HYDRAULIC ENGINEERING MACHINERY MANIPULATOR
Document Type and Number:
WIPO Patent Application WO/2023/173976
Kind Code:
A1
Abstract:
The present invention provides a hydraulic engineering machinery manipulator, comprising a system controller and a manipulation skeleton. A plurality of sensors are provided on the manipulation skeleton to respectively correspond to different cylinders of a hydraulic engineering machine; rotary potentiometers are provided on the manipulation skeleton to correspond to rotary joints of the hydraulic engineering machine; human arms wear the manipulation skeleton, and the plurality of sensors are driven by means of movements of the human arms; the system controller controls, according to positions of the sensors, the oil inlet amount of each corresponding cylinder in real time, and controls the plurality of cylinders of the hydraulic engineering machine to act at the same time; a flow sensor is provided between an oil inlet pipe or an oil outlet pipe of each cylinder of the hydraulic engineering machine and an electromagnetic valve to perform position feedback of the cylinder to control accurate movement of each cylinder. The present invention is simple, convenient, and flexible to operate and quick to learn; for some simple engineering machinery, a disabled person having only one hand can also operate, and for a hydraulic engineering machine having many joints or a hydraulic engineering machine needing double-mechanical-arm cooperation, an able-bodied normal person can freely operate.
