Title:
MAGNETIC LIFTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/211194
Kind Code:
A1
Abstract:
The present invention relates to a magnetic lifting device capable of adjusting the magnetic force by controlling the rotation angle of a rotating permanent magnet by means of a worm gear, and capable of substantially blocking the rotational force of the rotating permanent magnet to return to the original place, when in an unstable state. To this end, the present invention comprises: a fixed permanent magnet; a first pole piece coming into contact with the N pole of the fixed permanent magnet and having an applied surface; a second pole piece, which is disposed to be opposite the first pole piece, coming into contact with the S pole of the fixed permanent magnet and having an applied surface; the rotating permanent magnet coupled to be rotatable between the first pole piece and the second pole piece; and a worm gear connected to a rotating shaft of the rotating permanent magnet to be able to rotate the rotating permanent magnet, the worm gear having a worm wheel connected to the rotating shaft and a worm coupled to the worm wheel.
