Load docking locking and locking indication interface device for space application

Abstract

The invention discloses a load docking locking and locking indication interface device for space application, and belongs to the technical field of space application equipment. The device comprises an active end and a passive end which are respectively and fixedly connected with an exposed load and an exposed platform of a spacecraft cabin; by matching main positioning pins, ball shearing pins and an auxiliary positioning pin at the active end with main positioning holes, a shearing hole, a kidney-shaped shearing hole and an auxiliary positioning hole in the passive end, a mechanical arm is guided to operate and dock the exposed load with the mounting position used for allowing the exposed load to be mounted; and by driving a lead screw through a motor reducer at the active end, a main body of a machine frame A, split bodies of the machine frame A, a main body of a machine frame B and split bodies of the machine frame B are driven to move along guide shafts to realize tightening of the exposed load, plugging and unplugging of electrical connectors of the exposed load, and rigid locking and reliable looseness prevention of the exposed load. Through the adoption of the device disclosed by the invention, the mechanical arm can be assisted to realize guide positioning and docking, passive capture, active tightening and rigid locking of the exposed load and the aircraft cabin.

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 locking indicating 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 lo...
