Description

  The present invention relates to a guard flange width measuring device.

  In order to prevent derailment at the turnout and entry into different rails, measurements such as the flange width and the dimensions between the main rail and the guard rail are regularly performed. As shown in FIG. 1, this measurement is performed by measuring the flange way width W <b> 1 that is the distance between the nose rail 1 and the wing rail 2, the distance between the tongue rail 3 and the stock rail 4, and the distance W <b> 2 between the main rail 5 and the guard rail 6. (Refer to the circles in FIG. 1). When these intervals are out of the predetermined range, there is a risk of damage or derailment of rails or wheels, entry into different rails, etc., and repairs are necessary.

  Conventionally, a measuring ruler such as a general caliper has been used to measure the flange way width W1 of the branching device and the dimension of the interval W2 between the main rail 5 and the guard rail 6. Further, as a means for measuring the flange width W1, a point tip safety degree determination ruler having a vertical scale that can be slid vertically and horizontally with respect to a ruler body has been proposed (see, for example, Patent Document 1).

Japanese Utility Model Publication No. 7-44976

  However, with a general measuring ruler such as a caliper, as shown in FIGS. 1B and 1C, it is difficult to measure a flange width or the like where there is a drop between the rails or the rail shape is different. There was a problem. In addition, since the measurement position is judged by eye measurement, or the measurement direction with respect to the rail is shifted by the measurer, there is a problem that the measurement value varies depending on the measurer and the measurement error increases. The ruler described in Patent Document 1 has a problem that it is difficult to carry because the ruler itself is large, and the measuring procedure of the flange way width is complicated and time-consuming.

  The present invention has been made by paying attention to such a problem, and is a guard that is easy to carry, can suppress a variation in measured values, and can easily and efficiently measure the flange width, etc. with high accuracy.・ The purpose is to provide a flange width measuring instrument.

In order to achieve the above object, a guard flange width measuring instrument according to the present invention is a guard flange width measuring instrument for measuring a flange way width of a branching device and a dimension between a main rail and a guard rail.
