Abstract

The invention relates to a multifunctional active capturing device and a docking device. The multifunctional active capturing device comprises an active mechanism and a capturing assembly installed on the active mechanism, and the capturing assembly comprises a capturing driving part, a pair of guide wheels and a pair of capturing claws; the pair of capturing claws are correspondingly and rotationally assembled on the pair of guide wheels respectively, and the capturing driving part is in transmission connection with the pair of capturing claws through a steel wire rope and drives the pair of capturing claws to be folded or unfolded along the corresponding guide wheels. According to the multifunctional active capturing device, the capturing driving part drives the guide wheel to rotate so as to drive the steel wire rope on the guide wheel to move, the steel wire rope drives the capturing claw connected with the steel wire rope, folding or unfolding of the capturing claw is achieved, and the multifunctional active capturing device is simple in structure, flexible in configuration, wide in application and capable of being suitable for capturing and docking in a complex space environment.

Description

technical field [0001] The invention relates to the technical field related to space docking, in particular to a multifunctional active capture mechanism and a docking device. Background technique [0002] With the development of aerospace technologies such as space stations, manned moon landings, Mars exploration, deep space exploration, and on-orbit services, the docking technology is also constantly improving. The development of various aerospace technologies and the promotion of space missions also require docking technology Gradually increase. The active capture device in the existing active capture spacecraft docking system uses multiple joints, the system is complex, the development, production, and test costs are high, the reliability is low, and the size is large, and the layout is not flexible enough. Contents of the invention [0003] In order to solve one or several problems of the prior art, the present invention provides a multifunctional active capture devi...
