I摘要刮板输送机是一种具有挠性牵引机构的连续运输机械，主要供采煤工作面使用。在煤矿井下综采工作面中主要承担的任务是将采煤机采下的原煤连续不断地运往转载机，确保综采工作面的原煤连续运出。它要求机身高度小，便于装载；运输能力满足使用地点的生产需要；结构坚固，能抵抗压、砸和碰撞；变更运输距离时，加长和缩短方便；能够不拆卸用机械移置。根据所给设计参数和工作环境的要求，通过对刮板输送机的发展情况、发展趋势、结构组成、工作原理、种类及作用进行分析，对SGD730/180型刮板输送机输送能力的计算、水平弯曲段几何参数的计算、运行阻力的计算、链条张力和牵引力的计算、电机功率的计算、溜槽推移阻力的计算、链条预张力和紧链力的计算及链条强度的计算等，完成刮板输送机结构改进，绘制了SGD730/180型刮板输送机总图、机头传动装置等结构设计。完成了TheuseofScraperconveyor的翻译工作。关键词刮板输送机结构设计理论计算IIAbstractScraperconveyorisakindofflexibletractionforthetransportmachinery,Primarilyfortheuseofcoalface.FullymechanizedcoalmineinthecoalfaceofthemaintasksistoundertaketheminingofcoalShearercontinuouslyreproducedtothemachine,Ensurethatthefullymechanizedcoalfaceofthecoalforexport.Itrequiresahighdegreeofthefuselageofsmall,easyloading;Theuseoftransportcapacitytomeettheneedsofproductionsites;Solidstructure,canresistpressure,smashingandcollision;Changethedistance,thelengtheningandshorteningtheconvenience;cannotdemolishedbymechanicalremoval.Accordingtothedesignparametersandenvironmentalrequirements,thescraperconveyorthroughthedevelopmentofthesituation,thetrendofdevelopment,structure,workingprinciple,typesandrolesoftheSGD730/180-scraperconveyortransportcapabilityofcalculation,Thelevelofthebendingofthegeometricparameters,theoperationoftheresistance,thechaintensionandthetraction,electricalpower,theresistancetopassageofthechute,thechainofpre-tensionandtightlinksofthechainofcalculationandthecalculationofstrength,tocompletescratchBoardconveyorstructureimprovement,drawn-scraperconveyorSGD730/180themap,thenosegear,suchasstructuraldesign.CompletedTheuseofScraperconveyorofthetranslationwork.KeywordsScraperconveyorStructuralDesignTheoreticalcalculationsIII目录摘要...................................................................................................................IAbstract.................................................................................................................II第1章绪论.......................................................................................................11.1选题意义..................................................................................................11.2刮板输送机概述......................................................................................11.3国内外发展情况......................................................................................21.3.1我国刮板输送机发展现状...........................................................21.3.2国外刮板输送机发展概况...........................................................41.4刮板输送机的发展趋势..........................................................................41.5刮板输送机改进......................................................................................51.5.1刮板输送机的主要问题...............................................................51.5.2刮板输送机的改进.......................................................................5第2章刮板输送机分类及作用.......................................................................72.1刮板输送机的分类..................................................................................72.1.1按刮板链的形式分类...................................................................72.1.2按卸载方式分类...........................................................................82.1.3按中部槽结构分类.......................................................................92.1.4按采煤机牵引方式分类.............................................................102.2刮板输送机作用....................................................................................10第3章刮板输送机组成及作用.....................................................................123.1组成部分................................................................................................123.2机头传动部和机尾传动部....................................................................133.2.1机头部和机尾部结构.................................................................133.2.2减速器.........................................................................................143.2.3减速器联接盘.............................................................................153.2.4紧链器（闸盘式）及紧链装置.................................................153.2.5电动机联接盘.............................................................................183.3机身结构................................................................................................183.4过渡槽....................................................................................................19IV3.4.1机头过渡槽.................................................................................193.4.2机尾过渡槽.................................................................................193.5中部槽、调节槽....................................................................................203.5.1中部槽.........................................................................................203.5.2调节槽.........................................................................................213.6刮板链及调节链....................................................................................213.7挡板.......................................................................
