Design and Application of the Drag Trolley System for the Arch Corrugated Steel Plate Movable Roof

This paper conducts an in-depth discussion on the drag trolley system of the arch corrugated steel plate movable roof. Starting from the design background, it elaborates on the design scheme of the trolley drive system, the design of key components and the mechanical analysis, and also introduces the control strategy. Combined with practical engineering cases, the effectiveness and feasibility of the system are verified. The research shows that in an open-air environment, this trolley system can smoothly and synchronously drag the roof, meeting the functional requirements of the building. This scheme provides useful references for similar projects.
