Research on large-bolts disassembling and reassembling or remote handing maintenance

摘要

Nuclear devices are associated with the research and application of high-energy physics, and remote handing maintenance (RHM) technology is an important and indispensable tool for maintaining radioactive parts for large-scale scientific facilities. Bolts disassembling and reassembling are necessary steps to RHM. Based on the RHM demands of the Moderation in CSNS, Experiments about large-bolts were conducted in test platform. By comparing the test results of different structure design of air wrench, head of large-bolt and depth of sleeve, significant conclusions were obtained for large-bolts disassembling and reassembling, which provide a basis for auxiliary tooling development for RHM.
