The invention relates to the technical field of spacecraft general assembly, in particular to an airship cabin section butt joint lifting appliance under the condition of high center of mass and a using method thereof, and the airship cabin section butt joint lifting appliance comprises an upper hanging assembly, a lower hanging assembly, a plurality of vertical slings and a levelness fine adjustment assembly; the top ends of the vertical slings are connected with the upper hanging assembly, and the bottom ends of the vertical slings are connected with the lower hanging assembly. The levelness fine adjustment assembly is installed at the bottom end of the upper hanging assembly. Before hoisting, the axial length of each vertical sling is adjusted so as to roughly adjust the levelness of the bottom surface of the to-be-hoisted cabin section when the to-be-hoisted cabin section is hoisted. The levelness fine adjustment assembly can effectively prevent the cabin section to be hoisted from toppling over in the hoisting process. By means of the levelness fine adjustment assembly, the levelness of the bottom face of the to-be-hoisted cabin section can be finely adjusted when the to-be-hoisted cabin section is hoisted, the to-be-hoisted cabin section does not need to be repeatedly hoisted, the length of each turnbuckle does not need to be adjusted, and the turnbuckles do not need to be disassembled and assembled many times, so that the height difference between the bottom face of the hoisted cabin section and the top face of the lower fixed cabin section is rapidly adjusted to be smaller than 5 mm; and the hoisting period is shortened.
本发明涉及航天器总装技术领域,尤其涉及一种高质心条件下飞船舱段对接吊具及其使用方法,包括上吊挂组件、下吊挂组件、多个竖吊索和水平度精调组件;多个竖吊索的顶端分别与上吊挂组件连接,底端分别与下吊挂组件连接;水平度精调组件安装于上吊挂组件的底端。在吊装之前,调节每个竖吊索的轴向长度,以粗调待吊装舱段被起吊时底面的水平度。水平度精调组件能够有效地防止待吊装舱段在吊装过程中发生倾倒。借助水平度精调组件,能够精调待吊装舱段被起吊时底面的水平度,无需再反复起吊待吊装舱段和调整每个花篮螺丝的长度,也无需再多次拆装花篮螺丝,使得被吊装舱段的底面与下方固定舱段的顶面之间的高度差很快地调整至5mm以下,缩短了吊装周期。
