The invention discloses a porcelain bushing hook device and belongs to the field of hoisting equipment in construction of an electric power system. The present porcelain bushing hoisting device for mutual inductors has the problem that an external insulating layer of a porcelain bushing is easily damaged, the holding force is inadequate and the hoisted porcelain bushing is easy to fall off. The porcelain bushing hook device comprises clamping elements (1) which are hinged to form a scissors shape; each clamping element (1) comprises a straight force application section (3) and an arc-shaped clamping section (4); the straight force application sections (3) are hinged between movable connecting plates (5); connecting rings (6) sleeve the upper parts of two movable connecting plates (5); the other ends of two connecting rings (6) sleeve a circular ring connector (7); the straight force application sections (3) are fixedly connected with porcelain bushing hooks (8) which are buckled. By adopting the porcelain bushing hook device, possibility of damaging the porcelain bushing can be reduced and fall-off possibility of the bushing during the hoisting process of the bushing is avoided, thus insulation strength of the bushing is improved and safety of installation, construction and maintenance processes is improved.
