The invention is intended to obtain information about the process of wear of rail mainly in the operation of the path.

Known mechanical profilometer (USSR author's certificate 56346, MKI 61 To 09/08), registering the character of wear in the form of sine sweeps, requiring decryption by means of templates.

For the prototype accepted "Measuring geometric irregularities of the railway track (USSR author's certificate 949030, MKI E 01 35/04), simplifies the process of obtaining the measured parameters.

Known measuring geometric ner the mi and supported by the wheels on the rail track. Measuring and correcting rollers, horizontal base members and their latches high precision measurements on curves and straight sections of the path.

However, in the measurement results present methodological error associated with the choice of reference system.

The purpose of the invention is to avoid methodological errors and facilitate measurement means.

The essence of the invention consists in the execution of the wheeled chassis of the two parts and the addition of the rotary carriage, equipped with basic disks that are measuring levers articulated with electrical sensors. The design allows you to perform measurements relative to the surface of the rails, not subject to wear in use, which gives stable readings intensity of wear from previous measurements.

The drawing shows a simplified kinematic scheme of measuring wear of rail (from three similar carriages fully depicts one).

Measuring wear of the rail has a wheeled chassis, consisting of two parts: the transverse arch 1 and the longitudinal frame 2, which are interconnected movable spring-loaded node 3. Prodolnaia 4.

Chassis is backed by its wheels on the head measured rails 5.

The arch and branches of the frame at an equal distance from the rails installed at least three rotatable carriage 6 by means of a horizontal hinge 7.

Rotary carriage mounted inside track. Rotary carriage have three spatial oriented axis. The end of the axis of the base disk 8 is connected with a horizontal hinge 7. The ends of the other two axes facing the rail and provided with rollers 9.

A basic disk is mounted for rotation in the middle of the carriage. Basic disks are made mostly of cone, at least one of them is provided with a window 10 directed along the radius.

On the inner edge of the window on this disc fixed bearing 11. Bearing set measuring lever 12. With one end of the measuring lever provided with a transverse bar 13, and the other has a pin 14 electric sensor 15.

Cross strap measuring lever opened the window of the rotary disk. The lever is held in the end position the return spring 16. The fastening of the measuring arm to the rotary drive via a support forming an angle of 10-20 degrees between their working surfaces.

The electrical sensor is installed near the center of the base disk in an arc end of the lever.

On each carriage near horizontal hinge fixed pin in the form of an adjustable stop 17 at its position and the springs 18 that communicates with the transverse arch and branches of the longitudinal frame.

Measuring wear of rail works as follows.

When installing chassis rails, each of the heads is covered by a basic disk bottom for its edge and the wheel on the surface.

Wheeled chassis is in contact with a rail gauge of not less than six points.

Multipoint coverage of the rails with tension created by the spring mobile node provides a reliable base orientation of the chassis.

The wheel is offset from the top wearing surface of the rail head. During wear size between the upper surface of the head and the lower edge of the non-uniformly due to the volatility of the pair of wheels relative to the track. Basic disk, having a cone shape, despite changing the size of the height of the rail head, always is in working contact with the bottom edge, but at the same time, despite the lack of wear and tear, the radius of alkatib its lower edge and the point of attachment of the carriage.

Reducing the radius of spinning a basic disk on the edge causes the pressing of the measuring arm and it changes its tilt relative to the rotary disk. The end of the measuring lever retracts into the box and contact is offset from the sensor, which is reflected in its electrical parameter, such as resistance.

Changing the state of the electrical sensor is celebrated United with him by the Registrar.

Basic disk at offset measuring wear of rail displays measuring lever from engagement with a rail on each full turn. Pull the return spring he can't leave the radial window, because its variance is terminated when the focus of the transverse plate at the edge of the rotary disk.

The maximum value of the electrical parameter after a complete turnover of the underlying disk is proportional to the measured height of the rail head.

Measuring wear of rail allows to obtain continuous data over a large area of railway track.

Basic disks when moving in the zone of junction of the rails protected from bumps on butt pads. Protection is accomplished through a pair of rollers. The roller in front of the edge of the base disk ( after butt pads console is held in the raised condition subsequent roller. The subsequent passage of the roller joint plates allows the carriage to be lowered to the operating position. The constancy of the operating position is provided an adjustable stop and a spring acting between the carriage and the transverse arch or branches of the longitudinal frame. The bypass pads is facilitated through mobile node component parts of the chassis.

Reducing the number of component parts of the chassis when home improvement was possible to reduce the dimensions and weight measuring means.

Comparing previous measurement for this site with the current, it is possible to notice the growth intensity of wear not only at a considerable distance, but also locally, i.e. wavy wear.
