Title:
DOUBLE-WINCH HYDRAULIC CONTROL SYSTEM, OPERATION MACHINERY, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/130624
Kind Code:
A1
Abstract:
A double-winch hydraulic control system, comprising: a first force measurement member (101), which is used for measuring a first force value of a first steel wire rope (103); a second force measurement member (102), which is used for measuring a second force value of a second steel wire rope (104); a first motor (200), which is connected to the first steel wire rope (103); and a second motor (300), which is connected to the second steel wire rope (104), wherein on the basis of the comparison between the first force value and the second force value, the first motor (200) is controlled to tension the first steel wire rope (103), or the second motor (300) is controlled to tension the second steel wire rope (104). Further comprised are operation machinery and a control method. By tensioning the first steel wire rope (103) or the second steel wire rope (104), the deflection of a working apparatus is automatically adjusted, thereby improving the working efficiency.
