Spacing device for disassembling spatially large-bearing product

Abstract

The invention relates to a spacing device for disassembling a spatially large-bearing product, and belongs to the field of the in orbit disassembling design of the large-bearing product. The spacing device comprises a cabin flange plate, two positioning pins and two spacing blocks, wherein the cabin flange plate is of a disk-shaped structure; two positioning pins are symmetrically arranged on theinstallation surface of the cabin flange plate; the two spacing blocks are independently correspondingly cooperated with the two positioning pins; the spacing and the fixing of the cabin flange plateare realized; the two spacing blocks are in 180-degree distribution; when an outer cabin rises to an outer space, under a vacuum environment, screws between the cabin flange plate and the outer cabinare disassembled; under the spacing cooperation of the positioning pins and the spacing blocks, the circumferential spacing of the cabin flange plate is realized; and 12 screws are disassembled in sequence. According to the function requirements of an out-cabin product, the problem that the in-orbit disassembling and spacing design of the out-cabin product large-bearing product can be solved.

Description

technical field [0001] The invention belongs to the field of on-rail disassembly design for large load-bearing products, and relates to a limiting device for dismounting large-space load-bearing products. Background technique [0002] The construction of the space station, the third step of China's manned spaceflight project, will be built in 2020 and 2022. After the Chinese space station is put into normal operation, it will carry out scientific research and space experiments, and promote China's space science research and development into the world's advanced ranks. The construction of China's space station will aim at mastering the construction technology of the space station, using the technology synchronized with the times, and building a space station with the characteristics of the times. [0003] After the completion of the three-chamber combination of the Chinese space station, in order to meet the needs of long-life use and breakthroughs in space technology experi...
