Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to the relaxation and modification of a multiple titan tamper used in the work of modifying the transition curve and vertical curve of a trajectory.
This invention relates to a vertical curve correction control device.

A multiple titanpa is being considered that can not only correct the amount of cant in the transition curve portion of the trajectory, but also correct the vertical curve of the trajectory.

FIG. 1 is a diagram showing the principle of the system. Reference numeral 1 indicates the rail of the track, 2 the front reference section, 3 the height detection section, and 4 the rear reference section. These run while keeping a predetermined distance from each other. The front reference section 2 can be configured, for example, as a light source, and the rear reference section 4 can be configured as a light receiving section. In this case, a light beam connecting both the reference sections 2 and 4 becomes the reference line 5. The height detection section 3 is composed of, for example, a slit, and since the light beam passes through this slit, these reference sections 2,
4. Detects that the height detection section 3 is located on the reference line 5. Reference numeral 6 denotes a tamping device, and numeral 7 denotes a lifting device. When the elevation detecting section 3 is deviated below the reference line, the lifting device 7 lifts the track, and at the same time, the tamping device 6 tames the lower part of the sleeper. Note that the height of the height detection section 3 can be moved up and down by, for example, a hydraulic mechanism. Therefore, if the height detection section 3 is set below the reference line 5, the trajectory 1 is lifted and corrected so that the detection section 3 is placed above the reference line 5.

Note that the devices shown in FIG. 1 are provided in pairs on the left and right corresponding to the left and right orbits.

Reference numeral 8 denotes a level detector consisting of a pendulum or the like, which detects the height difference between the left and right rails 1.

First, correction of the transition curve will be explained. FIG. 2 is a diagram showing the relationship between the transition curve and the cant amount c, where c', d, and e indicate the ranges of the straight line, transition curve, and circular curve, respectively. Within the circular curve e, the cant amount c
is constant, and in transition curve d, the cant amount gradually increases or decreases from zero to c. That is, the level detector 8 detects the height difference (cant amount) between the left and right rails with respect to the running distance x from the entrance B of the transition curve d, using the inner rail as a reference, and the level detector 8
The tamping device 6 then lifts the outer rail by a cant amount c shown in FIG. This transition curve d
The relationship between the cant amount c and the traveling distance x of the level detection unit 8 within the range is defined as a transitional curve function Y(x). Various functions have been proposed as this transitional curve function Y(x), and there are cases in which the cant amount increases from a straight line to a circular curve, and cases in which the cant amount gradually decreases from a circular curve to a straight line. For example, in the case of linear increase as shown by the solid line in Figure 2, let L be the length of the transition curve,
It will look like this:

Y(x)=x・c/L...(1) In addition, in the case of linear decrease, Y(x)=(1-x/L)c...(2). In addition, in the case of increasing sine as shown by the broken line in Figure 2, Y(x)=(1-cos x/L・π)c/2...(3) In the case of decreasing sine, Y(x)={1- (1-cos x/L・π)/2}c
...(4) becomes. Furthermore, in the case of quadratic parabolic increasing, Y(x)=(2x/L) ²・c/2...(5) In the case of quadratic parabolic decreasing, Y(X)={1-(2x/L) ² / 2}c...(6).

Next, correction of the vertical curve will be explained.

FIG. 3 is an explanatory diagram of a method for correcting the entrance section when the vertical curve is a concave curve. In this figure, the distance that the front reference part 2 enters into the vertical curve with the vertical curve entrance B as a reference is defined as the traveling distance x. When the front reference part 2 passes through the entrance B, the front reference part 2 rises along a vertical curve. The amount of increase υ is R as the vertical curve radius R
If we assume that >>x, then υ=x ² /2R. Therefore, it is necessary to change the height of the front reference section 2 or the detection section 3 as x increases. The expression representing the necessary height correction amount for x is called the vertical curve function y ₁ (x). Since this function y ₁ (x) is detailed in Japanese Patent Application No. 56-36524 filed by the same applicant, it will be briefly explained here.

