The invention discloses a double-insurance rapid separation device, and belongs to the technical field of spaceflight rapid separation. The butt joint device comprises a butt joint and a butt joint body. The butt joint comprises a joint mounting seat and a spherical structure, the spherical structure is connected with the joint mounting seat through a ball head rod, and a rod groove is formed in the ball head rod; the butt joint body comprises a butt joint body mounting seat and a plurality of butt joint units, and the plurality of butt joint units are matched to form a ball socket structure; the butt joint unit comprises a shape-following clamping jaw and a force control assembly, a groove structure is arranged on the inner side of the shape-following clamping jaw, a pressing ball or a pressing roller is arranged at the upper end of the shape-following clamping jaw, the lower end of the shape-following clamping jaw is hinged to the connecting body installation base, and the outer side of the shape-following clamping jaw is connected with the connecting body installation base through the force control assembly. The butt joint body and the spherical structure are matched to be in a closed state, and axial movement of the rocket is prevented; when the rocket is launched, thrust can be generated, axial constraint on the rocket is relieved, and the rocket can be quickly responded and separated under the action of the thrust, so that the rocket can smoothly fly out of the launch canister.

    本发明公开了一种双保险快速分离装置,属于航天快速分离技术领域。其包括对接头及对接体;所述对接头包括接头安装座及球型结构,所述球型结构通过球头杆与接头安装座连接,球头杆上有杆凹槽;所述对接体包括接体安装座及多个对接单元,多个对接单元配合形成球窝结构;所述对接单元包括随型卡爪及控力组件,所述随型卡爪内侧有凹槽结构,所述随型卡爪上端有压紧球或压紧辊,所述随型卡爪的下端与接体安装座铰接,所述随型卡爪的外侧通过控力组件与接体安装座连接。本发明对接体与球型结构配合呈闭合状态,防止火箭发生轴向运动;火箭发射时会产生推力,解除对火箭的轴向约束,在推力作用下能够快速响应分离,确保火箭能够顺利从发射筒内飞出。
