the upper baffle 15. The lower baffle 14 is combined with the base plate 11 and the position of the lower baffle 14 on the base plate 11 can be manually adjusted. The lower baffle 14 and the base plate 11 are further fixed by hand-tightening screws. The steel workpiece can be placed at an angle, with the bottom end of the steel workpiece placed on the surface of the base plate 11. The lower baffle 14 blocks the bottom end of the steel workpiece, and the upper baffle 15 supports the tilted steel workpiece.

[0022] Working principle and usage process of this utility model: Mounting plate 2 is placed horizontally on support arm 13. Mounting plate 2 and support arm 13 are separate assembly structures. Mounting plate 2 can be manually picked up and put in, which makes it easy to place mounting plate 2 on support arm 13 at different heights. It is suitable for welding steel workpieces at different heights. The bottom end of the steel workpiece is placed on the surface of the base plate 11. The lower baffle 14 blocks the bottom end of the steel workpiece, and the upper baffle 15 supports the inclined steel workpiece. While the mounting plate 2 is installed on the support arm 13, the support arm 13 supports the connecting plate 23. The connecting plate 23, the support arm 13, and the mounting plate 2 form a triangular frame structure, which makes the connection between the mounting plate 2 and the support arm 13 stable. When placing a steel workpiece in the mounting seat 4 of the mounting plate 2, manually lift the lifting rod 62 to make the anti-slip plate 63 leave the limiting teeth 41. There is a gap between the anti-slip plate 63 and the mounting seat 4, which facilitates the movement of the clamping plate 52. Manually move the clamping plate 52, and the guide rod 51 moves along its own axis. The clamping plate 52 squeezes the compression spring 53. Manually place one end of the steel workpiece between the mounting base 4 and the clamping plate 52. Release the clamping plate 52, and under the elastic force of the compression spring 53, the clamping plate 52 clamps the steel workpiece. The lifting rod 62 is lowered, and the anti-slip plate 63 engages with the limiting tooth 41 to prevent the anti-slip plate 63 and the mounting base 4 from sliding. The position of the positioning plate 3 is changed so that the opposing positioning plate 3 restricts the steel workpiece. The strong permanent magnet 31 is connected to the mounting plate 2 by magnetic adsorption. The positioning plate 3 and the mounting plate 2 are in stable contact, which has the function of restricting the workpiece placed on the mounting plate 2 and preventing the steel workpiece from tilting. In summary, this application provides an auxiliary welding bracket device for fixing steel pipe workpieces during on-site welding. The mounting base 4 and clamping plate 52 clamp the steel workpiece, and the positioning plate 3 limits the workpiece placed on the mounting plate 2, thus preventing the steel workpiece from tilting during the welding process.