This vertical curve function y ₁ (x) can be divided into four cases depending on whether the vertical curve is a concave curve or a convex curve, and whether it is on the entrance side or the exit side.

First, in the case of the entrance side of the concave curve (Fig. 3), the situation is as follows. Since only the front reference part 2 rises between 0<x<a, if this continues, the trajectory will be raised so that the detection part 3 will rise. Therefore, the front reference part 2 is lowered by υ=x ² /2R, or the detection part 3 is raised by υ'=b/a+b·x ² /2R. Below, when moving the detection section 3 up and down, the amount of correction of the front reference section 2 -
Since it is sufficient to multiply b/a+b, the vertical curve function y ₁ (x) of the front reference portion 2 will be explained.

Since the detection part 3 itself rises between a<x<a+b, the front reference part 2 must be lowered by an amount corresponding to the rise (x-a) ² /2R. That is, the height of the front reference portion 2 must ultimately be lowered by x ² /2R-a+b/b·(x-a) ² /2R.

From the above, the vertical curve function y ₁ at the entrance of the concave curve is as follows.

Next, in the case of a convex curved entrance, since it is just vertically symmetrical to the case of the concave curved entrance, the sign of equation (7) can be reversed. That is, y ₁ = −y _o ...(8) At the exit of the concave curve, the minimum value of equation (7), i.e. x = a +
From the value of y _o at the time of b y ₁ (a+b)=-a(a+b)/2R≡y _n , y _o increases to zero through the reverse process of equation (7). That is, y ₁ = y _n −y _o ……(9) Similarly, in the case of a convex curve exit, by reversing the sign of equation (9), y ₁ = y _o −y _n ……(10).

It is sufficient to appropriately determine a correction system and correct the trajectory so as to match the above equations (7) to (10).

As described above, the multiple titan tamper determines the amount of cant correction for the transition curve and the amount of height correction of the detection unit 3 for the vertical curve. However, in the conventional device, various set values must be obtained using calculations, charts, etc. in accordance with the trajectory, which has resulted in a problem of low work efficiency. Furthermore, it is difficult to modify the transition curve and the vertical curve at the same time because the work becomes complicated.

Furthermore, in actual work, the multiple tamper needs to not only move forward, but also retreat from time to time for positioning and re-adjustment. Conventional devices calculate the travel distance by integrating the travel pulses output in response to wheel rotation, and when reversing, the generation of travel pulses is stopped until the vehicle returns to the reverse start position, which is a tedious task. This accumulation of mileage was likely to be inaccurate. For this reason, there was also the disadvantage that the accuracy of alignment of the trajectory was reduced.

This invention was made in view of these circumstances, and is a multiple titan that can simultaneously or selectively correct not only transitional curves but also vertical curves, and that can also improve work efficiency and straightening accuracy. The first object of the present invention is to provide a relaxation/vertical curve correction control device for a motor vehicle.

In order to achieve this object, the present invention includes front and rear reference parts and a detection part that run on a track at predetermined intervals, and makes the deviation of the detection part from the reference line connecting the front and rear reference parts to zero. The vertical curve of the track is corrected so that the vertical curve of the track is corrected, while the height difference between the left and right tracks is detected by a level detector and the transition curve of the track is corrected. A distance detector that outputs a signal, a memory that stores calculation programs for multiple vertical curve functions and multiple transitional curve functions, a selection switch that selects one of the functions, a vertical curve radius setter, and front/rear Equipped with an interval setting device for setting the distance between the reference section and the detection section, a cant setting device for setting the constant cant amount of the circular curve, a transition curve length setting device, a distance conversion coefficient setting device, and a digital calculation device. , the digital calculation device performs a predetermined calculation according to the calculation program selected by the selection switch based on the setting values of the setting devices and the output of the distance detector, and calculates a correction cant for determining the height difference between the left and right trajectories. and a height correction signal indicating the height correction amount of the front/back reference section or the detection section.

On the other hand, in an actual track, there are cases where the track is a compound curve in which two circular curves are continuous, and where the amount of track settlement when a vehicle load is applied to the track changes depending on the ground condition. In these cases, conventional devices have a problem in that work efficiency and accuracy are reduced.

