Description
Technical field
The invention belongs to railway transport fields, and in particular to a kind of parking brake control system for rail vehicle rescue
System.
Background technique
City railway vehicle, EMU are respectively provided with parking brake system at present, and parking brake system is by vehicle when normal operation
It organizes electrical system control to apply or alleviate, but when vehicle group failure is unable to run, Hui Ku is generally pulled by breakdown locomotive, and it is former
The parking brake of barrier vehicle group can not be controlled by breakdown locomotive, and failure EMU can not also carry out parking brake when without electricity rescue
Control will be unable to guarantee train braking safety in long term stop；In addition if parking brake control is there are failure when rescue, by
One fixed hand relieving stop brake cylinder will take a long time, and will be so that vehicle group loses parking brake ability.
Summary of the invention
The technical problem to be solved by the present invention is to design a kind of parking brake control system for rail vehicle rescue,
When so that rail vehicle failure being rescued, parking brake system can be controlled by breakdown locomotive, and not need any power supply.
In order to solve the above technical problems, the present invention provides a kind of rail vehicle rescue parking brake control system, including
Throttle valve, two-way valve, cutout cock, pressure switch, it is characterised in that: connected between the train pipe and blast main of rail vehicle
One solenoid valve, solenoid valve obtain electric, and blast main is connected with electromagnetic valve outlet, and solenoid valve power loss, train pipe is connected with electromagnetic valve outlet,
Electromagnetic valve outlet is sequentially connected throttle valve, two-way valve, cutout cock, pressure switch, and leads to Parking Brake Cylinders, wherein two-way valve
The other end connects brake-cylinder pressure pipeline, and preventing air damping and parking brake power to be superimposed causes to overload.Make electromagnetism when rescue
Valve power loss, allows the work of train pipe directly pneumatic control Parking Brake Cylinders, does not need any power supply.
The full train of train pipe penetrating orbit vehicle, and the solenoid valve company for parking control system is arranged in each with rail vehicle
It connects.
A kind of rail vehicle rescue control method of parking brake control system, it is characterised in that；
When disabled vehicle group is rescued by breakdown locomotive, the train pipe of breakdown locomotive is connect with the train pipe of disabled vehicle group, cuts off failure
The power supply of vehicle group solenoid valve, so that the compressed air of train pipe enters Parking Brake Cylinders by solenoid valve；
When breakdown locomotive, which is alleviated, to be braked, train pipe is full of pressure, and compressed air enters Parking Brake Cylinders, so that Parking Brake Cylinders
In relieved state；
When applying service braking or emergency braking when breakdown locomotive is in operation or parking, train tube pressure is reduced to common system
Dynamic decompression amount range or to be discharged be 0, Parking Brake Cylinders are also disposed to pressure identical as train pipe due to being connected to train pipe
Power realizes that parking brake is partially applied or applied completely thus；
When vehicle group, which is in, to be operated normally, the compressed air of train pipe is drained, and vehicle group obtains solenoid valve electric to pass through blast main
Stress reduction parking brake；
Apply parking brake, solenoid valve power loss when vehicle group, which is in, to be operated normally, the compressed air of Parking Brake Cylinders passes through emptying
Train pipe be also drained, parking brake apply.
The good effect that the present invention generates using the above scheme is as follows:
(1) when may be implemented in breakdown locomotive rescue failure train through the invention, breakdown locomotive directly passes through train pipe to failure
The parking brake system of vehicle group is controlled, and is not needed to carry out any operation to parking brake, is not also needed any power supply, even if
Control of the breakdown locomotive to disabled vehicle group parking brake can also be realized in disabled vehicle group parking brake control system fault condition, grasped
Make simple and rescue time can be greatlyd save, reduces the influence to normal operation order.
(2) in rescue operations, when breakdown locomotive applies service braking or emergency braking, disabled vehicle group, which can also apply, is parked
Braking, it may not be necessary to which the work of disabled vehicle group braking control system can provide braking force of train to relief car group, can suitably mention
High train rescuing speed ensures train braking safety.
Detailed description of the invention
Fig. 1 is the structure principle chart of the specific embodiment of the invention.
Specific embodiment
Referring to Fig.1, the specific embodiment of the invention include solenoid valve 01, throttle valve 02, two-way valve 03, cutout cock 04,
Pressure switch 05；Wherein the both ends of solenoid valve 01 are separately connected blast main and train pipe, realize accidental conditions and rescue work
To the control of disabled vehicle group parking brake system under condition, the outlet of solenoid valve 01 connection throttle valve, the effect of throttle valve 02 is limitation
Parking Brake Cylinders fill wind velocity.Throttle valve 02 connects one end of two-way valve 03, and the other end of two-way valve connects checking cylinder pipeline,
The compressed air of the larger one end of two-way valve pressure at two ends flows to two-way valve outlet, can prevent the folded of air damping and parking brake
It is affixed by.Cutout cock 04 is used to be truncated and empty the air feed of Parking Brake Cylinders, for cutting off parking brake when debugging or failure
Cylinder, cutout cock 04 can be monitored simultaneous with electric contact, the state of opening or closing by vehicle set control system.Pressure is opened
05 is closed for detecting the pressure of Parking Brake Cylinders pipeline, and state is fed back into vehicle set control system and is diagnosed and is controlled.
When disabled vehicle group is rescued by breakdown locomotive, the train pipe of breakdown locomotive is connect with the train pipe of disabled vehicle group, excision
The power supply of disabled vehicle group, so that solenoid valve 01 is in power failure state, train pipe exports in the conductive state with solenoid valve 01.Work as rescue
When locomotive alleviates braking, train pipe is full of pressure, and compressed air enters Parking Brake Cylinders, so that Parking Brake Cylinders, which are in, alleviates shape
State.
When applying service braking or emergency braking when breakdown locomotive is in operation or parking, train tube pressure is reduced to often
With the decompression amount range of braking or to be discharged be 0, and Parking Brake Cylinders are also disposed to and train pipe phase due to being connected to train pipe
Same pressure realizes that parking brake is partially applied or applied completely thus.
When vehicle group, which is in, to be operated normally, the compressed air of train pipe is drained, when disabled vehicle group alleviates parking brake, electricity
Magnet valve 01 is in obtain electricity condition by electrical control, and blast main and the outlet of solenoid valve 01 are connected at this time, and blast main compressed air enters
Parking Brake Cylinders make Parking Brake Cylinders be in relieved state.When disabled vehicle group applies parking brake, solenoid valve 01 is electrical
Control is in power failure state, and the compressed air of train pipe is connected with Parking Brake Cylinders at this time, since train pipe is in emptying state,
Therefore the compressed air of Parking Brake Cylinders is also drained by train pipe, and Parking Brake Cylinders are in applies state completely.
