Connecting rod linkage type hatch cover turnover locking mechanism and turnover locking method thereof
The invention discloses a connecting rod linkage type hatch cover overturning locking mechanism and an overturning locking method thereof, and relates to the technical field of overturning and locking of spacecraft hatch covers. The hatch cover connecting mechanism solves the problems that an existing hatch cover connecting mechanism cannot meet rapid and stable unlocking opening, closing unlocking and closing locking, and a hatch cover cannot be opened possibly due to the fact that a locking mechanism and a turnover mechanism operate at the same time. The turnover mechanism, the locking mechanism and the crane are matched to complete the turnover and locking functions of the hatch cover, and a radial lock and an axial lock in the locking mechanism are designed to be crank connecting rod locking mechanisms. The hatch cover is firstly unlocked through the locking mechanism, and then the hatch cover is turned over through the cooperation of the crane and the turnover mechanism. A fixed hinge is designed at the rear end of the cabin, and the cabin cover turns backwards around the fixed hinge when being opened. According to the invention, reliable connection of cargoes, pallets and the hatch cover body in the ascending process is met, meanwhile, the functions of rapid and stable unlocking and opening, closing and unlocking and closing and locking are achieved, and linkage type unlocking and overturning can be achieved.
连杆联动式舱盖翻转锁止机构及其翻转锁止方法，它涉及一类航天器舱盖的翻转与锁紧技术领域。本发明解决了现有舱盖的连接机构存在无法满足快速、稳定的解锁开启和关闭解锁和关闭锁紧，以及可能出现锁紧机构与翻转机构同时运行导致舱盖无法开启的问题。本发明由翻转机构、锁止机构和吊车配合完成舱盖翻转与锁止功能，锁止机构中的径向锁与轴向锁设计为曲柄连杆锁止机构。首先通过锁止机构先完成舱盖的解锁，再配合吊车与翻转机构完成舱盖翻转。舱后端设计有固定铰链，舱盖开启时绕着固定铰链向后翻转。本发明用于满足上行过程中货物、货盘与舱盖本体可靠连接，同时具备快速、稳定的解锁开启和关闭解锁和关闭锁紧的功能，能够实现联动式解锁与翻转。
