Description

The invention relates to the field of railway transport and can be used in warning devices of repair crews on the way of a train approaching. Known devices and repair brigades on the way to the approach of a train, containing electric auto-blocking circuits, power supply units connected to rails at one end of the circuit, and track relays at the other, signal installations, communication lines and dispatch control lines, dispatcher control generators, power sources, signaling units, connecting blocks, a capacitor and resistors are connected to it. A disadvantage of the known devices is the complexity and low reliability of operation. With increased reliability and simplicity in the proposed device, at each signal installation there are two additional receivers, the inputs of which are connected in parallel to the dispatch control line, and the outputs are connected to the inputs of the corresponding auxiliary relay, warning relay and pulse relay, and the power source is normally the closed contact of the first actuating relay is connected to the windings of the alarm relay and is connected through a capacitor and connecting blocks to the COMMUNICATION line; connected at the other end with the input of the alarm unit, the other inputs of which are connected to another power source through the communication unit connecting terminals to a normally open contact of a pulse relay, one winding terminal of which is connected to the power supply directly, and the second through normally closed and serially connected relays Alert and track relay is connected to the other pole of the Yitani source, and the rear contact of the track relay is through the normally open contact of the second executive barely also connected to the second terminal of pulse relay coil. The drawing shows a schematic plan of a railway section equipped with an automatic blocking, dispatch control, and a schematic diagram of the notification of the repair crews. Auto-blocking devices are connected to the rail circuits x and 2: power supply units 3 and 4, signal installations 5 and nut relays 7 and 8 rail circuits / and 2, which control the generators 10–12 of the dispatch control, connected in parallel to the link 13 d) of the satellite control For notification devices, additional receivers M and / 5 are installed, connected in parallel, the tuning frequency of which corresponds to the frequencies of the generators 10 and //

dispatcher control installed on two adjacent signal installations. Outputs 14 and 15 are connected to relays 16 and 17. POWER SUPPLY 18 is connected via front contact 19 of executive relay 16 to o & MO broadcasting relay 20, which through capacitor 21, linear circuit 22, laid between signal sets 5 and 5, is imperative 23 and sockets 24, connected in parallel with linear line 21 and located at a certain distance from each other (for example, 50-100 m), are connected to the pin 25 of the plug-in connector 26 of the warning block (howler) 27. The source of titanium 28 is through the front contact 29 of the relay 20 power on contact, the front contact 30 of the track relay 8 of the rail circuit 2, whose open rear contact through the normally open rear contact 31 of the executive relay 17 is connected to the front terminal 30, sequentially connected to the pulse relay 32. The power source 33 through the rear contact 34 of the pulse relay 32 sequentially connected to power line 35, in parallel with which jacks 36, located in the same places as jacks 24, are connected for connecting, via pin connector 26, to the signaling unit (roar) 27.

The device works as follows.

To alert in the area of the track circuit 2 and the absence of trains on the track circuits / l 2, the track relay 7 receives power from the rail track / from the transmitter 3 of the signal installation 5. The signal from the dispatcher control 10 heater, controlled by the track relay 7, is fed to the lipia 13 is a controller and is received by receiver 14, at the output of which actuating relay 16 is energized.

If the track circuit behind the signal installation 6 is free, then from the dispatcher control generator 12 via line 13 of the control control signal is fed to the receiver 15, the output relay 17 of which is also energized. The alarm activation relay 20 is supplied with power from source 18 through the closed front contact 19 of the executive relay 16. The impulse relay 32 receives power through the front contact. The contact 29 of the alarm activation switch 20, the front contact 30 of the track relay 8 of the rail relay 2. Through pulse 34 of the pulse relay 32, a pulse line is sent to the pit line and 35 to the leads 36. The warning unit (a boarder) 27, connected, for example, at point L to power supply lily 35 through jacks 36, using a plug connector 26, sends intermittent signals characterizing the absence of trains to rail circuits x 1 or 2 or / and 2.

When the train track 1 is occupied with a head, track circuit rail track relay 7 receives a signal and turns off the output of dispatcher control generator 10 from dispatch control line 13. Receiver 14 does not receive a signal, the auxiliary relay 16 is depleted and by its contact 19 disconnects the power supply 18 from the winding of the relay 20. The contact 29 relays 20 times. 34 delivers a continuous signal from the power source 53 to supply line 55 to slots 55. The notification unit 27 connected to supply 35, through slots 36 and the connector 26, sends a continuous signal indicating that train P1e is closer to the work site on the rail circuit 2. P When the train head enters the track circuit 2 signal: alerts continue. The power supply circuit of the pulse relay 32 will additionally be opened by contact 30 of the track relay 8 of the rail circuit 2. The alert will continue even if the train has a rail circuit 2 and its rail circuit is missing ;; and /, since the power circuit of the pulse relay 31 will be disconnected contact 30 track relay 8.

As soon as the train head zaschuntirueg

rail circuit, protected by the signal setting 6, the track relay 9 disables the output of the generator 12 of the dispatch control from the line 13 of the control control. Receiver 15 does not receive a signal, and executive relay 17

de-energized. Immune relay 52 receives power from source 28 through a closed froite contact 25 of the alarm switching relay 20, which is energized through front contact 19 of the secondary relay 16, rear contact 30 of the traveling relay 8 and rear contact 31 of the executive relay 17. When the track 2 circuit is released, the power supply circuit of the relay 52 is created by the front contact 30 of the track relay 8. As the guard goes from the signal set 5 to the signal set 6, the deceleration time for the dropping of the warning relay cor 20 increases by switching on 25 different resistances jumper plug 25

connector 26 of the alerting unit (howler) 27. With similar devices, you can use another direction of movement. Thus, using the automatic blocking devices, dispatching control, adding to its receivers and relay circuit, you can get a simple alert system for repair crews.
