The invention relates to the construction and Ramones position of the path between the reference points relative to the stationary measurement system and improve railway path (Popovic M. C. and other "Mechanical alignment of the railway track. Tutorial on the subject "Travel machines", part 2, St. Petersburg, 1997, pages 5-12).

There is a method of alignment of the railway track, which measure the position of the path relative to reference points in the points of their location, determine the position of the path between the reference points, determine the corresponding values of shifts and/or podemos path on the comparison of the measured and certain provisions of the ways to design and improve railway track in accordance with these values shifts and/or podemos path (the prospectus of the company Plasser& Theurer, presented at the exhibition track machines, Linz (Austria) in September 2000).

Well-known travel machine that contains a frame supported on the undercarriage, a device for alignment of the railway track mounted on the frame and including hoisting and pulling device and United with him measuring device with sensors measuring krivolineynoe path in the plan and/or in the longitudinal profile in relation to the base of the measuring device and/or measuring the elevation of the path level ("Machine lining, tamping, leveling CDF-02", Technical description and operating instructions, the bit-straightening device and United with him measuring device with sensors measuring krivolineynoe path in the plan and/or in the longitudinal profile in relation to the base of the measuring device and/or measuring the elevation of the path level ("Machine lining, tamping, leveling CDF-02", Technical description and operating instructions, M., "Transport", 1995, pp. 68-93).

Known measuring device containing the sensors measure krivolineynoe path in the plan and/or in the longitudinal profile in relation to the base of the measuring device and/or measuring the elevation of the path level ("Machine lining, tamping, leveling CDF-02", Technical description and operating instructions, M., "Transport", 1995, pp. 81-93).

In the known methods the bearing rail tracks create between work (intermediate) base frames of reference (the long chord) in the form of a stretched wire, fishing line, geodetic or optical axis, for example, using a laser beam system (EM-SAT), determine the position of the path between the reference points relative to the artificially created database of reference, measure the actual position relative path reference points in their locations (either manually or by use of mechanical devices), compare the measured position of the path with the project, program comparison results in system alignment the lining, tamping, leveling machines (determine the corresponding values of shifts and/or podemos path by comparing the results and correct the path in accordance with these p>

Since the actual position of the path may differ from the project, then you need to measure the actual position of the path relative to the working rappers in their locations. This work is currently carried out manually or mechanized (using special technical means).

For manual measurements, use a tape measure and templates of various modifications, Reiki, etc. allowing to measure the actual position of the path relative to the frame in a horizontal and/or vertical planes.

There is a technical tool (device) using, for example, special trolley lightweight design, which is equipped with an electronic total station, an inclinometer, a microcontroller device to print the Protocol and memory card data. This tool served by one person. To determine the actual position of the path relative to the marker device is manually set on the label of the point of installation of the device corresponding to the position of the frame, and manually fix the shutter. People serving this device, induces electronic tachymeter on the frame and provides for the measurement of the actual position relative path reference. The actual znakomite, set on a special system EM-SAT, which can be used to generate software job shifts (podemos) paths, elevations for myprivacy systems installed on lining, tamping, leveling machines. The above-described technical means of measuring the actual position relative path reference is quite cumbersome, because it contains a special cart installed on it, expensive equipment, and the use of his labor-intensive, requires precise installation and fixing it relative to a reference point. It required a special person. The specified technical tool allows you to automatically determine the actual position relative path reference in its location.

Information obtained only in the locations of the fiducials, to provide anti-aliasing systems by the method of fixed points and the installation path in the design position in the fixed coordinate system is not enough. For this purpose it is necessary to have information about the actual position of the path between the reference points that are a certain distance (60-80 m).

There are several known methods and devices for setting reference points between the frames: the, and at intermediate points between frames produce a measurement of the actual position relative path stretched wire (fishing line) or geodesic axis; - automated way using, for example, a special system EM-SAT (main machine), creating the optical base reference between frames, and represents a special measuring carriage with two four-wheel bogies, running a receiving unit for laser rays, the device for measuring the elevation of the rail gauge, trip distance, two video cameras and a monitor for positioning the measuring axis relative to the frame, industrial computer with appropriate software, printer, and satellite truck with mounted therein a laser transmitter that generates the optical axis.

The measurement process in the system EM-SAT is carried out cyclically. Satellite laser move to the next frame and stop at the distance of several meters behind this marker. The laser with the optical sight set with respect to the receiver main machine. The main machine with the measuring axis is exactly on the mark, indicated by the colored paint on the sole of the rail dodowa rail and wheel measuring axis. During the measurement of travel measured actual position relative path of the laser beam every 20 meters and remember. After reaching the next rapper calculate the magnitude of the shift and hoisting this part of the path and throw them on the monitor and the printer. At this time the satellite has already moved to the next marker and laser establish for the next measuring operation. The system EM-SAT allows you to measure long uneven path in plan and longitudinal profile through the use of long laser notochord.

The above-mentioned methods and measurement devices have the following disadvantages.

Thus, the use of wire or fishing line, which are not rigid and fixed, manual measurement, introduces errors in the measurement results. In addition, the use of the measuring lines, the need for constant monitoring of vertical and horizontal rails, slats and other measuring equipment requires engagement to obtain the necessary information from several people, and each measurement is superimposed impact of a large number of random and non-random factors which are very difficult to Vilnia paths are relative to the wire or fishing line using manual measuring very problematic and time consuming. More accurately you can determine the position of the path between the frames using surveying instruments, but this method is also time consuming.

Less time consuming is the way of measuring the actual position of the path between frames using a special system EM-SAT. However, this method also certain disadvantages. Time-consuming in this way is an operation for setting up the laser system at each permutation of the satellite. The accuracy of the position measurement path in this way can influence the uncertainty in the movement of trains on the adjacent path. The maximum length of the laser chord can be 250 meters only on straight sections of road without fracture of the longitudinal profile. Maximum system performance EM-SAT is on straight parts of the road 2.5 km/h. Performance drops sharply when working on the curves of the track sections and is 1.1 km/hour, as on curves of small radius the length of the laser chord should be significantly less. The length of the laser chord on a curve plot of the path depends on its radius and can be from 60 m and more, that is a curve plot of the path requires more permutations laser chord than on a straight section of road.

Thus, for obliviouse type to ensure the installation path in the design position in the fixed coordinate system into an existing track car (the closest analogue), in an existing device for alignment the way you want to use: - the device using a special truck (and support person), which provides the definition of the actual situation the way at places of business benchmarks, and information about the project location path; - system EM-SAT (special measuring car) with the satellite truck.

The cost of the above equipment is very high, the performance curves of the track sections is sharply reduced and servicing this equipment requires the involvement of relevant staff. All this reduces the effectiveness of the known method of alignment the device for alignment of road and track machine implementing this method of alignment the way.

The technical result of the invention is to improve the quality of the alignment path with the software installed in the specified (design) position in the fixed coordinate system, improving the performance of the work on his path due to the exclusion of the personnel necessary for the maintenance of a measuring carriage and a special truck.

To achieve this, the technical result in the way that the alignment of the railway track, which consists in the fact that the first cast out, determine the corresponding values of shifts and/or podemos path on the comparison of the measured and certain provisions of the ways to design and improve railway track in accordance with these values shifts and/or podemos path, determine the position of the path between frames using roaming along the path measuring device by measuring krivolineynoe path in the plan and/or in the longitudinal profile in relation to the base of the measuring device and/or measuring the elevation of the path level and calculating the position of the path between the reference points in the fixed coordinate system taking into account the mentioned measurement krivolineynoe path and/or measuring the elevation of the path level.
