Description

Technical Field

[0001] The utility model relates to the technical field of steel spraying, in particular to an automatic spraying device for H-shaped steel. Background Technique

[0002] The H-shaped steel is an economic section high-efficiency profile with optimized cross-sectional area distribution and reasonable strength-to-weight ratio. Its name comes from the similarity between its cross-sectional shape and the English letter "H". The cross-section of the H-shaped steel mainly consists of two parts, namely the web and the flange plate, which are usually called the waist and the side. The H-shaped steel structure has good stability and is widely used in the fields of civil and industrial buildings. Before leaving the factory, the H-shaped steel often needs to be sprayed on the surface, and a specific coating is sprayed on the surface of the H-shaped steel to play a role in decoration, anti-corrosion and improving durability.

[0003] The H-shaped steel is relatively heavy, and it needs to be turned over during the spraying process, making the spraying process of the H-shaped steel more cumbersome, resulting in low spraying efficiency of the H-shaped steel and delaying the subsequent processing of the H-shaped steel. To improve the spraying efficiency of the H-shaped steel, we designed an automatic spraying device for H-shaped steel. Content of the Utility Model

[0004] The purpose of the utility model is to provide an automatic spraying device for H-shaped steel to solve the problems put forward in the above background technique.
