Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a measuring section and a straightening section, and while the measuring section measures the amount of displacement of the object to be straightened from a reference line, the straightening section measures the amount of displacement of the object to be straightened from a reference line. The present invention relates to a method of controlling a straightening device that straightens a straightening device.

Conventionally, when a straightening device corrects an object to be straightened, a measurement unit measures the amount of displacement of the point to be straightened from the reference line of the object to be straightened, and the reference line of the point to be straightened is used. A straightening device that calculates a target straightening amount from the difference with a set value from and straightens the object to be straightened using a straightening section so that the straightening amount at a point to be straightened is equal to this target straightening amount. A control method was used.
However, in this method, if the target adjustment amount is too large, strain may occur on the object to be adjusted, deforming or damaging the object, or separating the already adjusted part of the object and the unregistered part. There were disadvantages such as the parts were not connected smoothly and therefore the adjustment had to be repeated from the beginning.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and uses a straightening device to measure the amount of displacement of the point to be straightened from the reference line of the object to be straightened, and to use this measured value and the Calculating a target correction amount for the point to be corrected from a set value from a reference line of the point to be corrected, and setting a correction rate based on the target correction amount;

The sampling and holding unit 4 holds the measured value of the point to be straightened on the object to be straightened, and this held measured value is designated as My. and this measurement
My is output to the first arithmetic unit 6 and the second arithmetic unit 7. The first computing unit 6 inputs the output My of the sampling hold section 4 and the set value Ys from the reference line of the point to be leveled of the object to be leveled which is set in advance to the setting device 8, and inputs the target leveling amount ( My−Ys) and outputs it to the third arithmetic unit 9. The third computing unit 9 receives the target adjustment amount (My-Ys) from the first computing unit 6.
Then, a preset correction rate α is inputted from the correction rate setting device 10, and a correction adjustment amount (My-Ys) α is calculated. This calculation result is displayed on the display 11, and the fourth calculation The signal is output to the device 12. Therefore, the operator initially sets the correction rate α=1 to the display 11.

Next, a case will be described in which the above-described control method for a straightening device is applied to a straightening device of a track straightening machine that straightens the track of a railway track.

In general, track adjustment performed by a track adjustment machine includes height adjustment to correct vertical deviation in the longitudinal direction of the top surface of the track rail, and correction of height deviation of the left and right rails of the track. There is leveling and straightening to correct left and right deviations in the longitudinal direction of the gauge line of the track rail. Normally, in track alignment work, one of the left and right rails is used as a reference rail, and the height of the reference rail is first adjusted for each sleeper, and then the height of the reference rail is compared to the adjusted reference rail. to level the other rail, then level the left and right rails, and use the bed tamping device installed on the track straightening machine to tamp the ballast track bed on the underside of the sleepers to complete the track straightening work. complete. in this case,
If the amount of elevation adjustment or the amount of street adjustment is too large, it may deform or damage the fastening device between the rail and the sleeper, and the leveled and unleveled portions of the track may not connect smoothly, especially When straightening the track, if there are structures such as bridges or railroad crossings on the track that cannot be straightened with a track straightening machine, it is necessary to smooth the rails fixed to these structures and the rails of the straightened track. This results in the inconvenience of not being able to connect to the machine and having to start the alignment work all over again. In such a case, if the control method of the straightening device of the present invention is applied, the above-mentioned inconvenience can be avoided.
Below, a case will be described in which the method for controlling the straightening device of the present invention is applied to straightening work along a track.

Figure 5 is an explanatory diagram of straightening the straight section of the track.
It is an enlarged view of part B in the figure.

In FIG. 2, a track straightening machine 21 running on rails 20, 20' is provided with a straightening device 22 for straightening the track, a reference line 23 using a light beam or a steel wire, etc. The straightening device 22 includes a measuring section 24 that measures the amount of track misalignment with respect to the reference line 23, and a straightening section 2 that straightens the rails 20, 20'.

0, and this measured versine value is equal to the versine value when the rail 20 with respect to the reference line 23 is a correct circular arc 26 (indicated by a dashed line in the figure) with a predetermined radius of curvature R. This is done by simultaneously moving the rails 20, 20' fastened to the sleepers by the fastening device to the left or right by the straightening section 25 so that That is, in FIG. 3, both ends of the outer rail 2
0 is the midpoint of the reference line 23, and at this midpoint M, the points where the perpendicular line drawn to the reference line 23 intersects the arc 26 and the rail 20 are N and P, respectively.
If the length of the reference line 23 is l, the versine value of the arc 26 is MN=l ² /8R, the versine value of the rail 20 is MP, and with MN=l ² /8R as the set value, MP=MN. Adjust the rails 20, 20' so that Now, the first