A second object of the present invention is to provide a relaxation/vertical curve correction control device that can significantly improve work efficiency and accuracy even in such a case.

In order to achieve this objective, the present invention adds a second cant setting device for setting the manual correction cant amount and an elevation correction setting device for setting the amount of elevation correction, and sets other setting devices other than these two setting devices. A predetermined calculation is performed by a digital calculation device according to a calculation program selected based on the value and the output of the distance detector, and the corrected cant amount and height correction amount obtained as a result of this calculation are added to the manually corrected cant amount and the corrected height amount, respectively. By adding the height correction amount, the corrected cant amount and the total height correction amount are determined.

In actual work, the height of the detector 3 and the height of the reference parts 2 and 4 are determined manually based on various conditions using calculation charts and calculations, and the cant amount and height correction signal are manually determined. You will need to enter it in

A third object of the present invention is to provide a relaxation/vertical curve correction control device that can manually set the amount of cant correction and the amount of height correction.

To achieve this object of the invention, the memory further stores a manual correction program, the selection switch also enables selection of this manual correction program, and in the case of manual correction, the arithmetic unit operates the manual correction program. The manual correction cant amount set by the second cant setting device based on the above is output as the correction cant amount, and the height correction amount set in the height correction setting device is output as the total height correction amount. .

The present invention will be described in detail below based on the illustrated embodiments.

Reference numeral 36 denotes a transition curve selection switch, which selects S ₀ in the case of manual correction, and selects S ₁ -S ₄ in the case of automatic correction by the method corresponding to equations (1) to (4) above. When any one of S ₁ -S ₄ is selected, the corresponding signal S ₁ -S ₄ changes from logic 0 to logic 1.

Select each. When one of S' ₁ to S' ₄ is selected, the corresponding signal S' ₁ to S' ₄ changes from logic 0 to logic 1.
Changes to

38A is a vertical curve correction end detection unit of the arithmetic unit 32, which outputs a stop signal _SP1 of logic 1 when the rear reference unit 4 passes through the entrance or exit of the vertical curve, that is, when x=a+b; This signal SP ₁ is inverted by an inverter 39 and is input to an OR circuit 41 together with a signal SPO which is the output of the transition curve correction end detection section 38 . The output of this OR circuit 41 is sent to the gate circuit 16. 40A is a lamp that indicates the completion of vertical curve correction.

Next, the operation of this embodiment will be explained. In FIG. 5, when the power is turned on, the arithmetic unit 32 sequentially reads programs from the memory 34 and first determines in step 80 whether to modify the transitional curve or the vertical curve. Which one to select is input using a switch (not shown). If you want to modify the transition curve, use the subroutine
Go to SUB-A, and if the vertical curve is to be corrected, go to subroutine SUB-B.

First, the transition curve SUB-A will be explained based on FIG. In step 100, if all of the outputs S ₁ to _{S 4} of the transition curve selection switch 36 are logic 0, it is determined that the switch 36 has selected manual correction S ₀ , and if any of the outputs S ₁ to _{S 4} is If one of them is logical 1, it is determined that automatic correction is required.

At the time of automatic correction, set values L, k, c, c _H are read from the setters 24 to 27 into the arithmetic unit 32 (step 102). In the case of a unicentric curve, and the first of a compound curve
In the case of correction up to a circular curve, the second cant setter 27 sets the manual cant amount C _H to zero.
Also, the cant setting device 26 has a cant amount c of the circular curve e.
Set.

