Description

[Detailed description of the invention]

The present invention relates to a trajectory alignment IL method and device. There is a straightening IF of a curved part and a straightening of the own track. First, let's explain the straightening of a curved part. Figure 1 shows the amount of lateral displacement of the track, etc. A diagram for explaining the definition of ``Inclination of a curved section of a dovetail track.'' Let the rail of /j be the reference rail, represent it as an arc S of radius R, and put the reference line KM of length α at both ends of the rail. - M is located on the arc SF, and the reference line K is placed at ~1 from the center point 1 of M to the reference line.
If the white where the double line intersects with the arc S is N, then the quality of N1 is the lateral displacement amount V-< of the arc S with respect to the reference line KM. If this lateral displacement amount (■) is very small compared to the radius of the arc S, then V=n2. 'It is possible to find the transverse change A◇-\/- from BR. Also, at a point other than the center point on the reference line KM, for example, at a point L' where the length of the reference line KM is divided into length a and length b, Mll line t<5'/ , '(If the point where the perpendicular line intersects with the arc S is N', the length of l'N' is the lateral displacement IV' of the N9 point on the arc S relative to the reference line KM.This N1 point If the lateral displacement v9 of the arc S is very small compared to the radius R of the arc S, the lateral displacement V' of the N1 point can be found from Vl-ab/2R. In Figure 1, take a point P along the length of the single line KM, take KP as a reference, and at point P,!!
Let Q be the point where a perpendicular line drawn on the side of the arc S to the directrix KP intersects with the arc S, then the length of PQ is the arc S with respect to the reference line KP.
The amount of lateral displacement of the Q point above is V'' (゛.If MP=C,
If the amount of lateral displacement V'' at point Q is very small compared to the radius R of the arc S, the amount of lateral displacement V'' at point Q can be calculated from V'' = C(L + C)/2R. The above-mentioned lateral displacement amounts v, v', and VII can be converted into lateral displacement lines relative to the same reference line using the properties of circular curves.Therefore, in the following explanation, ,
When sifting, averaging, and comparing the lateral displacement amounts v, v", and v", a ring converted into a lateral displacement i with respect to the same reference line is used. Conventionally, as shown in Fig. 2, when straightening a curved part of the track with radius 1 < by using S as the reference rail and K M 4 declination line, the Mrf line K M The front end K of the track is placed on the standard rail S' of the unregistered part of the track, and the rear end part M is placed on the ht semi-rail s-1 of the unregistered part of the track, and the reference line K
N1 along U-rule S (while moving U, measure the lateral displacement amount V or V'' of the straightening point of the curved part of the track,
Compare this measured lateral displacement amount V or Vl with a preset set lateral displacement - to determine the amount of correction at the point to be corrected,
It is the amount of adjustment of A. It is a horizontal movement of 1 rule! (, the track was being straightened. Therefore, the amount of lateral displacement of the rail of the track that has already been straightened will be affected by the subsequent straightening work of the unleveled track i1-. Even if it changes, it is difficult to grasp the changed state of the trajectory. Ah, this is the soil. Conventionally, only one of the 46 left and right rails that constitutes the track is connected to the base rail S.

[Measurement + [lyl] M11! There was a drawback that only the street alignment on the rail S side could be accurately performed. In particular, there are deviations in the gauge of eight rails, so if only one rail is used as a reference as in the past, the deviation in the gauge will accumulate on the rail on the opposite side, and There was an inconvenience that the rail path was not smooth. The present invention consists of 1. Since this was done to eliminate the defects listed in L, the amount of adjustment for the reference rail was determined from the condition of the track in the unregistered part and the completed part, and the adjustment amount between the V standard rail and the opposite rail was calculated. By measuring the discrepancy in the track spacing and adding or subtracting 1/2 of this gauge discrepancy or slack amount to the adjustment amount to calculate the final adjustment amount, it is possible to smooth out the unrealigned portions and the completed adjustment portions of the track. It is an object of the present invention to provide a method and device for straightening a track, which can evenly straighten the left and right rails. An embodiment of the present invention will now be described in detail with reference to the drawings. Fig. 3 is an explanatory diagram showing the structure of one of the rails in the present invention, Fig. 4 is a side view of a device according to an embodiment of the present invention installed on a track straightening machine, and Fig. FIG. 2 is a schematic diagram of the device shown in FIG. In Figs. 3 to 5, the same number 1 means the same parts. In Fig. 3, when a track straightener (not shown) having a tail QL line 13 and a sub reference line 16 moves on the orbit in the direction of arrow The main reference line 13 is controlled so that the amount of lateral displacement of one point of the main reference line 13 with respect to the rail is always zero using the rail 1 of [17] as a reference rail. In the unaligned part of the track, measure the lateral displacement IV2 at 13 points on rail 1 and at the sub-reference line 16, and in the finished part of the track, measure the lateral displacement IV2 at 13 points on rail 1 and at 1 point tIL on rail 1.
