Problems solved by technology

[0005] The present invention aims at the problem of vibration and noise generated by the existing common contact guide device, as well as the problem of mutual interference and large loss in the control of each direction of the "E" type magnetic levitation guide shoe, and provides a new type of elevator magnetic levitation guide device
The guiding device adjusts the magnetic force of the permanent magnet and the electromagnet against the guide rail, so that the elevator car does not touch the guide rail, so as to achieve the effect that the elevator runs up and down smoothly along the guide rail, and effectively solves the problems existing in the existing guiding device.

Embodiment Construction

[0032] 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.

[0033] see figure 1 , The elevator magnetic levitation guide device 100 provided by the present invention mainly includes five parts: a base 101 , an auxiliary guide wheel 102 , a magnet unit cover 103 , a magnet unit 104 and a distance sensor 105 .

[0034] Wherein, the base 101 is a frame structure made of metal material, which is used to fix the whole guide device 100 on the elevator car 200 (such as image 3 shown), and is used for installing the auxiliary guide wheel 102 and connecting the magnet unit cover 103; at the same time, the base 101 is provided with a placement groove 101a, which is used for fitting the elevator guide rail 300 during installation.

[0035] For elevator guide rail 300, such as Figure 4 As shown, specifically, a ...

Abstract

The invention discloses a magnetic levitation guide device of an elevator, which is embedded into guide rails, and a permanent magnetic field and an electromagnetic field are generated between the magnetic levitation guide device and the guide rails to allow a car to be levitated on the guide rails. The car is levitated on the guide rails by adjusting the permanent magnetic field and the electromagnetic field between the guide rails and the guide device, so that the roots of rock and friction noise of the elevator are eliminated, true undamaged control is achieved, the control difficulty is reduced, the taking comfort of the elevator is improved greatly, and in addition, the utilization ratio of a permanent magnet is increased due to adjustable design of the permanent magnet.

Description

technical field [0001] The invention relates to an elevator car technology, in particular to an elevator car or a maglev guiding device for reuse. Background technique [0002] The currently widely used elevator car runs up and down along the guide rails installed vertically in the hoistway. For other reasons, the car tilts forward and backward or left and right with the suspension point as the center of rotation. Generally, a set of guide devices are equipped at both ends of the upper and lower beams of the car, usually guide shoes or rolling guide wheels are embedded on the surface of the guide rail, which play a guiding role for the upper and lower running of the car and rely on its support with the guide rail. Force to maintain the balance of the car. [0003] Due to the unbalance of the car, the guide shoe or rolling guide wheel usually used as the guide device is in contact with the guide rail surface in one or several directions. When the car runs up and down, the s...
