摘　　要：针对钻机不同操作系统下夹持器结构不同,分析了常闭、常开夹持器工作原理、结构特点和存在的问题,提出可转换液压夹持器结构,既能实现常开夹持器功能,也能实现常闭夹持功能,同时解决了现有夹持器中的一些安全隐患,提高了夹持器的通用性。According to the different gripper structures under different operating systems of drilling rigs,the working principle,structural characteristics and existing problems of normally closed and normally open gripper were analyzed,and a convertible hydraulic gripper structure which can not only realize the functions of normally open grippers,but also realize the functions of normally closed grippers was proposed. At the same time,some potential safety hazards in existing grippers were solved and the universality of grippers was improved.
