Description

An automatic blocking unit is known. For single-track semi-automatic blocking, containing blocking track blocks, side traffic lights, track relay, signaling, anti-repetitive and consent relays, instruments for fixing train tracks and for monitoring the state of track blocks, such as rail circuits. track relays.

The proposed checkpoint differs from what is known in that, in order to increase capacity, while observing the established order of passing trains by single track with a checkpoint and to simplify the scheme of connecting the checkpoint with adjacent stations to an inter-station linear circuit, sequentially through the relay contacts, detecting the fact of train chasing, a polarized relay of the direction is included, the contacts of which are included in the excitation circuit of the even and odd track relay, which control the signal relays, and oh from adjacent stations interoffice circuit through relay contacts of the auxiliary relay track origin and semiautomatic lock included additional relay which is triggered by the signals coming from the checkpoint at the instants prosledovani train for passing light, and unlocking relay track origin and

the relay of the villa agree, thus ensuring the possibility of filing a blocking signal to the adjacent station for sending to the checkpoint of the next train.

FIG. 1 shows variants of the general scheme of traveling devices; in fig. 2 shows a circuit for switching a polarized relay into a linear circuit; in fig. 3 is a diagram of switching devices

train tracking; in fig. 4 is a circuit for activating a neutral relay at the station A adjacent to the checkpoint.

The traveling device of the automatic checkpoint (see Figs. 1 and 2) includes passing traffic lights H to N to enclose block segments of the haul and two short (25 m) insulated road sections In and 2n to fix the train track for traffic lights.

In order to control the state of the blocking blocks, the stage is equipped with rail circuits consisting of one-way (towards the block-post) connected one-way broadcasting of blockpieces of OHG-a, b, ..., p and PNP-a, b, ..., and

(see Fig. 1).

For the implementation of dependencies at the checkpoint (see Fig. 3), the HP directional relays (polarized) of the route IL / 70/5 and H POR, signal NDS and

track block state monitoring (track relay decoders) - NGPR and CHGPR. On the block station, track track SR and 2PR were used for fixing the train track, arrival of the PRD and PRP, auxiliary 1CHR, 2SCHR, SNAGN and OCHGPR.

At each of the adjacent stations, not counting devices related to the relay semi-automatic interlocking, the relay circuit of the PBPR and the NBPR is connected to the linear circuit of the latter. In addition, at the station, mounts are fixed for the arrival fixation of CPPG and NPFR and the auxiliary relay VCHPOR (VPPOR).

The automatic checkpoint works in the following manner.

In order to send, for example, an even train to station A from station B, the latter must receive consent for this, and therefore, the relay for giving consent to PDTM (not shown in Fig.) Should be initiated at station B.

At the moment of opening the departure traffic light at station B, the COVR auxiliary relay (not shown in Fig.) Will release its measles, through the rear contact of which the CTB transmitter (not shown in Fig.) Sends a current pulse to the rail circuit of the PPP block section. At the same time, a blocking signal is sent to the linear circuit through the rear contact of the COVR relay and the front contact of the CROP relay in the form of a direct current pulse of a certain direction, and the duration of this signal is limited by the slowing down time for the COOP counter-relay relay, which is about 0.7 sec.

As a result, at station A (see Fig. 4), the CCPOR relay is energized and blocked, and at the checkpoint it will excite and transfer its polarized switch to the HP direction relay (see Fig. 2). Due to the sending of current pulses to the PPP rail circuit, a dephaser of the PNP track relay will be excited at the checkpoint.

On; station A, as a result of energizing the relay, the CNCOR turns on the PDTSR relay (in Fig. 4 the contact of this relay is shown), by contacts of which the linear circuit switches to the circuit of the linear relay that has already been interrupted by the CNCOR contact, then, after a deceleration time, drops off (about 0.7 sec.) , will release its measles and auxiliary relay VCHPOR, through the contacts of which a relay of the emergency checkpoint block is connected to a linear circuit. However, at this point, the blocking signal of the transmission has already stopped, and therefore the PSTD relay is not energized.

At the checkpoint (see Fig. 2), as a result of driving the decoder of the CGPR track relay and moving the polarized core of the HP relay, the CCPOR relay is energized and blocked. If the forward track block of the NGP is free at the same time, the arrival of the last train from the checkpoint at the station was recorded by pressing

Buttons arrive at the CNC, then the alarm relay of the CSR will also be excited at the checkpoint, since station A will send current pulses from the station A side through the NMT transmitter to the rail circuit of the IGP block, and its front contact will be energized the excitation circuit of the CSR relay is closed.

As a result of the excitation of the CHSR relay, the power supply circuit of the anti-replaying PDPS relay is cut off, the relay releases its measles and is blocked in this position, due to the open state of the rear contact of the PNOR relay in its circuit. After that, the power supply of the TSR alarm relay is maintained through its own contact.

Thus, in the free state of both block sections of the route with the opening of the departure traffic light at station B, the corresponding traffic light at the checkpoint is also opened.

