Description

Technical Field

[0001] This utility model relates to the field of steel structure painting technology, and in particular to a steel structure painting device. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are primarily composed of steel beams, columns, trusses, and other components made of shaped steel and steel plates, and undergo rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, steel structures are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields.

[0003] Before use, steel structures need to be painted. Painting forms a protective film on the steel surface, isolating the steel from direct contact with the external environment, thus slowing down or preventing rusting. A good anti-corrosion coating can protect the steel from corrosive media, reducing maintenance costs and replacement frequency. During the painting process, some steel structures are not straight, while others are curved. The painting position needs to be constantly adjusted, which increases the intensity of the painting work. If the painting area is increased, paint will be wasted. Therefore, a steel structure painting device is proposed. Utility Model Content

When blocked, the paint sprayed by the nozzle 9 will be located in the collection groove 14. An inclined flow groove 17 is set at the bottom of the collection groove 14. The collected paint slides to the lowest point and flows out from the collection pipe 18 into the collection box 19, thus realizing the collection of paint.

[0024] In use: During the painting process, the steel structure body 3 is conveyed by the conveyor belt 2. Two rotating contact wheels 13 are located on both sides of the steel structure body 3. By moving the rotating contact wheels 13, the position of the anti-spray box 10 can be adjusted. By moving the anti-spray box 10, the spray range of the nozzle 9 can be controlled. The nozzle 9 blocked by the anti-spray box 10 will not spray any paint. Thus, it can follow the width of the steel structure body 3 and adaptively adjust the range of paint spraying, so as to effectively paint the steel structure body 3 and avoid the situation of spraying paint in other areas and wasting paint. The paint sprayed by the nozzle 9 after being blocked will be located in the collection tank 14. The bottom of the collection tank 14 is provided with an inclined flow channel 17. The collected paint slides to the lowest point and flows out from the collection pipe 18 into the collection box 19 to realize the collection of paint.
