Embodiment Construction

[0033] refer to Figure 1 to Figure 5A guide device 10 according to a first embodiment of the present invention will be described. Guiding device 10 such as figure 1 The car 4 shown is installed in the elevator 1. A pair of ferromagnetic iron guide rails 2 are provided on both sides of the elevator 1 as viewed from the side of the entrance 41 of the car 4 . The guide device 10 is provided at a total of four places at both ends of the upper beam 421 and the lower beam 422 of the car frame 42 of the car 4 corresponding to the guide rail 2 . The car 4 is suspended on the main cable 3 wound on the hoist. Each guide device 10 generates a magnetic force between the blades 21 of the guide rail 2 to hold the car in a non-contact manner. Driven by the hoist, the car 4 moves along the guide rails in the lifting passage 6 .

[0034] For illustration, take figure 1 The central part of the bottom surface 43 of the shown car 4 is used as a reference, and the right direction viewed fro...

Abstract

A guide apparatus includes a pair of guide rails (2), magnet units (11), pedestals (12), a sensor unit (13), a magnetic guide control apparatus as a control unit (14), and projected parts (181, 182). The magnet unit (11) includes electromagnets (113A, 113B, 114A, 114B) and permanent magnets (111, 112) and magnetic poles (11C, 11S1, 11S2) thereof are opposed to a blade (21) of the guide rail (2) from three directions with a gap. The projected parts (181, 182) are formed with side parts of a tip part of a central magnetic pole (11C) opposite to a tip surface (21a) of the blade (21) of the guide rail (2) among the magnetic poles of the magnet unit (11) being brought closer to the guide rail than a center section thereof.

Description

technical field [0001] The present invention relates to a guide device for holding a guide rail by magnetic force provided in the car for guiding the elevator car along the guide rail. Background technique [0002] The elevator lifts the car in the hoistway through the main cable hung on the hoist, and moves the car by driving the hoist. In order to move along the guide rails laid vertically in the hoistway, the car has a guide device. According to the position and weight of passengers or goods, the car is subjected to a force in a direction crossing the direction of movement during movement. In order to support such forces, the guiding device needs to hold the car with sufficient force. [0003] The guiding device is divided into a contact guiding device and a non-contact magnetic guiding device. Contact guides have rollers or wheel shoes that make contact with the rail. Magnetic guides maintain a gap relative to the guide rail by magnetic force to maintain non-contact....
