直线电动机直驱多轿厢循环电梯研究及设计进展

Progress on research and design of multi-car cycling elevator directly driven by linear motor

传统电梯单纯依靠提升速度、采用双层轿厢以及单井道双轿厢技术不能从根本上提高其单位时间内的运输能力。直线电动机直驱多轿厢循环电梯轿厢可在单井道内或在井道间循环运行,轿厢运行速度远超现有电梯驱动技术的限制,且投入运行的轿厢数量可根据客流量及候梯时间柔性实时调整,为克服现有曳引、链条或液压传动技术的电梯在运输效率、候梯时间、运量、提升高度等方面的固有缺陷提供了实现的可能。合理的系统设计能实现类似地面交通运输系统的可立体变轨的多轿厢循环提升系统,使其成为全方位可实时调整的立体交通运输体系的有机组成部分。

It was impossible to fundamentally improve the specific transport capacity of the tradition elevator only by promoting its running speed, applying double-layer car and double cars in single shaft. The cars of the multicar cycling elevator directly driven by the linear motor ran in single shaft or circularly ran among shafts, thus the running speed greatly exceeded the one limited by present elevator drive technology, and the number of the cars put into use could be real-time adjusted according to passenger traffic and waiting duration. Therefore, it was possible for the present elevator applying traction, chain or hydraulic drive technology to overcome the inherent insufficiency about transport efficiency, waiting duration, transport capacity and lifting height. Reasonable design could realize the stereo orbital-transfer multi-car cycling hoist system similar to the ground transport system, thus it could become a part of the whole real-time controlled stereo traffic transport system.
