一种新型防坠落安全装置设计与实现

A Study on the Design and Implementation of a New Fall Arrest Safety Device

针对附着式升降脚手架市场上使用的防坠落安全装置结构复杂笨重,架体易上升难下降等缺点,设计一种结构简单、使用可靠且维护方便的纯机械制动防坠落安全装置,重点介绍了该装置的防坠落原理及关键零件的强度校核分析,最后给出防坠落试验检测结果。

The new- style fall arrest safety device with purely mechanical braking was invented to improve the complicated and heavy one, which aiming at the attached self- lifting scaffolds and its easy to rise but diffi- cult to fall. The new device is simple in structure, reliable in use and convenient in maintenance. The principle of fall arrest and strength check analysis of the key parts were introduced emphatically, furthermore, the test re- sult of fall arrest was offered in the end.
