Material conveying machine, composite structure conveying pipe and manufacture method thereof

Abstract

The invention discloses a composite structure conveying pipe and a manufacture method of the conveying pipe. The composite structure conveying pipe comprises an outer pipe and an inner pipe, wherein the outer pipe is made of a light alloy material; the inner pipe is made of a light wear-resistant material; and the inner pipe is arranged in the outer pipe. In addition, the invention also discloses a material conveying machine including the composite structure conveying pipe. According to the invention, the outer pipe of the composite structure conveying pipe made of the low-density, high-strength and high-toughness material can provide enough strength and toughness at a lighter weight so as to prevent deformation and burst of the conveying pipe, and has higher shear resistance, less possibility of damages caused by bumping or dropping and lower cost in comparison with the composite material; and the inner pipe made of the light wear-resistant material can provided enough wear resistance at a lighter weight. Therefore, the overall weight of the product is reduced by more than 50% in comparison with that of a steel conveying pipe so as to facilitate assembly and disassembly, greatly improve efficiency and safety and simplify the process, and subsequent heat treatment for the inner layer is obviated.

Description

technical field [0001] The present invention relates to material conveying related technologies, in particular to a composite structure conveying pipe, and also relates to a manufacturing method of the composite structure conveying pipe and a material conveying machine using the composite structure conveying pipe. Background technique [0002] The conveying pipe is an indispensable accessory for material conveying equipment (such as concrete pump trucks, distributors, etc.). Materials include concrete, etc. Only through continuous transmission through the conveying pipe can long-distance normal conveying be achieved. [0003] Conveyor pipes generally require high wear resistance on the inner wall and good toughness as a whole. In addition, the weight should not be too heavy, otherwise the equipment with weight restrictions will be overweight, and it will also cause difficulty in disassembly and assembly, which will affect the work. Efficiency and low security. [0004] At p...
