Tunnel boring machine
First Claim
1. A tunnel boring machine comprising:
- a main body, the main body being a non-rotating body;
a cutter head that is disposed in front of the main body and is rotatable with respect to the main body;
a plurality of disc cutters rotatably mounted on the cutter head, each of the disc cutters including a cutter ring that is exposed to a front surface of the cutter head while exposed to a back surface of the cutter head, the cutter ring including a cutting edge part;
an acquisition unit that is attached to the main body behind the cutter head and disposed behind the plurality of disc cutters to acquire cutting edge position data indicating a position of the cutting edge part of one of the disc cutters;
a discrimination unit for discriminating which one of the plurality of disc cutters is the disc cutter for which the cutting edge position data is acquired by the acquisition unit; and
a calculator for calculating a wear amount of the cutting edge part of the disc cutter discriminated by the discrimination unit based on the cutting edge position data acquired for the disc cutter.

Abstract
Provided is a tunnel boring machine that can detect a wear condition of a disc cutter with a highly reliable configuration. The tunnel boring machine includes a measurement device. The measurement device is disposed behind the disc cutter mounted on a cutter head. The measurement device has a function as an acquisition unit that acquires cutting edge position data indicating a position of a cutting edge part of a cutter ring in the disc cutter. The tunnel boring machine further includes a DC discrimination unit that discriminates which one of a plurality of disc cutters is the disc cutter the cutting edge position data of which is acquired by the measurement device and a wear amount calculator that calculates a wear amount of the cutting edge part of the discriminated disc cutter.
