Problems solved by technology
In this patent, although the measurement error caused by the unnecessary increase in bending moment is overcome, because the strain resistance gauge is difficult to be well combined with the column beam, the solder joint of the strain resistance gauge is easy to fall off, and the calibration steps are complicated in the early stage, the solution exists. Disadvantages such as short service life, easy damage, and complicated operation

The invention discloses a three-way force measuring structure of a composite hob. The three-way force measuring structure comprises a large cutter box assembly, a composite force measuring sensor assembly, a small cutter box assembly and a hob assembly, the small knife box assembly is mounted in the large knife box body through two three-component force sensors; and the two three-component force sensors and the three groups of fiber grating sensors arranged on the box body of the small knife box form a composite force measurement sensor assembly which is used for accurately measuring the vertical force, the rolling force and the lateral force of the hob.
Description
technical field [0001] The invention relates to a hob three-way force measuring structure, in particular to a composite hob three-way force measuring structure used for a hob-rock-machine interaction experiment platform. Background technique [0002] The full-face tunnel boring machine (TBM) is an advanced engineering equipment for tunnel excavation. The hob is an important tool for breaking rocks during the tunneling process of the shield machine. Its rock-breaking efficiency directly affects the tunneling speed of the shield machine. The shield machine will encounter various geological conditions and rocks of different properties during the excavation process, and the stress properties of the cutters will change drastically, which puts forward high requirements on the design of the cutters. Using the hob-rock machine interaction experimental platform to study the rock-breaking mechanism, structural form and rock-breaking mechanics prediction model of the hob can improve th...
