Foldable spheroid prop structure for large-scale performances

Abstract

The invention discloses a foldable spheroid prop structure for large-scale performances, which comprises a spheroid (3), an elevating device (1), a bottom layer fixing frame (9) and a self-prestressed steel cable. The spheroid (3) can be folded; the elevating device (1) is arranged inside the spheroid (3), and the top part of the elevating device (1) is connected with the top part of the spheroid; the bottom layer fixing frame (9) is used for laying and fixing the elevating device (1); self-prestressed steel cable is arranged in the spheroid (3) and used for maintaining the stability of the spheroid (3) which is in extending state. Before or after performances, the prop structure can be folded to be stored in a space, the volume of which is smaller than half of the spheroid. The prop structure can be unfolded to be a large spheroid during the performance, and the spheroid can bear the load of the spheroid and a plurality of stunt performers and simultaneously maintain the stability of the spheroid.

Description

technical field [0001] The invention relates to a stage device, in particular to a retractable and expandable performance prop structure capable of carrying performers. Background technique [0002] In large-scale performances, some large structures or props often need to be made into spherical bodies with a height of more than 10m, and stuntmen are required to perform stunts on the spherical bodies. The existing spheroid performance props not only take up too much space, but also prevent stuntmen from getting in place quickly. In addition, since the existing spherical performance props cannot be contracted, the required storage space is relatively large. [0003] At present, there is no spheroid performance prop that can be stored in a relatively small space and can meet the load-bearing requirements of the spheroid itself. [0004] In addition, for the prop structure of the above-mentioned spherical body, since many performers need to perform performance activities such ...
