Abstract
This invention discloses a propellant venting connector docking and locking device for venting propellant from a rocket being recovered and suspended from a robotic arm on a launch tower. The docking and locking device includes an installation platform; an installation plate driven by a first drive mechanism to rotate vertically on the installation platform; multiple rocket-holding mechanisms evenly distributed circumferentially on the installation plate, driven by a second drive mechanism to synchronously move radially toward each other towards the center and synchronously move radially away from each other towards the center; multiple rocket-bearing mechanisms evenly distributed circumferentially on the installation plate to support the rocket; an industrial robot is installed on the installation plate, and a connector is provided at the end effector of the industrial robot. The connector is driven by the industrial robot to dock with the rocket's venting port and is used to vent the propellant. This invention can effectively reduce the safety risks to personnel involved in the handling of rocket propellant after recovery and improve the efficiency of propellant venting and handling.
