Description

Technical Field

[0001] The utility model relates to the technical field of steel tower and steel box girder bridge construction, in particular to a magnetic carbon arc gouging dust collecting device. Background Art

[0002] When steel structure products are manufactured in the factory, considering the risks and difficulty of bridge construction, they are usually shipped to the bridge site for erection after the topcoat is completed in the factory. At this time, the finished paint surface needs to be fully protected to reduce paint damage. Carbon arc gouging is a method of surface processing grooves that uses carbon rods or graphite rods as electrodes to generate an arc between the workpiece, melt the metal, and blow away the molten metal with compressed air.

[0003] In welding production, it is mainly used for gouging, eliminating weld defects and back cleaning. Carbon arc gouging uses the arc heat generated between the carbon rod and the workpiece to melt the metal, and at the same time uses compressed air to blow away the molten metal. Therefore, during the carbon arc gouging construction, its strong blowing force will cause a large range of slag splashing and dust pollution, resulting in large-scale damage to the painted surface.

[0004] At present, when carbon arc gouging is used to gouge the transverse weld seams of steel bridges, magnets are often used to attach the open dust collecting box to the surface of the steel structure. Although this operation method is simple and easy, the actual protection effect is very limited. First, the magnet is adsorbed on the steel structure through the dust collecting box, and it is close to the weld for a long time. Severe heat will cause the magnetic force to decay and the dust collecting box to fall. Then, when gouging the transverse weld seams, the waste slag will fly to both sides, and it is difficult for the bottom dust collecting box to effectively collect it. Utility Model Content

[0005] The utility model aims to provide a magnetic carbon arc gouging dust collecting device, which solves the technical problems in the prior art that the dust collecting box has weak adsorption force and cannot collect waste residue well.

The beneficial effect of adopting this step is that the fireproof cotton can prevent slag from splashing and avoid deformation of the box body.

[0015] Furthermore, at least one reinforcing rib plate is provided on the inner side of the assembly section. The beneficial effect of adopting this step is that the strength of the box body can be ensured by the reinforcing rib plate.

[0016] Furthermore, the height of the slag blocking section is greater than the height of the assembly section. The beneficial effect of adopting this step is that the slag blocking section can better block the slag.

[0017] Furthermore, the box body is made of a steel plate cut in one piece and then bent and welded. The beneficial effect of adopting this step is that it is easy to process.

[0018] Furthermore, the thickness of the steel plate is 0.5 mm or 0.8 mm. The beneficial effect of adopting this step is to ensure the strength of the box body.
