| With more and more people to live and work in buildings,buildings for dangerous situations(such as fire)and other emergency escape device is also increasing,but the current building escape device presents a series of drawbacks: it is difficult to achieve more at the same time to escape,relying on the external driving force,the economy,the need of professional training to the poor control,cannot achieve the purpose of escape.According to the characteristics of the high-rise building escape,we can design a kind of escape device which can realize the control of the descent speed by using the weight of the human body,and can effectively control the descent speed.At home and abroad about the uninterrupted high-rise escape device research and application to achieve more than less,the uninterrupted escape as the goal,mainly carried out a series of research work,and the device powertrain parts,mechanism optimization design and verification.Through the calculation,it can be seen that the device can realize the function of uniform speed,which can make the escape personnel arrive at the ground at a safe speed,and achieve the goal of escape smoothly. |
