Horizontal adjusting sling for spacecraft

Abstract

The invention provides a horizontal adjusting sling for a spacecraft, which comprises a hoisting ring component, an XY workbench, a hoisting beam and straps, wherein the XY workbench is arranged on the hoisting beam; the top center of the XY workbench is hinged with the hoisting ring component through a universal joint; four straps are arranged below the hoisting beam; the XY workbench comprises an X workbench and a Y workbench; the X workbench slides on the Y workbench through a slide rail along the X direction; the Y workbench slides on the hoisting beam through a slide rail in the Y direction; and the hoisting ring component comprises a hoisting ring connected with a hook of a crane, a middle bearing structure and a two-dimensional inclination sensor b for measuring the angle of inclination of the hook relative to the crane. Compared with the prior art, the horizontal adjusting sling for hoisting the spacecraft solves the problem that automatic horizontal adjustment cannot be implemented in a two-dimensional plane, the digitization and automation in the measuring and adjusting process are achieved, the hoisting accuracy and hoisting efficiency are improved and the labor intensity of operators is reduced.

Description

technical field [0001] The invention belongs to the field of general assembly and hoisting of spacecraft, and in particular relates to an automatic horizontal adjustment hanger for spacecraft. Background technique [0002] In the process of spacecraft assembly, the precision docking and disassembly assembly of the docking of the load compartment and the platform, the docking of the satellite and the two-axis turntable, and the docking of the satellite and the whole satellite frame vehicle are important quality and product safety control points. [0003] At present, the precision docking and disassembly assembly of large-scale components and cabin sections are all completed by hoisting, and the docking surface needs to be kept level during the docking and disassembly process. [0004] Because there is a certain difference between the actual center of mass position of the spacecraft and the theoretical center of mass position, it is easy to cause the hoisting to tilt, causing ...
