Abstract

The invention provides a pipeline, a pipeline preparation method and concrete machinery. The pipeline comprises a pipe body and a wear-resisting coating; the wear-resisting coating is formed in the inner wall of the pipe body through heat spray coating; and the wear-resisting coating comprises a ceramic coating. Through the arrangement of the wear-resisting coating, materials can be prevented fromdirectly impacting and wearing the pipe body, so the pipe body is protected from wear by the materials and the service life of the pipe body is prolonged; and the pipe body can be prepared from regulate metal other than wear-resisting alloys, so the weight and production cost of the pipe body are lowered. The wear-resisting coating is of an integral structure formed by heat spray coating; on theone hand, the integral structure is high in structural stability, structural connection fracture does not exist, and the phenomenon of structural damage or falling can be effectively avoided; and on the other hand, heat spray coating technology has the advantages of high forming efficiency and high stability, so the pipeline production cost can be lowered while structural stability of the wear-resisting coating can be further improved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a pipeline, a method for preparing the pipeline and a concrete machine. Background technique [0002] In the current concrete pipeline, the inner layer of the double-layer pipe body is made of wear-resistant metal to reduce the abrasion of the concrete on the pipeline. However, the inner layer of the pipe is made of wear-resistant alloy, which has the problems of heavy weight and low service life. [0003] Therefore, how to design a conveying pipeline with lighter weight and stronger wear-resisting life has become a technical problem to be solved urgently. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0005] To this end, a first aspect of the invention provides a pipeline. [0006] A second aspect of the present invention provides a method for preparing a ...
