DX型钢丝绳芯式带式输送机设计毕业论文.doc

I摘要带式输送机自它诞生以来,经过200多年不断完善和改进,已进入电力,冶金,煤炭,化工,矿山,港口等各行各业之中。其机构简单,输送物料范围广,输送量大,运距长,对线路适应性强,装卸料十分方便,可靠性高,营运费低廉,基建投资省,耗能低,效率高,维修费少。本设计为DX型钢丝绳芯式带式输送机,采用机头双滚筒驱动,在保证滚筒不发生打滑的前提下来传递较大的功率,降低输送带的张力和提高使用寿命。文中根据第二滚筒围包角用足,依此算出输送机的各种参数,进行结构设计。由于倾角较大,按第二滚筒围包角用足进行等驱动功率单元法分配,本设计采用11分配,得出尾部张力最小,根据布置原则,张紧装置一般布置在输送带张力最小处,所以本文采用重载车式张紧装置进行张紧。如今,带式输送机正向长距离、高带速、大功率、大运量的大型化方向发展,使其在煤炭行业得到广泛应用。关键词带式输送机双滚筒驱动张紧IIAbstractThebeltconveyerwithcontinuedevelopmentandimprovementhasenteredalltradesandprofessionssuchaspower,metallurgy,coal,chemicalengineering,mineandportsincebeingbornformorethan200years.Itsconstructionissimple,itisbroadtotransportstockscope,itisbigtotransportquantity,thelengthofhauldistancehasstrongadaptabilityforline,handlingmaterialisveryconvenient,reliabilityishigh,itcanreduceinvestmentinbasicconstruction,highefficiency,lowmaintenancecost.ThedesignisDXmodelcoretypebeltconveyerofwirerope,themachineheaderadoptstwocylinderdrives,inguaranteecylinderdonotoccurtheprerequisitewithslipperydozentransmitgreaterpower,reduceraisingthetensionofbeltconveyerandimproveservicelife.Inwritingaccordingtosecondcylindersurroundbaleangleuseenough,accordingtothisvariousparametersthatmakeconveyerfinally,carryoutstructuraldesign.Sinceinclinationisgreater,accordingtosecondcylinderwaitfordrivewithfootpowerunitlawdistribution,thisdesignadopts11isdistributed,itisminimumtoreachtailtension,basisarrangeprinciple,tensionstationarrangesnormally,isinthetensionminimumplaceofconveyerbelt,so,thispaperusetheburdenvehicletensionequipmenttotighten.Nowbeltconveyersdevelopmenttowardstolongdistance,highbeltspeed,greatpowerandhightransportation,andtheadvantageofthiskindofconveyerrealizeseasily,makeextensiveapplicationincoalindustry.KeywordBeltconveyertwocylinderdrivetightIII目录摘要.........................................................IAbstract........................................................II第1章绪论...................................................11.1前言.................................................................................................................11.2带式输送机的发展史....................................................................................11.2.1国外带式输送机的发展........................................................................11.2.2国内带式输送机的发展........................................................................21.2.3国内外带式输送机的差距....................................................................21.2.4带式输送机的发展趋势........................................................................31.3带式输送机的分类........................................................................................31.4带式输送机的特点及应用............................................................................4第2章带式输送机的整体设计方案..................................52.1方案的确定....................................................................................................52.2工作原理.........................................................................................................7第3章带式输送机的主要部件与功能..............................103.1输送带...........................................................................................................103.1.1输送带的发展.......................................................................................103.1.2输送带的种类及差异..........................................................................103.1.3输送带的要求........................................................................................113.1.4钢丝绳芯输送带....................................................................................113.2拉紧装置.......................................................................................................123.2.1拉紧装置的作用...................................................................................123.2.2拉紧装置的分类及特点......................................................................123.3托辊...............................................................................................................143.3.1托辊的结构及作用...................................................................................14IV3.3.2托辊的选择...........................................................................................143.4清扫装置.......................................................................................................163.4.1清扫器的作用.......................................................................................163.4.2清扫器的形式.......................................................................................163.5传动滚筒、改向滚筒..................................................................................173.5.1传动滚筒的分类...................................................................................173.5.2改向滚筒的选取...................................................................................183.5.3环形胀套...............................................................................................193.6机架的设计与选取......................................................................................203.6.1机头探架..............................................................
