Circular ring lifting tool based on satellite bearing cylinder lifting

Abstract

The invention discloses a circular ring lifting tool based on satellite bearing cylinder lifting. Different from a general support rod type lifting tool, a circular ring lifting tool is used between a lifting beam and a satellite. Before the lifting tool is used, a lifting beam component is connected with a circular ring component by a quick-release stop pin, and then the circular ring component is connected with a frame at the upper end of a bearing cylinder through a plurality of fasteners, so that the lifting of the whole satellite or a single compartment is achieved. The quick-release stop pin can simplify the assembly of the lifting tool, and the fasteners can reinforce the frame at the upper end of the bearing cylinder in a lifting process of the whole satellite or the single compartment, so that stresses of connection points are relatively uniform, and the difficulty for designing a lifting point on the frame at the upper end of the bearing cylinder is reduced.

Description

technical field [0001] The invention relates to a lifting and transporting device for a satellite whole satellite or a single cabin, in particular to a ring hoisting device based on a satellite load-bearing tube with a load-bearing tube as the main load-bearing structure configuration. Background technique [0002] The satellite spreader is an important ground tool for the satellite's final assembly operation in the AIT stage. It is used to lift the satellite's entire satellite or a single cabin, so that the satellite's entire satellite or single cabin can move vertically and horizontally, and provide convenience for the subsequent AIT work of the satellite. It is a satellite Indispensable ground tooling during the development process. [0003] Usually, the satellite spreader adopts the beam spreader or the strut spreader according to the satellite configuration and the force-bearing conditions. The advantage of these two lifting methods is that the spreader has a better bea...

Problems solved by technology

However, the defects in the implementation process are as follows: 1) the structure is relatively complex, and the assembly requirements are high; 2) the use of a beam makes the satellite bear the torque caused by the uneven force of the lifting point during the lifting process, so that the satellite is in the lifting process. Slow rotation, there are potential safety hazards, and it is not conducive to the final assembly operation; 3) The use of a beam has high requirements on the local strength of the satellite lifting point, which may damage the satellite lifting point and affect the satellite lifting
