    摘要:

    目前,液压动力头岩心钻机大多采用液压缸给进,液压卷扬机提升。近年来,国外多个国家以液压技术见长的公司,研发了无卷扬机液压缸升降式钻机,它与传统钻机设计理念不同,液压缸不单是给进机构也作为提升机构。这种钻机取消了结构复杂而笨重的卷扬机、天车、游动滑车组。液压缸提升系统井架不承受提升载荷,井架尺寸小,轻便;整个设备体积小、质量轻、成本低、技术经济指标先进。它为研发液压动力头钻机提供了一种新机型。介绍了瑞典山特维克浅钻和挪威MH公司RamRig深孔钻机的结构和其他一些国家研发和应用情况。阐述了双液压缸提升和液压缸-钢丝绳倍速机构两种不同系统的工作原理及应用特点。

    Abstract:

    Hydraulic driving head core drill is mostly fed by hydraulic cylinder and lifted by hydraulic winch. The lifting hydraulic cylinder drill without hoisting winch has been developed in several countries in recent years, which is different from traditional drill design concept with hydraulic cylinder not only as feeding mechanism but also as lifting mechanism. The heavy winch, crane and pulley block with complex structure are saved. The headframe size of hydraulic cylinder lifting system is small and light with no lifting load and the whole drill has advanced technical and economic index. The paper introduced the Sweden Sandvik shallow drill and Norway RamRig deep-hole drill of MH Co. about the structures and the development and application in some other countries; described the working principle and application characteristic of double hydraulic cylinder lifting and hydraulic cylinder-steel rope speed multiplication mechanism.
