摘要
为了减少瓦斯灾害,针对松软突出煤层钻孔施工的需求,研制了一款高转速、长行程的ZDY2800LG跨输送带螺旋钻进钻机。介绍了钻机的高转速动力头、长行程给进装置、吊装提升装置、具有保护功能的液压回路等关键技术。经过工业性试验表明:该钻机液压系统先进、搬迁方便、施工效率高,具备在松软突出煤层钻进200m的能力。
In order to reduce the gas disaster, a cross-belt auger drilling rig named ZDY2800LG has been developed, which has high rotation speed and long stroke aiming at the need of drilling in soft coal seam. The key technologies of high rotation speed power head, long stroke feeding device, hoisting and lifting device and hydraulic circuit with protection function were introduced. The industrial tests indicate that the drilling rig has the feathers of advanced hydraulic system,convenient transportation, high efficiency and the capability of drilling 200 m in the soft coal seam.
