Abstract

PURPOSE:To accurately measure the unevenness state of a rail by measuring the peak values from a reference line at the intermediate position and both end positions of chord lengthy every time the chord lens moves by a unit distance, and processing those measured values. CONSTITUTION:A couple of pedestals 3 are arranged at an interval in the lengthwise direction of the rail head peak surface 2 and rail catches 4 and 5 are provided to those pedestals 3. Reference based 6 and 7 are provided to the pedestals 3, level adjusting mechanism 8 and 9 are coupled with those reference bases 6 and 7, and a slide plate 18 is extended between the reference bases 6 and 7. The slide plate 18 is provided with a measuring element holder 20 slidably and a horizontal measuring element 21 is supported by this measuring element holder 20. Specific wavelength is set in the lengthwise direction of the rail head peak surface 2 and the peak value of each wavelength is measured by the vertical measuring element 21 at the intermediate position and both end positions. Those measured values are processed to measure the roughness of the rail head peak surface 2.
