Description

Technical Field

[0001] This utility model relates to the field of helicopter technology, and more specifically, to a helicopter rapid loading vehicle. Background Technology

[0002] In the field of helicopter logistics support and material transportation, the loading efficiency and operational safety of cargo boxes directly affect mission execution capabilities. Traditional helicopter cargo box designs generally adopt non-standard structures to adapt to cabin space and item securing requirements: their bottoms are usually sloping to match the cabin support frame, and the side walls are curved to distribute stress and reduce space occupation.

[0003] However, cargo boxes typically weigh 30-50 kg, requiring 2-3 operators to work together to lift them to the helicopter door position, about 1 meter off the ground. This is physically demanding, especially in high-altitude or high-temperature environments, which can easily lead to operational errors. Furthermore, it is difficult to precisely control the cargo box's attitude when manually lifting it. The low coefficient of friction between its curved sidewalls and the internal rails makes it prone to slipping or jamming, resulting in repeated adjustments and time-consuming loading. The average loading time is 8-12 minutes. If the cargo box accidentally slips out of control, it may collide with the fuselage or ground equipment, causing property damage or even personal injury. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a helicopter rapid loading vehicle.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A helicopter rapid loading vehicle includes a manual hydraulic lifting vehicle. A lower manual adjustment mechanism is installed on the placement plate of the manual hydraulic lifting vehicle. An upper manual adjustment mechanism is installed above the lower manual adjustment mechanism. An upper plate is installed on the top of the upper manual adjustment mechanism. A support plate is connected to the upper plate through a support member. A support frame and an arc-shaped slide rail are installed on the support plate.

[0007] Furthermore, a splicing plate is provided on one side of the support plate.

[0008] Furthermore, the support frame includes a vertical plate with a base plate welded to its bottom and a support box at the top of the vertical plate. The support box has an arc-shaped surface on the side near the slide rail, and a number of rectangular holes are formed on the arc-shaped surface. A number of rotating shafts are provided inside the support box, and rotating rollers are rotatably connected to the rotating shafts. The arc-shaped sidewalls of the rotating rollers extend to the outside through the rectangular holes.

[0009] Furthermore, the arc-shaped surface of the support box is coaxially arranged with the arc-shaped slide rail.

[0010] Furthermore, the support member includes two hinge seats and an angle adjustment assembly, both of which are installed between the upper plate and the support plate.

[0021] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "aspect," or "specific example" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this invention.

[0026] In this specification, the illustrative expressions of the terms used do not necessarily refer to the same embodiments or examples. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0027] like Figures 1-4As shown, a helicopter rapid loading vehicle includes a manual hydraulic lift 100, which serves as the basic carrier of the loading vehicle and provides vertical lifting functionality to facilitate the raising of cargo boxes to the height required for helicopter loading. This manual hydraulic lift is an outsourced component; a HEAMI brand manual hydraulic lift can be purchased, with a maximum load capacity of 500 kg, a steel frame, and polyurethane casters.

[0028] Compared with existing technologies, traditional helicopter cargo box loading and unloading relies entirely on manpower. In contrast, this project uses a manual hydraulic lifting vehicle 100 as the basic carrier, which provides vertical lifting function, significantly reducing the burden on manpower and enabling the cargo box to be accurately lifted to the height required for helicopter loading, which is not available in existing technologies.

[0029] The manual hydraulic lifting vehicle has a lower manual adjustment mechanism 200 installed on the placement plate 101. An upper manual adjustment mechanism 300 is installed above the lower manual adjustment mechanism. An upper plate 301 is installed on the top of the upper manual adjustment mechanism. The upper plate is connected to a support plate 2 through a support member. The support plate serves as a support platform for the cargo box and its angle can be adjusted to accommodate cargo boxes of different shapes.

[0030] In existing technologies, horizontal adjustment is often difficult to achieve or has low precision. However, this invention achieves precise forward, backward, left, and right movement of the support plate in the horizontal plane through the combination of the lower manual adjustment mechanism 200 and the upper manual adjustment mechanism 300. This level of adjustment precision and convenience is difficult to achieve with existing technologies.

[0031] The support plate is equipped with a support frame and an arc-shaped slide rail 3. The upper and lower manual adjustment mechanisms allow the support plate to move horizontally (forward, backward, left, and right) via manual operation, enabling precise adjustment of the cargo box's position. The lower manual adjustment mechanism 200 allows for left and right movement, while the upper manual adjustment mechanism 300 allows for forward and backward movement.

[0032] Furthermore, a splicing plate 6 is provided on one side of the support plate.

[0033] Furthermore, the support frame includes a vertical plate 4, with a base plate 41 welded to its bottom. The base plate can be welded to the support plate. A support box 5 is provided at the top of the vertical plate. An arc-shaped surface 51 is formed on the side of the support box near the slide rail. Several rectangular holes 511 are formed on the arc-shaped surface. Several rotating shafts 521 are provided inside the support box. Rotating rollers 52 are rotatably connected to the rotating shafts. The arc-shaped sidewalls of the rotating rollers extend to the outside through the rectangular holes. This design allows the arc-shaped surface of the cargo box to contact the rotating rollers, facilitating movement.

