On-orbit dragging-off tool for case in manned spaceflight cabin

Abstract

The invention discloses an on-orbit dragging-off tool for a case in a manned spaceflight cabin, and belongs to the field of manned spaceflight systems. According to the technical scheme, a spaceflight electronic case is installed on the lower portion of a step frame of the spaceflight cabinet and linearly moves through a guide rail; a crank connecting rod precession device is rotationally connected to the guide rail through a crank connecting rod hinge device hinged to a hinge base of a front panel of the case, the rotating motion of the crank connecting rod precession device is converted into linear motion of the spaceflight electronic case along the guide rail, and the crank connecting rod precession device rotates clockwise or anticlockwise. And the spaceflight electronic case is linked to linearly move forwards and backwards along the guide rail, so that on-orbit dragging of the spaceflight electronic case and a back plate is quickly realized. In-orbit dragging of the case and the back plate is achieved through a lever mechanism and a crank sliding block mechanism, operation is convenient, operation force and physical output of astronauts can be effectively reduced, the manned spaceflight operation condition can be adapted, and the in-orbit operation capacity of the astronauts and the pulling force needed for disassembling and assembling the case are met.

Description

technical field [0001] The invention belongs to the field of manned spaceflight systems, in particular to an on-orbit dragging tool for a chassis in a manned spaceflight capsule. Background technique [0002] As a scientific platform for humans to explore the mysteries of space, the biggest feature of the space station is that it can stay in space for a long time, providing a safe and reliable working environment for humans to directly participate in space scientific research. However, due to the long-term impact of the very harsh space environment such as high vacuum, low temperature, solar electromagnetic radiation, ionosphere, and earth radiation, the reliability of its airborne electronic equipment has been continuously reduced, and some functional modules cannot work normally. It directly affects the completion of the entire flight mission. Therefore, the problem of how to prolong the on-orbit operation period of spacecraft electronic equipment needs to be solved urgen...
