商丘学院本科毕业设计I摘要装载机是一种用途非常广泛的工程机械，属于通过在支座前端安装一个完整的铲斗支撑结构和连杆，跟着机器向前运动进行装载挖掘，并且提升、运输和卸载的自行式机械。它广泛用于公路、铁路、建筑、水电、港口和矿山等工程领域。本设计采用先进的方法和现代设计理念,装载机工作装置总体设计和组件的设计,设计的目的是让读者来对装载机工作装置液压系统设计进行进一步的了解。包括关键部位装载机工作装置，例如铲斗，吊杆，铲斗缸和连杆机构，提升缸等，和应力分析和强度检查中的重要部分。装载机的工作装置和转向机构都采取液压传动，液压系统对装载机工作装置十分重要，本次设计只是分析了工作装置的液压系统，并得出该液压系统的工作油路运行图。关键词:装载机;铲斗;工作装置;液压系统商丘学院本科毕业设计IIAbstractLoaderisaveryversatileengineeringmachinery,belongtoinstallafullbucketbybearingthefront-endsupportstructureandtheconnectingrod,followmachineforloading,tomoveforwardandascend,transportandunloadingofself-propelledmachinery.Itiswidelyusedinhighway,railway,building,waterandelectricity,ports,andminingandotherengineeringfields.Thisdesignadoptstheadvancedmethodandmoderndesignidea,overalldesignandthedesignofthecomponents,workingequipmentofloaderdesignpurposeistoletreadersandhydraulicsystemdesignforfurtherunderstandingoftheworkingequipmentofloader.Includingthekeypartsoftheloaderworkingdevice,suchasbucket,derrick,bucketcylinderandconnectingrodmechanism,improvecylinder,etc.,andthemostimportantpartofstressanalysisandstrengthcheck.Loader'sworkingdeviceandsteeringmechanismtoadopthydraulictransmissionandhydraulicsystemareimportantinloadmechanic,thisdesignonlyworkdeviceofthehydraulicsystemareanalyzed,andconcludedthatthehydraulicsystemofthefuellinerunningwork.Keywords:Loader;Bucket;Workingdevice;Thehydraulicsystem商丘学院本科毕业设计III目录1装载机的发展及应用...............................................................................................................11.1装载机的概论..................................................................................................................11.2装载机的发展和前景......................................................................................................11.2.1国外装载机发展趋势.............................................................................................11.2.2我国装载机的发展前景.........................................................................................22装载机的工作装置原理...........................................................................................................22.1装载机工作装置功能需求..............................................................................................22.2方案..................................................................................................................................23参数的确定及装置设计...........................................................................................................33.1铲斗基本参数的确定......................................................................................................33.2工作机构连杆系统的尺寸参数设计..............................................................................53.2.1转斗油缸后置式反转六杆机构.............................................................................53.2.2工作装置结构设计.................................................................................................63.2.3动臂设计.................................................................................................................63.2.4连杆机构设计.........................................................................................................84工作装置的受力分析与强度校核...........................................................................................94.1铲斗重量计算..................................................................................................................94.2工作装置的受力分析....................................................................................................104.2.1工况水平偏载计算...............................................................................................104.2.2工况垂直偏载计算...............................................................................................124.3动臂的强度校核............................................................................................................134.4铰销的强度校核............................................................................................................164.5连杆的强度校核............................................................................................................174.6摇臂的强度校核............................................................................................................185工作装置液压系统设计.........................................................................................................215.1转斗油缸的选择及其作用力的确定............................................................................215.2动臂油缸的选择及其作用力的确定............................................................................23商丘学院本科毕业设计IV5.3液压系统的设计............................................................................................................255.3.1工作油路的分析...................................................................................................255.3.2工作装置油路设计...............................................................................................266结论.........................................................................................................................................26参考文献.................................................
