[0021] The following combination Figure 1 and Figure 2 The utility model is described in detail.

[0022] Example

[0023] A smokeless steel structure welding device includes a mounting frame 2, on which several load-bearing rollers 1 are rotatably mounted. The mounting frame 2 is provided with at least two sets of clamping devices. The clamping devices include forward and reverse screws 3 and guide rods 5, which are axially arranged along the load-bearing rollers 1. The forward and reverse screws 3 are rotatably connected to the mounting frame 2 and are connected to a motor 14. Clamps 4, which are slidably connected to the guide rods 5, are threadedly connected at both ends of the forward and reverse screws 3. A portal frame 9 is mounted on the mounting frame 2, and a transverse movement device 8 is provided on the portal frame 9. The transverse movement device 8 is connected to a vertically mounted telescopic device 7. The telescopic end of the telescopic device 7 is connected to a mounting plate 10. A welding head 6 and a smoke extraction device are mounted on the mounting plate 10. The guide rods 5 are fixedly connected to the mounting frame 2.

[0024] The steel structure is assisted in conveying by the carrying roller 1, and the two steel structures can move relative to each other to reach the designated welding point. Then the two clamping plates 4 clamp the steel structure to the middle position to align the two steel structures, reducing the workload of manual adjustment; the transverse device 8 drives the welding head 6 and the smoke suction device to move synchronously to perform automatic welding and smoke suction at the same time.

[0025] The telescopic device 7 can raise and lower the welding head 6 and the fume extraction device to accommodate welding of steel sections or steel plates. The telescopic device 7 can be a hydraulic or electric telescopic rod. The transverse movement device 8 is conventional and includes a sliding seat slidably mounted on a portal frame 9. The sliding seat is equipped with rollers that contact the portal frame 9. The rollers are driven by a drive motor to rotate, thereby achieving movement of the sliding seat.

[0026] The smoke extraction device includes a support rod 11 connected to a mounting plate 10. A suction hose 12 is fixed to the support rod 11, and a suction hood 13 is provided at the end of the suction hose 12. The suction hose 12 is connected to a suction pump and a smoke treatment device (not shown in the figure), such as a dust removal device or a water tank, wherein the water tank directly washes the smoke with water to perform dust removal.

[0027] The support rod 11 is made of plastic. When the support rod 11 bends, the suction hose 12 bends accordingly, adjusting the position of the suction hood 13 to better adapt to different usage scenarios. The plastic support rod 11 can be made of iron or copper wire. The suction hose 12 can be connected to the plastic support rod 11 by bundling, facilitating subsequent replacement of the suction hose 12.

[0028] The sidewalls of the mounting frame 2 are provided with horizontal slide grooves 16, and the portal frame 9 is slidably arranged in the slide grooves 16. The portal frame 9 is slidably connected to the mounting frame 2 via the slide grooves 16, so that the position of the portal frame 9 can be adjusted, so that the welding position of the welding head 6 can be adjusted along the length of the mounting frame 2, thereby avoiding the need to move the steel structure to adjust the welding position, which is convenient and quick.

[0029] The screw thread on the portal frame 9 is penetrated with a screw rod 15 that abuts against the side walls of the mounting frame 2. After the screw rod 15 is tightly against the side wall of the mounting frame 2, the movement of the portal frame 9 can be restricted to ensure the stability of welding.

[0030] The plurality of bearing rollers 1 are divided into two groups, and the two groups of bearing rollers 1 are arranged at intervals. The portal frame 9 is located between the two groups of bearing rollers 1 so that the welding head 6 does not damage the bearing rollers 1 during welding.

[0031] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
