摘要
为了提高煤矿井下坚硬岩层钻孔的施工效率,解决坚硬岩层钻孔技术难题,研制出ZYW-4000G高转速钻机,其具有切削转速高、输出转矩大、钻进能力强等特点。介绍了该钻机的整体结构特点及其双马达动力头传动系统、液压系统、钻孔姿态调节系统等关键技术。通过在坚硬岩层中的钻孔试验及顺煤层中的钻孔试验表明,该钻机结构合理、操作方便、系统发热量小。该钻机与相关钻具配合,在坚硬岩层中及在顺煤层中钻孔时,其钻孔效率远高于普通钻机。
In order to improve the drilling efficiency in hard stratum in coal mines and solve the technical problem of borehole drilling in hard stratum,Model ZYW-4000 G high-speed drilling machine was developed,which has the features of high drilling speed,large output torque,strong drilling ability and so on. This paper described the overall structure of this drilling machine and its key technologies,including the double-motor power head driving system,the hydraulic system and the adjusting system for the drilling posture. The drilling tests both in the hard stratum and coal seam indicated that this drilling machine was rational in structure and easy to operate and had a little heating. When this drilling machine is used with the relevant drilling tools to drill holes in the hard stratum and coal seam,its drilling efficiency is much higher than that of the ordinary drilling machines.
