Description

 The invention relates to devices for signaling, centralization and blocking in railway transport, and in particular to devices for interval regulation of the movement of trains on stages.

 A device is known for automatic locking, containing track generators and receivers of rail chains and isolating joints installed at traffic lights, separating rail chains of block sections (Dmitriev V.S., Minin V.A. Self-locking systems with rail circuits of tone frequency, M .: Transport, 1992, p. 88-95). A disadvantage of the known device is the need to use the most unreliable device of the rail chains - insulating joints, significantly reducing the reliability of the auto-lock.

 Closest to the present invention is an automatic locking device with rail chains without insulating joints (ed. St. N 1418152, class B 61 L 23/16, (prior. 10.27.86), containing track links connected to the rail threads sequentially along the path generators and receivers of rail circuits of track sections with output relays and an automatic locomotive signal control unit, whose input is connected to the power source via series-connected contacts of the track relays. additional to the rail threads, one for each section of the track, defining the boundaries of the sections of the track by a generator and a receiver with a track relay at the output and a traffic light installed at the border of a track section, the fire control unit of which is connected to the mentioned power source through series-connected contacts of the track relays of the receivers sections of the track and boundaries of the sections of the track, and the contact of the track relay of the receiver is connected in series with the contacts of the track relays to the input of the automatic locomotive signaling unit site boundaries. This device is taken as a prototype.

 The disadvantage of the prototype is the need to organize within the track (block section) two additional rail chains of the borders of block sections (track sections) and the shift of the connection point of the generator of rail chains of the border of the block section relative to the installation location of the traffic light by a distance equal to the area of the additional rail shunt chains forward along the train.

 This disadvantage especially affects suburban sections with heavy train traffic, where the length of the block section is not more than 800 m.

 And on multi-track lines, where two-way trains are provided for each way along the automatic blocking traffic lights that are located on traffic light bridges, the movement of traffic lights is difficult, and in most cases it is impossible to shift the traffic light relative to the connection point of the rail circuit generator of the block section border.

 The task to which the claimed invention is directed is to increase the safety of train traffic.

 The technical result that can be obtained by using the invention is to simplify the device and increase the reliability of automatic blocking with two-way train movement according to the indications of traffic lights.

 The problem is solved due to the fact that in the device of automatic blocking with rail circuits without insulating joints, containing a track generator and track receivers of rail chains located between the traffic lights, within each block section two rail chains are organized, powered by a common generator, connected to the rail threads in the middle of the block section, and between the track receivers and the rail threads included front contacts of the directional repeater repeaters connecting the track receiver rail to the filaments at a distance zone of additional shunting the track circuit from the traffic flow during the movement of the train depending on the established direction.

 Thus, improving the safety of train traffic in this technical solution is achieved by changing the device layout by eliminating the need for two additional rail chains of the block section boundaries and reducing the number of electronic equipment.

 The invention is illustrated by the drawing, which shows a diagram of the rail chains within the block area.

 The inventive device contains: 1 - 4 - way (passing) traffic lights, the distance between which is a block section; 5 - rail chain generator; 6 - rail threads; 7 - 10 - track receivers rail chains with track relays; 11 - relay relay follower relay contacts for one set movement; 12 - relay relay follower relay contacts for another set direction of travel.

 In this case, the track receivers of the rail chains 7 to 10 are placed between the traffic lights 1 to 4. Within the block section, two rail chains are arranged that are connected to the rail chain generator 5 connected to the rail threads 6 in the middle of the block section. Between the track receivers 7-10 and the rail threads 6, front contacts 11 and 12 of the repeater relay of the direction relay (not shown) are connected for one or the other set direction of travel.

 Normally, as can be seen from the drawing, the direction of movement along the traffic lights 1 and 2 is established, the generator 5 is connected to the rails in the middle of the block section and rail circuits 6 are fed from it, to which the rail circuit receivers 7 - 10 are connected by the front contacts 11 of the direction repeater repeater to the points of the rail chains located at a distance of the zone of additional shunting of the jointless rail chain behind the traffic lights 1 and 2 in the direction of the train.

 When the direction of movement changes, the front contacts of the repeater of the changeover relay 11 are open and the front contacts of the repeater of the changeover relay 12 are closed, with which the track receivers 7-10 of the rail circuits are respectively connected to the distance of the additional bypass zone behind the traffic lights 3 and 4 in the direction of the train .

 With this switching of the rail circuit receivers, in addition to the technical result noted above, when using the invention, a certain decrease in the size of the additional shunt zone is achieved, since the first rail circuit of the block section along the train always turns out to be shorter than the second.
