Description

Devices are already known for electrically centralizing arrows and signals, in which all the necessary dependencies between the transfer handles are carried out exclusively by electric means. Similarly, "devices are also known in which the control transfer handles are installed on the index plan of the paths, arrows, and signals of stations, so-called scoreboards.

The present invention relates to a device for electrically centralizing arrows and signals with translation devices located on or under the station's indicator plan showing the position and condition of paths, arrows and signals. The invention is because in order to break, in appropriate cases, the starting current feeding the starting electromagnetic devices of switch actuators, self-holding relays are used as switching relays of the switch unit; the circuit of the switch relay is conducted through the contact of the route relay, whose circuit,

In turn, it is conducted through the contacts of the control signals of the relay of the routes, in which this arrow is involved.

The proposed device allows the transfer of the handle during the whole time, but the movement of the needle or the opening of the signal is possible only if there are conditions permitting the transfer, i.e. traffic safety is maintained complete. At the same time, the agent transferring the handles is constantly informed by the corresponding indicators on the scoreboard and at the handles about the position and condition of the arrows and signals. The control unit is made in the form of a light panel, depicting paths, arrows and station signals. Transfer switch knobs are located on the scoreboard itself against the respective arrows or below the scoreboard arrows. For control of the signals, bell-type push buttons are proposed, which, after being pressed, are automatically returned to their initial position by a spring. These buttons can also be located directly on the scoreboard, for example, at the bases of the signals or outside the scoreboard. A part of the required relays can be installed inside the board, a part is moved to a separate relay room. The position of the arrows can be indicated on the scoreboard only by the lamps located at the scoreboard arrows, for example, of different colors or indicating plus and minus on them, or by means of reassembling the arrows giving a connection in one way or another. In the same way, an indication of an ongoing arrow transfer can be provided by a special lamp. A separate lamp may indicate the inadmissibility of the translation of the handle at the moment. The position of the signal can be indicated on the display by changing the color of the indicators, lighting or extinguishing the latter. Occupation or absence of isolated areas is indicated on the scoreboard in one of the usual ways. In the description below of the device and its operation, the station is taken as an example with complete isolation of the paths; however, the proposed device can also be used on stations with only isolated switch sections, as is done in conventional installations.

In FIG. 1 shows for the instrument one side of the station with two arrows and three light signals. Accordingly, under the display there are arrow knobs, and on the display there is a signal button (Fig. 2).

The switch electric actuator is equipped with a starting electromagnetic device in the form of an associated system of neutral and polarized electromagnets or in the form of a combined relay with neutral and polarized crust. Two starting drives 7 and 2 (Fig. 3) are suited to the starting device, through which current is supplied to drive the starting device. The direction of the current in these wires changes when the handle is translated and depends on the position of the contacts which are closed by the handle in its extreme positions. From the automatic switch of the switch actuator, go to the control wires to the control polarized switch KR at the station. For

Power supplies to the drives can be applied either to the trunk system of two supply wires, or to a local power supply with current sources installed directly on the drives themselves. In the isolated switch and track sections are included, in the usual way, the traveling relay PR. The transfer switch knob, in addition to the above contacts, also has a contact that closes in the middle position of the handle.

