Tbm-mounted system for testing wear resistance of surrounding rock
A recently granted patent (Publication Number: US11879874B2) discloses a Tunnel Boring Machine (TBM)-mounted surrounding rock wear resistance testing system. The system comprises a fixing module, a surrounding rock polishing module, a surrounding rock wear resistance testing module, and a central control module. The movable end of the fixing module includes a connecting block with a spherical cavity, a protective box, and support legs. The system allows for testing the wear resistance of surrounding rock by polishing a test area and conducting wear resistance tests, controlled by the central control module.
Furthermore, the patent includes claims for detachable or integrally arranged modules, a testing method based on the system, and detailed mechanisms for controlling the motion and operations of the system. The system features drive mechanisms, hydraulic drive mechanisms, support beams, and testing methods involving determining a test area, aligning modules for polishing and testing, and evaluating wear resistance based on test results. The innovative design aims to enhance the efficiency and accuracy of wear resistance testing in tunnel construction, providing a comprehensive solution for evaluating the durability of surrounding rock in tunneling projects.
