The invention discloses a vertical circulating stereo garage providing liftable barrier-free bidirectional vehicle going-out channels. The vertical circulating stereo garage comprises a split type hanging basket vehicle carrying board, a full-automatic vehicle blocking device, a fixing end guide rail, a movable end guide rail, a guide rail lifting system, and a telescopic level-filling platform. The full-automatic vehicle blocking device realizes functions of rising vehicle blocking and falling level filling. The movable end guide rail is arranged under the fixing end guide rail, and is connected with the guide rail lifting system. The guide rail lifting system drives the movable end guide rail to fall to make a vehicle going-out space of the split type hanging basket vehicle carrying board. The guide rail lifting system drives the movable end guide rail to rise, to form a vehicle carrying board guiding rail with the fixing end guide rail. Power of the telescopic level-filling platformis provided by the guide rail lifting system, to fill a front end vehicle going-out gap of the split type hanging basket vehicle carrying board. The stereo garage ensures that when a vehicle goes forward and runs into a garage, the vehicle is limited by the vehicle blocking device and can be accurately parked in place on the vehicle carrying board. When the vehicle drives out of the garage, the vehicle reasonably selects to go forward out of the garage, or go backward out of the garage.
