Specific embodiment
In order to be best understood from the purpose of the present invention, structure and function, with reference to the accompanying drawing, to magnetic suspension electricity of the invention
Terraced system does further detailed description.
As shown in Figs. 1-2, the elevator that magnetic levitation elevator system of the invention includes elevator and is arranged in inside elevator
Carriage is provided with the permanent magnet 10 as electric mover on lift car, and it is fixed as motor to be provided in elevator sidewall 50
The linear motor winding 20 of son, after energization, permanent magnet 10 and linear synchronous generator winding interact, to mention for lift car
For static suspension power and propulsive force, thus realize that lift car moves up and down in elevator by linear electric machine traction,
And the hovering of lift car different floors in elevator is realized by the stall function of linear motor.
As shown in figure 3, be used as motor stator linear motor winding 20 be preferably strip stator linear synchronous motor around
Group 20, i.e. linear motor winding 20 is elongated, and it is vertically extending be arranged in elevator sidewall 50, thus and permanent magnetic
10 electric mover of body forms strip stator linear synchronous motor.
As shown in figure 4, above-mentioned permanent magnet 10 is Halbach (Halbach) array permanent magnet 10, Halbach
(Halbach) array permanent magnet 10 has excellent poly- magnetic characteristic.Select Halbach (Halbach) linear type permanent magnet
10 arrays can the problems such as very good solution equipment cost, structure be simple, reliability, safety, electromagnetic pollution, therefore electric mover is not
Preferably select high/low temperature superconducting magnet.The structure of Halbach (Halbach) array permanent magnet 10 is as shown in figure 4, arrow in figure
Shown direction is magnetizing direction or the magnetic circuit direction of permanent magnet 10, and section shown in dotted line frame is Halbach in Fig. 4
(Halbach) the minimum repetitive unit of array.
Halbach (Halbach) array permanent magnet 10 is installed on to the two sides of lift car as a result, and in elevator
Linear synchronous generator winding is installed, the two combination provides static suspension power and propulsive force on the corresponding two sidewalls of well.
It is additionally provided with T-rail 30 on lift car, has been correspondingly formed guiding groove 40, guiding groove on the side wall 50 of elevator
Guiding magnet is provided in 40, the T-rail 30 on lift car protrudes into guiding groove 40, and the guiding magnet in guiding groove 40 can
Electromagnetic force is generated to T-rail 30, to guide lift car lifting by T-rail 30.
As shown in figure 5, the guiding magnet being arranged in guiding groove 40 is electromagnet and permanent magnet hybrid magnet, guiding magnet packet
Including iron core 41 and the permanent magnet 42 being arranged in iron core 41 and the electromagnetic coil 43 being arranged on iron core 41, guiding magnet includes
The multiple iron cores 41 being oppositely arranged, multiple iron cores are oppositely arranged and wherein or inside limits guiding groove 40, opposite on iron core
Permanent magnet 42 and electromagnetic coil 43 the composition multiple groups of setting are oriented to magnetic group, and guiding magnetic group can be by T-rail 30 to lift car
Magneticaction is generated, so that lift car to be kept to the suspended state not contacted with guiding groove 40 and elevator sidewall 50, or is embraced
Death situation state.
For example, in normal operating conditions, iron core A1, iron core C1 and iron core A2, iron core C2 match use respectively, pass through difference
Sub-control system realizes the guide function of horizontal front-rear direction (up and down direction shown in fig. 5).Iron core B1, iron core B2 pairing use, and lead to
Cross the guide function that horizontal left and right directions is realized in difference control.In case of a fault (when electromagnetic coil cannot effectively be powered), with
For a left side is half side in Fig. 5, the phenomenon that iron core A1, iron core B1 or iron core B1, iron core C1 suction dead track namely iron core will occur
A1, iron core B1 or iron core B1, iron core C1 inhale the T-rail 30 on dead lift car, can so guarantee extreme fault condition
Under, by power-off so that guiding magnet inhales dead T-rail 30, so as to avoid the occurrence of personnel and property loss.
Thus, on the one hand, under normal circumstances, electromagnet and permanent magnet hybrid magnet play guiding and adjustment car position or appearance
State function avoids running process of elevator carriage from rubbing with track, on the other hand, the electromagnetism in electromagnet and permanent magnet hybrid magnet
In the cold situation of body, the T-rail 30 in hybrid magnet and guiding groove 40, which is in, inhales death situation state, it is ensured that under fault condition
Carriage and guiding groove 40 extremely can guarantee safety by embracing rail suction.Utilize the hybrid electromagnetic body with permanent magnet 10 and T-type guide rail
Guiding and defencive function are realized in interaction between interior T-rail 30.
Above-mentioned T-type guide rail selects ferromagnetic type material, such as A3 steel or railway track material, and will table corresponding with guiding magnet
Face carries out mantle friction processing, to improve the coefficient of friction on guiding magnet surface.On the one hand, T-rail 30 and guiding magnet
Iron core forms closed magnetic circuit, realizes that normal guide function, another aspect T-rail 30 provide enough stiffness and strength, really
It protects T-rail 30 and guiding groove 40 and inhales the structural strength in dead situation and be enough to support hovering shape between lift car and elevator
State.
It is appreciated that the present invention is described by some embodiments, and what those skilled in the art knew, it is not taking off
In the case where from the spirit and scope of the present invention, various changes or equivalence replacement can be carried out to these features and embodiment.Separately
Outside, under the teachings of the present invention, can modify to these features and embodiment with adapt to particular situation and material without
