Abstract
The invention discloses a radial rib locating device of a radial-rib inflatable and unfolding antenna, and belongs to the technical field of inflatable antennas. The problems that in the process of assembling radial ribs, the situation that the radial ribs are located inaccurately easily occurs to the current inflatable antenna, and the precision of an antenna paraboloid is influenced are solved. The radial rib locating device comprises an annular scale-division supporting plate, scaleplates and a suspension device, the annular scale-division supporting plate is provided with three layers, the three layers of the annular scale-division supporting plate are gradually enlarged from top to bottom, and every two adjacent layers of the annular scale-division supporting plate are vertically connected through four connecting rods. Each layer of the annular scale-division supporting plate is of a double-layer structure, and each layer in the double-layer structures is composed of two semi-annular plates. The scaleplates are arranged on the layers of the annular scale-division supporting plate respectively, and are in sliding connection with the annular scale-division supporting plate through scaleplate seats. The suspension device comprises four Z-shaped hooks, and every two opposite Z-shaped hooks are connected through a bolt. The radial rib locating device is used for locating the radial ribs in the process of assembling the inflatable antennas.
Description
Technical field:
