摘要
近年来非开挖钻机飞速发展,水平定向钻进及导向钻进技术在管道建设中占主导地位。着重介绍了目前国内外水平定向钻机的动力头传动和驱动方式,给进机构的给进方式,夹持-拧卸装置、底盘、钻杆装卸装置的机构,并分析了它们的优缺点。
In recent years, horizontal directional drilling rig and oriented drilling technology play dominant role in pipeline construction with the rapid development of trenchless drilling machine. The paper emphatically introduced current horizontal directional drilling rig both in China and abroad about the transmission and driving mode of the power unit, feeding mode of feeding mechanism, clamping and loosing device, the chassis and the mechanism of drill stem mounting ＆ dismounting device with the analysis on their advantages and disadvantages.