[0034] Compared with the prior art, the support frame design in this case is more reasonable. The cooperation between the arc-shaped surface 51 of the support box 5 and the rotating roller 52 makes the arc-shaped surface of the cargo box contact the rotating roller, which greatly facilitates the movement of the cargo box and reduces frictional resistance. This is something that the simple support structure in the prior art cannot match.

[0035] In a more detailed design, the curved surface of the support box is coaxially aligned with the curved slide rail. This thoughtful design ensures the stability and smoothness of the cargo box during movement.

[0036] In at least one embodiment, the support member includes two hinge seats 11 and an angle adjustment assembly. Both the hinge seats and the angle adjustment assembly are installed between the upper plate and the support plate. The hinge seats are existing technology and have been widely used in daily life. They include a lower hinge plate 111, which is fixedly connected to the upper plate by bolts. A rotating shaft is installed between the two lower hinge plates. A connecting block 112 is provided at the bottom of the support plate. A rotating shaft hole is formed on the connecting block to accommodate the rotating shaft. The connecting block is installed on the rotating shaft. The angle adjustment assembly includes a lower connecting plate 13 and an upper connecting plate 12. A lower connecting plate is formed on the side wall of the upper plate. A rotating wheel 14 is rotatably connected to the lower connecting plate. A central threaded hole is formed in the center of the rotating wheel. A ball head bolt 15 is internally threaded into the central threaded hole. The bolt part of the ball head bolt is threaded into the central threaded hole. The ball head of the ball head bolt is inserted into the hexagonal hole of the upper connecting plate through a hexagonal prism pin 16. The upper connecting plate is fixedly connected to the support plate. By rotating the wheel, the ball head bolt is displaced relative to the wheel, thereby changing the angle of the support plate relative to the upper plate.

[0037] In at least one embodiment, the lower manual adjustment mechanism has the same structure as the upper manual adjustment mechanism. Their combined design enables the support plate to move horizontally in all directions, and when used with a manual hydraulic lifting vehicle, it allows for vertical movement of the support plate. This three-dimensional adjustment design makes the technical solution of this invention more flexible and adaptable during the loading and unloading process, meeting the loading and unloading needs of cargo boxes of different shapes and sizes.

[0038] The above manual adjustment mechanism will be used as an example for analysis.

[0039] The manual adjustment mechanism includes an upper housing 302, which includes an upper base plate 3021. A first bearing seat 305 and a second bearing seat 306 are located in the middle of the upper base plate. A lead screw 307 is installed between the first and second bearing seats. The end of the lead screw passes through a hole in the upper housing and is connected to a rocker wheel 308. A threaded sleeve 309 is threaded onto the lead screw, and the threaded sleeve is bolted to the bottom of the upper plate 301. The lead screw and threaded sleeve work together to convert the rotational motion of the lead screw into the linear motion of the threaded sleeve, thereby achieving precise movement of the upper plate 301. A guide assembly is provided on each side of the lead screw. Each guide assembly includes a slide rail 303, which is bolted to the upper base plate. A slider 304 slides on the slide rail and is bolted to the bottom of the upper plate 301. The upper plate can be moved along the lead screw by rotating the rocker wheel. The rocker wheel is made of aluminum alloy with a non-slip surface and is connected to the end of the lead screw via a flat key.

[0040] The upper manual adjustment mechanism and the lower manual adjustment mechanism move in different directions. Assuming that the upper manual adjustment mechanism can move the upper plate back and forth, then the lower manual adjustment mechanism can move the upper plate left and right.

[0041] In use, first place the cargo box on the splicing plate, then adjust its position so that the bottom of the cargo box slides into the curved slide rail while the side wall of the cargo box contacts the rotating roller of the supporting box. After this process is completed, the rotating wheel can be adjusted to change the angle of the cargo box.

[0042] Vertical lifting and lowering is achieved via a manual hydraulic lifting platform 100; horizontal movement (forward, backward, left, and right) is achieved via a lower manual adjustment mechanism 200 and an upper manual adjustment mechanism 300, aligning the cargo box with the cargo box push rail on the helicopter. The cargo box is then pushed along the cargo box push rail into the helicopter to complete the loading. During the pushing process, the rotating roller 52 rolls against the side wall of the cargo box, reducing frictional resistance.

[0043] Testing showed that the loading trailer has a maximum load capacity of 500 kg, meeting the loading requirements of helicopter cargo containers. During loading, the trailer remained stable without swaying or tilting, ensuring safe operation. A three-way adjustment mechanism allows operators to quickly and accurately adjust the position and angle of the cargo container, achieving docking with the helicopter cargo container's push rails. Testing also showed that the average loading time was reduced to less than one-third of the original time.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions in the above embodiments and specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
