Walking control system and method and mechanical device

Abstract

The invention provides a walking control system and method and a mechanical device. The walking control system comprises control handles and a controller. The holding portion of each control handle isprovided with a rolling wheel. The rolling wheel is provided with a rolling potentiometer in a matched manner, wherein the rolling potentiometers are electrically connected with the controller. The controller is used for obtaining signals of the potentiometers and controlling an electrical control valve of a hydraulic system to act according to the signals, and then a walking mechanism of equipment is controlled to act. Thumb rolling wheels are arranged on the control handles to replace a walking stepping mechanism so as to control the mechanical device to walk, and the thumb rolling wheels are used for operating the walking mechanism of the equipment. Control over actions of the whole vehicle, such as the walking mechanism and an operation arm, is achieved through the two control handles, so that the space of a drive cab is expanded, and cost is lowered.

Description

technical field [0001] The present disclosure relates to the field of mechanical equipment, in particular to a walking control system, method and mechanical equipment. 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 increasing demand for engineering construction and facility construction, the operational performance requirements for mechanical equipment, especially construction machinery such as excavators, are also getting higher and higher; existing parts of large crawler construction machinery such as excavators Manipulate mechanical structures such as figure 1 As shown, it includes the left and right walking pedals. By pushing forward or pulling the pedals back, the crawler on the corresponding side can be controlled to advance or retreat, so as to realize the overall forward, backward, left turn, right turn and other actio...

AI Technical Summary

Problems solved by technology

[0004] The inventors have found that currently the operation methods of large crawler-type construction machinery such as excavators mostly use both hands and feet. The driver's feet control the pedals to control the overall movement of the construction machinery, and the hands control the joystick to control the construction machinery. However, when the operation arm moves while moving, the driver's hands and feet need to move at the same time, and the hands and feet are in a tense state for a long time, which is easy to cause operation errors due to uncoordinated movements; in addition, the left and right walking pedals are located on the body In front of the oblique front, the feet need to be kept above the pedals at all times, which will block the driver's vision of the low places for a long time, which is not conducive to the driver's operation
