Abstract
The utility model relates to a lifting permanent-magnet, comprising a lifting chain, a ratchet wheel, a detent, a driving mechanism and a unit magnetic path which is composed of a permanent magnet and magnetic poles. The permanent magnet of each unit magnetic path can be driven by the driving mechanism to rotate in the unit magnetic path. The utility model is characterized in that the driving mechanism is a group of roller chains and sprocket wheels which is driven by the detent and the ratchet wheel; the permanent magnet in the unit magnetic path is in the shape of a square; the two poles is additionally provided with circular arc-shaped pole shoes; the magnetic poles are also in the shape of a circular arc. The utility model has the advantages of small size, large suction force, conveniently unloading, material sucking without impact, no special requirement to conducting magnetic materials, lower cost, high energy saving, etc.
Description
The utility model relates to a kind of hoisting permanent magnet, refers in particular to the hoisting permanent magnet of energy conversion magnetic circuit.
The utility model is in the patent of my application in 93 years " permanent magnet sucking hoisting apparatus of energy conversion magnetic circuit " unit magnetic structure of (patent No. ZL:93234951) and the once improvement on the whole driving device." permanent magnet sucking hoisting apparatus of energy conversion magnetic circuit " has many advantages than original permanent magnet sucking hoisting apparatus and lifting electromagnet, and volume is little, suction is big, discharging is convenient, and suction does not have impact, and the magnetic conduction material is not had specific (special) requirements, and productive costs is lower, high energy saving etc.But, because it is the multi-stage gear transmission, gear and pick-off gear and tooth bar requirement on machining accuracy height, transmission ratio reduces, and relative cost is higher, and difficulty of processing is big, two magnetic poles are circular-arc rectangular permanent magnet, be difficult to after the shaping magnetize, and can not carry out machinework behind magnetic.
The purpose of this utility model is, the unit magnetic structure and the driving device of above patent once improved.
The technical solution of the utility model is such, will the permanent magnet sucking hoisting apparatus of magnetic circuit " can conversion " use two very the strip permanent magnet of circular arc change the square permanent magnet into, two magnetic poles are aided with semi arch strip shape pole shoe, make it still to become one the two very permanent magnet of the strip shape of circular arc, with the magnetic pole and the non-magnetic inductive block component units magnetic circuit of two semi arches, it can be rotated equally in the unit magnetic circuit.
Utilize transmission devices such as ratchet, ratchet, chain, sprocket wheel, replace transmission devices such as employed gear, reverse wheel and tooth bar in " permanent magnet sucking hoisting apparatus of energy conversion magnetic circuit ".The lifting of hoisting crane and the descend power give and the power motion or other external force effect under and Motion Transmission to permanent magnet, make the inner all permanent magnets of the utility model simultaneously according to certain rule steering horizontal or vertical (being the conversion magnetic circuit), when permanent magnet is in vertical position when being position shown in Figure 5, magnetic circuit is in closed state, it is the magnetic circuit short circuit, externally leakage field is minimum, shows magnetic hardly.When permanent magnet the two poles of the earth were horizontal, magnetic circuit was in open-circuit condition, and the two poles of the earth manifest magnetic, produced the magnetic potential energy, and the magnetic conduction material is produced suction.So just can reach purpose as " permanent magnet sucking hoisting apparatus of energy conversion magnetic circuit " free suction discharging.Utilize these characteristics the unit magnetic circuit can be assembled into the hoisting permanent magnet of various different tonnages according to certain rule.

Accompanying drawing 4 is Fig. 2 B-B cutaway view
Accompanying drawing 5 is Fig. 2 C-C cutaway view
An embodiment is described below with reference to the accompanying drawings.Permanent magnet 18, circular-arc magnetic inductive block 19 is a pole shoe, forms the one unit magnetic circuit with magnetic pole 17 and non-magnetic inductive block 20, and the permanent magnet bipolar shoe is circular-arc, and magnetic pole also is circular-arc, and is corresponding with the unit magnetic circuit.Driving chain wheel 15 and roller chain 14 are set, permanent magnet is rotated between two magnetic poles.Chain 1 is the connecting bridge of hoisting permanent magnet and hoisting crane, climb on the fork 2 ratchet 3 is housed, promote ratchet 4 by lifting action ratchet 3, the torque that ratchet 4 produces passes to two drive sprockets 9 by the imput shaft on the bearing 5 11, be transferred to driven sprocket 13 by chain 6 again, drive sprocket wheel 7 by axle 12, sprocket wheel 7 drives chain 14, chain 14 drives the sprocket wheel 15 on the permanent magnet in the unit magnetic circuit, makes the permanent magnet of unit magnetic circuit produce the rotation that zero degree to nine ten is spent.So just can make the closed circuit open circuit that becomes of unit magnetic circuit, form the magnetic system of whole hoisting permanent magnet, externally produce the magnetic field boundary, reach the purpose of inhaling fortune magnetic conduction material.
