Method.
Background technology
It is made currently, the movable gauge head pull rod of all railway gauge rules is all medium carbon steel, since movable gauge head pull rod is long
Spend short, linear expansion coefficient is smaller, because the line expansion that the temperature difference generates is also smaller, ignores, does not consider that its temperature difference generates
Line expand influence to gauge.
Currently, when railway gauge rule is examined and determine, with 20 DEG C for standard, is examined and determine in calibrating room room, determine gauge size.
Gauge is exactly the distance of two one steel rail of railway, belongs to linear measure longimetry.Two gauge heads of railway gauge rule are exactly for measuring gauge
Distance.Railway gauge rule is aluminum alloy materials, and effective length is 1140mm or so, and linear expansion coefficient is 23.8 × 10-6mm/
℃；The sleeper of railway track is cement material, their effective lengths are 1435mm, their linear expansion coefficients are 11.5 × 10-6mm/
℃.When railway gauge rule uses on outdoor railway, or when examining and determine room Indoor, when temperature deflects away from 20 DEG C, gauge
The gauge of ruler, just and the gauge of rail generates temperature deviation (abbreviation railway gauge rule gauge temperature deviation, be set as △), influences standard
True property, (sleeper of railway track is cement material, and railway gauge rule comparator is mild steel material, and linear expansion coefficient is close
Cement material, because the two linear expansion coefficient is close, so the line expansion length approximately equal that its temperature deviation generates)

It is that can ignore processing to spend deviation, Dui Yu≤160km/h motor-cars rail tracks and high ferro rail track, it is desirable that railway used
Gauging rule must carry out its gauge temperature deviation automatic compensation disposition.
At present on ,≤160km/h railways, the 1 grade of railway gauge rule and 0 grade of railway gauge rule used, gauge measures all
It is that electronic digit is shown, the compensation device of gauge temperature deviation is carried out automatically by specially designed chip processor
Compensation deals.Digital display class railway gauge rule cost is especially expensive, and performance is also unstable, and failure is more.So special demands one in the market
The gauge temperature compensation means of kind simple cheap railway gauge rule.
National relevant regulations, the railway of Dui Yu≤160km/h are to ignore processing to its gauge temperature deviation, used 2
Grade railway gauge rule, is essentially all to be measured to gauge using scale class device, and simple cheap is practical.
Scale class railway gauge rule, the groove for measuring the scale device of gauge are fixed, and performance is stablized, simple real
With, but because cannot carry out on gauge temperature deviation compensation deals , ≤160km/h railways, cannot use at present.
