剪叉式液压举升机的结构设计与优化 机械制造专业VIP免费

剪叉式液压升降机的结构设计与优化摘要剪叉式液压举升机作为一种上下运输的装置，主要用于抬升重物，在很多领域都有应用。由于其结构简单、工作稳定和维修方便等优点，被广泛应用于车站、机场等设施的维修中，但目前缺乏完整的理论分析方法。本课题主要对其特点进行理论分析、结构设计，液压缸的布置，液压系统设计，主要参数的确定，对其关键部位进行计算与校核。对其部件进行设计计算和强度校核，通过优化结构设计来验证结构设计的合理性。关键词：剪叉式，液压升降机，结构设计，优化IAbstractAsakindofdeviceforupanddowntransportation,thehydrauliclifterismainlyusedforliftingheavyobjects,whichhasbeenusedinmanyfields.Duetoitsadvantagesofsimplestructure,stableworkandconvenientmaintenance,ithasbeenwidelyusedinthemaintenanceofstations,airportsandotherfacilities,butthereisnocompletetheoreticalanalysismethodatpresent.Thisprojectmainlycarriesouttheoreticalanalysis,structuraldesign,layoutofhydrauliccylinder,designofhydraulicsystem,determinationofmainparameters,calculationandverificationofitskeyparts.Thedesigncalculationandstrengthcheckofthecomponentsarecarriedouttoverifytherationalityofthestructuraldesignbyoptimizingthestructuraldesign.KeyWords:Shearforktype,hydrauliclift,structuraldesign,optimization目录II摘要..........................................................................................................................................IIAbstract.....................................................................................................................................III目录........................................................................................................................................IV第1章绪论...............................................................................................................................11.1升降机在生产和生活中的作用和意义.......................................................................11.2升降机国内研究发展情况...........................................................................................11.3升降机国外发展现状和发展趋向...............................................................................31.4课题来源.......................................................................................................................4第2章剪切式液压升降机的结构设计方案……………………………………………….62.1剪切式液压升降机的概述及组成...............................................................................42.1.1剪切式液压升降机的概述................................................................................82.1.1剪切式液压升降机的组成................................................................................82.3剪切式液压升降机的特点及应用...............................................................................42.2.剪切式液压升降机的原理...........................................................................................42.4剪叉式液压升降机的结构设计方案...........................................................................42.4.1升降机结构的设计............................................................................................42.4.2剪叉式液压升降机的结构设计方案................................................................42.4.3升降机机构中液压缸布置方式........................................................................42.5本章小结......................................................
