高转速跨输送带螺旋钻机及其关键技术
High Rotation Speed and Crossing Conveyor Auger Drill and Its Key Technologies
摘要
Abstract
In view of the disadvantages of the low rotate speed of high torque drilling rigs and the difficult transportation of split type high rotate speed drilling rigs in soft coal seam,a crossing conveyor auger drilling rig is developed,which has high speed,long stroke and crawler aiming at the need of drilling in soft coal seam.The key technologies of high speed power head,long stroke feeding device,hoisting and lifting device and hydraulic circuit with protection function are developed,and field investigation has been done in Jincheng Wangpo Coal Mine.The industrial tests indicate that:this rig has reasonable structure,advanced hydraulic system,convenient transportation,high efficiency and the capability of drilling 200 meters in the soft coal seam.关键词