If the block-section enclosed by the traffic lights H is occupied by the train not arriving at station L yet, or if the arrival of the latter has not yet been fixed by pressing the CNC button, then with the traffic lights opening at station B, the traffic light H remains closed, as the decoder measles the NGPR track relay is released, its contact in the excitation circuit of the CSR signal relay is open. With the initiation of the NMT transmitter at station L (after the actual person arriving at this station following the block of the NGP train) actually arrives at the station, current pulses start to flow to the rail circuit of this block station, the GPS relay track terminator at the checkpoint (Fig. 2) sweeps, its contact closes in the circuit of the relay CSR, which is also excited, and the passing traffic light H opens.

At the moment the train enters the block section blocked by the H traffic light, the research relay track (in Fig. 2 the contact of this relay is shown) of the IGP rail circuit is shunted by the slopes of the rolling stock and stops working. The NGPR decoder at the same time releases its measles, turns off the alarm relay of the CSR, and the traffic light H closes.

With the train following the traffic light at the checkpoint, the follow-up relay (see Fig. 3) is energized, as a result of which, at the checkpoint itself, the blocking relay circuit of the PRPOR opens at the blockhouse itself and via the front-end contacts of the PRC along the linear semi-automatic blocking relay circuit (see Fig. 2) sends blocking signals about the train’s passage to station B, which sent it, and to station A, which is waiting for it.

In this case, at station L (see Fig. 4), through the tweet contacts of the auxiliary VCHPOR relay, the BSTP follow relay is energized and with its rear contacts it turns off the blocking power supply circuits of the PIVOR and ChFPR relays. The blocking circuit of the CSFR relay (from the local winding) is formed through the ChPPR rear contact, the ChFPR relay and the CCPR front contacts off the HMT transmitter, and the CCDR relay is released via the CCPR rear contact. This ensures that a blocking signal is sent to station B to be sent to the checkpoint of the next train.

In addition, the auxiliary ICFOR relay is energized via the rear CCP contact, the front CCP contact is bridged, the rear CSCBR contact opens a part of the local CWPR relay circuit and prepares the possibility of blocking it in the event of repeated excitation along a linear circuit, and due to switching off the transmitter, the BMT stops receiving. in the rail circuit of the block section of the NGP.

At station B, a linear relay of the HLR is energized with the arrival of a reverse current polarity current from the checkpoint block. As a result, the relay COVR and CCPR will be successively excited, making it possible to open the train departure traffic signal to the checkpoint, if they agree to blocking from station A. At the same time, the COOR rear contact (not shown) turns off the PMT transmitter ( Fig. not shown), as a result of which the flow of current pulses into the PPP rail circuit, PNP decoder (FNG. 2) at the block post releases its measles, is stopped, the front switch of the PDOR relay, which also releases an armature and its contact closes the rear chain drive protivopovtornogo CHPPR relay.

Through the rear contacts of the PNPR relay, the train tracking devices are turned on (see Fig. 3), so the latter with the PDUR drive being turned off (the 1SCHR 2SCHR relay and then the PRC release their cores) and the blocking signal is sent to stations L and B to stop.

After that, the blockhouse circuit is in its initial state, ready to pass the train in any direction.

However, at station A (see FIG. 4), the CSBR relay was excited, as a result of which the possibility of excitation of the linear train of the NLR, and, consequently, of the train departure, which followed the passing traffic light at the block post, is excluded.

The PDSM relay at station L is in the unlocked state, i.e., it is possible to initiate this by 1) pressing the corresponding KHOHKTJ and sending a blocking signal to station B to accept, and sending to the checkpoint of the next train.

is in the initial state and with the receipt of consent can send the next train to the side of the checkpoint. At the same time, with the opening of the output traffic light, as well as during the departure of the first train, they release the corners of the COVR and CHOPR relays. The CTB transmitter is turned on through the COVR rear contact, current pulses begin to flow into the rail circuit of the PPP block section, and the CPGP decoder is energized. At the same time, due to the slowing down of the CCPN relay, the blocking signal of the train departure is sent to the linear circuit, as a result of which the CCPOR relay is excited at the checkpoint and station L.

With the arrival of a previously sent train at station L, a relay is triggered to arrive at the PRC, which allows the person on duty at station L to disassemble the reception route, and by pressing the NCK button through the front contact of the relay, arrive at the PRN and contact PN13G1 (see FIG. 4), closed at the disassembled route receiving, initiate a relay fixing the arrival of the CPFR train. The latter, having brought measles, turns off the PBR relay with its rear contact. which, in turn, by releasing the measles, turns off the TCHPOR relay, as a result of which the PBPR relay is connected to the linear circuit again. After the relay of the arrival of the PRP releases its measles, the power circuit of the NMT transmitter is formed through its rear contact, current pulses begin to flow into the IGP rail circuit, and the NGPR decoder at the checkpoint is energized. Through the front contact of the NGPR, the alarm relay of the CSR is energized and the traffic light H is opened, and the anti-replay relay PNPR releases its measles.

The scheme at the checkpoint turns out to be in a half-senny, corresponding to the moment after the departure of the first train from station B.

When passing trains on the stage in the opposite (odd) direction, the scheme works in the same way.
