Description

Technical Field

[0001] This utility model relates to the field of lining trolley rail handling technology, and in particular to a tunnel lining trolley rail handling device. Background Technology

[0002] As a core piece of equipment in the secondary lining construction of tunnels, the efficiency of the rail transport system of the tunnel lining trolley directly affects the construction progress. In the secondary lining construction of tunnels, due to the narrow working environment, the traditional rail handling relies heavily on manual labor, resulting in low handling efficiency and safety hazards.

[0003] To address this technical bottleneck, publication number CN209908537U proposed a dedicated handling device that innovatively integrates three functional modules: transportation, hoisting, and clamping. The transportation device uses a support plate and roller structure for mobile transport, the hoisting device uses a traction rope for vertical lifting, and the clamping device positions the rails. While this solution theoretically solves the problem of low efficiency in manual handling, significant structural design flaws have been found in practical applications: the second support groove uses an extended protruding structure, which can easily cause interference with other equipment within the tunnel, especially in hydraulic tunnels with a typical horseshoe-shaped cross-section. To address these shortcomings, we propose a tunnel lining trolley rail handling device. Utility Model Content
