带有预紧功能的新型钻杆夹持器的研究

〗Research on a Drill Pipe Holder with Preload Function

摘要:

〗在分析现有机械式钻杆夹持器的问题基础上，针对解决机械钻杆夹持器的工作可靠性、操作性问题，选用铰链式的增力夹持结构，设计了一种带有预紧夹持功能的夹持器，增加了卡瓦的初始夹持力，改善了夹持器的工作性能。

Abstract:

Based on the analysis on the problems of existing mechanical drill pipe holder, in view of the mechanical drill pipe holder’s working reliability and operability, the hinged force-increasing clamping structure is adopted to design a kind of holder with preloaded clamping function, which c52an increase the initial clamping force of gripper and improve the performance of drill pipe holder.
