Automatic cruise-based cutter life prediction system and prediction method thereof

Abstract

The invention discloses an automatic cruise-based cutter life prediction system and a prediction method thereof. The system comprises an industrial computer of a shield tunneling machine; a tool wear sensing device; and a ground control center server; the ground control center server comprises an online cutter wear monitoring module, a data storage processing module, a visual display module and a cutter life prediction module; when an on-line cutter monitoring module in a data storage processing module monitors that the actually measured cutter abrasion loss reaches 85% of the maximum value of the cutter abrasion loss, the cutter life prediction module automatically calls hydrogeological data and surrounding environment condition data in a tunneling three-dimensional entity model established in the data storage processing module, and shield tunneling machine position related data to judge and select a proper cutter maintenance and replacement place and mileage within a tunneling distance range of the shield tunneling machine. A large amount of manual study and judgment is avoided, time and labor are saved, the informatization and intelligence degree is high, timeliness is high, the tool can be overhauled and replaced in time, and the situation that the construction progress is affected due to tool abrasion is avoided.

Description

Technical field [0001] The present invention relates to the field of shield construction, which specifically belongs to the automatic cruising tool life prediction system and its prediction method. Background technique [0002] With the rapid development of rail transit, the shield method has gradually become the main construction method of the tunnel of the subway section due to its construction speed, short period of time, short cycle, high safety, high automation. The shield method is mainly the cutting tunnel of the cutter cutting soil, so the problem of shield cutter tool wear is an irreversible problem. It must be repaired by the cutter tool when it is necessary, and it must be replaced when it is severe. Where is the shield cutter tool to be repaired, then a constant tracking monitoring of the overall wear of the cutter disk is required. At present, there are three main methods, which are hydraulic, electromagnetic or ultrasonic wavelengths to monitor the tool cutter wear,...
