GCPS—20型复合式多功能钻机设计毕业论文.doc

I摘要GCPS20型钻机是一种复合式多功能钻机，为适应我国深基础工程和连续墙以及水利工程、桥梁工程的发展与需要，结合大口径钻机灌注桩和地下连续墙施工的特点，为解决在复杂地层、硬岩中成孔而研制，特别卵石层、基石、漂石层能大幅度提高施工效率，在各种成孔方法中是比较经济有效的方法。钻机是集回转、冲击钻进工艺于一体的多功能复合型钻机，用转盘回转钻进时可用于第四世纪覆盖层，冲击钻进时可用于卵石、灰岩、花岗岩等硬岩地层。本钻机的特点是结构简单，紧凑，而且各种操作手柄布置合理，操作简单，便于使用与维护。关键词：冲击钻进变速箱减速器转盘IIAbstractThetypesGCPS-20drillthemachineisakindofcompoundtypemulti-functiondrillthemachine,inordertoadapttheourcountrydevelopmentanddemandsofthedeepfoundationandconsecutionwallandmarinehydraulicengineering,thebridgeengineering,combinethebigcalibertodrillthemachinetoinfusetonotethestakeandthecharacteristicsofundergroundcontinuouswallconstruction,inordertosolvetobecometheborebutresearchtomanufactureincomplicatedgeologicstrata,hardrock,significantexaltationofabilityofspecialeggstonelayer,sill,thestonelayerconstructionefficiency,isamoreeconomicvalidmethodinvariouslybecometheboremethod.Drillthemachineistogathertheturn-overandpoundattodrillintothecraftintheintegralwholeofmulti-functionandcompoundtypedrillthemachine,canusedfortooverlaythelayerthefourthcenturywhileusingtoturnthedishturn-overtodrillinto,canusedforthehardrockgeologicstrataofeggstone,ashrock,granite.etc.whilepoundingattodrillinto.Drillthecharacteristicsofthemachineoriginallyisastructuresimple,tightlypacked,andvariousoperationhandhandlearrangereasonable,operateinbrief,easytousageandsupport.IIIKeyword：TheimpactdrillintoBecomesoonboxDeceleratethemachineTurnthedishIV目录摘要IAbstractII第1章绪论11.1项目的研究意11.2国内外科技现状11.3设计产品的用途和应用领域1第2章钻机的总体设计22.1总体布局设计22.1.1传动系统22.1.2气动系统22.1.3电气系统22.1.4工具系统22.1.5各部件的功能22.2主要设计参数32.3主要性能特点4第3章动力机确定53.1按钻头钻进所需功率计算53.2按钻机冲击钻进所需功率计算7第4章带轮选择9第5章变速箱的设计及计算125.1变速箱的结构特点125.2结构计算125.2.1初步选定125.2.2选定变速箱传动公比125.2.3按弯曲强度
