Description

Technical Field

[0001] This utility model relates to the field of aircraft maintenance, specifically to a special sheet metal transport device for aircraft maintenance. Background Technology

[0002] In the field of aircraft maintenance, the short-distance transportation of core materials such as aircraft metal skin and composite panels is one of the key aspects of maintenance operations. As an important component of the aircraft structure, these materials not only possess the characteristics of high precision and high value, but also exhibit significant dimensional variations (e.g., a single piece of metal skin can reach several square meters in area, while the thickness of composite panels varies from a few millimeters to tens of millimeters) and unique material properties (the surface of metal skin must be protected from scratches and damage, while composite panels have weak impact resistance and are prone to cracking). This places extremely high demands on the stability, protection, and adaptability during transportation. Currently, there are no dedicated transport vehicles designed for this type of sheet metal in aircraft maintenance scenarios. The industry generally uses general-purpose transport equipment such as ordinary flatbed carts, manual hydraulic forklifts, or simple support carts as temporary substitutes. However, these conventional tools have several technical shortcomings when adapting to the transportation needs of aircraft maintenance sheet metal, specifically in the following aspects: 1. Insufficient stability during transportation can easily lead to damage to the boards. Ordinary trolleys typically have a single planar load-bearing surface, lacking specific limiting and partitioning designs for sheet metal. When transporting metal skin, due to the large area and uneven weight distribution of the sheet metal, it is prone to lateral sliding or tilting during trolley movement (especially during turns, sudden stops, or slight ground bumps). This can not only cause friction scratches between the sheet metal surface and the trolley's metal frame, but also deformation due to the sheet metal edges colliding with trolley components. For composite material sheets, their shear strength is relatively low, and ordinary trolleys lack cushioning and protective structures. If the sheet metal comes into direct, rigid contact with the trolley during transportation, localized stress concentration caused by vibration can easily lead to fiber breakage within the sheet metal, directly affecting the safety of the aircraft structure after repair. Second, the space adaptability is poor, and it cannot meet the transportation needs of multi-specification boards. The specifications of sheet metal used in aircraft maintenance vary greatly. For example, the metal skin of different parts of the fuselage may have a size range of 1-5 meters in length and 0.5-2 meters in width, while composite material sheets may have irregular shapes (such as the curved leading edge of the wing). Ordinary trolleys have a fixed load-bearing area and no flexible partitioning or adjustment function. If multiple small-sized sheets are transported, the sheets are prone to stacking and compression, leading to wear on the surface coating. If large or irregular-shaped sheets are transported, the parts of the sheets that exceed the trolley's load-bearing capacity will be suspended in the air, which not only increases the difficulty of moving the trolley, but may also cause the trolley to tip over due to a shift in the center of gravity. Therefore, it cannot meet the needs of transporting multiple sizes of sheets at the same time in maintenance scenarios. Therefore, we propose a special sheet metal transport device for aircraft maintenance. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a special sheet metal transport device for aircraft maintenance, which can transport special sheet metal for aircraft maintenance smoothly and safely; when repairing different parts of the aircraft, the corresponding sheet metal can be directly taken out without being affected by the placement of other sheet metal; the height-limited areas on both sides of the trolley can hold most standard-sized sheet metal, while the middle area has unlimited height and can hold unconventional sheet metal.

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a special sheet metal transport device for aircraft maintenance, comprising a frame, a base plate, and partitions. The base plate is disposed at the bottom of the frame. The frame includes a base, a grid, and connecting beams. The base includes a bottom short crossbeam and a bottom long crossbeam. Six bottom short crossbeams are equidistantly disposed between the bottom long crossbeams. The frame has a cuboid structure. Six sets of grids are equidistantly disposed along the long side of this cuboid structure. Three sets of arched partitions are disposed on two adjacent bottom short crossbeams. The partitions are disposed on the grids. Five base plates are respectively placed between the six sets of grids.

