　　The gauge gauge is used to measure the inner gauge of two steel rails. The Chinese standard gauge is 1435mm, with an error of -2 and+5mm. For straight lines, the two rails should be level, and the horizontal bubble on the gauge gauge should be centered; The outer track of the curve is higher than the inner track, and different elevations are calculated based on different radii; That is to say, if the height difference between the inner and outer rails exceeds the allowable range, maintenance must be carried out.

　　1、 Introduction to track gauge:

　　The gauge ruler is a narrow gauge track detection device, which consists of a ruler body, a scale ruler, and a frame on the ruler body. The ruler body is a duplex shaped profile structure with a square tube shape. The outer edges of the upper and lower sides of the profile have outward extensions, and a groove is opened on the inner side of the outer edge. The stainless steel scale ruler is inserted into the groove and fixed at its end with a pin. The ruler body is equipped with a frame in the middle, and there are auxiliary rulers, side plates, and adjustment bolts fixed on the frame. The end of the ruler body is equipped with a cross plate and a measuring head. The entire gauge ruler has a T-shaped structure.

　　2、 Main technical features:

　　1. Significantly improve the accuracy of horizontal and super-high measurements to meet the super-high measurement requirements of high-speed lines;

　　2. Automatically eliminate additional errors in gauge measurement caused by environmental temperature, and improve the accuracy of gauge measurement;

　　3. It can achieve hardware free replacement or maintenance of the gauge probe under normal wear and tear, improving the efficiency and service life of the gauge ruler

　　3、 Daily maintenance and upkeep of track gauge:

　　In addition to normal maintenance, the following four points should be particularly noted for the gauge gauge calibrator:

　　(1) After completing the calibration work of the gauge gauge calibrator with a dial gauge, the movable probe of the calibrator should be adjusted to the appropriate position, and the dial gauge probe should be fully released, so that the spring of the dial gauge is completely in a non stressed state.

　　(2) After completing the verification work, the work gauge should be hung vertically for storage. If the gauge is placed flat, consideration should be given to self weight deformation and a reasonable support position should be selected.

　　(3) For calibrators using digital rulers, when disassembling the digital ruler for inspection, the digital meter and ruler should not be separated, but should be disassembled as a whole to avoid losing the limit piece. In short, metrological personnel should strictly follow the verification regulations, conscientiously follow the operating procedures, standardize the filling of verification records, and correctly present verification certificates during the verification process, in order to ensure the accuracy and reliability of value transmission.

　　(4) Selection of support position. The gauge belongs to a slender rod, and its actual length value (1435 ± 0.20) mm is used. Therefore, in the selection of the support position, Bessel point support should be used, that is, the support position a=0.2203L. In the formula, a is the support position, mm; L is the gauge length, mm.
