Title:
UP-DOWN INTEGRATED ESCALATOR THAT CONSERVES ENERGY BY MEANS OF GRAVITY
Document Type and Number:
WIPO Patent Application WO/2012/055377
Kind Code:
A1
Abstract:
An up-down integrated escalator that conserves energy by means of gravity for transporting people up and down floors. Said escalator utilizes the weight of the people moving downward to directly offset the weight of the people moving upward, and comprises an up slope (130) and a down slope (140), linked together, formed by a frame (100), combination guide tracks (200), a step belt (300), and determination and control devices (410, 420, 430). The determination and control devices (410, 420, 430) of said escalator checks the people moving upward and the people moving downward, calculates, and makes determinations, so that a drive device can ensure the normal operation of said escalator using the minimum power output. The present invention solves the problem of the existing escalators being able to operate only uni-directionaly, upward or downward, and being unable to directly utilize energy generated from the weight of people moving downward.
