A magnetic circuit horizontal rotating lifting permanent magnet

Abstract

The invention provides a magnetic path horizontal rotary type hoisting permanent magnet. The magnetic path horizontal rotary type hoisting permanent magnet is mainly composed of three parts, namely a mechanical rotation part, a magnetic system body and a control device, and is characterized in that a lifting ring of the mechanical rotation part is arranged on a lifting rod with a hook; when the lifting rod with the hook slides in a lifting rod slide rail, left and right lifting bars and large bevel gears are driven to rotate, then small bevel gears are driven to horizontally rotate, and finally, a plurality of rotary magnetic shafts in the magnetic system body are driven to rotate by a roller chain so as to change a magnetic path; and each lifting or descending of the lifting rod with the hook is used for controlling the unhooking or the hooking of the hook, so that the rotary angles of the magnetic shafts in the magnetic system body are controlled to control the circulation of two states, namely iron suction and iron releasing, of the hoisting permanent magnet; and a ratchet wheel is not used so that the problems of an old type hoisting permanent magnet that the iron suction is not synchronous, the machining is difficult and the like are completely overcome.

Description

technical field [0001] The invention relates to the technical field of lifting permanent magnets, in particular to a magnetic circuit horizontally rotating lifting permanent magnet. Background technique [0002] At present, the self-unloading lifting permanent magnet on the market (patent number: 200420035640.8, patent number: 200420035639.5) is lifted up and down by the left and right two sets of hoists on the magnetic body, respectively driving the corresponding pawl and ratchet group to rotate, and driving the side magnetic pole chain The wheel rotates, and then drives the fixed-angle circular rotation of the side magnetic poles, so that the magnetic circuits can cancel each other or superimpose each other to realize the sequential cycle of suction and discharge. Its main disadvantages: [0003] 1. Since the ratchet cannot be locked, when the suction capacity reaches the limit, the magnetic force will push the ratchet to rotate and unload automatically, which poses a ver...

AI Technical Summary

Problems solved by technology

[0003] 1. Since the ratchet cannot be locked, when the suction capacity reaches the limit, the magnetic force will push the ratchet to rotate and unload automatically, which poses a very large installation hazard;

[0004] 2. It is easy to appear that the left and right ratchets and pawls are not synchronized, and the phenomenon of left rotation and right non-rotation occurs, which affects the performance;

[0005] 3. The side rotation of the magnetic circuit requires a lot of yokes, high processing roughness requirements, and difficult maintenance and assembly;

[0006] 4. When lifting multiple parallel square steel billets, the length of the rotating magnetic core is required to be long, and the processing of the side rotating magnetic yoke and rotating magnetic poles is very difficult or even impossible.
