摘要 1963年，设计民微型Hydrack钻机。这是一种非常轻而短的钻机，其行程为851mm。采用三速齿轮箱，其最大转矩为691Nm，有效钻孔推力为2145公斤。设计钻杆较小，直径为41.3mm，长为762mm，也带锥形螺纹接头，称为ET/A型钻杆。ET/A型和最初的ET/N型钻杆是抽放瓦斯的两种标准钻孔设备，现已包括在英国煤炭部第613/1974号样本中。 钻机——有一个带滑板的机架，由滑板支撑。钻头安装在滑座上，由液压马达、变速齿轮箱和推力套以及供水旋转接头组成。在机架内滑座下是液压缸。机架上钻孔末端的导向夹持器用来固定和支持钻杆。 Hydrack钻机是由由组标准件装置组成； 动力设备——这是一个装有液压油的油箱，下面有滑橇，便于运输。一台电动机和液压泵及其它辅助设备，如回油过滤器、安全阀、加油泵、油箱通气管以及湿度安全开关都安装在油箱上面。 控制盘——为四个装置中最小的。包含有钻孔功能的控制阀，指示转矩的压力计以及钻头上的钻进压力。 装配式机架——当准备钻孔时，机架支撑着钻机。机架形式多种以适应不同钻孔地形变化，有H型机架、A型机架和单支柱支座。后两项是根据钻机使用者提出来的要求设计的。 液压油通过挠性液压软管从动力装置站输送到控制盘，然后进入钻机。软管一般长4m，能适应各种装置的定位。 关键词：动力设备控制盘装配式机架 ABSTRACT Hydrack gas drilli
