The invention provides a rope-driven double-platform repeatable space locking and releasing mechanism, and belongs to the technical field of locking and releasing of space gravitational wave detection devices. The problems that in the prior art, after separation, gaps are not controlled, the collision risk is high, and the structure is complex are solved. The device comprises two groups of locking mechanisms, a base plate, a floating lower platform, a floating upper platform and a rope-driven U-shaped rod, the two groups of locking mechanisms are symmetrically arranged, the lower parts of the two groups of locking mechanisms are fixedly connected with the base plate, the floating upper platform is erected in a locking working space at the upper ends of the two groups of locking mechanisms, and the floating lower platform is positioned below the base plate. After separation is achieved, triggering and actuating elements such as a mooring rope and a disc spring which have completed functions are all reserved at the platform end and can be repeatedly used, waste is not generated, and follow-up work of a spacecraft is not affected. The locking and releasing process can be repeatedly operated, and after releasing is achieved, triggering and actuating elements such as the U-shaped rod and the compression spring which have completed functions are all reserved on the platform end and can be repeatedly used.

    本发明提出了一种绳驱动的双平台可重复空间锁紧释放机构,属于空间引力波探测装置的锁紧释放技术领域。解决解决现有技术中的分离后间隙不受控、碰撞风险高、结构复杂等问题。它包括两组锁紧机构、基板、浮动下平台、浮动上平台和绳驱U型杆,两组锁紧机构对称设置,且下方连接与基板固连,浮动上平台架于两组锁紧机构上端的锁紧工作空间内,浮动下平台位于基板下方。本发明实现分离后,已完成功能的缆绳、碟簧等触发和作动元件均保留在平台端上,且可重复使用,不会产生废弃物,也不会影响航天器后续的工作。本发明的锁紧释放过程可重复操作,实现释放后,已完成功能的U型杆、压簧这种触发和作动元件均保留在平台端上,且可重复使用。
