The invention provides an impact-reducing rope slow-release device suitable for a large parabolic antenna. The impact-reducing rope slow-release device comprises a damping support, a damper, a rope storage wheel, a rope guide mechanism, a truss connecting mechanism and a rope. Theoretical mechanical analysis shows that for the unfolding process of the large parabolic antenna truss, the impact force generated when the large parabolic antenna truss is unfolded in place can be reduced in a mode of reducing the unfolding speed. According to the invention, through slow release of the three ropes wound on the damper, the unfolding speed of the truss rod is reduced, and the unfolding impact of the large parabolic antenna is reduced. Compared with a truss unfolding antenna without the device, the large parabolic antenna can be slowly unfolded, and the structural safety and unfolding precision of the antenna are effectively guaranteed.

    本发明提供了一种适用于大型抛物面天线的减冲击绳索缓释装置,包括阻尼支架、阻尼器、绳索收纳轮、绳索导向机构、桁架连接机构、绳索组成。通过理论力学分析可知,针对大型抛物面天线桁架展开过程,可以通过减缓展开速度的方式,减小展开到位瞬时的冲击力。本发明通过缠绕在阻尼器之上的三处绳索的缓慢释放,从而减缓了桁架杆的展开速度,减小了大型抛物面天线的展开冲击。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抛物面天线的缓慢展开,有效保证了天线的结构安全和展开精度。