For each switch handle, there are two self-retaining (blocking) relays: an SBR switch and a routing ICBM. An SBR switch relay (Fig. 4) is connected to an electrical circuit via a UP track switch contact. An isolated switch section, closed with a free section, through an MBR route relay contact, closed when the latter is in an excited state, and through a handle. In addition, the last contact was switched on at the last contact, drawn through its own contact of the relay. In the starting wire circuit there is a contact of the relay. If the arrow is not occupied by the composition and the routing relay is energized, then when the handle is moved, it closes, approximately in the middle of its stroke, the contact in the CBP relay circuit and the latter is excited (if it has not already been excited) and closes the contact in the starting circuit. When the handle is brought to the end, the a and 6 contacts in the starting circuit are switched, thereby changing the direction of the current in the starting device and the last, by operating, sends current to the drive. It is obvious that the transfer of the handle at the time when the arrow was occupied or installed in the route (i.e., the route relay was not energized) cannot entail the transfer of the arrow, since either the relay contact PR or the contact relay MBR in the circuit of the switch relay. However, the release of the site and the excitation of the PR relay or the release of the route and the excitation of the relay of the ICBM will not entail an automatic translation of the arrow in whatever position the handle is located. In fact, when the handle is in the middle position, although the RRF relay is energized, the contacts of the a and and & in the starting circuit, when the handle is in the extreme position, its middle position will be open, the relay will not be energized and the starting circuit will be interrupted by the contact of the last relay. The second relay route MBR is also a self-retaining (blocking) relay. It is normal when the route is not installed under TOKOJM (Fig. 5). It is turned on through the contacts of the control signals of the CC, closed with closed signals, and through its own contact closed when the relay is energized, parallel to which the circuit is connected, conducted through the open contact of relay / 7 / of the isolated switch section. When the signal is opened, all the route relays of the arrows protected by this signal are deprived of current and their contacts break the circuits of the SBR switch relays. The excitation of the new routing relays takes place under the condition that the signal is already closed as the train hits the respective isolated arrow sections, which leads to the closure of the contacts of the PR relay in the MBR relay circuit. However, the circuits of the SBR switch relays will be open at the same time with the contacts of the same PR relay while there is a train in the respective turnout. Thus, the arrows are released as they are passed by train, i.e. the so-called route-sectional closure of the arrows is carried out without any additional relays and devices, only by the respective use of the same two SBR and MBR relays and a special circuit for their activation.

As mentioned above, the signals are controlled by buttons, which are returned by the spring after pressing. When the button is pressed (Fig. 6), the self-holding signal controls the relay BORO, which, after excitation, receives power through its own contact shunting the signal button, is energized. Otherwise, the control signal relay circuits are arranged in one of the usual ways, for example, by passing them through the relay contacts, controlling the hostile signals, the control relay contacts

shooter, contacts of the track relay sections, when the train enters the signal should automatically close

etc.

If there is an automatic blocking on the adjacent spans, the proposed device for centralization is extremely easily and simply linked to the blocking by means of the device depending on the signal readings from both the linear auto-lock relay and the control of the BURS relay signals. Since the path and arrows are still isolated when the block is automatically locked, the proposed centralization device is greatly simplified. In the absence of an automatic blocking, the complete isolation of the paths can be avoided by arranging only arrow-isolated areas and isolating a preliminary section, which is supposed to close the signal.

In the presence of automatic blocking, the proposed device with some addition allows the station and signals to be converted to automatic action. Addition, this is reduced to a circuit device, a parallel button chain, and a relay contact circuit of its own, shown in FIG. 6 dotted line. In this parallel jumper there is a normally open contact OK bypass. If it is necessary to leave the station unattended and transfer it and the signals to automatic action, it is enough to set the corresponding arrows along certain paths, to translate the corresponding bypass lever, i.e. Close contact OK. Since the signal chains depend both on the linear auto-lock relay and on the control signals of the BURS relay, when the train passes the signal, the latter automatically closes (depending on the track relay contacts in the BURS relay circuit) and automatically opens only after the train passes station (depending on the linear auto block relay). It should be noted that the transfer to automatic action is possible both on the main path and on any side track (depending on the installed arrows).

Since, when translated into automatic action, the arrows are locked due to the opening of the route relay circuit by the relay contacts BURS, and the circuit of the switch relays-relay contacts, in order to be able to transfer the arrows to the train brigade, if necessary in maneuvers, special local levers are used that are installed in locked cabinets or at the shooter. The local lever is provided with the same pins as the normal switch-over handle, and a contact that is closed in the middle position of this local lever is connected to the switch circuit of the CBP switch parallel to the same contact of the transfer handle. The same contacts and 6 extreme positions of the local lever in the starting circuit are connected in series with the same contacts a and b of the transfer handle. Such a device is applicable, of course, during normal operation of the station.

The contact of the auxiliary sealed button bk is included in the circuit of the route relays of the ICBMs (fig. 5), provided for the purpose of artificially releasing the route if necessary.

The subject matter of the invention.
