Description

Straight 20 at 0.6-0.7 kg / cm2, which corresponds to the beginning of the braking system operation. In order to ensure full service braking, the car inspector pushes button 8, the coil of the relay 15 is energized and blocked by contact 17, which turns on the electromagnet, pneumatic valve 4. At the same time, air is supplied to another chamber of the driver 2 of the crane 1 20 to 1.3-1.5 kg / cm2. To check the brake release of the train, the button 9 is pressed, the power supply of the circuit is broken and the coils of the relay 14 and 15 and the electromagnets of the pneumatic valves 3 and 4, which connect the two cavities of the drive 2 to the atmosphere, are de-energized. The actuator 2 under the action of air located in the brake line 20 transfers the driver's valve 1 to its original position and the air pressure in the brake line 20 is restored to a pressure of 5.3-5.5 kg / cm. For accelerated air charging of the brake line 20 and park lines 22 press a button 10 through which power is supplied to the electromagnet of the pneumatic valve 18, through which air is supplied from line 19 to the receiver 21, mine driver valve 1.

The effectiveness of the proposed device consists in reducing labor costs due to the possibility of testing the brakes of a train directly when inspecting wagons on parked roads. The number of operators is reduced.

Claims (1)

Claims: A device for testing brakes on trains, comprising a remote controller on which a pneumatically actuated driver valve is mounted, electro-pneumatic valves for supplying compressed air from the main line to a pneumatic drive, and an electropneumatic valve for direct communication of the main line with the brake line, means switching in electric circuits of control of windings of electropneumatic valves and control panels and park lines connected to the columns In order to reduce labor costs, it is equipped with a receiver to which the main brake and park lines and the outlet of the electropneumatic valve are connected to the main line with the brake line by means of taps, additional control panels are installed on the park paths button, and the contacts of the buttons of the same name are connected in parallel to the means of switching in the electric circuit of the winding of the corresponding electro-pneumatic valve, and and switching windings electropneumatic valves for supplying compressed air to the pneumatic actuator are designed as relays, contacts and shunt contacts connecting the windings of said valves, and each panel is a button for de-energizing the relay winding and valves.
