Description

The known devices of linear-track semi-automatic blocking for single- and double-track sections of railways, containing route-control devices at the station, are complex in design and do not provide sufficiently safe train movement.

The proposed device is simpler and improves traffic safety due to the fact that the inter-station sections are equipped with track circuits; The inter-station communication line wire includes polarized relays, the number of which is equal to the number of isolated sections, and two-circuit relays are connected through their contacts, and a transmitter and a current source are installed at the station to power the rail circuits.

FIG. 1 shows an electrical diagram of a station control panel; in fig. 2 is an electrical diagram of a linear-track semi-automatic blocking of the “even side of the station”.

In the station on duty station, there is a security panel for the type of crossing signaling containing a white, red and green light bulbs, a notification call off button and a recovery button for each side of the station.

The three-way button is used to restore the blocking system after canceling the route of departure or after returning the domestic train from the haul. This button also turns off the output signals.

When the stage is free, the light bulbs on the panel are not hot. A green green light controls the open position of the output signal, the red light indicates that the stage is occupied by an oncoming train, the white light is occupied by the train sent from this station.

On the route-control devices of the switch posts 2 and 5, the buttons for the recovery of the haul, the voltage-reducing buttons and the wrench-key device are installed.

The domestic train is sent when the output signal is open and the key-wand is handed to return the train from the haul.

Driving is restored by the station attendant with the participation of a switchman at the station towards which the utility train was sent or towards which the departure route was canceled with the output signal opened.

The display of free span is automatically made after the train arrives in full strength at the receiving station.

A call call at the departure station rings when the train enters the sectional track section. The bell is turned off; pressing the button.

Upon arrival of the train to the next station, the bell rings; It is turned off by setting the button to the normal position.

At the receiving station, the call rings when the output signal from the departure station opens, and turns off by pressing a button. Upon the arrival of the train at the station and the release of the sectional track section, the bell rings, which is turned off by setting the button to the normal position.

The drive between stations is divided into isolated sections. When used as a traveling relay, the P1P1-0.3 tire is up to 2.6 km in length, and for the traveling relay of type HP2-2 - up to 1.5 km.

At the boundaries of the plots, small battery wells are installed, in which the power sources of rail circuits are placed. Into a wire of a train interstation connection at each point is switched on by a linear relay. The relays are normally de-energized by connecting the poles of the same name with station linear batteries. The polar contacts of the linear relays, depending on the position, and the neutral contacts, when the relays are turned under, connect the traveling relays and the batteries to the rails, and when de-energized they turn them off.

Thus, with the linear relay energized, the track circuits will be energized when current pulses are received from the station set to receive.

In another embodiment, the line relays are not connected to the inter-station communication wire on the stretch, and a separate battery and track relay are installed for each end of the track circuit. The inclusion of a relay or battery in a rail circuit will depend on the arrival of an initial pulse from a station installed at the reception.

At the station, output traffic lights (lens or projector) are installed, and semaphores or traffic lights are used as input signals.

With a free stretch on the panel in the room on duty control lights are dragged. The control relays 4 are under the current. In the relay m of the output signal cabinet, the counter-current relays 5 and the relays 6 are under current, the other relays are de-energized.

The linear relay 7 is without current due to the connection to the line of the same poles of linear batteries at adjacent stations. For the departure of the train, the preparation of the route is done in the established order. The signal is opened when the route block is unblocked at the switch station with simultaneous blocking of the block at the duty officer.

When the blocking unit is blocked, the locking contact breaks the circuit of the same pole of the linear battery, and the linear signal relay 8 is connected to the linear circuit via one of the windings. Through the windings of the linear signal relay, a grounded pole of a linear battery (earth) is connected to the line.

As a result, the linear signal relay and the linear relays at both stations and on the stretch are under the current of a certain polarity, appropriate for sending the train from this station. The normally polar contacts of the linear relays correspond at one station for sending, at the other for receiving the train.

The lp.no-signal relay 8, energized, shunts the contact of the block mechanism in the linear circuit pnrtJbHbm, excluding the breakdown of the circuit when the block key is accidentally pressed. In addition, contact 9 prepares the power supply circuit for the second winding of the relay 8. At the receiving station, contacts 10, 1-1 of relay 12 de-energize the anti-relay relay 5, contacts 13, 14 of which are opened after the discharge of the capacitor connected in parallel to the winding. At the same time, an auxiliary linear relay 15 is energized, which bypasses the contact J of the linear circuit and turns off the negative battery. Pin 5 also turns off the minus of the linear battery in the line-signal relay circuit 5.

The linear relay 12, by its polar and neutral contacts 16 and 17, includes an antenna transmitter, which creates a circuit for sending current pulses to a rail circuit. Thus, when the train leaves the adjacent station at the receiving station, relays 12, 15 and 18 are energized.

When the track relay is energized at the first overhead track section, subsequent track circuits will operate in sequence through the contacts. As a result, a repeater track 19 will be turned on at the departure station, through contacts 20, 21 of which a circuit is created for the signal relay 22 depending on the prepared route. Relay 22 will receive firing through the polar contact of relay 12 and the front contacts of relay S, 12 and 19. The front contacts of relay 8 and 19 are bypassed by sequentially connected contacts of relay 22 and 23. The front contacts of relay 22 at the exit traffic light turn green.

