Jig frame device for transporting and installing offshore wind power tower drum

The utility model discloses a jig frame device for transporting and installing an offshore wind power tower drum. The jig frame device comprises a tool flange plate mechanism, a rolling shaft mechanism, a bottom bearing platform mechanism and a limiting mechanism. The tool flange plate mechanism is provided with a fastening part used for being matched with a screw hole in the bottom of a wind power tower. The rolling shaft mechanism is fixedly arranged on the side, away from the wind power tower drum, of the tool flange plate mechanism, and the rolling shaft mechanism is used for enabling the wind power tower drum to rotate around the rolling shaft mechanism; the bottom end of the bottom bearing platform mechanism is placed on a deck, and the top end of the bottom bearing platform mechanism is fixedly connected with the end of the rolling shaft mechanism. The limiting mechanism is arranged between the tool flange plate mechanism and the bottom bearing platform mechanism and used for limiting the wind power to
