Six-cavity dual-medium pressure conversion hydraulic system

Abstract

The invention provides a six-cavity dual-medium pressure conversion hydraulic system, belongs to the technical field of pressure conversion of positioning machines and aims at providing a six-cavity dual-medium pressure conversion hydraulic system which is simple in structure, reliable in operation and low in use cost. The technical scheme adopted by the invention is as follows: pistons of three oil cylinders are connected together by virtue of a piston rod, so that a linkage purpose is achieved; a first hydraulic oil cylinder is communicated with an emulsion pump station by virtue of an emulsion three-position four-way reversing valve; a second hydraulic oil cylinder is communicated with a working oil port K of a hydraulic distributor by virtue of an oil-way pipeline; a third hydraulic oil cylinder is communicated with a working oil port J of the hydraulic distributor by virtue of an oil-way pipeline; the working oil ports H and J of the distributor are used for controlling the rotation direction of a motor according to different oil feeding directions. The six-cavity dual-medium pressure conversion hydraulic system provided by the invention is mainly used for a hydraulic system of the positioning machine.

Description

technical field [0001] The invention discloses a six-cavity double-medium pressure conversion hydraulic system, which belongs to the technical field of pressure conversion of positioning machines. Background technique [0002] The positioning machine is proposed to solve the problem of complete institutionalization of the installation and positioning of the underground hydraulic support. For a long time, the installation and positioning have been in a backward manual operation state, with strong labor, low work efficiency and many safety hazards. Change this The noise in this state is very high, and all levels and departments are actively developing, but so far there is still no competent machine. The hydraulic system on the existing positioning machine is completely used for oil pressure. Not only the structure is complex and huge, but also the operating cost High, it cannot be deployed in a small space, so it is imminent to study a hydraulic system of the positioning machi...
