[0002] Steel structures are structures made of steel materials and are 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.

However, in actual use, the steel structure may have uneven areas, and it is impossible to grind the steel structure before welding, which reduces the welding quality. Furthermore, it is impossible to grind the steel structure after welding, which reduces the working efficiency of the welding equipment.

[0024] Example 3: An auxiliary mechanism 5 is provided above the base plate 1; The auxiliary mechanism 5 includes a storage box 501, an exhaust fan 502, an air suction pipe 503, a fixed plate 504, a filter screen 505, and a connecting plate 506. The inner wall of the storage box 501 is connected to one end of the exhaust fan 502, and one end of the exhaust fan 502 is connected to one end of the air suction pipe 503.

One end of the fixing plate 504 is fixedly connected to one side of the mounting plate 306, so that the fumes generated during welding can be collected quickly and conveniently and filtered and discharged. Furthermore, the storage box 501 has an air outlet on one side, and there are two connecting plates 506. The connecting plates 506 are symmetrically distributed at the bottom of the moving plate 403. The bottom of the scraper 507 is pressed against the top of the base plate 1, so that when the moving plate 403 moves, the scraper 507 can be moved, thereby cleaning the welding and grinding debris on the base plate 1 and collecting and storing the debris in the collection box 508.

[0025] The implementation principle of a steel structure welding device for engineering construction in this embodiment is as follows: When welding work is required on the steel structure, the operator places the steel structure into two placement plates 408, moves the two steel structures relative to each other, and aligns them. At this time, the motor 302 is started, which drives the gear 303 to rotate. The rotation of the gear 303 drives the gear 323 to rotate, which drives the rotating rod 321 to rotate. The rotation of the rotating rod 321 drives the grinding roller 322 to rotate, and the rotation of the grinding roller 322 can perform grinding work on the steel structure. When the grinding is completed, the motor 302 is stopped. At this time, by activating the electric telescopic rod 305, the mounting plate 306 is moved. The movement of the mounting plate 306 causes the telescopic rod 307 to extend and retract, thereby increasing the stability of the mounting plate 306 during movement. The movement of the mounting plate 306 indirectly drives the gear 310 and welding torch 312 to move downwards. As the gear 310 moves, it meshes with the gear 303. At this time, by activating the motor 302, the gear 303 is rotated. The rotation of the gear 303 drives the gear 310 to rotate. The rotation of the gear 310 drives the rotating plate 311 to rotate. The rotation of plate 311 drives the welding torch 312 to rotate, enabling welding of the steel structure. As plate 311 rotates, it drives the fan blades 313 to rotate, dispersing the welding fumes. Before the welding torch 312 operates, the movement of rack 308 drives gear 314 to rotate, which in turn drives worm 315, which in turn drives worm wheel 316, which in turn drives threaded rod 317, which in turn drives threaded sleeve 318. The movement of 318 causes the connecting plate 319 to slide within the limiting plate 320. The sliding of the connecting plate 319 indirectly drives the grinding roller 322 to move, thereby moving the grinding roller 322 downward away from the steel structure, thus enabling welding work on the steel structure. After welding is completed, the upward movement of the rack 308 causes the gear 314 to reverse, allowing the grinding roller 322 to move upward. It also enables the gear 4 323 to mesh with the gear 1 303, thereby causing the grinding roller 322 to rotate and grind the welded steel structure. This effectively improves the working efficiency of the welding device and allows for better welding work. When welding is required on the steel structure, the operator places the steel structure into the placement plate 408. By rotating the threaded rod 409, the clamping plate 410 is moved, thus clamping and fixing the steel structure. After clamping and fixing, the electric telescopic rod 402 is activated, causing the moving plate 403 to slide on the guide rod 404. The sliding of the moving plate 403 causes the fixing rod 405 to move, which in turn indirectly moves the placement plate 408. This allows the steel structure to be moved and connected. At this time, the welding torch 312 can be used to weld the steel structure. During welding, the motor 407 is activated, causing the placement plate 408 to rotate. The rotation of the placement plate 408 causes the steel structure to rotate. Since the welding torch 312 has a telescopic function, the steel structure will not damage the welding torch 312 when it rotates. Therefore, welding can be performed without the operator constantly adjusting the position and angle of the steel structure, thereby improving the working efficiency of the welding device and making it more convenient for the operator to use. When welding is required on the steel structure, the operator clamps and fixes the steel structure using the clamping mechanism 4, and moves and connects the steel structure relative to each other. The welding mechanism 3 then welds and grinds the steel structure. During welding, the exhaust fan 502 is activated to draw the welding fumes into the storage box 501 through the suction pipe 503. The exhaust fan 502, in conjunction with the rotating fan blades 313, can better collect the fumes. Once the fumes enter the storage box 501, they pass through the filter screen 505 installed inside the storage box 501 to remove impurities. The system filters out impurities and stores them in storage box 501. The filtered flue gas is discharged through an air outlet on one side of storage box 501. The sliding of movable plate 403 moves connecting plate 3 506, which in turn moves scraper 507. The scraper 507 cleans the welding and grinding debris on the base plate 1, pushing the debris into collection box 508 for collection and storage. This makes the system more convenient for operators and reduces their workload.
