ZY32001535液壓支架設(shè)計(jì)說明書畢業(yè)論文.doc

大學(xué)學(xué)士學(xué)位論文I摘要本課題主要論述了液壓支架的主要設(shè)計(jì)過程。其中包括：液壓支架的選型、總體設(shè)計(jì)、主要零部件的設(shè)計(jì)、校核以及液壓系統(tǒng)設(shè)計(jì)。支架的形式為掩護(hù)式支架。支架除了要有效的對(duì)頂板進(jìn)行有效支撐，還要實(shí)現(xiàn)升、降、推移四個(gè)步驟。支架采用四連桿機(jī)構(gòu)，改善支架的受力狀況，縮小支架的升降過程中頂梁前端前后移動(dòng)的距離。立柱采用單伸縮液壓缸，前端帶有加長(zhǎng)桿，以滿足支架最低及最高位置時(shí)的高度要求。頂梁掩護(hù)梁、底座都做成箱體結(jié)構(gòu)用鋼板焊接而成。在研制液壓支架時(shí)，需要對(duì)支架進(jìn)行生產(chǎn)試驗(yàn)和分析研究，確定合理的液壓支架受力參數(shù)、運(yùn)動(dòng)參數(shù)和結(jié)構(gòu)參數(shù)，以及選定液壓支架最佳方案等方面綜合性的科學(xué)技術(shù)問題。本設(shè)計(jì)主要從支架的工作原理這手，然后進(jìn)行總體結(jié)構(gòu)設(shè)計(jì)以及校核。關(guān)鍵詞：液壓支架；頂梁；底座；立柱；結(jié)構(gòu)設(shè)計(jì)大學(xué)學(xué)士學(xué)位論文IIABSTRACTThearticlemianlyelaboratethehydraulicsupportdesignfortop-caving.includes:theselectionofhydraulicpressuresupportform,systemdesign,mainsparpartdesignandexaminationofhydraulicsystemdesignThesupporteliminatesmustrealizeeffectivelycarriesonthestruttotheroof,butalsomustrealize,tofall,topush,movefoursteps.thesupportusesfourlinkmotiongears,improvesthesupportthestresscondition,reducesthesupporttoriseandfullthedistancewhichintheprocessfortendthetop-beamaroundmoves.Thecolumnusesthelistexpansionandcontractionhydrauliccylinder,frontendhaslegthensthepole,satisfiesthesupporttobelowestandtimethehighestpositionhighrequest.Thetop-beam,shieldsLiang,thefoundationallmakesthepackedinaboxbodystructure,becomeswiththesteelplatewelding.Atresearchtopressesthesupport,needtocarryonproducetoexperimentandanalyzetheresearch,makesurereasonableofliquidpressesthesupporttobesubjectedtothedintparameter,thesportparameterandthestructureparameters,andmakeselectiontheliquidtopressthesyntheticsciencetechniqueproblemofaspectofetc.ofthebestprojectofsupport.Thisdesignmainlythishandfromtheworkprincipleofthesupport,thencarryonthetotalstructuredesignandschoolpits.Keyword:Hydraulicpressuresupport；Topbeam；Cradle；thecolumn-typesupport；structuredesign大學(xué)學(xué)士學(xué)位論文III目錄摘要IABSTRACTII1緒論11.1國(guó)內(nèi)外液壓支架的研究現(xiàn)狀及發(fā)展11.2本課題的研究目的和意義32液壓支架基本理論分析52.1液壓支架的工作原理52.2液壓支架的類型和結(jié)構(gòu)82.3對(duì)液壓支架的基本要求92.4支架的選型設(shè)計(jì)103液壓支架的整體結(jié)構(gòu)設(shè)計(jì)143.1支架高度、中心距的確定143.2底座長(zhǎng)度的確定153.3四連桿機(jī)構(gòu)的設(shè)計(jì)163.4頂梁長(zhǎng)度計(jì)算224支架主要部件的設(shè)計(jì)244.1支架主要部件的設(shè)計(jì)要求244.2頂梁的設(shè)計(jì)254.3底座的設(shè)計(jì)264.4支架技術(shù)參數(shù)和立柱的設(shè)計(jì)264.5力柱柱窩位置和受力計(jì)算334.6千斤頂技術(shù)參數(shù)的確定35大學(xué)學(xué)士學(xué)位論文IV5支架受力分析與計(jì)算415.1支架工作狀態(tài)415.2受力計(jì)算425.3頂梁載荷分布456液壓支架的強(qiáng)度校核476.1強(qiáng)度條件476.2主頂梁的校核476.3掩護(hù)梁強(qiáng)度校核506.4底座強(qiáng)度
