Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a level recording device for a track straightener that records 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 reason, 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 so. 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 straightening machine that is equipped with a climbing device and a tamping device installed between the rear level gauges and levels the track while repeating running and stopping, a running distance detection device that outputs running pulses every predetermined running distance. a memory means for storing the output of the front level as a digital signal for each of the running pulses, and an output of the front level before the distance between the front and rear levels while calculating the running distance by integrating the running pulses. and a digital printer that records the outputs of the front and rear levels at the same track position together with the travel distance based on the outputs of the rear level and the computer. This is achieved by the characteristic level recording device of the track straightening machine. 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, the reference numeral 10 indicates a front wheel, and the reference numeral 12 indicates a rear wheel, 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 wheels 10, and 20 is a rear level provided between the rear wheels 12. The front and rear level gauges 18 and 20 are provided with left and right small wheels 22, 22a, 22b, 24, 24a, 2, respectively.
It detects the inclination of the axles 26 and 28 connecting the 4b, 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 wheels 24. That is, this traveling pulse P outputs a digital signal of logic 1 every predetermined traveling distance 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 hoisting device 32 moves the right track 16b and the right track 16b.
When using this as a reference, lift each left orbit 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,
Reference numeral 40 denotes an A/D converter that converts the analog signal A indicating the level, which is the output of the pre-level device 18, into a digital signal _A0 indicating the level. Also, 42 is the rear level 2
This is an A/D converter that converts an analog signal B, which is an output level of 0, into a digital signal _B0 . These A/D converters 40 and 42 receive digital signals A ₀ ,
B ₀ is constantly output.

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 number of memories is, for example, 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.
There are 400 memories, and each memory is assigned an address from 0 to 400. The memory means built in the calculator 44 sequentially writes the digital signal A ₀ of the front level indicator 18 into each memory every time the traveling pulse P becomes logic 1, as will be described later, and also writes the digital signal A 0 ( I) are read out sequentially. This calculator 44 also calculates the travel distance X.

The operation of the arithmetic unit 44 will now be explained with reference to FIG. When the device starts first, the steps
Initial conditions are entered at 100. That is, the memory address I and the index n indicating how many times the traveling distance is the distance L are each set to 0, and the number of traveling pulses 400 corresponding to the distance L is input. The memory means built into the arithmetic unit 44 is an A/D
The digital signal _A0 output from the converter 40 is read (step 102) and stored as A(0) in the memory at address 0 (step 104). Next I
=L or not, that is, whether the traveling distance has reached L (step 106), and if I<L, wait until the traveling pulse P becomes logic 1 (step 106).
108), add 1 to I (step 110). By repeating steps 102 to 110, the level A ₀ at each position within the distance L is stored in 400 memories.
are sequentially stored as A(1), A(2), . . . A(400). That is, these steps 102 to 110 are for storing the level within the initial traveling distance L of the track straightening machine in the memory.

When I=L=400 (step 106), the current I is returned to 0 (step 112), and the travel distance X of the track straightener is calculated (step 114), that is, X=d(I+Ln). where d is a coefficient representing the distance traveled while the travel pulse P becomes a logic 1 pulse. The travel distance X indicates a distance calculated based on the position of the front level gauge 18 when the track straightening machine starts traveling. Next, the computing unit 44
is the digital signal of the front level 18 stored in the memory at address 0 in step 104, that is, the front level 1
The digital signal _A0 indicating the level detected by step 8 is read out (step 116). The memory means built into the arithmetic unit 44 reads the digital signal A ₀ from the level indicator 18 at that time (step 118), and sets the value A ₀ to 0.
The address is read into the memory as A(0) (step 120). Then, the computing unit 44 waits for the next running pulse P to become logic 1 (step 122), and then
Add 1 to (step 124). Then I becomes L=
Make sure it has not reached 400 (step
126), repeating the operations of each of the above steps 114 to 126. If it is determined in step 126 that I=L=400, 1 is added to the index n (step 128), I is returned to 0 (step 112), and the operations of steps 114 to 126 are repeated.

In FIG. 4, 46 is a digital printer, and this printer 46 is connected to step 114 in FIG.
The distance X calculated in step 116, the digital signal A(I) of the front level 18 before the distance L read out in step 116, and the digital signal of the rear level 20 output by the A/D converter 42. It is recorded on the recording paper 48 so that B ₀ is written side by side. For example, in Figure 4,
At a position (X = 9.5) 9.5 m away from the start position of the front level indicator 18 in the traveling direction, the level before adjustment was 35.3 mm, but after adjustment it became 36.0. has been done.

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 sent to the printer, and this printer records the output of the front level gauge and the output of the rear level gauge that correspond to the same track position along with the travel distance. It is composed of Therefore, it is possible to easily read the level before and after the leveling at the same track position, and it is easy to determine whether the leveling is good or bad.
