Group of inventions relates to the construction and repair of railway tracks, in particular to the technology of the alignment of the railway track, and can be used in preventive behavior, and also for alignment during the repair works, when you finish way before commissioning after the production of major track work.

Known widely used in the production method of the alignment of railway track, including the measurement and comparison of distances in the control section after a specified interval, for example 100 m, between the axes straighten and parallel road with the design situation (from plots Rehovot). Next, perform the calculation of the shift and hoisting paths in accordance with the obtained difference and the subsequent formulation of the way in the design position. As a means of measurement technology used rail leveling (Transport construction, 1/2012, pp. 23-26).

This technology has significant drawbacks associated with the fact that since the survey until the beginning of the ongoing work it takes several months or even years. During this time, as a result of dynamic loads on the way, Rehovot when carrying out planned preventative maintenance works and the influence of other factors the adjacent track to which you are linking, shifting from single�th position (from the survey) on an undefined value. Due to this design the distance between the axes also change. This causes when bearing the irregularities in plan and elevation, which are copied from the neighboring path. In addition, discrete measurements at 100 m does not allow to unambiguously determine the position of the way throughout the 100 m of the site, which also provides a staging in the design position with the required accuracy.

A known system for controlling the bearing of railway track containing a road machine, a frame which rests on the carriage, and mounted on the frame device for the alignment of railway track, including lifting and straightening device with the control unit and the measuring cart, and determining the position of the axis of the path. The system also includes a computing unit, connected to the memory block and the block information display (patent RF №2454498, EV 29/04). The known system comprises a mobile reference station, satellite positioning system, the tilt angle sensor connected to the computing unit that is connected to the output of the receiver of the satellite positioning system and device for determining the spatial position of the measuring carriage. Device for determination of the spatial position of the measuring trolley is placed under the frame of track machines�. In the block of memory contains a electronic model of the project the position of the path in three-dimensional spatial coordinate system. The system is based on determining the spatial displacement of the measuring bogie relative to the satellite antenna. At each time point calculation unit calculates the offset of the current position of the path in plan and profile with respect to the project. Before operating the system, in a memory unit of the computing unit recorded the original data - electronic model of the project the provisions of the road. Refined coordinates produced jointly by the receiver and the reference station, and indicate the location of the phase center of the antenna located on the roof of the track machine. To determine the spatial displacement vector measurement of the trolley with respect to an antenna used for the measurements, angular measurements and distances from the phase center of the antenna to the device for determining the spatial position (displacement) measuring trucks, as well as indications of displacement sensors measuring truck regarding track machine included in the device for determining the spatial position of the measuring bogie relative to the phase center of the satellite antenna positioning system. In addition, we use data on the size of the roll, which comes in the transmitter�block from the tilt angle sensor. Data from the satellite positioning system, the tilt angle sensor and the device for determining the spatial position of the measuring cart is input to the computing unit, which based on these data, calculates the current position of the path and compares it with the design position.

It is also known similar technical solution (patent RF No. 112209, EU 35/ 00, prototype), which describes track machines, containing on-Board computer, based on the running of the trolley frame is equipped with a liner-straightening equipment and control and measuring system, placed under the frame and principle of operation of this device. The specified control measuring system includes a measuring cart containing a movable contact rails leveling road base, and measuring base, rigidly mounted in the bottom bracket track machine in a plane perpendicular to the direction of movement of the track machine. The reference point of the specified measuring base is provided with a linear encoder, mounted with the possibility of measuring them changing the position of the center of the base of the measuring bogie relative to the gauge length, in height and in plan. Satellite antenna rigidly mounted in the upper track machine at a fixed height relative consideration�but measuring base measuring truck. The phase center of the satellite antenna is on the vertical axis passing through the center of the moveable base measuring trucks, in the initial state. The outputs of the sensors linear displacement center of the movable base measuring truck related, on-Board computer.

As sensors linear displacement of the moveable base of the measuring bogie relative to the phase center of the satellite antenna in this technical solution is used, in particular, installed a certain way along the gauge length laser rangefinders or electromagnetic linear encoder.

The common drawback described above technical solutions should include the structural complexity of the used measuring system and, as a consequence, insufficient accuracy of measurements and, accordingly, insufficient accuracy of statement of the way in the design position. These shortcomings have significant impact on the operation of the device for dynamic loads. The mobility track machine determines the complexity of synchronization in real time of three related measuring systems with different inertial characteristics of a satellite positioning system, the systems determine the spatial position of the measuring trolley and systems� reduction of coordinates on the axis of the path (inclinometer).

