油圧仕事占有装置
Document Type and Number:
Japanese Patent JP6831850
Kind Code:
B2
Abstract:
A hydraulic working occupation apparatus includes: a hydraulic forming mechanism; an output element; a ball elbow mechanism connected to the hydraulic forming mechanism; and an occupation piston sleeve (25) connected to the ball elbow mechanism, wherein when a high pressure liquid is input, the high pressure liquid acts on the output element, so that the output element moves towards outside of the liquid, thereby outputting work done by liquid pressure; the ball elbow mechanism generating the location deformation drives the occupation piston sleeve (25) to move, so that the occupation piston sleeve (25) and a liquid therein make up for a liquid space left by the output element after the output element moves outwards, and when the output element moves back into the liquid, the ball elbow mechanism and the occupation piston sleeve (25) return to original locations. By using the occupation apparatus, when a working piston works towards outside of a liquid under the effect of hydraulic pressure, an occupation piston sleeve (25) and a liquid therein can occupy a liquid-off space of the piston in time, to ensure that the high liquid level does not rise and fall or the pressure of the high hydraulic pressure does not change, thereby avoiding unstable working and wastes of high pressure liquids.
