| 摘 要： | 目前煤矿井下瓦斯抽采用全液压动力头式钻机以分体式为主,钻机搬迁费时费力,钻孔施工效率较低,履带式钻机的研制有效地解决了这一问题。从4种新型履带式坑道钻机的研制及现场应用情况看,采用整体式履带车载结构,可在井下自行搬迁,方便快捷,工人劳动强度低;机身倾角调整方便省力,钻机固定安全可靠;钻机设计参数合理,配套高强度钻杆处理卡钻事故的能力强;采用全液压驱动,各执行机构既可实现联动,又可单独控制工作;液压系统采用多泵系统,可独立调节各机构工作参数、转速和扭矩无级调整;采用具有节能效果的负载敏感技术,泵控变量便于实现远程控制,符合钻进工况特性要求,可满足煤矿坑道不同孔深钻探施工需求。

| Abstract: | The all hydraulic rig mainly adopts detachable structure that is used in gas drainage in coal mine gallery.It will take time and need great effort to move the rig and be inefficiency in the drilling construction.The research and manufacture of the track-mounted rig will solve the problems.The research,manufacture and application of four kinds of new gallery track-mounted rig are introduced in this paper.The track-mounted rigs are convenient for moving in underground road and easy for dip adjusting,sage for fixing.The parameter of rig is reliable and is of high capacity for drilling accident solving.The hydraulic system adopts multi-pump system which is easy for con-trol every operation parametevs.The load sensitive technique is adopted,which can control remote operation to meet the requirements of underground drilling. |
