Winch control method and device for working machine, medium, and working machine

Abstract

The embodiment of the invention provides a winch control method and device of a working machine, a medium and the operation machine. The method comprises the following steps that: when it is determined that the working machine is in a rope winding state, a first included angle between a telescopic arm of the working machine and a horizontal plane at the current moment, and a second included angle between the telescopic arm of the working machine and the horizontal plane at the previous moment are obtained; according to the first included angle and the second included angle, the change speed of the included angle during operation of the telescopic arm within preset time is determined; according to the change speed of the included angle, the target motor rotating speed of a winch is determined; and the winch is controlled to operate at the target motor rotating speed so as to perform rope winding operation. The invention aims to overcome the defects of long consumed time and low efficiency due to the fact that rope winding operation is conducted by manually observing the falling amplitude of a telescopic arm in the prior art.

Description

technical field [0001] The invention relates to the technical field of operating machine control, in particular to a control method, device, medium and operating machine for a hoist of an operating machine. Background technique [0002] With the rapid development of my country's infrastructure, cranes have become indispensable hoisting equipment in factories and work projects, which has greatly promoted the progress of society. After the crane completes the lifting task, the car is collected. The process of receiving the car is to fully shrink the telescopic arm first, and then slowly place the telescopic arm on the telescopic arm support. [0003] When the telescopic arm is placed on the telescopic arm support, as the angle of the telescopic arm decreases, the wire rope will also be shortened thereupon. In the prior art, the rope-retracting operation of the steel wire rope is manually controlled by observing the drop range of the telescopic arm by the operator. The entire ...
