SU70886A1 - Device for single-track semi-automatic blocking - Google Patents

Description

The present invention relates to a device for single-track semi-automatic locking. A feature of the device is the inclusion in the supply-and-receive circuit of signals of windings of linear relays, which close the circuits of self-blocking relays. The latter disconnect the linear relays and control the traffic lights.

FIG. 1 is a diagram of the device for station A, and FIG. 2 - for station B.

The device is intended for the equipment of single-track spans between stations and posts of intra-plant railway transport.

The main parts of the device are.

1. A switch with a horizontal contact system, designed to give permission to receive a train from an adjacent station (position a) and to open the output signal if there is permission from an adjacent station (position b).

2. Signal relay type Нр-1 with a 1000 ohm bias coil, designed to open the output signal and automatically close it along the train.

3. Pedal relay type Нр-1, with a coil resistance of 2 ohms, connected to the rail contact circuit (Lykov’s pedal) and intended to unlock the vehicle when the train passes.

4. Double linear relay for 7000 turns with coil resistance of 240 ohms, which is triggered by giving consent to one of the stations and connecting the power to the blocking relay lines.

5. A double interlock relay for 14,000 turns with a resistance of 480 ohms for blocking the line, connecting power to the signal relay and turning on the span occupancy control signal.

6. Blocking dual relay output signal for 7000 turns, designed to block the output signal when a train is received from a nearby station.

7. Electric meter with a winding of 3 V, recording each opening of the output signal.

8. Auxiliary button, connected in parallel with the rail contact and used to artificially unlock the equipment when canceling the previously issued permission to receive the train.

9. Light bulbs of the span control (white and red) connected to the power supply circuit through the contacts of the blocking relay line.

10.Lamps of repeaters of lights of the entrance and output traffic lights.

11. Mechanical lock-switch of the traffic lights.

12. A wrench for stations where it is required.

13. Step-down transformer for powering lamps of traffic lights and repeaters from the AC network.

14. Two-half-wave rectifier on two 2V-400 kenotrons with rectified current power up to 0.3 a.

15. A battery of three elements for powering the pedal relay and the electric meter.

16. Entrance and exit traffic lights 17, rail contact 18 and two-wire inter-station line 19.

The action of the device when sending and receiving trains is as follows.

In the normal position of the switch 1 with the horizontal contact system turned on in order to send the train from station A to station B, the duty officer of the station L requests the departure to the station by duty station B. Having received the consent, he sets the switch to the position “post. After the dachn, agree with the duty station B to set the switch / of his apparatus to the position “reception. With the appearance of a red span control point (after 1-2 seconds), it returns the switch / to the normal “off” position.

Upon receiving permission from station B by blocker at station A, the prohibiting (red) light of the output traffic light switches to permitting (green), which is used for the train departure.

Simultaneously with the switching of the lights of the output traffic light, the electric meter 7 of the apparatus A of the station A is triggered, showing the sequence number of the obtained resolution, which is recorded in the table logbook against the number of the sent train.

The sent train, after passing by the first slope of the pedal contact 18, located between the input and output traffic lights, automatically closes the output traffic light behind it and unlocks the station A. The device of station B is released upon arrival of the train at the station.

If it is impossible to send a train at an already obtained permit, the duty station A informs the duty station B about this and, specifying the number of the received permit, asks for manual unlocking of the vehicles. After receiving the agreement, the attendants of both stations break the seals from the auxiliary buttons and release them. Before the seals are set, the movement of trains is performed with unsealed auxiliary buttons.

In the normal (released) position of the apparatuses, all the relays are without current and the rectifier is idling.

When translating the switches of station A to the position “departure and station B to the position“ reception, the following circuits take place;

1) Linear circuit - from plus kenotron rectifier 14 station B, through the contact plates of switch 1, the contacts of the key, the wand 12, the current passes through the line along the wire a. From the wire, the current enters station A on the contact plates of switch 1, passes through the closed contact of the blocking relay 6 line, through the winding of the linear relay 4, and returns via wire b back to station B.

At station B, the current from the wire b passes through the winding of the linear relay 4, through the closed contact of the blocking double relay 6 linir through the contact plates of the switch 1 to the negative of the rectifier 14.

With the passage of current, the linear relays 4 stations A and B trigger and close the power supply circuits of the blocking relays of line 5 at both stations.

2) The blocking relay circuit of the line of stations A and B - from the plus of the rectifier through the closed contact of the linear relay, the winding of the blocking relay and further through the closed contact of the pedal relay 3 to the rectifier minus.

As soon as the blocking relay of the line has worked, it starts to receive power through its own closed contact along the circuit: from the plus. The receiver is connected through its own closed contact to the winding and from the winding through the closed contact of the pedal relay to the minus of the rectifier.

At the same time, the linear relays are disconnected from the line by the contacts of the blocking relay, and re-allowing the train to depart, no station can give each other until the unlocking of both devices.

3) The circuit of signal relay 2 of station A receives power through the closed contact of the blocking relay of the line. The current from the rectifier plus passes through the contact plates of the switch /, the closed contacts of the blocking relay of line 6, through the windings of the signal relay and the closed contact of the pedal relay 3 to the rectifier minus.

Immediately after triggering, the signal relay receives power from the rectifier plus, through the contact plate of switch 1, its own closed front contact, relay coils, the closed contact of the pedal relay, and the minus rectifier.

When the alarm relay triggers, the relay plates switch the output traffic light from prohibiting to permissive and turn on the power meter.

4) The power supply circuit of the blocking relay of station B receives power from the rectifier plus through the contact plate of the switch, the winding of the blocking relay of the signal, the closed contact of the pedal relay and the minus of the rectifier. After the signal is triggered, the blocking relay of the signal receives a second power supply circuit from the rectifier plus, through a switch contact plate, a closed own contact, through its own winding, a closed contact of the pedal relay and a minus rectifier.

After the blocking relays 6 have triggered, contact 20 will open the signal relay circuit and thereby block them.

Both devices will be released only after the pedal relays have triggered, which, by opening the supply circuits of the blocking relays 6, will return them to the normal, de-energized position.
