Abstract

The invention discloses a joint arm of a cloth arm bracket and a manufacturing method thereof and also relates to a concrete conveying machine provided with the joint arm. The joint arm of the cloth arm bracket comprises a transverse plate and a vertical plate, wherein in the longitudinal direction, the transverse plate and the vertical plate extend along the same direction; in the transverse section, the transverse plate extends horizontally, and the vertical plate extends vertically; the side of the vertical plate has flanging, and the side of the vertical plate and the horizontal flanging are fixed with the transverse plate; and the transverse plate and the vertical plate are respectively provided with a composite material layer which comprises resin and fiber. The joint arm can maintain less weight while ensuring higher strength and fatigue resistance, and also can reduce the adverse effect for the joint arm caused by welding; furthermore, the joint arm provided by the invention also has damping performance and corrosion resistance, thus prolonging the service life of the joint arm.

Description

technical field

[0001] The invention relates to a distribution boom technology for conveying concrete, in particular to a joint arm of a distribution boom and a manufacturing method of the joint arm, and also relates to a concrete conveying machine with the joint arm. Background technique

[0002] At present, when carrying out construction operations, concrete is generally delivered by a concrete pump truck or a concrete distribution rack. In the process of conveying concrete, the concrete pump provides appropriate power to make the concrete slurry reach the predetermined place through the conveying pipeline under appropriate pressure, so as to perform concrete pouring or pouring operations at a position far away from the mixing station. The conveying pipeline is formed by connecting several conveying pipes in sequence.

[0003] The conveying pipeline is generally supported by a cloth boom. Such as figure 1 As shown, this figure is a structural schematic diagram of a fabr...
