Description

Technical Field

[0001] The utility model relates to the technical field of steel structure spraying equipment, in particular to intelligent spraying equipment for anti-corrosion coatings on steel structures. Background Art

[0002] For the anti-corrosion treatment of steel structures, there are a variety of spraying equipment available in the prior art. For example, the patent document with application number 202321471589.4 proposes "a spraying device for steel structure processing and maintenance, including: a spray box, push handles arranged on both sides of the top of the spray box, a movable base arranged at the bottom of the spray box, a spray assembly arranged inside the spray box, used for spraying and maintaining the steel structure, and a stirring assembly arranged inside the spray box, used to prevent the paint inside the spray box from solidifying". After implementation, "the spray assembly can be used to spray paint and maintain the surface of the steel structure to prevent rust on the surface of the steel structure and extend the service life of the steel structure. It solves the problem that manual back spraying is time-consuming and labor-intensive, resulting in low maintenance work efficiency. The paint can be stirred and agitated through the stirring assembly, so that the paint has good fluidity, ensuring that the paint can be evenly sprayed onto the steel structure to avoid affecting the maintenance spraying quality."
