Description

one

The invention relates to railway automation, in particular to devices for automatic locking.

A device for relay semi-automatic blocking is known, which contains a plug-in and control relay of a train arriving at a station, the common power supply circuit of which includes a signal relay relay and the front contact of a reverse repeater of the approaching relay track, and the rear control switch the contact of the pointer track relay, and in the power supply circuit of the auxiliary relay - the rear contact of the track relay of the post-signal section 1.

A disadvantage of the known device is that it allows for the occurrence of a false signal of a train arriving at the station and sending the train to a busy station during a short turn off of the power of rail circuits or artificial shunting of rail circuits.

The purpose of the invention is to increase reliability in operation.

This is achieved by the fact that the train arrives at the station sequentially with the rear relay switch of the track relay relay with the front track relay link and the reverse contact relay connection of the track relay of the section of the track section &

The drawing shows a diagram of a diagram of the 1 st clause device.

The device contains a relay 1 on the train of the train on the station with pin 11, auxiliary relay 2 on contact mm 21, in L1 and whose power supply includes contacts 3 of the common alarm relay and contact 4 on the signal relay of the moon-white light of the traffic light S, reverse repeater The 6-way relay of the approximation section with the front contact 6L by the rear 6.2, is switched on via the rear contact 7 of the track relay of the section.

20 approximations 8, rear contact 9 and front contact 10 of the track relay of the post-signal section I, rear contact 12 of the switch track relay of section 13. When receiving a train at an open traffic light 5, the device works as follows. The train enters the approach area 8 by detecting the reverse repeater b. As the train advances within the station, the auxiliary relay is energized and self-blocked. 2. After the sections 8 and 11 are cleared by train, relay 2 is energized and relay 1 is self-blocked due to the slowing down of the train. In the case of artificial shunting of track circuits, auxiliary relay 2 is energized and switched off again after removing the shunt to break the circuit of relay 1 and thereby protect the device from false triggering. When the power supply feeder is turned off and on, when measles of track relays of sections 8, 11 and 13 fall out and are attracted to the flash relay cortex 6, the relay circuit 1 is absent and cannot be energized, thus eliminating the false arrival signal. . Formula of the Invention A semi-automatic relay blocking device containing an auxiliary relay 1-00 74 and a train arrival control relay, the common power supply circuit of which includes a signal relay contact and the front contact of a reverse repeater of the approaching section relay, and a power train arrive at the station the rear contact of the turnout switch relay is turned on, and the auxiliary relay of the post relay signal contact is connected to the power supply circuit of the auxiliary relay, characterized in that Improving operational reliability, the supply control relay of the train arrives at the station in series with the rear contact of the njrreBoro switch; the front contact of the track relay of the post-signal section and the rear contact of the reverse relay of the approach relay section are included.
