Rope collecting and releasing device for multiple sheaves

Abstract

The invention provides a rope collecting and releasing device for multiple sheaves. The rope collecting and releasing device comprises a rope collecting part and a rope releasing part, wherein the rope collecting part comprises a sheave driving shaft, a plurality of sheaves which are arranged on the sheave driving shaft in a sleeving manner, ejection mechanisms which correspond to the sheaves, a rope collecting driving gear, a rope collecting motor combination and other connecting components; the rope releasing part comprises a rope releasing screw rod, a screw rod driving gear, a rope releasing motor combination and other connecting components. The rope collecting and releasing device disclosed by the invention is a general device which can perform rope collecting and rope straining on space nets or space flying claws and can perform subsequently rope releasing on the space nets or the space flying claws, after the multiple space nets or the multiple space flying claws are sequentially transmitted and released, in particular to a device suitable for cleaning space fragments which can operate rope collecting and releasing on the subsequent space flying claws after the multiple space nets or the multiple space flying claws are transmitted and released. According to the rope collecting and releasing device disclosed by the invention, rope collecting and releasing of the multiple space flying claws can be realized only by utilizing two driving sources, and the various aspects of the requirements for resource allocation when multiple space flying claw systems are used can be greatly reduced, and the rope collecting and releasing device disclosed by the invention has the beneficial effects of being simple in principle, reliable in service and the like.

Description

technical field [0001] The invention relates to the technical field of space debris removal equipment, and in particular to a multi-cable pulley reeling and releasing device capable of reeling and subsequent release of flying nets or flying claws after multiple sets of flying nets or flying claws are launched and released sequentially. Background technique [0002] With the utilization of space orbit resources by human beings, more and more abandoned satellites are left on them, and the natural retention time of abandoned satellites in orbit ranges from decades to hundreds of years; Abandoned satellites not only seriously threaten the safe operation of normal spacecraft, but also occupy valuable orbital resources, so it is necessary to remove abandoned satellites in orbit. [0003] At present, there is a design scheme of using flying nets or flying claws to capture space discarded satellites for on-orbit clearance, but there is no way to arrange multiple sets of flying nets ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-cable pulley cable collection and release device to solve the problem in the prior art that a set of flying net cable collection and release devices cannot be used to complete the control of multiple sets of flying nets and flying claw devices
