Abstract

The invention relates to a repeated locking and releasing mechanism, in particular to an on-orbit repeated locking and releasing mechanism for space, and aims to solve the problem of repeated on-orbit locking and releasing of a large-scale actual load in a spacecraft. The on-orbit repeated locking and releasing mechanism comprises a trunnion locking mechanism, a lock hook compacting mechanism, a base locking mechanism, a crank and rocker mechanism and a driving gear mechanism, wherein the trunnion locking mechanism is arranged at the upper end of the base locking mechanism; and the driving gear mechanism is connected with the lock hook compacting mechanism and the crank and rocker mechanism. According to the on-orbit repeated locking and releasing mechanism disclosed by the invention, the trunnion locking mechanism, the lock hook compacting mechanism, the base locking mechanism, the crank and rocker mechanism and the driving gear mechanism are arranged in a crossed manner, so that the on-orbit repeated locking and releasing mechanism is simple and compact in structure; all the freedom degrees of a fixed object can be completely limited, and repeated locking can be realized; the maneuverability is good, so that the using requirement of on-orbit locking-releasing-relocking can be met. The on-orbit repeated locking and releasing mechanism disclosed by the invention is suitable for the technical field of aerospace and the technical field of electromechanical integration.

Description

technical field [0001] The invention relates to a repetitive locking and releasing mechanism, in particular to a space-on-rail repetitive locking and releasing mechanism. Background technique [0002] In the field of aerospace, pyrotechnic devices such as explosive bolts and pyrotechnic cutters are mostly used for the connection and separation of spacecraft and payloads. Although they have the characteristics of simple structure and high reliability, they cannot achieve the function of repeated locking on orbit. The huge impact generated by the separation has a serious impact on the attitude and precision control of the space manipulation platform. [0003] In recent years, with the development of space station construction and space detection technology, the space-to-earth shuttle system needs to lock-release-relock the transported large-scale and heavy-duty materials. There are no space control platforms in orbit. Mission requirements for shock release of delicate payload...
