In order to solve the above technical problems, the utility model provides a kind of rail vehicle rescue braking system, including railcar
The existing aerobraking control unit of braking system, aerobraking control unit include two-way valve, emergency braking solenoid valve, claim
Weight pressure limiting valve, relay valve, pressure regulator, relaying valve outlet and checking cylinder piping connection, it is characterised in that: further include pneumatically rescuing
Control unit is helped, pneumatic control unit of rescuing includes pressure reducing valve, solenoid valve, test interface, two piston valves, wherein rail vehicle
The pneumatic rescue control unit of braking cylinder connection decompression valve inlet, decompression valve outlet is consecutively connected to solenoid valve and second living
Plug valve, and increased two-way valve is connect between the emergency braking solenoid valve in aerobraking control unit and weighing pressure limiting valve,
One end connection braking cylinder of first piston valve, the other end connect emergency braking solenoid valve and pressure in aerobraking control unit
Draught control mechanism；First piston valve and second piston valve are connect with train pipe, are controlled by train tube pressure.Train pipe penetrating orbit
The full train of vehicle, and connect with the increased pneumatic rescue control unit of rail vehicle each car,
Solenoid valve in the pneumatic rescue control unit is connect with train emergency braking electrical safety loop, in train
It can provide the brake pressure of redundancy when applying the emergency brake when normal operation, further ensure train braking safety.
A kind of control method of rail vehicle rescue braking system, it is characterised in that:
When disabled vehicle group is rescued by locomotive, the emergency braking electrical safety loop service of disabled vehicle group is disconnected, by railcar
Train pipe be connected with the train pipe of breakdown locomotive；
When breakdown locomotive alleviates braking, train pipe is full of pressure, and rail vehicle passes through pneumatically rescue control unit control row
The control gas circuit being connected with aerobraking control unit is put, so that failure train braking system is in relieved state；
When breakdown locomotive applies service braking, train pipe is disposed to the decompression amount range of service braking, rail vehicle
Enter aerobraking control unit by pneumatically rescuing control unit control setting pressure, so that failure train applies the system of setting
Dynamic pressure；
When breakdown locomotive applies the emergency brake, train pipe is drained, and rail vehicle is by pneumatically rescuing control unit control
The pressure of system braking cylinder is directly entered aerobraking control unit, the pressure so that failure train applies the emergency brake.
The good effect that the utility model generates using the above scheme is as follows:
(1) it by pneumatically rescuing control unit and train pipe, can be realized in rescue, breakdown locomotive is to failure train
Braking system is controlled, and breakdown locomotive and failure train all have stopping power at this time, can significantly improve rescue operations
Train speed saves rescue time, reduces the influence to normal operation order.
(2) when breakdown locomotive rescue failure train, the braking system for not needing failure train is in power supply state, only passes through
The braking function of failure train can be realized in the pneumatic control of breakdown locomotive, realizes and rescues without electricity, both ensure that train safety,
It can avoid in failure Electric failure since accumulator capacity limitation not can guarantee the rescue of relatively long distance.
(3) pneumatically rescue control unit has two ranks of service braking and emergency braking, can according to circumstances apply corresponding
Braking rank, ensure that train safety.
(4) pneumatically rescue control unit is in automatic off position when train operates normally, and does not influence aerobraking
The normal work of control unit.
Detailed description of the invention
Fig. 1 is the structure principle chart of specific embodiment of the present invention.
Specific embodiment
Referring to Fig.1, specific embodiment of the present invention includes pneumatic rescue control unit and rail vehicle braking system
Existing aerobraking control unit, pneumatic control unit of rescuing includes that piston valve 01, piston valve 02, solenoid valve 03, test connect
Mouth 04, pressure reducing valve 05；The wherein braking cylinder connection of piston valve 01, the entrance of pressure reducing valve 05 and rail vehicle braking system, it is living
The outlet of plug valve 01 in aerobraking control unit emergency braking solenoid valve 07 and pressure regulator 10 connect；Piston valve 02
Outlet connect with two-way valve 06 by B mouthfuls of aerobraking control unit；The control interface of piston valve 01 and piston valve 02 passes through L
Mouth is connect with train pipe 11, and 01 setting value of piston valve meets train pipe brake pipe pressure amount movement conducting gas circuit, piston valve 02
Setting value meets train pipe service braking decompression amount range movement conducting gas circuit；The emergency braking of the connection rail vehicle of solenoid valve 03
Electrical safety loop, power failure state gas circuit are in the conductive state.Aerobraking control unit includes two-way valve 06, emergency braking electricity
Magnet valve 07, weighing pressure limiting valve 08, relay valve 09, pressure regulator 10, relaying valve outlet C and checking cylinder piping connection, weighing limit
08 entrance T of pressure valve and air spring piping connection.
When failure train is rescued by breakdown locomotive, failure train is in by rescue mode, the train pipe of breakdown locomotive and event
The train pipe 11 for hindering train connects, and disconnects the emergency braking electrical safety loop of failure train, so that connect with security loop
Solenoid valve 03 and emergency braking solenoid valve 07 are in power failure state, and gas circuit is in the conductive state.Alleviate when breakdown locomotive and brakes
When, train pipe is full of pressure, and piston valve 01 and piston valve 02 are in truncation air draft state, are connected with aerobraking control unit
Gas circuit is discharged, so that failure train braking system is in relieved state.
When breakdown locomotive applies service braking, train pipe is disposed to the decompression amount range of service braking, and piston 02 is dynamic
Make that gas circuit is in the conductive state, compressed air enters the double of aerobraking control unit after the decompression of pressure reducing valve 05 is setting value
To 06 left side of valve, so that failure train applies fixed brake pressure；Piston valve 01 is still in truncation air draft state, emergency braking
It is isolated.
When breakdown locomotive applies the emergency brake, train pipe is drained, and piston valve 01 and piston valve 02 are acted to be in and be led
Logical state, compressed air enter simultaneously from the B mouth of aerobraking control unit and A mouthfuls, and 06 pressure at both sides of two-way valve is biggish tight
Anxious brake pressure makes failure train apply the emergency brake by weighing pressure limiting valve 08.
When vehicle group, which is in, to be operated normally, the compressed air of train pipe is drained, and piston valve 01 and 02 is acted to be in and be led
Logical state, but under non-emergent damped condition, since emergency braking electrical safety circuit is in closed state, solenoid valve 03 is obtained
Electricity is in truncation air draft state, so that the B mouth of aerobraking control unit is in discharge state, therefore in the traction of normal operation
Under service braking operating condition, aerobraking control unit is not influenced by pneumatic rescue control unit.Under emergency braking operating condition,
Aerobraking control unit emergency braking 07 power loss of solenoid valve is in the conductive state, and failure train is caused to apply the emergency brake, and
Solenoid valve 03 is also at power loss on state and is filled with fixation pressure on the left of two-way valve, and the braking of redundancy is kept to apply, can be more
Benefit failure train emergency braking solenoid valve failure can not apply the emergency brake the case where causing brake force to be lost, and guarantee train peace
Entirely.
