Embodiment 1

[0056] see Figures 1A-1C , Figure 2A -2C, Figures 3A-3C , Figures 5A-5E As shown, in order to overcome the shortcomings of the existing cable elevators and hydraulic elevators that use linear motors to directly climb the elevator, the double-compartment magnetic levitation elevator driven by the circular arc type linear motor in the preferred first embodiment of the present invention does not use wire ropes to pull the car. Instead, the long stator 4 installed on the left side of the shaft wall of the elevator shaft 1 directly attracts the car 2 to move back and forth. It mainly includes an elevator shaft 1, a car 2, and a motor unit. Wherein: the motor unit is a three-phase linear motor, and the three-phase linear motor is composed of a long stator 4 and a motor winding 3 .

[0057] see Figure 1A , Figure 1B As shown, the long stator 4 is a single column composed of more than half an arc, which is vertically arranged on the left side of the elevator shaft wall. Th...

Embodiment 2

[0064] see picture Figures 4A-4C The double-compartment maglev elevator driven by the circular arc type linear motor of the preferred second embodiment of the present invention shown, the long stator 4 also can be made with the low-carbon garden arc aluminum tube 13 of iron pipe sleeve, is primary motor like this The winding 3 and the long stator 4 repel each other so as not to rub against each other. Other structures and working principles are the same as in Embodiment 1.

[0065] The lifting height of the above-mentioned embodiment is not limited, no matter how high your skyscraper is, as long as you lay the magnetic track vertically, the above-mentioned embodiment will climb up along the long stator 4 all the time. Another feature of the present invention is that two cars can be installed on one stairway, which is conducive to rapid transportation. The present invention is not easy to break down because there is no rotating mechanism, and it is very convenient to manufact...

Abstract

The invention discloses a double-car magnetic suspension lift driven by a circular arc type linear motor. A metal circular arch type upright column long stator serving as the secondary of the motor is arranged in a lift shaft a motor winding serving as the primary is arranged in the long stator; and the motor winding is fixed at one side of the car and is sleeved in the long stator. After being electrified, the motor winding generates a traveling wave magnetic field in an air gap; the secondary is cut by the magnetic field and generates a current in response to an induction; and the current and the magnetic field in the air gap interact with each other to generate an electromagnetic thrust. If the motor secondary is fixed, the motor winding moves linearly under the action of the electromagnetic thrust, and a primary electric engine climbs or descends along a secondary long stator. A pulley is arranged above the lift shaft, two ends of the pulley are connected with two cars by ropes, and a waiting room is arranged in the center of a stairway for the convenience of ascending and descending of the cars and realizing one lift shaft for two cars running. A T type guide way and a pair of brake calipers are arranged on the other side wall of the lift shaft, wherein the brake calipers can prevent the car from falling once the power supply is cut off. The double-car magnetic suspension lift driven by the circular arc type linear motor has the advantages of simple structure, stable operation, low cost and electricity conservation.

Description

technical field [0001] The invention relates to a maglev elevator in the field of elevators, in particular to an elevator that overcomes the height limitation of a wire rope elevator. In particular, a circular arc is formed by using the primary winding of a motor arranged on the left side of the car and a long stator arranged on the elevator shaft wall. The double-carriage maglev elevator driven by the arc-type linear motor, which induces each other to generate electromagnetic thrust, makes the long stator drive the car up and down quickly, and has become a practical and progressive new design, suitable for industrial Widespread application in the world. Background technique [0002] The use of elevators is closely related and inseparable for people. Currently, there are common elevators, which can be mainly divided into the following two types: one is that the elevators are hoisted by steel cables, and the other is hydraulic cylinders Top loaded car. [0003] Although the...
