SU965853A1 - Arrangement for counting unloaded rail cars - Google Patents

Description

The invention relates to rail transport and can be used in the automation of rolling stock accounting.

A device for counting unloaded wagons is known, which contains a pulse-forming relay, the closing contact of which is included in the power supply circuit of the registering relay, and one output of the winding through the closing contact of the rotation control relay of the wagon rotor is connected to one pole of the power supply, to which the forming-conditioner pulses connected one output winding of the memory relay tl The disadvantage of the known device lies in the possibility of false alarms during technological operations, due to nnyh rotor rotation Vagonooprokidyvateli without trolley, which reduces reliability.

The aim of the invention is to increase the reliability of the results.

The goal is achieved by the fact that the device is equipped with a storage capacitor, a photosensor and switched on through the contact of the latter

relay control of the entry of the car into the rotor of the car dumper, one closing contact of which is connected to another winding terminal of the memory relay, one capacitor plate connected directly to one pole of the power source, and another through the disconnecting contact of the monitoring relay of the car entering the rotor of the rollover 10 tilter and resistor - to the other pole, and through the other closing contact of the relay controlling the approach of the car into the rotor and the diode - to another terminal of the winding of the specified relay-driver

15 and to one make contact of the relay monitoring the approach of the car into the rotor, the last contact through the closing contact of the memory relay connected to the other pole of the power source.

25 control relays for entering the car into the rotor of a car dumper having contacts 3.1, 3.2, 3.3, storage capacitor 4, diode 5, resistor 6, winding 7, memory relay having contact 7.1, winding 8 of the relay-shaped 30 pulse gel having contacts 8, one,. 8.2, with the contact 9 of the control relay of the rotor of the car dumper connected to the power supply circuit of the winding 8 (the relay winding is not shown). The device also contains a recording relay 10. The device operates as follows. In the absence of a car in the car dumper, the capacitor 4 is charged through a resistor B and pin 3.1 to the voltage of the power source 2. When the car enters the rotor of the tilting car, a photo sensor is activated, contact 1 is closed in the power supply circuit of the winding 3 of the car entrance control relay into the rotor, which connects capacitor 4 through contact 3.2 and contact 3.3 to the winding 7 of the memory relay, which operates and becomes self-blocking via its contact 7.1. When the rotor / car dumper rotates, the relay controls the gate of the rotor and closes its contact 9 in the power supply circuit of the winding 8 of the relay-former, which, when closed, closes its contact 8.2 in the power supply circuit of the registering relay 10 and opens its contact 8.1 with a time delay of power supply circuits: hank 7 memory relays. Since capacitor 4 is discharged when a memory relay is connected to winding 7, the memory relay repeatedly does not work. To activate it, it is necessary to remove the car from the rotor of the car dumper and, after releasing contact 1, the power supply circuit of the winding .3 closes, contact 3.1 is closed, forming a charge circuit of the capacitor 4. If after the arrival of the car, there is no tipping van, or If it comes back, the devices will not work falsely, and any operations with a rotor without a car will also not cause false work. Thus, the device provides a reliable / invoice for wagons unloaded on a wagon tipping machine, which gives an economic effect of the order of 10 thousand rubles. for one coking plant. The invention of the device for counting unloaded cars, containing a relay pulse shaper, the closing contact of which is included in the power supply circuit of the registering relay, and one winding terminal through the closing contact of the rotor rotation control switch of the car dumper is connected to one pole of the power source, to which the relay The pulse driver is connected to one output winding of the memory relay, which is connected to it. so that, in order to increase the reliability of the results, it is equipped with a storage capacitor, a photo sensor and the last control relay of the car entering the rotor of the car dumper connected via the contact of the last relay contact of the memory relay, one plate of the storage capacitor connected directly to one pole of the power source, another through the breaker contact of the control relay of the car entering the rotor of the car dumper and the resistor to the other pole, and through the other the closing contact of the control relay of the approach of the car to the rotor and the diode to another winding terminal of the specified relay driver. And to the single closing contact of the control relay of the approach of the car to the rotor, the latter contact is connected to the other pole of the power source through the secondary contact. .
