岩心钻机改进的一些设想

Some Concepts on Modification of Core Drills

分析了岩心钻机的功用、结构、效能 ,从钻进工艺的要求出发 ,通过实践试验 ,分析了岩心钻机的驱动、传动系统的问题 ,论述了钻机型式 ;最后提出按浅、中、深不同孔深分挡考虑岩心钻机型式的意见。

This paper reviews the use, structure and capability of the core drill. The problems with the drive and transmission systems of the core drill are examined through field tests in the view of the requirements of the drilling process. The versions of core drills are introduced. It is suggested that the version of core drill be considered in shallow, medium deep and deep catalogues.
