Supporting device used for satellite antenna deployment

Abstract

The invention relates to the technical field of strut member steel structures and provides a supporting device used for satellite antenna deployment. The device comprises a supporting beam frame and a breadboard, wherein the supporting beam frame is of a rectangular frame structure, the breadboard is arranged at a position close to the rear end of the frame structure of the supporting beam frame, the breadboard is wider than the supporting beam frame and is shorter than the supporting beam frame, a plurality of lifting lugs are further arranged on the supporting beam frame, a first transverse plate, a second transverse plate and a third transverse plate are arranged at the front end of the supporting beam frame in sequence, an upper antenna connecting plate, a middle antenna connecting plate and a lower antenna connecting plate are arranged on the three transverse plates, an upper supporting rod component, a middle supporting rod component and a lower supporting rod component are arranged on the three antenna connecting plates, the upper supporting rod component is longer than the middle supporting rod component, and the middle supporting rod component is longer than the lower supporting rod component. According to the supporting device used for satellite antenna deployment, antennae and a corresponding mechanism are supported and fixed after being deployed according to specific angles, and gravity unloading is achieved.

Description

technical field [0001] The invention relates to the technical field of steel structures of supports, in particular to a support device for satellite antenna deployment. Background technique [0002] Satellite antennas are important equipment for satellites. They are used outside the satellite cabin. In order to meet the temperature requirements of the space environment, corresponding thermal control measures are required. Therefore, the antenna needs to conduct thermal vacuum and thermal balance tests on the ground to verify the correctness of the thermal control design of the antenna. performance, effectiveness, and the ability to assess the antenna's adaptability to the space environment. [0003] The antenna of each satellite has a different structure due to different functions. It is generally composed of a mechanism mounting plate, an unfolding arm, a two-dimensional pointing mechanism, and an antenna. The antenna is generally kept in a contracted state during transport...

AI Technical Summary

Problems solved by technology

At present, the antenna is generally deployed directly. After deployment, a support rod is used combined with the locking structure of the antenna itself to realize the deployment support of the antenna, but it cannot meet the requirements of gravity unloading during the deployment process, and it is easy to cause varying degrees of damage to the antenna rotation joint.

[0004] According to the needs of the satellite antenna deployment process, the traditional support device cannot meet the requirements of the antenna deployment support. At present, no description or report of similar technology has been found, and no similar information has been collected at home and abroad.
