Friction device for external rail of rotary platform

Abstract

The invention relates to a friction device for an external rail of a rotary platform. The friction device comprises a rotary platform skeleton, an annular internal rail, an annular external rail and an inner supporting wheel set, wherein the internal rail and the external rail are fixedly connected with the lower surface of the rotary platform skeleton; the inner supporting wheel set is jointed with the lower surface of the internal rail and is anchored on a ground foundation; the friction device is characterized in that the lower surface of the external rail is jointed with a plurality of centripetal supporting wheel sets which are anchored on the ground foundation; and the external rail is connected with a frictional driving mechanism through two side walls of a web. In the friction device for the external rail of the rotary platform provided by the invention, the rotary platform is driven to rotate by the frictional driving mechanism; the structure of the friction device is more simple and reasonable than the traditional structure; two supporting wheels of the centripetal supporting wheel sets are mounted in a form of an inclined angle along radial direction; the centripetal degree of the supporting wheels is ensured; a biased error of the rotation of the rotary platform around a rotating center is smaller; and the rotary platform is more stable during the rotating process.

Description

technical field [0001] The invention relates to a rotating device, in particular to a friction device for an outer rail of a rotating platform used for a rotating stage of a rotating restaurant. Background technique [0002] In order to meet the needs of the tourism industry, many high-rise buildings are equipped with revolving restaurants, revolving stages and other sightseeing facilities on the top. These facilities generally adopt a revolving platform structure. The rotating platform in the prior art is driven by the gear on the output shaft of the motor to rotate the platform. The structure in which the gear drives the ring rack to rotate is complex in design and high in manufacturing cost. In addition, transmission parts such as gears and ring racks are not easy to repair after wear or damage, and the repair cost is also high. In the traditional structure, each support wheel in the outer rail support wheel set of the rotating platform only supports the rotating platfor...
