1.5吨型手拉起重葫芦设计摘要起重机械是减轻笨重体力劳动，提高作业效率、实现安全生产的起重运输设备。在国民经济各部门的物资生产和物资流通中，手拉葫芦作为关键的工艺设备或重要的辅助机械，应用十分广泛。一个完整的作业循环一般包括取物、起升、平移、卸载，然后返回原处等环节。经常起动、制动、正向和反向运动是起重机械手拉葫芦的基本特点。手拉葫芦的设计和使用应符合GB3811《起重机设计规范》和GB6067《起重机安全规程》的规定。此次设计的手拉葫芦是吊装起重物在1.5吨左右，运用一整套II级齿轮减速传动，手拉葫芦主要用在工厂、矿山、建筑工地、码头、船坞、仓库或者在没电的情况下施工的场合，原动力靠人工是手拉力来传动，减小手拉力，增大齿轮啮合传动比，使结构紧凑美观，经济耐用是设计的目的。手拉葫芦是通过拽动手动链条、手链轮转动，将摩擦片棘轮、制动器座压成一体共同旋转，五齿长轴便转动片齿轮、齿短轴和花键孔齿轮带动起重链轮，由起重链轮带动起重链条吊起重物。起重机械，手拉葫芦，起动，制动，齿轮减速传动关键字：I平顶山工业职业技术学院毕业设计说明书（论文）ABSTRACTThehoistingmachineryisrelieveheavymanuallabor,improveworkingefficiency,realizesafeproductionofliftingtransportationequipment.Innationaleconomicsectorsofmaterialproductionandmaterialcirculation,handhoistaskeytechnologicalequipmentorimportantauxiliarymachinery,applicationofveryextensive.Acompletehomeworkcirculationgenerallyincludestakethings,hoisting,translation,unloading,andthenreturnstoitsplacesuchlinks.Oftenstarting,braking,forwardandreversemovementisliftingtypehoiststhebasiccharacteristicsofmanipulator.HandtypehoistsshouldcomplywiththedesignanduseofGB3811thecranedesigncodeandGB6067thecranesafetyrulesregulation.Thedesignofthehandinthegourdisliftinguparoundtheclog1.5tons,usingasetlevelIIgeartransmission,andhandgourdbasicallyuseinfactories,mines,constructionsites,dock,dock,warehouseordon'thaveelectricitysituationinconstructionoccasions,impulsionbyartificiallyisahandpulltodrive,minussmalltension,gearingratioincreases,compactstructureandbeautiful,economicdurableisthedesignpurpose.Thehandtractivebottlegourdistobegintomovechain,braceletrotationtomovethroughaYe,frictionslabtheratchet,holdfastmountprintintegralwholecommonrevolution,fivetoothmajoraxisesthentheslewingslabgear,toothminoraxisandtheflowerkeyholegearstarttoarouseheavychainwheel,fromriseheavythechainwheelstarttoarouseheavythechainhangupheavything.Keyword:Hoistingmachinery,andhandgourd,starter,braking,geartransmissionII平顶山工业职业技术学院毕业设计说明书（论文）目录摘要...............................................................................................IABSTRACT.........................................................................................II第一章起重机械的分类....................................................................11.1起重机械的分类.........................................................................1第二章手拉葫芦.....................................................................................32.1手拉葫芦的定义.............................................错误！未定义书签。2.2手拉葫芦在工业中的用途及使用场合.............错误！未定义书签。第三章手拉葫芦的机构与结构...............................................................53.1手拉葫芦的机构分类......................................错误！未定义书签。3.2结构...........................................................................................53.3手拉葫芦结构原理.........................................错误...
