The present invention provides a railway freight car wind path automatic picking off and coupling up device. The railway freight car wind path automatic picking off and coupling up device comprises a fixing device connected with car couplers and a wind path connecting device arranged in the fixing device, and the wind path connecting device is connected with the air ducts, connects the wind paths automatically under the action of the external forces contacted with the fixing device when the two car couplers are coupled up and blocks the wind paths automatically when the external forces disappear. The railway freight car wind path automatic picking off and coupling up device of the present invention can realize the automatic picking off and the coupling up of the railway freight car wind paths, enables the picking off and the coupling up work time to be shortened, the labor cost to be saved and the shunting efficiency of the operating personnel to be improved.
