SU30713A1 - A device for signaling between cars of a tram train - Google Patents

Description

Signaling devices are already known for communicating between cars of a tram train using signal lamps located in front of the car driver, the extinction of which is signaled by a traffic signal, and their burning by a stop signal. Equally well known are such devices in which, to prevent the circuit from opening by releasing the conductor to a button signal, a self-locking relay is applied, the measles of which bypasses this button. In the proposed device, these already known parts of the device are used, and the invention consists in connecting a signal wire to the signal wire with an auxiliary wire consisting of a number of pieces of wire connected in series to each other at the contacts closed by the cords of the self-blocking relay.

The drawing schematically depicts a signaling device in a tram train consisting of one motor car 7 and two trailer cars 2 and 3.

The equipment of each trailer car consists of two buttons (7 and 27 in car 3 vi 8 and 28 - in car 2) and one self-blocking switch (13 in the car

(182)

5 and 14 - in the car 2), closing, drawing the core, two pairs of contacts (75 and 77 in the car 3, 18 and 19 in the car 2).

In parallel with each of the two buttons, the necessary number of buttons with the same effect and placed in different places of the carriage can be connected.

The equipment of a motor car T is exposed from the equipment of a trailer car only by the fact that its latching relay 15 has three pairs of contacts 20, 21 and 22, of which, when the relay is not energized, are contacts 27 and the contacts 20 and 22 are open 27 is opened and contacts 20 and 22 are closed. In addition, there is a warning lamp in the motor car in front of the car driver.

Normally, while in motion, the instruments are in the state indicated; in the drawing. At the stop, each conductor monitors only his BaroHOW and presses the button 27, 28 or 29, do not wait for signals from other conductors, as soon as his car is ready for departure.

Suppose that the possibility of departure is obtained from the carriages in a barely alternate sequence: first of all it receives the opportunity to file; Send the wagon conductor 2 departure., then wagon conductor / and, finally, wagon conductor 3.

The wagon conductor 2 presses the button 28; as a result, the circuit is clamped from the contact wire 25 through the contacts 5, closed with the pressed button 2, the relay coil 14, the lower connecting wire, the lamp 2b ground. Lamp 25 lights up. At the same time, the relay 14 is attracted to the relay, the circuit described is additionally connected through the contacts 75 connected in parallel with the contacts 5. Therefore, the relay 14 remains excited and keeps the measles in. The position is gripped; despite the fact that the button 28 is released, the lamp 26 does not "go out.

Then, in order of sequence, the wagon conductor 7 presses the button 29, which entails, similarly to the previous, self-blocking relay 15, which, in this case, opens the section of the upper connecting wire in the contacts 27.

The lamp 25 continues to burn, but it burns more brightly than because it is connected in series with two relays of 14 and 15 connected in parallel.

 Finally, pressing the button 27 gives the signal to the conductor of the car 3, due to what the relay 75 operates. Lamp 26: continues to burn. All the separate cutting wires from the top of the connecting wire are closed between themselves. And they form a solid wire that is open only in the contacts W as long as the driver of the car 3 keeps the button 27 on the head. As soon as the button 27 is released, the contacts fO close and the lower soy: the separator wire is connected to the contact wire through the contacts 22, 72, 79, 77, 77, 70, as a result of which the relays J3, / 4, 15 are short-circuited and therefore deprived of excitation. .: The anchors return to their original position under the action of springs. V The lamp 26 is extinguished, which is what the driver is signaling to send. The device after - THIS is ready for operation at the next stop.

Buttons 7, 8, 9 make it possible to turn on relays 13, 14, 15 directly corresponding to the corresponding conductor. If, for example, during the movement it is necessary for some reason to stop the train, the conductor, for example, car 2 presses button 28, lighting the lamp 26. The driver stops the tram. On passing, the need to stop the conductor of the indicated car presses button 8, short-circuiting the winding of the triggered relay 14, which entails switching off the lamp, indicating that the train may be moved.

The electric connection of the cars to each other is made between the automatic-type carriage connection 24, which is short-circuited by wires 23 and 30 when the connection 24 is open (in the end couplers).

The scheme of each car is symmetrical, as a result of which each car can be turned to the adjacent one by any site.

At the same time, it is only necessary to monitor the flow, so that the chains of the upper and lower connecting wires do not change places.

The subject matter of the invention.

1. A device for signaling between cars of a tram train using self-blocking relays that shunt contacts that close the signal lamp circuit, characterized in that, in order to get the signal 26, which serves as a signal, after the corresponding signals from all train cars go, the auxiliary a wire consisting of a series of pieces of wire connected in series with each other at the contacts closed by the corners of the self-blocking relays 13, 14, 75 and serving for closing TKO last.

 A device according to claim 1, applying contacts 7, 8, 9, shunting the windings of relays 75, 14, 15 and serving to send a departure signal after the train stopped by the respective carriage. to the author's certificate of A.V. No. 80713 Poros Tnikov
