摘　　要：反应堆压力容器检查机的主立柱部套是检查机于容器轴向定位和用于超声视频检查的关键部套,其运动的精准性对反应堆压力容器检查机的定位精度和可靠性具有重要影响。对实际制造装配进行研究,并通过理论计算,分析并确认了主立柱运动不同步的两个关键原因,最后通过装配工艺的改进,完成了主立柱伸缩管三组钢丝绳于水平状态下的预紧力及各端调节螺纹长度的调试,调试完成后经测试能够满足竖直状态下主立柱各级伸缩管同步运动的设计要求,精度满足使用要求。The mast, which is the main component of the Reactor pressure vessel inspection equipment（TIME[3]）, is used for axial positioning and ultrasonic ＆ C.C.T.V inspection. The accurate movement of the mast has a great influence on the positio- ning accuracy and reliability of TIME. According to the actual manufacturing and assembly, combined with the theoretical ca- lculation and, analyzed and confirmed the two key reasons for movement out of sync, finally with the assembly technique improvement, the preload and the length of the three sets of steel wire-ropes are completely adjusted under the horizontal st- ate. After the test, the mast can both meet the needs of design and usage under the vertical state.
