Description
Technical field
The outer hung type electropneumatic brake equipment of volume reservoir, is related to vehicle release of brake technical field.
Background technology
China railways network spreads all over the country, and railway transport of passengers is main stream traffic instrument.
41 divide during 28 days 4 April in 2008 in China railways operation, the T195 passenger train in Qingdao is left in descending Beijing
Operation is derailed to Jiao Jixianwang villages between Zhou village, is rushed on the outside of uplink roadbed.Just when now, Yantai to the Xuzhou of normal operation
The brake of 5034 passenger trains it is too late, finally hit with 70 kilometers of speed per hour and the vehicle that derails, locomotive and the
The compartment derailing of 1-5 sections.Jiaozhou-Jinan railway train colliding accident has resulted in 72 people death, the injured serious consequence of 416 people.
Therefore, the train braking response time is short, and the brake system response time of rail vehicle is the guarantee of safe driving.But
The rail vehicle of prior art, the time due to filling wind after braking again is generally 3-5 minutes, if ton train uses
Brake hard, then air-filled time even can be more than 10 minutes.
Train brake is exactly the motion for artificially preventing train, including it is slowed down, and does not accelerate or out of service, that is, is commonly called as
" brake ".The train or locomotive braked are released or weaken its braking action, then is referred to as " alleviating ", that is, " the pine being commonly called as
Lock ".To implement braking and alleviating the equipment set installed ON TRAINS, collectively referred to as train " brake ".
Checking cylinder fills wind (supercharging) when the characteristics of self-action air damper is brake pipe's air draft (decompression), occurs slow
Solution.Acted when distributing valve/control valve experiences the pressure decline of brake pipe during brake pipe's air draft, by auxiliary reservoir and checking cylinder
Connect, the compressed air in auxiliary reservoir is filled with checking cylinder, so as to promote brake rigging to produce brake force.Wind process is filled to be divided into
In two stages, distributing valve/control valve is experienced when the pressure of brake pipe rises and acted in the first stage, and checking cylinder is communicated to
Air produces remission effect so as to the wind in emptying checking cylinder；Second stage, on the one hand will system when distributing valve/control valve events
Dynamic cylinder is communicated to air, and brake pipe on the other hand is communicated into auxiliary reservoir and pressure reservoir, utilizes the compression in brake pipe
Air fills wind to the two reservoirs.Advantage is, when separation accident, when air-brake coupling hose is pulled off, brake pipe's blast occur for train
Drastically decline, distributing valve/control valve piston is automatic and moves rapidly into retarder location, therefore train can be braked rapidly until stopping automatically
Car.The security of train operation can be improved, when train accidental separation, can automatic stopping, avoid causing it is more serious after
Fruit.Therefore, it is widely used in the railway system of the most of country in China and the world.
But the deficiency of this brake of prior art is：Brake pipe's fills wind or air draft during train normal operation
By locomotive control, when brake pipe fills wind, compressed air can flow to the car via distributing valve/control valve of each vehicle
Pressure reservoir and auxiliary reservoir.Because the brake pipe for penetrating full train has certain length, therefore said process can be first
Occur then sequentially to occur on vehicle behind from locomotive rear portion first car is upper, until last vehicle of train, and due to each
The pressure reservoir and auxiliary reservoir of vehicle are respectively provided with certain volume, full train it is larger with air quantity.It is simultaneously all on vehicle
Wind regime is both from locomotive.Therefore, when the brake is applied to organize into groups longer train, from self-retention is responsible for when starting to fill wind
To each car pressure reservoir and auxiliary reservoir full of when stop, it may be desirable to filled again after longer time, generally braking wind when
Between generally 3-5 minutes, if having used brake hard for organizing into groups longer ton train, air-filled time is even again
Can be more than 10 minutes.Within the period, if the emergency of occurrence injury traffic safety is, it is necessary to when braking again, the system
Motivation will be unable to normally play braking effect, even wholly without brake force.
Locomotive is the locomotive engine being commonly called as.
Vehicle is the compartment being commonly called as.
The effect of brake rigging is by power transmission caused by checking cylinder and is assigned on each wheel.
Pressure reservoir is for distributing valve or controls valve events to provide the wind regime of power, and distributing valve or control valve act all every time
The compressed air in pressure reservoir can be consumed.
