Description

Technical Field

[0001] The present invention relates to the technical field of airborne airdrop, and relates to an airdrop self-falling buffer airbag installation system. Background Art

[0002] With the development of various large-scale and high-performance transport aircraft, air transportation and airdrop have become increasingly prominent in the status and role of modern warfare, and the combat strike method of heavy airdrop has also been paid more attention. The airdrop operation of a whole formation of combat vehicles is of great significance for suppressing the enemy's firepower and making a beachhead assault, and to a certain extent reflects the level of informationization and three-dimensional combat of the military. During the landing process of combat vehicle airdrop, ensuring that the combat vehicle equipment lands smoothly and its functional performance is not damaged or affected is a prerequisite for it to be able to be put into combat in time and play its effectiveness. If the landing overload of the combat vehicle exceeds the limit value that the vehicle body itself and the internal electronic equipment can withstand during airdrop landing, it will cause damage to the combat vehicle and electronic equipment and unable to play its combat performance. Therefore, it is very necessary to take load reduction measures during combat vehicle airdrop.

[0003] In order to absorb energy and reduce load after the combat vehicle lands from airdrop, the most important current measure is to install a buffer airbag at the bottom of the combat vehicle, only with differences in aspects such as the shape of the airbag, the inflation method, the installation method and the release method. The inflation methods are mainly divided into active inflation and passive inflation. Each has its own characteristics when compared. The active inflation airbag has a better buffer effect because it has a larger contact area with the vehicle chassis and fits better. However, the installation time of the active inflation airbag is longer, and because it needs to be actively inflated by external equipment during airdrop, the inflation pressure must first break and release the restraint of the airbag at the bottom of the vehicle body, so there is a certain lack of reliability. In addition, it is easy to interfere with the combat vehicle during release after landing; while the passive inflation airbag can be directly installed at the bottom of the combat vehicle after being prepared on the ground in advance, saving the hanging time, the installation process is simple, the release is reliable and easy to implement, and it inflates by the self-falling method, with better reliability. Compared with the active inflation airbag, it has certain advantages both in the installation method and the release process.

[0004] However, in the prior art, there are always some problems in the installation and release of the passive inflation airbag, making it difficult to ensure the reliable release of the airbag before the combat vehicle lands during the descent process of combat vehicle airdrop, and unable to fully exert the buffer effect when the combat vehicle lands during the self-falling inflation process, so that the overload borne by the combat vehicle is not reduced to the lowest. Summary of the Invention

[0005] The purpose of the present invention is to provide an airdrop self-falling buffer airbag installation system with a simple connection structure and rapid release in view of the deficiencies of the prior art.

[0006] The technical solution adopted by the present invention is as follows: an air-dropped self-falling buffer airbag installation system, which includes a support frame, an installation frame body and a buffer airbag.

The plug board is fixed at one end of the pull pin steel wire rope, and the other end of the steel wire rope is connected to the sling above the air-dropped combat vehicle. The rear end of the transfer support supports the lap support at the front end of the slide plate. A bayonet is opened on the lap support at the front end of the slide plate, and a hook adapted to the bayonet is arranged at the rear end of the limit hook.

[0008] According to the above solution, the support frame includes a front beam and a rear beam respectively arranged at the front and rear ends of the air-dropped combat vehicle, and several longitudinal beams arranged in parallel and connecting the front and rear beams. The length direction of the longitudinal beam is consistent with the driving direction of the air-dropped combat vehicle. The upper part of the buffer airbag is connected to the longitudinal beam. The clamping mechanism is installed on both sides of the front beam.

[0009] According to the above solution, support grooves facing forward are arranged on both sides of the rear beam, and the rear end of the slide plate is installed in the support groove through a lap support.

[0010] According to the above solution, both ends of the longitudinal beam are respectively lapped on the front beam and the rear beam, and are limited and fixed through a plug pin.

