Expanding device of radial expandable ribbed plate mechanism

Abstract

The invention discloses an expanding device of a radial expandable ribbed plate mechanism, belonging to the expanding field of the radial expandable mechanism and solving the problems that a mast in an inflatable ring type expanding device of the conventional radial expandable ribbed plate mechanism is extremely long, needs to occupy a large space and is inconvenient to use and meanwhile the mast and a pull line can be easily intertwined to cause great potential hazard. The device comprises an inflatable ring and a plurality of mast mechanisms, wherein all the mast mechanisms comprise main masts, buckles and pull ropes; the two ends of the buckles are fixedly arranged at the two ends of the main masts; the inflatable ring is sleeved between the buckles and the main masts; the device also comprises a first secondary mast and a first thin film; one end of the main mast is fixedly connected with one ends of the two first pull ropes; the other ends of the two first pull ropes are fixedly arranged at the upper and lower ends of the first secondary masts respectively; one ends of a plurality of second pull ropes are fixedly arranged at the upper and lower ends of the first secondary mast respectively; and the pull ropes are straightened and are adhered to the first thin film. The expanding device is used for expanding the radial expandable ribbed plate mechanism.

Description

technical field [0001] The invention relates to a deployment device, in particular to a deployment device with a radially expandable mechanism. Background technique [0002] At present, the radially expandable rib mechanism generally uses an inflatable ring to drive the free end of the rib to expand radially outward. The mechanism includes a central drum shaft and a plurality of radial ribs. One end is respectively fixed on the outer wall of the central drum shaft along the circumference of the central drum shaft. A mast is fixed at the other end of each radial rib. On multiple masts, one end of multiple stay ropes is respectively fixed on one end of multiple masts, and the other end of multiple stay ropes is fixed on the radial rib corresponding to the mast where the stay rope is located, and the radially expandable rib mechanism is on When it needs to be opened, it is only necessary to fill the inflatable ring with gas to prop up the inflatable ring, and the inflatable ri...

AI Technical Summary

Problems solved by technology

[0004] The present invention solves the problem that the mast in the inflatable ring type expansion device of the existing radially expandable rib mechanism is very long and needs to occupy a large space, which is very inconvenient to use. Being entangled together will affect the expansion of the ribs, and there is a big hidden danger
