Problems solved by technology

Pneumatic turnout control devices are limited by the working environment. If the pneumatic turnout cannot be used without an air source supply; in an environment where the pneumatic turnout device is used with an air source, it is easy to cause unstable air pressure, insufficient thrust, and long air supply lines. The trachea is easy to leak air, and the maintenance workload is heavy; the electric push rod turnout control device includes a rotating motor and a reduction box. This device has the disadvantages of complex structure, large volume, high failure rate, slow speed, inconvenient installation in small and medium roadways, and complicated maintenance.

Abstract

The invention relates to an electric linear points switch machine, belonging to the field of railway points control devices. The electric linear points switch machine comprises a control device, an actuator, a display, an approach switch and a controller, wherein the actuator is connected with a points bar; an iron track near the points bar is connected with the approach switch; the output end of the control device is respectively connected with the actuator and the display; and the controller is connected with the input end of the control device. The invention controls a silicon-controlled switch and the working state of the actuator by a PLC (programmable logic controller), automatically controls the points by controlling the points bar through the actuator, realizes the switch control by adopting controllable silicon, initiates the possibility of the work of the controllable silicon under high voltage and heavy current and realizes the operation of using the controllable silicon to switch a motor; ands in addition, the electric linear points switch machine has novel structure, small volume and easy and convenient installation, can work under the 660 V voltage or 1140 V voltage of a three-phase alternating-current supply and push points in short time and is safe and reliable.

Description

technical field [0001] The invention relates to a railway turnout control device, in particular to an electric linear turnout switch machine. Background technique [0002] At present, when transporting materials and personnel on a large scale, railways are generally used for transportation, especially in mines, the transportation of minerals, materials and personnel in coal mines above and below mines is mainly carried by railways, and the operation of locomotives on railways needs to be changed. For the direction, the pneumatic switch control device or the electric push rod switch control device are generally used to automatically change the switch to change the running direction of the locomotive. Pneumatic turnout control devices are limited by the working environment. If the pneumatic turnout cannot be used without an air source supply; in an environment where the pneumatic turnout device is used with an air source, it is easy to cause unstable air pressure, insufficient...
