摘　　要：针对油气管道应急抢险使用管道手动开孔机开孔时发生卡钻,导致电机机身反向旋转的问题,采用机械设计的方法设计了管道手动开孔机卡钻泄力装置,其由传动机构、阻尼机构、差速机构组成。在管道开孔机正常作业的情况下,电机扭矩通过传动机构正常传递给开孔钻,当开孔钻切削管壁发生卡钻时,电机扭矩通过传动机构和差速机构传递给阻尼机构,并克服阻尼机构旋转做功使扭矩得到释放。开孔试验表明:该装置可以有效避免管道手动开孔机电机反转伤人,提高管道抢险作业的安全性,保护操作人员的人身安全。When a manual pipe tapping machine is used for the tapping during the emergency rescue of oil and gas pipelines, sticking occurs and leads to the reverse rotation of electrical motor. To solve this problem, a force release device for the sticking of manual pipe tapping machine was mechanically designed in this paper. This device is composed of drive mechanism, damping mechanism and differential mechanism. When the pipe tapping machine is in normal operation, the torque of electrical motor is transferred to the tapping bit through the drive mechanism. In the case of sticking while the tapping bit is cutting the pipe wall, the torque of electrical motor is transferred to the damping mechanism through drive mechanism and differential mechanism to overcome the rotation work of damping mechanism and release the torque. It is shown from tapping tests that this device can prevent effectively the personal injury caused by the reverse rotation of manual pipe tapping machine, improve the safety of pipeline rescue operation and protect the personal safety of operating personnel.
