Abstract
The utility model relates to a reciprocating magnetic circuit hoisting permanent magnet. The reciprocating magnetic circuit hoisting permanent magnet is provided with a rotating arm, a support seat, a ratchet wheel, a pawl, a transmission mechanism, and unit magnetic circuits. The reciprocating magnetic circuit hoisting permanent magnet is characterized in that Magnetic poles, fixing permanent magnets, and movable permanent magnets are together form the unit magnetic circuits. The unit magnetic circuits are many, and are mutually arranged and assembled together. The movable permanent magnet of each unit magnetic circuit can be driven by the transmission mechanism to rotate inside the magnetic pole. When the magnetic field directions of the movable permanent magnets and the magnetic field directions of the fixing permanent magnets are identical, the reciprocating magnetic circuit hoisting permanent magnet presents magnetism towards outside, and generates suction force to a magnetism conductive material. When the magnetic field directions of the movable permanent magnets and the magnetic field directions of the fixing permanent magnets are opposite, the reciprocating magnetic circuit hoisting permanent magnet does not present the magnetism towards the outside, and does not generate the suction force towards the outside. The utility model has small volume, large suction force, convenient material suction and discharge, low production cost, and high energy saving; the utility model has no special need to the magnetism conductive material, and is the ideal hanging tool of the magnetism conductive material.

In order to realize this purpose, the utility model is welded into an integral body with the material of two permeability magnetic materials and non-magnetic conduction, be processed into magnetic pole according to certain process, be aided with semi arch strip shape pole shoe at the two poles of the earth of square permanent magnet forever, make it still to become one the two very permanent magnet of the strip shape of circular arc, two forms a bar magnet with the non-magnetic material welding processing.Bar magnet two dress bearing, duplex chain wheel is equipped with in the other end, and bar magnet is contained in the magnetic pole, can freely rotate.Adorn a fixed permanent magnet in the magnetic pole in addition, two magnetic source, fixed permanent magnet and movable permanent magnet are just arranged in the magnetic pole like this, when the magnetic pole of the magnetic pole of movable permanent magnet and fixed permanent magnet is identical, homopolarity repels, magnetic line of force is external, produce magneto motive force between magnetic pole, externally manifest magnetic, the magnetic conduction material is produced suction; When the magnetic pole of the magnetic pole of movable permanent magnet and fixed permanent magnet was opposite, inhaled mutually at the two poles of the earth, and the magnetic line of force inner loop does not externally show magnetic, and is inoperative to any material, so just formed independent one unit magnetic circuit.Utilize this characteristics, such unit magnetic circuit is assembled into the permanent magnetism lifting instrument one compound magnetic circuit hoisting permanent magnet of various different tonnages according to certain rules.This lifting electromagnet utilizes mechanism's parts such as swivel arm, ratchet, ratchet, chain, the hoisting force of hoisting crane and the descend power give and the power motion or other external force effect under and Motion Transmission to bar magnet, making bar magnets all in this hoisting permanent magnet turn to homopolarity or heteropole according to certain rules simultaneously is the conversion magnetic circuit, has so just reached the purpose of freely inhaling discharging as lifting electromagnet.
The concrete technical scheme of the utility model is: a kind of compound magnetic circuit hoisting permanent magnet, have swivel arm, bearing, click, transmission device and unit magnetic circuit, it is characterized in that: by magnetic pole and fixed permanent magnet and the movable common component units magnetic circuit of permanent magnet, the unit magnetic circuit is a plurality of, mutually permutation and combination together, the movable permanent magnet of each unit magnetic circuit can be driven by transmission device and rotate in magnetic pole.
Fixed permanent magnet in the unit of the present utility model magnetic circuit and movable permanent magnet are box-shaped, the semicircle pole shoe of magnetic conduction is equipped with at the two poles of the earth of movable permanent magnet, and become bar magnet with the non-magnet material welding processing, and bearing is equipped with at bar magnet two, and one also is equipped with the duplex chain wheel.
Transmission device of the present utility model is the sprocket wheel link chain mechanism, and its sprocket wheel rotates with the rotation of swivel arm and by the rotation of the ratchet on the bearing.
Unit of the present utility model magnetic circuit is connected by duplex chain, synchronized operation during transmission.
In order to reduce the error of chain gear, the utility model is provided with two swivel arms, two bearings, two cover clicks, two overlap messenger chains.
In order to make transmission each time more reliable, anti-ratchet is housed also on bearing.
The utility model uses unit magnetic circuit magnetic field superposition owing to used later-model strong magnetic material, and therefore, it is little that this hoisting permanent magnet has a volume, suction is big, and discharging is convenient, and suction does not have impact, permeability magnetic material is not had specific (special) requirements, and productive costs is lower, characteristics such as energy savings.Therefore can be used in of absorption and the handling of places such as mine, harbour, factory, warehouse, station widely to different magnetic material.Reach the effect of alternative lifting electromagnet, permanent magnet sucking hoisting apparatus, permanent magnetic lifter, steel rope and steel plate pincers at normal temperatures.
