[0024] The following is combined with Figure 1-2 This application is described in further detail.

[0025] The present application discloses a welding fume purification device.

[0026] Reference Figure 1 and Figure 2 A welding fume purification device comprises a machine body 1 and a suction bucket 2 arranged on the machine body 1, wherein the suction bucket 2 is fixed to the machine body 1 through a suction arm, and the machine body 1 is used to be erected on a pipeline 3 in a pipe gallery.

[0027] After the machine body 1 is erected on the pipeline 3, in order to ensure the stability of the machine body 1, two sets of supporting mechanisms are installed on the machine body 1. The supporting mechanisms include two legs 4 and a driving assembly that drives the two legs 4 to move closer to or away from each other. The two legs 4 in the supporting mechanisms are respectively arranged on both sides of the machine body 1 in the length direction of the pipeline 3.

[0028] The driving assembly includes a handle 5 and a bidirectional screw 6. A slider 7 is fixedly connected to the upper end of the leg 4. The slider 7 can slide horizontally on the upper surface of the body 1, that is, the lower surface of the slider 7 is a plane, and the lower surface of the slider 7 abuts against the upper surface of the body 1. The bidirectional screw 6 is used to pass through two sliders 7 at the same time, and the two sliders 7 are respectively threadedly connected to the two sections of the reverse thread lines of the bidirectional screw 6. The handle 5 is fixed to one end of the bidirectional screw 6 and is used to drive the bidirectional screw 6 to rotate.

[0029] In another embodiment, the distance between the two legs 4 can also be adjusted by using a cylinder.

[0030] In this embodiment, the leg 4 is a multi-stage telescopic rod, and the body 1 is provided with an adjusting member for adjusting the length of the leg 4. The leg 4 includes a plurality of telescopic sections 8, and the plurality of telescopic sections 8 are sequentially connected end to end. The telescopic sections 8 are in the shape of a circular tube, and the cross-sectional diameters of the plurality of telescopic sections 8 gradually decrease from close to the base to away from the base, that is, among the plurality of telescopic sections 8, the telescopic section 8 with the largest cross-sectional diameter is fixed on the body 1, and the telescopic section 8 with the smallest cross-sectional diameter is farthest away from the body 1. The slider 7 is installed on the telescopic section 8 with the largest cross-sectional diameter, and a support plate 9 is installed at the lower end of the telescopic section 8 with the smallest cross-sectional diameter, and a roller 14 is installed on the support plate 9.

[0031] An air passage 10 is opened in the telescopic section 8, and the air passages 10 of adjacent telescopic sections 8 are connected, and both ends of the legs 4 are closed. The adjusting part includes an air pump 11, and the air pump 11 is fixed on the body 1. The air outlet of the air pump 11 is connected to the telescopic section 8 with the largest cross-sectional diameter through a hose.

[0032] Adjacent telescopic sections 8 are restricted from separation by an anti-slip structure, and the anti-slip mechanism may be an anti-slip block 12, that is, except for the telescopic section 8 with the largest cross-sectional diameter, anti-slip blocks 12 are fixed on the outer walls of other telescopic sections 8, and then a slide groove 13 for the anti-slip block 12 to slide is provided on the inner wall of the corresponding telescopic section 8.

[0033] In another embodiment, the length of the leg 4 can also be adjusted manually, that is, using a tightening screw. In actual use, the tightening screw is rotated to increase the sliding resistance of the telescopic section 8, so that the length of the leg 4 can be positioned.

[0034] The implementation principle of a welding fume purification device disclosed in the present application is: when in use, the handle 5 and the bidirectional screw 6 are used to adjust the distance between the two groups of support mechanisms, and then the body 1 is erected on the pipeline 3, and the position of the suction bucket 2 is adjusted. Then, the air pump 11 is used to adjust the length of the support leg 4 so that the roller 14 on the support leg 4 can be supported on the bottom surface of the pipe gallery. When welding the pipeline 3, the body 1 is moved to the welding position, and the suction bucket 2 is used to absorb and purify the welding fume.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
