Description

Technical Field

[0001] The present invention relates to the technical field of shield construction, and in particular to a shield cloud platform multi-line center cutter damage early warning system. Background Art

[0002] The shield cloud platform is a remote system for real-time collection and management of shield construction data. With the rapid development of computers and computer networks, the shield cloud platform can remotely collect and grasp the detailed information of multiple construction lines in real time, and can quickly manage multiple lines and discover fault information in a timely manner, solving the problem of difficult management of shield construction lines in multiple regions.

[0003] As far as the center cutter damage failure in shield construction is concerned, the cutter head center cutter damage accidents occur frequently, are difficult to detect and have great harm. It is generally believed that the cutter head center cutter wears to a certain extent or the center cutter breaks or twists, resulting in abnormal excavation events, which are all center cutter damage failures. When the center cutter is damaged to a certain extent, it will cause abnormal excavation, reduced penetration, severe wear of the cutter head tools, excessive energy consumption and other problems before it is discovered. Minor center cutter damage will cause severe wear of other tools on the cutter head during excavation, increased pressure in the propulsion cylinder, slow excavation process, increased energy consumption, severe heat generation, and easy to induce other engineering accidents.

[0004] Traditional detection of center cutter damage is still mainly based on the experience of the shield machine operator, or the auxiliary tool wear detection oil pressure sensor. However, the handling of the face area is complex, the sensors are easily damaged, and the number of sensors installed is often limited, resulting in poor sensor detection effect. The judgment of center cutter damage is still mainly based on manual judgment, which is often made when an accident occurs or a serious abnormality occurs during excavation. Therefore, rapid and accurate assessment and early warning of center cutter damage are urgent needs for shield construction.

[0005] In order to effectively solve the problem that the center cutter damage is difficult to detect during shield construction, a multi-line center cutter damage early warning system for the shield cloud platform is designed, which can realize the simultaneous assessment and early warning of the shield center cutter damage status of multiple lines.
