2. Description of the Related Art When a train travels on a rail, a train load, a driving force, and the like act on the rail through wheels, and the texture of the rail surface changes due to metal fatigue. If such metal fatigue is left as it is, there is a problem that the rail may be broken, the rolling noise of the wheel may be increased, or the corrugated wear may progress.

For this reason, the surface of the rail is adjusted to 0.1 to 0 by a grinding device such as a grinder every predetermined period (for example, every time the cumulative total number of trains passing by exceeds 50 million tons). A new metal structure that has not been subjected to metal fatigue is exposed on the surface by grinding in a range of 0.3 mm.

[0004] Such a grinding operation of the rail surface is performed by repeating the polishing apparatus mounted on the carriage while reciprocating on the rail, and the grinding amount of the rail is also 0.1 mm unit. It is extremely severe. In addition, if the rail correction amount is large, useless rail wear is promoted, the rail life is shortened, and the rail replacement work is forced early. Therefore, it is natural that the shaving amount should be as small as possible. For this reason, the shaving operation is performed while measuring the rail shaving amount for each polishing.

Is moved forward to the fixture body 15 on the fixed side, and the installation portion 27 is brought into close contact engagement with the rail jaw 26 on the outer rail side by the pressing force (clamping force) of the clamp device 23. As a result, the rail wear measuring device 14 comes into tight contact with the four front and rear installation portions 18 and 27 on the jaws 17 and 26 on the inner and outer rail sides of the rail, so that the mounting is stable. Is obtained. In the vertical direction of the rail 5, the rails 5 are pressed by the accumulated elastic force of the spring 21, and in the horizontal direction of the rail 5, they are pressed by the pressing force of the clamp device 23. For this reason, the rail wear measuring device 14 is rigidly fixed to the jaws 17 and 26 as the measurement reference surfaces in a one-touch manner.

After the installation of the rail wear measuring device 14 is completed, the thimbles 19a,
The predetermined dimensions may be measured by operating the 20a and the ratchet handles 19b and 20b. In the micrometer 19, by rotating the thimble 19a, the meter spindle 19c, which is the measurement contact point, is moved to a position 2 to 3 mm from the upper surface of the rail, and then the ratchet handle 19b is rotated to operate the meter spindle 19c. Is brought into contact with the upper surface of the rail until a predetermined torque is obtained. When the torque reaches a predetermined value, the ratchet handle 19b clicks idly, and the displayed numerical value at that time may be read. The wear amount is previously input to the micrometer 19 so that the reference dimension of the rail 5 from the center of the rail head 11 to the R surface portion 12 is “0”,
When the R surface portion 12 is worn, only that amount is negatively displayed.

Thereafter, the wear amount of the rail top surface 13 of the micrometer 20 is measured in the same manner as in the case of the micrometer 19 described above. In this case, the micrometer 20 is input such that the reference dimension of the rail 5 from the horizontal line connecting the centers of the jaws 17 and 26 as the measurement reference plane to the rail top surface 13 is “0”. Therefore, when the rail top surface 13 is worn, only that amount is negatively displayed.

As described above, the rail wear measuring device 14 according to the present embodiment connects the fixed-side instrument main body 15 and the movable-side instrument main body 16 to the jaws 17, 26 serving as the measurement reference plane of the rail 5.
Anyone can attach to the rigid without error by one-touch operation.
Due to a synergistic effect with the use of 9 and 20, the measurement error becomes ± 2 μm, which is extremely high precision. Further, when the type of the rail 5 is changed, it is only necessary to reset the data of the reference dimension of the corresponding rail to the micrometers 19 and 20, and it is not necessary to prepare a measuring device for each rail type.
