A space load docking locking and emergency unlocking interface device

Abstract

The invention discloses a space load butting joint locking and emergency unlocking connector device and belongs to the technical field of space application equipment. The space load butting joint locking and emergency unlocking connector device comprises an active end and a passive end which are fixedly connected with an exposed load and a spacecraft cabin body exposure platform correspondingly; through matching of main locating pins on the active end and main locating holes in the passive end, a manipulator is guided to operate the exposed load to be butted to the position to be mounted; a motor reducer on the active end drives a lead screw to drive a main body of a rack A, split bodies of the rack A, a main body of a rack B and split bodies of the rack B to achieve rigid locking of the exposed load in the mode of moving along guide shafts; and when the butting joint locking device cannot be unlocked in an electric mode, mechanical unlocking of the active end and the passive end is manually accomplished by operating an emergency unlocking and fixing assembly at the active end. The space load butting joint locking and emergency unlocking connector device can assist the manipulator to realize guiding positioning butting joint, passive capture, active tightening, rigid locking and manual unlocking of the exposed load and the spacecraft cabin body.

Description

technical field [0001] The invention belongs to the technical field of space application equipment, and in particular relates to a space load docking locking and emergency unlocking interface device. Background technique [0002] Space vehicles such as space stations and manned spacecraft have arranged a large number of exposure load test platforms on the outer wall of the cabin to expand the exposure test capabilities of space vehicles. At present, the International Space Station has used various forms of payload docking and locking interface devices to support exposure experiment tasks. [0003] However, for the exposed load outside the cabin and the exposed platform outside the cabin, the docking and locking interface device in the prior art cannot automatically capture the exposed load outside the cabin, the degree of automation is not high, the operation ability of the astronaut or the mechanical arm is high, and the mechanism is complicated. Poor maintainability and l...
