Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
The invention provides a kind of amount of dialling maintenance process of curve track, wherein, the maintenance process of this group of amount comprises:
The actual rotational angle α of S1, experiment curv track, calculates the long L of curve of this curve track according to the actual rotational angle α of this curve track and design radial R;
The long L of curve that S2, basis calculate, this curve track arranges multiple equidistant measuring point, measures the on-the-spot versed sine F of each measuring point

if;
S4, according to on-the-spot versed sine F
realwith design versed sine F
ifshow that the complete of each measuring point dials amount;
S5, amount of dialling each measuring point complete are carried out at least three times and are calculated, wherein, each measuring point has when calculating at least three times the corresponding estimated value reduced successively, thus extrapolate the reality amount of dialling of each measuring point after calculating at least three times, wherein, the differences such as the estimated value sum of all measuring points calculated at least three times reduce.
Like this, after calculating complete group of amount of each measuring point, carry out calculating at least three times and the reality amount of dialling drawing each measuring point after calculating at least three times to the full amount of dialling of each measuring point, thus the curve reducing curve track maintenance significantly dials the amount of moving, the allowable deviation management value making group rear curve versine of curve track and design versed sine worst error meet curve track maintenance specifies, after track lining adjustment being carried out to curve by this actual group of amount, the quality of curve track maintenance can be improved further, and reduce the labour intensity of maintenance personnel.
Preferably, in order to further extrapolate the reality amount of dialling of orbital curve exactly, in the step S5 of of the present invention group of amount maintenance process, five reckonings are carried out to the full amount of dialling of each measuring point, until the estimated value of the part measuring point calculated for the 5th time is zero, the estimated value of part measuring point is minimum even number value 2 or minimum odd number value 1, at this, the numerical tabular that estimated value is even number is only show in Fig. 2, estimated value is that the numerical tabular of odd number does not show, but after repeatedly calculating, the reality amount of dialling of orbital curve can both be drawn exactly, according to this actual amount of dialling, maintenance is carried out to curve track, the smoother degree that curve track keeps good can be made.
In like manner, as mentioned above, the estimated value in step S5 can be all even number or be all odd number, and such as, even number as shown in Figure 2 calculates numerical tabular.
Further, in detailed reckoning process, in even number reckoning process such as shown in Fig. 2, in step s 5, in N (N>=1) secondary reckoning, to the middle part measuring point of curve track from N number of measuring point, estimated value increases, meanwhile, to the final measuring point of curve track from the middle part measuring point of curve track, estimated value reduces.Such as, in first time calculates, the estimated value of first measuring point is even number 2, and from first measuring point to the 9th measuring point, estimated value even number increases gradually, when the 9th measuring point, estimated value is 18, subsequently, to the 18th measuring point from the 10th measuring point, estimated value is reduced to 2 from 18 even numbers, and the estimated value of the measuring point that the 19th measuring point is later is then zero; In like manner, in second time calculates, from second measuring point, the estimated value of second measuring point is even number 2, and to the 8th measuring point, estimated value even number increases to 14, the estimated value of the 9th measuring point and the 10th measuring point is then 14, and to the 17th measuring point from the 11st measuring point, estimated value even number reduces successively.Namely, as can be seen from Figure 2, along with reckoning number of times, such as carry out 5 times and calculate, the minimum even number of estimated value is trapezoidal profile in the both sides of all measuring points.Certainly, in concrete reckoning process, according to concrete reckoning process, the estimated value that each measuring point calculates at every turn correspondingly can be adjusted.
In addition, dialling in the step 3 of amount maintenance process at curve track of the present invention, the average versed sine of curve track is by F
all=F
always/ (L/d) calculates acquisition, and wherein, L represents that the curve of curve track is long, and d represents the spacing between measuring point.The long L of curve of curve track can from formula: L=R α π/180 calculate, such as, as the design radial R=300m of curve track, when actual rotational angle α is measured as 19.02 °, long L=300 × 19.02 of curve of this curve track ° × 3.1416/180=99.59m, thus corresponding equidistant measuring point of counting can be set according to the curve of this curve track is long, such as, when the long L of the curve of curve track is 99.59m, 21 measuring points can be set, as shown in Figure 1, now, the spacing of measuring point is 5m, and chord length is 10m.
In addition, in the step S4 of group amount maintenance process of curve track of the present invention, by the on-the-spot versed sine F of each measuring point
realdeduct design versed sine F
ifpoor to draw the versed sine of each measuring point, the difference of the versed sine of last measuring point difference as this last measuring point is added up, and add up to add that the versed sine difference of this measuring point show that the difference of this measuring point adds up by the difference of last measuring point, then add up the difference of the last measuring point of this measuring point to add half group of this last measuring point half group of amount measuring out this measuring point, and half of each measuring point group of amount is multiplied by the complete group of amount that two draw each measuring point.
Further, poor in order to reduce to dial amount, add up, between half group of amount, once to revise, wherein in the difference of each measuring point, according to the difference of all measuring points add up to draw the accumulative and negative sense of forward difference poor accumulative between difference, meanwhile, make in this is once revised, the correction sum of each measuring point equals this difference, like this, can show that half group of amount and complete the dialling of each measuring point of orbital curve are measured more accurately.
In addition, the reality amount of dialling of each measuring point equals the full estimated value sum dialled amount and calculate at least three times with this measuring point of this measuring point.Namely, in the present invention, each measuring point complete is dialled after amount adds the estimated value that this measuring point repeatedly calculates, be only the actual numerical value carrying out dialling amount of this measuring point, like this, the actual versine of each measuring point just can be made to be+2mm with design versed sine worst error, and the difference of versine on curve between adjacent measuring point is less than or equal to 2mm, make it meet the operation of orbital curve versed sine and check and accept allowable deviation management value regulation, thus curve track can be made accordingly to reach high-level smoother degree.
