Method of inspection of profile of crushed stone ballast base

FIELD: railway transport; permanent way.

SUBSTANCE: invention relates to method of noncontact inspection of profile of ballast base passing square to longitudinal direction of track. Inspection is carried out together with recording of deviation of track in level and in position. Depending on recorded defects as to level (a) and profile of ballast base 13 obtained for said level, amount of crushed stone for lifting track 4 to preset level and uniform ballasting is determined. To find amount of crushed stone required for ballast base 12, recorded profile of ballast base 13 is applied to preset profile of cross section 14.

The invention relates to a method for the contactless inspection of the profile of crushed stone ballast base rail, perpendicular to the longitudinal direction of the path.

From patent US 6058628 known method of registration of the profile of the ballast base in combination with the ballast plow. So you can determine where gravel in excess, in order to use it - if neobhodimosti accumulated in his short time on those sections of the route where it is not enough.

From the article “Rail Engineering International” 2000/3, page 16 known method of measuring the position of a path using electronic measuring carriage EM-SAT, so then recorded in the memory correction values can be passed in spanopoulou machine.

The objective of the proposed invention is a method of the specified type, using which it can be improved ballasting path.

According to the invention this problem is solved by a method of the mentioned type with distinctive characteristics given in claim 1 of the formula.

Thanks to this combination of examination of the profile of the ballast base with the definition of a defective road condition on the level in the distribution of aggregates in the case of a large number of defects at the level to take account associated with this required an increased amount of rubble. Thus the can is to use the measurement position of the path, best way without any additional manipulation, also to determine the amount of gravel required for a uniform ballasting track.

Other benefits and forms of carrying out the invention described in the other claims and represented in the drawings.

The invention is described in more detail below on the basis of the example of execution represented in the drawings.

Figure 1 is a side view of an electronic measuring carriage.

Figure 2 is a registered profile ballast base and overwrite the specified cross-sectional profile of crushed stone ballast grounds contained in the storage device.

Figure 3 is a graphical depiction of the amount of rubble, related to both halves of the path.

4 is a chart of volume for a particular section of the route.

Measuring car 1 presented in figure 1 has a machine frame 2, is made with the possibility of movement on the track 4 with running gears 3. To measure the position of the path in a known manner is provided a laser transmitter 5, performed in combination with a device for measuring distance, and in front of self-propelled travel trolley 6 for education baseline 7. Measuring car 1 is equipped with a drive 8, and the possibility of movement in the working direction 9. In the cab náchod the tsya computing unit 10.

At the beginning of the measured section of the route waypoint cart 6 set ahead at a distance from the measuring car 1 and determine its location relative to the pivot point. Next, the measuring carriage 1 moves in the direction 9 and detects the position of the path relative to the baseline 7 and overwrites the information in the storage device, for further commissioning spelaeogriphacea machine.

At a distance of about 3-4 meters above by 4 set the laser scanning device 11, which measures the distance to the gravel ballast base 12 with a resolution on the corner of 0.25° range ± 50° perpendicular to the longitudinal direction of the path. These data computing unit 10 calculates the profile of the ballast base 13, which can be seen in figure 2, and reflects on the color display. This measured profile of the ballast base 13 impose a given cross-sectional profile 14 (indicated by dash-and-dot line 14), calculate the volume, resulting from the difference between the two charts, profiles, and are in the form of a diagram of the strips 15 (Fig 3 and 4).

In this calculation take into account also accidentally installed the defect level of the path and so that for large defects in the position of the path and because of its higher lifting trebuetsya subsequent process of tamping sleepers way more rubble. This means that a given cross-sectional profile 14 is calculated from the slopes on the error of the provisions of the path and the profile of the ballast base 13, so that the defective position is automatically included in the calculation volume. This leads now, in particular in case of large defects on the roads of great extent, to the fact that these sites can provide gravel purposefully and in sufficient quantities for optimal fixation of the corrected position of the path.

Profile of crushed stone ballast base measured every 2 m, and the corresponding profile of the ballast base 13 according to figure 2 graphically represent and impose on the specified cross-sectional profile 14, which was selected to start working for the corresponding section of the route.

According to figure 3 in parallel for each profile ballast base 13 make up a chart in the form of strips 15 on the middle path 16, and the green band (here marked by a solid line) means the excess of rubble, and the red band (dashed line) indicates the lack of rubble. The height of the bands shows the difference of volume between the profile of the ballast base 13 and a given cross-sectional profile 14. For each sequence of strips 15, presented at figure 3, you can install that on this site Putin left his half of the 17th (above the middle of the road 16) certainly there is an excess of crushed stone, while on the right half of the path 18 (below the middle of the road 16) is visible then a slight deficiency of rubble, a small excess.

In the diagram figure 4 shows the characteristic difference in the amount of rubble. To do this accurately determine necessary to plot the path of a linear weight of crushed stone in tons, accounting for the aforementioned mid-way 16 it is already known whether the gravel on only one half 17; 18. This can accurately be taken into account when dropping gravel, making it possible to explicitly reduce the number of movements of the ballast plow performed during tamping of the track. Extra crushed stone taken away from the path, some time accumulate and dump targeted at those areas where it is needed.

The combination of position measurement path with the registration of the distribution of the rubble has the special advantage that the rubble - as a sort of by-product and no additional manipulation is distributed in an optimal way. In addition to the significant savings it also has the special advantage that, avoiding largely unnecessary movements of the ballast plow through the rubble, it is possible to achieve in the end a uniform ballasting the track.

Alternatively presents exemplary embodiment it is also possible to check the profile of the ballast Foundation in conjunction with the activation spelaeogriphacea machine.
