The shortcoming of most magnetic levitation system of the prior art is complex structure, and control operation complexity and system be easy care not.
The utility model content
The purpose of this utility model is the above-mentioned shortcoming that overcomes original levitation device, a kind of magnetic suspension lowering or hoisting gear is provided, this device uses a fulcrum bar of the spring supporting movement platform, the size of coming the suffered Ampere force of controlled motion platform by the size of electric current in the control square coil, so the adjustable height of motion platform is only determined by electric current.
The utility model is achieved through the following technical solutions, and the utility model comprises: pedestal, two block permanent magnets, two U type magnetic conductors, square coil, fulcrum bar of the spring, motion platform.The two block permanent magnet S utmost points are fixed together with two any side inwalls of U type magnetic conductor respectively, form two U type permanent magnets, the magnetic line of force of this U type permanent magnet is pointed to the opposite side inwall of U type magnetic conductor by the N utmost point of permanent magnet, two U type permanent magnet symmetries are fixed on the center on pedestal both sides, fulcrum bar of the spring supporting movement platform, square coil is fixed on the center of motion platform bottom, and two minor faces of square coil expose, and two U type magnetic conductors pass two minor faces of square coil respectively.
One end of described fulcrum bar of the spring is fixed on the pedestal center, and the other end is fixed on the motion platform center.
The initial position of described square coil is positioned at the center of U type magnet structure short transverse.
Two minor face exposed portions serve equal in length of described square coil.
Two minor faces of described square coil equate at interval with distance between two U type magnetic conductors.
The utility model enough keeps the stable of motion platform with fulcrum bar of the spring supporting movement platform, the hardness of fulcrum bar of the spring, makes motion platform have the lifting degree of freedom again.At first square coil is switched on during work.When square coil feeds electric current, place the energising square coil in U type magnetic field that permanent magnet produces to be subjected to the effect of Ampere force, according to the polarity of U type permanent magnet as can be known: two minor faces of square coil will be subjected to that make progress or downward Ampere force simultaneously.At this moment, effect when motion platform is subjected to fulcrum bar of the spring and recovers elastically-deformable elastic force and above-mentioned Ampere force, when balance between two forces, the height of motion platform reaches stationary value.Therefore the Ampere force difference that different current strength produces feeds suitable electric current to square coil and can obtain the height that needs, utilizes this point to come controlled motion lifting platform height by the size of control input current.
Compare with other same devices, the utility model has the advantages that simple in structurely, show an interesting new approach, utilize the effect of Ampere force to make moving component realize elevating movement, control operation is simple and be convenient to system maintenance.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated: present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed execution mode and concrete operating process, but protection range of the present utility model is not limited to following embodiment.
As shown in Figure 1, present embodiment comprises 3, one fulcrum bar of the spring 7 of 2,5, one square coils of 1,6, two U type magnetic conductors of two block permanent magnets, motion platform 4, pedestal 8.The S utmost point of first permanent magnet 1 and any side inwall of a U type magnetic conductor 2 conductors be fixed together forms a U type permanent magnet, and second permanent magnet 6 and the 2nd U type magnetic conductor 5 also are combined to form the 2nd U type permanent magnet in the same manner; The magnetic line of force of U type permanent magnet is pointed to the opposite side inwall of U type magnetic conductor by the N utmost point of permanent magnet.Two U type permanent magnets are fixed on the two ends, the left and right sides of pedestal 8, have on the U type permanent magnet outside the side direction of permanent magnet;
One end of fulcrum bar of the spring 7 is fixed on the center of pedestal 8, and the other end is fixed on the center of motion platform 4.With fulcrum bar of the spring 7 supporting movement platforms 4.The hardness of fulcrum bar of the spring 7 enough keeps the stable of motion platform 4, makes motion platform 4 have the lifting degree of freedom again.Square coil 3 is fixed on the center of motion platform 4 bottoms, two minor faces of square coil 3 are equidistantly exposed.Adjust the position of square coil 3 and two U type permanent magnets, make U type magnetic conductor 2,5 pass two minor faces of square coil 3 respectively, and make the initial position of square coil 3 be positioned at the center of U type magnet structure short transverse.Two minor faces of square coil 3 equate at interval with distance between the U type magnetic conductor 2,5.Feeding electric current in two square coils can utilize Ampere force that motion platform 4 is moved up and down.
The polarity N of two permanent magnets 1,6 is extremely inside in the present embodiment, and the magnetic line of force of U type permanent magnet is pointed to the opposite side inwall of U type magnetic conductor by the N utmost point of permanent magnet.When square coil 3 feeds the counter clockwise direction electric current, place the left side minor face of the energising square coil 3 in magnetic field to be subjected to Ampere force effect upwards, the right side minor face also is subjected to Ampere force effect upwards, and motion platform 4 is to rising.When square coil 3 fed the clockwise direction electric current, stressing conditions was opposite, and motion platform 4 is to decline.During motion, motion platform 4 is subjected to the restoring force of fulcrum bar of the spring 7 and the effect of Ampere force simultaneously, and when balance between two forces, the hoisting depth of motion platform 4 reaches stable.Therefore the Ampere force difference that different current strength produces feeds certain electric current to square coil 3 and can obtain the height that needs, utilizes this point can come the height of controlled motion platform 4 by the size of control input current.During actual the use, can be according to the needs of Ampere force size in the number that increases U type permanent magnet.
