Abstract

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.

Description

technical field [0001] The invention relates to the technical field of overturning and locking of a spacecraft hatch cover, in particular to a link linkage hatch cover overturning locking mechanism and an overturning locking method thereof. Background technique [0002] With the continuous development of manufacturing technology and space technology, cargo spacecraft and space-to-earth shuttle spacecraft will take on the heavy responsibility of the "space-to-earth transfer system". The cargo spacecraft has the function of an open cargo compartment, and its function is to meet the demand for two-way movement of non-pressurized cargo. Due to the harsh space environment, the longer the exposure to the space environment, the more difficult it is to provide safety protection for the astronauts. Therefore, the connection mechanism of the hatch cover not only needs to provide reliable connection between the cargo, the pallet and the spacecraft body during the upward process, but al...
