一般岩心钻机均由回转、给进和升降三大主要机构组成.这三大机构实现了液压传动即为全液压式岩心钻机.目前,地质岩心钻机已经发展到第三代,即所谓全液压式岩心钻机.第一代钻机是手把给进式的;第二代钻机是油压给进式的.纵观地质岩心钻机的演变过程可以看出,地质岩心钻机是随着钻井工艺水平的发展而发展的.钻井工艺的中心问题就是在保证钻孔符合地质设计要求的前提下,最大限度地提高钻进效率.因此,首先要求钻机的回转机构和给进机构能满足一定钻进方法和适应不同岩层钻进的需要,其次还要求这些机构特别是升降机构能最大限度地减少辅助作业时间.近百年来,岩心钻机的结构基本上是围绕着如何完善回转、给进、升降这三大问题在演进着的.四
General core drilling rig consists of three main bodies of revolution, feed and lift.These three institutions to achieve the hydraulic transmission is full hydraulic core drilling rig.Currently, the geological core drilling rig has developed to the third generation, the so-called full hydraulic Core drilling rig.The first generation of rig is the handle into the type; The second generation of rig is hydraulic feedthrough.Geological core drilling rig evolution can be seen, the geological core drilling rig is with the development of the level of drilling technology And the development of drilling technology center is to ensure that drilling in line with the geological design requirements under the premise of maximizing the drilling efficiency.Therefore, the first request rig rotary mechanism and feed mechanism to meet certain drilling methods and adaptations Different rock drilling needs, and secondly also requires these institutions, especially the lifting mechanism can minimize the auxiliary work time.In the past century, the structure of the core drilling rig is basically around how to improve the three issues of rotation, feed, lift In the evolution of four
