Abstract

The invention discloses an adjusting method for level hanging adjustment for a hanging tool based on hanging point adjustment. The adjusting method mainly comprises the following steps of hanging adjustment processes, such as level adjustment of the hanging tool per se, centering of a hanging hook (or a hanging ring of the hanging tool) with a crown block, levelness measurement and position adjustment, wherein a measurement value of an obliquity sensor on a hanging ring assembly is used as a reference for judging the centering of the crown block with the hanging hook; a measurement value of an obliquity sensor on a hanging beam is used as a criterion for judging the hanging levelness; position adjustment of the hanging points of the hanging tool is realized through the movement of a worktable XY in a plane; and on the premise of ensuring the centering between the crown block and the hanging hook, the hanging points of the hanging tool are adjusted to proper positions, so that two-dimensional levelness adjustment of the spacecraft in the hanging process is realized. According to the adjusting method for high-precision level hanging, disclosed by the invention, the levelness is less than 4.1 mm / m, and the level adjustment process can be completed within 180 s, so that digitalization and automation of measurement and adjustment processes are realized, the hanging precision and hanging efficiency are improved, the labor intensity of operating personnel is lowered, and the application value is remarkable.

Description

technical field

[0001] The invention belongs to the technical field of hoisting, and in particular relates to a method capable of realizing horizontal adjustment of a spacecraft. Background technique

[0002] During the final assembly process of the spacecraft, the precise docking and disassembly assembly of the spacecraft are completed by hoisting, and the docking surface needs to be kept level during the docking and disassembly process.

[0003] Because there is a certain difference between the actual center of mass position of the spacecraft and the theoretical center of mass position, the hoisting is tilted, causing point contact on the docking surface of the spacecraft, damaging the docking surface, and damaging the positioning pin (or guide pin); at the same time, due to the difference between the actual center of mass position and the theoretical The deviation of the center of mass position will cause rotation and swing during the hoisting process, which will easily c...
