Peripheral type pressing and locking device of large-sized space unfolding structure and pressing method of peripheral type pressing and locking device

Abstract

The invention provides a peripheral type pressing and locking device of a large-sized space unfolding structure. The peripheral type pressing and locking device comprises a box body, a worm fixed on one side of the box body, a worm wheel which is meshed with the worm and is connected with the box body through a worm wheel rotating shaft, a pressing and locking hook, one end of which is connected with the box body to enable the pressing and locking hook to rotate in the box body, the other end of which is provided with a sliding chute, and the tail end of which acts on a pressing point, and a swing rod, wherein one end of the swing rod is fixedly connected with the worm wheel rotating shaft and the other end of the swing rod is connected with the sliding chute of the pressing and locking hook in a sliding manner. The invention further provides a pressing method of the peripheral type pressing and locking device of the large-sized space unfolding structure. The peripheral type pressing and locking device provided by the invention is mounted and fixed at the periphery of a folded array plane to enable an unfolding mechanism to be of a compact and reliable structure in a launching stage, and can avoid the effective working surface of the array plane; and the peripheral type pressing and locking device is simple in mechanical structure and easy to operate.

Description

technical field [0001] The invention relates to the technical field of space exploration, in particular to a peripheral compression locking device and a compression method for a large space unfolding structure. Background technique [0002] In the field of aerospace early warning and resource detection, in order to improve the technical indicators such as antenna observation resolution and observation range, the size of the antenna array is required to be larger and larger. However, the payload size of the launch vehicle is limited, and the large-size antenna structure adopts the unfolded type. Before launch, it shrinks into a compact shape, and after entering orbit, it expands into a working state shape structure to achieve a large storage ratio. Therefore, it is required that the deployment mechanism can have a compact and reliable structure during the launch phase, and it has undergone the mechanical environment assessment during the launch phase. After entering orbit, ...
