Electric excavator with cable winding device

Abstract

The invention discloses an electric excavator with a cable winding device. The electric excavator comprises an upper vehicle frame, a lower vehicle frame, an operation mechanism, an executing system and a dynamical system, wherein the upper vehicle fame is connected to the upper part of the lower vehicle frame in a rotating manner; the operation mechanism is mounted on the upper vehicle frame; the executing system is mounted in front of the upper vehicle frame; the dynamical system comprises an electricity supplying system and a hydraulic system; the electricity supplying system comprises a cable winding device, a front bracket, a rear bracket and a via-hole electricity collecting ring; one side of the front bracket is fixedly connected to the rear part of the lower vehicle frame; the other side of the front bracket is hinged to the rear bracket; the cable winding device is mounted on the rear bracket; an electricity supplying cable mounted on the cable winding device is connected with the via-hole electricity collecting ring. The electric excavator disclosed by the invention has the benefits that: the working noise is small; no tail gas is emitted; the cable winding device can wind or unwind the cable with a certain degree of tension along with the movement of the excavator, and can be adapted to turn within a certain angle. The electric excavator can also be used for practical operation of practical field trainings.

Description

technical field

[0001] The invention relates to the field of engineering machinery, in particular to an electric excavator with a cable take-up device. Background technique

[0002] In foundation excavation, mine excavation, and narrow space excavation operations in the field of demolition construction, small and medium-sized excavators, with their unique advantages of small size, flexibility, multi-function, and high efficiency, are increasingly becoming ideal equipment for earthwork applications, and user needs continue to expand. , while traditional fuel-fueled models often have hidden dangers such as fuel emission pollution and harmful gas poisoning during excavation operations in limited working spaces. For the existing electric excavators, the whole machine generally includes an upper frame, a lower frame, an execution system, an operating mechanism, and a power system, wherein the upper frame is connected by rotating parts such as the center of rotation of the frame a...
