摘要
提出了两种基于摩擦的纯机械高楼自助缓降逃生装置,该装置不需要外在动力,可多人次循环使用;其基本原理是利用偏心钟摆\杠杆增力结构使逃生者自重转化为相应的摩擦阻力。逃生者体重越重,该装置产生的摩擦阻尼越大,从而使不同体重的人都能以近似相同的安全速度缓降逃生。该装置结构紧凑、简单,并通过机械结构和力学方面的分析计算和高楼缓降试验,证明其安全可靠。
This paper introduces two kinds of tower escape apparatus.The apparatus has no use of other power and it can be circularly used for many people.The major character of the device is that it can transform the load into the corresponding friction through the pendulum and lever framework, so the people whith different avoirdupois can ground safely,and this character has been verified by calculating and testing.
