Abstract
The invention relates to a release method of a permanent magnet lifting device. The method does not directly apply mechanical force to the external sucked object, but changes the magnetic circuit in the device to release the sucked object.
The present invention features that one movable magnetizer is added between the working magnetic poles of permanent magnetic hoisting device, that is, one magnetic circuit connected parallelly to the magnetic circuit of the outer sucked matter is added to reduce the magnetic flux of the outer heavy matter and release the heavy matter.
Description
The present invention relates to the method for releasing of permanent magnet hoisting device.
The delivery mode of permanent magnet hoisting device utilizes mechanical force to directly act on absorbate and makes its disengaging magnetic pole suction and blowing at present.This mode applicable surface is narrow, and blowing is undesirable.
The object of the present invention is to provide a kind of mechanical force of directly not using on extraneous absorbate, and at the inner magnetic circuit that changes of device, the method that absorbate is discharged.
Technical scheme of the present invention is: add mobilizable magnetizer between the work magnetic pole of permanent magnet hoisting device, promptly increase a magnetic circuit that is in parallel with extraneous absorbate magnetic circuit, make the actual magnetic flow that sends of permanent magnet directly be led go back to permanent magnet inside through this loop again, and the magnetic flux of process foreign objects seldom, be not enough to keep its adsorbed state, thereby weight is discharged.
Method of the present invention is simple, and practicality is reliable.
Fig. 1 is circular permanent magnet hoisting device scheme drawing; Among the figure: 1-body 2-permanent magnet 3-work magnetic pole 4-connecting rod 5-discharges ring 6-magnetic isolation plate
Fig. 2 is a rectangle permanent magnet hoisting device scheme drawing; Among the figure: the 7-release board
Figure A, figure B are release position, and figure a, figure b are for inhaling the thing state.
The invention will be further described below in conjunction with drawings and Examples.
Embodiment 1:
As shown in Figure 1, when discharging that ring (5) upwards rises to by connecting rod (4) and the magnetic pole of working (3) breaks away from or being about to break away from, between body (1) and the work magnetic pole (3) magnetic potential is arranged, when near the suction thing, can hold inhaling thing, when discharging ring (5) and make it fill space between work magnetic pole (3) and the body (1) downwards, the magnetic flow that sends from permanent magnet directly is directed to permanent magnet inside through discharging to encircle; At this moment, the magnetic force that the permanent magnet hoisting device produces to external world obviously reduces, and promptly is in release position, and weight is put down.
Embodiment 2:
Shown in figure A, a among Fig. 2, by some rectangle iron plates (original magnetic pole) permanent magnet is clipped together by certain orientation, form the essential part of rectangle permanent magnet hoisting device, release board (7) is set below original magnetic pole again, release board is made up of magnetic conduction bar (8) and NULL.Release board can move in the horizontal direction.When release board moves on to (shown in figure A) when making every magnetic conduction bar be in locus between each original magnetic pole,, thereby make extraneous absorbate release because the magnetic flow that permanent magnet sends has reduced magnetic flow by foreign objects through the magnetic conduction bar.When the release board translation makes magnetic conduction bar and original magnetic pole one by one to seasonable (shown in figure a), because of there is big magnetic potential difference in its two adjacent magnetic conduction bar, therefore bigger magnetic force is arranged to external world, be in the suction state.
Embodiment 3:
Shown in figure B, b among the figure, by some rectangle iron plates (original magnetic pole) permanent magnet is clipped together by certain orientation, below original magnetic pole, be provided with release board, under release board, be provided with and the corresponding working plate of original magnetic pole (9), working plate is fixed with respect to original magnetic pole, release board can be between original magnetic pole and working plate side travel, thereby reach the purpose that discharges and pick up weight.
Claims (1)
1, the method for releasing of permanent magnet hoisting device, promptly between the work magnetic pole of permanent magnet hoisting device, add mobilizable magnetizer, method with the break-make magnetic circuit, it is characterized in that: the iron plate (original magnetic pole) that has polylith that permanent magnet is clipped together in the inside of this device, below this iron plate by the release board of forming by many magnetic conduction bars (7), the working plate (9) fixing with respect to original magnetic pole arranged under the release board, and release board (7) moves between iron plate and working plate (9).
