Title:
INTELLIGENT HYDRAULIC SYSTEM AND HYDRAULIC JACKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/109049
Kind Code:
A1
Abstract:
Provided in the present application are an intelligent hydraulic system and a hydraulic jacking device. An oil path of the intelligent hydraulic system is provided with a first pressure measurement point for measuring an oil pressure of an oil output end of a hydraulic pump, a second pressure measurement point for measuring an oil pressure of an oil intake end of a balance valve, and a third pressure measurement point for measuring an oil pressure of an oil output end of a rod cavity of a jacking oil cylinder. The system further comprises a controller, which is configured to: respectively collect a first oil pressure value Ps of the first pressure measurement point, a second oil pressure value P2 of the second pressure measurement point, and a third oil pressure value P1 of the third pressure measurement point; calculate a first loop section pressure difference Ps1 between the first pressure measurement point and the third pressure measurement point, and a second loop section pressure difference Ps2 between the first pressure measurement point and the second pressure measurement point; and process the first oil pressure value Ps, the second oil pressure value P2, the third oil pressure value P1, the first loop section pressure difference Ps1 and the second loop section pressure difference Ps2, and perform feedback determination on a hydraulic element of the intelligent hydraulic system according to a processing result. The aim of intelligent determination is achieved, and manual errors are reduced.
