In the cabin there is a system of process control by measuring the orientation of the laser beam relative to the reference points, including fixed point outside the path, and a computer data processing system. The measurement process is controlled by the operator from the cab.

The known method and device for measuring the width and deviation in terms of railway track in the form associated with the traction means of the measuring bogie, axle boxes which relies timber base with opposite left and right rails sensors, some of which create eddy currents so that the created magnetic flux is parallel to the longitudinal direction of the ski, each the turn of the receive path via the traction means of the system processing the measured values and bind them to the plan.

The complex also has a surveillance system contact network analyzing unit, two locating infrared sensors, three television cameras, two VCRs, two visual display devices and other devices, video surveillance and data processing.

Non-contact measurement system using the latest technical tools and provide a multidimensional condition monitoring path siting, the company shall:

the complexity and high cost of the technical means employed, and the complexity of maintenance, the need for process control measurement and data processing by experienced operators;

obtaining information only after complex processing of data and the lack of control and assessment of the ways in individual parameters at the time of measurement;

There are various devices and systems for automatic measurement of parameters of railway track with sensors that can detect these parameters as a result of contact of the wheels or rollers measuring trucks with rail track with instant readout and data logging.

A device control gauge railway track containing the vehicle on the carrier trolleys mounted on it measuring system, comprising a frame with the attached measuring rollers and displacement sensors measuring rollers associated with the device display and registry and rear tension truck, measuring cart associated with these trucks via the cable system formed by at least one flexible base line, and the position indicator flexible base straight, educated cargo, as well as contact sensor associated with the load and interact via video with range [5].

A device for measuring the level of the railway track in the form of a measuring trolley containing a frame supported on two pairs of wheels for mounting on rails mounted on the frame level sensor and the evaluation unit, electrically connected to the level sensor, and one pair of wheels attached to the frame and the other connected through a rotary spreader [6].

Known contact devices of the control of the railway track are simple and reliable, provide automatic measurement of parameters with instant readout and data logging and convenient for local control gauge for the purpose of Troubleshooting, and quality control of repairs.

A disadvantage of the known potenzmitteln devices is their narrow purpose, the inability to simultaneously control the way in various parametri functionality selected as the closest analogue device for determining the position of the path in the plan, transverse and longitudinal profiles [7].

A known device for measuring parameters of the railway track is made in the form of three connected with railway traction means of the measuring carriages, containing the frame with the attached obkatyvalisj rails of a track, telescopically extend wheels, and mounted measuring devices; however, the two trolleys are oriented in one direction and one in the opposite. Bogie frames made in the form of pivotally United the divergent angle of the elements, the ends of which are fixed obkatyvalisj gauge wheel and provided with telescopically expanding spring-loaded rods, clamping wheels to the rails. Truck pivotally connected to each other and attached to the traction means on the front or rear. The measuring device in the initial position is placed in the container, mounted on the middle frame can be rotated around a transverse horizontal axis and around an axis lying in the plane perpendicular to the axis, and fixing from rotation around these axes on urbameco placed on the container. For protack way to its longitudinal and transverse axis located in a horizontal position. Turn the container around its longitudinal axis and in the plane of symmetry of the truck to determine the true configuration of the surface of the original plane of the track in space. This position of the container in the space taken for the initial "zero". When the device movement reject the provisions of the surfaces following sections of rail track relative to the origin (zero) of the three-dimensional coordinate system space capture devices, for example, gigroskopicheskimi.

With the known device with three trucks, the extreme of which is oriented in the opposite direction, it is possible to perform automatic measurement of the deviations of the provisions of the rail track by several parameters for forward and reverse motion of the traction device.

The disadvantages of the known system for measuring parameters of railway track are:

the inconvenience of operation associated with difficulties transfers from the working position to the transport position and Vice versa, as well as the inability to control the measurement process and the direct observation of the results from the cab traction slicethe condition of the rail track parameters in particular, arrows bend both rail thread and the longitudinal height (trough) rail thread related to the fact that measurements of parameters produce relative to the origin (zero) of the three-dimensional coordinate system space, not relative to the actual landmarks like the frame of the vehicle, the axis of the measuring system, etc.

The objective of the invention is to improve the operating conditions and process control measuring device and the empowerment of measurement parameters describing the actual condition of the railway track.

The problem is solved due to the fact that when using the essential features characterizing the known device on the go train, made in the form of three connected with railway traction means of the measuring carriages, containing the frame with the attached obkatyvalisj rails gauge wheels with axles made telescopically extend through the respective power cylinder and mounted measuring devices; however, the two trolleys are oriented in one direction and one in the reverse direction, in accordance with the invention, and the bottom - on the other bogie frames made in the form of pairs of bearing shafts, one end fixed on axes with values traction means and bearing on the other ends of the axis obkatyvalisj gauge wheels, each of the trucks frame rotary shafts are suspended by means of a power cylinder on the frame of the traction means, each of the axes obkatyvalisj wheels are made telescopically extend through the respective power cylinder, and measuring devices are installed on trucks and associated with indicating and recording devices in the cab of the traction means.

The preferred embodiment of the measuring device on the go train involves fastening the two measuring trucks to buxom one axis of the traction means, and one to the other axis so that one truck is located between the axes and the other two truck - axes, the device is equipped with sensors boom bending mounted on the wheel axles of one and the other cart, sensor rail gauge mounted on the axis of the truck, located between the axes with values, position sensors frame height set on axis with the values of one of the trucks, located on the outer side of the axis of the traction means, and godleski dont forget, and dipmeter mounted on the frame of the traction means.

Swivel pendant measuring trucks on axes with values trolley improves the operating conditions of the device, in particular, provides an easy and quick transfer from provisions for transport to working position and Vice versa, and also creates the opportunity to observe the results of the measurements are indicating and registering in the cab.

Running trucks in a pair of bearing shafts, one end fixed on axes with values railcars, and bearing at the other ends of the axis obkatyvalisj wheels and swivel suspension shafts by means of a power cylinder on the frame rail and extracting telescopic axles trucks with the help of the power cylinders fed from a compressor on the vehicle, provides a simple and reliable manipulation of trucks in the process of working with management directly from the cab.

The location of two trucks with the outer sides of the axes of the traction means and one truck between axes provides the maximum elongation of the measuring system and its axis, which increases the accuracy of the measurement of some parameters, for example, the longitudinal height (trough) rail lines.
