The invention discloses a ground rocket recovery system based on a cable-driven parallel mechanism, and belongs to the technical field of carrier rocket recovery. The device comprises a fixed base, a cable-driven parallel mechanism and a rocket recovery cage. Position and attitude information between a target recovery rocket and a ground recovery platform is obtained and output in real time through the navigation communication module, and the following control module drives a winch motor to adjust the length of an outer rope of a parallel mechanism so as to adjust the attitude of a rocket recovery cage. And additional devices carried when the rocket is launched are reduced, so that the effective load of the target recovery rocket is improved. The target recovery rocket is gradually held and locked through the synergistic effect of the inner rope, the sliding block and the sliding groove arranged in the rocket recovery cage, and the performance and precision requirements for the attitude adjusting rocket engine can be lowered. Buffer devices are arranged at the ends of the parallel ropes, potential energy and kinetic energy of the recovery rocket are absorbed through the buffer devices, the speed of the target recovery rocket is gradually reduced to zero, and the safety and stability of the target recovery rocket are improved.

    本发明公开的一种基于索驱并联机构的地面火箭回收系统,属于运载火箭回收技术领域。本发明包括固定基座、索驱并联机构、火箭回收笼。本发明通过导航通讯模块实时获取并输出目标回收火箭和地面回收平台之间的位置和姿态信息,跟随控制模块驱动卷扬电机调节并联机构外绳索的长度实现调节火箭回收笼姿态,减少火箭发射时所携带附加装置从而提高对目标回收火箭的有效载荷。通过火箭回收笼内设有的内绳索、滑块和滑槽的协同作用逐渐抱紧锁定目标回收火箭,能够降低对调姿火箭发动机的性能和精度要求。在并联绳索端部布设缓冲装置,通过缓冲装置吸收回收火箭的势能和动能,使目标回收火箭的速度逐渐减小直至为零,提高对目标回收火箭的安全性和稳定性。
