[0033] See also Figure 1 as well as Figure 2 The present embodiment provides a welding device for steel structures of construction projects, including a base plate 10, a first driving assembly 20, a welding assembly 30, an annular piston block 40 and a second driving assembly 50. Two groups of bracket plates 101 are fixedly arranged on the upper part of the base plate 10. The two groups of bracket plates 101 are relatively distributed. Positioning sleeves 102 are penetrated and fixedly arranged on the two groups of bracket plates 101. The welding assembly 30 is arranged at the edge between the two groups of positioning sleeves 102. The first driving assembly 20 is arranged outside one group of positioning sleeves 102, and is used to drive the welding assembly 30 to rotate. Another group of the positioning sleeves 102 is provided with an air collecting cavity in its wall, and another group of the positioning sleeves 102 is provided with a plurality of air inlet holes 103 in communication with the air collecting cavity at one end. The annular piston block 40 is movably arranged inside the air collecting cavity, and the second driving assembly 50 is installed outside the other group of the positioning sleeves 102. When the welding assembly 30 rotates, the second driving assembly 50 is used to drive the annular piston block 40 to slide along the inside of the air collecting cavity so as to draw the smoke generated during welding from the plurality of air inlet holes 103 into the inside of the air collecting cavity.

[0034] When it is necessary to weld two groups of steel pipes into one, the two groups of steel pipes can be passed through the two groups of positioning sleeves 102 respectively, while ensuring that one end of the two groups of steel pipes extends between the two groups of positioning sleeves 102. At this time, the welding assembly 30 is facing the welding gap between the two groups of steel pipes. Then the first driving assembly 20 drives the welding assembly 30 to rotate around the steel pipe, and the two groups of steel pipes are welded into one during the rotation of the welding assembly 30; during the rotation of the above-mentioned welding assembly 30, the second driving assembly 50 drives the annular piston block 40 to slide along the inside of the gas collecting cavity, and then the smoke generated during the welding process is extracted from the multiple air inlet holes 103 into the inside of the gas collecting cavity, thereby preventing the smoke from diffusing and preventing the smoke from being inhaled into the body by the staff, thereby endangering human health.

[0035] See also Figure 1 In one embodiment, the first driving assembly 20 includes a driving gear 201, a driving motor 202, a ring gear 203, a rotating drum 204 and a support plate 205. The driving motor 202 is fixedly mounted on the upper portion of the base plate 10. The driving gear 201 is arranged at the output end of the driving motor 202. The rotating drum 204 is rotatably arranged outside one group of the positioning sleeves 102. The ring gear 203 is fixedly arranged on the outer wall of the rotating drum 204 and meshes with the driving gear 201. One end of the support plate 205 is fixedly connected to the rotating drum 204, and the other end is connected to the welding assembly 30.

[0036] After the two groups of steel pipes pass through the two groups of positioning sleeves 102 respectively and a welding gap is formed between the two groups of positioning sleeves 102, the driving motor 202 drives the driving gear 201 to rotate, and through the meshing action between the driving gear 201 and the gear ring 203, the rotating drum 204 is driven to rotate compared with the corresponding positioning sleeve 102. When the rotating drum 204 rotates, it drives the support plate 205 and the welding assembly 30 to rotate. The welding assembly 30 rotates around the two groups of steel pipes, thereby realizing comprehensive welding between the two groups of steel pipes.

[0037] See also Figure 1 , Figure 3 as well as Figure 4In one embodiment, a slide groove 106 is provided on the side wall of another group of the positioning sleeves 102 along the length direction, and the second driving assembly 50 includes a sleeve 501, a push rod 502 and a spiral protrusion 504. The sleeve 501 is slidably sleeved on the outside of the other group of the positioning sleeves 102, and a connecting rod 505 is fixedly arranged on the inner wall of the sleeve 501. The end of the connecting rod 505 away from the sleeve 501 extends from the slide groove 106 to the inside of the positioning sleeve 102 and is connected to the annular piston block 40. The end of the support plate 205 away from the rotating cylinder 204 extends to the outside of the other group of the positioning sleeves 102. The spiral protrusion 504 is fixedly arranged on the outer wall of the other group of the positioning sleeves 102. One end of the push rod 502 is fixedly connected to the support plate 205, and the other end extends to one side of the spiral protrusion 504.

