Description

Technical Field

[0001] The utility model relates to a columnar load throwing mechanism capable of suppressing shaking. Background Art

[0002] With the rapid development of science and technology, both in the civil and military fields, aircraft are often needed for transportation, such as drones, helicopters or rotorcraft, and flying drop accounts for an important part of aircraft transportation. At the same time, when the aircraft is dropped, columnar loads are often dropped. For example, when carrying out forest fire rescue, the thrown fire extinguishing bomb is a columnar body. The fire extinguishing bomb extinguishes the fire quickly and can extinguish the fire source in a short time. Using aircraft to throw fire extinguishing bombs to extinguish fires can not only quickly extinguish fires and reduce the damage of fires, but also reduce the risk of firefighting for firefighters.

[0003] In the military or civilian fields, helicopters or rotorcraft are often required to throw columnar loads, such as fire extinguishing bombs, backpacks, building materials, etc. In the authorized Chinese utility model patent "Announcement No.: CN219707316U, Name: A UAV-mounted Large-Size Load Thrower", the clamping block can clamp loads of different shapes through the setting of telescopic rods and reset springs. However, the above application uses springs and telescopic rods to clamp and fix the load, which can adapt to a small load range. Large loads are difficult to clamp, and small loads are unstable. At the same time, when the aircraft is flying, due to the influence of airflow, the load is easy to shake left and right, affecting the stability of the aircraft during flight.

[0054] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0055] Figures 1 to 9 The structure diagram of the embodiment of the utility model of the columnar load throwing mechanism with anti-swaying is shown. The columnar load throwing mechanism with anti-swaying includes a square tube 3, which is the installation platform of the entire throwing mechanism, the upper part of which is connected to the aircraft, and the columnar load is hoisted at the lower part;

[0056] A metal binding belt 1, wherein one end of the metal binding belt 1 is in contact with and connected to the locking structure 6;

[0057] Anti-sway forks 2, the bottom of the square tube 3 is detachably connected with a plurality of anti-sway forks 2 by bolts, and the anti-sway forks 2 can suppress the shaking of the columnar load during flight to ensure the stability of the flight;

[0058] A steering gear structure 5, both ends of the square tube 3 are detachably connected to the steering gear structure 5 by bolts;

[0059] A locking structure 6, wherein the bottom side of the square tube 3 is connected to a plurality of locking structures 6 distributed on the left and right sides;

[0060] The locking bar 7 is arranged in the inner cavity of the square tube 3, and the locking bar 7 is slidably connected to the locking structure 6.

[0061] In the present technical solution, the anti-sway fork 2 can be used to effectively prevent the load from swaying left and right due to the influence of airflow during flight, thereby increasing the stability of the aircraft's flight. The fixing bolt group 8 can be used to quickly replace the metal binding belts 1 of different diameters, making the application range of the casting mechanism wider, and columnar loads of different diameters can be stably clamped and fixed. At the same time, the lubrication component 602 can effectively reduce the friction between the locking bar 7 and the locking mechanism frame 601, making the casting of the columnar load smoother, faster and more accurate.

[0062] The two ends of the metal binding belt 1 are connected by a plurality of fixing bolt groups 8 .

[0063] In the present technical solution, the metal binding belts 1 of different diameters can be quickly replaced by using the fixing bolt group 8, so that the metal binding belts 1 can adapt to columnar loads of different diameters, making the application range of the throwing mechanism wider.

[0064] A cylindrical load can be a custom-made cylindrical box, or it can be cylindrical cargo or weapons.

[0065] Both ends of the square tube 3 are detachably connected with end covers 4 via a plurality of bolts.

[0066] In this technical solution, the end cover 4 can be used to isolate the external environment.

[0067] The steering gear structure 5 includes a steering gear body 501 , a steering gear rocker arm 502 and a pull rod 503 . The steering gear body 501 , the steering gear rocker arm 502 and the pull rod 503 are detachably connected in sequence by bolts.

[0068] The pull rod 503 is detachably connected to one end of the locking bar 7 via a bolt.

