Disclosure of the invention.

Calipers are referred to as instrumentation and measurement tools. The principle of operation of the claimed device is mechanical, which has influenced the design of the device. Apply the claimed device for measuring in the open air the elements of the upper structure of the railway transport track with laid rails manufactured in accordance with European standards and allows monitoring the condition of railways.

The inventive track caliper is used on railway transport during construction, repair and maintenance of the track. The track caliper device allows you to get a technical result, which is expressed in the fact that, unlike the analogue, it can be used in the construction of railroads, in the repair of railways, in the implementation of the current maintenance of railways. The device large and small frames that move freely along the rod and can be fixed in the desired position allows to obtain the specified technical result. The device of the sponges makes it possible to measure the vertical and lateral wear of the rail head in the open air and repair of railways. Thus, the arrangement and location of short jaws in the caliper allows you to measure the pitch of the tongue, the width of the groove between the frame rail and the counter rail, the width of the groove between the guardrail and the core with high accuracy.

Such a device and the location of the lever on a large frame, in which it becomes possible to move the frame with the support engine, so that the frame with the support engine moves along the lever allows you to make accurate measurements during the construction of railways.

The declared caliper has in its composition a depth gauge that allows you to measure the depths of the holes and hollows, these properties of the declared calipers allow you to achieve such a technical result as the implementation of measurements in the open air during repair and maintenance work to monitor the current state of the railways, due to the fact that depth gauge is rigidly connected with a large frame.

Such a technical result, such as obtaining accurate measurements, is achieved due to the specific features of the device of the inventive calipers, namely, the lever and frame of the lever with the support engine have a clamping device, and using the support engine and long sponges of the rod and the large frame measure the reduction of the wit against the frame rail.

The inventive track caliper consists of a bar with a scale, a long bottom and a short upper jaws. On the long sponge rod is a movable stop, fixed clamping device. On the bar are based a large frame with a nonius, having a lower long and upper short jaws, and a small frame. Both frames have the ability to move along the rod and secure in the desired position by clamping devices. Long sponges of a bar and a framework are big equipped with carbide measuring tips. With the help of long jaws, the vertical and lateral wear of the rail head is measured, and with the help of short jaws, the pitch of the wit, the width of the groove between the frame rail and the contra rail, and the width of the groove between the guardrail and the core are measured.

Also on the large frame there is a lever along which the frame with the support slider will mix. With the help of the support engine and long sponges, the bar and the large frame measure the reduction of the tongue against the frame rail. The lever and the frame of the lever with the support engine have a clamping device.

With a large frame rigidly connected depth gauge to measure the depth of the holes and hollows.

In the groove of the small frame moves the engine with two index bars, with which they measure the vertical wear of the core and guardrail. Engine provided with a clamping device. On the small frame there is a rigidly mounted clitz, with which the gap in rail junctions and turnouts is measured.

Such a technical result, such as the implementation of accurate measurements in the construction and repair of railways, is achieved due to the special design of the engine and its location in the inventive slide gauge, namely, the engine moves in the groove of the small frame, the engine has two indicator strokes, the engine has a clamping device, as it is rigidly installed on the small frame, the clitz, then it allows, in contrast to analogs, to make accurate measurements of the rail clearance in rail junctions and turnouts, which makes the claimed caliper traveling track fungible with repairs and carrying out maintenance work on the railways.

With the help of the inventive track caliper, the vertical wear of the head of a wit-rail used in the structures of the upper structure of the railway track and for the manufacture of turnouts for railways of industrial enterprises is measured. With the help of the support engine, long sponges of the rod and a large frame of the inventive caliper, measurements are made of the reduction of the tong against the frame rail, and the lever and the frame of the lever with the support engine have a clamping device.

Using the proposed track caliper, the lateral wear of the rail head is measured using long jaws, the claimed device allows you to take measurements at the tip of the wits and in the most worn place with high accuracy.

The inventive device allows you to measure the reduction of the wit against the frame rail is measured in cross section, where the width of the head of the wit on top is 50 mm, i.e. where the wheel begins to move from the wit to the frame rail during the sweeping movement.

With the help of the inventive track caliper, the vertical wear of the core of the cross is measured along its longitudinal axis in cross section.

Depending on the measured parameter of the rail, the reading is performed on the appropriate scales using measuring and working surfaces of calipers. The inventive vernier calipers measures length in millimeters (mm).