If these correspond to the measuring section 24, the straightening section 5, and the straightening device 22 of the track straightening machine 21 shown in FIG. 2, then FIG. 22 is a block diagram of a control method for the straightening device 22 when applied to the straightening device 22. That is, in Figure 2,
On the rails 20, 20', from the sleeper 27 at the point where straightening has been completed toward the sleeper 28 at the point to be straightened,
The measurement unit 24 measures the versine value with respect to the reference line 23 of the rail 20, and while outputting the measured value y to the sampling hold unit 4, the track straightening machine 21
When the center of the straightening section 25 reaches approximately the center position of the sleeper 28, which is the point to be straightened, the track straightening machine 21 is stopped, and a control device (not shown) for the track straightening machine 21 is activated. , the hold signal 5 is output to the sampling hold section 4, and the rail 2 at that position is output.
The masaya value MP of 0 is held in the sampling hold section 4. This held Masaya value is My

is set, and it is determined whether the target correction amount (My-Ys) outputted from the third calculator 9 and displayed on the display 11 is appropriate. If this target adjustment amount is too large, rail 2
0, 20', there is a risk of deforming or damaging the fastening device between the rails 20, 20' and the sleeper 28, and the unaligned portion of the rail 20, 20' in front of the sleeper 28 and the rear part of the rail 20, 20' There is a risk that the pre-aligned parts may not connect smoothly, and the rail 20,
There are structures such as bridges and railroad crossings in the unleveled area ahead of the sleeper 28 at 20', and the rails fixed to these structures and the already leveled rails behind the sleeper 28 connect smoothly. If there is a possibility that you cannot
Taking these circumstances into consideration, a correction coefficient α (<1) is set and output to the third computing unit 9, and the target correction amount (My−Ys) is multiplied by the correction coefficient α to perform correction correction. The third calculator 9 calculates the quantity (My-Ys) α, and outputs the calculation result to the fourth calculator 12. Also,
The versus value of the point P on the rail 20 that is being adjusted by the adjustment section 25 of the adjustment device 22 is measured by the measuring section 24, and the measured versus value y and the versus of the output of the sampling hold section 4 are measured by the measurement section 24. The value My is the second arithmetic unit 7
The actual adjustment amount (My-y) at point P on the rail 20 is calculated and output to the fourth calculator 12. The fourth arithmetic unit 12 is the second arithmetic unit 7
(My−y) and the output of the third arithmetic unit 9 (My
−Ys) α, and the adjustment deviation amount Y=(My−y)−
(My-Ys)α is calculated and output to the straightening section 25 of the straightening device 22, and when the straightening deviation Y becomes zero, that is, (My-y)=(My-Ys)α The straightening device 22 may be controlled so that the straightening work is completed when the straightening operation is completed. When the straightening work is completed, as shown in FIG. 3, point P on the rail 20 moves to point Q in the middle of PN, and the rail 20 moves to point Q, which passes through point Q.
(indicated by a dashed line). Therefore, deformation or damage to the fastening device is prevented, and the rails 20, 20'
It is possible to smoothly connect the already leveled part and the unleveled part or the rail fixed to the structure such as the bridge or railroad crossing.

In addition, when performing alignment on the straight section of the track,
In the case of straightening the curved section as described above, we can consider that the radius of curvature R has become infinite, so Ys
=MN=l ² /8R=0. Therefore, if MN=Ys=0 in FIGS. 2 and 3, then FIG.
In the figure, FIG. 3 corresponds to FIG. 5, and the straightening of the straight portion of the track can be performed in the same way as the straightening of the curved portion of the track.

As described above, the control method of the straightening device of the present invention is based on the target straightening amount (My−Ys) of the output of the first computing unit.
is input to the third computing unit, the target adjustment amount (My-Ys) is monitored on the display, and if necessary, an appropriate correction rate α is set in the correction rate setting device, and input to the third computing unit. Then, in the third computing unit, the correction adjustment amount (My
−Ys) α and outputs the calculation result to the fourth calculation unit. Further, the second arithmetic unit calculates the actual correction amount (My-y) and outputs the result of the calculation to the fourth arithmetic unit. The fourth calculator calculates the adjustment deviation amount Y= from the actual adjustment amount (My-y) input from the second calculator and the corrected adjustment amount (My-Ys) α input from the third calculator Calculate (My-y)-(My-Ys)α, output the calculation result to the straightening section of the straightening device,
Since the straightening device is controlled so that the straightening work is completed when Y becomes zero, the points to be straightened on the object to be straightened can always be straightened by an appropriate correction amount. Therefore, it is possible to smoothly connect the already-aligned part and the un-aligned part without straining the object to be adjusted, deforming or damaging the object, and so on.
