A space load locking device

Abstract

The invention discloses a space load locking device, comprising: a supporting cylinder, a clamping mechanism arranged in the supporting cylinder, a pressing mechanism and a pre-tightening mechanism, the supporting cylinder includes an upper cylinder body and a lower cylinder body; The radial movable setting of the support cylinder; under the action of the pre-tightening force of the pre-tightening mechanism, the pressing mechanism pushes the clamping mechanism to move, so that both the upper cylinder and the lower cylinder are engaged with the clamping mechanism; the pre-tensioning is released According to the pre-tightening force of the mechanism, the clamping mechanism moves toward the direction close to the central axis of the upper cylinder, so that both the upper cylinder and the lower cylinder are released from the clamping connection with the clamping mechanism. The space load locking device provided by the present invention effectively utilizes the space inside the support cylinder, so that the structural layout of the space load locking device is more compact and reasonable; The force is released, which makes the operation process convenient, avoids the situation that multiple locking mechanisms are used together, and improves reliability.

Description

technical field [0001] The invention relates to the field of aerospace technology, more specifically, to a space load locking device. Background technique [0002] During the launch of space payloads such as large and medium-sized aerospace cameras, it is necessary to use a temporary support device to connect the space payload to the satellite platform to protect it from entering the working orbit without damage; Open, remove the hard connection of the satellite platform, and replace it with an isolation device, so as to ensure the quality of optical imaging. [0003] In the launch of the spacecraft, the currently commonly used locking and unlocking devices mainly include a tape spring type star-rocket connection and separation device and a multi-point tape unlocking support. [0004] The tape spring type star-arrow connection and separation device mainly uses two flexible half-circle tapes to wind up multiple discrete blocks that are in contact with the connected body.

Problems solved by technology

After the two straps are unlocked and separated, they need to further occupy the external space of the support, which makes it difficult to realize the layout design when the connection space is tight; considering the symmetry of the preload, each set of unlocked supports requires 2 or 4 explosive bolts, all of them need to be exploded to be unlocked, which requires high reliability
