Description

Background

In the shield construction process, a cutter head cutter is an indispensable tool, a cutter, a scraper, a hob, a pilot cutter and other cutters are arranged on a cutter head, the tunnel is tunneled in a stratum with high strength grade, the hob is one of the most important cutters, and the shock resistance and the cutting capability are strong. With high load and long-time use, the hob ring is worn to become the most common fault, and the hob is more seriously even has the problems of eccentric wear, falling off and the like. The existing method for detecting the abrasion of the cutter head and the cutter comprises the following steps: a normal pressure and pressure warehouse entry detection method, a data analysis method, a cutter head abrasion detection alarm method and the like. However, the detection methods cannot visually detect each worn hob, and for a tool changing operator, the detection methods can only be judged by a tool measuring ruler or experience, and for special conditions, the detection methods can only be completely replaced, so that the economic cost and time are greatly increased, and a lot of adverse effects are brought to shield construction.

Patent 201511023637.3 discloses a sensor, a device and a cutter system for detecting wear of a cutter of a shield tunneling machine, wherein the cutter system is a device for detecting the wear of the cutter, and the device consists of a trapezoidal capacitor network;

patent 201811129130.X discloses a pressure type shield cutter head cutter abrasion detection device and an application method thereof, and the principle is that a pressure and temperature integrated sensor is arranged on a part to be detected of a rotating track of a cutter head cutter, and the pressure and the temperature in a sealed cavity are detected;

patent 201510216378.X discloses a wireless detection device for the rotation speed and the abrasion of a shield hob, which is based on the principle that a wireless sensor is embedded in a cutter box of a cutter head to detect the abrasion loss and the rotation speed of a cutter;

patent 201320505325.6 shield cutterhead cutter abrasion detection device, which is based on the principle that 5 groups of pressure test points are arranged on a cutterhead rotation point, and cutter abrasion is judged according to pressure leakage or lower than 60 bar;

in different stratums, the tunneling modes of the shield tunneling machine are different, mainly pressure-maintaining tunneling is taken as a main mode, when complex and variable stratums are encountered in the pressure-maintaining tunneling process, the situation that the stratum surrounding rocks are crushed by the cutter is difficult to judge through shield tunneling parameters, and whether the shield cutter has images such as abrasion, eccentric wear, cracking and the like is also difficult to judge. If the cutter head cutter needs to be checked, the cutter head cutter must be stopped at a specified position or a protected position, for example, a reinforced area or a stratum with good stratum stability is stopped and a warehouse is opened to check the cutter, so that not only is a great deal of preparation in the early stage required, but also the efficiency and the progress of the whole construction are influenced. The tool repairing area for the maintainers is an unsupported area, if the tool is repaired after being stopped for a long time, the uncertain factors are large, and in addition, the tool loss cost can also be increased due to the fact that the tool is clearly abraded.
