摘要
遥控维护技术和装备在核物理装置中得到广泛的研究和应用,目前已成为核物理装置中放射性部件维护不可缺少的重要手段。多层冷却管道是核物理装备重要基础设施,一般采用的多层结构,这种结构在增强管道性能的同时,也增加遥控维护条件下管道剪切的难度,对剪切工具性能也提出较高的要求。结合实际遥控维护工作中遇到的问题,改进刀刃,增加副刀刃,以克服上下刀刃间隙产生的扭转扭矩。由于老化和辐照损伤对性能的影响,管道需要进行定期的检查和更换,开展液压剪切工具的设计工作显得非常有必要。
Remote maintenance handing technology and equipments are researched and applied extensively and thoroughly in nuclear physics equipment,and play an important role in replacement of radioactive components in nuclear physics. In nuclear physics equipment,multilayered cooling pipeline is an important infrastructure which strengthens the performance of the pipeline,increases the difficulty of pipe cutting under the condition of remote maintenance handing and puts forward higher requirements to the cutting tool. Based on the problems from maintenances,two side blades are added in to overcome the torque generated by the gap between the top and the bottom edges. Due to aging and irradiation damage,pipes should be regularly inspected and replaced,and the design of hydraulic cutting tool is quite significant.