The arithmetic unit 32 determines which of the equations (1) to (4) is selected from the signals S ₁ to S ₄ output by the selection switch 36 (steps 104 to 108). In other words, if S ₁ = 1, equation (1) for linear increase is changed to S ₂ = 1
If so, then equation (2) of linear gradual decline is selected, and similarly, if S ₃ =1, equation (3) is selected, and if S ₄ =1, equation (4) is selected. If S ₁ = 1, the mileage x from equation (11) above
is calculated (step 110), and the cant amount _Y1 at the travel distance x is calculated by calculating equation (1) (step 112). The arithmetic unit 32 then calculates the corrected cant amount Y ₂
is calculated from Y ₂ = Y ₁ +c _H (step 114). Also, the calculation device 32
The set cant amount c _n is calculated from c _n =c + c _o (step 116). Note that in the case of a single-centered curve or the first circular curve of a compound-centered curve, c _H = 0, so the corrected cant amount Y ₂ is calculated by calculating the set cant amount Y ₁ in equation (1). The quantity c _n is equal to the cant quantity c=c _E1 of the circular curve. When S ₁ = 1, it is a linear increase, so the cant amount at the exit E of the transition curve is Y ₁ (L)
is equal to the cant amount c (=c _E1 ) of the circular curve. The calculation device 32 outputs the corrected cant amount Y ₂ and the set cant amount c _n at every predetermined cycle set by the built-in clock until Y ₁ (x) becomes equal to c (=c _E1 ) (step 118). When Y ₁ = c (= c _E1 ), z ₁ is applied to the z ₁ terminal.
=1 (step 120).

In the case of linear decrease (s ₂ =1), the step 112
In place of equation (1), equation (2) is calculated in step 112a. In this case, since the transition curve d enters the straight line c, the cant amount Y ₁ (x) becomes 0, so the exit E of the transition curve d is determined (step 118a),
At that time, output z ₂ = 1 to the z ₂ terminal (step
120a). Similarly, in the case of sine multiplication (s ₃ = 1) and sine multiplication (s ₄ = 1), calculations of equations (3) and (4) are performed in place of step 112, respectively.
112b, 112c), step transition curve exit 118,
Similar to step 118a, the determination is made at steps 11b and 118c, and z ₁ =1 and z ₂ =1 are output, respectively (steps 120b and 118c).
120c). That is, z ₁ goes from 0 to 1 at the end of the increase,
z ₂ changes from 0 to 1 at the end of the gradual decrease.

In the case of a compound curve, at the exit of the first circular curve, that is, the entrance to the transition curve between the two circular curves,
While changing the set value of the cant setting device 26 from the cant amount c _E1 of the first circular curve to the cant value c _E2 of the second circular curve, the second cant setting device 27 changes the cant amount of the first circular curve. c Set _E1 . As a result, the corrected cant amount Y ₁ is determined in step 114 as the sum of the two set values c _E1 and c _E2 . At this time, the counter 18 is returned to zero by the reset button 20.

On the other hand, if it is determined in step 100 that manual correction is required because s ₁ to _{s 4} are all 1, the arithmetic unit 32 reads a manual correction program from the memory 34, and by this program, the second cant setting device 27 is first
Read the manual correction cant amount C _H set in . Then, the arithmetic unit 32 outputs this manually corrected cant amount c _H as a corrected cant amount Y ₂ .

As described above, the calculation device 32 calculates the corrected cant amount Y ₂ ,
The set cant amount c _n and signals z ₁ and z ₂ are output. While the corrected cant amount Y ₂ is displayed on the display 42,
a height control device 44 that controls the height of the detector 3;
sent to. This height control device 44 is constituted by, for example, a hydraulic mechanism, and moves the height of the detection section 3 of the outer rail to a height corresponding to the corrected cant amount _Y2 . The tamping device 6 shown in FIG. 1 corrects the downward deflection of the sleeper, while the lifting device 7 moves the outer rail up and down so that the detection part 3 is on the reference line 5, and corrects the amount of cant of the outer rail. Cant amount
Make Y ₂ . Further, the set cant amount c _n is displayed on the display 46.

