Satellite universal type force balancing lifting system

Abstract

The invention provides a satellite universal type force balancing lifting system, which comprises a fixed main beam assembly (1), an extensible main beam assembly (2), a auxiliary beam assembly (3), acaster assembly (4), and a lifter assembly (5); the lifter assembly (5) is mounted on the fixed main beam assembly (1) and drives the extensible main beam assembly (2) to move between an extended position and an retracted position. According to the satellite universal type force balancing lifting system, it is ensured that a satellite is lifted multiple times, manual adjustment is not required, all lifting points can maintain uniform stress, and compared with a cross load lifting device, the application range of the satellite universal type force balancing lifting system is wider; and the satellite universal type force balancing lifting system adopts the lever principle to distribute lifting point force of a satellite load lifting device, and is suitable for lifting the satellites with mass centroid and centroid not coinciding obviously.

Description

technical field [0001] The invention relates to a satellite hoisting system, in particular to a general-purpose force balance hoisting system for satellites. Especially the satellite hoisting uniform force device. Background technique [0002] Satellite hoisting generally adopts a cross spreader. During the satellite hoisting process, affected by the status of the spreader and the slight difference in the connection mode between the suspenders and shackles, it cannot guarantee that each lifting point is evenly stressed, so that the satellite structure, the entire satellite, etc. The spreaders are all in a relatively bad stress state. [0003] Usually, before the satellite is hoisted, the sling is found to be slack, and it is considered that the lifting point is not stressed. Generally, the slack of the sling is adjusted by the ring screw of the sling connector until all the slings are in a tensioned state. This method has the following problems: [0004] 1) Repeated adjus...

AI Technical Summary

Problems solved by technology

[0004] 1) Repeated adjustment of the lifting ring screw, the adjustment efficiency is low, the risk of satellite operation is increased, and the uniform force cannot be guaranteed quantitatively;

[0005] 2) The cross spreader cannot be used for hoisting satellites whose centroid and centroid obviously do not coincide;

[0006] 3) Cable-stayed slings are required above the cross spreader, which puts forward higher requirements for the hanging height of the factory building;

[0007] 4) The current cross spreader cannot meet the requirements of model versatility

Adding a uniform force device at the lower end of the ordinary satellite spreader can effectively solve the problem of uneven force on the satellite spreader, but this device cannot be used alone as a spreader and must be installed under the existing satellite spreader
