A painting device for steel structure maintenance

Abstract

The invention belongs to the technical field of painting equipment, in particular to a painting device used for steel structure maintenance. For columnar steel structure parts, since the surface wall is curved, it is difficult to control the surface painting thickness by directly using a spray gun to paint, resulting in In case of unevenness after painting, the following scheme is proposed, including a paint box, a central shaft is fixedly connected between the inner walls of the two sides of the paint box, and a roll is movably connected to the outer wall of the central shaft. Both ends of the receiving cylinder are provided with annular grooves, and both ends of the central shaft are movably connected with coil springs, and the two ends of the coil springs are respectively fixedly connected with the inner wall of one side of the annular groove and the inner wall of one side of the paint box. The interior of the paint box is provided with a conveying assembly. The invention uses the cloth to paint the surface of the steel structure, and uses the softness of the cloth to fit the surface wall of the steel structure, so that the paint is more uniform on the surface of the steel structure during the painting operation, and the effect after painting 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...

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
