Description
Technical Field
[0001] The utility model relates to the technical field of special airdrop application, in particular to a guide device with an anti-following rotation function and used for a special airdrop cargo platform. Background Art
[0002] At present, when domestic IL-76 and X-20 transport aircraft airdrop cargo platforms (cargo), it is necessary to provide a guide device between the central rail of the aircraft and the airdrop cargo platform to facilitate the loading and unloading of the airdrop cargo platform on the aircraft and the straight line movement during airdrop.
[0003] The existing special airdrop cargo platforms in China do not have a unified guiding device, and do not have a dedicated interface with the aircraft's central rail for convenient installation and airdropping on transport aircraft. They are prone to jamming during installation and airdropping on IL-76 and X-20 transport aircraft. Summary of the invention
[0004] The utility model aims to provide a special guide device suitable for installing and airdropping special airdrop cargo platforms on IL-76 and X-20 aircraft, so as to realize the installation and airdrop requirements of special airdrop cargo platforms and ensure the stability and safety of special airdrop cargo platforms in the cabin.
[0005] The technical solution to achieve the purpose of the utility model is: a guide device with an anti-rotation function for a special airdrop cargo platform, the guide device includes a central axis rod, a pulley seat, a pulley, a pulley sleeve, an adjusting bolt, a quick-release pin, a spring, a large gasket, a washer and a nut; a half-moon-shaped cavity is designed inside the pulley seat body, a thread and a half-moon-shaped shaft rod are provided above the central axis rod, a threaded cavity is provided inside the lower part, and a circular boss is provided in the middle near the lower part. The pulley sleeve and the pulley are pressed and fitted on the boss on the middle axis rod, and the adjusting bolt thread is inserted into the middle axis rod. Connected to the threaded cavity below the center axis rod, the adjusting bolt is adjusted by rotating until the circular pin hole on the adjusting bolt wall is aligned with the pin hole on the center axis rod wall, and the quick-release pin is inserted into the pin hole. At this time, the center axis rod, pulley, pulley sleeve, adjusting bolt and quick-release pin form an assembly part. Then put the spring into the semi-moon-shaped cavity below the pulley seat body, and then insert the threaded end of the assembled assembly part shaft into the pulley seat cavity to expose the bolt head, insert a large gasket and washer into the bolt head, and then thread the nut and the center axis rod bolt head and tighten them.
[0006] Compared with the prior art, the utility model has the following significant advantages: (1) Guiding function: The guiding device rolls and slides along the lower edge of the aircraft's central rail through the pulley, so that the special airdrop cargo platform can move linearly along the aircraft's central rail, ensuring that the special airdrop cargo platform is stably pulled to the specified position without positional deviation. (2) Limiting function: The guiding device is clamped on the side and lower edges of the aircraft's central rail through the pulley, so that the special airdrop cargo platform itself can be limited up and down, left and right on the aircraft's central rail, thereby achieving the limitation in the carrier and providing the special airdrop cargo platform with the left and right upper and lower limiting functions. (3) Anti-following function: The guiding device realizes the anti-following function by clamping the half-moon-shaped central axis rod in the half-moon-shaped cavity of the pulley seat.

[0010] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0011] The utility model is used as a guide device for a special airdrop cargo platform for use on IL-76 and X-20 aircraft, and is used to provide an interface between the cargo platform and the central rail of the aircraft, complete the traction, installation and airdrop of the airdrop cargo platform on the aircraft, and has a function of preventing the guide device from rotating with the central rail of the aircraft during rotation. The guide device is used to provide an interface between the special airdrop cargo platform and the IL-76 and X-20 transport aircraft, complete the traction, installation and airdrop of the special airdrop cargo platform on the aircraft.
[0012] The guide device is mainly composed of a central axis rod 1, a pulley seat 2, a pulley 3, a pulley sleeve 4, an adjusting bolt 5, a quick release pin 6, a spring 7, a large gasket 8, a washer Ф10 and a nut M10, such as Figure 1The pulley seat 2 is designed with a half-moon shaped cavity inside the main body, the middle shaft 1 is designed with a thread and a half-moon shaped shaft, the lower part is designed with a threaded cavity, and the middle part is designed with a circular boss outside near the lower part. The pulley sleeve 4 and the pulley 3 are pressed and sleeved on the boss of the middle shaft 1. The adjusting bolt 5 is threadedly connected to the threaded cavity below the middle shaft 1. The adjusting bolt 5 is adjusted by rotating until the circular pin hole on the wall of the adjusting bolt 5 is aligned with the pin hole on the wall of the middle shaft 1, and a quick release pin 6 is inserted into the pin hole (inserting the quick release pin 6 can prevent the adjusting bolt 5 from being slid on the middle shaft 1). The middle shaft rod 1, pulley 3, pulley sleeve 4, adjusting bolt 5 and quick release pin 6 form an assembly. Then put the spring 7 into the semi-lunar cavity under the pulley seat 2 body. Then insert the threaded end of the assembly shaft rod just assembled into the 2 pulley seat cavity to expose the bolt head. Insert a large gasket 8 and a washer Ф10 into the bolt head. Then tighten the nut M10 and the bolt head of the middle shaft rod 1. At this time, the whole guide pulley is assembled. After assembly, the pulley 3 can rotate smoothly. The adjusting bolt 5 can be adjusted to rotate smoothly when the quick release pin 6 is pulled out. Guide device assembly instructions Figure 2 , full photo as Figure 3 shown.
