問題である。2. Description of the Related Art There are two types of deviations in railroad tracks: deviations and deviations. Passage means the bending of the rail with respect to the longitudinal direction of the rail on the track plane, and when an appropriate rail length, for example 10 m, is taken and a measurement string is tied between them with a piano wire or the like, It is defined as a deviation of the distance between the measurement string and the rail (the arrow) at the center point (the arrow point) of the measurement string.
Also, the ups and downs are defined as the ups and downs of the rail. When such a deviation occurs,
As the gap between the train wheel and the rail increases, train vibration and rattling increase, which causes problems such as inability to ride comfortably and high-speed traveling. Therefore, the measurement of track deviation and its correction are extremely important tasks for train operation. Especially, 270 to 300 per hour
This is an extremely important problem in the orbit for high-speed vehicles such as the Shinkansen, which is aiming to achieve speedup of Km / H.

掛りな設備を必要とする等の問題があった。Conventionally, a track inspection car has already been put into practical use as a device for measuring the deviation of a track. In this track inspection vehicle, the deviation of the track is automatically measured by various methods. However, due to the nature of the track inspection vehicle, it is necessary to put the inspection vehicle into the track for inspection, and to operate the inspection vehicle by putting it in and out of the track based on the train operation schedule. There has been a problem in that extremely large-scale equipment is required, such as the provision of a lead-in line and a retreat line.

ようにしている。Therefore, conventionally, a worker manually measures by dividing a predetermined section and corrects the trajectory deviation based on the measured data at a later date. Thus, in the past, the measurement of the trajectory deviation was carried out by using a general transit as a surveying instrument when the straight section was out of alignment, and the level deviation was also measured by using a general level as a surveying instrument. Is going. On the contrary,
To measure the deviation of the curved portion, for example, set a short fixed interval of 10 m or 20 m, etc., and put a measurement string on the inner surface of the outer rail with a piano wire, and measure the measurement string at the halfway point (straight arrow point). The distance between the outer rail and the inner surface of the outer rail (arrow) is measured, and the measurement result is compared with the reference value of the arrow at the time of design. Then, from this measured point, a straight arrow is moved forward by a predetermined interval to measure a straight arrow, and this is repeated to measure the deviation of the curved portion of the point at each predetermined interval.

また所定距離ごとのスポット的な通り狂いの測定である
ため、測定点間の通り狂いについては無視されており、
精密なものではなかった。However, in the conventional measurement of the deviation of the curved portion, the measurement strings are stretched by dividing an extremely short distance from the viewpoint of controlling the trajectory such as 10 m or 20 m. This is because when the distance is increased, the measurement string of the piano wire or the like is bent and the measurement result becomes inaccurate. Therefore, in a curved portion of a track that runs at high speed such as a bullet train, the curvature of the curved portion is extremely large at a radius of 4000 m, but the deviation of the curved portion having a short distance is measured. There was a risk that the passing would be inaccurate. Therefore, it has been desired to develop a measuring device capable of measuring deviation in a long distance span.
In addition, because it is a spot-like measurement of deviations at predetermined distances, deviations between measurement points are ignored.
It wasn't precise.
【０００６】一方、従来の直線部の通り狂いの測定と、

的な測定しか行えず、精密なものとは言えなかった。On the other hand, the conventional measurement of the deviation of the straight line portion,
Since the high and low deviations are measured by using the transit and the level, respectively, this can only be measured in a spot-like manner only at the measurement points, and cannot be said to be precise.

The spot of the laser light that has reached the laser light receiving scale plate 7 is located at the center point of the upper and lower scales and the left and right scales of the laser light receiving scale plate 7, and the locus of the laser light is located on the extension line of the rail 2a. The left and right positions of the laser emitter 5 and the elevation angle are adjusted.
This completes the preparation for measuring the deviation in the straight section. The spot of the laser beam is projected on the monitor 9 through the television camera 8. The monitor 9 is connected with an automatic tracking measuring device for the spot and a personal computer as required.

