Abstract

The invention discloses an on-track plugging device which is convenient to perform on-track operation by an astronaut, easy to apply force, uniform in plugging stress, and high in visibility. The on-track plugging device mainly comprises a mobile phone rack component, a gear component, a ball screw component, and a bolt gear rack component. Through above components, the linear movement in a plugging work is transformed to be a rotating movement; the plugging work of a spaceflight module is realized by means of the principle of acting force and counter-acting force. The on-track plugging device provided by the invention meets the design of ergonomics, and is easy to plug when astronaut replaces the device on track; moreover, the linear movement for the plugging action is transformed to be rotating movement, thus the astronaut operation is benefited, and force increasing effect is obvious; four force applying points are symmetrically arranged by taking the connector as a center approximately; the force applying acting points for plugging are dispersed, the connector stress is uniform and free from lateral moment, and the connector is not easy to damage; the shortcomings of difficulty of secondary plugging in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of aerospace on-orbit maintenance, in particular to an on-orbit plugging and unplugging device. Background technique [0002] The on-orbit maintenance of spacecraft can prolong the service life of the spacecraft and enhance its system capabilities, etc., which is of great significance in the development of spaceflight. On-orbit maintenance of spacecraft can be divided into manned on-orbit maintenance and autonomous on-orbit maintenance according to whether astronauts participate. Autonomous on-orbit maintenance relies on mechanical devices such as robotic arms and dexterous hands to quickly and conveniently complete some simple maintenance tasks; on-orbit maintenance with astronauts participating in maintenance tasks can complete more complex actions, with higher maintenance reliability and maintenance content. More broadly, in more complex space activities, the role of manned on-orbit maintenance is becomi...
