The load distribution laws of disc cutter on different
positions of cutterhead of fullface rock tunnel boring(TBM) machine
are of great significance to preventing the TBM disc cutter and cutter seat
from frequent overload failure. First, by upgrading the TBM boring modal
experiment platform, the load monitoring system is developed for single disc
cutter, and the direct acquisition of disc cutters with different types such as
singleedged, center doubleedged,
etc. is realized. Second, the disc cutter load and rotation speed monitoring
system is developed to realize realtime acquisition
and wireless transmission of disc cutter load and rotation speed data. Third, a
multifunctional cutterhead with adjustable disc cutter with different
specifications, adjustable cutter spacing and height differences has been
manufactured, which realizes the arrangement of disc cutter in various ways.
The upgrading of TBM boring modal experiment platform can provide experimental
tools for the theoretical rock breaking study of load distribution laws of disc
cutter and arrangement of TBM cuterhead and cutter, and as well provide a new
method for realtime monitoring of TBM disc cutter
loads.
