I摘要随着我国经济快速发展,公路上的高级轿车越来越多,道路清障车在作业时开始十分注意对事故车辆的保护,特别对一些高档轿车,应避免因为作业中的捆绑、挤压以及运输中的碰撞造成对事故车辆机件及外观上的进一步损伤。平板一拖二式多功能清障车作为专用清障车的一种,它利用附加的液压绞盘、液压举升装置、平板断开式能够对事故车辆施行装载运输,实现对事故车辆的快速处理,并且不受事故车辆车速的限制,因此对平板一拖二式多功能清障车的主要工作装置进行改装设计计算以及校核,以达到合理。在查阅大量相关资料的基础上,选择平板一拖二式多功能清障车设计的总体方案,对底盘、举升机构、平板机构、托臂机构、液压绞盘以及相关附件等进行了合理选择校核。并通过对底盘型号的选取,确定了整车性能参数。确定了平板一拖二式多功能清障车总体参数。关键词:清障车改装设计;液压绞盘;举升机构;平板机构;托臂机构;校核IIAbstractWiththerapiddevelopmentofoureconomy,moreandmorelimousinecomeintotheroad,atthesametime,thelimousineshouldbecautiouslyprotectedwhentheroadrepaircarswork,especiallyforsomeluxurycars.Greatattentionshouldbepaidtotheaccidentvehicles,whichcanpreventextrusion,collisionandfurtherdamageofthechangeontheappearance.Asakindofspecialrepaircar,thetabletwentontwotypemultifunctionalrepaircarusestheadditionalhydrauliccapstan,hydraulicliftingequipment,platebreakingtohelptheaccidentvehicleload.Itrealizestherapidprocessingoftrafficaccident,andatthesametimetheroadrepaircarswon’tberestrictedbyspeedoftheaccidentvehicle.Otherwise,themainworkofmodificationdesignandcheck-workcanachieveareasonableresult.Onthebasisofalargenumberofrelevantmaterials,thewholeplanofthetabletwentontwotypemultifunctionalrepaircarcanmakecontributiontothereasonableselectionandcheckingofadditionalhydrauliccapstan,hydraulicliftingequipment,theliftingmechanism,flatorganization,armmechanism,hydraulicwinchandrelatedaccessories.Andthroughtothechassistypeselection,itdeterminestheperformanceparametersofthevehicleandthewholeparameterofthetabletwentontwotypemultifunctionalrepaircar..Keywords:Repaircarmodificationdesign;Hydraulicwinch;Liftingmechanism;Flatorganizations;Armmechanism;CheckIII目录1绪论.................................................................11.1研究意义........................................................11.2国内外发展现状..................................................11.3国内外清障车发展趋势............................................22道路清障车总体方案确定...............................................32.1清障车结构形式方案选择..........................................32.2起升机构方案....................................................62.3举升机构方案选择................................................72.4托臂设计方案选择................................................93道路清障车的参数设计................................................103.1参数选定.......................................................103.2底盘的选取.....................................................103.2.1底盘的结构...............................................103.2.2底盘型号的选定...........................................114车架的改装设计......................................................134.1主车架的改造...................................................134.1.1平板机构的初始设计.......................................134.1.2主车架上铰点位置的确定...................................144.1.3主车架的改装处理.........................................144.2主副车架间连接的设计...........................................154.2.1主副车架连接形式的选择...................................154.2.2铰支座与销轴的设计与校核.................................164.3副车架的设计...................................................174.3.1副车架的整体结构形式设计...................................174.3.2横梁距离的设定...........................................174.3.3副车架材料和截面尺寸的选择设计...........................185工作装置的结构设计与校核............................................195.1平板机构设计...................................................195.1.1平板伸缩液压缸的受力分析.................................195.1.2平板机构伸缩液压缸的选用设计.............................195.1.3平板的断开部分尺寸的设计计算.............................205.2举升机构的设计与校核...........................................205.2.1举升机构的结构参数初始选定...............................205.2.2作图法确定举升机构的最终参数.............................215.2.3校核举升液压缸...........................................235.3托臂结构的设计与校核...........................................235.3.1根据参数选取材料和基本元件...............................235.3.2托臂机构的结构形式和尺寸的初始确定.......................23IV5.3.3机构参数的确定与液压缸的选取.............................245.3.4托臂材料与截面尺寸的选择确定.............................255.3.5托臂机构的校核...........................................255.4卷扬机构的选用设计和计算.......................................265.4.1钢丝绳的选用.............................................265.4.2卷筒的初始设计选择........................................265.4.3吊钩的选用.................................................265.4.4最终选用液压绞盘...........................................265.5液压系统设计...................................................275.5.1设计要求.................................................275.5.2液压系统主要参数计算....................................275.5.3拟定液压系统原理图.......................................285.5.4液压元件的选择...........................................28结束语..................................................错误!未定义书签。参考文献................................................错误!未定义书签。致谢....................................................错误!未定义书签。11绪论1.1研究意义清障车全名为道路清障车,又称拖车、道路救援车、拖拽车,清障车主要是由:底盘、起重装置、托举牵引装置、液压系统、电控系统、车体与工具箱等组成,具有起吊、拽拉和托举牵引等多项功能,适用于高速公路、城市道路的清障作业。清障车是指装有道路抢险作业装备的专用汽车。由于汽车在道路上行驶时,故障和事故是不可避免的,特别是在高等级公路上,这种现象时常发生。清障车的任务就是将故障车或事故车及时地拖离现场,确保道路的畅通无阻。因此,道路清障车又称道路抢险车。随着高等级路面和在用汽车的增多,清障车也得到了发展。清障车按类别
