[0021] The present invention is further described below with reference to the accompanying drawings:

[0022] The utility model mainly consists of a launching frame and a pulley. The launching frame is fixed to the ground through anchor bolts, the pulley is placed on the launching frame through a slider, and the UAV is placed on the groove of the pulley through a pin shaft.

[0023] Specifically, such as Figure 1 As shown, a ground rapid multi-machine launch platform includes a launch frame 1 and a pulley 2. The pulley 2 includes a booster 3, a pulley limit plug 4, a shear pin 5, a slider 6, a groove 7, and a pulley body 8. Figure 2 As shown. The launcher 1 includes a profile welding structure 9 and a guide rail 10. Figure 3 shown.

[0024] The launcher 1 has a profile welded structure 9 at the bottom and a guide rail 10 at the top. The guide rail 10 and the profile welded structure 9 are connected by bolts. The bottom of the profile welded structure 9 is fixed to the ground by anchor bolts. The guide rail 10 has a certain pitch angle to facilitate providing the pitch speed and pitch angle when the UAV is launched.

[0025] A booster 3 is provided at the tail end of the pulley body 8 of the pulley 2, and a pulley limit plug 4, a shear pin 5, and a slider 6 are provided at the bottom of the pulley body 8. The shear pin 5 fixes the pulley limit plug 4 to the bottom of the pulley body 8. The pulley limit plug 4 and the shear pin 5 are used to limit the sliding of the pulley 2 on the guide rail 10. The bottom surface of the pulley body 8 slides on the guide rail 10 through the slider 6. The top of the pulley body 8 has multiple grooves 7, which are connected to the drone through the multiple grooves 7.

[0026] Working Principle: The trolley is secured to the launch platform via shear pins and rail plugs, and the drone is placed on the trolley. During launch, thrust shears the shear pin bolts, pushing the launch platform and trolley onto the rails. After leaving the rails, the trolley separates from the launch platform. After launch, the rail plugs are removed, and the next batch of trolleys and drones are replaced using the same process as above.

[0027] This launch method has been verified through multiple ground launch tests and multiple launch tests have been completed, and its beneficial effects have been verified.
