Description

Technical Field

[0001] This utility model relates to the technical field of loitering munition ejection devices, and in particular to a pneumatic ejection device for loitering munitions. Background Technology

[0002] In modern warfare, loitering munitions have become important combat equipment on the battlefield due to their integrated reconnaissance, surveillance and strike capabilities. As the key equipment for launching loitering munitions, the technical performance of the ejection device directly affects the combat effectiveness of loitering munitions. Traditional loitering munition ejection technology mainly relies on gunpowder ejection and rocket booster. Traditional gunpowder-launched munitions utilize the high-temperature, high-pressure gas generated by gunpowder combustion to propel loitering munitions. This method has many drawbacks. On the one hand, gunpowder is a flammable and explosive substance, posing significant safety hazards during production, storage, transportation, and use, and is prone to causing explosions that threaten the safety of operators and equipment. On the other hand, gunpowder combustion produces a large amount of smoke, flames, and noise, which not only easily exposes the launch site, exposing the launching device and operators to the risk of enemy attack, but also interferes with the operation of the loitering munition's own sensors, affecting its initial flight status and target identification capabilities. Therefore, these problems need to be addressed. Utility Model Content

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figure 1-4 The pneumatic ejection device for loitering munitions of this invention includes a frame 1. Four wheels 2 are rotatably mounted on the bottom of the frame 1, providing mobility and facilitating deployment in different locations. Two mounting slots are symmetrically formed on the frame 1, each containing a lifting component. A rotating shaft is rotatably mounted on one end of the top of the frame 1, with a guide cylinder 5 fixedly connected to it. The guide cylinder 5 ensures the smooth axial sliding of the support plate 7, providing a stable guiding path for the loitering munition's ejection. Mounting blocks are welded to both sides of the guide cylinder 5, with pneumatic components on the outer wall of each block. The support plate 7 slides within the guide cylinder 5 via these pneumatic components, allowing the loitering munition to be ejected at a specific speed and direction. Two guide posts 6 are fixedly connected to the support plate 7, further ensuring the stability of the support plate 7's sliding and preventing deviation, while also providing support and pushing force for the loitering munition.

[0015] In this utility model, the lifting component includes a first motor 4 installed in a mounting slot, a lead screw 3 coaxially connected to the output end of the first motor 4, and a guide rod in another mounting slot. Positioning plates 8 are provided on the lead screw 3 and the guide rod. Electric telescopic rods are hinged to both ends of the positioning plates 8, allowing for easy control of the elevation angle adjustment of the guide cylinder 5 via the lifting component. A clamp is bolted to the outer wall of the guide cylinder 5, and hinge seats are installed at both ends of the bottom of the clamp. The hinge seats are hinged to the extended ends of the electric telescopic rod. The pneumatic component includes a pneumatic pump 11 located on the outer wall of the mounting block. A pneumatic push rod is provided at the top of the pneumatic pump 11, and a movable pulley 13 is fixed to the top of the pneumatic push rod. A first fixed pulley 12 is provided at the top of the mounting block, and a second fixed pulley 14 is fixed to the bottom outer wall of the mounting block. A catapult rope 10 abuts between the first fixed pulley 12 and the second fixed pulley 14. Both ends of the catapult rope 10 are respectively fixed to the movable pulley 13 and the guide rod. On the column 6, pneumatic components facilitate the smooth movement of the movable pulley 13, thereby precisely controlling the sliding speed and acceleration of the bearing plate 7 and ensuring the controllability of the ejection force and speed. A damping spring 9 is installed at the top of the mounting block to buffer the ejection bearing plate 7. The damping spring 9 helps to reduce the collision impact between the bearing plate 7 and the top of the guide cylinder 5, reduce device vibration and noise, protect parts from damage, and extend the service life of the device. Four telescopic rods are fixedly connected to the bottom of the frame 1 inverted. Abutment plates are fixedly connected to the four telescopic rods. A rotating motor 16 is installed in the middle of the top of the abutment plate. A rotating threaded rod 17 is coaxially fixed to the extended end of the rotating motor 16. A fixing frame 15 is welded to the middle of the bottom of the frame 1. A threaded sleeve is provided on the fixing frame 15. The rotating threaded rod 17 is threadedly connected to the threaded sleeve. The rotating threaded rod 17 facilitates the abutment plate to be tightly pressed against the ground for fixing the device.

[0016] Working Principle: When using this utility model, firstly, each electrical component in this application is connected to the power supply. Then, the device moves on the ground via four wheels 2 at the bottom of the frame 1, facilitating transportation and deployment. After reaching the designated position, the telescopic rod at the bottom of the frame 1 is activated, causing the abutment plate to tightly contact the ground. The rotating motor 16 drives the rotating threaded rod 17 to rotate, causing the threaded sleeve to move on the fixed frame 15, thereby adjusting the support force of the abutment plate and achieving stable fixation of the device. Next, the first motor 4 in the lifting component drives the lead screw 3 to rotate, causing the positioning plate 8 to move up and down along the lead screw 3 and the guide rod. The electric telescopic rods at both ends of the positioning plate 8 are connected to the clamps on the outer wall of the guide cylinder 5 via hinge seats. When the electric telescopic rods extend and retract, they can push the guide cylinder 5 to rotate around the rotating axis, thereby adjusting the launch angle to adapt to different launch requirements. Then, after the pneumatic pump 11 is started, it pushes the movable pulley 13 upward via the pneumatic push rod. At this time, the ejection rope 10 passes over the first fixed pulley 12 and the second fixed pulley 13. Two fixed pulleys 14 form a pulley block structure. When the movable pulley 13 moves upward, the ejection rope 10 is tightened, thereby applying an upward pulling force to the guide posts 6 and the support plate 7 connected to both ends of the ejection rope 10. The support plate 7 is used to fix the loitering munition, and the guide posts 6 on both sides are inserted into the guide cylinder 5 to limit and guide, ensuring stability during ejection. When the pneumatic pump 11 drives the movable pulley 13 to move upward, the ejection rope 10 amplifies the pulling force through the pulley block, quickly pulling the support plate 7 upward along the guide cylinder 5. The sliding motion allows the loitering munition to gain initial launch velocity. Finally, when the support plate 7 reaches the top of the guide cylinder 5, the damping spring 9 inside the mounting block acts as a buffer to prevent the support plate 7 from colliding hard with the guide cylinder 5, thus protecting the device structure. After the launch is completed, the pneumatic pump 11 depressurizes, and the movable pulley 13 descends under the action of gravity or the reset mechanism, driving the launch rope 10 to retract. The support plate 7 falls back to the initial position along the guide cylinder 5, ready for the next launch. This concludes the use of the pneumatic launch device for the loitering munition.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
