Abstract
The invention leads the elevator car to suspend in the magnetic field by using the principle that homopolarities of the permanent magnetic field repulse. The elevator car runs through the driving of the flexible magnetic guide-way. An extraction way replaces a traction way for providing power, thus the running efficiency and safety of the elevator can be improved.
Description
Technical field:
The invention belongs to the elevator of a kind of later-model highly effective and safe in the transportation means.
Background technology:
At present, traditional elevator is to utilize the wirerope traction to reach the purpose of lifting, and efficient and safety are along with popularizing with constantly increasing of skyscraper reduced, and be then ineffective fully when unexpected situation takes place.
Summary of the invention:
In order to solve the deficiency of traditional traction elevator in efficient and safety, change the operational mode of elevator, mode with extruding flexible magnetism guide rail is replaced the wirerope mode of traction, can allow the lift car that has homopolarity permanent magnet wall be suspended on the flexible magnetism guide rail like this, extruding flexible magnetism guide rail reaches and drives the purpose that elevator moves up and down.The cross section is that the groove of zigzag flexible magnetism rail back is corresponding with the tongue of hoistway wall, and the permanent magnet wall of lift car is fitted more closely because of the principle compressing flexible magnetism guide rail and the hoistway wall of homopolar-repulsion, the traction that has replaced cable with the interlock and the friction force of hoistway wall with this flexible magnetism guide rail, guaranteed the safety of elevator, also expanded the space for increasing the elevator operating efficiency.
Development along with modern architecture, the height of building is in continuous increase, elevator becomes requisite means of delivery, although present elevator is improving constantly rising or falling speed, but compare the needs that still can not satisfy reality with the continuous growth of building height and carrying capacity, can only be remedied by increasing elevator quantity, wasted the space.The actuating device of magnetic levitation elevator is in lift car, the traction that has broken away from wirerope, also just needn't take all hoistway space, and be the friction force of self and hoistway wall to its flexible magnetism guide rail that produces pulling force because of utilization, sphere of action is to get seldom one section in the lift car top/bottom latitude, do not influence other lift car that moves on the flexible magnetism guide rail of other section, thereby can in same elevator, move the multi-section elevator simultaneously, improve delivery efficient and carrying capacity.
Skyscraper is when meeting accident, and traditional elevator can only be out of service, makes and but can not use when needing most carriage lift, and this is the defective that its type of drive causes.The magnetic levitation elevator that employing flexible magnetism guide rail mode drives relies on the gravity of elevator self to cooperate manual control to move voluntarily downwards under the situation of no external power, relies on backup power to cooperate manual control also can upwards move.Under the situation of flexible magnetism guide rail fracture, drive because of it just relies on partially flexible magnetic conductance rail, so can be in fracture place of flexible magnetism guide rail continue safe operation up and down respectively.

Fig. 1 is single portion operation magnetic levitation elevator front perspective view
Fig. 2 is single portion operation magnetic levitation elevator side perspective view
Fig. 3 is multi-section operation magnetic levitation elevator front perspective view
Fig. 4 is multi-section operation magnetic levitation elevator side perspective view
The specific embodiment:
Fig. 1 Fig. 2 is the magnetic levitation elevator front and the side perspective view of single portion operation, is applied to the low-rise building elevator.The flexible magnetism guide rail is divided into the N utmost point and the S utmost point is fitted by the groove at the back side and the tongue of hoistway wall.The cross section of lift car is a bullet shaped, it is relative with magnetic pole with the flexible magnetism guide rail with the S utmost point that the permanent magnet car walls is divided into the N utmost point, by the restriction of driven wheel to the flexible magnetism guide rail, because of the magnet homopolar-repulsion is suspended on the flexible magnetism guide rail, the flexible magnetism guide rail is exerted pressure makes it more to fit tightly on hoistway wall simultaneously.By the extruding of driven wheel, drive lift car and move up and down the flexible magnetism guide rail.When manually control is used for elevator and can't moves automatically by operation of handle manual control elevator or braking.Equipment is used power supply in the lift car bottom, is used for providing when no external power source interim power supply.The protection elevator can out of controlly not drop when urgent protection gear was used for driven wheel fracture or inefficacy.Emergency protective device is used for providing urgent protection when elevator tenesmus out of control.When fracture takes place the flexible magnetism guide rail,, utilize the friction force of flexible magnetism guide rail and hoistway wall that lift car can out of controlly not dropped, and can continue operation in the top or the bottom of breaking-down point because lift car extruding flexible magnetism guide rail makes it to fit with hoistway wall.Stop because of load-carrying changes when location lock is used for elevator and stops to open the door up and down and be moved.Guide wheel is used for stablizing elevator with guide rail and external power supply, communication line and the circuit of other control monitoring system are connected.
Fig. 3 Fig. 4 is applied to high level and high-rise building elevator for the magnetic levitation elevator front and the side perspective view of multi-section operation.The magnetic levitation elevator of basic and single portion operation is identical, installs track additional and replys wheel, is used to make the track homing, is beneficial to other lift car application and moves.Elevator control monitoring and dispatching system relative complex guarantee the normal each other operation of each elevator, and can not influence each other even collide.
