为了更好地在高层建筑火灾中逃生,研发了一种包角加行星轮式高楼自适应逃生器,主要采用包角轮缠绕钢丝绳的方法,把直线下降运动转化为包角轮的旋转运动,旋转离心力通过行星轮系减速转换成摩擦轮的离心力,摩擦轮外带有自适应离心块,自适应离心块在离心力的作用下旋转和金属外壳摩擦,到达逃生的目的。建立了该逃生器的运动学和力学方程,采用Matlab软件对其进行优化分析,得出了运动曲线图。该逃生器经测试适用于各种高层建筑,采用全金属制作很好地保证几十年的存放期,具有高效、快捷、耐火、小巧方便的特点,能够取得良好的使用效果。
In order to better escape in the high-rise building fire, a kind of angle-plus-planet-type high-rise self-adaptive escapement was developed. The main method is the wrapping of the wire rope by the angle wheel to convert the straight- Rotating centrifugal force is converted into centrifugal force of the friction wheel through the planetary gear train decelerating. The friction wheel is equipped with an adaptive centrifugal block, and the self-adaptive centrifugal block is rotated by the centrifugal force and rubs with the metal shell to reach the purpose of escape. The kinematics and mechanics equations of this generator are established, and its optimization is analyzed by Matlab software. The motion curve is obtained. The utility model has been tested and applied to various high-rise buildings. The utility model has the advantages of high efficiency, fastness, fire resistance, compactness and convenience, and good use effect.
