Abstract
The invention relates to a trolley traveling freely on an arched orbit with strong ramp adaptive capability, and the trolley is particularly applied to a switching supporting system for a retractable roof in a large stadium, thereby realizing a retractable roof. The trolley consists of a connecting base, a cartwheel, a bogie frame, an inverted hook, a cross coupling block, and a horizontal guide wheel, etc. The trolley has compact and reasonable structure and large load bearing. Wheel centers of various wheels of the trolley can be not coplanar; when in traveling, various wheels can automatically adjust the height thereof according to different positions, thereby making up for the defect that the prior trolley is influenced by the different orbit height, meanwhile ensuring balanced load bearing for various cartwheels. The trolley has the function of automatically compensating expansion and contraction of roofing. The trolley is provided with a horizontal guide pulley, which can prevent the trolley from deviating the orbit or biting rail. In addition, considering larger roofing area and more powerful overturning force under strong wind, in order to guarantee safety, the inverted hook is arranged under the trolley frame, the inverted hook can clamp at two sides of the orbit, thereby preventing the roofing from overturning.
