Space load locking device

Abstract

The invention discloses a space load locking device which comprises a supporting cylinder, a clamping mechanism, a pressing mechanism and a pre-tightening mechanism, wherein the clamping mechanism, the pressing mechanism and the pre-tightening mechanism are arranged in the supporting cylinder;p the supporting cylinder comprises an upper cylinder body and a lower cylinder body; the clamping mechanism is movably arranged in the radial direction of the supporting 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 the upper cylinder body and the lower cylinder body are both clamped and matched with the clamping mechanism; and the pre-tightening force of the pre-tightening mechanism is released, and the clamping mechanism moves in the direction close to the central axis of the upper cylinder body, so that the upper cylinder body and the lower cylinder body are both released from clamping connection with the clamping mechanism. According to the space load locking device provided by the invention, the space in the supporting cylinder is effectively utilized, so that the structural layout of the space load locking device is more compact and reasonable; besides, when the pre-tightening force is released, only the pre-tightening force of the pre-tightening mechanism needs to be released, so that the operation process is convenient, the situation that a plurality of locking mechanisms are matched for use is avoided, and the reliability is improved.

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
