Title:
AUTOMATED TRACK INSPECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/007393
Kind Code:
A3
Abstract:
An autonomous device for rail track inspection includes a drive wheel system propelling the device via a drive wheel system, an automatic track loading fixture for and applying a load on rails, and sensors for taking track gauge measurement. Different automatic track loading fixtures may require stopping for load and measurement, or loading and measuring while still in motion. A switch agnostic system for operation with devices on a conventional railroad track system includes a linear slider movably mounted along a linear sliding support; multiple sensors mounted to the linear slider, the sensors operable to identify a rail of a track junction; and multiple roller bearings operable to engage the rail of the track junction and control the device across the track junction in response to movement of the linear slider along the linear sliding support.
