The invention relates to the technical field of unmanned aerial vehicle take-off and landing support systems, in particular to an unmanned aerial vehicle pneumatic ejection recovery device which comprises a frame body, sliding frames are slidably connected to the two ends of the frame body and slide in the length direction of the frame body, and at least one amplification pulley block is arranged at each of the two ends of the frame body. Each amplification pulley block comprises a fixed pulley rotationally connected to the frame body and a moving pulley rotationally connected to the sliding frames, the frame body is connected with a power assembly for driving the two sliding frames to move synchronously, and reversing pulley blocks are arranged at the two ends of the frame body; the two sliding frames are jointly and fixedly connected with a traction cable, the traction cable is wound on the moving pulleys, the fixed pulleys and the guide pulleys, the number of turns of the traction cable wound on the moving pulleys and the fixed pulleys at the two ends of the frame body is the same, and the traction cable is connected with a traction assembly. The device can meet the take-off condition of the unmanned aerial vehicle on the premise of low cost and low space occupation by amplifying the moving distance of the traction cable driven by the power assembly.

    本发明涉及无人机起降保障系统技术领域,具体涉及一种无人机气动弹射回收装置,包括架体,架体两端均滑动连接有滑动架,滑动架沿架体长度方向滑移,架体两端均设置有至少一组放大滑轮组,每组放大滑轮组均包括转动连接于架体上的定滑轮和转动连接于滑动架上的动滑轮,架体连接有带动两个滑动架同步移动的动力组件,架体两端均设置有换向滑轮组;两个滑动架共同固定连接有牵引缆,牵引缆缠绕于每个动滑轮、定滑轮和导向滑轮上,架体两端的动滑轮和定滑轮上牵引缆缠绕的圈数相同,牵引缆上连接有牵引组件,本申请具有能够通过放大动力组件带动的牵引缆移动距离的方式来让弹射装置能够以低成本、低空间占用的前提下满足无人机的起飞条件。
