面向高层楼房的个人逃生装置对于危难中挽救人员生命极其重要。针对城市高层楼房缺少简易便携的个人逃生装置的问题,文章设计了一种便捷可靠的脚踏式索降逃生装置。根据高层个人逃生装置的功能需求,提出了新型索降器的总体设计构想,阐释了基于旋转运动控制滑降制动的索降器油压系统制动原理和螺旋进止结构的设计原理。
Personal escape devices for high-rise buildings are vital to saving lives in distress. In view of the lack of a simple and portable personal escape device in urban high-rise buildings, a convenient and reliable foot-drop escape device is designed. According to the functional requirements of high-level personal escape device, the overall design concept of the new type of cable lifter is put forward. The brake principle of the hydraulic system of the cable lifter based on the rotary motion control and the design principle of the screw in-and-out structure are explained.
