Description

Technical Field

[0002] In order to ensure the safe landing of the airdrop vehicle within the predetermined overload range during heavy airdrop, a cushioning airbag device is required to cushion the impact and avoid damage to the airdrop vehicle. Figure 1 As shown, the existing heavy-duty airdrop cushioning airbag device generally includes a bottom plate 100, a top plate 110 and a cushioning airbag 120 whose bottom and bottom are respectively connected to the bottom plate 100 and the top plate 110, the bottom plate 100 is provided with at least two air inlets 130 connected to the cushioning airbag 120, and at least one exhaust port 140 is respectively provided at both ends of the cushioning airbag 120. When the heavy-duty airdrop cushioning device lands, external gas enters the cushioning airbag 120 through the air inlet 130 and is discharged through the exhaust port 140 to realize the cushioning function.

[0003] However, existing heavy-duty airdrop cushioning airbags are often designed with redundancy to avoid impact damage to airdropped vehicles. After the cushioning efficiency of the airbags is improved, the airdropped vehicle will often be overturned during the compression process of the airbags when the vehicle lands sideways due to the uncontrollable landing posture, which will have a significant impact on the cushioning efficiency and cause the airdrop mission to fail.

[0033] like Figure 2 and Figure 3 As shown, the embodiment of the present application provides a self-adjusting device for the pressure inside a lateral landing cushion airbag of a heavy-duty airdrop, which includes a bottom plate 100, a top plate 110, a cushion airbag 120 whose bottom and bottom are respectively connected to the bottom plate 100 and the top plate 110, and a partition cloth 150 arranged in the cushion airbag 120, the bottom plate 100 is provided with two air inlets 130 connected to the cushion airbag 120, and both side walls of the cushion airbag 120 are respectively provided with an exhaust port 140, the partition cloth 150 divides the cushion airbag 120 into a left airbag 160 and a right airbag 170, the left airbag 160 and the right airbag 170 are respectively connected to an air inlet 130 and an exhaust port 140, a connecting port 180 is provided on the partition cloth 150, and a valve linkage mechanism 200 is respectively connected to the connecting port 180 and the two exhaust ports 140;

[0034] The valve linkage mechanism 200 includes a door frame 210 provided on the corresponding communication port 180 or the exhaust port 140, a valve shaft 220 rotatably connected to the door frame 210, a valve 230 connected to the valve shaft 220, a bolt shaft 240 connected to the door frame 210, two valve bolts 290 rotatably connected to both ends of the bolt shaft 240, two tension springs 250 one end of which is connected to the door frame 210, two linkage steel cables 260, a steel cable swing seat 270 corresponding to the linkage steel cables 260, and a steel cable mounting seat 280 corresponding to the steel cable swing seat 270. When the valve 230 is subjected to force, it rotates around the valve shaft 220 to open the corresponding communication port 180 or the exhaust port 140. The other ends of the two tension springs 250 are respectively connected to one end of the two valve bolts 290, and the other ends of the two valve bolts 290 are respectively connected to one end of the two valve bolts 290. Connect one end of two linkage steel cables 260, the bottom end of each steel cable swing seat 270 is connected to one end of the corresponding steel cable mounting seat 280, the other ends of the two linkage steel cables 260 slide through the top of the corresponding steel cable swing seat 270 and are connected to the other end of the corresponding steel cable mounting seat 280, each steel cable swing seat 270 is arranged vertically with the corresponding steel cable mounting seat 280, the steel cable swing seat 270 and the corresponding steel cable mounting seat 280 connected thereto and one end of the corresponding linkage steel cable 260 form a right triangle; the two steel cable mounting seats 280 of the valve linkage mechanism 200 corresponding to the communication port 180 are respectively connected to the bottom plate 100 on both sides of the partition cloth 150, and the two steel cable mounting seats 280 of the valve linkage mechanism 200 corresponding to the exhaust port 140 are respectively connected to the top plate 110 on both sides of the cushioning airbag 120;

[0035] When the top plate 110 is tilted toward one side relative to the bottom plate 100, the partition cloth 150 drives a linkage steel cable 260 in the valve linkage mechanism 200 corresponding to the connecting port 180 to stretch the valve bolt 290 to rotate, so that the valve bolt 290 rotates to a vertical arrangement to block the corresponding valve 230 from rotating only in one direction toward the tilted side; when the top plate 110 is tilted toward one side relative to the bottom plate 100, the top plate 110 drives a linkage steel cable 260 in the valve linkage mechanism corresponding to the two exhaust ports 140 to stretch the valve bolt 290 to rotate, so that the valve bolt 290 rotates to a vertical arrangement to block and limit the corresponding valve 230 from rotating only in one direction away from the tilted side.

