Description
Technical field
The present invention relates to rail detection field more particularly to a kind of steel rail abrasion detection devices.
Background technique
Rail is the building block of railroad track, and the wheel for being mainly used for pilot engine vehicle advances, and is born on wheel
Pressure, and transmit that force on sleeper.With the fast development of railway, heavy haul train and bullet train are in railway transportation
Status it is more and more important, and the presence of heavy haul train and bullet train is worn rail, deformation increase, when on route
The rail used has reached severely injured degree, just will affect traffic safety.
Rail during use, can generate rail wear.Rail wear is primarily referred to as rail on sharp radius curve
Side wear and undulatory wear.It is normally, with increase axis weight and pass through gross weight under normal circumstances as vertical abrasion
Increase.Wherein: side wear occur on the foreign stock rail of sharp radius curve, be hurt on present curve main Types it
One.For train when running on curve, the friction and sliding of wheel track are to cause the basic reason of side wear.Train passes through minor radius
When curve, it will usually the case where Wheel/Rail Two-Point Contact occur, the side grinding at this moment occurred is maximum；Waveform abrasion refer to rail surface
The conquassation of the wavy irregular wear of upper appearance, substantially waveform.Wave mill can cause very high dynamic action between wheel and rail, accelerate
The damage of rolling stock and track component increases maintenance cost；Furthermore the high vibration of train can make passenger uncomfortable, sternly
Traffic safety can be also threatened when weight；Wave mill is also the source of noise.On some shipping main lines in China, there is serious wave
Mill.Its development speed is also faster than side grinding, becomes the main reason for switching tracks.
Wave mill mainly appears on heavy haul transport line, especially especially severe on transporting coal fortune mine line, on High-Speed Passenger transport line
Also there is different degrees of generation.It is main that ripple abrasion occur on the higher railway of train speed, and mainly appear on straight line and system
