Embodiment Construction

[0051] The switch machine is the key equipment for the conversion of railway turnouts, and is used for the conversion, locking and display of various railway turnouts. The electro-hydraulic switch machine adopts hydraulic transmission, including a hydraulic power unit and a conversion unit. The function of the conversion unit is to convert, lock and indicate the state of the switch. The conversion unit is divided into squeezeable and non-squeezable types. The non-squeezable conversion unit is generally used The first traction point of the point rail (core rail) of the traction switch, the squeezable conversion unit is generally used for single-point traction switch or multi-point traction switch except the first traction point of the point rail (core rail).

[0052] The non-squeezable conversion unit mainly includes a conversion locking mechanism, a locking display mechanism, and a mechanical manual mechanism; the conversion locking mechanism is mainly composed of an oil cylind...

Abstract

The invention discloses an electric-hydraulic switch machine which comprises a hydraulic power unit and multiple switch units. Each switch unit comprises a switch locking mechanism which comprises an oil cylinder, the oil cylinders of the switch units are serially connected and are equal in volume, and the hydraulic power unit drives the oil cylinders to act synchronously. Through a designing mode that the oil cylinders of the switch units are serially connected and equal in volume, synchronous switching of multiple rail junction traction points is realized, and the electric-hydraulic switch machine is quick in switching, high in synchronicity, suitable for switching, locking and indicating of various rail junctions and especially suitable for high-speed rail junctions.

Description

technical field [0001] The invention relates to the technical field of railways, in particular to an electrohydraulic switch machine. Background technique [0002] With the development of railway transportation in the direction of heavy load and high speed, the reliability requirements for switch machines are getting higher and higher. The existing domestic turnout switching equipment mainly includes electric and electro-hydraulic switch machines. Among them, the electric switch machine mainly has unstable switching force output, difficult adjustment, large mechanical wear, many control materials, investment and energy consumption. However, the existing electro-hydraulic switch machines have problems such as poor conversion synchronization when the main and auxiliary machines are used for traction. [0003] Therefore, creating a new electro-hydraulic switch machine with good conversion synchronization, which is suitable for domestic high-density, heavy-duty, and high-speed ...
