摘要 针对现有煤矿大直径、长距离水平定向输水孔套管敷设中存在的钻机给进能力不足、给进行程过短、套管规格适应性差等问题,设计了大直径、长套管水平顶管钻机。该钻机采用分体式结构,由箱式液压动力站和撬装式顶管钻机组成,方便运输及井场布局。设计带滑轨支撑的水平伸缩油缸钢丝绳倍速推进系统,在短机身运输长度下实现长给进行程,满足10 m长套管加杆作业需求;设计大扭矩动力头及夹持卸扣器,完成φ219 mm套管接头螺纹强力拧卸扣作业;最终实现10 m长φ219 mm螺纹套管安全高效水平顶管敷设。 In response to the problems of insufficient feed capacity and short feed distance of the drilling rig and poor adaptability of the casing specifications during the laying of large-diameter and long-distance horizontal directional water delivery holes in existing coal mine,a large-diameter and long casing horizontal pipe jacking drilling rig was designed.The drilling rig adopts a split structure,consists of a box type hydraulic power station and a lever mounted top pipe drilling rig,which is convenient for transportation and well site layout.Designed a horizontal telescopic oil cylinder steel wire rope double speed propulsion system with sliding rail support to achieve a long travel distance under short body transportation length,and meet the needs of 10 m long casing rod adding operation.Designed a high torque power head and a clamping and releasing device to complete the operation of forcefully twisting and releasing the threads of the diameter?准219 mm casing joint.Finally achieves safe and efficient horizontal pipe jacking laying with a 10 m long diameter of?准219 mm threaded casing.
