高炉开铁口机大臂旋转设备液压系统设计摘要开铁口机是完成打开高炉铁口的关键设备，随着在现代冶炼技术的发展进步,老式简易开铁口机的不足逐渐暴露出来，已不能满足现代化高炉的要求，开铁口机的改制势在必行。本课题研究的是全液压开铁口机的液压系统设计，该控制系统利用液压控制灵活、迅速的优势，一改以往人工操纵换向为液压系统识别自动控制换向。开铁口机从回转开始工作到工作结束回到停放位置，均采用液压全自动控制，不需人工干预，提高了开孔能力和开孔速度，适应了现代化大型高炉的要求。该系统主要由冲击、转钎、推进及回转四部分的液压控制系统组成，本课题主要设计了这四部分中推进与回转部分的液压控制系统，及对这两部分液压系统的组合和系统性能验算，同时论述了各部分的计算设计过程和必要的强度校核。关键词开铁口机；液压系统设计；液压全自动控制ABSTRACTTapholedrillisakeyequipmenttoopenthetapholeblastfurnace,Withmodernsmeltingtechnologyinthedevelopmentandprogress,Easyopenoldirondeficienciesmachinegraduallyexposed,Hasbeenunabletosatisfytherequirementsofmodernblastfurnace,Tapholedrillrestructuringinevitable.Thistopicresearchisentirehydraulicpressureopenstheirongatemachinehydraulicsystemdesign,Thecontrolsystemuseshydrauliccontrolflexibility,rapidadvantages,assoonaschangedformerlythemanualcontrolcommutationforthehydraulicsystemrecognitionautomaticcontrolcommutation.TheTapholedrillerfromthebeginningoftheendoftheworktoreturntotheworkspaceforparking,adoptedhydraulicautomaticcontrol,doesnotneedthemanualintervention,enhancedhasopenedtheholeabilityandopenstheholespeed,adaptedthemodernizedlarge-scaleblastfurnacerequest.Thissystemmainlyoftheimpact,theextensionrockdrill,advancesandrotatesfourpartofhydrauliccontrolsystemcomposition,Thedesignofthetopicsissuesofthispartofthefourhydraulicsystems,Andthetotalhydraulicsystem,thecompositionandpropertiesofcheckingsystem,Italsoexplainsthepartsofthedesignprocessandcalculatingthenecessarystrengthcheck.Keywordstapholetrill；hydraulichystemdesign；hydraulicsystemrecognitionautomaticcontrolcommutation目录摘要.......................................................IABSTRACT......................................................II目录.....................................................III1绪论..........................................................11.1开铁口机国内发展现状...............................................11.1.1开铁口机国内引入状况..........................................11.1.2开铁口机国内开发状况..........................................11.1.3开铁口机国外的应用与发展状况..................................21.2国内外开铁口机存在的问题...........................................21.3开铁口机的发展前景.................................................31.3.1国内各结构开铁口机应用情况....................................31.3.2国际开铁口机的发展趋势........................................31.4全液压开铁口机.....................................................31.4.1全液压开口机简介..............................................31.4.2全液压开口机的发展前景........................................32.本课题的总体设计方案........................................52.1设计要求...........................................................52.2设计方案...........................................................52.3推进部分液压系统的设计.............................................53.液压马达各参数的确定.........................................73.1确定参数........................................................
