Description
Technical field
The present invention is a kind of railway locomotive block construction that relates to, and refers in particular to the automatic air brake control method and the system and device of the urgent or power failure state of a kind of railway locomotive, is mainly used in perfect in shape and function and lifting in the railway locomotive air brake control system.
Background technology
In the existing Locomotive Brake System, homemade design-calculated DK-1 brake has passed through the utilization of decades, and the key property of its distributing valve control system is checked fully.But along with the progress of control science and technology and improving constantly of railway transportation requirement, there are a little spaces of improving and promoting in the distributing valve control system, and wherein the control of braking link has just a little not enough under urgent or power failure state.
One, in original DK-1 brake distributing valve control system; When urgent or power failure state; Detected by distributing valve pumping chamber portion and introduce total wind after the consequent pressure change such as train pipe and carry out emergency braking to the distributing valve chamber volume and control, this mode weak point has:
1, the maximum brake pressure of locomotive can cause the continuous fluctuation of locomotive brake cylinder brake-pressure by the control of the safety valve air draft on the distributing valve.
2, the continuous air draft of the safety valve on the distributing valve causes the damage of safety valve easily, and the fault rate of safety valve is very high in practice.
3, behind the emergency braking, little lock to the control ability of locomotive brake cylinder pressure very a little less than, random controlling machine brake cylinder pressure.
4, after the locomotive outage, total wind can not only be wasted wind regime but also influence the safety valve life-span through the continuous air draft of safety valve on the distributing valve.
Two, improve in the design at relevant utility model patent; During the control of locomotive emergency braking is to fill wind by relevant electropneumatic valve to the distributing valve chamber volume to realize the control to locomotive brake cylinder brake-pressure; Just as locomotive service braking control system part; The shortcoming by distributing valve pumping chamber portion control has been avoided in such design, but also some weak point:
1, goes to realize that with locomotive service braking control system locomotive emergency braking controllable function is not too suitable,, be difficult to accomplish to take into account because time requirement is different.
2, the autobrake that can not accomplish locomotive after system's dead electricity.
Therefore, necessary air brake control method and system and device urgent to existing railway locomotive or power failure state improve.
Summary of the invention
The objective of the invention is for solving the distributing valve control system part existing deficiency in the air brake control of urgent or power failure state in the DK-1 brake system; A kind of distributing valve control system that can let is proposed under the emergency state; Control brake cylinder pressure rises and stablizes rapidly; The ability of little lock controlling machine brake cylinder pressure strengthens, and reduces the fault rate of distributing valve system, and under the system cut-off state, lets locomotive autobrake and do not arrange the air brake control method and the system and device of total wind.
