Applicable to the connecting device between the outer handle of the space vehicle and the exposed load

Abstract

The invention discloses a connecting device applied between an outboard handle of a spacecraft and an exposed load. The connecting device comprises an outboard-handle connecting device and an exposed-load connecting device; the outboard handle of the spacecraft and the exposed load are peripheral equipment; the outboard-handle connecting device and the exposed-load connecting device are connected; the exposed-load connecting device comprises a load mounting port and a load fastening and positioning assembly; the load mounting port consists of a spherical structure and a load mounting structure, and is in integral design; the load mounting structure is fixed with the exposed load; the load fastening and positioning assembly fixes the spherical structure by utilization of a fixing manner of pretightening force; and the outboard-handle connecting device fixes the handle by utilization of the fixing manner of pretightening force. Through the adoption of the connecting device disclosed by the invention, guiding mounting, reliable fixation, precise positioning and overload protection of the exposed load and the outboard handle are realized, so that the connecting device provides a technical support for rapidly mounting the exposed load and the outboard handle at set outboard positions.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a connecting device suitable for an outer handle of a spacecraft and an exposed load. Background technique [0002] Space vehicles such as space stations and manned spacecraft have arranged a large number of handles for astronauts on the outer wall of the cabin to facilitate the movement and fixation of astronauts when they leave the cabin. If some handles are used to fix small exposed loads outside the cabin, the space vehicle will be greatly expanded. exposure test capabilities. At present, the International Space Station has used the external handle to fix the material exposure experiment box to conduct long-term material exposure experiments. [0003] However, for the exposed load outside the cabin and the handle outside the cabin, the connecting device in the prior art cannot automatically capture the exposed load outside the cabin and the handle outside the cabin, and has...
