Abstract

This utility model is related to a kind of permanent magnet hoisting magnetic leakage free sucker, and it mainly includes yoke, every magnet, permanent magnet, coil;Described yoke totally two, including left yoke, right yoke, and symmetrical distribution;Described every magnet totally two, including on every magnet, under every magnet, and in being distributed up and down;Described yoke inner surface forms circular cavity with every magnet inner surface;Described coil is nested in described permanent magnetism external surface, and rotates in the range of 90 ° of circular cavity with described permanent magnet.This device not only enables that lifting steel scrap is safe and reliable, unload carried convenient, and can eliminate the leakage field of chuck surface.

Description

A kind of permanent magnet hoisting magnetic leakage free sucker
Technical field
This utility model is related to lifting magnet sucker and in particular to a kind of permanent magnet hoisting magnetic leakage free sucker.
Background technology
Lifting magnet can be divided into electromagnetism lifting and two kinds of permanent magnet hoisting, respectively has pluses and minuses, but present permanent magnet hoisting practicality By force, more favored.The ultimate principle of permanent magnet hoisting suction cup is:It is not necessary to galvanization in inhaling weight transportation, by permanent magnet Powerful magnetic force gets up steel scrap lifting, there is not occurring security incident because of power failure simultaneously.Therefore, compare traditional electricity Magnetic lifting, the great advantage of permanent magnet hoisting is energy-conservation, safe and reliable.
But, permanent magnet lifting device also has some defects.For example, due to rotating permanent magnet, most of magnetic flux is shorted, and Without magnetic work such as steel scraps thus reaching unloading purpose.But, there is small part leakage field, the little ferrum on its surface in chuck surface Bits can not be unloaded clean, and when causing sucker to use, its magnetic force can be cut down next time.This is one and puts urgent need solution in the field of business Problem is although domestic had some solutions, but the speed of its unloading is slower, and efficiency is low.
A improved permanent magnet hoisting suction cup is therefore developed on market be very important.
Content of the invention
Main purpose of the present utility model is to provide a kind of permanent magnet hoisting magnetic leakage free sucker, and this utility model enables lifting Steel scrap is safe and reliable, unload carried convenient, and can eliminate chuck surface leakage field it is ensured that its surface no iron filings.
For reaching above-mentioned purpose, this utility model takes technical scheme below:A kind of permanent magnet hoisting magnetic leakage free sucker, its bag Include yoke, every magnet, permanent magnet, coil;Described yoke totally two, including left yoke, right yoke, and symmetrical distribution; Described every magnet totally two, including on every magnet, under every magnet, and in being distributed up and down;Described yoke inner surface with magnet Surface forms circular cavity;Described coil is nested in described permanent magnet surfaces, and with described permanent magnet in 90 ° of scopes of circular cavity Interior rotation.
Wherein, described left yoke and right yoke are connected every magnet;The axis of described coil and the dead in line of permanent magnet.
The utility model has the advantage of:Permanent magnet hoisting magnetic leakage free sucker of the present utility model passes through to arrange one group of rotation Permanent magnet and coil, when permanent magnet and coil rotate 90 °, and with when the magnet perpendicular contact, achievable steel scrap by fast discharging, Pass to certain reverse dc so as to the electromagnetic field that produces is offsetting the stray field of permanent magnet generation it is ensured that permanent magnetism simultaneously Hoisting suction cup surface magnetic leakage free.

Fig. 2 inhales for this utility model and carries steel scrap entirety cross section structure diagram.
Fig. 3 is this utility model unloading steel scrap entirety cross section structure diagram.
Specific embodiment
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Referring to figs. 1 to Fig. 3, this utility model provides a kind of permanent magnet hoisting magnetic leakage free sucker, and it mainly includes:Including magnetic Yoke(1), every magnet(2), permanent magnet(3), coil(4);Described yoke(1)Totally two, including left yoke(11), right yoke (12), and symmetrical distribution;Described every magnet(2)Totally two, including on every magnet(22), under every magnet(21), and be in It is distributed up and down;Described yoke(1)Inner surface with every magnet(2)Inner surface forms circular cavity;Described coil(4)It is nested in described Permanent magnet(3)Surface, and with described permanent magnet(3)Rotate in the range of 90 ° of circular cavity.
Referring to figs. 1 to Fig. 3, described every magnet(2)Connect left yoke(11)With right yoke(12);Described coil(4)Axle Line and permanent magnet(3)Dead in line.
Operation principle of the present utility model is as follows:Work as permanent magnet(3)And coil(4)When going to Fig. 2 position, coil(4)No Energising, permanent magnet(3)The magnetic line of force producing passes through steel scrap(5)Form closed-loop path, now for inhaling load state.Work as permanent magnet(3) And coil(4)When going to Fig. 3 position, permanent magnet(3)The most of magnetic line of force producing is by every magnet(2)Block, and without useless Steel(5), simultaneously unloaded clean in order to ensure the iron filings of chuck surface, for coil(4)Pass to certain reverse dc, Electromagnetic field that it produces is made to offset permanent magnet(3)The stray field producing, now for unloaded state.
The foregoing is only preferred embodiment of the present utility model, not thereby limit patent of the present utility model, every The equivalent structure made using this utility model description and accompanying drawing content or equivalent flow conversion, or be directly or indirectly used in Other association areas, are all included in the same manner in scope of patent protection of the present utility model.
