Underwater simulation training frame vehicle for spacecraft cabin

Abstract

The invention discloses an underwater simulation training frame vehicle for a spacecraft cabin. The underwater simulation training frame vehicle comprises a frame mechanism, a driving wheel mechanism, a locking mechanism and a leveling mechanism. According to the unwheeling, the structural design of the frame mechanism is reasonable, the strength can meet the requirement for supporting a training cabin body, meanwhile, the requirement for light weight is met, and the service life of the unwheeling is effectively prolonged by spraying the anti-corrosion coating on the outer surface of the frame; the self-adaptive double-roller driving wheel mechanism is connected with the cabin body, so that the cabin body can rotate around the axis direction while the cabin body is horizontally and stably placed; the driving wheel mechanism can adapt to a certain amount of deformation of the cabin body, and the clamping stagnation phenomenon and the eccentric rotation phenomenon in the cabin body rotation process can be prevented; the locking mechanism can enable the training cabin to rotate in different quadrants and stay in any quadrant to work. The leveling mechanism can adapt to an uneven placement base plane, the height positions of the rack car and the cabin body are adjusted, meanwhile, the self-locking function is achieved, and the using safety of the rack car is guaranteed.

Description

technical field [0001] The invention relates to the technical field of manned spaceflight, in particular to an underwater simulation training frame vehicle used for a spacecraft cabin. Background technique [0002] The manned spacecraft has a cabin structure and needs to operate in a low-earth orbit in a microgravity environment for a long time. Therefore, before the completion of the space station, the cabin needs to conduct long-term underwater simulation training tests on the surface. The training frame vehicle is an important auxiliary equipment for the underwater low-gravity underwater simulation training test and assembly of the spacecraft cabin. The existing underwater simulation training vehicle can only realize the circumferential rotation of the spacecraft cabin. During the rotation process, if the spacecraft cabin itself has shape deformation, it will cause stagnation and eccentric rotation during the rotation process. The test The process is easy to damage the c...

The existing underwater simulation training vehicle can only realize the circumferential rotation of the spacecraft cabin. During the rotation process, if the spacecraft cabin itself has shape deformation, it will cause stagnation and eccentric rotation during the rotation process. The test Process vulnerable cabin

The locking device used to stop the cabin in different quadrant positions in the circumferential direction is complicated and inconvenient to stop and use
