摘要
针对高层建筑火灾外部救援设备存在的作业高度不足、救援效率低的问题,对高层建筑火灾分布特点及救援难点进行分析,提出了一种新型高层建筑火灾外部救援系统。利用TRIZ理论建立救援系统,采用抛挂装置的因果轴分析图,确定了抛挂装置中存在的不足之处;采用“矛盾解决原理”分析和解决了系统中涉及的技术矛盾,借助“物-场模型”对绳索收放器进行了优化设计,提高了抛挂装置的安全性;最后结合ANSYS/Workbench有限元分析软件对抛挂装置中挂钩的应力与变形进行了分析验证,并提出了进一步的优化方案。研究结果表明:对抛挂装置优化设计后的系统具有快速展开救援、环境适应性强、操作简单等特点,抛挂装置的结构刚度高、设计更加合理,可为救援系统后续相关研究提供参考依据。
Aiming at the problems of insufficient working height and low rescue efficiency of external rescue equipment in high-rise building fire,the fire distribution characteristics and rescue difficulties of high-rise building were analyzed,a new type of external rescue system in high-rise building fire was put forward.The cause and effect axis analysis diagram of the throwing device used in the rescue system were established by using TRIZ theory,and the shortcomings of the throwing device were determined.The technical contradictions involved in the system were analyzed and solved by the“principle of contradiction solution”,the design of the rope retractor was optimized with the aid of the“object field model”,which improved the safety of the throwing device.Finally,the stress and deformation of the hook in the throwing device were analyzed and verified with the help of ANSYS/workbench finite element analysis software,and the further optimization scheme was put forward.The results show that the optimized system has the characteristics of rapid rescue,strong environmental adaptability,simple operation and so on.The structure rigidity of the throwing device is high and the design is more reasonable,which provides a reference for the follow-up research of the rescue system.
