PURPOSE: A multi-type adjustable magnetic coil lifter is provided to minimize the damage of an attached object since symmetrically arranged magnetic poles are attached to the outer surface of the attached object. CONSTITUTION: A multi-type adjustable magnetic coil lifter comprises a housing, a central body, a side body, a plurality of poles(130,140), a lift, a rotating unit and a sensing unit(180). The central body is connected to the center of the housing. The side body is connected to both sides of the housing to be hinge-rotated. The poles are arranged on the central body and the side body, comprise curved parts(132), which make contact with the outer surface of a cylindrical attached-object, and attach/detach the attached object by the magnetic force. The lift ascends/descends the poles. The rotating unit rotates the housing. The sensing unit senses the rotating angle of the housing. The pole of the central body is lifted and the side body is hinge-rotated in the housing. |
