为解决现有的乏燃料立式剪切机在剪切乏燃料过程中所存在的未经剪切的元件掉入溶解器、刀架滚轮磨损等一系列问题,提出一种卧式送料剪切机的翻转机构方案,使得乏燃料组件由竖直位置翻转至水平位置。这种结构以双液压缸联动举升来实现燃料组件的翻转动作,并以滚珠丝杠副机构来实现燃料组件反转后的水平横移运动。介绍了翻转机构的工作原理并确定举升机构和横移结构设计及其参数。在完成剪切机翻转机构设计后,为保证其设计合理性对卧式剪切机送料系统翻转机构关键部件的主要失效模式进行了详细可靠性分析,并建立可靠性分析模型,最后得出具体可靠性计算结果。

In order to solve the series of problems such as the non-shearing elements falling into dissolver and cutter wheel wear when the existing spent fuel vertical shearing machine cut the spent fuel,the flip-flop mechanism scheme of a horizontal type for feeding and cutting machine which allows the spent fuel assembly to be turned from the upright position to the horizontal position is put forward.The mechanism is actuated by double hydraulic cylinders to effect the flip-flop of the fuel assembly and the horizontal traverse movement after the fuel assembly reversal by ball screw accessory mechanism...
