Abstract
The utility model relates to a hoisting permanent magnet. The hoisting permanent magnet is provided with a rotating arm, a ratchet wheel, a pawl, a reverse pawl, a chain wheel chain transmission mechanism, and unit magnetic circuits. The hoisting permanent magnet is mainly characterized in that the unit magnetic circuits are composed of permanent magnets and magnetic poles. The unit magnetic circuits are many, and are mutually arranged and assembled together. The permanent magnet of each unit magnetic circuit can be driven by the transmission mechanism to rotate inside the magnetic pole. When the permanent magnet of each unit magnetic circuit rotates to an open circuit state, the permanent magnet of each unit magnetic circuit sucks materials; when the permanent magnet of each unit magnetic circuit rotates to a closed circuit state, the permanent magnet of each unit magnetic circuit discharges the materials. 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 magnetism conductive materials, and is the ideal hanging tool of the magnetism conductive materials.
Description
One, technical field:
The utility model relates to a kind of hoisting permanent magnet, particularly a kind of by some unit magnetic circuit form, can conversion the hoisting permanent magnet of magnetic circuit.
Two, background technology:
Industries such as big machinery, shipbuilding and metallurgy are mainly used lifting electromagnet, permanent magnet sucking hoisting apparatus, permanent magnetic lifter, steel rope and steel plate pincers to the carrying of iron and steel now.These instruments all have self unsurmountable shortcoming.The lifting electromagnet corollary equipment is many, the productive costs height, and power is big, and the energy consumption height runs into unexpected power failure, and absorbate falls down, and is dangerous; In a single day permanent magnet sucking hoisting apparatus is made, and its magnetic circuit is immutable, it can only lifting greater than the plate iron of pole surface, range of use is very little, and suction has only 1～5 ton; Permanent magnetic lifter is very little, can only lift by crane 0.1～1 ton, and range of use is littler, and steel rope and steel plate pincers are the most original and the way of old soil, its inefficiency, and labour intensity is big.
Three, summary of the invention:
The purpose of this utility model is to provide a kind of not electricity consumption, can replace a kind of permanent magnetism lifting instrument one lifting permanent magnet of former all handling iron and steel lifting tools again.
In order to realize this purpose, the utility model adopts the material of two permeability magnetic materials and non-magnetic conduction to be welded into an integral body, bore hole is processed into magnetic pole, be aided with semi arch strip shape pole shoe at the two poles of the earth of square permanent magnet, 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, bar magnet is contained in the magnetic pole, has so just formed the one unit magnetic circuit.Bar magnet can freely rotate in magnetic pole.When the permanent magnet magnetic field direction was horizontal, magnetic field was in open-circuit condition, externally manifested magnetic, produced the magnetic potential energy, and permeability magnetic material is produced attractive force; When the magnetic direction of permanent magnet was in vertical position, magnetic field was in closed circuit state, did not externally manifest magnetic, and is inoperative to any material.Utilize this characteristics, such unit magnetic circuit is assembled into the permanent magnetism lifting instrument of various different tonnages, i.e. hoisting permanent magnet according to certain rules.This hoisting permanent magnet utilizes members such as swivel arm, ratchet, ratchet, sprocket wheel, 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, make bar magnets all in this hoisting permanent magnet simultaneously according to the certain rules steering horizontal or vertically be the conversion magnetic circuit, so just reached purpose as the free suction of lifting electromagnet, discharging.
The concrete technical scheme of the utility model is: a kind of hoisting permanent magnet, have swivel arm, bearing, click, transmission device and unit magnetic circuit, it is characterized in that: by permanent magnet and magnetic pole component units magnetic circuit, the unit magnetic circuit is a plurality of, mutually permutation and combination together, the permanent magnet of each unit magnetic circuit can be driven by transmission device and rotate in magnetic pole.
Permanent magnet in the unit of the present utility model magnetic circuit is a square, two very the circular-arc pole shoe of magnetic conduction form bar magnet with non-magnet material, bearing is equipped with at two of bar magnet, one also is equipped with 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 has been owing to used later-model strong magnetic material, and it is little to have a volume, and suction is big, and discharging is convenient, and suction does not have impact, and 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 function of alternative lifting electromagnet, permanent magnet sucking hoisting apparatus, permanent magnetic lifter, steel rope and steel plate folder at normal temperatures.
