AI Technical Summary
In traditional tunnel construction, the installation efficiency of steel arch frames is low, the convenience and safety of personnel operation are poor, it is difficult to achieve efficient installation of multiple precast arch frame segments, and the on-site welding process is time-consuming.
The machine uses a double-arm tunnel arch frame, which includes a platform, a longitudinal drive assembly, and a robotic arm assembly. The robotic arm assembly consists of two sets of robotic arms arranged laterally, equipped with a flipping mechanism and a pulling mechanism. Through longitudinal movement and flipping, it can achieve the orderly hoisting and installation of multiple arch frame sections. The welding process is carried out in advance, reducing the need for on-site welding.
It improved installation efficiency, shortened the single-cycle installation time, reduced the time personnel were exposed under the rock strata, reduced safety risks, and enabled the safe and efficient installation of precast arch frame segments.