Electro-pneumatic brake is the abbreviation of electronically controlled pneumatic brake machine, is to install the electricity such as magnetic valve additional on the basis of air damper
Gas control unit and formed.Its feature is：When driver implements braking maneuver, penetrate the pilot arranged entirely and send telecommunications
Number, the electric empty distributing valve energized action of each vehicle in train, brake pipe is connected air, because brake pipe is depressurized, the system
Motivation can make auxiliary reservoir fill wind generation braking action to checking cylinder as self-action air damper, but due to each vehicle
Energized action arranges the wind in brake pipe to air to the empty distributing valve of electricity simultaneously, compared with the automatic brake valve only by being located on locomotive
At one during air draft, air draft speed is very fast and the uniformity of the front and rear generation braking action of train is good.Because auxiliary reservoir fills to checking cylinder
Gas is a process gradually occurred, and the process can stop or continue at any time, thus brake force can directly reach it is required
Value is stepped up several times, and directly braking is referred to as when brake force directly reaches required value, when brake force progressively increases by several times
Added-time is referred to as graduated application.When driver implements alleviation action, penetrate the pilot that arranges entirely and send electric signal, each car in train
Electric empty distributing valve energized action, connect alleviate reservoir to brake pipe path, it is rapid from alleviation reservoir to brake pipe
Wind is filled, the brake pipe for making to arrange entirely almost starts simultaneously at supercharging, and because brake pipe is pressurized, the brake can be empty as self-action
Gas brake equally makes checking cylinder connect air, checking cylinder air draft, and the uniformity that train is front and rear to occur mitigation is good.But due to
The magnetic valve that several pilots arranged entirely by penetrating are controlled is added inside the empty distributing valve of electricity, these magnetic valves are when without electricity
In opening state, the empty distributing valve of electricity can take action certainly as self-action air damper according to brake pipe's pressure change
Make.Wherein braking earthen pipe magnetic valve can cut off the gas circuit that braking earthen pipe leads to air, during checking cylinder air draft, work as system
When dynamic cylinder pressure drops to required value, driver can control the electromagnetism valve events by penetrating the pilot arranged entirely, stop
The air draft process of checking cylinder.The opening state of the magnetic valve can be recovered when needing and continuing and reduce brake force continues checking cylinder
Air draft, with implementation phase mitigation." automatically controlled " is used in the manipulation control of braking action, but braking action motive power still compresses sky
Gas.Compared with self-action air damper, the uniformity of rapid, the full train action of electro-pneumatic brake response is good and adds the stage
Mitigation capability.Meanwhile in the automatically controlled failure for some reason of brake, its still practicable " gas control " (atmospheric pressure control) is interim to become
Into self-action air damper.It is very high or marshalling is very long in train speed, when air damper is difficult to satisfaction and required, using electric empty
Brake can substantially improve the uniformity of the braking of train front and rear part and mitigation, significantly mitigate Lognitudinal Impact of Trains, and contract
Short braking distance, in the world many bullet trains all employ electro-pneumatic brake.But due to each when electro-pneumatic brake fills wind
Vehicle is only controlled by electric signal, and it fills during wind the main wind regime needed still will be provided by locomotive, alleviate the work of reservoir
With being intended merely to coordinating the uniformity that ensures that full row are alleviated during electric pneumatic breaking, even if alleviation reservoir is the increase in, in electric signal
Control under the auxiliary reservoir of each vehicle and pressure reservoir can be made almost to start simultaneously at and fill wind, but it is smaller to alleviate reservoir capacity
And maximum pressure is not more than the level pressure of brake pipe, brake pipe certainly will be only a small amount of wind, most wind are provided
Still need to be provided by locomotive, its air-filled time still can not effectively be shortened.
As can be seen here, either self-action air damper or electro-pneumatic brake were after once alleviate, in short-term
In fail to return to standard value, it is necessary to which without normal direction checking cylinder to provide enough compression when braking empty due to the pressure in auxiliary reservoir
Gas, so that brake can not produce enough brake force, even wholly without braking effect.
The content of the invention
On the 4.28 accident same day, the uplink and downlink speed limit in incident location is 80km/h, and descending T195 times train is because of operation
Improper to rush speed limit derailing by mistake, the vehicle accumbency of derailing now has no larger injures and deaths on adjacent uplink.It is but at this moment up
Speed limit section of No. 5034 trains in direction due to just entering 80km/h, this train is by its standard speed of service 120km/h
As defined in speed governing to speed limit section during 80km/h, used and once braked, so that when driver has found accumbency on uplink
During the derailing vehicle of T195 times, although taking brake hard measure in time, once braked due to just using, each car
Auxiliary reservoir compressed air not yet reach normal pressure can not be provided for checking cylinder abundance compressed air cause brake nothing
Power, cause 5034 Train Stoppings not as good as the derailing vehicle for knocking T195 times.It is dead that 72 people are just result in just because of this Secondary Shocks
