Abstract

The invention belongs to the technical field of energy power, and particularly relates to a novel energy-saving escalator based on a regenerative braking and gravity acting balance principle and a control method. A mode of the novel energy-saving escalator is provided by utilizing a gravity acting counteracting balance principle and the characteristics of a regenerative braking device and a planetary gear, so that the intermittent no-load phenomenon and the influence on escalator equipment existing in a traditional escalator or a traditional energy-saving escalator at present are avoided, andeffective saving of electric energy and recycling of braking energy are achieved.

Description

technical field [0001] The invention belongs to the technical field of energy and power, and specifically relates to a novel energy-saving escalator and a control method based on the principles of regenerative braking and gravity work balance. Background technique [0002] As an important transmission equipment in buildings, escalators have been widely used in public places such as shopping malls, expo centers, railway stations, subway stations, and underground passages. According to incomplete statistics, the current use of escalators in my country exceeds 60,000 units, and is increasing at a rate of more than 10% year by year. Among them, non-energy-saving escalators accounted for more than 95%. If the power of one escalator is 5.5kW and it runs for 12 hours a day, each escalator will consume 24,090kW·h of electricity per year. The escalator alone in the country consumes about 1.3×109kW·h of electricity each year, and each escalator will have intermittent no-load phenome...
