  主要特点

  1、立轴钻机的价格:因为钻机的主传动仍为机械传动,零部件制造成本较低,其价格只有国产全液压动力头钻机价格的六分之一、进口全液压动力头钻机价格的十五分之一:

  2、全液压动力头钻机的功能:钻机具有较大立轴通孔直径及较长的给进行程,配备用上、下两个卡盘及圆卡瓦,可实现不停回转连续给进,采用无主动钻杆、不让车、不提出孔内钻杆及在水龙头下端直接加接钻杆的工作过程,完全达到液压动力头钻机工作及加接钻杆的工作过程。配备斜塔完全可以进行各种角度的斜孔钻进施工;

  3、高于全液压动力头钻机的功效:因为加接钻杆的过程同全全液压动力头钻机完全一致,避免了以往立轴钻机频繁停机倒杆、提出主动钻杆加接钻杆而造成的损伤钻头唇面、岩心容易堵塞、减少了加杆时经常将孔底钻具提离孔底而引起的孔内坍塌掉块及事故隐患。另外,全液压动力头钻机提下钻的辅助时间要比立轴钻机多1-1.5倍,而且劳动强度增大。

  4、较低的使用及维修成本:液压传动效率比机械传动效率低是当前难以改变的科学事实,因此相同钻深能力的全液压动力头钻机配备的动力是机械传动立轴钻机的2.5倍。例如:目前国内外1000m全液压动力头钻机配备的动力为132-148千瓦,而1000m立轴钻机配备的为55千瓦(含水泵动力)。根据柴油机的技术参数,理论计算,完成千米钻孔,全液压动力头钻机比立轴钻机多消耗柴油4-5吨,即千米工作量动力费用多支出2万多元。另外,一旦全液压动力头钻机的液压系统发生故障,现场施工人员一般较难排除,更换一台液压泵费用可以购买半台立轴钻机。

  YB-4不停车倒杆动力头可与XY-4、XY-44、JU-1000、XY-5等钻机进行改装,形成XYB-44、XYB-5不停车倒杆钻机等机型。

  此款不停车倒杆、长行程连续给进立轴钻机,采用无主动钻杆、不让车及机上加杆的工作过程,无疑将是所有钻探施工用户、钻探市场及价格竞争激烈、节能降耗已成全球各行各业必追求然的趋势下而立足于地质钻探市场的一种选择。
