Abstract
The invention relates to a homopolar-repulsion anti-collision device of an elevator. The traditional elevator commonly has the defects that the safety is low and safety accidents are apt to be caused especially during rush hours. The purpose of the invention is to overcome the defect and to provide a homopolar-repulsion anti-collision device of an elevator. The invention is characterized in that a lower magnet set is installed at the bottom of the wall of an elevator shaft, the N pole of the lower magnet set is upward, an upper magnet set is installed at the bottom of an elevator car and the N pole of the upper magnet set is downward. Since the lower magnetic set is installed at the bottom of the wall of the elevator shaft and the upper magnet set is installed at the bottom of the elevator car, even if the elevator car falls down from air and when the elevator car approaches the ground, the buffer function is obtained, so the emergency safety performance of the elevator is greatly improved.
Description
Technical field:
The invention belongs to the employed a kind of homopolar-repulsion anti-collision device of elevator of elevator industry.
Background technology:
Present elevator ubiquity safety inadequately, particularly at peak load conditions on and off duty, is easy to cause safety misadventure.
Summary of the invention:
Purpose of the present invention just is to overcome above-mentioned shortcoming, and a kind of homopolar-repulsion anti-collision device of elevator that provides.
The present invention is achieved in that what a kind of homopolar-repulsion anti-collision device of elevator was made up of lower magnet group, last group of magnets, lift car and hoistway wall, it is characterized in that: the lower magnet group is installed in the bottom of hoistway wall, the N utmost point of lower magnet group upwards, in the lift car bottom group of magnets is installed, the N of last group of magnets is extremely downward.
The present invention is owing to be equipped with the lower magnet group in the bottom of hoistway wall, in the lift car bottom group of magnets is installed, even so lift car when will land can play the effect of buffering from falling in the air, the safety performance in the time of improving elevator emergency greatly.
Description of drawings:
Accompanying drawing is a work scheme drawing of the present invention.
Each label declaration is as follows among the figure:
1, lower magnet group, 2, go up group of magnets, 3, lift car, 4, hoistway wall.
The specific embodiment:
Now describe embodiments of the invention in conjunction with the accompanying drawings in detail.
For reliable operation of the present invention, lower magnet group 1 and last group of magnets all adopt performance-oriented nonvolatil magnet to install, and its effect is exactly to obtain best buffering effect.
In sum, the present invention is easy to use and reliable, the safety performance in the time of improving elevator emergency greatly.
Claims (1)
