Space rope catching and locking device

The invention discloses a space rope catching and locking device, which comprises a catching device body, a locking mechanism, a rope cable and mechanical paws, wherein the mechanical paws are fixedly arranged on an installation support frame arranged at the upper part of the catching device body, three sets of mechanical paws are controlled to synchronously rotate through a driving motor, the opposite surrounding is realized, a three-finger structure is formed, the locking mechanism is positioned at two sides of the upper part of the catching device body and is in mutually vertical and symmetrical installation with the mechanical paws. The rope cable is fixedly connected with the center position of the bottom end of the catching device body, and the other end of the rope cable is connected with a space mobile platform. During the target catching, cameras approach to and guide the catching device to go close to the garget when the cameras enter the measurement blind region, the target is implemented and is tightly locked and limited in a certain range for realizing the reliable catching capable of preventing the target escaping. The catching and locking device is applied to a system in the structure including the space mobile platform, the space rope and the space rope catching and locking device, and the space rope catching and locking device has the advantages that the structure is simple, the reliability is high, and the space rope catching and locking device is suitable for catching and locking single-rod type targets.
