DX型鋼絲繩芯式帶式輸送機設(shè)計畢業(yè)論文.doc

I摘要帶式輸送機自它誕生以來，經(jīng)過200多年不斷完善和改進，已進入電力，冶金，煤炭，化工，礦山，港口等各行各業(yè)之中。其機構(gòu)簡單，輸送物料范圍廣，輸送量大，運距長，對線路適應(yīng)性強，裝卸料十分方便，可靠性高，營運費低廉，基建投資省，耗能低，效率高，維修費少。本設(shè)計為DX型鋼絲繩芯式帶式輸送機，采用機頭雙滾筒驅(qū)動，在保證滾筒不發(fā)生打滑的前提下來傳遞較大的功率，降低輸送帶的張力和提高使用壽命。文中根據(jù)第二滾筒圍包角用足，依此算出輸送機的各種參數(shù)，進行結(jié)構(gòu)設(shè)計。由于傾角較大，按第二滾筒圍包角用足進行等驅(qū)動功率單元法分配，本設(shè)計采用1:1分配，得出尾部張力最小，根據(jù)布置原則，張緊裝置一般布置在輸送帶張力最小處，所以本文采用重載車式張緊裝置進行張緊。如今，帶式輸送機正向長距離、高帶速、大功率、大運量的大型化方向發(fā)展，使其在煤炭行業(yè)得到廣泛應(yīng)用。關(guān)鍵詞帶式輸送機雙滾筒驅(qū)動張緊IIAbstractThebeltconveyerwithcontinuedevelopmentandimprovementhasenteredalltradesandprofessionssuchaspower,metallurgy,coal,chemicalengineering,mineandportsincebeingbornformorethan200years.Itsconstructionissimple,itisbroadtotransportstockscope,itisbigtotransportquantity,thelengthofhauldistancehasstrongadaptabilityforline,handlingmaterialisveryconvenient,reliabilityishigh,itcanreduceinvestmentinbasicconstruction,highefficiency,lowmaintenancecost.ThedesignisDXmodelcoretypebeltconveyerofwirerope,themachineheaderadoptstwocylinderdrives,inguaranteecylinderdonotoccurtheprerequisitewithslipperydozentransmitgreaterpower,reduceraisingthetensionofbeltconveyerandimproveservicelife.Inwritingaccordingtosecondcylindersurroundbaleangleuseenough,accordingtothisvariousparametersthatmakeconveyerfinally,carryoutstructuraldesign.Sinceinclinationisgreater,accordingtosecondcylinderwaitfordrivewithfootpowerunitlawdistribution,thisdesignadopts1:1isdistributed,itisminimumtoreachtailtension,basisarrangeprinciple,tensionstationarrangesnormally,isinthetensionminimumplaceofconveyerbelt,so,thispaperusetheburdenvehicletensionequipmenttotighten.Nowbeltconveyersdevelopmenttowardstolongdistance,highbeltspeed,greatpowerandhightransportation,andtheadvantageofthiskindofconveyerrealizeseasily,makeextensiveapplicationincoalindustry.KeywordBeltconveyertwocylinderdrivetightIII目錄摘要.IAbstract.II第1章緒論.11.1前言.11.2帶式輸送機的發(fā)展史.11.2.1國外帶式輸送機的發(fā)展.11.2.2國內(nèi)帶式輸送機的發(fā)展.21.2.3國內(nèi)外帶式輸送機的差距.21.2.4帶式輸送機的發(fā)展趨勢.31.3帶式輸送機的分類.31.4帶式輸送機的特點及應(yīng)用.4第2章帶式輸送機的整體設(shè)計方案.52.1方案的確定.52.2工作原理.7第3章帶式輸送機的主要部件與功能.103.1輸送帶.103.1.1輸送帶的發(fā)展.103.1.2輸送帶的種類及差異.103.1.3輸送帶的要求.113.1.4鋼絲繩芯輸送帶.113.2拉緊裝置.123.2.1拉緊裝置的作用.123.2.2拉緊裝置的分類及特點.123.3托輥.143.3.1托輥的結(jié)構(gòu)及作用.14IV3.3.2托輥的選擇.143.4清掃裝置.163.4.1清掃器的作用.163.4.2清掃器的形式.163.5傳動滾筒、改向滾筒.173.5.1傳動滾筒的分類.173.5.2改向滾筒的選取.183.5.3環(huán)形脹套.193.6機架的設(shè)計與選取.203.6.1機頭探架.203.6.2中間支架.20第4章帶式輸送機的設(shè)計計算.214.1設(shè)計參數(shù).214.2根據(jù)實際輸送量計算帶寬.214.3運行阻力.234.4牽引力及運行功率.284.5輸送帶張力計算.294.6輸送帶強度驗算.314.7滾筒直徑的確定.314.8驅(qū)動裝置的選型及計算.324.8.1電動機
