Excavator control handle, walking system and excavator

Abstract

The invention provides an excavator control handle, a walking system and an excavator. The excavator control handle comprises a handle main body and an electric signal circuit, the handle main body isprovided with rolling knobs, and the rolling knobs are electrically connected with the electric signal circuit; the rolling knobs roll to different positions to connect different circuit parts in theelectric signal circuit so as to output different electric signals, a whole machine controller receives the electric signals output by the rolling knobs of a left handle and a right handle and controls opening of corresponding oil supply loops of hydraulic units and hydraulic oil flow, and walking control is achieved. According to the excavator control handle, the walking system and the excavator, electric control signals are adopted to replace a pilot valve, corresponding walking can be continuously controlled after one-time rolling knob rotation is conducted, no constant operation is needed, the operation comfort is improved, and meanwhile the problem that an excavator walking system in the prior art is large in energy consumption is solved.

Description

technical field [0001] The present disclosure relates to the technical field related to excavators, and in particular, relates to an excavator joystick, a walking system and an excavator. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] With the development of intelligent information products becoming more and more mature, they can also meet the product use in terms of technology and quality. In addition, people have higher and higher requirements for the comfort of excavator operation, and at the same time, they are more pursuing low energy consumption. Increasingly demanding. [0004] The inventor found that the existing excavator walks through the hands or feet to operate the walking joystick all the time, and the walking operation device generally adopts two kinds of manipulation methods, the joystick and the pedal, which are connect...

AI Technical Summary

Problems solved by technology

The walking is controlled by the walking joystick through hydraulic control. At the same time, during the moving process, the two joysticks are always pulled or the pedals are stepped on, which consumes a lot of energy. and has higher energy consumption
