Description

A protective compartment for a tunnel boring machine cutter head monitoring vision system Technical Field

[0001] This utility model belongs to the technical field of tunnel excavation equipment. Under the situation of intelligent tunnel excavation equipment, in the process of developing a visual system for recognizing cutter wear and surrounding rock conditions, a protective compartment for storing the cutter visual monitoring system in the retracted state is designed. Background Technology

[0002] TBMs operate in extreme environments with long distances and great depths, where geological conditions are extremely complex. To improve the efficiency of cutterhead inspection, monitor tunneling progress in real time, and provide timely warnings, it is essential to design and build an industrial machine vision system based on a 3D binocular vision camera to measure cutterhead wear and monitor the tunnel face in front of the cutterhead in real time. During tunneling, the cutting machine often accumulates large amounts of mud and dust as it works with components such as the cutters. This contamination not only affects the normal operation of the equipment but also accelerates wear. TBMs frequently encounter alternating layers of soft and hard strata during actual excavation, resulting in complex geological conditions, intense vibrations, and heavy impacts. Therefore, a protective chamber is needed for the cutterhead wear recognition vision system to effectively protect, clean, and dry the equipment, ensuring its normal operation in harsh working environments. Summary of the Invention

[0003] The purpose of this invention is to provide a protective compartment for a tunnel boring machine cutter head monitoring vision system. This compartment reduces external interference to the system and allows for cleaning and drying of the internal components. It effectively prevents direct impacts from the external environment, such as water, dust, and chemicals, extending the system's lifespan and preventing damage from accidental collisions or impacts, thus ensuring the system's normal operation.