[0005] Preferably, each set of grids consists of two outer grids, each outer grid including an upper short crossbeam and two sets of support columns. Multiple sets of partitions are evenly arranged between the upper and lower short crossbeams, and the two sets of support columns are respectively set on both sides of the multiple sets of partitions. An arched partition is set between two adjacent outer grids.

[0006] Preferably, the support column includes an inner support column and an outer support column. The lower ends of both the inner and outer support columns are connected to the base, the upper end of the outer support column is connected to the connecting beam, and the upper end of the inner support column is connected to the upper short crossbeam.

[0007] Preferably, the partition tube includes a straight partition tube and an arched partition tube, wherein the straight partition tube is uniformly and vertically arranged on the bottom short crossbeam, and the upper end of the straight partition tube is connected to the upper short crossbeam.

[0008] Preferably, the frame is provided with buckles and handles at both the front and back.

[0009] Preferably, the frame is provided with a caster wheel at the bottom.

[0010] Compared with the prior art, this utility model provides a special sheet metal transport device for aircraft maintenance, which has the following advantages: I. Ensure the stability and safety of sheet metal transportation and reduce the risk of loss. This specialized aircraft maintenance sheet metal transport vehicle enables the smooth and safe transport of specialized aircraft maintenance sheet metal such as metal skin and composite material sheets, fundamentally solving the problems of sheet metal swaying and collisions that easily occur during ordinary trolley transport. In terms of transport structure design, the vehicle uses a rationally arranged series of partitions (including straight and arched partitions) to divide and limit the sheet metal, combined with a linkage structure of buckles and safety ropes at the front and rear of the frame, effectively fixing the sheet metal's position and preventing it from being thrown out of the frame due to inertia during sudden stops or turns. Simultaneously, the frame is constructed from welded square tubing, with the base plate riveted to the foundation, resulting in high overall structural strength and stability, capable of withstanding the pressure of tens of kilograms of metal sheet metal, preventing sheet metal tilting and damage due to frame deformation during transport. This smooth and safe transport method significantly reduces the loss rate of aircraft maintenance sheet metal during short-distance transport, reduces additional procurement costs and maintenance delays caused by sheet metal damage, and ensures the stability of material supply for maintenance operations. II. Optimize the efficiency of material handling and placement to improve the convenience of maintenance operations. To address the need for rapid retrieval of specific sheet metal sections when repairing different parts of an aircraft, this specialized transport vehicle employs a scientifically designed spatial partitioning system, enabling "on-demand retrieval of sheet metal without interference." The frame features six equidistant grids along its long side, with five base plates positioned between these grids, forming independent sheet metal placement areas. Operators can pre-classify and place sheet metal according to its type and specifications required for the repair location within the designated partitions. When retrieving sheet metal for different locations (such as the fuselage side or wing), there's no need to move sheet metal from other areas; it can be directly retrieved from the target partition, completely eliminating the drawbacks of ordinary trolleys that require stacking and flipping for retrieval. Furthermore, handles at the front and rear of the frame allow operators to flexibly adjust the transport vehicle's position, pushing it directly to the vicinity of the repair station. This further shortens the distance for sheet metal retrieval, reduces the labor intensity of back-and-forth handling, and significantly improves the overall efficiency of maintenance operations. 3. Adaptable to the transportation of multi-size sheet materials, enhancing applicability to various scenarios. This specialized transport vehicle, through its differentiated structural design of "height restrictions on both sides + unlimited height in the middle," achieves full coverage of transporting both standard and extra-standard aircraft maintenance materials, significantly enhancing the tool's adaptability to various scenarios. The two sides of the transport vehicle's frame form a height-restricting structure with support columns (including inner and outer support columns) and a short crossbeam at the top. This height is suitable for most standard-sized metal skin and composite material panels, ensuring that standard materials will not sway or collide during transport due to exceeding height limits. The middle area of ​​the frame, without additional height restrictions, can accommodate extra-standard materials (such as extra-long wing skin and large composite substrates), solving the problem of ordinary trolleys being unable to transport extra-standard materials due to fixed height limitations. Simultaneously, the omnidirectional wheels at the bottom of the frame provide flexible steering capabilities, allowing for smooth movement even in the confined space of a hangar when transporting extra-standard materials, further enhancing the transport vehicle's applicability in different maintenance scenarios and meeting the diverse material transport needs during aircraft maintenance.