[0038] When the support plate 205 drives the welding assembly 30 to rotate around the two groups of steel pipes to weld the two groups of steel pipes into one, the support plate 205 can also drive the push rod 502 to rotate. When the push rod 502 rotates, it acts on one side of the spiral protrusion 504, and then applies an axial thrust to the sleeve 501, thereby pushing the sleeve 501 to slide along the outside of another group of positioning sleeves 102. When the sleeve 501 slides, it drives the annular piston block 40 to slide along the inside of the gas collecting cavity through the connecting rod 505, thereby extracting the smoke generated during the welding process from the multiple air inlet holes 103 into the inside of the gas collecting cavity, thereby collecting the welding smoke and preventing the welding smoke from being inhaled by the human body.

[0039] See also Figure 1 In one embodiment, an exhaust pipe 104 is provided on the outer wall of another group of the positioning sleeves 102, and a one-way valve (not shown in the figure) is provided inside the exhaust pipe 104 and inside several of the air inlet holes 103. A purification layer 105 is also provided inside the exhaust pipe 104. One end of the sliding sleeve 501 is connected to the bracket plate 101 through an elastic member 503, and the elastic member 503 is used to provide elastic support for the sliding sleeve 501.

[0040] When the sleeve 501 slides along the outside of the positioning sleeve 102 and drives the annular piston block 40 to slide along the inside of the gas collecting cavity, the elastic member 503 is compressed by force. When the welding assembly 30 rotates around the two groups of steel pipes for one circle, the welding of the two groups of steel pipes is completed. At this time, the push rod 502 synchronously rotates around the positioning sleeve 102 for one circle, and the push rod 502 slides off from one end of the spiral protrusion 504. The sleeve 501 is no longer subjected to the thrust of the push rod 501. The elastic member 503 can push the sleeve 501 to make the sleeve 501 slide in the opposite direction along the outside of the positioning sleeve 102. When the sleeve 501 slides in the opposite direction, the annular piston block 40 is driven to slide in the opposite direction along the inside of the gas collecting cavity through the connecting rod 505, and then the smoke inside the gas collecting cavity is pressed out through the exhaust pipe 104, completing the exhaust of the smoke. When the smoke is discharged along the inside of the exhaust pipe 104, the purification layer 105 can purify the harmful particles in the smoke.

[0041] In one embodiment, the elastic member 503 may be a spring or a metal spring, which is not limited here.

[0042] In one embodiment, the purification layer 105 may be an activated carbon layer purification layer or a filter layer, which is not limited here.

[0043] In one embodiment, the welding assembly 30 is a laser welding gun.

[0044] In an embodiment of the present invention, when it is necessary to weld two groups of steel pipes into one, the two groups of steel pipes can be respectively passed through the inside of the two groups of positioning sleeves 102, while ensuring that one end of the two groups of steel pipes extends between the two groups of positioning sleeves 102. At this time, the welding assembly 30 is facing the welding gap between the two groups of steel pipes, and then the first driving assembly 20 drives the welding assembly 30 to rotate around the steel pipe, and the two groups of steel pipes are welded into one during the rotation of the welding assembly 30; during the rotation of the above-mentioned welding assembly 30, the second driving assembly 50 drives the annular piston block 40 to slide along the inside of the gas collecting cavity, and then the smoke generated during the welding process is extracted from the several air inlet holes 103 into the inside of the gas collecting cavity, thereby preventing the smoke from diffusing and preventing the smoke from being inhaled into the body of the staff and endangering human health. Compared with the prior art, during the welding process of the two groups of steel pipes, the welding smoke can be effectively collected, thereby preventing the welding smoke from being inhaled into the body of the staff and threatening human health, thereby improving the safety and protection of the welding process.
