The invention provides an electromagnetically-driven helicopter cargo hook device. The electromagnetically-driven helicopter cargo hook device comprises a rack, a left swing arm, a limiting block, a left hook frame, a right swing arm, a right hook frame, a limiting mechanism and a driving piece. The left swing arm is arranged above the left hook frame; the right swing arm is arranged above the right hook frame; one end of the left swing arm is mounted on the rack through a left swing arm shaft; the limiting block limits the rotating angle of the left swing arm; one end of the right swing arm is hinged with the other end of the left swing arm through a rotating shaft; the other end of the right swing arm is hinged to the top end of the right hook frame through a right swing arm shaft; the right hook frame is installed on the right side of the rack through a right hook frame shaft; the left hook frame is installed on the left side of the rack through a left hook frame shaft; the lower portion of the right hook frame is an L-shaped short hook; and the L-shaped short hook is in lap joint with the tail end of the left hook frame to form a goods bearing area. The limiting mechanism limits swinging of the rotating shaft, and the driving piece drives the limiting mechanism to release limitation on the rotating shaft, so that the left hook frame and the right hook frame release goods. The device is simple in structure, high in reliability, easy to disassemble and maintain, light in weight and low in cost.
