AUTOMATIC RAILWAY RECORDING CONTROL SYSTEM USING COMPRESSED AIR

Abstract

The useful solution refers to an automatic pneumatic railway track switch control system. The equipment includes a remote control, control cabinet, pneumatic solenoid valves, pneumatic actuator assembly, travel sensors, and a status and direction display unit. The control cabinet receives commands from the remote control and controls the solenoid valves to supply, release, or reverse compressed air to the pneumatic cylinder. The pneumatic cylinder moves the railway track switch via a power transmission mechanism. The travel sensors confirm the end-travel position of the pneumatic actuator assembly, and the status and direction display unit only displays the corresponding direction when a confirmation signal is received from the travel sensors. The equipment also includes a warning unit, a spark-safe power supply circuit, and a battery charger along with a backup battery to enhance safety and operational reliability in underground mines, underground structures, or areas requiring explosion safety, or on internal railway lines.
