Abstract

The invention belongs to the technical field of excavator equipment, and relates to an excavator being large in excavation range and high in stability. The excavator comprises a lower traveling mechanism, an excavator body, a working device and a counterweight, wherein the lower traveling mechanism and the excavator body are connected through a rotating support; a first hydraulic oil cylinder group is arranged between the working device and excavator body; cylinder tubes I in the first hydraulic oil cylinder group are hinged with the excavator body; the tops of piston rods I are fixedly connected with the working device; the counterweight is arranged at the rear part of the excavator body; a second hydraulic oil cylinder group is arranged between the counterweight and the excavator body; cylinder tubes II in the second hydraulic oil cylinder group are fixedly connected with the excavator body; and the tops of piston rods II are fixedly connected with the front part of the counterweight. Not only can the excavation range of the excavator be enlarged, but also the overall stability of the excavator can be prevented from being influenced; the relatively convenience operation can be provided for the excavation of rugged mountain roads and the ground with very poor road conditions; and the gravity center of the counterweight deflects backward, so that the material cost of the counterweight can be reduced.

Description

technical field [0001] The invention belongs to the technical field of excavator equipment, and relates to an excavator with a large digging range and good stability. Background technique [0002] The excavator includes the lower walking mechanism, the fuselage and the working device. The fuselage includes the cab, the power unit, the transmission system and the counterweight, etc. The working device includes the boom, stick and bucket and their corresponding control hydraulic cylinders. The fuselage and the base of the working device are fixed and rigidly connected, and the counterweight is fixed in the rear shell of the fuselage. The overall working device and the counterweight do not have the ability to move. The excavation range of the excavator is limited, and the excavation operation is not easy to operate in areas with uneven and rugged mountainous areas, and the working conditions are complicated. If the excavation range is too large and climbing on a steep slope, it...
