Abstract

The invention relates to a lever counter weight type gravity compensation device used for one-dimension deployed antenna ground deployment tests of spacecrafts such as satellites. The lever counter weight type gravity compensation device comprises a supporting assembly, a rotating plate assembly and a bottom plate assembly; the supporting assembly is composed of an adaptor, a rotating shaft, a plastic roller, a roller support, a pressure sensor and the like; the rotating plate assembly is composed of a rotating plate, a counter weight, rotating supports, a damper gear, an intermittent gear, bearings, a key and the like; the bottom plate assembly is composed of a bottom plate, bottom plate locking levers, sucked type electromagnets, a limiting pin, bottom plate guide rods and the like. When an antenna is deployed, the compensation device is in a sucked and combined state, and the sucked type electromagnets are powered on and sucked and combined with the rotating plate; after the antenna is deployed, the sucked type electromagnets are powered off, the rotating plate can rotate stably under the functions of the counter weight, the intermittent gear, the damper gear and the like, and finally the rotating plate supports the antenna to compensate the gravity. By means of the lever counter weight type gravity compensation device, the problem of gravity compensation of space antenna ground deployment tests is solved, the structure of the device is simple, the operation is convenient, the compensation force is adjustable, and no impact exists.

Description

technical field [0001] The invention relates to a lever counterweight type gravity compensation device, in particular to a set of devices capable of performing gravity compensation on a large one-dimensional extending antenna with variable diameter or fixed diameter, and displaying the compensation force in real time. Background technique [0002] Since the beginning of the 21st century, the aerospace industry of various countries has achieved rapid development, and the technology of space vehicles such as satellites has continued to improve. Large-scale one-dimensional extension antennas are an important component of various spacecraft. During the development process, the zero-gravity one-dimensional deployment test of the antenna is a An essential test content, so a set of gravity compensation device is needed to compensate the force to simulate the zero gravity environment. [0003] By reviewing the existing literature, it is found that the gravity compensation of the lar...
