Description

The invention relates to a ycTjJoflcTBaM for automatic electrical signaling at the intersections of tram lines by simultaneously switching on two groups of signal lamps, permissive and prohibitive, along cross lines of railway tracks. This is done by means of auxiliary contact air wires located in front of the crossroads and connected through the current collector on the tram car to the working wire.

The proposed device is intended to provide signals in the event of a simultaneous approach to the overlap. a line of tram wagons in two directions

In FIG. 1 shows a circuit for switching on signaling relays; and FIG. 2-scheme of the device auxiliary wires at intersections. ,

The proposed automatic device consists of a series of electromagnetic relays A, B, D j G, K J1, in which the relays A and B are used to adventure or disconnect the device from the working wire Zi, and the other relays to switch on segments of auxiliary air wires located in front of a crossroads. In addition, at the stops before the intersection on each line of the air wires to the working wires are added by separate sections of auxiliary wires and one by one; section, located after the tram stop cars. These pieces. they are intended to be switched on while simultaneously approaching the intersection of two tram trains in two transverse directions with the expectation of releasing the auxiliary wire for another car that follows, which also drives the signal device.

The operation of the proposed signal device is as follows. For example, when crossing cars on line a and & the cable is simultaneously closed by the extension wire for the entire time of the carriage stand or for the time of the last passage of the extension wire. The current from the working wire, getting into the extension wire, will turn on the device. Relay, 4, being energized, closes contact V., Turning off relay I takes place at point O. The current circuit will be closed through contact / K, contact O and relay B. Relay 5 closes contact FH simultaneously with it opens contact Oj. When contact V is closed, relay Xj is released, since the current circuit is established via contact II, and relay A is open at this moment. When then contact V is turned on, in the signal lamp, which is always one-sided, the signal lamps for the a-b ol: line of color and for the c-d-other line turn on through the conductor b. When the car passes the intersection, the main circuit with the auxiliary wire section will be closed again, and the current will pass through the G relay that opens the circuit in contact // and relay 5 turns off, contact V opens and contact O turns out to be closed. The signal light in this case lights up in the third color, indicating that the path is clear.

The lamps of the last color of the signal light are powered through the contacts O and Oi. ,

For paths c and d, the device acts in the same way, but only the work in this case is carried out already through relays A, F, and D. Further, when at the stops simultaneously. will go down tram cars in both ways with or d to a or &, the circuit will be closed through the relay / and D and in the / / lantern lights up

Only the third signal, “The path is free, but the automaton will be turned off. The leader of one of the cars should, in this case, advance the carriage forward, as a result of which the D and L1 chains will open and. the machine will operate in the order indicated above.

The subject matter of the invention.

A device for automatic electrical signaling at the intersections of tram lines using auxiliary wires, located in front of the intersection and connected to the working wire through a current collector on the car, to turn on warning lamps and a self-closing electromagnetic relay that keeps these lamps in the on position until The current collector is closed by auxiliary wire sections located behind the intersection, characterized in that the auxiliary sections x wires located in front of the intersection are each erected from several separate sections with the goal that, while approaching the intersection of the train line in two transverse directions, one of them could, having advanced and left the auxiliary wire, allow the other to operate alarm device.
