High-precision vertical docking system of large spacecraft

Abstract

The invention discloses a high-precision vertical docking system of a large spacecraft. An upper capsule is hung, stopped and fixed through an upper capsule hanging and stopping supporting and adjusting system when being adjacent to the docking position, a docking precision measuring and monitoring system is adopted for performing non-contact precision measurement and precision adjusting guidance on the docking face of two capsules, the position precision of the lower capsule is adjusted through a lower capsule reverse docking posture adjusting and transferring system so that the precision requirement of the docking face can be met, micro-impact reverse docking is performed so that precise docking between the lower capsule and the upper capsule can be achieved, a visual docking guaranteeing system and an operation accessibility guaranteeing system are adopted so that operation accessibility in the docking process can be achieved, the docking risk is reduced to be minimum, and efficient, precise and stable docking of the large complicated spacecraft is achieved. The system is easy to operate and simple in achievement procedure, the docking risk of the large spacecraft is effectively controlled, assembly efficiency is improved, adaptability is high, the system is applicable to docking of various capsule segment type spacecraft structures, and the system has an important effect on improving the assembly precision and the assembly quality of the spacecraft.

Description

technical field [0001] The invention relates to the field of vertical docking of large spacecraft, in particular to a high-precision vertical docking system of large spacecraft. Background technique [0002] Based on the complex functional requirements of the spacecraft, the docking between the cabins is usually accompanied by difficulties such as high docking accuracy requirements, complex distribution of load units near the docking surface, and poor visualization and operability of the docking surface. Compared with horizontal docking, the vertical docking process is simple, the implementation cost is lower, the versatility is stronger, and it is more in line with the working state of the vertical launch of the spacecraft. Therefore, the vertical docking technology between large cabins has an irreplaceable role. [0003] At present, the vertical docking assembly of large spacecraft cabins still mostly uses hoisting or moving ground tooling to move the two sides of the dock...
