设计题目：辉煌型煤厂物流资源配置优化研究摘要液压支架是综合机械化采煤工作面的关键设备。作为安全保护设备，应确保其它综采设备和操作人员有一个安全可靠的工作空间，因而，它的工作性能的好坏直接影响到综采设备整体效能的发挥和人身安全。本次毕业设计主要是根据某矿井井下实际情况，设计出适于中厚煤层使用的支撑掩护式液压支架。该液压支架具有独特的结构特点，如顶梁、掩护梁均设有侧护板，侧护板配有弹簧筒和侧推千斤顶，能较好地起到防夹矸、防倒和防滑的作用，且液压控制系统简单易操作。支架四连杆机构的前连杆采用了单杆式，后连杆采用整体式，既增大了有效的工作空间，又起到了有效的防矸作用。支架的底座采用左右对分式，且前端做成滑橇形，既可适应底板起伏不平的变化，又可减少支架的移架阻力，避免移架时产生底座啃底的现象。在液压系统的设计中，液压阀、管件均采用国内支架通用的液压元件。支架的推移结构采用推移框架式结构，实现了移架力大于推溜力。关键词：液压支架；支撑掩护式；四连杆机构；推移框架式居中，黑体，小二，字间空两个格字间空两个格空一行正文宋体，小四，间距：单倍用分号符隔开要求3~5个关键词AbstractPoweredSupportisthekeyequipmentofthesyntheticalmechanizedlongwallfaceincoalmining.Asthesafetyfacility,PoweredSupportshouldensurethesafetyworkingspaceforthetheworkersandotherequipments.Therefore,whetheritsworkingpropertyisgoodornot,ithasagreateffectontheworkers’safetyandintegralefficiencyofthesyntheticalmechanizedcoalminingfacility.Accordingtotherealsituationsinonecoalminingsomewhere,achockshieldhydraulicsupportisdesignedforthemediumcoalbed.Thestructureofthehydraulicsupporthasauniquecharacteristics,forinstance,thecanopyandshieldarefurnishedwithsideprotectingplateswhichconsistofspringcolletsandsidefluidpressureoperatedjacksinordertoprotectthesupportfromfallingandsliding.Whatismore,thehydrauliccontrolsystemiseasytomakeandoperate.Inthishydraulicsupport,themechanismoffour-barconnectingrod,withsinglefrontrodandintegralbacklink,increasestheeffectiveworkingspaceandpreventstherocksfallingintotheequipment.Thestructureofbaseisright-and-leftsplitwithasledfront-endtopreventthebasefromnibblingontheground,whichcanadjustthesupporttosuitthefluctuatinggroundandreducemotionalresistance.Inthedesignofhydraulicsystem,thepushingskeletonstructureisusedinthesupporttomakethepushingforcebiggerthanthepullingforcethatfluidpressureoperatedjacksactsonconveyer.Finally,universalfluidpressurecomponents,suchasvalvesandpipes,areappliedinthedesignoffluidpressuresystem.Keywords：hydraulicSupport；chockChield；hydraulicsupport；four-BarconnectingRod居中，TimesNewRoman，小二，加粗TimesNewRoman，小四要顶格书写用分号符隔开空一行目录摘要..............................................................................................................................ⅠAbstract..........................................................................................................................Ⅱ第1章项目研究背景...............................................Error:Referencesourcenotfound第2章存在的问题分析...........................................Error:Referencesourcenotfound2.1人员存在的问题............................................................................................2.2机器和物料存在的问题................................................................................2.2.1机器摆放不合理.........................................................................................2.2.2物料流动不合理........................................................