[0069] The locking structure 6 includes a locking mechanism frame 601, a lubrication assembly 602, a locking tongue 603 and a pin 604. The locking mechanism frame 601 is detachably connected to the square tube 3 via a plurality of bolts.

[0070] The lubrication assembly 602 is installed on the side of the lock mechanism frame 601, and the lubrication assembly 602 is in contact with the lock bar 7;

[0071] The locking tongue 603 is connected to the locking mechanism frame 601 via a pin shaft 604 , and the lower end of the locking tongue 603 is in contact with and connected to the metal binding belt 1 .

[0072] In this technical solution, the locking structure 6 is used to connect the columnar load to the aircraft.

[0073] The upper end of the locking tongue 603 is in contact with and connected to the locking bar 7 .

[0074] In this technical solution, in the locked state, the lock bar 7 is in contact and connected with the lock tongue 603 .

[0075] The cross section of the locking bar 7 at one end close to the pull rod 503 and the cross section of the pull rod 503 at one end away from the locking bar 7 are both U-shaped structures.

[0076] When in use, the servo body 501 rotates counterclockwise to drive the servo rocker arm 502 to rotate, and the servo rocker arm 502 drives the pull rod 503 to move leftward. At this time, the pull rod 503 can drive the locking bar 7 to slide horizontally to the left. After the locking bar 7 slides to a certain distance, it no longer contacts the locking tongue 603. At this time, the constraint on the locking tongue 603 disappears, and then the locking tongue 603 rotates downward around the pin 604 due to the principle of gravity. Subsequently, the locking tongue 603 no longer has a restraining effect on the metal binding belt 1, that is, after the locking bar 7 moves a distance, the locking bar 7, due to the existence of the movable mouth, makes the locking tongue 603 no longer in a self-locking state. At this time, the lower end of the locking tongue 603 is separated from the casting mechanism under the action of gravity due to the metal binding belt 1 and the columnar load, thereby realizing the casting of the columnar load, and the aircraft can be used for remote control casting of the columnar load or casting at a preset waypoint.

[0077] The lubrication assembly 602 includes an oil storage box 6021 and an oil-coated ball 6022;

[0078] The side of the lock mechanism frame 601 is provided with a through hole, and the oil storage box 6021 is installed on the wall of the through hole;

[0079] The top surface of the oil storage box 6021 is rotatably connected with a plurality of oil-coated balls 6022 , and the oil-coated balls 6022 are in contact with the bottom surface of the locking bar 7 .

[0080] In the present technical solution, the lubrication component 602 can be used to reduce the friction force generated by the left and right sliding of the lock bar 7, thereby reducing wear and extending the service life.

[0081] The inner wall of the oil storage box 6021 is fixedly connected to a fixed partition plate 6023, and the top of the fixed partition plate 6023 is connected to an oiling cotton block 6024, and the oiling cotton block 6024 is in contact with the oiling ball 6022;

[0082] A plurality of oiling cotton core strips 6025 are connected to the bottom of the oiling cotton block 6024 , and the lower ends of the oiling cotton core strips 6025 are connected through the fixed partition plate 6023 and extend to the bottom of the inner cavity of the oil storage box 6021 .

[0083] In the present technical solution, the lubricating oil can be attracted to the oiled cotton block 6024 by utilizing the oiled cotton core strip 6025 .

[0084] When the locking bar 7 moves, the oiled ball 6022 rotates, making the movement of the locking bar 7 smoother. At the same time, when the oiled ball 6022 rotates, the oiled cotton block 6024 and the oiled cotton core strip 6025 can brush lubricating oil on the surface of the oiled ball 6022, which not only makes the rotation of the oiled ball 6022 smoother, but also can further reduce the friction between it and the locking bar 7, making the movement of the locking bar 7 smoother, thereby reducing wear and increasing service life.

[0085] In the present application, except for the oiled cotton block 6024 and the oiled cotton core strip 6025, all other parts are made of steel.

[0086] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
