The invention provides a parking brake cylinder release device and a rail train. The parking brake cylinder release device comprises: a first connecting rod and a first traction rope. The first connecting rod is rotatably connected to a bogie, and a rotating axis of the first connecting rod is perpendicular to a center line of the first connecting rod; a driving end of the first connecting rod isconnected to the first traction rope, a movable end of the first connecting rod is connected to a piston rod of the parking brake cylinder, and the distance between the driving end of the first connecting rod and the rotating axis of the first connecting rod is larger than that between the movable end and the rotating axis of the first connecting rod; a power arm of the first connecting rod is larger than a resistance arm of the first connecting rod. Compared with the prior art that a worker directly pulls the piston rod of a parking brake cylinder, a piston rod with large resistance can be driven to stretch out of the cylinder body through a small pulling force for pulling the first traction rope, and operation is labor-saving.

    本发明提供一种停放制动缸缓解装置及轨道列车,该停放制动缸缓解装置包括:第一连杆以及第一牵引绳;第一连杆可转动的与转向架连接,且第一连杆的转动轴线与第一连杆的中心线垂直;第一连杆的驱动端与第一牵引绳连接,第一连杆的活动端与停放制动缸的活塞杆连接,且第一连杆的驱动端与第一连杆的转动轴线的距离大于第一连杆的活动端与第一连杆的转动轴线的距离;第一连杆的动力臂大于第一连杆的阻力臂,与现有技术中工作人员直接拉拔停放制动缸的活塞杆相比,较小的拉拔第一牵引绳的拉力即可驱动具有较大阻力的活塞杆由缸体内伸出,操作省力。
