兰州交通大学毕业设计（论文）-I-摘要随着社会和经济技术的发展，电气化铁路的发展也越来越迅速。我国对能够适用于电气化铁路的接触网也提出了相关的要求。本设计的目的是完成嘉峪关车站接触网平面设计，同时按要求绘制接触网设备装配图和平面图。首先对设计地区的气象条件资料进行收集，根据铁路目标速度对线索材料进行了选择，再确定其悬挂类型。根据气象条件及线索材料计算负载。其次，根据最大受风偏移计算得到最大跨距；根据规程规定的锚段长度选择锚段，使其张力差要满足要求。然后，对硬横跨进行分析选择。考虑到接触网将来可能的改进及预留，根据计算结果对接触网进行了相应的调整，以使本设计满足电气化铁路的技术要求。最后在上述原理的基础上，对嘉峪关车站接触网进行CAD平面设计，并对具有代表性的支柱进行了容量的校验计算。在接触网平面图的表格栏里对地质情况、支柱类型、安装图号、侧面限界等进行相应的说明。本论文以接触网的基本技术原理为核心，以实际线路状况为依据，对嘉峪关车站的接触网布置进行了平面设计，基本满足电气化铁路的技术要求。关键词：接触网；平面设计；车站兰州交通大学毕业设计（论文）-II-AbstractWiththedevelopmentofsocialandeconomicaltechnology,theelectrifiedrailwayisdevelopingmoreandmorerapidly.Ourcountryalsomakesarelatedrequestforcatenaryofelectrifiedrailway.ThisdesignisintendedtocompletegraphicdesignofcatenaryforJiayuguanstation,andtodrawitsdeviceassemblydrawingandgraphicdraft.Firstly,thesuspensionwasselectedaftertheJiayuguanweatherconditioninformationwascollectedandcluematerialwassift.Theloadwascalculatedaccordingtoweatherconditionandcluematerial.Secondly,themaximumoutreachisobtainedfromthewindshift.Anchoringsectionischosenaccordingtospecifiedanchoringsectiontosatisfytensiondifference.Then,portalstructurewasanalyzed.Thethesisconsideringtheimprovementandreserveinthefutureofcatenarycarriesoutsomecorrespondingadjustmentsforthedesignofcatenaryaccordingtotheresultofcalculation,sothatthedesigncouldbecontentedwiththetechnicalrequirementsoftheelectrifiedrailway.Finally,onthebasisoftheaboveprinciple,thisthesisconcentratedonthegraphicdesignofJiayuguanstationwithCAD,alsoconductedcheckcomputationfortypicalcapacityofthepillars.Graphicdesignofcatenaryintheformcolumnonthepillartype,geology,sidegauge,installthecorrespondingfigurenumberandotherinstructions.Basedonthebasictechnicalprincipleofcatenaryandaccordingtotheactualrailwaycondition,thisthesiscompletedgraphicdesignofcatenaryforJiayuguanstation,whichcouldmetthebasictechnologicaldemandofelectrifiedrailway.KeyWords:Catenary,Station,Graphicdesign兰州交通大学毕业设计（论文）-III-目录摘要.....................................................................................................................................IAbstract......................................................................................................................................II目录..................................................................................................................................III1绪论........................................................................................................................................11.1工程背景.....................................................................................................................11.2设计范围.....................................................................................................................11.3设计目标.....................................................................................................................11.4设计依据.....................................................................................................................11.5本设计的主要工作.....................................................................................................12气象资料................................................................................................................................33设计计算................................................................................................................................43.1主要线材选用.............................................................................................................43.2接触网波动速度的计算.............................................................................................43.3接触悬挂类型及相关参数的选择.............................................................................53.4接触网设计负载计算.................................................................................................53.4.1自重负载..........................................................................................................53.4.2冰负载..............................................................................................................63.4.3风负载..............................................................................................................63.4.4合成负载..........................................................................................................73.5接触网设计实际最大跨距计算.................................................................................73.6全补偿链形悬挂锚段长度的计算.............................................................................83.6.1直线区段..........................................................................................................83.6.2曲线区段..........................................................................................................93.7嘉峪关车站硬横跨结构...........................................................................................104绘制嘉峪关车站接触网平面设计图..................................................................................114.1放图..................................................................................................
