Description

Technical Field

[0001] The invention relates to the technical field of airdrop, and in particular to an airdrop landing simulation test device. Background Art

[0002] Airdrop refers to the technology of delivering items from the air to a designated area. It can be applied to both civilian and military fields, and plays an important role in natural disaster rescue and seizing the military initiative.

[0003] Airdrop simulation tests are of reference significance to real airdrop activities. Therefore, airdrop simulation tests need to be as close to the environment and parameters of real airdrops as possible. At present, the airdrop landing verification test capability is relatively weak, especially for heavy airdrop equipment. It only uses a crane to lift the equipment to a certain height and then release it, allowing it to complete the landing process by free fall. However, the real airdrop process is not the free fall process of an object. This only simulates the vertical falling speed of the airdrop equipment, and cannot verify that the equipment has both horizontal and vertical speed landing conditions. As a result, the test results are poorly equivalent to the actual airdrop, and it is difficult to meet the needs of heavy airdrop verification tests. Summary of the invention

[0004] In view of the above-mentioned technical problems existing in the prior art, an embodiment of the present invention provides an integrated airdrop landing simulation test device that can be quickly deployed.

[0032] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and well-known components are omitted.

[0033] like Figure 1 and Figure 2 As shown, an embodiment of the present invention discloses an airdrop landing simulation test device, which includes: a container 20, a crane arm 10, a pulley 30, a steel cable hoisting system 40, a telescopic system, and a traction winch 50.

[0034] The container 20 is configured as a structure that can be quickly deployed and folded, and the crane arm 10 is located in the container 20. In this way, when transportation is required, the container 20 is folded and the crane arm 10 is stored in the container 20, thereby facilitating transportation. When airdrop is required, the container 20 is quickly deployed. After deployment, the side panels of the container 20 serve as landing boards 22 for the airdrop objects 100.

[0035] The lower end of the boom 10 is mounted on a bottom plate 21 of a container 20 . After the container 20 is unfolded, the bottom plate 21 is stably placed on the ground of the test site, so that the bottom plate 21 serves as a supporting component of the boom 10 .

[0036] The boom 10 is configured to be able to extend and pitch, so that the boom 10 can control the airdrop height by extending and retracting, and the boom 10 can control the airdrop position by pitching. What is important is that by controlling the extension and retraction speed of the boom 10, the airdrop situation of the airdrop 100 at a vertical speed can be simulated. Specifically, a telescopic system is installed on the boom 10, and the telescopic system is used to control the extension and retraction of the boom 10. A steel cable hoisting system 40 is installed on the boom 10, and the steel cable of the steel cable hoisting system 40 passes around the top of the boom 10. The hook 41 at the end of the steel cable hoisting system 40 is used to hoist the airdrop 100, and the steel cable hoisting system 40 is also used to control the height of the airdrop 100. Preferably, the telescopic range of the boom 10 is 12-18m.

[0037] A pulley 30 is installed at the top of the boom 10, and the steel cable of the steel cable hoisting system 40 passes around the pulley 30. A slide rail is installed at the pulley 30 so that the pulley 30 can slide linearly. A traction winch 50 is installed at the root of the boom 10. The traction winch 50 drives and controls the pulley 30 to slide by telescopic means. When the pulley 30 slides, the airdrop 100 moves horizontally with the pulley 30. Therefore, the traction winch 50 drives the pulley 30 to drive the airdrop 100 to move horizontally to simulate an airdrop with a horizontal speed. Preferably, the linear sliding range of the pulley 30 is configured to be 1-2m.

[0038] Based on the above, it can be known that the airdrop of the airdrop object 100 having both vertical and horizontal velocities can be simulated by simultaneously extending and retracting the boom 10 and sliding the pulley 30 .

[0039] In some preferred embodiments, the boom 10 is configured to be able to pitch, and an angle plate is installed at the bottom of the boom 10, which is used to monitor the pitch angle of the boom 10. Preferably, the boom 10 is configured to be able to pitch within a range of -90° to 90° relative to the vertical direction.

[0040] In some preferred embodiments, the hook 41 of the wire rope hoisting system 40 is configured to be of a type and structure capable of controlled automatic release, so that the hook 41 can be controlled to release the airdrop 100 at a preset time.

[0041] In some preferred embodiments, an elastic buffer device is installed at the connection between the pulley 30 and the boom 10 , and the elastic buffer device is used to decelerate and buffer the moving pulley 30 to avoid vibration of the boom 10 .

[0042] In some preferred embodiments, a binding strap is disposed at the bottom of the container 20 . After the boom 10 is retracted and stored in the container 20 , the binding strap is used to bind the boom 10 , so as to limit the shaking of the boom 10 when being transported with the container 20 .

[0043] In some preferred embodiments, the bottom of the container 20 is provided with a retractable wheel hub. When simulating an airdrop, the wheel hub is retracted so that the container 20 is stably placed on the ground. During transportation, the wheel hub extends out of the bottom of the container 20 for easy towing.
