Description

Technical Field

[0001] The present application relates to the technical field of spraying equipment, and in particular to a spraying device for steel structures. Background Art

[0002] Steel structure is a structural system mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. It is widely used in large factories, venues, super high-rise buildings and other fields due to its light weight, high strength, good seismic performance, short construction period and convenient maintenance and management. However, based on the usage scenarios of steel structures and their own material characteristics, they are prone to rust and corrosion. In order to extend the service life of the steel structure, a layer of anti-rust paint is generally attached to the surface of the steel structure.

[0003] Since the spatial size of the steel structure is large, the immersion method of attaching anti-rust paint consumes more paint, so spraying is often used for attaching anti-rust paint. The prior art discloses a spraying device for steel structures, which includes a spraying chamber, wherein the interior of the spraying chamber and the left and right sides of the spraying chamber are respectively provided with transportation devices for transporting the steel structure, a sliding feed rack is provided above the transportation device, and the steel structure is supported and fixed above the feed rack, the spraying chamber is provided with an opening for allowing the feed rack equipped with the steel structure to pass through, and a spray gun mechanism is provided inside the spraying chamber; the spray gun mechanism includes a bracket fixedly arranged with the transportation device inside the spraying chamber, the bracket is provided with a rotatable spray gun, and the spray gun includes a first spray gun for spraying the lower bottom surface of the steel structure, a second spray gun for spraying the upper bottom surface of the steel structure, a third spray gun for spraying the left side of the steel structure, and a fourth spray gun for spraying the right side of the steel structure.

[0004] With regard to the above-mentioned related technologies, when spraying paint on a steel structure, it is necessary to first lift the steel structure by lifting equipment or manually and then lay it flat, and then place it on a transport device. After the painting is completed, in order to avoid causing large-area damage to the anti-rust paint during the lifting process, it is necessary to wait for the anti-rust paint to solidify before spraying the next steel structure again, which makes the use efficiency of the spraying device low.
