Description

Devices for blocking alarm for double-track railways using a single wire are known. Equally known and widely used in practice are such devices for blocking signaling, in which, instead of the usual block mechanism, the so-called electrical circuit of an alternating current with automatic blocking is used. The invention according to the invention 1e relates to a device for single-wire blocking signaling for double-track roads with the use of such circuits and consists in that the circuit, in which the arrival block mechanism is connected, is conducted through the contacts closed by a crust of a polarized electromagnet connected to the departure block mechanism; the latter is made in the form of an electrical circuit with alternating current with automatic blocking, the bolt rod of which carries contacts serving to change the direction of current in the specified electromagnet.

The drawing shows a schematic equipment of a single terminal station. In this device, as a polarized electromagnet, the contacts of which are included in the circuit of the block mechanization with 184 .-,

be used electromagnetic shutter type wands.

In the normal position of the device, the output and input semaphores are unlocked, the software sending mechanism is unblocked, and the software block arriving PP is blocked. Block mechanisms operate on alternating current sent by the inductor.

To clarify the operation of the device, consider the departure of the train from station A to station B.ch.

If desired, send the train to station A opens the output semaphore in the direction of station B, which then, after the train leaves, closes. To call station B by a call, the call button is pressed and the inductor knob is rotated, at which the current from the inductor comes through contacts / 5, 12 and the call button is in line to station B, from where the earth returns through contacts 7, - /, 9 w JO to the inductor .

At station B, the current from the terminal enters the call button and passes through the call, contacts 5.4, the software block and the electromagnet 75 to the ground. At the same time at station B the call rings, and the software block and the electromagnet 75 do not work.

After this, the station I, by pressing my button, gives a call back. Then station A presses the software key-button, as a result of which the block-mechanism automatically locks and locks electrically on the semaphore. In this case, the contacts / 2, / j and I 10 are opened and the contacts 13,14 and 10,11 are closed, which leads to a change in the direction of the constant, pulsating current sent by the inductive TOpiOM to the line.

When you subsequently press the call button on station A and rotate the handle of the inductor, the current from the positive and the Inductor comes through contacts U, 7 / and 12, the button, which calls the line B to station, from where it returns via contacts 14, 13 B minus the inductor. At the same time, at station B, the current from the line enters the call button and through the bell, contacts 5, 4, the software block and electromagnet 75 passes into the ground and to station A. At the same time, the polarized electromagnet 15 is activated and its measles is turned, the contacts are closed 7, 8 and in the eyeglass color from white to red. As a result, the block mechanism of the PP is connected to the local inductor circuit and closes the following circuit: brush and inductor, block mechanism PI, contacts 2, 1.8, 7, ground to bus, push buttons, inductor brush 02. According to the received signal, the person on duty at station B rotates the inductor knob, as a result of which an alternating current passes through this circuit, under the action of which the block mechanism at station B is unblocked. Thereafter, an input semaphore is opened at station B. Upon arrival of the train at the station. the electrical circuit is unblocked and the input semaphore is closed.

The station attendant on duty B presses the block button of the IP mechanism block and rotates the inductor knob; at the same time the current from the brush //

the inductor passes into the block mechanism / 7/7 and through the contacts 2, 3, 5, the call button and the call to the line to station A, from where the earth returns to the call button to the brush / 32 inductor. As a result, the block mechanism JlH of station B is blocked.

At station A, the current from the line enters the call button and through the bell, contacts 5, 4, the software block, the 7.5 electromagnet passes to the ground and to station B. The block mechanism –7O of station A is unblocked, so that it is again possible open the output semaphore and release the train

Thus, the entire device for the given direction of train movement, i.e. from station A to station B comes to its original position. The movement of trains in another direction, i.e. from station B to station A is carried out similarly to the above.

The subject matter of the invention.

A device for single-wire interlocking signaling for double-track railways using conventional type block mechanisms and alternating-current AC electrical circuits with automatic self-locking, characterized in that a polarized 75 electromagnet is connected to the circuit of the dispatch mechanism and is passed through electromagnet of a certain direction, contacts 7, 8, through which the block of the block mechanism is led to arrive, and the contacts are used to change the direction of the current in the electromagnet Kty, placed on the crossbar rod of the sending mechanism, made in the form of an electrical circuit of alternating current with automatic blocking.