The task of the group of inventions is to expand the Arsenal of technical means intended for the alignment of the railway track.

The technical result of the group of inventions is to provide a device and method for the alignment of the railway track with the organization of measurements of the current spatial position of this path is relatively selected as the measuring base adjacent the railway track (the nearest rail) with known spatial coordinates. Simplification, on this basis, a device for track surfacing rail journey ensuring high measurement accuracy and, consequently, improving the accuracy of the installation straighten the railroad tracks in the specified (design) position, and the simplification of technology and increase productivity when performing this type of work.

Said technical result is achieved by that in a device for straightening of railway track containing based on the running truck frame track machine, equipped with a liner-straightening equipment, onboard computer, device definition distance traveled in contact with the rails measuring a cart containing a movable base, the sensor spatial position of the measuring truck, the tilt angle sensor track machine, you�odes of these sensors and devices for determining the distance traveled is related to the corresponding inputs on-Board computer, according to the invention, the sensor spatial position of the measuring trolley is installed on the specified moving base capable of measuring the spatial position of the center of the measuring trolley in plan and in profile in relation to the measuring base, which is used adjacent to this railway track (rail) with known spatial coordinates and horizontal and vertical position relative to the leveling path.

Mainly as a sensor spatial position of the measuring bogie, the device includes a laser rangefinder with inclinometer forced spatial orientation on a support of the measuring base.

In addition, as the sensor spatial position of the measuring bogie, the device may include a laser scanner with a given scan angle.

The claimed technical result is also achieved in that the sensor spatial position of the measuring trolley attached to rigidly associated with the specified center of the movable base of the external guide element mounted at an angle of 90 degrees relative to the direction of motion, while the other end of the guide element interacts (slides) with the head rail adjacent railway track, which is the op�world measuring base.

Primarily to determine the distance device according to the invention, includes installed on the rooftop track machine satellite dish and satellite receiver connected via wireless communication with base (referencename) stations, thus the output of the satellite receiver to the appropriate input of the onboard computer.

In order to determine the distance the device can also be used odometer.

According to the invention a method of straightening of railway track using the on-Board computer installed on the track (leveling) machine, characterized by the fact that

- before you start leveling the work carried out measuring the spatial coordinates of one of the threads neighbouring leveling railway track, which is taken for measuring base, specify (specify) design parameters (distance 1 between the axis straighten all the way and measuring base, the angles β, determining the position in the profile (height) straighten all paths relative to the specified gauge length) straighten all the way in plan and in profile on the specified gauge length,

- the resulting design distance 1 plan between the axis straighten all the way and measuring base, the angles β, determining the position in the profile (height) straighten all the way Rel�specified relative measuring base, and the position of the measuring base record in the onboard computer track machine,

- in the course of performing leveling works measure the position (distance 1) and the profile (angle β) of the center of the moveable base measuring trolley track machine on the specified gauge length,

- the current measured value (distance 1, angle β) compared to their design values,

- obtained difference to produce a control signal which serves to liner-straightening device.

The measurement of the spatial position of the measuring trolley track machine in plan and profile on the specified gauge length, is carried out using a results-oriented reference measuring base laser rangefinder with inclinometer, mounted on a rigidly connected to the center of the moveable base of the remote, the guide element is mounted at an angle of 90 degrees relative to the direction of motion, while the other end of the guiding element (slides) interacts with the rail head adjacent the railway track.

The invention consists in the fact that in this technical solution is the control of changes of spatial position (linear and angular) of the center of the measuring trolley, which determines the position severaltimes way on the external, stationary, measuring base, with known spatial coordinates. The spatial position of the specified measuring truck at the track machine movement in a given path is compared with a predetermined design position of the path, on the basis of the received data control signals lifting and straightening equipment.

The drawing schematically shows a General view of the device for the alignment of the railway track according to the invention, in a preferential implementation.

A device for alignment of a railway track comprises a frame 1 track machine based on rails 2 running 3 trucks. On a frame 1 mounted liner-straightening equipment 4 and the measuring cart 5 containing a movable base 6 and the sensor 7 of the spatial position of the measuring truck 5, is rigidly mounted in the center of the specified movable base 6. The sensor 7 is strictly oriented on the head of the adjacent rail of a railway track, which is in this technical solution, the measurement base 8. The specified orientation of the sensor 7 measuring base on a support 8 is provided that it is installed on a fortified angle predominantly in the 90° (±3°) relative to the direction of motion of the center of the movable base 6 guide elem�NTE 9, on the bottom (facing the track). In this case the guide element 9 is designed so that its opposite end upon movement of the track machine for leveling path 2 slides on the head of the adjacent rail track. This ensures strict orientation of the laser beam of the measuring sensor 7 base 8.

