Introduction

This procedure is based on TB/T 1924-2008 "Standard gauge rail gauge", TG/GW115-2012 "High speed Railway ballastless track repair rules (Trial) ", TG/GW116-2013" high-speed railway ballast track line dimension Repair rules (Trial) ", the JJG 219-2008" standard gauge rail gauge "to be revised. And JJG 219-2008, the main technical changes in addition to editorial changes are as follows.

--- increase the introduction;

--- delete the reference file;

--- "level (high)" unified as "high";

--- "the gap between the ruler and the direction of the marking" is changed to "the distance from the gauge to the scale" of the gauge;

- Change the "gap between the wheel and the pointer" to "between the upper end of the pointer and the surface of the wheel distance";

--- unified gauge distance gauge gauge error of the specified form, cancel the ruler line indication error requirements, while Adjust the "zero value" outside the measurement point of the error test method;

--- increase the track gauge foot tilt state of the ultra-high value change requirements;

--- added a new gauge gauge pedometer;

--- the relevant provisions of the wooden gauge are removed;

--- the elimination of long blisters and ultra-high plate gauge;

- the "measurement uncertainty assessment" of the original procedure was deleted.

3 Overview

Gauge gauge is used to measure the railway line gauge, ultra-high, check the interval and the distance from the back of the railway dedicated measuring device with The gauge range of the gauge is shown in Table 1. According to its accuracy is divided into 0, 1, 2 three levels, 0 gauge gauge Used to measure the allowable speed of not more than 350km/h of the railway lines, a gauge gauge for measuring the allowable speed does not exceed 250km/h of the railway lines, two gauge gauge for measuring the allowable speed of not more than 160km/h of the railway lines. rail from the scale structure is divided into scale and digital category, the schematic diagram shown in Figure 1 and Figure 2.