[0036] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the embodiment of the present application also provides a method for self-adjusting the pressure inside the lateral landing bag of a heavy-duty airdrop cushion airbag, which is performed using the above-mentioned self-adjusting device for the pressure inside the lateral landing bag of a heavy-duty airdrop cushion airbag, and includes the following steps:

[0037] The top plate 110 of the pressure self-adjusting device of the heavy equipment airdrop cushioning airbag lateral landing bag is installed at the bottom of the heavy equipment 300 to be airdropped, and the heavy equipment 300 is airdropped using a parachute 310 that provides a steady descent speed;

[0038] When the heavy equipment 300 lands, the pressure self-adjusting device of the heavy equipment airdrop cushion airbag lateral landing bag in the embodiment of the present application lands first. At this time, the pressure self-adjusting device of the heavy equipment airdrop cushion airbag lateral landing bag touches the ground at a certain horizontal speed and vertical speed. The bottom plate 100 first touches the ground and is immobilized due to friction, and the cushion airbag 120 and the top plate 110 are tilted to one side relative to the bottom plate 100. At this time, the heavy equipment 300 touches the ground. The buffer airbag 120 on the side has the risk of pushing the heavy equipment 300 to overturn. By adding a layer of partition cloth 150 in the middle of the buffer airbag 120 to separate the buffer airbag 120 into a left airbag 160 and a right airbag 170, when the top plate 110 is tilted to the right relative to the bottom plate 100, the partition cloth 150 drives the left linkage steel cable 260 in the valve linkage mechanism 200 corresponding to the communication port 180 to stretch the corresponding valve bolt 290 to rotate, so that the valve bolt 290 rotates to a vertical arrangement to prevent The corresponding valve 230 is blocked and cannot be rotated toward the left side and can only be rotated toward the right side, that is, the inclined side. At the same time, the top plate 110 drives a linkage cable 260 on the right side of the corresponding valve linkage mechanism of the two exhaust ports 140 to stretch the corresponding valve bolt 290 to rotate, so that the valve bolt 290 rotates to a vertical arrangement to block and limit the corresponding valve 230 from being able to rotate toward the right side and can only be rotated toward the left side, that is, away from the inclined side. Therefore, when the top plate 110 is tilted to one side relative to the bottom plate 100, the three corresponding valve linkage mechanisms are activated, so that the left airbag 160 can take in air from the bottom air inlet 130 and exhaust air from the exhaust port 140 normally, while the right airbag 170 cannot push the valve 230 on the connecting port 180 to rotate and open toward the left side, nor can it push the valve 230 on the exhaust port 140 to rotate and open toward the right side, thereby closing the inclined right airbag 170 to maintain pressure and improve the buffering performance of the inclined side of the buffer airbag 120, thereby avoiding the phenomenon of overturning and reloading equipment.

[0039] Among them, the two ends of the two tension springs 250 are respectively connected to the two valve bolts 290 and the door frame 210. When landing, the top plate 110 tilts toward the right side relative to the bottom plate 100, driving the linkage steel cable 260 to stretch the corresponding valve bolt 290. When the corresponding tension spring 250 is rotated, the corresponding tension spring 250 is stretched. When the landing is completed, the cushioning force of the cushioning airbag 120 resets the top plate 110 relative to the bottom plate 100, and the stretched tension spring 250 drives the valve bolt 290 to rotate in the opposite direction to reset and stop blocking the corresponding valve 230.

[0040] The present application also provides a method for self-adjusting the pressure inside a lateral landing bag of a heavy-duty airdrop cushion airbag, which is performed using the above-mentioned self-adjusting device for self-adjusting the pressure inside a lateral landing bag of a heavy-duty airdrop cushion airbag, and includes the following steps:

[0041] The bottom of the heavy equipment is fixed to the top surface of the top plate 110 of the self-adjusting device for the pressure inside the lateral landing bag of the heavy equipment airdrop cushion airbag for airdrop. During the airdrop, the heavy equipment and the self-adjusting device for the pressure inside the lateral landing bag of the heavy equipment airdrop cushion airbag descend and move to one side at a horizontal speed, so that when the top plate 110 is tilted to one side relative to the bottom plate 100, the corresponding valve linkage mechanism is driven to limit the corresponding valve 230 of the connecting port 180 to only be able to rotate one-way toward the tilted side and limit the corresponding valve 230 of the exhaust port 140 to only be able to rotate one-way toward the side away from the tilt, so that the gas enters the left airbag 160 and the right airbag 170 respectively through the air inlet 130, the air pressure in the left airbag 160 and the right airbag 170 increases, and the corresponding valve 230 is pushed to close the corresponding airbag close to the tilted side, so that the gas in the corresponding airbag away from the tilted side is discharged.

[0042] In other optional embodiments, such as Figure 7 As shown, the pressure self-adjusting device for the lateral landing cushion airbag of the heavy-duty airdrop can also be provided with two rows of air inlets 130 connecting the cushion airbags 120 on the base plate 100, and each row includes four air inlets 130. The side walls of the cushion airbags 120 are respectively provided with a row of four exhaust ports 140. The partition cloth 150 separates the cushion airbag 120 into a left airbag 160 and a right airbag 170. The left airbag 160 and the right airbag 170 are respectively connected to the four air inlets 130 and the four exhaust ports 140. The partition cloth 150 is provided with four connecting ports 180. The four connecting ports 180 and the eight exhaust ports 140 are respectively connected with valve linkage mechanisms 200. The two rows of air inlets 130, the four connecting ports 180 and the two rows of exhaust ports 140 are respectively arranged at intervals along the length direction of the cushion airbag 120.

[0043] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