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-2 A special sheet metal transport device for aircraft maintenance, with the following structure: I. Framework-related Structure (a) Framework 100 Frame 100 is the main support structure of the entire aircraft maintenance sheet metal transport vehicle. It has an overall rectangular shape and provides the installation and support foundation for other components of the transport vehicle. It consists of a base 110, a grille 170, and connecting beams 140, among other parts. These components work together to ensure the stability and load-bearing capacity of Frame 100. Frame 100 is welded from square tubing, a welding method that effectively enhances its structural strength and ensures it is not easily deformed during sheet metal transport. Furthermore, Frame 100 is equipped with buckles 150 and handles 160 at both the front and rear, and has 10 casters 400 at the bottom. These features not only provide excellent support but also facilitate transport and movement. (ii) Base 110 The base 110 is the bottom foundation structure of the frame 100, mainly serving to support and stabilize the entire transport vehicle, providing a support surface for the installation of other components at the bottom of the frame 100. It includes bottom short crossbeams 111 and bottom long crossbeams 112. Six bottom short crossbeams 111 are evenly spaced between the bottom long crossbeams 112. This even distribution ensures more uniform stress distribution on the base 110, improving its load-bearing capacity and thus guaranteeing the stability of the entire transport vehicle when transporting sheet metal. Furthermore, the base plate 200 is riveted to the base 110, and the lower end of the support column 120 is also connected to the base 110. Through these connections, the base 110 is tightly integrated with other components, collectively forming the bottom support system of the transport vehicle. (III) Bottom short crossbeam 111 The bottom short crossbeams 111 are an important component of the base 110, primarily used to enhance the lateral support capacity of the base 110 and provide installation positions for other components. There are six bottom short crossbeams 111, evenly spaced between the bottom long crossbeams 112. This arrangement not only makes the structure of the base 110 more stable but also rationally distributes the pressure borne by the base 110. Vertically evenly arranged straight partitions 310 are mounted on the bottom short crossbeams 111, with their lower ends connected to the bottom short crossbeams 111. Three sets of arched partitions 320 are also installed on adjacent bottom short crossbeams 111. Through their connection with these partition components, the bottom short crossbeams 111 further improve the internal structure of the transport vehicle, providing effective separation and support for the placement of sheet metal. (iv) Bottom long crossbeam 112 The bottom long crossbeam 112 is the main longitudinal support structure of the base 110. It works in conjunction with the bottom short crossbeams 111 to form the frame structure of the base 110, providing the main longitudinal load-bearing capacity for the base 110. It serves as the mounting base for the bottom short crossbeams 111. The six bottom short crossbeams 111 are evenly spaced between the bottom long crossbeams 112. The bottom long crossbeams 112, through their connection with the bottom short crossbeams 111, transfer the force of the base 110 to the entire frame 100, thereby ensuring the stability and load-bearing performance of the base 110 and even the entire transport vehicle, and ensuring that the base 110 will not be damaged due to excessive longitudinal force during the transportation of the sheet metal. (v) Support column 120 The support column 120 is a supporting component in the frame 100 used to connect the base 110 and the upper structure. It primarily serves as longitudinal support and connection, ensuring the stability and integrity of the upper and lower structures of the frame 100. It includes an inner support column 121 and an outer support column 122. The two sets of support columns 120 are respectively positioned on both sides of the multiple partition tubes 300. This arrangement allows the support columns 120 to provide some protection and limit the movement of the partition tubes 300, while also ensuring a more balanced stress distribution on the frame 100. The lower ends of both the inner support column 121 and the outer support column 122 are connected to the base 110. Through this connection, the support column 120 transfers the stress from the upper structure to the base 110, and then to the entire frame 100, ensuring the vertical stability of the frame 100. (vi) Inner support column 121 The inner support column 121 is a component of the support column 120, primarily used to connect the base 110 and the upper short crossbeam 130, providing vertical support to the upper short crossbeam 130 and ensuring its stability and load-bearing capacity. The lower end of the inner support column 121 is connected to the base 110, and the upper end is connected to the upper short crossbeam 130. This connection allows the inner support column 121 to transmit the pressure borne by the upper short crossbeam 130 to the base 110, and then through the base 110 to the entire frame 100. Simultaneously, the inner support column 121, in conjunction with the outer support column 122, is