摘　　要：针对死绳固定器绳轮强度、安全裕度不足和结构失稳等安全问题,根据JZG97型万米超深井钻机死绳固定器绳轮受力及结构特点,提出采用增加腹板的方法来解决死绳固定器绳轮存在的问题。采用有限元法数值模拟,分析了不同腹板绳轮的结构力学性能,三腹板绳轮的强度、安全裕度均满足钻井作业时的安全要求,确定采用三腹板绳轮。实物测试试验中,三腹板绳轮仿真结果与试验结果的最大相对误差为12.95%,综合分析仿真结果与实验结果基本吻合;线性屈曲分析表明,最大死绳拉力作用下的三腹板绳轮临界屈曲载荷为绳轮实际受载的48.8倍,满足结构稳定性要求。研究表明,三腹板绳轮可以解决死绳固定器绳轮存在的问题,可以为万米超深井钻机结构设计提供支持。To address the safety concerns such as inadequate strength,safety margin,and structural instability of the dead line anchor rope wheel,the method of adding webs was proposed to solve existing problems of dead line anchor rope wheel according to the mechanical properties and structural characteristics of dead line anchor rope wheel for JGZ9710000-meter ultra-deep well drilling rig.With finite element numerical simulation,the structural properties of different different web rope wheels were analyzed,and the three-web rope wheel structure satisfied the safety criteria for drilling operations in terms of both strength and safety margin.The three-web rope wheel was therefore determined to be adopted.The maximum error between the simulated and the experimental results of the three-web rope wheel was 12.95%in the physical experiment,indicating a close alignment between simulation and the experimental results.Moreover,the linear buckling analysis showed that the critical buckling load of the three-web rope wheel under maximum dead line tension was 48.8 times higher than the actual load of the rope wheel,which meet the structural stability requirements.This research shows that the three-web rope wheel can solve the existing problems in dead line anchor rope wheels,providing support for the structural design of drilling rigs for 10000-meter ultra-deep wells.
