河南理工大学2011毕业设计说明书（论文）摘要液压支架的出现，把回采工作面的支护技术从手工支护发展到机械化支护,它作为回采工作面的一种支护设备，在工作过程中能否取得良好的支护效果，取决于支架的架型，结构和相关参数。本课题主要讲述的是：首先对液压支架作了简单的概述；接着分析了液压支架的选型原则及题目的具体要求；然后根据这些设计准则与计算选型方法按照给定参数要求进行选型设计；接着对所选择的液压支架的液压系统各主要液压元器件进行了选型与设计，这其中底座和四连杆的设计是主要内容，而液压系统的基本回路的设计是液压系统设计的主要内容，它直接关系到液压支架是否能按要求工作，在完成本设计的过程中，利用理论分析的同时，也采用了许多实际经验，做到理论与实践相结合。关键词：支撑掩护式支架四连杆设计底座AbstractSincehydraulicsupportappeared,thetechnologyofsupporthasbeendevelopedformmanualsupporttomechanicalsupportontheworkingface.Thehydraulicsupportdescribedisapartoftheminingindustryequipmentinthemine,usedforprotectionofworkingenvironmentinthegallery.Itworkswellorbadatworkbasingonitssupportmode,frameandsomeparameters.Inthetask,firstly,theoptimalvaluesofsomeparametersoftheleadingfour-barmechanismaredeterminedbyusingVisualBasic.Secondly,ascertainthecapabilityofhydraulicsupport.Nextly,themodelisfoundedwiththetwo-dimensionalsoftware,autoCAD，thethree-dimensionalsoftware,andalsodotheSimulink,SimMechanicsandsimpleanalysis.Thenonthebaseofmechanicmodelofsupport-surrounding,themechanismandloadsonthesupportisdecided.Thenextwork,withtheconditionofthedesign,themainmechanicsofhydraulicsupportisanalyzedandcalculatedbyplaneandspatialmodel.Finally,theunderframe,topbeamcaveshield,wristsandhydrauliccolumnareanalyzedbycalculation.Anddrawoutalltheprocessdrawings.Duringthecourseofdoingthepaper,authornotonlyanalysessomethingtheoretical,butalsoadoptedalotofactualexperiences.Combiningtheoryandpractice.Therefore,thepaperpossessestheoryandpracticalvalue,soitmeasuresuptherequiringofthenationtotheundergraduate.Keywords:ShieldsupportbracketFour-linkdesignBase目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc295804663"摘要PAGEREF_Toc295804663\h1HYPERLINK\l"_Toc295804664"AbstractPAGEREF_Toc295804664\h2HYPERLINK\l"_Toc295804665"前言PAGEREF_Toc295804665\h1HYPERLINK\l"_Toc295804666"1.1国内外研究状况PAGEREF_Toc295804666\h2HYPERLINK\l"_Toc295804667"1.1.1国外概况PAGEREF_Toc295804667\h2HYPERLINK\l"_Toc295804668"1.1.2国内概况PAGEREF_Toc295804668
