The invention aims to provide a rope pulling type automatic unhooking device. The rope pulling type automatic unhooking device mainly comprises a hook body, a rotating baffle shaft, a baffle block capable of rotating along with a rotating shaft, a movable pin, rotating wrenches, springs and the like, and mainly takes spring force, pulling force of a worker on the movable pin through a long and thin rope as well as the gravity of a lifted object as power sources. When the long and thin rope is tensioned, the movable pin upwards moves out of a pin hole, the rotating baffle shaft rotates under the action of torsional spring force, and the baffle block falls down to unhook lifting lugs of the lifted object. The rope pulling type automatic unhooking device is mainly used for realizing the function that an operator can perform unhooking release operation on an underwater vehicle ashore or aboard certain distance away from the vehicle when the underwater vehicle is lifted, the condition that the operator goes into the sea for close operation is avoided, and the safety of the operator is guaranteed.