Further, the correction end detection unit 38 detects that one of s ₁ to s ₄ is 1.
In the case of automatic correction, the completion of correction of the transition curve is determined based on the signals z ₁ and z ₂ . i.e. s ₁ , s ₂
When one of the logic 1 signals increases to 1, the logic 1 signal is sent to the gate circuit 50a via the OR circuit 48a.
Furthermore, when either s ₂ or s ₄ is decreasing to 1, the logic 1 signal is sent to the gate circuit 50b via the OR circuit 48b. Gate circuit 50
a and 50b are respectively output by the arithmetic unit 32.
When z ₁ and z ₂ are logic 1, the OR circuits 48a and 4 are opened.
The output of 8b is led to the OR circuit 52. Therefore, when z ₁ or z ₂ becomes logic during automatic correction, the OR circuit 52 outputs logic 1, and this output lights up the automatic correction completion lamp 40 . Also, this OR circuit 52
The output is inverted by the inverter 54 and becomes the stop signal SPO. With this stop signal SPO,
The gate circuit 16 cuts off the input of the pulse _p1 and the reversal signal R to the counter 18, and the cant correction work for one transition curve is completed.

In this embodiment, four calculation programs for linear increase/decrease and sine increase/decrease are stored in the memory 34,
Although any one of them can be selected, it is of course possible to store the arithmetic programs for the quadratic parabolic increase/decrease of equations (5) and (6) in the memory and make these also selectable.

In addition, this embodiment is provided with a second cant setting device 27, so it can be applied to the case of compound curves, and the memory 34 also contains a manual correction program (step
122, 124) are also stored, manual correction becomes possible, but it is clear that the intended purpose of the present invention can be achieved even if these second cant setter 27 and manual correction program are omitted. .

Next, in FIG. 5, when it is determined that the vertical curve is to be corrected (step 80), the process goes to SUB-B shown in FIG.

First, in step 200, if all of the outputs S' ₁ to S' ₄ of the vertical curve selection switch 36A are logic 0, it is determined that the switch 36A has selected manual correction, and the outputs S' ₁ to S'' If any one of ₄ is logical 1, it is judged as automatic correction.

At the time of automatic correction, set values R, k, a, and b are read from the setters 28, 25, and 29 into the arithmetic unit 32 (step 202). The height correction amount H determined based on the ground condition etc. is set by the height correction setting device 30.

The arithmetic unit 32 determines which of the equations (7) to (10) is selected from the signals S' ₁ to S' ₄ output by the selection switch 36A (steps 204 to 208).
In other words, if S′ ₁ = 1, the formula for the concave curve entrance can be written as S′ ₂
If = 1, equation (8) for the entrance of the convex curve can be written as follows.
When S′ ₃ =1, equation (9) is selected, and when S′ ₄ =1, equation (10) is selected. If S' ₁ =1, the arithmetic unit 32 reads the number of running pulses N and the height correction amount H (step 210), and calculates the running distance x from equation (5) (step 212). The counter 18 and the arithmetic unit 32 are reset by the reset button 20 when the front reference section 2 comes to the entrance or exit of a vertical curve. Next, the calculation device 32 sequentially calculates the elevation correction function y ₁ for the traveling distance x when S' ₁ = 1 according to equation (7) (step 214), and also calculates the height correction function y 1 for the traveling distance
Calculate the sum y ₂ of y ₁ with the height correction value H, that is, y ₂ = y ₁ + H (step 216), and calculate the function at a predetermined period.
Output y ₁ and y ₂ . These functions y ₁ and y ₂ are calculated at predetermined intervals according to changes in the traveling distance x, where y ₁ represents the normal height correction amount, and y ₂ represents the correction amount when ground conditions and the like are taken into consideration. The calculation device 32 calculates the mileage x=
Perform the above calculations until a + b (step
218), outputs a stop signal SP1 with z ₁ =1 to the terminal 38a when x=a+b (step 220). Since the gate circuit 16 blocks the running pulse _P1 and the reverse rotation signal R using the stop signal SP1, the running distance x does not change thereafter. That is, after x=a+b, the front and rear reference parts 2, 4 and the detection part 3 move on the arc of the vertical curve radius R, so the height correction amount y ₁ is the minimum value y _n ((9), (10 ) becomes constant.

At the concave curve exit, the selection switch 36A is S′ ₃ =1
The counter 18 is reset to zero by the reset button 20. The calculation device 32 sequentially performs the calculations shown in FIG. 7, but compared to the case of the concave curve entrance, step 214 is a step for calculating equation (9).
It just changed to 214c.