As the sensor 7 can be used, for example, a laser rangefinder with inclinometer, for example, type Disto 8, with the system of measurement range 1 and the angle of inclination β relative to the horizon. In addition, as the sensor 7 can be used means which does not need to force the orientation, for example a laser scanner with a given scan angle.

In the upper part of track machine (on its roof) antenna 10 satellite receiver 11, wherein the phase center of the satellite antenna 10, preferably, is on the vertical axis passing through the center of the movable base 6 of the measuring bogie 5. Satellite receiver 11 is connected with the first information input of the onboard computer 12. Other information inputs of the onboard computer 12 are connected to the outputs of the sensor 7 and the sensor 13 of the angle of inclination of the track machine. The output of the onboard computer 12 is associated with liner-straightening equipment 4. Through the modem 14 satellite receiver 11 may be associated with equipped�and satellite navigation equipment base (or referencename stations) 15. Described above is a satellite positioning system performs the function of a high-precision device for determining the distance and provides the spatial reference design data and calculation of distance traveled on the current coordinates. In this case to determine your progress in this unit can be used odometer (measuring wheel is provided with a speed sensor).

Work on the b train tracks, according to the invention is as follows.

Before you start leveling works by measuring the spatial coordinates to make adjustments in-situ position of the neighbouring leveling rail journey to account for possible changes in its spatial position, from planning to start leveling works. One of the threads (rail) of the said adjacent path taken for the measurement base 8. In accordance with the received spatial data measurement base 8 is known in geodesy dependencies define the design position straighten all the way, 2 in terms of (linear) and angular (in the profile) relative to the measurement base 8. That is, updating of the design data. If necessary, the data are interpolated with the "step" that takes into account the curvature of the rails and functionality leveling machines (for example�EP, for data the spatial position of the reference path is taken as the measuring base, with an increment - 0.1 m).

The coordinates of the measurement base 8, as well as received, corrected design data straighten all the way 2, the distance 1 between the axis straighten all the way 2 and the measurement base 8, and the angle β, which determines the height position straighten all the way 2 on the specified gauge length 8, are recorded in the onboard computer 12 track machine.

When moving track machine measurement system 5 moves along the leveling path 2. Thus the spatial position of the center of the movable base 6 is changed in accordance with the current situation straighten all the way 2. The sensor 7 detects the change of the spatial position of the center of the movable base 6 of the measuring truck 5 in plan and profile in relation to the measuring base 8 by measuring the angle β is the deviation of the sensor 7 from horizon that determines the current position of the height h of the center of the movable base 6 relative to the measurement base 8, and the distance 1 from the center of the movable base 6 to a measuring base 8. Thus measured current (changing) distance values 1 and angle β, characterizing the spatial position of the measuring bogie 5 relative to the measurement base 8, are fed to a second input of the onboard computer 12.

Side to�mputer 12 the authors have developed a special computer program, at set intervals, the way compares the respective current spatial coordinates of the measuring base current values 1 and β from their design values, is tied to spatial data (coordinates) straighten all the way.

According to the difference of the current and project units 1 and β in the computer 12 software produces the control signal supplied on liner-straightening device 4, which moves straighten all the way 2 up until the current value 1 and β will be equal to their design values.

Wherein when the movement track machine in the computer 12 simultaneously receives the following information:

- information from a satellite positioning system, the receiver 11; (which allows binding of the measured data to the current coordinate of the path).

- the angle from the sensor 13 for the introduction of amendments to the deviation of the axis of the antenna 10 from the vertical and calculate the magnitude of reduction;

- data on the spatial position of the center of the movable base 6 of the measuring bogie 5 relative to the reference measurement base 8, as described above.

All current information from the sensors 7 and 13 synchronizes the timestamps of the satellite positioning apparatus 11 coming in the computer 12.

The device according to the invention is inexpensive and reliable in the e�operation. While the technology works, which is realized with the use of this device ensures the high quality of the alignment, at the expense of the used measuring base, immune to shocks and changes of spatial position in the process of straightening. While the measuring base may be curved, which helps to reduce material and financial costs of creating artificial rectilinear measurement bases, such as laser reference planes or copier-strings. Updating the spatial position of the measuring base directly in front of the bearing (e.g., GNSS) ensures efficiency and high granularity (≤1 m) in the definition of the coordinate measuring base and their interpolation, and further high accuracy of setting the path in the design position.
