The invention relates to devices for monitoring the status of superstructure and can be used in the operation of rail rail and subways, in particular turnouts to determine the integrity of the wag.

It is known that at the turn of wit, almost inevitable derailment with rails, which often leads to a train wreck with the most severe consequences. Transverse thrust of the drive mechanism of the switch does not prevent longitudinal movement of the part of the wag after its break, and the cars after derailment go in different directions and can collide with oncoming train or fork of the tunnel. As practice shows, to date, no reliable technical means for monitoring the integrity of wit, and control is provided only by visual or flaw-detection inspection path in the daylight crawl - rail transport or night - in the subways. Therefore, in this situation, in the period between examinations, islomania to wit, it may take a large number of trains. Due to the nature of the design of switches, the switches will not pass current circuits Autolock, but because, unlike running (adjacent) rails, break someone said controlled signal is Lamy Autolock.

It is known a device for recording the status of switches and crossings, comprising a housing and a sensor end position of astramovich rails, which allow you to diagnose wear and to determine the interval between preventive examination (patent RF №2013262, MKI 7 61 K 9/08, 1989).

This device has limited functionality, i.e. it does not provide control over the longitudinal movement of wit (along the frame rail), and also does not preclude such moving parts of wit, if the fracture and does not hold on the place mentioned part for safe crossing of trains, under which there was a break.

The objective of the invention is to improve the safety and functionality of the device by enabling the release signal, and also due to hold a free part of the wag after fracture of the latter.

To solve this problem, an apparatus for controlling the condition of the wag switch (on the basis of control provisions of wit), containing resistant Shoe that is designed to limit the movement of wit, after its break along the frame rail path, and the sensor controlling the position of wit (hereinafter - sensor), made in the form of stationary and movable contacts, intended for electric circuit is a Bishop with the longitudinal movement of wit, at a certain distance from its end position, resulting in shunting of track circuits Autolock, while stationary contact electrically connected to the adjacent frame rail and is isolated from the second frame rail, and a movable contact connected to the second frame rail, isolated from the adjacent frame rail and installed with the possibility of force interaction with a wit and education in electrical connection with the stationary contact.

It is advisable resistant Shoe rigidly mounted on one of the stationary elements of the track opposite the wisecracking, in particular on the inner side of the adjacent frame rail or on the sleepers.

The device should be carried out as a one-time (i.e. for a one-time operation), while the Shoe may be secured to the frame rail, it can be mounted stationary and movable contacts, the latter of which is made in the form of a longitudinally positioned bolt and resistant Shoe is equipped with destructible sleeve of insulating material which is placed in the mentioned movable contact and the stationary contact is connected electrically resistant Shoe.

Further, the movable contact can have a tapered section and can be placed in the corresponding conical hole of the thrust Shoe.

The device posna the tsya drawings, on which:

figure 1 shows a General view of the device;

figure 2 - mounting the device to the frame rail (top view);

figure 3 shows a cross-section of the Shoe.

Device for monitoring the state of wit, switch the track contains resistant Shoe 1 and the sensor 2 (Fig 2, 3) monitoring the status of the wag 3, which is determined by the position of wit, relative to the adjacent frame rail 4. The said sensor is a movable contact made, for example, in the form of a threaded element, a bolt 5, the driving element of which is the end of the wag, and the second, stationary (response) the contact is the Shoe 1 is electrically connected with the frame rail. The circuit mentioned contacts provides a bypass circuits Autolock and supply prohibiting signals for the remote control of switches and/or train driver.

The Shoe 1 is made of electrically conductive material (e.g. steel), fixed to the adjacent frame rail 4 or sleepers (not labeled) and is designed to limit the movement of the wag 3 (1) if the fracture in the horizontal plane along the adjacent frame rail 4.

The Shoe 1 is provided with a sleeve 6 (3) of insulating material, the strength is significantly lower than Shoe or bolt, which passes through a hole in the sleeve 6 (Fig 3) and ele is traceski connected to the second frame rail 7. Instead of the bolt 5 can be applied cone element mounted in a corresponding conical bore of the Shoe (not shown).

The translation of the arrow is equipped with 8 drive mechanism.

To shunt track circuits Autolock stationary contact in the form of the Shoe 1 and the movable contact in the form of a bolt 5 (2, 3) are connected by conductors 9 and 10, respectively, with the second frame rail 7 and the remote control 11 (1, 2) for switching the respective circuits and signals.

The Shoe 1 is mounted on the inner side frame rail 4 opposite the wag 3.

The operation of the device is as follows.

During operation of the switch when the train moves end (pointed) piece of wit, pressed thrust 8 of the drive mechanism to the frame rail 4, and the root of wit, when it is bolted to the adjacent rail.

The impact load from the wheels of the rolling stock can cause stress and fatigue fracture of the wag.

In this case (when moving train) free piece of wit, not coupled as a result of fracture of the latter with the adjacent rail bolts (figure 1 is not marked), moves along the train to the thrust bolt 5 - the rolling contact of the sensor 2, which prevents further movement of this part of the wag. This immediately (i.e. directly point touch) is shunting of track circuits and enable signals on the remote control arrows and then there is a significant (on the order of tens of thousands of Newtons) axial impact someone said on the Shoe, resulting in the destruction of the insulating material of the sleeve 6, and further contact with the specified force of the Shoe 1 and the bolt 5, which provides a reliable electrical connection between the movable contact of the bolt 5 and the stationary contact Shoe 1, and further with the second frame rail 7, i.e. at the same time bypass the respective track circuits Autolock, as well as the actuation of the respective sensors on the signals stop. In the proposed device wag (in case of a break) performs the function of a drive element movable contact sensor, which closes the bypass circuit. The latter gives the possibility to stop the movement of the following trains and fixing someone said lets skip over the break the rest of the train, preventing their descent from the rails.

Then running values of horizontal irregularities of rail lines are found as product of bogie base by deflection of running course of rail lines from running averaged courses of rail lines on bogie base calculated from courses of rail lines. Running radii of curvature of rail lines are found by dividing bogie base by measured increment of course angles of rail lines on bogie base.
