Description

Technical Field

[0001] The present application relates to the field of spraying technology, and more specifically, to a device for spraying an anti-corrosion layer on a steel structure. Background Art

[0002] Anti-corrosion spraying is a widely used surface coating technology, and its main purpose is to protect the surface of metal or other materials from corrosion and oxidation. In the production of steel structure materials, it is necessary to carry out anti-corrosion spraying on their surfaces. The prior art patent document with publication number CN212418440U provides a spraying device for anti-corrosion steel structure coating. The device installs sliding plates on the side plates and the top plates, and is connected by a screw rod. The sliding plates can be driven to slide along the groove square, thereby reducing the use of nozzles and improving resource utilization. By arranging a transmission gear at the rear end of the connecting pipe, the nozzle connected to the front end can be mobilized to rotate, which is convenient for spraying steel components from multiple angles and improving the uniformity and efficiency of spraying.

[0003] In view of the above-mentioned related technologies, the inventor believes that although the spray head of the device can be raised and lowered and its angle can be adjusted, the side of the steel structure in contact with the conveyor belt cannot be sprayed, which limits the spraying range and requires secondary spraying, which is inefficient. Therefore, we propose a steel structure anti-corrosion layer spraying device. Utility Model Content
