Problems solved by technology

[0006] In the folding boom, when the main structure of the boom (that is, the beam structure) is made of fiber composites, the connection between the boom section and the boom section or the connection between the boom section and the driving element is complex due to the load and the rotational friction , there are problems of low connection fatigue life and insufficient reliability

Embodiment Construction

[0075] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0076] In the present invention, unless stated to the contrary, the used orientation words such as "up, down, left, and right" generally refer to up, down, left, and right referred to with reference to the drawings. "Inner and outer" refer to inner and outer relative to the outline of the part itself.

[0077] refer to figure 1 , the folding boom includes several boom sections connected in series in sequence. In order to realize the folding and unfolding of the folding boom, at least one end of one boom section must have an elbow structure between two adjacent boom sections. Generally speaking, at least one end of each arm section in the folding arm frame has ...

Abstract

The invention relates to the field of multi-joint booms, and discloses a beam structure, a boom section, a boom, mechanical equipment and a manufacturing method of the boom section. The beam structurecomprises a fiber composite material layer part and metal connecting linings pre-buried in a connecting portion of the fiber composite material layer part; the plurality of layers of metal connectinglinings are arranged in the wall thickness direction of the fiber composite material layer part, and every two adjacent layers of metal connecting linings are spaced through a fiber composite layer of the fiber composite layer part, so that the stress uniformity of the connecting portion in the wall thickness direction is improved. According to the technical scheme, the connection reliability ofthe connection portion of the beam structure can be favorably improved, and the connection service life can be favorably prolonged.

Description

technical field [0001] The present invention relates to the field of multi-joint booms for mechanical equipment, and in particular to a beam structure. Further, the invention also relates to a boom section, a boom frame, a mechanical device and a method for manufacturing the boom section. Background technique [0002] The multi-joint boom is usually composed of multiple boom sections connected in sequence, and the adjacent parts can be used as fulcrums between two adjacent boom sections to generate relative rotation. Multi-joint booms can be widely used in various fields, such as robot booms, observation equipment supports, construction machinery and equipment, etc. [0003] As a typical multi-joint boom, the folding boom is a key operating component of construction machinery such as concrete pump trucks, fire trucks, and excavators, and determines the performance of the main engine of construction machinery and equipment. [0004] With the rapid development of economic con...
