As shown in FIG. 7, in order to diverge a vehicle running on a predetermined rail to another lane,
The tongue rails are brought into close contact with each other, the wheels are straddled over the basic rails 20 and the tongue rails 21, and point switching is performed so that the leading end of the tongue rails is switched to another lane. The height a from the top of the basic rail to the top of the tongue rail, the point A 14 mm below the top of the basic rail, and the outside of the top of the tongue rail The horizontal distance b with the end B on the gauge side was measured, and when they were larger than a predetermined value, they were replaced.

In the case of FIG. 7, the horizontal distance b is smaller than the tongue rail top width. The basic rail is shown in Fig. 5.
As shown in FIG. 8, when the tongue rail top surface is lower than the base rail top surface by 14 mm or more, the value between points A and B in FIG. 8 is measured as b.
In this case, the horizontal distance b is a value larger than the tongue rail head width. When the tongue rail top surface is 14 mm or less from the base rail top surface, that is, above the point A, the tongue rail top width is measured as the horizontal distance b as it is.

[0004]

Conventionally, such a measurement of the basic rail and the tongue rail has been performed by using a combination of a right angle ruler and a metal ruler. However, the measurement position is 14 mm lower than the top surface of the basic rail. Since the position is a position, it is difficult to determine the position of the ruler, read the scale, and the like, so that it is very difficult to measure. The measured value varies depending on the measurer, and the measurement is often performed at night.

The present invention has been made to solve the above-mentioned problem, and has as its object to provide a digital tongue rail tip wear measuring instrument capable of easily and accurately measuring the amount of wear.

The slider 2 also slides, and the amount of movement is detected and displayed on the display panel 6, whereby a is measured.

Next, a description will be given of the determination of wear of the tongue rail tip. The tongue rail tip wear measuring ruler 16 is used to determine the tongue rail wear limit. Factors that may cause derailment from climbing at the point of the vehicle are mainly caused by wear of tong rails, basic rails, and wheel flanges, etc. Even when the wear has not reached the limit, there is a possibility that derailment may occur due to the overlapping of bad conditions with the wear shape of the wheel.

For this reason, the tongue rail tip wear measuring ruler 16 is formed following the worst flange shape 31 in which the wheel flange of the wheel 30 shown in FIG. FIG. 5 (b) shows the shortest distance from the corner point (the tongue rail tip wear measurement ruler is not a perfect curved surface but a polygonal cross section and indicates a corner point near the tip of the flange inner surface) to the flange tip. When the angle between the wear portion on a straight line and the plane of the inner surface of the wheel is 17 ° or less, the shortest distance from the corner point to the tip of the flange is 1.5 mm or less. It is.

The ruler 16 having such two shapes is attached to the measuring instrument of the present invention, and as shown in FIG.
First, the ruler shown in FIG. 5C is applied to each position of the tip of the tongue rail. The ruler should be applied so that the upper surface of the ruler is horizontal and the ruler top surface and the side surface of the basic rail or tongue rail are tightly closed. The position of the corner point between the top of the tong rail and the ruler is checked. If the position of the corner point is below the top of the tong rail, it is normal.

However, when the position of the corner point is higher than the top surface of the tongue rail, it indicates that the tongue rail has worn out and it is time to replace it. In this case, the same determination is further performed using the ruler shown in FIG. 5B. If the corner point position is higher than the top surface of the tongue rail, there is a possibility of getting on and derailing. It is clear that there is a need for rail replacement.

[0016]

As described above, according to the present invention, since the measurement of a and b and the measurement of tongue rail wear are integrated, and the display is digital, the measurement can be easily performed. The reading error by the operator is also eliminated, and the wear control of the tip of the branching device can be properly performed.
A great effect can be obtained.
