摘要
部分核电厂采用从堆腔底部向上安装堆外核探测器的新型安装方式,但安装和更换过程中维修人员仍需进入堆腔底部的高辐射环境进行工作。因此,设计了一种在强辐照、不规则以及狭窄的堆腔内辅助安装堆外核探测器的智能机器人。该探测器辅助安装机器人可以耐受停堆后的高辐射剂量,可以在堆腔底部灵活运动,还可以将其分节运输,并到探测器井底部完成探测器的连接和安装。此外,利用SolidWorks软件对机器人的结构进行三维动态模拟,分析底盘的运动,说明机器人的关键机构和安装方式,并使用ANSYS有限元分析软件对机器人的托盘和提升支架进行静力学分析,从而验证设计的合理性。
In view of the new installation method of some nuclear power plants that install ex-core nuclear detectors from the bottom of the reactor cavity upwards,maintenance personnel are still required to enter the high-radiation environment at the bottom of the reactor cavity for installation during the installation and replacement process.Therefore,an intelligent robot is designed to assist the installation of nuclear detectors outside the reactor in the strong irradiation,irregular and narrow reactor cavity.The detector auxiliary installation robot can withstand the high radiation dose after shutdown,it can move flexibly at the bottom of the reactor cavity,and it can transport the nuclear detector in sections and go to the bottom of the detector well to complete the connection and installation of the detector.In addition,using SolidWorks software to simulate the structure of the robot in three dimensions,analyze the movement of the chassis,explain several key mechanisms and installation methods of the robot,and use ANSYS finite element analysis software to carry out static analysis on the pallet and lifting bracket of the robot,so as to verify the rationality of the design.
