Technical Field

[0001] The utility model relates to the technical field of spraying devices, in particular to an anti-corrosion spraying device for the surface of steel structures. Background Art

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates. Most of the surfaces of steel structures are sprayed with anti-corrosion coatings before use.

[0003] In the prior art, before the production of bridge steel structures, it is necessary to spray anti-corrosion coatings on their surfaces. However, most bridge steel structures are large in volume. Commonly used spraying devices are mostly a spray gun and an air compressor in cooperation. Workers hold the spray gun to carry out spraying work. Workers need to move back and forth and need to use tools such as ladders to spray high places, which is rather troublesome and affects work efficiency.

[0004] Therefore, an anti-corrosion spraying device for the surface of steel structures is proposed to solve the above problems. Summary of the Utility Model
