For behaviors that seriously endanger the country and society, criminal law is even used. Steel structures are needed in engineering construction, and steel structures need to be welded when they are used. Therefore, a welding device for steel structure engineering construction is needed.

[0003] When operators perform welding work on steel structures for engineering construction, they often use corresponding welding devices for steel structure engineering construction. Although the existing devices can achieve the purpose of welding, in actual use, they often need to manually clamp the steel structure to maintain stability during welding. However, this operation method increases the labor intensity of the operators, which may reduce the welding efficiency of the steel structure. In addition, due to the different sizes of steel structures, multiple adjustments are required to clamp and fix steel structures of different sizes, which reduces the practicality.

[0020] See also Figure 1-4 The utility model provides a technical solution: a welding device for steel structure engineering construction, including a bottom plate 1, movable plates 2 are movably installed on both sides of the top of the bottom plate 1, the bottom of the movable plate 2 is movably connected to the top of the bottom plate 1, and the top of the movable plate 2 is hinged with a cover plate 3, and fixed plates 4 are fixedly installed on both sides of the top of the movable plate 2. A circular shaft 5 is rotatably installed between the fixed plates 4, and a rotating rod 6 is fixedly sleeved on both ends of the surface of the circular shaft 5. A moving rod 7 is hinged between the rotating rod 6 and the cover plate 3. When the circular shaft 5 rotates between the fixed plates 4, the rotating rod 6 will be driven to rotate, and then the moving rod 7 will be driven to rotate. A gear 8 is fixedly sleeved on the surface of the circular shaft 5, and a rack 9 located below the gear 8 is movably installed on the top of the movable plate 2, and the outer surface of the rack 9 is meshed with the outer surface of the gear 8. When the rack 9 slides, it will drive the gear 8 to rotate, and one end of the rack 9 is fixedly installed with a push plate 10. A pneumatic cylinder 11 is fixedly installed on the top, and the output end of the pneumatic cylinder 11 is fixedly connected to one end of the push plate 10. When the pneumatic cylinder 11 is in operation, the push plate 10 will slide, and a welder 12 is fixedly installed on the top of the base plate 1, and the welder 12 can weld the steel structure. Round rods 13 are movably installed on both sides of the top of the cover plate 3, and a round plate 16 is fixedly installed on the top of the round rod 13. The bottom of the round rod 13 penetrates the cover plate 3 and extends to the bottom of the cover plate 3. The outer surface of the round rod 13 and the interior of the cover plate 3 are smooth, so that the round rod 13 can slide more smoothly inside the cover plate 3 and reduce the occurrence of jams. A pressing plate 14 is fixedly installed on the bottom of the round rod 13, and a spring 15 is fixedly installed between the pressing plate 14 and the cover plate 3, and the inner surface of the spring 15 is movably connected to the outer surface of the round rod 13. When the bottom of the pressing plate 14 contacts the steel structure, the spring 15 will be squeezed to put it in a compressed state.

[0021] A fixed block 21 is fixedly installed on the top of the movable plate 2, and a fixed groove 22 is opened on the top of the fixed block 21. The fixed groove 22 can place the steel structure. Slide grooves 17 are opened on both sides of the top of the bottom plate 1. A screw rod 18 is rotatably installed inside the slide groove 17. A sleeve 19 is threadedly sleeved on the surface of the screw rod 18, and the top of the sleeve 19 is movably connected to the bottom of the movable plate 2. When the screw rod 18 rotates, it will drive the sleeve 19 to slide inside the slide groove 17, thereby driving the movable plate 2 to slide. A turning handle 20 is rotatably installed on both sides of the bottom plate 1, and one side of the turning handle 20 passes through the bottom plate 1 and is fixedly connected to one side of the screw rod 18. When the turning handle 20 rotates, it will drive the screw rod 18 to rotate. Brackets 23 are fixedly installed at the four corners of the bottom of the bottom plate 1.

[0022] Working principle: When welding work is required on the steel structure for engineering construction, the operator first places the steel structure inside the fixing groove 22, and then starts the pneumatic cylinder 11. The operation of the pneumatic cylinder 11 will cause the push plate 10 to slide, and then drive the rack 9 to slide. At this time, the rack 9 will drive the gear 8 to rotate, and then drive the circular shaft 5 to rotate between the two fixed plates 4, and at the same time drive the rotating rod 6 to rotate, and then drive the moving rod 7 to rotate, so that the position of the cover plate 3 can be adjusted. Secondly, when the cover plate 3 slides, it will drive the pressing plate 14 to rotate synchronously. Sliding occurs. When the bottom of the pressure plate 14 reaches the top of the steel structure, the pressure plate 14 will drive the round rod 13 to slide inside the cover plate 3. At the same time, the pressure plate 14 will also squeeze the spring 15 to make it in a compressed state, so that steel structures of different sizes can be clamped and fixed. Finally, the turning handle 20 is turned. The rotation of the turning handle 20 will rotate the screw rod 18, and then drive the sliding sleeve 19 to slide inside the sliding groove 17, which can drive the movable plate 2 and the rigid mechanism on its top to slide, so that the two steel structures are connected, and then they are welded using the welder 12.
