Abstract

The invention discloses a hydraulic excavator operating device with movement redundancy characteristics. The lower end of a movable arm is hinged with a frame; the upper end of the movable arm is hinged with one end of a bucket arm; the other end of the bucket arm is hinged with one part of a bucket; the other part of the bucket is hinged with one ends of a pair of bucket hydraulic cylinders; the other ends of the pair of bucket hydraulic cylinders are hinged with the upper ends of a pair of rockers; the lower ends of the pair of rockers are hinged with the frame; the middles of the pair of rockers are hinged with one ends of the pair of rocker hydraulic cylinders; the other ends of the pair of rocker hydraulic cylinders are hinged with the other part of the frame; one ends of a pair of movable arm hydraulic cylinders are hinged with the middle of the movable arm; the other ends of the pair of movable arm hydraulic cylinders are hinged with the frame; one ends of a pair of bucket arm hydraulic cylinders are hinged with the middle of the bucket arm; and the other ends of the pair of bucket arm hydraulic cylinders are hinged with the frame or the movable arm. The hydraulic excavator operating device is high in bearing capacity, high in rigidity and high in driving force arm, the load can be driven through low driving force, the energy consumption is reduced, and the hydraulic excavator operating device has the advantages of movement redundancy.

Description

technical field [0001] The invention relates to an excavator, in particular to a device for a front shovel hydraulic excavator. Background technique [0002] Large-scale front shovel hydraulic excavator is the main tool for mining in open-pit coal mines, and its excavating working device is the main component to complete various functions of the excavator. There are few domestic studies on the working device of hydraulic front shovel excavator. Chinese patent CN200520035287.8 involves a A horizontal pushing mechanism of a front shovel operation device of a hydraulic excavator, characterized by the hinged bucket hydraulic cylinder piston rod and the front end of the boom, the hinged rear part of the stick with the front end of the boom, the hinged bucket with the front end of the stick, and the hinged bucket with the bucket. The ends of the cylinder barrel of the hydraulic cylinder are hinged, and the hinge points form a four-bar mechanism with a quadrilateral structure in th...
