Portable universal transportation tool for aerospace extra-vehicular product

Abstract

The invention relates to a portable universal transportation tool for an aerospace extra-vehicular product, and belongs to the field of design of extra-vehicular maintenance equipment of a space station power subsystem cabin. The portable universal transportation tool comprises a handle, a handle grip, a guide base, a locking head, two locking hooks, a torsion spring and equipment to be transported; the equipment to be transported is horizontally placed, the guide base is installed in the middle of the top end of the equipment to be transported, and a grip of the handle is vertically placed upwards; the axial direction of the handle grip is vertically and fixedly installed at the bottom of the handle, the locking head is installed at the bottom end of the handle grip, the torsion spring isarranged inside the locking head, the two locking hooks are symmetrically arranged on the two sides of the locking head, the two locking hooks are matched with the two leading-out angles of the torsion spring, the two locking hooks extend into the guide base through the locking head and are fixedly connected, so that a lifting handle drives the the equipment to be transported to move, so that thetransportation is achieved. The portable universal transportation tool adapts to the operation work efficiency generated after an astronaut wears the extra-vehicular space suit, the working efficiency is improved, and the unnecessary accidents are avoided.

Description

technical field [0001] The invention belongs to the field of extravehicular maintenance equipment design of a power sub-system of a space station, and relates to a portable general transport tool for spaceflight extravehicular products. Background technique [0002] In order to ensure the stable on-orbit operation of the space station and meet the mission requirements of the space station, astronauts have to do a lot of work in the extravehicular space, involving many extravehicular products, especially the maintenance and replacement of the extravehicular equipment of the power subsystem. [0003] Considering the variety of extravehicular products, the mechanical interface design of extravehicular products should be able to adapt to the astronaut's field of view and operating ability after wearing the extravehicular spacesuit, and the mechanical interface design should support the astronaut to effectively judge the installation in place. and other problems, the current main...

Problems solved by technology

[0003] Considering the variety of extravehicular products, the mechanical interface design of extravehicular products should be able to adapt to the field of view and operation ability of astronauts wearing extravehicular spacesuits, and the design of mechanical interfaces should support astronauts to effectively judge whether the installation is in place. And other problems, the current maintenance of extravehicular products does not design a portable and universal means of transportation to assist astronauts to complete various maintenance operations outside the cabin, resulting in the unexpensive work of astronauts outside the cabin and affecting work efficiency , increasing the uncertainty of the extravehicular operations
