Description
Technical field
The present invention relates to electromagnetism ground jack technical fields, it particularly relates to a kind of energy-saving mechanical handling electromagnetism lifting
Device.
Background technology
Since WALKER companies in the U.S. have manufactured magnechuck at the end of the 19th century, transport operation has been carried out to ferrimagnet
The history that experienced more than 100 years is especially applied in workshop with the expansion of application range, the shortcomings that just having showed him；Consumption
It can greatly (such as the sucker of a suction 16t needs electric power about 10kW)；More important is once powering off, sucker loss of excitation causes workpiece
It falls.Although matched can be used now with power-off protection apparatus, this device can only protection power source power failure, can not protect
Protect the failure of energized circuit.
In the 1930s, BRAILON companies of France start permanent-magnet material to be applied on sucker, energy consumption and heat are being reduced
Deformation, safe and reliable aspect have good effect, make troubles to operation, to limit it in terms of handling heavy steel plate
Development.
TECNOMAGNETE companies of Italy in 1974 have manufactured electric permanent-magnet suction disc, so-called electric permanent-magnet suction disc with magnetic variation principle
Permanent magnetic chuck is controlled using electric pulse, since conduction time is short, energy consumption and fever all very littles；Again due to leaning on permanent-magnet material as magnetic
Source, there is no power-off losss of excitation to cause the danger that workpiece is fallen, so relatively safety, only because lacking high performance permanent magnetism at that time
Material, to fail extensive use.

Effect is undesirable；3. requiring strictly lifting operation, lifting face must be bonded completely with absorbate could safe lifting；4. mostly using
Rubidium iron boron magnetic patch, therefore involve great expense.
201410021731.4 Xiangshan Wei Huici industry Co., Ltd of Chinese patent discloses a kind of electric permanent magnet, passes through change
It is passed through the electric current of coil block, you can realize the superposition or disappearance of magnetic field intensity on workbench；The entire work period, which only inhales, to put
Expect power consumption, belongs to super short time duty, it is very energy saving.
201410326810.6 Jiangsu Ci Gu Science and Technology Co., Ltd. of Chinese patent discloses a kind of electric-controlled permanent magnetic chuck,
Rotation magnetic patch polarity is driven by motor, realizes the superposition or counteracting of magnetic field intensity.Service life is long, safe and reliable, belongs to super
Short time duty, it is very energy saving.
Although electric control permanent magnet was obtained with electric permanent magnet and is constantly progressive in recent years, solves permanent magnetism lifting the degree of automation
Not high problem, and magnetic is not shown in off working state, securely and reliably；But still has the shortcomings that the most of of permanent-magnet type, such as inhale
Power is inadequate, undesirable to steel scrap, shaped steel, bar and high-temperature material (300 DEG C of ＞) using effect, requires lifting same tight
Lattice drop off hidden danger, involve great expense (more expensive 40%-80% than traditional lifting electromagnet).
