Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a level recording method for a track straightener for recording the finished leveling of railway tracks.

Conventionally, track straightening machines have been used to straighten the height difference, or level, between the left and right tracks on railway tracks to a predetermined amount.
For example, multiple tyampas are known. In such a straightening machine, it may be required to record the level before and after straightening. For this purpose, a front level and a rear level are installed at the front and rear of this track leveling machine, respectively, and a lifting device and a tamping device are used to adjust the level between the two levels, and the output of each level is recorded. It is considered to do. However, the values output by both levels at the same time are the levels at positions separated by the distance between the front and rear levels on the orbit, so from this recorded result, we can compare the levels before and after adjustment at the same orbit position. The problem was that it was difficult to read the data and the reading process took a long time.

The present invention has been made in view of the above circumstances, and provides a level recording device for a track straightening machine that can record the levels before and after straightening in parallel corresponding to the same track position, and allows easy reading of changes in the level before and after straightening. The purpose is to provide

According to the present invention, this purpose is to provide a front level device and a rear level device for detecting the height difference between the left and right tracks, and a front and rear level device for detecting the height difference between the left and right tracks.
In a track adjustment method that includes a climbing device and a tamping device installed between the rear levelers, and levels the track while repeatedly running and stopping, while traveling while recording the output of the front leveler, The recorded output of the front level is read out with a delay of the distance of the front and rear level, and the output of the front and rear level for the same position on the orbit is output and recorded in parallel to the same time axis. This is achieved by the level recording method of the track straightener. The present invention will be explained in detail below based on the illustrated embodiments.

FIG. 1 is a side view of the track straightening machine, and FIGS. 2 and 3 are a sectional view taken along the - line and a sectional view taken along the - line.
In these figures, reference numeral 10 indicates a front carriage, and numeral 12 indicates a rear carriage, two of which are provided on each side. 14 is a vehicle body. 16, 16a, 16b are a pair of left and right tracks, 18 is a front level provided in front of the front vehicle 10, and 20 is a rear level provided between the rear vehicles 12. The front and rear standard devices 18 and 20 are the left and right small vehicle transports 22, 22a, 22b, 24, 24a, 24, respectively.
It detects the inclination of the axles 26 and 28 that connect the axles 26 and 28, and is configured to detect, for example, the inclination of a pendulum as an analog signal using a potentiometer or the like. A mileage detector 30 is disposed near the axle 28 of the rear level indicator 20, and the rotation of the axle 28 is transmitted to this detector 30 via a small gear. This detector 30 sequentially outputs running pulses P corresponding to a predetermined amount of rotation of the vehicle 24. That is, the running pulse P outputs a logic 1 digital signal every predetermined amount of the track straightening machine.

In Fig. 1, 32 indicates the front and rear levels 18, 20.
It is a climbing device installed between the left and right tracks 1.
Each track 16a, 16b is raised so that the difference in height, that is, the level, between the tracks 6a, 16b becomes a predetermined amount.
For example, when the left track 16a is used as a reference, the lifting device 32 lifts the right track 16b, and when the right track 16b is used as a reference, the left track is lifted by a predetermined amount. A tamping device 34 is provided at the rear of the hoisting device 32, and tamps the lower part of the sleeper on the track 16 lifted by the hoisting device 32.

The front level 18 of this track leveling device detects the level of the unaligned track, and the rear level 20 detects the level after the leveling.

FIG. 4 is a configuration diagram of a level recording device according to the present invention;
FIG. 5 is a flowchart showing the operation of the digital arithmetic unit used therein. In Figure 4,
40 is an analog signal A which is the output of the front level indicator 18
This is an A/D converter that converts the signal into a digital signal _A0 . This A/D converter 40 constantly outputs a digital signal _A0 .

