The invention relates to the technical field of railway vehicles, in particular to an anti-sliding device for wind power automatic butt joint and separation of a railway vehicle, which comprises a front chamber, a middle chamber and a rear chamber which are arranged in a ventilation pipeline, a piston cylinder is arranged in the rear chamber, and a piston rod end of the piston cylinder is providedwith a piston rod capable of extending out along with the piston rod to close the ventilation pipeline, an opening-closing device which contracts to open the ventilation pipeline, the piston cylinderfront cavity is provided with a fifth vent hole communicated with the rear cavity, the piston cylinder rear cavity is provided with a sixth vent hole, the sixth vent hole is communicated with the front cavity through an outer air pipe, and when two vehicles are separated, due to the fact that the hole diameter of the fifth vent hole is far smaller than that of the sixth vent hole, the two vehicles are separated, therefore, the exhaust speed of the pressure air in the front cavity is lower than that of the pressure air in the rear cavity, the air pressure in the front cavity of the piston cylinder is higher than that of the rear cavity of the piston cylinder, the piston rod is prevented from extending out to close the ventilation pipeline, enough time is reserved for exhaust of the pressure air in the train pipe to enable a separated train to brake in situ, and train sliding is avoided.

    本发明涉及铁路车辆技术领域,尤其涉及一种用于铁路车辆风电自动对接及分离的防溜车装置,包括通风管道内设置的前部、中部、后部三个腔室,后部腔室安装有活塞缸,活塞缸的活塞杆端安装有能够随活塞杆伸出关闭通风管道,收缩打开通风管道的启闭装置,活塞缸前腔室设置有与后部腔室相通的第五通气孔,活塞缸后腔室设置有第六通气孔,第六通气孔通过外风管与前部腔室相通,两车辆分离时因第五通气孔的孔径远小于第六通气孔,故前腔室压力空气的排放速度小于后腔室压力空气的排放速度,使活塞缸前腔室中的空气压力大于活塞缸后腔室的空气压力,阻碍活塞杆伸出关闭通风管道,为列车管中压力空气的排放预留足够时间使分离车辆原地制动,避免车辆溜车。
