Embodiment 1

[0021] In the technical solutions disclosed in one or more embodiments, such as figure 1 As shown, an excavator control handle includes a handle body and an electric signal circuit. The handle body is provided with a scroll knob, and the scroll knob is electrically connected to the electric signal circuit, and the electric signal is turned on by rolling the knob to a different position. Different circuit parts in the circuit output different electrical signals, and the electrical signals can be used to control the walking of the excavator.

[0022] Realizable, the electrical signal circuit can be set to different on-positions, the scroll knob can be turned on to different on-positions in the circuit, and different electrical signals can be obtained.

[0023] In some embodiments, the electrical signal circuit can be as figure 2 As shown, it includes an input circuit and an output circuit, the output circuit has a plurality of branch circuits, and the input circuit is connecte...

Embodiment 2

[0029] This embodiment provides a walking control system of an excavator, such as image 3 and 4 As shown, it includes a left handle, a right handle, a complete machine controller and a hydraulic control unit. The left handle and the right handle adopt an excavator joystick in Embodiment 1, and the complete machine controller receives the scroll knobs of the left handle and the right handle. The output electrical signal controls the opening of the corresponding oil supply circuit of the hydraulic unit and the flow of hydraulic oil, thereby realizing the travel control of the excavator.

[0030] In this embodiment, the electronic control signal is used instead of the pilot valve, and the corresponding walking can be continuously controlled after one rotation of the rolling knob without continuous operation, which improves the comfort of operation, and at the same time solves the problem of high energy consumption of the existing excavator walking system The problem.

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...
