Description

Technical Field

[0002] Steel pipes are widely used in engineering fields such as tap water, natural gas, petroleum, chemical industry, medicine, communication, electricity, and ocean. In order to enhance the strength and corrosion resistance of steel pipes, it is usually necessary to coat the inner wall or / and outer wall of the steel pipe with plastic. Before coating, the steel pipe usually needs to be cleaned, that is, to remove debris, oxide scale, welding slag, sticky sand, dirt and other attachments on the surface of the steel pipe, so that the inner and outer wall surfaces of the steel pipe have a uniform roughness, enhance the adhesion and corrosion resistance of the surface coating during spraying, and also improve the fatigue strength of the steel pipe.

[0003] The process of sandblasting steel pipes includes a steel pipe feeding process, which refers to continuously sending the steel pipes to be cleaned to the inner sandblasting position of the steel pipe inner wall sandblasting cleaning equipment. In the prior art, a crane is used to lift the steel pipes and lift them to the inner sandblasting position of the steel pipe cleaning equipment. This feeding method not only has low feeding efficiency, but also cannot ensure the flatness of the pipes. At the same time, the steel pipes may slip off the lifting device during lifting, which poses a risk of injuring workers and safety hazards. Therefore, it is necessary to design an automatic feeding device to solve the above problems and improve production efficiency. Utility Model Content
