Purpose
The railway spacing ruler is used to measure the spacing of the standard gauge railway turnout curve.
, Features
Compared with the popular stand rulers on the market today, although the ruler body material is aluminum alloy, the engraved lines on the ruler body are not integrated with the ruler body, but The ruler made of special stainless steel is individually embedded in the ruler body. Since the linear expansion coefficient of the ruler is very close to the linear expansion coefficient of the cement sleepers on the railway line, it automatically eliminates the influence of the ambient temperature.
, Main data
Support distance measurement range~.
Branch distance indication error
The insulation resistance between the measuring head and the measuring head, and between the measuring head and the pressure measuring plate are tested continuously under voltage, and the insulation resistance is not less than.
, Structural Schematic
, Usage
When measuring the support distance, place the support distance insulating plate on the straight rail of the switch, so that the two round measuring heads are in contact with the working edge of the straight rail , move the cursor so that the pressure measuring plate is in contact with the guide curve, and the support distance indication value can be read through the cursor.
Method for calibrating the straightness of the base plane of the ruler
Pull the travel frame of the scale to the end (insulation sleeve end) with the engraved line facing down, and place the end of the scale on the scale calibrator Under the end test plate, the straightness of the datum plane can be verified at this time.
The support ruler must be subject to periodic calibration.
