Abstract

The invention provides a work arm assembly and excavating equipment. The work arm assembly comprises a work arm, a first hydraulic cylinder, a rotary device and a pitching device. The work arm comprises multiple unit arms. The first hydraulic cylinder is connected with two adjacent unit arms in the multiple unit arms, and the swing angle between the two adjacent unit arms can be adjusted. The rotary device is connected with the work arm, and can drive the work arm to rotate. The pitching device is connected with the rotary device, and can adjust the first tilt angle of the rotary device relative to the pitching device. According to the work arm assembly, the position of the rotary device is adjusted through the pitching device; and after the rotary device drives the work arm to rotate by aproper angle, the swing angle between the two adjacent unit arms is adjusted through the first hydraulic cylinder, and therefore the unit arms connected with a work device in the multiple unit arms can be attached to a lateral wall and / or a bottom plate of a roadway well, roadway repairing work under the special working condition can be carried out, and the application range of the product is widened.

Description

technical field [0001] The invention relates to the technical field of excavating equipment, in particular to a working arm assembly and an excavating equipment. Background technique [0002] With the development of production activities in the roadway, the bottom drum and side wall deformation will occur in the roadway. Therefore, it is necessary to carry out roadway repair operations such as undercover, side expansion, and ditches in a timely manner. If relying on manual labor to operate, the work efficiency is low, the labor intensity of the workers is high, and there is a large potential safety hazard. If mechanical equipment is used for operation, the operation effect is not ideal because the working arm of the current excavating equipment cannot fit well with the roadway side and / or the bottom plate. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] To thi...
