为满足地面煤层气抽采孔、电缆孔和矿山地面救援孔的施工需要,研制了一款适用于煤层气车载钻机的多功能动力头。该动力头采用双速液压马达一级齿轮减速驱动主轴回转,结构紧凑、传动效率高、主轴通径大、转速扭矩调节范围广且具有主轴制动功能,可适用于空气潜孔锤、气举反循环和定向钻进等多种钻探工艺。现场试验表明,该动力头能力大,效率高,功能全且易操作,为高效安全钻井施工提供设备保障。
In order to meet the construction needs of ground CBM gas drainage holes, cable holes and mine ground rescue holes, a multifunctional power head suitable for CBM drilling rig was developed. The power head adopts two-speed hydraulic motor and a gear reducer drives the spindle to revolve. The utility model has the advantages of compact structure, high transmission efficiency, large spindle diameter, wide rotating torque adjustment range and spindle brake function, and is applicable to air hammer, gas lift Reverse circulation and directional drilling and other drilling processes. Field tests show that the power head capacity, high efficiency, full-featured and easy to operate, provide equipment support for efficient and safe drilling.
