Space on-orbit capture device

Abstract

The embodiment of the invention provides a space on-orbit capture device. The space on-orbit capture device comprises multiple internode connecting mechanisms, driving mechanisms and scissor mechanism arrays. Each internode connecting mechanism is provided with multiple installing positions. Two driving mechanisms are arranged between every two adjacent internode connecting mechanisms. Each driving mechanism comprises a driving device, a first swing arm assembly and a second swing arm assembly, the two ends of the first swing arm assemblies are connected with one ends of the driving devices and the installing positions of the internode connecting mechanisms respectively in a pivoting mode, the two ends of the second swing arm assemblies are connected with the other ends of the driving devices and the installing positions of the internode connecting mechanisms respectively in a pivoting mode, the driving devices drive the first swing arm assemblies and the second swing arm assemblies to swing, and the swing directions of the first swing arm assemblies and the second swing arm assemblies are opposite. The space on-orbit capture device has stretching, retracting and bending functions and is high in capture capacity.

Description

technical field [0001] The invention belongs to the field of aerospace technology, in particular to a space on-orbit capture device. Background technique [0002] With the emergence of new space mission requirements such as the assembly of the International Space Station on orbit, space debris removal, spacecraft fueling on-orbit, and capture of enemy satellites, space agencies of various countries have gradually realized that space on-orbit capture devices are the key to future space debris removal and maintenance. An important technology in space strategic offensive and defensive missions. [0003] However, the space on-orbit capture device of traditional spacecraft uses rigid telescopic rods or mechanical arms to capture on-orbit targets, which cannot achieve large fault-tolerant capture of space target objects, and the device itself has flexible movement, deformation Ability, unable to implement active mobile capture of escaping targets.
