Description

Technical Field

[0001] This utility model patent relates to the field of airdrop training, and in particular to a mobile heavy-duty airdrop material bundling operation line. Background Art

[0002] Heavy-duty airdrops are a crucial component of material airdrops. Before being loaded onto aircraft, these materials must be loaded onto a platform. These platforms then undergo a series of procedures, including center of gravity adjustment, bundling, parachute installation, and hoisting, to prepare for transfer. Currently, these processes are all performed in one location, resulting in low efficiency. Assembly lines offer a promising solution, allowing loading, center of gravity adjustment, bundling, and hoisting to be completed at different locations along the line.

[0033] The mobile heavy-loaded airdrop material bundling operation line of this embodiment includes multiple central guide rail assemblies, multiple track units symmetrically arranged along the central guide rail assemblies, and multiple transverse connecting mechanisms. Adjacent central guide rail assemblies and adjacent track units are detachably connected through corresponding transverse connecting mechanisms. Specifically, the U-shaped support frame includes a bottom connecting plate and side panels on both sides. The slots at the front ends of the side panels are plugged and fixed with the plugs at the rear ends of the side panels of the adjacent track units. The first card slots of the side panels are card-engaged with the second card slots of the U-shaped connector. The depth of the first card slots is less than the height of the vertical plate and the distance from the bottom of the second card slots to the upper surface of the bottom plate of the U-shaped connector is less than or The U-shaped connector is fixed to each other in the horizontal and front-to-back directions, and the third and fourth slots of the central guide rail assembly are engaged with each other, and the central guide rail assembly and the U-shaped connector are fixed to each other in the horizontal and front-to-back directions. The guide wheel in the middle of the bottom of the airdrop cargo platform cooperates with the two side guides of the central guide rail assembly, and the roller grooves on both sides of the bottom of the airdrop cargo platform roll with the track units arranged symmetrically on the left and right. The loading of the airdrop cargo platform, adjustment of the center of gravity, and tying and lifting are completed at different positions. The disassembly and arrangement of the mobile heavy-duty airdrop material bundling operation line are very flexible.

[0034] Horizontal retaining edges 14 are provided on both sides of the bottom of the central guide rail assembly to increase the ground support area of the central guide rail assembly. The thickness of the horizontal retaining edges is equal to the thickness of the bottom plate of the U-shaped connector. The vertical distance between the step structure and the bottom of the central guide rail assembly is equal to the thickness of the bottom plate of the U-shaped connector. The vertical distance between the bottom surface of the front and rear ends of the side panels and the bottom surface of the side panels is equal to the thickness of the bottom plate of the U-shaped connector.

[0036] Example 2

[0037] Different from Example 1, Figure 5-Figure 7As shown, the transverse connection mechanism also includes at least one vertical positioning unit. In this embodiment, there is only one vertical positioning unit. Other embodiments may also include one vertical positioning unit on each side of the central guide rail assembly. The vertical positioning unit comprises a horizontal positioning plate 25 fixed to one side of the front bottom of the central guide rail assembly and a locking structure located in the middle of the U-shaped connector. The locking structure includes guide slots 18 provided on each of the two vertical plates, an "X"-shaped slide plate 19 that cooperates with the guide slots, and an elastic pressure member fixed at the angle between the two vertical plates and the bottom plate. The "X"-shaped slide plate and the bottom plate form a positioning slot 26 that snaps into place with the horizontal positioning plate. The elastic pressure member, located behind the "X"-shaped slide plate, comprises a spring sleeve 21 welded to the angle between the vertical plate and the bottom plate, a compression spring contained within the spring sleeve, and a push rod 20 located at the outer end of the compression spring. The push rod presses against the rear end of the "X"-shaped slide plate. A lever or pull plate, in this embodiment, is fixed to the top of the "X"-shaped slide plate to facilitate pushing and pulling the "X"-shaped slide plate. A detachable positioning block 24 is installed at the portion where the outer end of the X-shaped slide plate 19 cooperates with the guide groove 18 through a bolt 22.

[0038] The transverse connecting mechanism has a vertical positioning unit. After the central guide rail assembly is clamped on the transverse connecting mechanism, the elastic top pressure piece pushes the X-shaped slide plate to move along the guide groove and clamp the horizontal positioning plate, so that the central guide rail assembly remains stable in the vertical direction.

[0039] Example 3

[0040] Different from the above embodiment, Figure 8-Figure 9 As shown, the vertical positioning unit includes an end plate 27 fixed to the front end of the central guide rail assembly and a positioning structure fixed to the middle of the U-shaped connector. The positioning structure includes a fixing plate 28 welded and fixed along the longitudinal direction of the U-shaped connector 10 and at least one positioning pin 29 inserted and fixed in the fixing plate. In this embodiment, two positioning pins are provided, and the ends of the positioning pins extend out of the fixing plate to form positioning plugs 30. The end plates have positioning holes 31 that mate with the positioning plugs. To facilitate installation, a matching gap is provided between the positioning holes and the positioning plugs. The positioning pins are dumbbell-shaped, with the middle portion clamped and fixed in the fixing plate. The positioning plugs at both ends include a columnar portion and a tapered portion connected to the columnar portion, further facilitating the insertion of the positioning plugs into the positioning holes.

[0041] During installation, the tapered portion of the positioning plug is inserted into the positioning hole, and the third slot is then snapped into the corresponding fourth slot. Using the gap between the third and fourth slots in the front-to-back direction, the plug is pushed forward slightly to insert the columnar portion of the positioning plug into the positioning hole, completing the installation. The vertical positioning unit ensures vertical stability of the central guide rail assembly.
