Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing.

[0022] A hybrid excitation non-contact suspension guidance system, such as figure 1 , 2 As shown, it includes a guide rail 4 and a guide assembly 40, the guide rail 4 is a strip structure with a rectangular cross section, and the guide rail 4 is vertically fixed on the hoistway wall. The guide assembly 40 includes a left yoke 1 , a right yoke 2 , a permanent magnet 3 , a left coil winding 5 , a right coil winding 6 , a left tooth 7 and a right tooth 8 . The left yoke 1 is a C-shaped trough with parallel horizontal upper arms and lower arms. The right yoke 2 is a C-shaped trough with the same structure as the left yoke 1. The notches of the two are opposite to each other. Symmetrically arranged on both sides of the guide rail 4 to form a semi-encircling structure, the structures on the left and right sides are completely symmetrical. A guide rail 4 is arranged between the...

Abstract

The invention discloses a mixed-excitation non-contact levitation and guidance system which adopts permanent magnet and electromagnet mixed excitation, can be used for remarkably reducing the control current, is low in power consumption and can be used for non-contact guidance of a hoisting machine and an elevator. The mixed-excitation non-contact levitation and guidance system comprises a guide rail and a guide assembly, wherein the guide assembly is composed of a left yoke, a right yoke, a permanent magnet, a left coil winding, a right coil winding, a left gear and a right gear; the left yoke and the right yoke are both of C-shaped groove bodies, notches of the left yoke and the right yoke are opposite and are symmetrically formed in the left and right sides of the guide rail to form a semi-surrounding structure and form air gaps in two sides; two lower arms of the left yoke and the right yoke are connected into one body by the permanent magnet, the lower arms of the left yoke and the right yoke are symmetrically provided with a folded-line-shaped left gear and a folded-line-shaped right gear in a vertically upward direction, and are provided with coil windings correspondingly in a sheathing manner, the top end surfaces of the left gear and the right gear are parallel to the side surface of the guide rail and are provided with gear air gaps. The mixed-excitation non-contact levitation and guidance system is small in part quantity, small in occupying space and low in power consumption and can be controlled simply.

Description

technical field [0001] The invention belongs to the fields of electrician and elevator, in particular to an electromagnetic guidance system, in particular to a hybrid excitation non-contact suspension guidance system. Background technique [0002] With the development of social economy, people are building more and more high-rise and super high-rise buildings. For example, the Burj Khalifa in the United Arab Emirates is 828 meters high and has 162 floors; the Mecca Royal Clock Tower Hotel in the Kingdom of Saudi Arabia is 601 meters high. , a total of 95 floors; the Shanghai Tower is 632 meters high, with a total of 125 floors; Taipei 101 Financial Center is 509 meters high, with a total of 106 floors; the Petronas Twin Towers in the capital of Malaysia is 457 meters high, with a total of 88 floors. Several other skyscrapers are currently in the planning and construction stages. With the continuous increase of floor height, it is necessary to configure high-speed elevators....