[0011] According to the above solution, there are four longitudinal beams, with one on each side and two in the middle. One sleeve is arranged on each of the left and right sides of the upper part of each buffer airbag, and the sleeves respectively pass through the side and middle longitudinal beams.

[0012] According to the above solution, the bottom plate structure includes several square bottom plates and several connecting bearings. The bottom plates are arranged in an array and are arranged between two slide plates. Four adjacent bottom plates are connected through a central connecting bearing and bolts. For the two bottom plates located on both sides, their outer side edges are connected to the slide plates through bolts. One buffer airbag is correspondingly installed on each bottom plate. The lower part of the buffer airbag is connected to a connecting rod arranged at the edge of the bottom plate through a circumferentially arranged rope loop, and the rope loops on two adjacent buffer airbags are sleeved.

[0013] According to the above solution, the bottom plate structure includes 8 bottom plates and 5 connecting bearings. The bottom plate as a whole is rectangular in structure, arranged in 2 rows and 4 columns. An inflation hole communicating with the inside of the buffer airbag is opened at the center of the bottom plate; one connecting bearing is used to connect the two bottom plates at the front end / rear end.

[0014] According to the above solution, the buffer airbag is in a three-dimensional square structure after inflation.

[0015] The beneficial effects of the present invention are as follows: For the buffer airbag installation system of the present invention, the installation process is simple and fast, greatly reducing the preparation time of the airdrop system.

[0025] Preferably, as Figure 4 shown, the clamping mechanism includes a transfer support 5 and a limit hook 6 installed at the front end of the support frame. The transfer support 5 and the limit hook 6 are coaxially assembled and can rotate around the axis. Slots are provided at the front ends of both the transfer support 5 and the limit hook 6. The slots are adapted to a plug board 9. The plug board 9 is inserted into the slots to limit the transfer support 5 and the limit hook 6. One end of the plug board 9 is fixed to one end of a pull pin wire rope 10, and the other end of the wire rope is connected to a sling 11 above the air-dropped combat vehicle. The rear end of the transfer support 5 supports a lap support 14 at the front end of a slide plate 13. A bayonet is provided on the lap support 14 at the front end of the slide plate 13, and a hook adapted to the bayonet is provided at the rear end of the limit hook 6. When the plug board 9 is inserted into the slots of the transfer support 5 and the limit hook 6, the transfer support 5 and the limit hook 6 are limited, and the rear end of the transfer support 5 is horizontal. When the plug board 9 is pulled out of the slots, the front end of the transfer support 5 rotates downward around the axis, and the lap support 14 falls under its own gravity, and the bayonet on the lap support 14 is disengaged from the hook on the limit hook 6.

[0026] Preferably, the mounting frame body includes a slide plate 13 and a bottom plate structure. There are two groups of slide plates 13, which are respectively arranged on both sides. The length direction of the slide plate 13 is consistent with the driving direction of the air-dropped combat vehicle. The bottom plate structure is installed between the two slide plates 13. The lower part of the buffer airbag 1 is connected to the bottom plate structure, and the upper part of the buffer airbag 1 is connected to the support frame.

[0027] Preferably, the bottom plate structure includes a plurality of square bottom plates 12 and a plurality of connecting bearings 16. The bottom plates 12 are arranged in an array and are provided between the two slide plates 13. Four adjacent bottom plates 12 are connected through a central connecting bearing 16 and bolts 15. For the two bottom plates 12 on both sides, their outer side edges are connected to the slide plates 13 through bolts 15. As Figure 3 shown, one buffer airbag 1 is correspondingly installed for each bottom plate 12. The lower part of the buffer airbag 1 is connected to a connecting rod provided at the edge of the bottom plate 12 through a circumferentially arranged rope loop 17, and the rope loops 17 on two adjacent buffer airbags 1 are sleeved.

[0028] In this embodiment, asFigure 2 As shown, the bottom plate structure includes 8 bottom plates 12 and 5 connecting bearings 16. The bottom plate 12 is integrally rectangular in structure and is arranged in 2 rows and 4 columns. An inflation hole communicating with the inside of the buffer airbag 1 is provided at the center of the bottom plate 12. One connecting bearing 16 is used to connect the two bottom plates 12 at the front end / rear end.

