Embodiment

[0104] 1. Overall device design and composition

[0105] The on-orbit assembly device of the present invention for large-length antennas includes: a support frame 7, a one-way transmission mechanism, a two-way transmission mechanism, and assembly components. A certain number of space-based radar board units 8 are directly stacked, their movement in the horizontal direction is restricted by the limit guide rail 9, and they are fixed by the fixing cable 10 before the overall operation of the device. All the other parts are directly fixed on the support frame 7, such as figure 1 shown.

[0106] 2. Design of space-based radar board unit

[0107] The space-based radar board unit 8 is made up of a board main body 12 , a limit block 13 and a limit block 14 . The board main body 12 is processed with a quick-connect screw mounting hole a, a convex strip b, a positioning cone column c, and an iron sheet groove d. Such as figure 2 .

[0108] The limit block 13 and the limit block ...

Abstract

The invention discloses a large-length antenna-oriented containerized storage type on-orbit assembling device and method. A one-way conveying mechanism, a two-way conveying mechanism and an assemblingassembly are fixedly mounted on a supporting frame; each space-based radar board unit is fixedly connected with a one-way conveying mechanism, the one-way conveying mechanisms drive the multiple space-based radar board units to move synchronously, and limiting structures matched with the space-based radar board units are arranged on the one-way conveying mechanisms to limit torsion and shaking ofthe space-based radar board units. The bidirectional conveying mechanism drives the space-based radar board units located at the bottom of the stacked structure to be coplanar with the last but one space-based radar board unit located at the bottom of the stacked structure, or drives the multiple space-based radar board units formed through splicing to move in the opposite direction of the splicing direction. The assembling assembly is used for splicing and fixing the space-based radar board unit located at the bottom of the laminated structure and the last but one space-based radar board unit located at the bottom of the laminated structure into an integral plane structure. The method has the characteristics of simple system composition, expandability, high realizability and the like.

Description

technical field [0001] The invention relates to a container-type on-orbit assembly device and method for large-length antennas, and belongs to the technical field of antenna on-orbit assembly. Background technique [0002] Space-based radar has received extensive attention from many countries due to its ability to cover the world and not be affected by geographical, political, strategic and other factors, and to achieve all-weather, day and night continuous monitoring and many other advantages. [0003] However, due to the influence of rocket thrust, fairing envelope and mechanism complexity, the current deployment mechanism is difficult to meet the construction requirements of large-area and long-span space structures required by future deep space exploration, astronomical observation, space-based radar and other projects. [0004] On-orbit assembly is to sequentially assemble basic units such as structural modules and functional modules into the desired large-scale space s...