When setting the departure route, the sectional track relay is energized through the front contact of the relay 22.

A 1-1 pulse track relay 24 is switched on via the polar and front contacts of relay 12. A repeater track relay repeater 19 is turned on according to a typical circuit.

When the relays 22 and 23 are energized, the relay 5 is de-energized at the dispatch station. With its contact, relay 5 breaks the circuit with a linear and linear signal relay. As a result, the circuit of the impulse traveling relay at the station, the traveling relay and the traveling batteries on the stretch is broken.

An anti-repeat relay can only be energized after the actual train is reached at a nearby station.

When the sent train enters the track section, the relay 23 is de-energized, which by its contacts breaks the power supply circuit of the relay 22. The relay 23 can be energized again to be sent only upon the next excitation of the relay 23 after a complete blocking cycle. Thus, the sectional relay 23 is also anti-repeat -when shipped.

Upon entering the train and receiving station, the sectional relay 23 is de-energized, which was energized by the contacts of the reception handle in the route control device. Through the rear contact of the relay 23, the actual arrival of the train 25 will energize when the input signal is open, which is detected by the missing contacts of the relay 6.

Relay 25, when energized, prepares a circuit of anti-repetitive relay 5, eliminates the POSSIBILITY of excitation of relay 15 and additionally bridges the contacts of the receiving handle in the power supply circuit of relay 23. After releasing the track sectional section from the train, relay 23 is excited and after closing the input signal - relay 5. the contact includes a linear wire plus a linear battery, causing all the linear relays to be energized. The power supply of the track circuit is switched on from the receiving station to the inbound circuit through the contacts of the pendulum transmitter and the linear relay. At the departure station, the linear relay 12 and the repeater track relay 19 will be energized, as a result of which the relay 5 will be energized and the circuit will return to its original position. The state of the station is controlled by the relay 4, which is under a certain polarity current after the actual arrival of the train. A switch of the relay 25 serves to obtain the control of the excitation of the relay 5 at the departure station, which, having excited, connects the station battery of the same polarity to the linear circuit.

The relay 4 and the opening of the output signal is energized by a reverse polarity current through the rear contact of the relay 5 and the front contact of one of the signal relays. In this case, a green lamia lights up indicating the opening of one of the output signals. After the train enters the track section, relay 22 de-energizes, breaking the relay circuit 4, which releases its neutral contacts, indicated on the dashboard by ignition of white light, which indicates that the haul was sent by the dispatched train from this station.

To restore the haul (system operation) after returning the domestic train from the haul or, if necessary, to send the oncoming train after canceling the route with opening the output signal, the duty station of the receiving station simultaneously presses the stop buttons 26, which causes the relay 25 to energize the lower winding. The relay 25, having excited by its contact, closes the power circuit of the relay 23. Further, the circuit operates in the same way as the train arrives. The freedom of the haul is checked both on arrival of the train at the station and on departure. When sent simultaneously with the linear signal relays 8, all the linear relays of a certain polarity corresponding to the given direction of movement are energized.

As a result, pulses are sequentially sent from the receiving station to the track rail circuits, and after energizing the track relay, the departure station is the circuit for the signal relay, which becomes self-locking, breaking the circuit to its anti-switch relay. The latter breaks the linear chain.

At the receiving station, the counter-repeater relay 5 is de-energized when the linear relay is energized. Thus, the "request from the sending station is made by the line wire, and the clearance from the receiving station is made via the track circuits.

With the full arrival of the train, the check is carried out from the reception station by the line wire and by the track circuits.

At the receiving station, the anti-repeat relay is energized after the train arrives, and in the sending station, the anti-relay relay is energized after energizing the linear relay and the repeater of the pulse relay. Line wires are normally under the voltage of the same poles of two batteries of adjacent stations. Under current, the line wires are at the time of sending a message and giving a signal of arrival. In order to eliminate possible interference from station batteries having a voltage difference, a repeater track relay contact is connected to the linear circuit, which is bridged by the contact of the linear signal relay. The rear contact of the repeater track relay in a linear circuit closes much later than the front contact of relay 5 closes upon arrival, as a result of which the front contacts of the linear relays will be released. After the train has departed, the linear circuit at the reception station is disconnected from both the ground and the battery, which excludes the possibility of dispatching the oncoming train if the linear wires are damaged.

At the ends of isolated sections of the distillation circuits, the contacts of the linear relays connect, depending on the direction set, either the battery end or the relay. Upon receiving the power of the first track circuit from the receiving station, all track circuits are energized sequentially, since the track circuits are powered via the track relay of the leading part. It is also possible the variant of the distillation schemes, when the track relays are normally included in the track relays through the rear axle of the front relays. When one of the relays is energized from the receiving station, a battery is turned on in the track circuit, which excites its track relay along the track circuit. The latter connects the power of the next track circuit. Such a process continues until the relay in the departure station is energized.

In this embodiment, there is no need to install a linear one) at each distillation point.

The power supply of the station equipment comes from local sources of alternating current. In case of unstable power supply, searchlight signals with flashing lights are used.

On the stretch, short-term power supply of track circuits is carried out from the elements of the MOE or VD.

In the presence of a crossing signaling signal on the span, the control of vacancy is carried out by two wires, in which the contacts of the traveling relays of the crossing and the contacts of the "linear relays" are included.

The described device linear-track semi-automatic blocking can be used in railway transport.
