Description

Technical Field

[0001] This utility model relates to the technical field of tunnel boring machine cutterhead holders, specifically a tunnel boring machine cutterhead holder installation fixture. Background Technology

[0002] The cutterhead of a tunnel boring machine (TBM) is equipped with numerous roller cutters, which are mounted on cutterhead holders. These holders are used to fix and position the roller cutters along their trajectories. Each roller cutter needs to be positioned and fixed to the cutterhead structure via its holder, and a single cutterhead typically has dozens of roller cutters. Therefore, dozens of holder positions need to be fixed on each cutterhead. Currently, the common method is to install the roller cutters on the holders and then position the holders accordingly. However, due to the heavy weight of the roller cutters, installation is time-consuming, labor-intensive, and inconvenient, reducing the efficiency of holder installation. To address these issues, this paper proposes a technological innovation based on existing TBM roller cutterhead holder installation fixtures. Utility Model Content
