The invention discloses a parking brake control device capable of automatically relieving in a rescued mode, and relates to the technical field of railway vehicle brake systems. The parking brake control device capable of automatically relieving in the rescued mode comprises a two-way check valve and a first cutout cock which are arranged in sequence, and the first cutout cock is communicated with a parking brake cylinder; a piston valve is arranged on the pipeline between the two-way check valve and the first cutout cock, and a first air cylinder, a first pressure reducing valve and a first electromagnetic valve are sequentially arranged on the pipeline between the piston valve and the first cutout cock from left to right; an exhaust port of the first electromagnetic valve communicates with the outlet end of the first pressure reducing valve. The problems that the rescue efficiency is seriously affected due to the fact that getting-off operation needs to be carried out on each parking braking device for parking braking, and if getting-off operation is not allowed on an accident road section, a train can only run with a brake when being rescued, the rescue speed limit is very low at the moment, and the rescue efficiency is further affected are solved.
本发明公开了被救援模式下自动缓解的停放制动控制装置,涉及轨道车辆制动系统技术领域。其中,该被救援模式下自动缓解的停放制动控制装置,包括:顺序设置的双向止回阀和第一截断塞门,第一截断塞门与停放制动缸连通;双向止回阀与第一截断塞门之间的管路上设置有活塞阀,活塞阀与第一截断塞门之间的管路上从左至右依次设置有第一风缸、第一减压阀和第一电磁阀;第一电磁阀的排气口与第一减压阀的出口端连通。本发明,解决停放制动需要下车对每一个停放制动装置进行手动操作隔离,严重影响救援效率,如果事故路段不允许下车操作,则列车被救援时只能带闸跑,此时救援限速非常低,更加影响救援效率的问题。
