Problems solved by technology

When measuring by eddy current method, there is no limit to the driving speed, but only tread wear can be detected
[0005] 3) Ultrasonic telemetry method: When the vehicle speed is ≤5km/h, the telemetry sensor group can measure the distance from each characteristic surface of the wheel, and after analysis and processing, parameters such as wheel diameter, rim thickness, tread wear and vertical wear can be obtained, but Unable to get the complete shape curve of the wheel
However, the existing measuring device is used to illuminate from directly below the track and shoot directly below. It is necessary to use a special track (steel plate) whose width is about 2/5 of the width of the wheel tread, and 3/5 of the wheel tread is exposed for s...

Abstract

An in-line dynamic detecting apparatus for the profile size of wheel pair on rolling stock is composed of the camera units installed at inside and outside of each rail, wheel detector close to the camera unit at inside of rail, proximity sensor before camera unit, go-off sensor behind camera unit, and data processing and control unit.

Description

Technical field [0001] The invention relates to an automatic detection device for a wheel set of a locomotive, in particular to an on-line dynamic automatic detection device for the outline and key dimensions of a wheel set of a locomotive based on image measurement technology. Background technique [0002] The wheel set is a key component of the locomotive running system, and the key dimensions of the wheel set are directly related to the driving safety. The rapid development of railway speed and the high-density operation of rolling stock have accelerated the wear rate of wheel sets. Therefore, in order to avoid the situation that the wheels whose external dimensions exceed the limit are still put into use and ensure the safety of the train running, it is necessary to dynamically detect the external dimensions of the wheelset. At present, the main technologies used at home and abroad for the overall dimensions of vehicle wheelsets are: [0003] 1) Contact measurement met...
