Description

Technical Field

[0001] This utility model relates to the technical field of tunnel boring machine cutterhead design devices, specifically a low-resistance arc surface design device for high-efficiency tunnel boring machine cutters. Background Technology

[0002] A tunnel boring machine (TBM), also known as a shield tunneling machine or full-face tunnel boring machine, is a type of tunnel boring machine that uses the shield method. The construction method of a TBM involves laying supporting segments of the tunnel while the machine is excavating. This machine is characterized by completing the tunnel excavation in one go, as it completes the entire process from excavation, advancement, and support. TBMs can be classified into open-face, mechanical cutting, grid, and extrusion types according to their excavation methods.

[0003] The cutterhead is a crucial component of the tunnel boring machine (TBM). To reduce working resistance and wear, it is necessary to design the cutterhead with an arc surface. However, current TBM cutterhead arc surface design devices are inconvenient for resistance testing, reducing the efficiency of TBM cutterhead design. Therefore, we propose a high-efficiency, low-resistance arc surface design device for TBM cutters to solve the above problems. Utility Model Content
