SU17361A1 - Device for track locking signaling type Siemens and Galske - Google Patents

Description

The existing two-wire blocking alarm devices have the disadvantage that if the blocking wires communicate with each other or when they communicate with another wire, or if the grounding device B is broken or external to the device, a false arrival signal can be received, which makes it possible for the train to depart. distilled To eliminate the effects of these cases, a blocking scheme is proposed here, in which, due to the addition of some contacts and the elimination of the resistance of the electromagnets included in the apparatus circuit, and due to the general redesign of the interconnection of all parts of the unit devices, it is also expected to enable interlocking telephones via a two-wire system.

In FIG. 1 shows the wiring diagram of the block devices at the end station and at the two intermediate ones; fng 2-circuit phone switch.

In the case of communication between each other, the blocking wires that occurred during the movement of trains in both directions of the haul, when one of them arrives at the station and when a signal of its arrival is given, the current from the inductor reached the place where the wires were communicated , will return back to its same inductor, pass through the electromagnet of both block elements, and thereby unlock the next block at the same station, the sending, i.e. there will be a false arrival and, at the same time, the possibility of sending the train to a busy haul. In order to avoid this, according to the invention, a device (Fig. 1) offers additional breaking contacts fi, each of which is connected between the line wire and electromagnets of the adjacent block mechanism, so that when the button is pressed, the current, when the line wires are connected to each other, cannot return to your inductor through another unit of the same station, because contact K will be open at this time.

In the existing schemes, the grounded conductors from the contacts go to the common bus, which, in fact, is connected directly to the ground. Therefore, in the event of a broken ground wire, there is a lack of earth at this station, and therefore both cranks are connected to each other, which will cause the operation of both block elements and may cause incorrect signal transmission. According to the invention, each block mechanism is proposed to be grounded independently, so that in the event of a grounded break, the action of the corresponding block of blocks is terminated and the supply of the wrong signal does not occur.

In the case of a blocking wire with another wire through which alternating current flows, the consequences of such a message, like the previous one, will cause a spurious signal with all bad consequences that can be eliminated by directing alternating current to the ground and not to the unit what is achieved, according to the invention, by the fact that a discontinuous contour is put on the transom rod, intended to short circuit in the unlocked state of the block; the line-to-ground wire is then connected directly, so that if the locking wire is connected to the wire that carries the alternating current, all the current goes to the ground.

In the blocked state, the contact is opened and the unit will be included in the circuit, and in the case of communication with an extraneous wire, although a false signal will be sent to the train, but there will be no danger to the trains.

In the existing scheme, when the signal from one of the stations is not blocked, other stations adjacent to it cannot give a bell signal, since the latter is fed through contacts that will be in the open position in the non-locking state. According to the proposed scheme, independent wires are used for the bell signal, connecting both the inductor brushes and its case with the bell button, the block mechanism’s contacts, as a result of which the blocking does not reflect at all on the work of the calls, and therefore the phone same station.

Under the existing scheme, switching phones via a two-wire system, as

reporting two linear wires between them, with insufficient attention to the matter, that is, when sending a blocking signal when you turn on the phone at a nearby station, it can block the next block. According to the proposed scheme, this is eliminated thanks to the presence of additional contacts, even if one station turned on its phone and the friend mistakenly sent a blocking signal, no action will occur, because the other wire along which current could return to the inductor, it will be separated by the open by pushing a button contact Ii.

Due to the use of a special switch (Fig. 2) for telephone conversations, it is not possible to set the springs to "direct", and at the same time it is possible to turn on the telephones via a two-wire system, and for negotiations with the right or left station the switch must be set respectively to the right or left .

In the existing circuit, when the keypad button of a single-wire blocking telephone is pressed and the blocking signal is simultaneously sent from the neighboring station, the system can be put into a state of non-opacity, which runs according to the proposed circuit, in which telephones are switched on via a two-wire system.

The subject of the patent.

1. The device for the track blocking signaling of the Siemens and Galske type ... is characterized by the fact that in the block mechanisms additional discontinuous contacts K are arranged, each of which is connected between the line conductor and. the electromagnets of the neighboring block mechanism, which contacts are intended to prevent the train departure on the busy path in case of communication between each other of the linear wires.

2. In the case of the described in p. 1. device, the use of an independent grounding block for each unit.

3.When the device described in pp. 1 l 2 is used, the device is installed on the plug-in rod of the equipment unit.

an If A contact, intended to short-circuit the electromagnets of the designated block mechanism and directly connect the linear conductor to the ground, with the aim of preventing dangerous consequences from communicating the designated conductor to a constant AC source.

4. When the application is described for the device described in the PP.

the signal of the self-conductor wires, which are like inductor brushes, - so its case with the bell button, mine the contacts of the block mechanisms.

5. With the device described in clause 1, the use of a switch allows the phones to be turned on via a two-wire system and prevents the possibility of setting the wires to direct.
