【摘要】 对深孔钻削过程中出现扭矩增大及折断钻头钻杆问题进行了分析,介绍了一种钻杆主轴与电机轴的连接中安装扭矩传感器,进给系统的传动链中安装电磁离合器的深孔钻削安全保护与控制技术.当扭矩增大时,可以快速检测扭矩参数,并控制离合器迅速脱开,停止进给,保护钻头钻杆.更多还原

【Abstract】 The problem of torque increase and drill fracture during the process of deep well drilling was analyzed,and a safety protection and control technique was introduced,where a torque sensor was fixed between drilling bar and motor axis,while an electromagnetic clutch was fixed in the transmission chain of feed system.When the torque was being increased,this equipment would quickly measure the data of torque,making electromagnetic clutch opened and feed stopped,so that the driller and drilling bar would be protected.更多还原
