Abstract

The invention discloses a control method and system for speed matching of an excavator under different working conditions. The method comprises the following steps that a control signal sent by a pilot handle through user operation is received, and the control signal comprises an opening signal and a switching signal of the pilot handle; the control signal is sent to an electronic monitor; and an instruction sent by the electronic monitor is received, and a proportional electromagnetic valve group is controlled to operate a machine tool. The control system comprises a pilot handle opening degree sensor, a controller, the proportional electromagnetic valve group, the electronic monitor and the pilot handle with a constant speed switch and a flow switch. The problem that in the prior art, a pilot handle is manually shifted to a needed angle and is manually and continuously kept is solved.

Description

technical field

[0001] The invention relates to a control method and system for speed matching of different working conditions of an excavator, belonging to the technical field of excavator engineering. Background technique

[0002] As a commonly used construction machine, excavators are widely used in urban construction, earthwork construction, farmland water conservancy construction and other occasions. When using an excavator for continuous operations such as crushing, the driver needs to continue to toggle the implement switch, which is prone to operational fatigue, and the implement switch is mostly located on the pilot handle. Operating the switch for a long time is easy to misoperate the pilot handle. Due to human factors, The angle of the toggle switch is uncontrollable, resulting in uncontrollable speed matching of the machine tool under different working conditions. Contents of the invention

[0003] In order to solve the deficiencies of the prior art, the objec...
