I摘要液压凿岩机是一种应用于建筑、采矿和地质工程的凿岩设备，因为效率高、凿岩速度快、环境污染低和易于实现自动化而逐渐取代气动凿岩机。随着计算机技术和机电一体化技术的发展，进一步提高液压凿岩机的凿岩效率，完善自动凿岩技术，成为目前国内外相关研究机构的研究热点。这些研究，将会促进液压凿岩机的进一步发展和应用。本文对液压凿岩机的结构进行改造设计。主要包括对冲击机构、转钎机构的结构设计及液压系统的设计，并对液压凿岩机普遍出现的卡紧问题予以提出了解决方案，及通过对冲击锤开均压槽来实现它的防卡紧作用。目前，我国液压凿岩机的推广处于“瓶颈”阶段，液压凿岩机在矿山开采的广泛使用将会推动矿山机械高效、安全、稳定的发展。关键词液压凿岩机冲击机构转钎机构矿山机械IIAbstractThehydraulicpressurerockdrillisakindofcuttingrockequipmentwhichapplytoarchitecture,miningandgeologicengineering.Thisequipmenthasreplacedpneumaticrockdrillgraduallybecauseit’sapttoberoboticizedandit’shighefficiency,highchiselrockspeed,lowenvironmentpollution.WiththedevelopmentofcomputerscienceandMechatronicstechnique,Toimprovethecuttingrockefficiency,consummatethecuttingrocktechniquehasbecomenewandimportantresearchcontentandwhichwillacceleratethespeedofThehydraulicpressurerockdrill’sdevelopmentandapplications.ThispaperdesignsThehydraulicpressurerockdrill’sconfigurationandchangespartofitsstructure.Includingimpactmechanism,rotarymechanism,andhydraulicpressuresystem.Furthermore,thispapersolvestheproblemof‘clip’and‘defendingclip’andnow,ThehydraulicpressurerockdrillhasnotusedinMiningmachinery,itsapplicationabroadlywillpromotethedevelopmentofMiningmachineryefficiently,safelyandsteadily.KeywordshydraulicrockdrillimpactmechanismrotarymechanismMiningmachineryIII目录摘要...................................................IABSTRACT.................................................II第1章绪论.............................................11.1国内外液压凿岩机发展概况...................................11.1.1国外液压凿岩机发展概况..................................11.1.2国内液压凿岩机发展概况..................................21.2液压凿岩机的基本功能与组成.................................31.3液压凿岩机类型.............................................41.3.1液压凿岩机分类..........................................41.4研究的意义与研究内容.......................................5第2章液压凿岩机的常规设计..............................62.1总体方案设计...............................................62.2活塞的设计.................................................62.3缸体的设计................................................102.3.1液压缸性能参数的计算...................................102.3.2液压缸主要几何尺寸的计算..............................112.4凿岩转钎轴的设计..........................................122.5液压凿岩机回油蓄能器的设计................................152.6转钎齿轮的设计及强度校核..................................192.6.1选择齿轮类型、精度等级、材料及齿数....................192.6.2按齿面接触强度设计....................................202.6.3按齿根弯曲强度计算....................................222.7液压凿岩机卡紧的改进设计..................................242.7.1改进的目的和意义.......................................242.7.2液压卡紧危害...........................................252.7.3改进措施...............................................25第3章液压凿岩机液压系统设计...........................263.1典型系统介绍、分析与比较..................
