Lacquering device for steel structure maintenance

Abstract

The invention belongs to the technical field of lacquering equipment, particularly relates to a lacquering device for steel structure maintenance, and provides the following scheme for the condition that due to the fact that the surface wall of a columnar steel structure part is a curved surface,the paint spraying thickness of the surface is very difficult to control when a spray gun is directly adopted for lacquering, and consequently,non-uniformity occurs after paint spraying. The lacquering device for steel structure maintenance comprises a lacquering box; a center shaft is fixedly connected between the inner walls of the two sides of the lacquering box; a rolling cylinder is movably connected to the outer wall of the center shaft; annular grooves are formed in the two ends of the rolling cylinder correspondingly; coil springs are movably connected to the two ends of the center shaft correspondingly; the two ends of each coil spring are fixedly connected with the inner wall of one side of the corresponding annular groove and the inner wall of one side of the lacquering box correspondingly; and a conveying component is arranged in the lacquering box. According to the lacquering device for steel structure maintenance, the surface of the steel structure is lacquered through the cloth, and the cloth can be attached to the surface wall of the steel structure conveniently due to the soft characteristic of the cloth, so that paint is more uniform on the surface of the steel structure during lacquering operation, and the effect after lacquering is improved.

Description

technical field [0001] The invention relates to the technical field of painting equipment, in particular to a painting device used for steel structure maintenance. Background technique [0002] Painting is essentially spraying, which is dispersed into uniform and fine droplets by means of pressure or centrifugal force through a spray gun or disc atomizer, and applied to the surface of the object to be coated, which can be divided into air spraying , airless spraying, electrostatic spraying and various derivatives of the above basic spraying forms. [0003] The role of steel structure spraying is to have protection and prolong the service life of the workpiece, followed by decoration to achieve a suitable appearance effect, and thirdly to achieve special performance for special purposes, such as sound insulation, heat insulation and fire prevention. [0004] During the continuous use of the steel structure, the original protective layer on the surface will fall off, and it n...

AI Technical Summary

Problems solved by technology

[0004] During the continuous use of the steel structure, the original protective layer on the surface will fall off, and it needs to be painted to improve its service life. At present, the method of direct spraying with a spray gun is often used for columnar steel structure components. For curved surfaces, it is difficult to control the thickness of the paint on the surface by directly painting with a spray gun, resulting in unevenness after painting
