The invention discloses an automatic unhooking device of a subinclined shaft upper yard. The automatic unhooking device comprises an automatic unhooking structure and an automatic hook moving structure. The automatic unhooking structure comprises unhooking rack fixing beams. An unhooking rack is fixed by the two unhooking rack fixing beams. A hanging ring moving slideway is arranged in the unhooking rack. A hanging ring with a pulley moves in the hanging ring moving slideway. A hook is connected with a connecting pin through a ring chain. The unhooking device further comprises a ring type connecting device connected through a lifting steel wire rope. The automatic hook moving structure comprises a connecting steel wire rope. One end of the connecting steel wire rope is connected with a traction pulley, and the other end thereof is connected with counter weight. The connecting steel wire rope changes directions through a guide pulley. The lifting steel wire rope penetrates the traction pulley and is pressed on the same. The automatic unhooking device has the advantages that automatic unhooking is achieved, automatic hook moving is achieved to create conditions for next-step hook connecting, and the device is simple in structure, safe and reliable, and convenient to mount and manufacture.
