A railway freight car automatic picking off and coupling up device provided by the present invention comprises a fixing device arranged on a car coupler, a wind path connecting device connected with an air duct, opening a wind path automatically when two couplers are coupled up and closing the wind path automatically when the external forces disappear; a circuit connecting device comprising an electric connection joint and a protection unit used for isolating the electric connection joint. When the two car couplers are coupled up and under the action of the external forces contacted with the fixing device, the protection unit is turned on, and the electric connection joint is connected and electrified; when the external forces disappear, the electric connection joint is cut off, and the protection unit resets and isolates the electric connection joint; the wind path connecting device and the circuit connecting device are arranged in the fixing device. The railway freight car automatic picking off and coupling up device of the present invention can realize the automatic picking off and coupling up of the railway freight car wind paths and the railway freight car circuits, and enables the picking off and coupling up work time to be shortened and the labor cost to be saved.