[0029] Preferably, the support frame includes a front beam 3 and a rear beam 4 respectively arranged at the front and rear ends of the air-dropped vehicle, and several longitudinal beams 2 arranged in parallel and connecting the front and rear beams 4. The length direction of the longitudinal beam 2 is consistent with the driving direction of the air-dropped vehicle. Sleeves 18 are provided on both sides of the upper part of each buffer airbag 1, and the sleeves 18 pass through the longitudinal beam 2. The clamping mechanism is installed on both sides of the front beam 3.

[0030] In this embodiment, as Figure 1 shown, there are four longitudinal beams 2, one on each side and two in the middle. One sleeve 18 is provided on each of the left and right sides of the upper part of each buffer airbag 1, and the sleeves 18 respectively pass through the side and middle longitudinal beams 2. The two ends of the longitudinal beam 2 are respectively lapped on the front beam 3 and the rear beam 4, and are respectively limited and fixed by pins 8 (the pins 8 pass through the longitudinal beam 2 and the front / rear beam 4).

[0031] Preferably, as Figure 4 shown, support grooves 7 facing forward are provided on both sides of the rear beam 4, and the rear end of the sliding plate 13 is installed in the support grooves 7 through a lapping support 14.

[0032] Before the vehicle is air-dropped, place the prepared buffer installation system directly below its bottom. The specific installation process is as follows: After folding the buffer airbag 1 neatly, compress it in the space between the support frame (formed by the longitudinal beam 2, the front beam 3 and the rear beam 4) and the installation frame (formed by the bottom plate 12 and the sliding plate 13). Then place the lapping supports 14 at the rear ends of the sliding plates 13 on both sides in the support grooves 7 on both sides of the rear beam 4. Rotate the adapter supports 5 on both sides of the front beam 3, place the lapping supports 14 at the front ends of the sliding plates 13 at the rear ends of the adapter supports 5, and cooperate with the hooks of the limit hooks 6 to limit and fix the lapping supports 14. Then insert the insertion plate 9 into the slot formed by the adapter support 5 and the limit hook 6 to prevent the adapter support 5 from rotating, and complete the locking of the sliding plate 13. Subsequently, complete the connection and installation of the front beam 3 with the front interface of the vehicle and the rear beam 4 with the rear interface of the vehicle respectively, and tie the pull-out pin steel wires 10 of the connection insertion plates 9 on both sides of the vehicle to the slings 11 above the vehicle respectively, and complete the ground preparation work of the entire buffer airbag installation system.

[0033] During the airdrop process, after the main parachute is inflated, the sling 11 above the combat vehicle is instantly straightened, and the two pull-pin steel wires 10 are quickly lifted, pulling out the plug plates 9 at the ends of the pull-pin steel wires 10 from both sides of the front beam 3 at the same time, releasing the limit on the adapter support 5; the adapter support 5 rotates downward, and then releases the restraint on the lap support 14 at the front end of the slide plate 13. The front end of the slide plate 13 moves downward under the action of its own gravity. As Figure 5 shown, the lap support 14 at the rear end of the slide plate 13 slides out of the support grooves 7 on both sides of the rear beam 4. Under the action of the self-weight of the slide plate 13 and the bottom plate 12, the buffer airbag 1 is immediately released and deployed and inflated during the descent of the combat vehicle. As Figure 6 shown.

[0034] The present invention installs the self-falling buffer airbag 1 at the bottom of the combat vehicle, ensuring the smooth release of the buffer airbag 1 after the combat vehicle lands during airdrop, solving the problems in the prior art that the buffer airbag 1 is difficult to be quickly and smoothly released during the airdrop process when it is connected and installed to the combat vehicle, and ensuring the overall coordinated linkage between the buffer airbags 1.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
