Long span tunnel lining trolley

Working Principle of Tunnel Lining Trolley

The trolley adopts hydraulic transmission, which simplifies the structure of the trolley frame and reduces the weight. At the same time, Tunnel Trolley also improves the sensitivity and diversity of the structure. After analysis and comparison of various trolley frame structure plans, strength calculations, and optimization, the 9m four-door frame 12m is selected The main mast structure plan reduces the structure weight by more than 40% compared with the mechanical type, and reduces the manufacturing cost by more than 25%.

Steel mold steel mold is the operating equipment of the trolley. Its surface quality and external dimension accuracy directly determine the quality of the concrete lining. Together, it is the most difficult part to process. Reasonable processing and welding technology have been formulated, and special assembly welded tires have been planned and processed. Die to ensure the accuracy of the overall dimensions, minimize welding distortion, ensure lubrication of the surface, and no defects such as height.

In order to control the misalignment of adjacent templates, the stabilizing pins of interference cooperation are used to fix the connecting plates of adjacent templates as a whole, which effectively controls the misalignment of adjacent templates caused by the gap of the bolt holes. After successfully solving the above-mentioned problems, the quality of concrete lining is ensured.

product feature:
