[Industrial applications]

 The present invention relates to a digital tongue rail tip wear measuring device for measuring the amount of wear necessary for managing wear of a tip of a branching device.

[0002]

[Prior art]

 FIG. 7 is a diagram for explaining a method of determining the replacement timing and measuring the wear amount from the tread surface of the wheel in the meshed shape of the existing basic rail and the tongue rail. In order to branch a vehicle running on a predetermined rail to another lane, as shown in FIG. 7, the tongue rail is closely attached to the basic rail 20 so that the wheels straddle the basic rail 20 and the tongue rail 21. Points are switched so that passengers can get in and change from the tip of the tongue rail to another lane. The height a from the top surface of the basic rail to the head of the tongue rail, the point A 14 mm below the top surface of the base rail, and the outside of the top surface of the tongue rail are used to determine the replacement time of the base rail and tongue rail. The horizontal distance b from the rail-side end B was measured, and if they were larger than a predetermined value, they were replaced.

In the case of FIG. 7, the horizontal distance b is smaller than the crown width of the tongue rail. If the basic rail is worn as shown in Fig. 5 and the top surface of the tongue rail is 14 mm or more lower than the top surface of the basic rail, measure the value between points A and B in Fig. 8 as b. is doing. In this case, the horizontal distance b is larger than the tongue rail head width. When the tongue rail crown surface is 14 mm or less from the basic rail crown surface, that is, above the point A, the tongue rail crown width is measured as it is as the horizontal distance b 1.

A scale 7 is attached to the ruler body 1, and a slider 2 is slidably attached to it. A display panel 6 is provided on the slider 2, and the relative movement amount between the ruler body and the slider is mechanically, electrically or optically detected and converted into an electric signal, which is digitally displayed on the display panel 6. Has become. The display panel 6 can digitally display up to 0.01 mm, the measuring range is 0 to 150 mm, and one button type silver oxide battery is used as the power supply, and it has a life of about 2 years in normal use. Further, an ON switch 8 and an OFF switch (power switch) 9 are provided so that the ON switch 8 can set the displayed value to zero. Further, a data hold switch 5 is provided so that the detected data can be held by operating the switch 5, and the measured data can be taken out from an output terminal (not shown). A b-measurement bar 10 is provided at the tip of the ruler body 1 so that it can be slid vertically and can be fixed in position by a fixing knob 11. On the other end side, a ruler body 16 for measuring the tongue rail wear is attached to the ruler body 1 so as to be rotatable by 90 ° about a pin 17, and one end is attached to the slider 2 to interlock with the slider. A measuring bar 15 is provided slidably with respect to the ruler body.

Next, b measurement will be described with reference to FIGS. 2 and 3. As shown in Fig. 2, place the measuring device at right angles to the rail, place the rail bracket 4 on the side of the rail, and turn the measuring bar 10 on at point A, which is 14 mm below the top surface of the basic rail. The display is set to zero by the switch 8. Next, as shown in FIG. 3, slide the ruler body 1 while keeping the slider 2 as it is, and slide the bar for measurement b up and down to position the tip at the top end B of the tongue rail 21. , B is measured. At this time, the amount of movement of the ruler body 1 is detected and digitally displayed on the display panel 6. Even if a is 14 mm or less, it can be measured by sliding the b measuring bar 10 up and down. The measured value is held by pressing the digital hold switch 5.

Next, the measurement of a will be described with reference to FIG. As shown in FIG. 4, the measuring device is set upright, the tongue rail wear measuring ruler 16 is rotated 90 °, and its surface is applied to the top surface of the basic rail. In this case, the stopper 18 hits the ruler body 1 so that the basic rail and the measuring instrument are held at a right angle. Next, slide the measurement bar 15 to align the tip of the bar 15 with the top surface of the basic rail and zero-set the display of the rider, and then touch the tip B of the tongue rail top surface. Along with the slide of the a measurement bar, the slider 2 also slides, and the amount of movement is detected and displayed on the display panel 6, whereby a is measured.

Next, the tip wear determination of the tongue rail will be described. The tongue rail tip wear measuring ruler 16 is used to determine the tongue rail wear limit. Factors that may cause derailment at the point of the vehicle are wear of the tongue rail, the basic rail, and the wheel flange.However, from the examples of derailment accidents that occur at the point, the basic rail and the tongue rail Even if the wear of the wheel has not reached the limit, derailment may occur due to adverse conditions overlapping with the wear shape of the wheel.

Therefore, the ruler 16 for measuring the wear of the tip end of the tongue rail is made following the worst flange shape 31 in which the wheel flange of the wheel 30 shown in FIG. 5A has reached the wear limit. Fig. 5 (b) shows the shortest distance from the corner point (the ruler for measuring the wear of the tip of the tongue rail is not a perfectly curved surface but has a polygonal cross section, and refers to the corner point near the tip of the inner surface of the flange) to the tip of the flange. When the distance is 3.0 mm or less and the angle between the linear wear portion and the plane of the wheel inner surface is 17 ° or less, Fig. 5 (c) shows that the shortest distance from the corner point to the flange tip is 1.5 mm or less. It is a thing.

The ruler 16 having such two kinds of shapes is attached to the measuring instrument of the present invention, and as shown in FIG. 6, first, the ruler of FIG. 5C is applied to each position of the tip of the tongue rail. When applying the ruler, make sure that the top surface of the ruler is horizontal and that the top surface of the basic rail and the side surface of the basic rail or tongue rail come into contact with each other without any gap. Check the positions of the top surface of the tongue rail and the corners of the ruler, and if the position of the top corner is below the top surface of the tongue rail, it is normal.

However, when the corner point position is above the top surface of the tongue rail, it indicates that the tongue rail has been worn away and it is time to replace it. In this case, the same judgment is made using the ruler in Fig. 5 (b), and if the corner point position is higher than the top surface of the tonguel top, it may cause a derailment due to riding up. It turns out that there is an urgent need for rail replacement.
