- 摘要:
- 采用吊盖吊装大质量静置设备时，除了对吊盖本体强度进行核算外，还需对吊盖的双头联接螺栓进行核算。本文以某工程反应器吊装时吊盖联接螺栓的核算为例，对卧态和垂直状态两种情况下螺栓的受力进行分析计算，给出了预紧力的三种选择方法及螺栓在加载前的预紧力控制值，指出了螺栓预紧时应注意的问题。
In hoisting stationary heavy equipments using hoisting cover, both the strength of the hoisting cover and the connecting double-screw bolts have to be checked. By taking an example of checking the strength of the connecting bolts of a hoisting cover in hoisting a reactor, an analytic calculation is made to the bolts subjected to force in both the horizontal and vertical states It also describes three types of pre-screwing force selecting methods and the controlled value of pre-screwing force of the bolts before loading to make safty check. Noticeable problems in pre-screwing the bolts are also pointed out in this paper.1994,5(5): 20-23,3,4 收稿日期：1994-1-3分类号：TE682参考文献：
