Description

Technical Field

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

[0002] Steel structures are engineering structures made of steel materials such as sections and plates, primarily used in buildings, bridges, ships, and other fields. They are characterized by their light weight, ease of construction, and high strength and stability. Components or parts within steel structures are often connected by welding, a method that allows for more flexible and diverse structural forms. Welded connections not only offer high strength and excellent sealing properties, but also ensure that the steel structure effectively transmits and distributes loads when subjected to external forces, thereby maintaining structural stability and safety.

[0003] The existing Chinese patent with announcement number CN217942314U discloses a welding device for processing steel structures, including: a base, a support frame fixedly connected to the base, a lifting device provided on the support frame, a slide provided on the lifting device, a first slide groove provided inside the slide, a first driving device fixedly installed on the slide, a first lead screw fixedly connected to the output end of the first driving device, a slider threadedly connected to the first lead screw, a limiting column for limiting the slider fixedly connected to the first slide groove, a welding gun provided at the lower end of the slider, and a clamping mechanism provided on the base.

[0004] Although the above scheme is convenient for clamping steel structures and performing horizontal welding of steel structures during use, harmful gases will be generated during steel structure welding. The device lacks the ability to handle the harmful gases, which makes it easy for them to escape into the working environment and endanger the health of the operators. At the same time, the device does not meet the existing needs. Therefore, we propose a welding device for steel structure processing. Utility Model Content

[0026] It also includes a purification box 4, which is arranged on one side of the upper end of the lifting platform 2. Four equally spaced activated carbon air purification plates 23 are arranged inside the purification box 4. Two smoking hoods 7 are provided on the front and rear sides of the lower end of the lifting platform 2;

[0027] It also includes a transmission chamber 10, which is opened at the upper end of the base 1. Double-threaded transmission rods 11 are rotatably provided on both sides of the transmission chamber 10. The front and rear sides of the outside of the double-threaded transmission rod 11 are threadedly connected to a movable seat 13. One end of the movable seat 13 extends to the outside of the transmission chamber 10, and the end of the movable seat 13 located outside the transmission chamber 10 is slidably matched with the base 1.

[0028] During use, the starting motor 18 drives the first rotating shaft 14, which is meshed and transmitted by the bevel gear 17, and synchronously drives the second rotating shaft 15 and the third rotating shaft 16 to rotate, and then drives the double-threaded transmission rod 11, so that the two movable seats 13 move toward each other along the guide rod 12, adjust and dock the steel structure, rotate the knob 22 after the steel structure is docked, and fix the steel structure through the single-threaded rod 20 to lower the pressure plate 21 to ensure stable welding. The electric telescopic rod 3 controls the lifting platform 2 to move downward, and the electric slide rail 8 guides the welding mechanism 9 to operate precisely. During welding, the suction machine 5 sucks away harmful smoke through the connecting pipe 6 and the smoke hood 7 and enters the purification box 4. The built-in activated carbon air purification panel 23 effectively purifies the gas to protect the working environment and personnel health.

[0029] See also Figure 3 , a motor 18 is provided on the front side of the transmission chamber 10 , and the motor 18 provides power for the rotation of the double-threaded transmission rod 11 ;

[0030] See also Figure 3, the output end of the motor 18 is installed with a first rotating shaft 14 through a coupling, and the first rotating shaft 14 is rotatably connected to the transmission chamber 10, and a second rotating shaft 15 is provided on both sides of the first rotating shaft 14, and the front end of the double-threaded transmission rod 11 is welded with a third rotating shaft 16, and the third rotating shaft 16 is rotatably connected to the transmission chamber 10, and the outer walls of the first rotating shaft 14 and the third rotating shaft 16 and the two ends of the second rotating shaft 15 are provided with bevel gears 17, and the bevel gears 17 are meshed with each other.

[0031] See also Figure 3 , bearings 19 are provided on both sides of the outside of the second rotating shaft 15, the inner walls of the bearings 19 are connected to the outer walls of the second rotating shaft 15, and the outer walls of the bearings 19 are connected to the inner walls of the transmission cavity 10.

This design is not only simple and quick to operate, but also can flexibly adjust the clamping force according to actual needs, thereby ensuring the stability and safety of the steel structure during the welding process;

[0034] See also Figure 1 and Figure 4An air suction machine 5 is provided on one side of the purification box 4. The air suction machine 5 is connected to the purification box 4 and the smoking hood 7 through a connecting pipe 6. The air suction machine 5 can generate a strong suction force and quickly suck the harmful smoke generated during welding into the purification box 4 through the connecting pipe. The activated carbon air purification plate 23 inside the purification box 4 can effectively adsorb and purify these harmful gas molecules, thereby preventing them from escaping into the working environment and causing harm to the operators.

The third rotating shaft 16 will drive the rotation of the double-threaded transmission rod 11, and the double-threaded transmission rod 11 will drive the synchronous rotation of the two moving seats 13. Since the moving seats 13 are slidably matched with the two guide rods 12, they will be subject to axial limitation. The two moving seats 13 will rotate in opposite or opposite horizontal straight lines. The two When the movable seat 13 moves toward each other, it can synchronously push the placed steel structure, so that the two steel structures can be docked more accurately. After the two steel structures are docked, the knob 22 can be turned, and the knob 22 will drive the single-threaded rod 20 to rotate, and the single-threaded rod 20 will drive the pressure plate 21 to move down, so that the steel structure can be clamped and fixed, thereby avoiding the movement of the steel structure during welding, ensuring the stability and accuracy of the welding process, starting the electric telescopic rod 3 to move the lifting platform 2 downward, starting the electric slide rail to move the welding mechanism 9 for welding processing, starting the suction machine 5 during welding, and the suction machine 5 can generate suction in the fume hood 7 through the connecting pipe 6, so that the harmful smoke emitted during welding can be sucked into the interior of the purification box 4, and the interior of the purification box 4 is provided with an activated carbon air purification plate 23, which can adsorb harmful gas molecules to achieve a purification effect, avoid polluting the working environment, and ensure the health of the operator.