positioned on both sides of multiple sets of partitions 300, jointly protecting and limiting the partitions 300, further improving the internal support structure of the frame 100. (vii) Outer support column 122 The outer support column 122 is another component of the support column 120. It primarily connects the base 110 and the connecting beam 140, providing vertical support to the connecting beam 140 and ensuring its stability, thereby guaranteeing the overall structural integrity of the frame 100. The lower end of the outer support column 122 connects to the base 110, and the upper end connects to the connecting beam 140. Through this connection, the outer support column 122 transfers the force from the connecting beam 140 to the base 110, and then from the base 110 to the entire frame 100. Together with the inner support column 121, it forms the support column 120, providing support to the upper structure of the frame 100 from different positions, thus distributing the vertical force on the frame 100 and improving its overall load-bearing capacity. (viii) Upper short crossbeam 130 The upper short crossbeam 130 is an important component of the outer grid 171 in the grid 170. It primarily connects the inner support column 121 and the partition tubes 300, providing an upper mounting and support position for the partition tubes 300, and also enhancing the lateral support capacity of the grid 170. The upper short crossbeam 130 connects to the upper end of the inner support column 121 of the two sets of support columns 120. The upper end of the straight partition tubes 310 of the multiple sets of partition tubes 300 is connected to the upper short crossbeam 130, and the straight partition tubes 310 are inserted into the upper short crossbeam 130 without additional welding. This connection method ensures the stability of the connection between the straight partition tubes 310 and the upper short crossbeam 130 and simplifies the installation process. Through its connection with the inner support column 121 and the straight partition tubes 310, the upper short crossbeam 130 makes the structure of the grid 170 more stable, thus providing reliable support for the placement of the panels. (ix) Connecting beam 140 The connecting beam 140 is a transverse structure in the frame 100 used to connect the outer support column 122. Its main function is to connect and reinforce the side structure of the frame 100, improving the overall stability and deformation resistance of the frame 100. The connecting beam 140 connects to the upper end of the outer support column 122, and indirectly connects to the base 110 through the outer support column 122. This allows the connecting beam 140 to transfer the force on the side of the frame 100 to the base 110, and then to the entire frame 100. It works in conjunction with other components of the frame 100 to form the cuboid structure of the frame 100, ensuring that the frame 100 maintains its structural integrity and stability even when subjected to external impacts during transportation. (x) Buckle 150 Buckles 150 are located on the front and rear sides of frame 100, and their main function is to fasten safety ropes with hooks at both ends. During the transportation of sheet metal, when the transport vehicle stops suddenly, the sheet metal may easily be thrown out of frame 100 due to inertia. By fastening the safety rope to buckles 150, the safety rope can stop and limit the sheet metal, effectively preventing it from throwing out of frame 100 and ensuring the safety of the transportation process. The location of buckles 150 allows operators to quickly fasten and unfasten the safety rope, improving the convenience and safety of transportation operations. (xi) Handle 160 Handles 160 are also located on the front and rear sides of the frame 100, primarily providing gripping points for operators to push or pull the transport vehicle. The design of handles 160 takes into account operator comfort and ease of use, and their placement facilitates operation of the transport vehicle from different directions. Whether adjusting the direction of the transport vehicle in confined spaces or pushing it over long distances while transporting sheet metal, handles 160 provide convenience and improve transport efficiency. (xii) Grille 170 The grating 170 is an important partition and support structure inside the frame 100, mainly used to rationally divide the internal space of the frame 100, providing conditions for the classified placement and stable support of the panels. Six sets of gratings 170 are evenly spaced along the long side of the rectangular structure of the frame 100, with the five base plates 200 placed between the six sets of gratings 170. This layout allows for full utilization of the internal space of the transport vehicle and also provides some restraint to the base plates 200, preventing them from shifting during transportation. Each set of gratings 170 consists of two outer gratings 171. Through the structural cooperation of the outer gratings 171, the grating 170 provides installation positions for the partition tubes 300, further improving the internal support system of the transport vehicle. (xiii) External grille 171 The outer grille 171 is the basic unit constituting the grille 170. Each set of grilles 170 consists of two outer grilles 171, which mainly serve to separate, support, and install the partition tubes 300. The outer grille 171 includes an upper short crossbeam 130 and two sets of support columns 120. Multiple sets of partition tubes 300 are evenly arranged between the upper short crossbeam 130 and the bottom