Work machine

Abstract

The invention provides an operation machine. The operation machine comprises a vehicle body, a rotary table, an arm frame and a luffing mechanism. A rotary assembly positioned behind the cab is mounted on the vehicle body; the rotary table is installed on the rotary assembly and comprises a hinge arm, the hinge arm can rotate to the position above the cab, and a first hinge structure and a second hinge structure are arranged on the hinge arm. The eccentric distance of at least one of the first hinge structure and the second hinge structure relative to the rotation axis of the rotary table is larger than the distance between the rear end of the cab and the rotation axis. The first hinge structure is hinged to the end of the arm support, the second hinge structure is hinged to one end of the luffing mechanism, and the other end of the luffing mechanism is hinged to the middle of the arm support. Based on eccentric arrangement of the rotary table, the arm support can rotate to the position above the cab along with the hinged arm, effective utilization of the spare space above the cab is achieved, the arrangement length of the arm support is greatly increased, the tipping moment of the arm support can be effectively reduced, and the operation capacity of the arm support is enhanced.

Description

technical field [0001] The invention relates to the technical field of operating machines, in particular to an operating machine. Background technique [0002] Operating machinery is an important part of the equipment industry. It is mainly used for earth and stone construction, road maintenance, lifting and loading and unloading operations, etc. Therefore, operating machinery can be divided into lifting machinery, piling machinery, road machinery, compaction machinery, etc. according to the category. [0003] The turntable is an important part of the working machinery that needs to rotate. The upper part of the turntable is hinged to the end of the arm frame, the lower part of the turntable is fixed to the slewing support structure, and the slewing support structure is installed on the fixed turret. During the slewing operation, the turntable and the slewing support structure are driven by the driving mechanism to turn on the horizontal plane relative to the fixed turret, s...

AI Technical Summary

Problems solved by technology

[0006] The invention provides an operating machine, which is used to solve the problem that the eccentricity of the existing turntable is too small, and it is difficult to make full use of the free space above the cab of the operating machine, which results in the limitation of the length of the boom.
