Abstract

The invention discloses a redundant oil way and a combined oil way used for connecting an electro-hydraulic switching machine oil way and belongs to the field of switching machine oil ways. The electro-hydraulic switching machine oil way comprises an oil pump, an oil cylinder, an oil outlet pipe connected between an oil outlet of the oil pump and the oil cylinder, and an oil return pipe connectedbetween an oil return hole of the oil pump and the oil cylinder; the redundant oil way is used for communicating at least two electro-hydraulic switching machine oil ways; the redundant oil way communicating the two electro-hydraulic switching machine oil ways comprises four hydraulic check valves and two rubber pipes, the two hydraulic-control check values are installed on oil outlet pipes of thetwo electro-hydraulic switching machine oil ways and the two oil outlet pipes communicate by one rubber pipe; the other two hydraulic-control check valves are installed on the oil return pipes of thetwo electro-hydraulic switching machine oil ways respectively and the two oil return pipes communicate by another rubber pipe; and the hydraulic-control check valves are closed when the oil pump of the corresponding electro-hydraulic switching machine cannot provide high-pressure oil. The oil ways provided by the invention can enhance reliability in multi-traction point turnout switching.

Description

Technical field [0001] The invention relates to the field of switch machine oil circuits, in particular to the field of switch machine oil circuits for railway turnouts, in particular to a redundant oil circuit and a combined oil circuit for connecting the oil circuits of an electro-hydraulic switch machine. Background technique [0002] At present, the configuration combination of electro-hydraulic switch machines for multi-traction point switches is generally in the form of full main engine and main and auxiliary machines (the electro-hydraulic switch machine with power source is the main machine, and the electro-hydraulic switch machine without power source is the auxiliary machine. ), the main and auxiliary machines are divided into one main machine plus one auxiliary machine, and each main machine plus two auxiliary machines. [0003] With the development of high-speed railways in our country, the requirements for the reliability of turnout switching systems are getting higher...