向を見るだけでよい。The measurement is carried out with the laser light emitter 5 fixed.
The receiving side carriage 4 is intermittently moved by a predetermined distance such as m or continuously moved to bring the laser light receiving scale plate 7 close to the laser light emitting device 5. As a result, if the measurement point of the rail 2a in the straight line portion is misaligned or uneven, the position of the spot of the laser light received by the laser light receiving scale plate 7 deviates from the center point in the vertical and horizontal directions. .. Therefore, the measurer may plot the deviation in which direction while looking at the monitor 9. Further, in the monitor 9 to which the automatic tracking measuring device and the personal computer are connected, it is possible to automatically track the deviation of the spot and input it to the computer. After that, the laser light receiving scale plate 7 is sequentially moved in the above-described manner to measure the deviation and height deviation of the linear rail 2a. By continuously measuring the deviation of the straight rail 2a, it is possible to detect the location where the straight portion changes to the curved portion, as shown in FIG. All that is required is to look at the tendency of the change in the deviation amount.

In this case, first, in the same manner as in the measurement of the straight line portion, the laser light emitter 5 and the laser light receiving scale plate 7 in the straight line portion are set apart by a distance of, for example, 150 m, and the laser light emitted from the laser light emitter 5 is irradiated. Stretch the measurement string with light. The spot of the laser light from the laser emitter 5 is shown in FIG.
As shown in, the position of the laser light receiving scale plate 7 is adjusted so as to come to the center point of the laser light receiving scale plate 7. In addition, the laser light emitter 6 in the curved portion is set apart from the laser light emitter 5 in the straight portion by, for example, 2 m in a direction orthogonal to the longitudinal direction of the rail 2a. Then, from this state, the laser light is emitted from the laser light emitting device 6 in the curved portion toward the laser light receiving scale plate 7, and the spot of this laser light is located below the center point of the laser light receiving scale plate 7 by a predetermined height. Then, the azimuth angle and the elevation angle of the laser light emitter 6 in the curved portion are adjusted so as to be located on the center line in the left-right direction (see FIG. 8).

一列に揃った場所を捜せばよく、極めて容易である。To measure the deviation of the curve and the deviation of the curve, the laser receiving scale 7 is moved from the set state to the laser emitter 5 side as shown in FIG. The distance between the container 5 and the laser receiving scale plate 7 is 1 which is the initially set distance (150 m in the above-mentioned embodiment).
It becomes / 2. That is, the laser receiving scale plate 7
Is located at the midpoint of the arc of the measurement string. And FIG.
As shown in, the laser light emitting device 6 for measuring the curved portion is moved to the side of the laser light emitting device 5 for measuring the linear portion so as to be 1/2 of the initial set distance (2 m in the above-described embodiment).
That is, the laser light emitted from the laser light emitting device 6 for measuring the curved portion is made to pass through the midpoint (straight arrow point) of the measurement string. As shown in FIG. 9, the setting of the position of the right arrow point is as follows.
It is very easy to find a place where the spot from the laser light emitting device 5 for measuring the straight line portion and the spot from the laser light emitting device 6 for measuring the curved line portion are aligned in the vertical direction, which is extremely easy.

とを測定することが可能である。Therefore, the deviation of the trajectory of the curved portion is measured in the vertical direction of the laser beam spot of the laser emitting device 6 for measuring the curved portion, which is focused on the laser receiving scale plate 7 located at the midpoint of the arc of the measurement string. It is sufficient to measure the positional deviation dimension in the horizontal direction. The positional deviation of the spot of the laser light in the left-right direction is the size of the straight arrow. Therefore, when the measured size of the straight arrow is compared with the size of the regular straight arrow at the time of designing, the error becomes clear, and the error becomes inaccurate in the curved line portion. Further, the positional deviation of the laser light spot in the vertical direction is the deviation in height of the curved portion itself, and the deviation dimension itself may be measured. Accordingly, it is possible to measure the deviation of the curved portion at the midpoint of the arc of the measurement string and the deviation of the height.

It is the same as in the case of the straight line portion that the measurement is intermittently performed at equal distances or continuously.

It is 5. Further, the side surface portion does not come into contact with the wheel, and therefore does not wear. Therefore, when measuring the wear of the outer rail 2a, the track deviation measuring device 1 is set in contact with the left and right side surfaces of the outer rail 2a, and the track deviation of the curved portion is once measured and set according to the normal procedure described above. Then, the rail wear measuring element 20 shown in FIG.
