Abstract

The invention relates to a double-drive type hoisting permanent magnet, and belongs to hoisting equipment. The double-drive type hoisting permanent magnet comprises a lifting ring and a hoisting lifting chain, small lifting chains and swinging rods are connected, the swinging rods sleeve two driving shafts with clearances correspondingly, each set of driving ratchet wheel and pawl are symmetrically arranged in fork-shaped arms of the corresponding swing rod correspondingly, a driving cylindrical gear on the right side is meshed with a driven cylindrical gear on the right side, a driving cylindrical gear on the left side is meshed with a driven cylindrical gear on the left side, the driving cylindrical gear on the right side is meshed with the driving cylindrical gear on the left side, semicircular magnet yokes and iron-boron magnets form movable magnetic systems, a ferrite magnetic block is fixed between an outer magnetic yoke and an inner magnetic yoke to form a fixed magnetic system,each group of movable magnetic system is fixedly connected with two magnetic pole shafts correspondingly, the two groups of magnetic systems are arranged side by side and are separated by a middle separation plate in the middle. The double-drive type hoisting permanent magnet has the advantages that manufacturing, installation and maintenance are more convenient, the manufacturing cost is reduced, an anti-reversing device enables the work to be safer and more reliable, so that large-inclination-angle inclination resistance of the hoisting permanent magnet is realized, and the application range of the hoisting permanent magnet is widened.

Description

technical field [0001] The invention belongs to lifting equipment. Background technique [0002] In the prior art, Chinese patent CN107416662A discloses a double-arm driven lifting permanent magnet, but it still has certain shortcomings and deficiencies: first, in the actual installation process, due to the lack of reliable positioning references, the bevel gear The installation accuracy cannot meet the requirements, the damage rate of the bevel gear is high, and its normal operation cannot be guaranteed; second, when lifting an object with a large inclination angle, the lifting permanent magnet will slide down along the surface of the object because: When the heavy permanent magnet is working, the lifting permanent magnet must first be placed on the surface of the object to be sucked, and then the magnetic pole is flipped by pulling the pendulum by the small hanging chain and turning the ratchet to complete the adsorption process; in addition, in order to gather magnetism, ...
