High-redundancy insertion-pin-type connecting mechanism used for space truss connection

Abstract

The invention discloses a high-redundancy insertion-pin-type connecting mechanism used for space truss connection. The high-redundancy insertion-pin-type connecting mechanism comprises a connector anda connecting groove, wherein the connecting groove is provided with a groove part; the connector is provided with a protruding part; the protruding part of the connector is in cooperative connectionwith the groove part of the connecting groove; a first magnet is arranged at the bottom of the groove part; a second magnet generating the attractive force with the first magnet is arranged at the topof the protruding part; a plurality of insertion pins are arranged around the connecting groove; first magnetic poles are arranged at the top ends of the insertion pins; insertion holes correspondingto the insertion pins are arranged around the protruding part; the insertion holes are provided with second magnetic poles generating the attractive force with the first magnetic poles; and the second magnetic poles attract the first magnetic poles so that the insertion pins can be inserted into the insertion holes.

Description

technical field [0001] The invention relates to the technical field of space operation and space truss construction, in particular to a multi-redundant plug-type connection mechanism for space truss connection. Background technique [0002] With the rapid development of space technology, the role of space systems in human daily life has become more and more prominent. The current research situation of space technology has gradually expanded from exploring and utilizing space to exploring, utilizing and controlling space. With the continuous improvement of human beings' capabilities in space research, development and application, space experiments have also put forward higher and higher requirements for test conditions, and many tasks require astronauts to operate out of the warehouse. However, the space environment of the universe is complex, whether it is a vacuum environment, cosmic radiation, or fast-moving space debris, they are all very dangerous. The present invention...

AI Technical Summary

Problems solved by technology

[0009] Screw fixing is a traditional fixed connection method, but it needs to cooperate with screws and nuts, and install and fix by rotating. The problem in operation is that in addition to the connected parts, there are additional accessories screws and nuts. Even if the nuts are fastened on the connectors in advance, screws are required to complete the fixation

And even if it is manual operation, there is still the problem that the screw holes are difficult to align, not to mention the operation by the mechanical arm. Not only that, but the tightening degree of the screws is also difficult to evaluate

[0010] Compared with the screw connection method, the welding connection method has higher connection strength, but the process is very complicated

In the harsh space environment, the welding process is difficult to carry out, and the welding process will generate high temperature, which will have a serious impact on the working parts, and the heating of the structural components will also change their strength

[0011] Riveting is similar to screwing, and additional parts need to be added, but it is a one-time connection. If the rivet is removed after being equipped, it will be invalid and cannot be reused
