Abstract

Abstract:

To improve the accuracy of the selfdeveloped robot in assembly of prefabricated arc parts, a Tshaped triple prism fine adjusting method is designed. Three fine adjusting schemes for prefabricated arc parts are introduced, and their improving principles are displayed. The selfdeveloped robot realizes intelligent assembly of prefabricated arc parts with a low labor consumption and safe operation. A assemble precision of 3 mm for prefabricated arc parts is achieved through continuous improvement.

Key words: largediameter shield, railway tunnel, arc part prefabrication and assembly technology, intelligent construction, fine adjusting method
