[0002] H type steel plate is a long strip steel material like letter "H", plays a vital role in building and bridge engineering. Compared with traditional I-beam, the flange of H type steel is wider and parallel, which makes it perform well in mechanical properties and construction performance. H type steel has high bending and compression strength, can bear larger load, while under the same bearing condition, its weight is lighter than traditional steel, helps to reduce the overall structure weight. In order to increase its service life, the surface of existing H type steel plate needs to be painted during production and processing.

[0003] In the contrast file of a kind of paint spraying device for H type steel plate disclosed in CN217796829U, it is specifically proposed that "the support frame is slidably connected with the door type support at both ends, the inner side paint spraying assembly is arranged on the horizontal plate of the door type support, the paint spraying pipes in the inner side paint spraying assembly respectively face the adjacent right angle inner wall surface of the H type steel plate to be painted, the two paint spraying pipes are acute angle, the paint spraying pipe tail end is fixed with paint spraying nozzle one, the two paint spraying nozzles one on one side respectively face the adjacent two side surfaces of the single side right angle of the H type steel plate to be painted, the two side vertical plates of the door type support are provided with outer side paint spraying assembly relative to inner wall".
