FIELD: apparatuses with permanent magnets. SUBSTANCE: apparatus includes magnetic block having working surface, lengthwise and crosswise symmetry axes and with removing mechanism. Magnetic block includes two power rods arranged at different sides relative to its lengthwise symmetry axis, mounted on the same axis laid in plane normal relative to lengthwise symmetry axis of magnetic block and dividing magnetic block by larger and smaller portions. Removing mechanism includes ¤-shaped bracket having in its upper flange rectangular groove and through openings in lateral flanges. Power rods of magnetic block are passed through said through openings. Bracket embraces magnetic block in such a way that its upper rectangular groove is arranged at side of smaller portion of magnetic block. Depth of said rectangular groove is equal to sum of height of magnetic block and height of removal of magnetic block; width of said rectangular groove is equal to inner distance between lateral flanges of bracket. Spacing between axes of power rods and lower plane of upper flange of bracket is less than spacing between axis of power rods and edge of magnetic block at side of its smaller portion. Spacing between axis of through opening of lateral flange of bracket and edge of its lateral flange at side of smaller portion of magnetic block is equal to sum of distance along height from axis of power rods until working surface of magnetic block and height of removing magnetic block. Removing mechanism also includes handle whose free end is arranged at side of larger portion of magnetic block. Handle is secured to upper flange of bracket. EFFECT: enhanced efficiency of apparatus. 2 cl, 3 dwg |
