The invention relates to the technical field of railway vehicle parking braking, and in particular relates to a railway vehicle parking brake device capable of automatically stopping and manually stopping. The device comprises a wind pressure mechanism, a hydraulic mechanism, a control mechanism and an actuating mechanism. The wind pressure mechanism comprises a parking brake cylinder, a parking air cylinder, a local pressure reducing valve and a shutoff valve, and an air path from the parking air cylinder to the local pressure reducing valve and the parking brake cylinder is connected or disconnected through the shutoff valve; reciprocating motion of a piston in the parking brake cylinder is controlled through reciprocating motion of a piston in the local pressure reducing valve, all parts of an original basic brake device of a vehicle are driven to act through the actuating mechanism, and automatic parking brake and automatic parking release of the vehicle are achieved; during manualaction, the control mechanism is manually operated, so that the hydraulic mechanism controls the reciprocating motion of the piston in the parking brake cylinder to drive the actuating mechanism to work and further drive all parts of the original basic brake device of the vehicle to work, and manual parking brake and manual parking release of the vehicle are realized.

    本发明涉及铁路车辆停放制动技术领域,具体涉及一种既可自动止动又可人工止动的铁路车辆停放制动装置,其包括风压机构、液压机构、操纵机构和执行机构。风压机构包括停放制动缸、停放风缸、局部减压阀和遮断阀,通过遮断阀联通或关断停放风缸至局部减压阀及停放制动缸的风路;通过局部减压阀内的活塞往复移动,进而控制停放制动缸内活塞的往复运动,并通过执行机构带动车辆原有基础制动装置各部件动作,实现车辆的自动停放制动及自动停放缓解;人工作用时,人工对操纵机构进行动作,使得液压机构控制停放制动缸内活塞的往复运动,带动执行机构工作,进而带动车辆原有基础制动装置各部件工作,实现车辆的人工停放制动及人工停放缓解。
