Description

The object of the present invention is a device for acting from a path on signal and brake devices on a moving train using in-path inducers interacting with receiving inductors mounted on a steam train. A distinctive feature of the device according to the invention is the connection of the windings of two-winding electrodynamic devices (for example, electric motors) controlling the corresponding brake valves to different receiving inductors located at some distance from one another. In this case, the device operates only at the moment of simultaneous passage of the two receiving inductors feeding its windings over the corresponding traveling inductors brought into operation, thereby obtaining several steps of braking. Track inductors can be made; in the form of a permanent magnet with a winding that serves for Po 10 Code c. five.

giving an electrical impulse to other traveling inductors at the moment of passing the train.

The invention is illustrated in the drawing, in which FIG. 1 shows a diagram of the device, and FIG. 2 and 3 details of the device.

In one of the strings of the rail track (Fig. 1), three small sections A, A and Dd of the rails were isolated, isolated in a magnetic relation from one another and from the adjacent sections of the rail track by inserts MI from a diamagnetic material. The dimensions of the selected areas must be matched with the distances between the centers of the axes of the engine intended for movement along a given path, so that the distance between the inserts of the diamagnetic material is exactly equal to the distances between the axes of the engine.

The rail track section A is equipped with a special rail having small inserts 1, 2, 3 of diamagnetic material. About the middle of this stretch

van track inductor NS, a permanent magnet with winding I.

Plot L can also be equipped with a conventional rail without inserts 1, 2, 3 of diamagnetic material, but in this case, 3-4 track inductor (Fig. 2) with permanent magnet cores should be installed over the plot, connected in parallel.

In the latter version, the track inductors can be arranged in the following way: several permanent magnets (Fig. 3) are attached to the rail section in the lower part of the rail head (Fig. 3), the windings of which are also connected in parallel.

Approximately in the middle of sections A and Ld of the rail track, track inductors with iron cores C and C.2 were mounted, on which windings I and Y were laid.

One ends of each of the windings of all three track inductors are interconnected, and the second ends are retracted to the station and connected to the terminals of the switches Pj and P (Fig. 1).

The engine consists of three receiving inductors, made in the form of windings I, Yaz and Yav, superimposed on the axis of the QY, KYAZ and KYAZ, three electric motors E, E and E and a four-digit keb-signal, controlled respectively by four relays K, F, 5 and 3 red, yellow, white and green lights.

The electric motors E, E. and Ed set in motion, respectively, the brake valve TC and the brake valves (decelerating) and TYADE motors E, E. and Ed operate only when simultaneously driving the stator and rotor windings. Relays K, F and B of the red, yellow and white lights of the cab signal each have two windings and work only with simultaneous supply of current to both their windings, relay 3 of green fire has one winding and is triggered when current is supplied to it.

The ends of the winding and the receiving inductor are connected to the stator electro146

motor E. From the same winding I there are parallel branches to the stator of the motor E and to the relay / C and F of the red and yellow lights of the keb signal, as well as to the relay 5 of the green fire of the keb. The last circuit is interlocked with the brake valves in such a way that the green signal lights up when the valves are closed and goes out when these valves are activated.

The ends of the winding I 5 are connected to the stator of the electric motor Ed and to the rotor of the electric motor Ed, as well as to the relay J and B of the yellow and white lights of the keb signal.

The ends of the winding Yab brought to the rotors of electric motors 3 and Ez and to the relay / and B of the red and white lights of the cab signal. In this case, the rotor winding circuit of the motor E is blocked with the tap TKz in such a way that it is closed when the brake crane is inoperative and turned off when the latter is triggered.

Receiving several stages of braking is performed by closing either one station knife switch PI or P of both knife switches Pj and РЗ simultaneously.

If the switches R and RZ at the station are open, then when passing a locomotive equipped with the described device along a selected section of the path, as a result of current induction in the windings I, I, and I of the receiving inductors, when the latter pass over the path inductor NS, only the relay 3 green fire is activated A steam train lights up a green cab light.

If the RZ switch is closed at the station, then, due to the connection of the windings I and Ya of the path inductors, when the locomotive passes, the current will be induced simultaneously in the windings I, Jaz of the receiving inductors. In this case, the current will wrap only the windings of the stators of the electric motors E and Ez, both windings (stator and rotor) of the electric motor E, both windings of the relay W yellow fire of the keb signal, winding of the relay 3 of the green fire of the keb signal and one winding of the relay K and B of the red and white lights

cab signal. As a result, the yellow fire KS signal relay will operate, and the Ez electric motor controlling the brake crane will come into rotation. The green fire of the cab signal will not burn due to the presence of interlock with the brake valve.

If the PI switch is closed at the station, then, due to the connection of the windings // 1 and Jaz of the path inducers, when the locomotive passes, the current will be induced simultaneously in the windings And And And of the receiver inductors. In this case, only the stator winding of the electric motor 3.2 will flow around, only the rotor winding of the electric motor Ed, both windings (stator and rotor) of the electric motor E, the winding of relay 3 of the green fire of the signal, both windings of the relay / {red fire of the keb signal and one winding of the relay M and B yellow and white cab lights. As a result, the red fire cab signal relay is activated and the motor E, which controls the brake valve, is set into rotation, so that the green fire of the cab signal will not light up.

If both switches P and P.2 are closed at the station at the same time, then due to the connection of all three windings MI, 2 and I of inductors when the engine passes, the current will be induced simultaneously in all three windings of I, Poison and I receiving inductors. As a result of the current flow around the corresponding windings, electric motors E., and Ed will operate, which will activate the brake valves T1 {., And TKz- The white fire of the keb signal will light up simultaneously. The motor 3j will not work, due to the breaking of the chain of its rotor by the brake valve. For the same reason, not

The red and yellow cab lights illuminate. The green light of the cab does not light up due to the presence of an interlock with the brake valve TK. The action of electric motors (threading from receiving inductors and effects on brake valves) can be performed not only directly, as shown in the diagram of FIG. 1, but also indirectly, i.e., through a relay, an amplifier, etc., apparatuses.

Bringing brake cranes to their original position is not included in the proposal - it is assumed that existing methods can be used for this purpose.
