Description

Shield constructs wireless warm-pressing and detects cutter system

Technical Field

The utility model relates to a tunnel boring machine cutter monitoring technology field specifically is a shield constructs wireless warm-pressing and detects cutter system.

Background

In the shield construction process, a cutter head cutter is an essential tool, a cutter, a scraper, a hob, a pilot cutter and other cutters are arranged on a cutter head, tunneling is performed in a stratum with high strength grade, the hob is one of the most important cutters, and the impact resistance and 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 current methods for detecting the abrasion of the cutter head and the cutter comprise 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 hob changing operator, the detection methods can only be judged by a 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 is used as a sensor and a device for detecting the wear of a cutter of a shield machine, and a cutter system is a detection device for detecting the wear of the cutter, wherein the detection device consists of a trapezoidal capacitor network;

patent 201811129130.X discloses a pressure type shield cutter head cutter wear detection device and an application method thereof, and the principle is that a pressure and temperature integrated sensor is installed at a part to be detected of a cutter head cutter rotation track, and the pressure and 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;

the patent 201320505325.6 shield cutter head cutter wear detection device is characterized in that 5 groups of pressure test points are arranged on a cutter head rotation point, and the cutter wear condition is judged by 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 used as a main mode, when the pressure-maintaining tunneling process is encountered in a complex and variable stratum, the situation that the cutter breaks the stratum surrounding rock 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 difficult to judge. If the cutter head cutter needs to be inspected, the cutter head cutter needs to 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 inspect the cutter, so that not only is a large amount 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.
