摘　　要：冲扣钳作为铁钻工的一部分,是用来完成紧扣和冲扣的动作,与旋扣钳配合能快速地完成钻具上卸扣作业。该文在介绍冲扣钳结构原理的基础上,重点对冲扣钳结构进行了设计,确定了冲扣钳夹紧结构、冲扣结构,以及液压控制系统等关键技术。配套该冲扣钳的铁钻工目前已多套应用于现场,试验表明,该装置结构安全可靠,可实现远程控制,提高了现场作业的安全性。As a part of the iron roughneck, the torque wrench used for make-up and break-out, working with the spin can make up or break out drill collar connections. On the basis of introducing the structure principle of the torque wrench , this paper designs the structure and determines the key technologies such as clamping mechanism and the punching mechanism and hydraulic control system. Supporting the torque wrench of the iron roughneck is which has been applied in the field,many tests show that the structure of the device is safe and reliable,and can be controlled remotely,which improves the safety of the field operation.
