Embodiment Construction
[0039] The present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the protection scope of the present invention.
[0040] Please refer to figure 1 , which is a schematic structural view of the terminal hose of a boom system provided by the present invention.
[0041] The terminal hose includes a tube body 100 and a fiber reinforced layer 200; wherein the tube body 100 is a polyurethane elastomer formed of polyurethane material; the fiber reinforced layer 200 is compounded on the outer wall of the tube body 100, and the fiber reinforced layer 200 can be formed by glass fibers , can also be formed of carbon fiber to ensure the strength of the end hose and improve the tear resistance and tensile performance of the end hose. At the same time, because the polyurethane material has strong wear resistance, fatigue resistance and vibration resist...

Abstract
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.
Description
technical field [0001] The invention relates to a technology for conveying concrete or materials similar to concrete, in particular to an end hose of a boom system and a preparation method for the end hose, and also relates to a concrete conveying machine including the end hose. Background technique [0002] Concrete pump trucks are currently widely used concrete conveying machinery. Concrete pump trucks include a boom system that delivers concrete to a predetermined location. The boom system generally includes a plurality of joint arms; the multiple joint arms are hinged sequentially through the transverse hinge shaft; a driving mechanism is provided between two adjacent joint arms, and the driving mechanism can drive the adjacent joint arms to rotate relatively, so that Adjust the position of the output port of the last section arm. In order to conveniently control the position of the output port of the boom system, a terminal hose is also provided outside the output por...
