SU39196A1 - Device for electrical interlocking of arrows and signals - Google Patents

Description

The basis of all existing route setting systems, regardless of the type of centralization, is the mechanical interlocking of the arrows after their installation in the appropriate position, with the arrows being locked, usually all at once or in groups, in any sequence, after which the corresponding control opens the signal.

The electrical systems used (according to the conventional terminology - relay) -centralization require very complex circuits and a large number of relays for their implementation. The goal pursued by the author of the present invention is the implementation of this kind of centralization device with the use of a minimum number of relays and a corresponding simplification of the circuits. The centralization device system described below is based on the principle of automatic, individual-sequential closure of the arrows in the installed route, according to which the group route switches are used in the route to be installed, which are installed in the quantity of one at each end of the station and unite the group of hostile routes, and the arrow locking relays locking the arrows and controlling the signals; For the implementation of reception routes, one reception relay was applied to a group of hostile routes, connected via the switch-contact relay and track relay contacts.

The general sequence of operation of the described device is as follows. The signalist sets the corresponding position of the arrow and presses the route-signal button. In this case, one by one all the arrows of the route are locked in, starting from the arrow at the exit to the stage and ending with the arrow at the corresponding path. Following this, the output or input signal opens, depending on which way the button was pressed (right or left). This is followed by the passage of the train route. Regardless of whether the train is being received or sent, after passing the head of the train past the corresponding signal, the latter closes and, as the arrows are released, the last one by one is unlocked. Thus, the signal is closed and the arrows are unlocked automatically.

FIG. 1 shows a part of a station having five tracks, four arrows, one input and five output signals; in fig. 2 shows the scheme of switching on the GZ relay of the group lock arrows, where the MK-route-signal button, GZ is its own contact of the GZ relay, PR1-contact of the track relay of the first arrow on the side of the haul, / 7P2, PRZ, etc.-contacts of the relay relays plots adjacent to the dispatch path m. FIG. 3 and 4 depict the switching circuits of the locking switch relays, the circuit of FIG. 3 is used for arrows adjacent to the span; if the arrow in question is followed by two arrows, then the diagram in FIG. 4. In FIG. 5 given the scheme of inclusion of the relay I / 7. Its purpose is to control the input signal and lock the output signals. It is activated through the circuit of the SZ and KR contacts of the arrows adjacent to the receiving paths, the contacts of the PR of the receiving paths and through its contact P / 7, which is shunted by the contact KR, the signaling button. The latter is located on one handle with a signaling contact and closes when the handle is turned in one particular direction. FIG. 6 shows an input signal activation circuit.

Here RK is a red fire relay; RZ, P3J and P32 relay permit lights. As can be seen from the diagram, the signal is controlled by the relay C3, CR, PR and P / 7, and there are absolutely no special signal-controlling relays.

Below is a description of the operation of the circuits when setting the reception route to path 1. To carry out this route, after the arrows are set to the appropriate position, the route signal button is pressed to the right (along the train). This closes the contacts MK (Fig. 2) and KP (Fig. 5). When the contact is closed, the MC receives power from the GZ relay, which, having drawn its own measles, is switched on to the supporting circuit. This relay, when triggered, deprives the power supply of the relay NW and the arrows / and 2 turn out to be locked.

When relay C32 is activated, the power supply circuit of relay P / 7 closes along the path; contact C32, contact KR2, controlling the position of the arrow 2, and contact PR1 of the track relay of the 1st path, contact CZ of the signal close button, on the assignment

which will be discussed below, relay P / 7 contact KP, reverse pole of the battery. Relay P / 7, energized, closes on the supporting circuit through its contact P / 7 and produces the following: switches its contacts to the input signal circuit (Fig. 6), turns off the shunting of wires to the permission lights and switches the power from the red lamp to the yellow one through pins S3 / and P / 7 /, but red will go out only if it turns yellow. This is provided by the control relay contact / 737 in the power supply circuit of the red lamp. If the train is taken to a side track, then a second yellow lamp turns on through the contact point KP of the corresponding switch (in this case, the first). In the pass-through mode, through the RZ contact of the control relay of the permissive fire of the corresponding output signal, the green light on the input signal turns on. If it is necessary for some reason to close the input signal, then this is produced by the КЬ button in the P / 7 relay circuit (Fig. 5). At the same time, relay P / 7 is deprived of current, releases its measles and, by breaking the supporting circuit, switches on the red lamp on the signal. To re-open, press the KP button again.

The head of the train, passing by the input signal, will bypass the track circuit / 7P /. At the same time, the relay / 7P / will lose current and, releasing its measles, will produce the following: 1) turn off the permission light on the signal and turn on the red (Fig. 8); 2) opens the power supply circuit of the GZ relay (Fig. 2), which, in turn, opens the supporting circuit and prepares the switching on of the NW relay without current; 3) turn on the power supply of the SZ / relay, which is taken to the supporting circuit and contacts the / 7P / bypass contact in the power supply circuit of the red signal lamp (Fig. 6). Entering the second arrow, similarly, the C32, relay C32, already prepared by the contacts of GZ and SZ / circuit, will initiate through the contact / 7Р2. thereby removing the current of the P / 7 relay, which returns to its normal position. The arrow / is released only when the tail of the train leaves the rail section of this arrow and PR1 doesn’t have its own measles. Similarly, the release of the arrow 2 occurs. In this way, the train, as it proceeds sequentially through the station, will automatically close the signal and release all the route arrows, one after the other. In exactly the same way as the reception route, the departure route is established. In this case, the route and control handle will need to be turned to the left. At the same time, just like when receiving, the GZ relay circuit is closed by the contact of the A1K handle, the corresponding arrows are also locked.

For a given departure route, relay P / 7 does not turn on and does not participate in the operation of the circuit.

To artificially close the signal, a button with short-circuit contacts was used in the GZ relay circuit (Fig. 2) and in the С32 and СЗЗ relay circuits; on the same button, there is a short-circuit contact, which is included in the P / 7 relay circuit (Fig. 5). The short-circuit contacts are placed in the NW chains of all the arrows adjacent to the dispatch path. When this button appears, the GZ relay loses current, and the corresponding Blow, and the arrow (second, third or fourth) opens, due to the activation of the NW relay, which closes the signal. To re-open the signal, you need to press the route-alarm button.

For artificial uncoupling of the route, a button is applied, when pressed, the signal will be closed automatically. KO button has contacts in the circuit of the GZ relay (Fig. 2) and in the circuit of the NW relay of all the units. When this button is pressed, the current of the GB relay is lost and all the GS relays are energized.

The subject matter of the invention.
