On-orbit maintenance quick-connection system based on double-conjugate cam assist principle

Abstract

An on-orbit maintenance quick connection system based on a bi-conjugate cam assistance principle relates to the field of on-orbit maintenance in aviation and spaceflight. The problem on how to complete an on-orbit maintenance process of an on-orbit replaceable unit with large plugging and unplugging force quickly and assist astronauts is solved. The on-orbit maintenance quick connection system includes a quick jack mounting plate on which a quick jack and positioning guide pins are fixed, an on-orbit replaceable unit, a quick socket mounting plate which is fixed to the lower end of the on-orbit replaceable unit, two assistance support lugs which are respectively fixed to the left and right sides of the lower end of the on-orbit replaceable unit and are symmetric about the center of mass of the on-orbit replaceable unit, and two assistance mechanisms which are respectively fixed to the two sides of the quick jack mounting plate. The two assistance mechanisms have a one-to-one correspondence relationship with the two assistance support lugs. When the two assistance mechanisms are shifted, the two assistance support lugs are driven to make the quick jack plugged into a quick socket. The two assistance mechanisms rotate 90 degrees simultaneously to complete plugging and unplugging of the on-orbit replaceable unit. The on-orbit maintenance quick connection system has the advantages of simple structure, low weight, small size and easy installation.

Description

technical field [0001] The invention relates to the technical field of on-orbit maintenance in aerospace, in particular to an on-orbit maintenance quick-connect system based on the principle of double-conjugate cam power assistance. Background technique [0002] With the rapid development of aerospace technology, space activities are more frequent, the number of spacecraft operating in orbit is increasing, the structure and composition of spacecraft are becoming more and more complex, and the performance and technical level are also constantly improving. However, due to the impact of launch costs and the objective environment, spacecraft are rarely maintained, maintained, and upgraded as ground equipment is. Moreover, the space environment in which spacecraft are located is complex and harsh, and spacecraft often fail to function during their missions. In case of failure, the loss is huge. Therefore, how to ensure the durable and stable operation of the spacecraft in the sp...
