针对某海洋钻井平台TDS系列中8SA顶驱在大修拆解中提环销轴转动、箱体提环销孔存在偏磨、扩大成椭圆型的现象，通过分析造成原因；总结顶驱箱体销孔修理前，取出提环销的办法；分析比较箱体销孔两种常规修复方法的优缺点，给出顶驱下箱体销孔的修理办法。最后，从设计角度出发，探讨性地提出从根本上消除顶驱箱体销孔偏磨的方法，并加以论证，部分方法已经投入实践运用，旨在为今后类似设备的升级改造提供借鉴意义。

In view of the phenomenon that the lifting bail pin shaft of 8SA top drive in the TDS series of an offshore drilling platform, rotates in the overhaul and dismantling, and the lifting bail pin hole of the box is eccentrically worn and expanded into an ellipse, the causes are analyzed. The advantages and disadvantages of two conventional repair methods of box pin hole are analyzed and compared, and the repair methods of lower box pin hole in top drive overhaul are given. Finally, from the perspective of design, the methods to fundamentally eliminate the eccentric wear of the pin hole of the top drive box are proposed and demonstrated. Some methods have been put into practice, aiming to provide reference for the upgrading and transformation of similar equipment in the future.
