Embodiment Construction

[0038] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0039] see Figure 1 to Figure 3 , which is a schematic structural diagram of the magnetic guide shoe device provided in this example.

[0040] It can be seen from the figure that the magnetic guide shoe device 1 mainly includes a support frame 2 and a magnetic main body unit 3 disposed in the support frame 2 .

[0041] The magnetic body unit 3 is mainly composed of corresponding permanent magnets, electromagnets (consisting of corresponding winding coils and iron cores) and iron cores. ) 18a, 18b, and 18c all maintain a certain gap in three directions. By controlling the magnetic force of the magnetic guide shoe device 1 , the passenger car can be floated from the guide rail 17 without contact and do a suspended lifting movement along the gui...

Abstract

The invention discloses a magnet unit and a magnetic guide shoe device. The magnetic guide shoe device mainly comprises a magnetic body unit (3), a base (19), a side plate (14a), a side plate (14b) and a cover plate (15). The magnetic body unit (3) is composed of electromagnets (namely, winding coils) and permanent magnets, and then certain gaps are kept between the magnetic guide shoe device and a cutting edge (18a), a cutting edge (18b) and a cutting edge (18c) of a guide rail (17) in three directions. The base (19) is used for supporting and fixing the whole magnetic guide shoe device. The magnetic guide shoe device achieves lossless control, and is easy to assemble, good in stability and capable of achieving miniaturization.

Description

technical field [0001] The invention relates to elevator technology, in particular to the non-contact guidance technology for passenger cars in elevators. Background technique [0002] In general, the passenger car of an elevator is supported by a pair of guide rails arranged vertically in the hoistway, and travels through the cables of the traction machine. At this time, the guide rail suppresses the shaking of the passenger car due to unbalanced load and movement of passengers. [0003] Here, as a guide device for a passenger car of an elevator, a roller guide rail composed of a wheel contacting the guide rail and a hanger, or a guide shoe slidably guided relative to the guide rail, or the like is used. However, in such a contact-type guide device, vibration and noise are generated due to warping or seams of the guide rail, and noise is also generated when the roller guide rail rotates. Therefore, there is a problem that the comfort of the elevator is impaired. [0004]...