short crossbeam 111. The two sets of support columns 120 are respectively set on both sides of the multiple sets of partition tubes 300. This structural design allows the outer grille 171 to provide stable support and protection for the partition tubes 300. At the same time, it can also transfer the force to the entire frame 100 through the connection between the support columns 120 and the base 110 and the upper structure. In addition, the arched partition tube 320 is set between two adjacent outer grilles 171. The outer grille 171 provides a foundation for the installation and support of the arched partition tube 320, ensuring that the arched partition tube 320 can function properly. II. Base Plate Structure Base plate 200 The base plate 200 is the main component used to support the sheet metal. It is located at the bottom of the frame 100. Specifically, five base plates 200 are placed between six sets of grids 170. This placement method allows the base plates 200 to make full use of the internal space of the frame 100. At the same time, the grids 170 also limit the movement of the base plates 200, preventing them from shifting during transportation. The base plates 200 are riveted to the base 110. This riveting connection method has the advantages of strong connection, good sealing, and strong vibration resistance. It can ensure the stability of the connection between the base plates 200 and the base 110, ensuring that the base plates 200 will not separate from the base 110 due to the weight of the sheet metal or vibration during transportation. This ensures that the sheet metal can be stably placed on the base plates 200 for transportation. III. Related Structures of the Divider (a) 300mm partition tube The partition tube 300 is an important component inside the frame 100 used to separate and support the panels. Its main function is to further subdivide the internal space of the frame 100, preventing damage caused by collisions and friction between the panels during transportation. It also provides some support to the panels, ensuring their stability during transport. The partition tubes 300 are installed on the grating 170, specifically including two types: straight partition tubes 310 and arched partition tubes 320. The different types of partition tubes 300 differ in structure and installation method. They work together to achieve the function of separating and supporting the panels, providing suitable space for the transportation of panels of different specifications and types. (ii) Straight partition pipe 310 The straight partition tube 310 is a type of partition tube 300, mainly used to form a vertical partition and support structure inside the frame 100, providing vertical restraint and support for the panels. The straight partition tubes 310 are evenly and vertically arranged on the bottom short crossbeam 111, with their lower ends connected to the bottom short crossbeam 111 and their upper ends connected to the upper short crossbeam 130. The straight partition tubes 310 are inserted into the upper short crossbeam 130 without additional welding. This insertion connection method simplifies the installation process and ensures the stability of the connection between the straight partition tubes 310 and the upper and bottom short crossbeams 111. The evenly distributed straight partition tubes 310 make the partitions inside the frame 100 more uniform, providing a more stable and orderly placement space for the panels, effectively preventing tilting or displacement of the panels during transportation. (iii) Arched diaphragm 320 The arched partition tube 320 is another type of partition tube 300, also known as the bent tube 320. It is mainly used to form an arc-shaped partition and support between adjacent structures inside the frame 100, adapting to the placement requirements of plates of different shapes and sizes. Three sets of arched partition tubes 320 are installed on two adjacent bottom short crossbeams 111, positioned between two adjacent outer grilles 171. This installation position allows the arched partition tubes 320 to effectively supplement the partitioning function inside the frame 100, working in conjunction with the straight partition tubes 310 to further optimize the spatial layout inside the frame 100. Unlike the straight partition tubes 310, the arched partition tubes 320 still require welding after insertion. This welding connection method further enhances the robustness of the connection between the arched partition tubes 320 and other components, ensuring their stable partitioning and support functions during transportation. IV. Universal wheel structure 400 swivel wheels Ten casters 400 are installed at the bottom of the frame 100. Their main function is to enable the transport vehicle to move flexibly, allowing operators to adjust its position in different work scenarios and spaces, thus improving the convenience and flexibility of transportation. The ten casters 400 are evenly distributed at the bottom of the frame 100, ensuring more even force distribution on the transport vehicle and guaranteeing its stability during movement. This prevents the transport vehicle from tilting or becoming difficult to move due to uneven distribution of the casters 400. The casters 400 have 360-degree rotation capability. Operators can easily change the direction of movement of the transport vehicle by pushing or pulling the handle 160 on the frame 100. Whether on flat ground or slightly sloping ground, the casters 400 ensure smooth movement of the transport vehicle, facilitating the transportation of aircraft maintenance materials.

