The invention relates to a tower crane standard knot bolt fixing device which is arranged outside a bolt on a tower crane standard knot. The tower crane standard knot bolt fixing device comprises a fixing ring and fasteners, wherein the inner diameter of the fixing ring is polygonal and is larger than the outer diameter of the bolt on the tower crane standard knot; a plurality of through holes areformed in the side surface of the fixing ring and are used for mounting the fasteners in a matching manner; the fasteners are used for reinforcing the bolt; the fixing ring is connected to the outerside of the bolt in a sleeving manner during mounting; two through holes are formed in the side surface of the fixing ring; the fasteners are arranged in the through holes and penetrate through the through holes; and the bolt is fastened by rotating the fasteners from the outside. The tower crane standard knot bolt fixing device has the advantages that the tower crane standard knot bolt fixing device is mounted on the bolt, close to the outer side, in the tower crane standard knot bolt, so that the device is tightly attached to the tower crane standard knot, and the aim of limiting the rotation of the bolt is fulfilled.
