哈尔滨理工大学学士学位论文大型H钢翻转提升机构设计摘要我国现如今的工业水平不断地发展，H钢运用的领域越发广泛，在提升和翻转那些笨重、体积很大零件不能只靠人力去完成，为了提高生产效率需要设计出一种设备来解决此问题。在设计的同时需要考虑到传动装置变松以及润滑等问题。本文首先对翻转机提升类型从其特点进行分析到选择，选择出链式翻转机构和液压式提升装置，对H钢翻转工作进行分析，设计出符合要求的元器件如轴，齿轮，皮带等，对部分件进行校核，为了元件相互协调配合，设备运行平稳。最后设计出液压与电气系统组合，从而形成一套完整的工作体系从上升正反翻转、制动、下降。提升机构选择形式为液压式，优点是重量轻、容易实现调速、使用寿命长。缺点是油液对密封装置要求比较严苛容易泄露。翻转机构使用链式传动，优点是摩擦性好、成本低。缺点不耐冲击、质量大。关键词H钢；翻转机构；提升机构-1-哈尔滨理工大学学士学位论文DesignofLargeScaleHSteelLiftingMechanismAbstractChinaisnowthelevelofindustrialdevelopment,Hsteelusedmoreandmorewidelyinthefield,liftingandturningoftheheavyandlargepartscannotonlyrelyonmanpowertocomplete,inordertoimprovetheproductionefficiencyweneedtodesignadevicetosolvethisproblem.Atthesametimethedesignshouldtakeintoaccounttheloosegearandlubricationproblems.Basedontheanalysisofthetypesofhoistingmachineturntochoosefromitsfeatures,chooseachainturnovermechanismandahydraulicliftingdeviceforHsteelturningworkanalysis,designedtomeettherequirementsofthecomponentssuchasshaft,gear,beltandsoon,tocheckthepart,asthecomponentsofcoordination,equipmentrunningsmoothly.Finally,thehydraulicandelectricalsystemiscombinedtoformacompletesystemofwork,fromrising,reverse,brakinganddescending.Theselectionofliftingmechanismishydraulic,withtheadvantagesoflightweight,easyrealizationofspeedcontrolandlongservicelife.Thedisadvantageisthattheoilonthesealingdevicerequirementsaremorestringent,easytoleak.Theturnovermechanismadoptschaintypetransmission,andhastheadvantagesofgoodfrictionandlowcost.Disadvantages,noimpact,highquality.KeywordsHsteel,turnovermechanism,liftingmechanism-II-哈尔滨理工大学学士学位论文目录摘要.......................................................................................................................IAbstract................................................................................................................II第1章绪论.........................................................................................................11.1课题研究的背景及意义.............................................................................11.2国内外研究现状.........................................................................................11.2.1国外发展现状......................................................................................11.2.2国内发展现状......................................................................................21.3本课题的研究内容.....................................................................................4第2章翻转提升机构的总体设计.....................................................................52.1翻转和提升机构采用形式的确定.............................................................52.1.1翻转机构的确定..................................................................................52.1.2提升机构的确定..................................................................................72.2H钢翻转的工作原理...............................................................
