毕业设计论文高楼火灾逃生器设计DesignofEscapeMachinefromHighriseforFire学生姓名学院名称专业名称指导教师20年5月27日徐州工程学院毕业设计论文I摘要本文从开始介绍了高楼逃生装置的背景和研究意义,并对现有的一些高楼逃生装置进行了分析和对比,发现大多数的装置有成本高、机构复杂、安全系数低等一些不足之处。本设计根据机械创新理论,设计出一种基于负反馈闭环系统的高楼逃生装置,该装置具有成本低、操作简单、安全系数高、纯机械无电气结构等优点,最后通过对设计机构的零部件进行计算,得出整个机构的图形,在多次试验和计算之后,确定了不论是小孩还是老人都能从高楼平安降落到地面,达到了本次设计的目的。关键词高楼火灾逃生器机械创新理论往复可控AbstractFirstly,thispaperdescribesthebackgroundandsignificanceoftallbuildingescape徐州工程学院毕业设计论文IIdevice.Andsomeoftheexistingtallbuildingescapedevicesareanalyzedandcompared,mostofthedevicesarecostly,complexorganization,thesafetyfactorandlownumberofshortcomingsarefound.Thedesignappliedtheoryofinventiveproblemsolving.Todesignanegativefeedbackloopsystembasedontallbuildingescapedevice.Thedevicehasmanyadvantagessuchaslowcost,simpleoperation,highsafetyfactor,purelymechanicalnoelectricalstructure.Finally,thecomponentsofthecalculateddesignagency.Thegraphicsgetinthewholebody,aftermanytestsandanalysis,determiningwhetherchildrenortheelderlycansafelydescendtothegroundfromhighbuildings.thepurposeofthisdesignhasachieved.KeywordsHigeriseescapemachineforfireMachineryinnovationtheoryReciprocatingControllable徐州工程学院毕业设计论文III目录摘要..................................................................................................................................................IAbstract...........................................................................................................................................I1绪论.............................................................................................................................................11.1设计背景及意义...................................................................................................................11.2国内外研究概况..................................................................................................................21.3高楼火灾逃生器的实例......................................................................................................31.3.1内凸轮式高楼火灾逃生器.............................................................................................31.3.2涡轮蜗杆式高楼火灾逃生器.......................................................................................41.3.3钢丝绳防滑逃生装置...................................................................................................41.3.4心摩擦式高楼火灾安全逃生器...................................................................................52整体方案设计.............................................................................................................................62.1方案构设..............................................................................................................................62.1.1方案一...........................................................................................................................62.1.2方案二...........................................................................................................................92.1.3方案三..........................................................................................................................112.2方案的比较与选择............................................................................................................123装置零部件设计.......................................................................................................................133.1轴的设计............................................................................................................................133.1.1轴的概述.....................................................................................................................133.1.2主动轴的设计.............................................................................................................143.1.3从动轴的设计.............................................................................................................153.2齿轮的设计........................................................................................................................163.2.1齿轮的概述.................................................................................................................163.2.2齿面接触疲劳强度和齿根弯曲强度设计.................................................................163.3棘轮的设计........................................................................................................................203.3.1棘轮的概述.................................................................................................................203.3.2棘轮的设计.................................................................................................................213.4其他零部件的设计选择....................................................................................................223.4.1标准件的选择.............................................................................................................223.4.2安全座椅的选择.........................................................................................................233.4.3挂钩的设计........................................................................................................
