A space load docking locking interface device for realizing emergency unlocking and locking indication

Abstract

The invention discloses a space load butt locking interface device capable of realizing emergency unlocking and locking instruction and belongs to the technical field of a space application device. The space load butt locking interface device comprises an active end and a passive end, which are fixedly connected with an exposure load and a spacecraft cabin exposure platform respectively. Through cooperation of a main locating pin of the active end and a main positioning hole in the passive end, a mechanical arm is guided to enable the exposure load to be butted to a position to be installed; through a screw rod of the active end, a frame A main body, a frame A branch body, a frame B main body and a frame B branch body are driven to move along a guide shaft to realize rigid locking of the exposure load; when the device cannot realize unlock through an electric mode, mechanical unlocking of the active end and the passive end is finished manually by operating an emergency unlocking fixation assembly of the active end; and the state of a locking mechanism is indicated through a position state indicating mechanism of the active end. The device can assist the mechanical arm to realize guiding positioning and butting, rigid locking and manual unlocking of the exposure load and a spacecraft cabin.

Description

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