44 is a digital arithmetic unit, which includes a built-in memory means consisting of a large number of writable and readable memories (RAM). The required amount of this memory is
The number of travel pulses output by the travel distance detector 30 within the distance L between the front and rear level gauges 18 and 20 is set to N, for example, N = 400, and each memory has a fixed address from 0 to 400. It is being As will be described later, the computing unit 44 sequentially writes the digital signal _A0 of the front level indicator 18 as A(I) into the memory at address I every time the traveling pulse P becomes logic 1, and also writes the digital signal A0 of the front level gauge 18 as A(I) in the memory at address I, and also writes the digital signal A0 of the front level gauge 18 as A(I) every time the traveling pulse P becomes logic 1. Read A(IN) sequentially.

The operation of the arithmetic unit 44 will now be explained with reference to FIG. When the device first starts, the steps
Initial conditions are entered at 100. That is, the memory address I is set to 0, and the number of running pulses N=400 corresponding to the distance L is input. Arithmetic unit 44
The built-in memory means stores the digital signal A ₀ output by the A/D converter 40, that is, the pre-level indicator 18.
Write the digital signal A ₀ which is obtained by converting the analog output signal A of
The address is stored in the memory as A(0) (step 104). Next, it is determined whether I=N (=400), that is, whether the traveling distance has reached L (step
106), if I<N (=400), wait until the travel step P becomes logic I (step 108), and set I to 1.
(Step 110). Steps 102 to 110 below
By repeating the operation, 400 memories are created.
The level A ₀ at each position where the running pulse P is output within the distance L is sequentially stored as A(1), A(2), . . . A(400). That is, these steps 102 to 110
is used to store the level within the initial traveling distance L of the track straightening machine in the memory.

When I=N (=400) (step 106), the current I is returned to 0 (step 112).

Next, the arithmetic unit 44 calculates the digital signal A of the front level indicator 18 stored in the memory at address 0 in step 104.
(0) is read out (step 114). The memory means built into the arithmetic unit 44 reads the digital signal A ₀ of the front level indicator 18 at that point in time (step 116), and newly stores the value A ₀ as memory A (0) at address 0 (step 118). ). Then the next running pulse P
After waiting for 1 to become logic 1 (step 120), 1 is added to the above I (step 122). Then I is N
(=400).
124), repeat the above steps 114 to 124. If it is determined in step 124 that I=N (=400), after returning I to 0 (step 112),
Repeat actions 114-124.

In FIG. 4, 46 is a D/A converter, which converts the digital signal A(I) of the pre-leveller 18 output by the arithmetic unit 44 in step 114 of FIG. 5 into an analog signal a(I). . 48 is an analog pen recorder. This recorder 48 includes a pulse motor 52 that winds up the recording paper 50, and this pulse motor 52 rotates in synchronization with the traveling pulse P. In other words, this pulse motor 5
2 rotates by a predetermined angle one step each time the running pulse P becomes logic 1. Since the integrated value of the traveling pulses P is proportional to the traveling distance of the track straightening machine, the amount of winding of the recording paper 50 is also proportional to this traveling distance. The recorder 48 has two pens 54,
56, each pen 54, 56 records the analog signal a(I) which is the output of the D/A converter 46 and the analog output B of the rear level indicator 20 in parallel on the same time axis. Note that the same time axis herein means an axis perpendicular to the feeding direction of the recording paper 50. In the above embodiment, based on the running pulse P, the computing unit 44 stores the output of the front level indicator 18 and reads out the contents of the memory, and on the other hand, based on the same running pulse P, the pulse motor 52 of the recorder 48 is Rotating step by step. Therefore, on the recording paper 50, the levels before and after adjustment are recorded in a step-like manner. However, in the present invention, it is also possible to cause the travel distance detector to generate two types of travel pulses with different pulse intervals, and to rotate the pulse motor 52 by the short-cycle travel pulses.

As described above, this invention sequentially temporarily stores the output of the front level as a digital signal in the memory of the computing unit, and from the time when the track straightener has traveled the distance between the front and rear level, the output is sequentially stored as a digital signal. The output of the front level gauge before the distance between the front and rear level gauges is read out, and the output of the front level gauge and the output of the rear level gauge corresponding to the same orbit position are recorded in parallel on the same time axis. It is something. Therefore, it is possible to easily read the level before and after the leveling at the same track position, and it is possible to easily determine whether the leveling is good or bad.
