Retractable roofs can be used independently to transform indoor and outdoor environments, and can also be used in conjunction with other institutions to form large-scale performance scenes, such as Shanghai Qizhong Tennis Center, China Tennis Center, Nantong Sports Exhibition Center, Ordos Dongsheng Stadium, Shaoxing County Sports Center. At present, retractable roofs can be divided into horizontal movable retractable roofs, rotating retractable roofs, and folding retractable roofs according to the opening and closing methods. Among them, the rotating retractable roof is the most common. This form saves more space than the horizontal movable type, and unlike the folding retractable roof, there are many restrictions on the design of the movable roof. The rotating retractable roof includes: a fixed roof, a rotating roof connected to the fixed roof through a rotating shaft; a mechanical transmission system is provided on the fixed roof, and a shaft hole is provided on the rotating roof to install the rotating shaft, and the rotating shaft is driven by the mechanical transmission system, thereby driving the rotating roof to rotate relative to the fixed roof.
