Description

Technical Field

[0001] The utility model relates to the technical field of steel structure welding, in particular to a welding device for building steel structures. Background Technique

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and anti-rust processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. The components or parts are usually connected by welds, bolts or rivets. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields. In steel structure components, welding occupies a large proportion of the work; when welding existing steel structures, a welding cap needs to be worn for protection, but the welding cap cannot be worn well by operators with different head circumferences. At the same time, insufficient pressure during welding will cause sparks to splash. If the workers are not protected safely, it will cause workers to be injured or damage their clothes;

[0003] After retrieval, in the prior art, the authorized publication number is: CN220145111U, which discloses a steel structure welding device, including a base and a welding assembly.

A threaded hole is formed in the convex block. A lead screw is connected to the threaded hole by threads. A fitting for assisting in clamping the steel structure is arranged on the bent rod. In the utility model, during the rotation of the lead screw, the bent rod can clamp and fix two steel structures on the base together, so that the ends of the two steel structures are closely attached, which is convenient for subsequent welding. After the bent rod fixes the two steel structures, any steel structure will not shift in position when subjected to an external force. Therefore, the welding quality is higher;

[0004] When the above patent is used, it cannot protect and block the staff, resulting in the splashing sparks during welding scalding the staff or damaging the clothes of the staff, thus having an adverse impact on the welding work; therefore, we need to propose a welding device for building steel structures.

[0022] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0023] The utility model provides: a welding device for building steel structures, as Figures 1-4As shown in the figure, it includes a workbench 1 and a protective cover 2. An installation frame 3 is fixedly arranged on the upper surface of the workbench 1. A storage board 8 is slidably arranged on the upper surface of the installation frame 3. Two groups of clamping plates 12 are slidably arranged on the upper surface of the storage board 8. Sliding grooves 11 corresponding to the installation frame 3 are opened on both sides of the protective cover 2. A welding groove is opened on the surface of the protective cover 2, and a number of protective brushes 6 are arranged inside the welding groove;

[0024] A driving component is arranged on the upper surface of the workbench 1 for driving the protective cover 2 to rotate to block the installation frame 3;

[0025] Opening the welding groove facilitates the staff to use a welding torch to weld the steel structure. The protective brush 6 is made of a flame-retardant material. While blocking the splashing sparks through the protective brush 6, it prevents the protective brush 6 from burning. Cooperating with the protective cover 2 to block the splashing sparks, it further avoids the splashing sparks during the welding process from causing injury to the staff or damaging the staff's clothing. And opening the sliding groove 11 ensures that the steel structure can still move inside the protective cover 2 when it is too long.

[0026] Preferably, the driving component includes a driving motor 4, a rotating shaft 13, a worm 14, a worm gear 15 and a connection module; the driving motor 4 is bolted to the upper surface of the workbench 1. The rotating shaft 13 is key-connected to the output end of the driving motor 4. The worm 14 is fixedly connected to one end of the rotating shaft 13. And the worm gear 15 is rotatably arranged above the worm 14. And the worm 14 is meshed with the worm gear 15. Starting the driving motor 4 drives the rotating shaft 13 to rotate. The rotating shaft 13 drives the worm 14 to rotate. Thus, the worm 14 drives the worm gear 15 to rotate through meshing.

[0027] It should be noted that the connection module includes a driving plate 5, a placement plate 9, a support plate 10, a connection column 16 and an auxiliary plate 17. There are two groups of support plates 10. The two groups of support plates 10 and the placement plate 9 are all fixedly installed on the upper surface of the workbench 1. One end of the worm 14 away from the driving motor 4 is rotatably connected to the placement plate 9. The connection column 16 is rotatably arranged between the two groups of support plates 10. And the worm gear 15 is fixedly sleeved on the outer arc surface of the connection column 16. The rotation of the worm gear 15 will drive the connection column 16 to rotate. And the two groups of support plates 10 support the worm gear 15 and the connection column 16. And the placement plate 9 supports the other end of the worm 14. Thus, the stability during the rotation of the worm 14 and the worm gear 15 is ensured.

[0028] Further, one ends of the driving plate 5 and the auxiliary plate 17 are respectively rotatably arranged on the back surfaces of the two groups of support plates 10, and the connecting column 16 rotatably penetrates through the two groups of support plates 10 and is fixedly connected to the driving plate 5 and the auxiliary plate 17. The other end of the auxiliary plate 17 is fixedly connected to the driving plate 5, and the other end of the driving plate 5 is fixedly connected to the protective cover 2. When the worm 14 drives the worm wheel 15 to rotate, the worm wheel 15 will drive the driving plate 5 and the auxiliary plate 17 to rotate through the connecting column 16, thereby driving the protective cover 2 to flip. The auxiliary plate 17 is arranged to assist in connecting the driving plate 5, thereby improving the stability of the protective cover 2 during the rotation process.

[0029] Furthermore, a lead screw 18 is rotatably arranged inside the mounting frame 3. A moving block 19 is threadedly sleeved on the outer arc surface of the lead screw 18 inside the mounting frame 3. One end of the mounting frame 3 is bolted with a servo motor 22, and the lead screw 18 is key-connected to the output end of the servo motor 22. Starting the servo motor 22 drives the lead screw 18 to rotate, and the lead screw 18 drives the moving block 19 to move along the lead screw 18 through the thread.

[0030] Specifically, a moving groove 21 corresponding to the moving block 19 is opened on the upper surface of the mounting frame 3. The placing plate 8 is fixedly installed on the upper surface of the moving block 19, and support side plates 20 are fixedly installed on both sides of the placing plate 8. The moving block 19 is arranged as a convex block, so as to ensure that the moving block 19 does not rotate along with the lead screw 18 during the moving process. When the moving block 19 moves, it drives the placing plate 8 to move, and further drives the steel structure on the upper surface of the placing plate 8 to move. When it is necessary to weld other surfaces of the steel structure, only need to open the protective cover 2 to flip the steel structure.

[0031] In addition, electric push rods 7 are fixedly installed on the corresponding surfaces of the two groups of support side plates 20, and two groups of clamping plates 12 are respectively fixedly installed on the corresponding surfaces of the two groups of electric push rods 7. The two groups of electric push rods 7 are supported by the support side plates 20, and the two groups of electric push rods 7 are used to push the clamping plates 12 to move on the upper surface of the placing plate 8, so as to clamp and fix the steel structure through the two groups of clamping plates 12.
