Description
Technical field
The utility model relates to a kind of Jack, especially relates to a kind of automatic permanent magnetism hoisting jack.
Background technology
Existing permanent magnetic lifter for the ferrous materials handling generally comprises the permanent magnetic lifter of manual type and the permanent magnetic lifter of self acting.And the permanent magnetic lifter of self acting is subjected to liking of client deeply due to simple to operation.For example, disclosed a kind of by name in Patent Office of the People's Republic of China: " the adsorption magnetic force automatic switch device of magnetic-adsorption device " (patent No.: patent 99104882.2), between adjacent magnetic part in being arranged at main body, be provided with the rotary magnet that rotates by fixed magnets and axostylus axostyle.When action piece is upwards promoted, make the rotary magnet rotation by Ring gear and tooth bar, be relatively fixed magnet and rotary magnet become homopolarity, and magnetic part has magnetic force and object is held.This design rotates to change the magnetic pole of rotary magnet by the rack drives Ring gear, need not manual intervention, and is very easy to use.
But, because fixed magnets and the common material that adopts of rotary magnet are ferrites, because the ferritic magnetic attraction of unit volume is less, thereby want to increase the suction of magnetic-adsorption device, conventional way is that the volume that increases fixed magnets and rotary magnet is realized, but the increase that has also brought magnetic-adsorption device overall volume and weight simultaneously is difficult to apply.
Along with progress and the development of nd-fe-b technology, someone has expected that the stronger NdFeB material of magnetic attraction for the manufacture of fixed magnets and rotary magnet, wishing increases the suction of magnetic-adsorption device with this.Because both sides at rotary magnet are folded with rotating plate usually, gap between rotating plate and adjacent surface is usually less than 1 millimeter, when the rotary magnet that greatly strengthens when magnetic and fixed magnets are in the homopolarity state, can't realize rotation by the own wt of action piece because magnetic attraction makes rotary magnet between rotating plate and adjacent surface, have technical bottleneck.
Summary of the invention
The utility model provides a kind of rotary magnet and fixed magnets to be made by NdFeB material, Yi Bian between interior rotating plate and spaced walls or be folded with at least the automatic permanent magnetism hoisting jack of tourelle between the outer rotating plate inwall adjacent with body; The suction that exists in the solution prior art is little, bulky technical matters.
above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of automatic permanent magnetism hoisting jack, comprise the wheel word that body and its inside are provided with, be connected with the bont that can drive its rotation on wheel word, on wheel word and the both sides that are positioned at bont be respectively equipped with rotary magnet, interior rotating plate and outer rotating plate, rotary magnet is folded between interior rotating plate and outer rotating plate, be provided with spaced walls between described bont and interior rotating plate, on body and the both sides that are positioned at rotary magnet be provided with fixed magnets, it is characterized in that: described rotary magnet and fixed magnets are made by NdFeB material, at least on one side be folded with tourelle between described interior rotating plate and spaced walls or between the outer rotating plate inwall adjacent with body.During use, bont rises and drives simultaneously the wheel word rotation, and during due to beginning, the magnetic pole of rotary magnet and fixed magnets is opposite, at this moment, drives less can the realization of power of wheel word.After bont was raised to the top, wheel word driven rotary magnet had rotated 180 °, and rotary magnet and fixed magnets are made by NdFeB material, thereby when both reached homopolarity, under equal volume, suction of the present utility model strengthened greatly; By tourelle is set, make between interior rotating plate and spaced walls or inwall that outer rotating plate is adjacent with body between friction force change friction of rolling into by static friction, friction force reduces greatly, after using, can drive by the own wt of bont the wheel word rotation, the driven rotary magnet changes polarity, realizes automatically controlling.The utility model adopts NdFeB material to manufacture rotary magnet and fixed magnets, and between interior rotating plate and spaced walls or outside tourelle is set between the rotating plate inwall adjacent with body, small volume, suction are larger compared to existing technology.
As preferably, the lateral surface of described interior rotating plate and outer rotating plate is provided with the roller track corresponding with tourelle.Tourelle is limited in motion in roller track, makes structure comparatively stable.
As preferably, described tourelle is steel ball.Steel ball uses as tourelle, and is simple in structure, and result of use is good.Certainly, tourelle also can adopt roller or bearing to realize.
As preferably, described roller track for circular and with wheel word be the concentric setting.Roller track is circular, tourelle in roller track with the wheel word coaxial rotation, rotate smooth and easyly, resistance is less.
As preferably, described wheel word includes rotating shaft and is socketed in arm revolving gear in rotating shaft, and described bont comprises center plate, and the bottom of center plate is provided with tooth bar, and described tooth bar and arm revolving gear are intermeshing.Wheel word is connected being connected cooperation with arm revolving gear by tooth bar with bont, transmission is effective.
As preferably, the outer end of described wheel word and the outside that is positioned at body are provided with unidirectional locating wheel, and unidirectional locating wheel is provided with the ratchet-type embeded slot, and the lateral wall of described body is provided with the limiting stopper corresponding with the ratchet-type embeded slot.Ratchet-type embeded slot on unidirectional locating wheel and limiting stopper form and coordinate, namely form after making wheel word rotate 180 ° and locate, and after being used to complete, during the wheel word backward rotation, the ratchet-type embeded slot separates with limiting stopper.
Therefore, the utility model has following characteristics compared to existing technology: 1. adopt NdFeB material to manufacture rotary magnet and fixed magnets, and between interior rotating plate and spaced walls or outside tourelle is set between the rotating plate inwall adjacent with body, volume is little, suction is large; 2. roller track is set, and tourelle is limited in motion in roller track, and structure is comparatively stable; 3. wheel word is connected being connected cooperation with arm revolving gear by tooth bar with bont, and transmission is stable, effective.
