高楼逃生装置结构设计 摘要：本文介绍的是一种高楼逃生装置。前期进行了市场调研，发现市面上的高楼逃生装置均存在成本高，操作复杂，安全系数低等缺陷。正对于此，我们设计了该装置。该设计逃生装置根据机械设计，机械原理创新理论，设计出一种负反馈闭环系统的低成本，高安全性的高楼逃生装置。该装置具有低成本、安全系数高、操作简单、纯机械并且无电气结构等特点，最后通过对逃生装置机构零部件进行计算，画出整个机构的CAD图形，在多次计算和试验之后，确定了不论是任何人在高楼遇险时都能从高楼平安逃生，达到了本次机械设计的目的。 关键词高楼火灾逃生器；机械结构设计；闭环系统；往复；可控。 Structure Desig