Also, in the case of S' ₂ =1 and S' ₄ =1, the calculations of equations (8) and (10) are simply performed in steps 214b and 214d, respectively, so a description thereof will be omitted.

On the other hand, if manual correction is determined in step 200 since S' ₁ to S' ₄ are all 1, the arithmetic unit 32 reads a manual correction program from the memory 34;
With this program, first the height correction setting device 30
Read the height correction amount H set in (step
222). Then, the arithmetic unit 32 outputs this height correction amount H as a total height correction amount _y2 .

As described above, the calculation device 32 outputs the height correction amount y ₁ and the total height correction amount y ₂ . The total height correction amount y ₂ is displayed on the display 42A, while the front reference portion 2
is sent to a height control device 44A that controls the height of the . The tamping device 6 and the lifting device 7 shown in FIG. Further, the correction amount y ₁ is displayed on the display 46A. Note that when changing the height of the detection section 3 instead of the front reference section 2 by automatic correction, the correction amount of the detection section 3 is calculated by multiplying the correction amounts y ₁ and y ₂ by -b/a+b as described above. It is clear that the quantity should be used.

In the embodiments described above, the transition curve and the vertical curve are modified separately. However, it is also possible to modify both curves simultaneously.

FIG. 8 is a flowchart showing an example of such a case. In this embodiment, each time the vehicle travels a predetermined short distance, the calculations of SUB-A and SUB-B are performed as shown in FIGS. demand. That is, for the outer rail, the sum Y of the corrected cant amount Y ₂ for the transitional curve and the total height correction amount y ₂ for the vertical curve is calculated. This sum Y is the amount of correction required for the outside rail. Also, for the inner rail, the total height correction amount for the vertical curve
y ₂ is the amount of correction required. The tamping device ₆ ,
Corrected by the lifting device 7. The above operation is repeated every time the vehicle travels a short predetermined distance until the travel distance x reaches a predetermined amount _X0 (step 84).

According to this embodiment, the transition curve and the vertical curve can be corrected at the same time, so that work efficiency is significantly improved.

As described above, this invention stores calculation programs corresponding to various transitional curve functions and vertical curve functions in advance in a memory, and calculates the corrected cant amount and height corrected amount according to the program selected by the selection switch. With this configuration, it is possible to determine the corrected cant amount corresponding to the travel distance and the height correction amount corresponding to the travel distance without using calculation charts or calculating the cant amount increasing/decreasing magnification. The efficiency of straightening work is significantly improved.
In addition, multiple spiral curve functions and vertical curve functions can be selected arbitrarily, so the optimal spiral curve function and vertical curve function for trajectory correction can be freely changed according to various conditions. There is no need to prepare multiple types of devices, and it is suitable for downsizing. Furthermore, since the mileage is determined by whether the wheels are running in the forward or reverse direction, there is no need to record the start position of backward movement or stop the generation of driving pulses when reversing.
The net travel distance can be calculated accurately, further improving the accuracy of trajectory alignment. Furthermore, since it uses a digital arithmetic unit, it is highly adaptable to changes in specifications, and can be handled simply by changing the software.

In addition, a second cant setting device for setting the manually corrected cant amount c _H is provided, and the calculation device outputs the sum of the calculation result Y ₁ of the transition curve function and this manually corrected cant amount c _H as the corrected cant amount Y ₂ . With this configuration, even in the case of a compound curve, the trajectory adjustment work can be carried out easily and efficiently.

Further, an elevation correction setting device for setting the elevation correction amount H is provided, and the arithmetic unit is configured to output the sum of the vertical curve function calculation result y ₁ and this elevation correction amount H as the total height correction amount y ₂ . For example, in consideration of the state of the ground, the track can be adjusted so that it is raised in advance by a height corresponding to the subsidence of the track when the vehicle is running.

Furthermore, if a manual correction program is stored in the memory and the selection switch is configured to select manual correction, manual correction can also be carried out according to work conditions, and the versatility of the apparatus is further increased.
