AI Technical Summary

Problems solved by technology

Because the turnout switch works in the harsh outdoor environment, the existing switch often has the following problems during the working process: 1. The surface of the dynamic and static contacts is severely corroded, and various oxides and splashes cause the static and dynamic contacts to phase Adhesion and poor contact will cause accidents; 2. Moisture condensation in the air will also cause contact adhesion; 3. The strong vibration generated when the train passes may cause the contact to malfunction, reducing the reliability of its use

Abstract

The present invention is one change-over switch for track switch machine in railway switch transition controlling system. The change-over switch includes one front static contact and one back static contact separately located in front and back of one protecting casing, one movable contact arm with movable contacts in two ends set between the front static contact and the back static contact, one rotation shaft in the middle part of the movable contact arm, one converting arm set in the middle part of the movable contact arm, one elastic connector with one end connected to the converting arm, one driving crank with one end connected to the elastic connector and the middle part mounted through one rotation shaft onto the fixing rack, and one driving mechanism connected to the other end of the crank. The present invention has reasonable structure and high reliability.

Description

technical field [0001] The invention relates to a switch for a switch for a switch of a railway switch. Background technique [0002] The railway switch switch machine is a device used to switch the railway switch, and its switching process is realized by the switch in the control circuit. Because the turnout switch works in the harsh outdoor environment, the existing switch often has the following problems during the working process: 1. The surface of the dynamic and static contacts is severely corroded, and various oxides and splashes cause the static and dynamic contacts to phase Adhesion and poor contact can lead to accidents; 2. Moisture condensation in the air can also cause contact adhesion; 3. The strong vibration generated when the train passes may cause the contact to malfunction, reducing the reliability of its use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a switch for a switch machine with hig...
