关于双螺旋形自动扶梯的概念设计

在对三菱电机公司的螺旋形自动扶梯分析的基础上，指出了人们对螺旋形自动扶梯的功能和结构的认识误区；建议以新的空间观念、结构理念和机械手段来解决现有的螺旋形自动扶梯的设计和制造的理想度，基于Triz理论分析并提出了螺旋形自动扶梯的功能核心和技术难点。同时指出现有设计理念中螺旋形自动扶梯各个系统之间的问题，如空间结构、动力学模型、机构设置等，都是源于人们一直固守的链式传动机制。

Concept Design of the Double-spiral Escalator

According to the analysis of the spiral escalator made by Mitsubishi Electric Corporation, this paper points out the misunderstanding to the function and the construction of the spiral escalator and the current design concept for the spiral escalator such as its space construction, dynamic model and mechanism setting etc. originating from the chain transmission theory, and puts forward the core function and the technical difficulties of the spiral escalator design based on Triz theoretical analysis. It also suggests how to get the ideal of the spiral escalator design and the manufacture with the new space idea, the new structure concept and the new mechanical means.
