This technical solution is taken as a prototype of this utility model.

However, it has disadvantages.

In the device for determining the spatial parameters of the rail track of the prototype, the trolley with the chassis contains wheels: two measuring wheels and one support, which are in contact with the wearing part of the rails, and a measuring wheel, while the measuring wheel associated with the sensor of the traveled path does not provide continuous registration of the track on the rail joints and turnouts, all this reduces the accuracy of determining the coordinates of rail threads and does not provide the ability to obtain reliable values of the desired parameters.

The present utility model is based on the solution of a problem that makes it possible to increase the accuracy of determining the coordinates of rail threads, to ensure the accuracy of measuring the distance traveled during the passage of rail joints and turnouts.

According to the utility model, this problem is solved due to the fact that the measuring trolley for determining the geometric parameters of the railway track with software contains a running gear, including measuring wheels located along the axis of one of the rails, on the rod, a support wheel connected to the measuring wheels by a transverse rod , and an information-recording system containing a heading indicator with heading, roll, and pitch sensors located on a rod above the axis of the rail carrying the measuring wheels, the rail track sensor located on the transverse rod along its axis, and the distance sensor connected by outputs to the controller connected to the computer.

The measuring wheels are made in the form of a pair of cylindrical wheels having a vertical and horizontal axis, and each of the measuring

wheels with a horizontal axis in contact with the tread surface of the rail head, equipped with a distance sensor, together providing continuous registration of the distance traveled during the passage of rail joints and turnouts, each of the measuring wheels with a vertical axis is in contact with not wearing part of the rail head, but along the transverse the rods are equipped with an inter-rail distance sensor, the measuring tip of which is in contact with the non-wearing part of the rail, and two gauges of gauge will measure the tips of which are placed on the same line perpendicular to the axis of the rod with the measuring wheels are in contact with the wearing part of the rails at a predetermined height from the rolling surface and allow to jointly measure the rail spacing, track width and wear of the rail heads, while the measuring tips of the rail track and track width sensors are made with manual withdrawal, excluding their falling into the gaps of rail joints and on turnouts.

The measuring trolley comprises a running gear 1. The running gear 1 includes measuring wheels made in the form of a pair of cylindrical wheels 2 and 6. The first pair of cylindrical wheels 2 contains wheels with vertical 3 and horizontal 4 axles. The second pair of cylindrical wheels 6 contains wheels with vertical 7 and horizontal 8 axles. The first 2 and second 6 pairs of cylindrical wheels are located on the rod 10 along the axis of one of the rails. Cylindrical wheels 4 and 8 with the horizontal axis of each pair of 2 and 6 measuring wheels in contact with the rolling surface of the rail head. Cylindrical wheels 3 and 7 with a vertical axis of each pair of 2 and 6 measuring wheels are in contact with the non-wearing part of the rail head.

The chassis 1 includes a support cylindrical wheel 11 with a horizontal axis. The supporting cylindrical wheel 11 is connected with the pairs 2 and 6 of the measuring wheels of the transverse rod 12.

The measuring trolley contains an information-recording system containing a heading indicator 20, a track gauge 13, gauges 15, 17 and track sensors 5, 9, the outputs of which are connected to the controller 24. The controller 24 is connected to the computer 25. The measuring trolley is a mobile tool with a short base, for example, 1 meter.

The heading 20 with heading sensors 21, roll 22 and pitch 23 is located on the rod 10 above the rail axis of the carrier pair 2 and 6 of the measuring wheels. As sensors kurokrenoukazateli 20 used, for example, laser gyroscopes type KM-11-1 A.

The track gauge 13 and the gauges 15 and 17 are mounted along the axis of the transverse rod 12. The measuring tip 14 of the track gauge 13 is in contact with the non-wearing part of the rail. The measuring tips 16 and 18 of the gauges of gauge 15 and 17, respectively, are placed on the same line perpendicular to the axis of the rod 10 and are in contact with the wearing part of the rails at a given height from the rolling surface. The measuring tips 14, 16 and 18 allow you to jointly measure the track distance, track width and wear of the rail heads. The measuring tips 14, 16 and 18 of the gauge 13 and gauges 15 and 17 gauge made with manual tap, excluding them from getting into the gaps of the rail joints and turnouts. As

the track gauge 13 is used, for example, a sensor of type HDL12, and the gauges of gauge 15 or 17 are used, for example, an inductive sensor.

Cylindrical wheels 4 and 8 with the horizontal axis of each pair of 2 and 6 measuring wheels are equipped with sensors for the distance traveled 5 and 9, respectively. The sensors of the distance traveled 5 and 9 together provide continuous registration of the distance traveled during the passage of rail joints and turnouts. As a sensor of the traveled path 5 or 9, for example, a rotation sensor E40H incremental encoder is used.

Determination of the geometric parameters of the railway track is as follows.

The weight of the trolley provides power closure of the first 2 and second 6 pairs of measuring wheels with a horizontal axis 4, 8 and the support wheel 11 with the rolling surface of the rail heads.

The power short circuit of the first 2 and second 6 pairs of measuring wheels with a vertical axis 3, 7 and the measuring tip 14 of the track gauge 13 with a non-wearing inner surface of the rail heads is ensured by the manual retraction force 19.

The power circuit of the measuring surfaces of the gauges of gauge 15 and 17 with the surfaces of the rail heads at a height below the rolling surface is ensured by their measuring force.

All sensors are pre-calibrated.

When the trolley moves according to the sensor signals, the paths 5 and 9 are taken and recorded in the memory of the sensor readings: heading 21, bank 22, pitch 23, track distance 13, gauges 15 and 17 gauge.

The running of the measuring carriage with measuring wheels, each of which is made in the form of a pair of cylindrical wheels with vertical and horizontal axes, equipping the wheels with cylindrical axes with sensors of the distance traveled and their interaction with the rolling surface of the rail head provide continuous registration of the distance traveled when passing rail joints and breaks on turnouts, increasing the accuracy of measuring the distance traveled.

The contact of the measuring tips with the rails is transferred to the non-wearing part of the rails, which increases the accuracy of determining the coordinates of the rail threads.

Equipping the measuring trolley with an information-recording system allows you to use this mobile tool with a short base, for example, 1 meter, to determine the deviation of the path from the design position, to determine the radius of curvature of the rails, including on the turnout switch, to perform calculations of the bending arrows of the rails in the plan (straightening) and subsidence arrows on each rail thread without restrictions on the length of the measuring base, for measuring the track gauge, the excess of one of the rails and the wear of the rail heads.

The proposed measuring trolley is manufactured industrially at the company NPF Zavod Izmeron, and equipping it with an information-recording system is carried out by those known in the measuring

appliances and this determines, according to the applicant, its compliance with the criterion of "industrial applicability".
