摘要: 绳索救援中提升系统实际增益小于其理论增益,导致在救援提升作业时不能进行精准操作。通过实验,测试多种型号和类型滑轮的效率;测试抓绳器(PCD)对提升系统效率的影响;测试安全钩、I'D系列下降器代替滑轮使用时的效率。利用“T”型分析法,代入实测滑轮效率,计算提升系统实际增益。为绳索救援提供理论依据,避免作业的盲目性,提高救援效率。

关键词: 消防, 绳索救援, 提升系统, 效率测试, “T”型分析法

Abstract: In rope rescue, the actual mechanical advantage of hauling system is less than the theoretical mechanical advantage, resulting in an overestimation of the rescue capability. Experiments are designed to test the efficiency of various types of pulleys, the effect of progress capture device (PCD) on pulley efficiency, and the efficiency of carabiner and I'D instead of pulley. Through the T-Method ,calculated mechanical advantage of the hauling system by substituting the test result of pulley efficiency. To provide data support for accurately evaluating the actual mechanical advantage of hauling system in rope rescue,and improving rescue effciency.

Key words: fire fighting, rope rescue, hauling system; effciency test; T-method
