The invention aims to provide an impact-reducing rope releasing device suitable for a truss antenna. The impact-reducing rope releasing device comprises the truss antenna, an extension arm, a rope, a guide wheel and a releasing device. The slow rotation of the rope wheel is realized through the motor and the speed reducer, so that the slow release of the rope and the slow increase of the length of the external rope are realized, the slow unfolding of the antenna is realized, and the impact of unfolding the antenna in place is reduced. Compared with a truss unfolding antenna without the device, the large truss antenna can be slowly unfolded, and negative effects of unfolding impact on antenna structure safety and unfolding precision are avoided.
本发明的目的在于提供一种适用于桁架天线的减冲击绳索释放装置,包括桁架天线、伸展臂、绳索、导向轮、释放装置组成。通过电机和减速器实现绳轮的缓慢转动,从而实现绳索的缓慢释放,外部绳索长度缓慢增加,从而实现天线的缓慢展开,从而减小了天线展开到位的冲击。相比于未使用该装置的桁架展开天线,本发明可以实现大型桁架天线的缓慢展开,避免展开冲击对天线结构安全和展开精度的负面影响。
