Abstract

The invention provides a static railway track assembly overall dimension and damage optical detection system which comprises linear hard light sources, annular hard light sources, high-speed cameras for optical detection, an image processing card, a computer, data and power source cables, walking type machine frameworks and mileage sensors installed on wheels of the walking type machine frameworks. A track assembly comprises steel rails, steel rail fastener combinations, sleepers, sleeper plates and railway ballasts. Each high-speed camera for optical detection and the corresponding linear hard light source which are installed on the corresponding walking type machine framework and located on the same side of the same corresponding steel rail and are higher than the rail surface form a steel rail and steel rail fastener combination contour section dimension optical detecting set. By means of the technology, the functions of detecting the steel rail overall dimension, the steel rail top face corrugated abrasion and rail bottom slopes and the functions of detecting steel rail fastener gland nut loosening, failures and missing are achieved.

Description

technical field

[0001] The present invention relates to a kind of optical detection system for outline size and disease of static railway track components, more precisely, it is an optical system for comprehensively detecting the state of railway track components in a static state where the applied load cannot deform them. Detection Systems. As opposed to static railway inspections, dynamic inspections such as passenger and freight trains, rail cars, and track inspection vehicles are loaded on the railway tracks, which are sufficient to deform railway track components. Background technique

[0002] On the running railway, whether it is due to the wheel idling caused by the emergency acceleration of the running train, or the wheel lock caused by the emergency braking deceleration, which aggravates the wavy wear and block on the top surface of the rail, or the rail head caused by normal operation The abnormal wear or broken rail of the rail head caused by wavy wear, fat edge ...
