TERMINAL FLEXIBLE PIPE FOR CANTILEVER SYSTEM OF CONCRETE CONVEYING MACHINE AND METHOD OF MAKING THE SAME, AS WELL AS THE CONCRETE CONVEYING MACHINE

摘要

Disclosed are a terminal hose for cantilever system of a concrete conveying machine and a method of making the same, as well as the concrete conveying machine. The terminal hose includes a hose body (100) and a fiber reinforced layer (200) combined on the outer surface of the hose body (100) via a coupling agent, wherein the hose body (100) consists of polyurethane and composite metal oxide Sr₂Ta₂O₇, and the fiber reinforced layer (200) comprises glass fibers and/or carbon fibers. The advantages of the invention are as following: owing to the polyurethane material has strong wear resistance and stable chemical performance, the wear rate of the hose body (100) is lower and the effects of an external environment and temperature change on performance of the terminal hose are reduced, thus the terminal hose has prolonged service life, and the fiber reinforced layer (200) formed by the glass fibers and/or carbon fibers guarantees the strength of the terminal hose and reduces the weight of the terminal hose, so a control operation of the terminal hose is met when conveying material.
