Abstract

An inflation / deflation type air bag unfolding and coiling device relates to an unfolding and coiling device, and aims to solve the problem that in a conventional aviation spacecraft, the inflation structure is highly flexible, the folding and coiling are controlled difficultly, and the folding and unfolding process in the working state needs to be simulated and experimented on the ground, but no unfolding and coiling device capable of achieving the function of assisting the folding and the unfolding and unfolding controllability is available. The inflation / deflation type air bag unfolding and coiling device comprises a middle shaft, a driving and locking mechanism, a support saddle, an upper limiting stop lever, a lower limiting stop lever and a ventilation mechanism, wherein the ventilation mechanism comprises a ventilation connecting pipe, a rotary joint and an air valve; the support saddle comprises a base, two cross beams and two vertical beams; the middle shaft is arranged on the two vertical beams positioned between the two cross beams and can be rotated in the circumferential direction; the ventilation connecting pipe is connected to one vertical beam; the air valve is connected to the end part, opposite to the rotary joint, of the ventilation connecting pipe; and the other end of the middle shaft is connected with the driving and locking mechanism used for controlling the rotation and the stopping of the middle shaft. The device is used for inflatable structures of large-scale aviation spacecrafts.

Description

technical field [0001] The invention relates to an unwinding device, in particular to an inflatable and deflated airbag unwinding and rolling device. Background technique [0002] The large-scale aerospace inflatable structure needs to be folded and packaged on the ground for storage, and then inflated and unfolded after entering the work area to work normally. Due to the high flexibility of the inflatable structure and the difficulty in controlling the folding and unfolding, it is necessary to simulate the folding and unfolding process in the working state of the experiment on the ground. It is urgent to provide an unwinding device that can realize the auxiliary folding and unfolding function and controllable unfolding. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the inflatable structure of the existing aerospace vehicle is flexible and difficult to control the folding and unfolding. It is necessary to simulate the ...
