Problems solved by technology

[0005] At the same time, due to the need to set up a steel wire structure to increase the mechanical strength of the end hose, this also causes the weight of the end hose to be too large, which affects the operation of the output port of the end hose

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 limit the protection scope of the present invention in any way.

[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 pipe body 100 and a fiber reinforced layer 200; wherein the pipe body 100 is a polyurethane elastomer formed of polyurethane material; the fiber reinforced layer 200 is compounded on the outer wall of the pipe 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

The invention discloses a concrete transporting machine, an end hose of a cantilever crane system thereof and a preparation method of the end hose. The end hose of the cantilever crane system, which is disclosed by the invention, comprises a hose body and a fiber reinforcing layer compounded on the outer surface of the hose body; the material of the hose body comprises polyurethane, and the fiberreinforcing layer comprises glass fibers and / or carbon fibers; and preferentially, the fiber reinforcing layer is compounded on the outer surface of the hose body through a coupler. Because the polyurethane has stronger wear resistance, the wear rate of the hose body of the end hose is lower; moreover, the chemical property of the polyurethane is more stable, and influences due to external environment and temperature change on the properties of the end hose can be reduced, so that the end hose has longer service life; and in addition, the strength of the end hose is guaranteed through the fiber reinforcing layer consisting of the glass fibers and / or the carbon fibers to meet the requirements on transporting materials and controlling a delivery outlet, so that the end hose has lighter weight, which is also beneficial to controlling and operating the end hose.

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...
