| 中文摘要:针对大陆科学钻探接卸钻杆进行上卸扣操作复杂繁琐、夹持稳定性差等问题，设计了一种适应于科学钻探全液压顶驱钻机的新型背钳装置。该装置具有夹持力大、对钻杆损伤小、工作性能稳定、双向浮动等特点，解决了钻进过程中频繁倒杆问题，快速完成上卸扣操作作业，极大地缩短了辅助作业时间。并利用ADAMS动力学仿真软件，对夹紧机构进行了运动仿真分析，验证了机构设计的合理性。 |

| Abstract:According to the complicated unloading operation for drill rod and the poor clamping stability, new back-up wrench device for hydraulic top drive drilling rig was designed to adapt to the Continental Scientific Drilling. This device has the advantages of large clamping force, little damage to drill rod, stable performance and two-way floating, by which the frequent rod lifting is saved and the subsidiary operation time is greatly reduced by rapid makeup and breakout operation. And using ADAMS dynamics simulation software, the motion simulation analysis is made on the clamping mechanism to verify the rationality of the mechanism design. |
