Abstract

In order to realize rapid disassembly of TBM cutter system by robot, a TBM integrated cutter system based on robot operation is proposed. According to the applicable scenarios and objects of the integrated cutter system, six performance evaluation indices are proposed and analyzed. According to the scale of 1∶4, the vibration tightening experiment is carried out on traditional cutter system and integrated cutter system. The experimental results show that the percentage of residual preload of traditional cutter decreases 2.31 times as much as that of integrated cutter system after 20 h vibration experiment with acceleration of 3g and vibration frequency of 30 Hz, which indicates that the antiloose performance of integrated cutter system is better than that of the traditional one, and the new integrated cutter system recommended can meet the TBM requirement of cutter replacement by robot.

Key words： TBM; integrated cutter system; cutter replacement by robots; antiloose performance