[0015] The structure is connected as follows: it includes a frame 100, a base plate 200, and partition tubes 300. The base plate 200 is located at the bottom of the frame 100. The frame 100 includes a base 110, a grid 170, and a connecting beam 140. The base 110 includes a bottom short crossbeam 111 and a bottom long crossbeam 112. The six bottom short crossbeams 111 are equally spaced between the bottom long crossbeams 112. The frame 100 has a cuboid structure. Six sets of grids 170 are equally spaced along the long side of this cuboid structure. Three sets of arched partition tubes 320 are set on two adjacent bottom short crossbeams 111. The partition tubes 320 are set on the grids 170. The five base plates 200 are respectively placed between the six sets of grids 170.

[0016] Each grid 170 consists of two outer grids 171. Each outer grid 171 includes an upper short crossbeam 130 and two sets of support columns 120. Multiple sets of partition tubes 300 are evenly arranged between the upper short crossbeam 130 and the bottom short crossbeam 111. The two sets of support columns 120 are respectively set on both sides of the multiple sets of partition tubes 300. An arched partition tube 320 is set between two adjacent outer grids 171.

[0017] The support column 120 includes an inner support column 121 and an outer support column 122. The lower ends of the inner support column 121 and the outer support column 122 are connected to the base 110. The upper end of the outer support column 122 is connected to the connecting beam 140. The upper end of the inner support column 121 is connected to the upper short crossbeam 130.

[0018] The partition tube 300 includes a straight partition tube 310 and an arched partition tube 320. The straight partition tube 310 is uniformly and vertically arranged on the bottom short crossbeam 111. The upper end of the straight partition tube 310 is connected to the upper short crossbeam 130. The straight partition tube 310 is inserted into the upper short crossbeam 130 without additional welding. The arched partition tube 320 still needs to be welded after insertion. The frame 100 is welded from square tubes. The base plate 200 is riveted to the base 110.

[0019] The frame 100 is equipped with buckles 150 and handles 160 at both the front and rear. The buckles can be used to fasten safety ropes with hooks at both ends to prevent the panels from being thrown out of the frame due to inertia in the event of an emergency stop.

[0020] The bottom of the frame 100 is provided with 10 casters 400.
