Abstract

The invention discloses an open type cargo hold and cam linkage type hatch cover turnover locking mechanism and a turnover locking method thereof, and relates to the technical field of hatch cover connecting mechanisms of freight airships, reusable carriers and the like. 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 power output end of the overturning transmission assembly is matched with the cam, and overturning of the hatch cover is achieved under driving of the overturning transmission assembly; the locking or unlocking of the cabin cover and the cabin seat is realized through the front end locking execution assembly under the driving of the front end locking transmission assembly; and under the driving of the rear end locking transmission assembly, the locking or unlocking of the cabin cover and the cabin rear end is realized through the rear end locking execution assembly. 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 hatch cover connection mechanisms for cargo spaceships and reusable carriers, in particular to an open cargo hold, cam-linked hatch cover flip locking mechanism and a flip 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 ...