Below in conjunction with Fig. 1-3, describe the embody rule dialling amount maintenance process of curve track of the present invention in detail, particularly:
Fig. 1 shows the schematic diagram of certain section of curve track.The design radial R=300m of this curve track.
First, in-site measurement is carried out to the actual rotational angle α of this curve track, draws actual rotational angle α=19.02 °, calculate long L=300 × 19.02 of the curve ° × 3.1416/180=99.59m of this curve track according to formula L=R α π/180;
Subsequently, must the general principle of self-contained distance between each measuring point of executing track lining according to existing rope, measure to calculate dialling of this curve more accurately, spacing d between measuring point can be set to 5m (in the curve amount of the dialling operation of reality, for the curve track being less than 100m, spacing between measuring point is generally 5m), therefore, 99.59m is approximately 100m, and 21 measuring points are set on the curve of this 100m length, but, because the physical length of curve is less than 100m, like this, an end points 0 ' of curve track will drop between 20 measuring points and 21 measuring points, make end points 0 ' to the distance b=4.59m of 20 measuring points, to the distance a=0.41m of 21 measuring points, simultaneously, at these curve track two ends and rectilinear orbit transition part place, 0 measuring point is respectively set again, specifically as illustrated in fig. 1 and 2.Therefore, in these 21 measuring points, the spacing d=5m between each measuring point, the chord length between measuring point is 10m.
The on-the-spot versed sine value F of in-site measurement 21 measuring points and two o measuring points
real, and the on-the-spot versed sine value addition of these 23 measuring points is drawn on-the-spot versed sine F
always, as shown in Figure 2, F
always=804.
According to formula F
all=F
always/ (L/d)=804/ (99.59/5)=40.4 ≈ 40mm calculates the average versed sine of this curve, like this, approximate calculation can go out the design versed sine F of each side point
iffor:
F1=F
all÷ 2=40 ÷ 2=20mm;
The design versed sine of f2 to f19 is 40mm;
F20=F
all× (1-(a ÷ 5)
2/ 2)=40 × (1-0.082
2/ 2)=39.8 ≈ 40mm;
F21=F
all× ((b ÷ 5)
2/ 2)=40 × (0.918
2/ 2)=16.8 ≈ 17mm.Specifically see the numerical tabular of Fig. 2.Now, the design versed sine summation of all measuring points is 804.
In each measuring point, on-the-spot versed sine is deducted design versed sine, show that the versed sine of each measuring point is poor, subsequently, the difference of the versed sine of 0 measuring point of starting point difference as this 0 measuring point is added up, and according to the difference of this measuring point add up=difference of last measuring point adds up+difference that the versed sine difference of this measuring point calculates this measuring point adds up, such as, the difference of measuring point 2 adds up as 38+ (-23)=15, the like, the difference calculating each measuring point adds up, after showing that the difference of each measuring point is accumulative, statistics forward difference adds up as+364, adding up reverse poorly adds up as-249, like this, can show that reverse poor accumulative needs-115 could be equal with+364,
Subsequently, according to-115, all measuring points are once revised, as shown in Figure 2, the correction value of 0 measuring point of starting point is set to-1, and increases to the correction value of measuring point 10, reduce from measuring point 11 to the correction value of last measuring point, the correction value summation making all measuring points is-115.
Then, half group of amount of 0 measuring point of starting point is set to 0, thus according to the difference of: half group of amount=last measuring point add up+correction value of half group of amount+last measuring point of last measuring point calculates half group of amount of this measuring point, and further half group of amount is multiplied by 2 and show that the complete of this measuring point dials amount;
Then, as shown in the numerical tabular of Fig. 2, with the form of even number, five reckonings are carried out to the full amount of dialling of each measuring point, in each reckoning, from initial measuring point to middle part measuring point, even number increases, reduce again from the measuring point of middle part subsequently, specifically see the numerical tabular of Fig. 2, thus the differences such as the estimated value sum of all measuring points calculated for these five times are reduced, the estimated value as all measuring points of first time reckoning is 180, second time is 140, third time be the 100, four time is the 60, five time is 20.
Then, the full amount of dialling of each measuring point is added the reality amount of dialling after the reckoning being this measuring point with the estimated value that this measuring point calculates for five times, the reality amount of dialling as measuring point 9 is-252+18+14+10+6+2=-202, it should be noted that at this, negative sign in Fig. 2 numerical tabular represents relative to reference line up or down, or be relative to reference line forward or backwards, only for representing the direction of dialling and measuring.
Finally, according to: versine=on-the-spot versed sine+reality dials amount-(last measuring point is actual dials an amount+rear measuring point actual group of amount)/2, versine as measuring point 9 is 91-202-(-158-148)/2=42, can draw the versine of all measuring points.
As shown in Figure 3, in the numerical tabular shown in Fig. 3, existing rope executes the-252mm that maximum group of the curve drawn amount is measuring point 9 ,+the mm that minimum group of amount is measuring point 12, dials amount minimax difference and reaches 250mm, thus make the reality amount of dialling after calculating larger.In contrast to this, as shown in the numerical tabular of Fig. 2, in the maintenance process of of the present invention group of amount, after the complete group amount of measuring point is repeatedly calculated, maximum group of amount of curve is the-202mm of measuring point 9, minimum group of amount is the+16mm of measuring point 18, dialling amount minimax difference is 186mm, thus reduce the minimax amount of dialling difference, the amount of dialling of curve is made to control in ideal range, versine carries out track lining maintenance to curve track accordingly, curve track can be made to reach high-level smoother degree, improve the maintenance quality of curve.Meanwhile, the method for the present invention also reduces the labour intensity of operating personnel.
