Abstract
The utility model relates to a double magnetic source permanent-magnet electromagnetic suction lifting device, comprising magnetic poles, permanent-magnetic steel and magnetized coils. The utility model is characterized in that the suction lifting device adopts the permanent-magnetic steel with two different kinds of magnetic characteristics; one is the permanent-magnetic steel (permanent-magnetic source) without variable polarity; the other one is the permanent-magnetic steel (alternating magnetic source) with variable polarity; the magnetized coils are arranged on the surrounding of the permanent-magnetic steel with variable polarity. The utility model changes the direction of magnetic flux through changing the direction of current in the magnetized coils, being designed and formed according to the theory of the positive and the opposite magnetization of the magnetized coils and the superposition of magnetic fields. The utility model has the advantages of practicality, reliability and high iron sucking ratio.
Description
The utility model relates to a kind of permanent-magnetism electromagnetic suction hanging device.
The permanent-magnetism electromagnetic suction hanging device is kept absorption to absorbate by the remanent magnetism of permanent-magnet steel, and is safe and reliable.Many enterprises are studied it.Its major technique has following two kinds: the one, adopt the permanent-magnet material of high-remanence low-coercivity, and with the suction of magnetizing of big electric current, with the anti-degaussing blowing of little electric current, it is definite that its shortcoming is that demagnetizing current is difficult to, and blowing is unreliable, and the higher (1:6～1:10) than not of suction iron.The 2nd, adopt permanent-magnet material to be divided into two groups with a kind of high-remanence low-coercivity, magnetize to change the wherein polarity of one group of permanent-magnet material with identical big electric current is positive and negative, it is identical or finish lifting or blowing on the contrary to make it polarity with another group permanent-magnet material, its shortcoming be the polarity chron that changes one group of permanent-magnet material often another group also change together and do not have a practical value.
The purpose of this utility model be to provide a kind of practicality reliable, inhale iron than high permanent-magnetism electromagnetic suction hanging device.
The technical solution of the utility model is: the permanent-magnet steel that adopts two kinds of different magnetic characteristics, a kind of is immutable polarity permanent-magnet steel (permanent magnetic source), but another kind is Variable Polarity permanent-magnet steel (an alternation magnetic source), but around the Variable Polarity permanent-magnet steel coil that magnetizes is set.The coil that magnetizes is in order to magnetize to but the Variable Polarity permanent-magnet steel is positive and negative.
The utility model magnetizes by change, and the direction of DC current can change its flow direction in the coil.When but the flow direction of the magnetic flux of immutable polarity permanent-magnet steel and Variable Polarity permanent-magnet steel was identical, mutual superposition produced resultant flux, by the magnetic pole combined action in absorbate.Resultant flux is zero externally not show magnetic during opposite and equal and opposite in direction when both flow directions, discharges absorbate.Magnetize coil only in lifting or discharge the moment energising, and in the handling process, rely on the high remanent magnetism of permanent-magnet steel to keep absorption absorbate.Practical reliable, inhale iron than high.
Fig. 1 is the utility model master cutaway view;
Fig. 2 is the left view of Fig. 1.
Below in conjunction with most preferred embodiment of description of drawings.
But the utility model is made up of nonferromagnetic cover plate 1, ferrimagnetism magnetic pole 2, immutable polarity permanent-magnet steel 3, the coil 4 Variable Polarity permanent-magnet steels 5 that magnetize.Immutable polarity permanent-magnet steel 3 is arranged on the below of nonferromagnetic cover plate 1, but Variable Polarity permanent-magnet steel 5 is arranged on the below of immutable polarity permanent-magnet steel 3, but is the coil 4 that magnetizes around the Variable Polarity permanent-magnet steel.By model machine of this design trial-production, deadweight 180kg passes through trail run, its maximum safe lifting weight can reach 4000kg(and inhale iron than being 1:22), lifting weight is 2000kg under the normal circumstances, and minimum release weight is almost nil, and is also littler than the minimum release weight of general lifting electromagnet.
Claims (2)
1, a kind of double magnetic source permanent-magnetism electromagnetic suction hanging device, have magnetic pole, permanent-magnet steel and the coil that magnetizes, it is characterized in that adopting the permanent-magnet steel of two kinds of different magnetic characteristics, a kind of is immutable polarity permanent-magnet steel, it is permanent magnetic source, but another kind is the Variable Polarity permanent-magnet steel, i.e. alternation magnetic source, but the coil that magnetizes be arranged on the Variable Polarity permanent-magnet steel around.
2, suction hanging device according to claim 1 it is characterized in that immutable polarity permanent-magnet steel is arranged on the below of nonferromagnetic cover plate, but the Variable Polarity permanent-magnet steel is arranged on the below of immutable polarity permanent-magnet steel.
