Description

Technical Field

[0001] This utility model relates to a multifunctional storage and transportation support, and more particularly to a multifunctional storage and transportation support for a door frame wall panel with a U-shaped groove, belonging to the field of aircraft production and manufacturing process equipment design and manufacturing technology. Background Technology

[0002] Terminology Explanation:

[0003] 1) Aircraft components refer to the assembly parts of a certain part of the aircraft body during the manufacturing stage;

[0004] 2) Lifting equipment refers to specialized equipment used for lifting aircraft parts.

[0005] In the production of door frame panel components for passenger-to-freighter converted aircraft, the lower door frame panel is a U-shaped curved panel with grooves, with external dimensions of 6121mm × 1879mm and U-shaped opening dimensions of 3556mm × 850.9mm. In the current production process, the U-shaped door frame components are stored on horizontal storage racks. After the product is assembled, it is lifted through the lifting hole in the middle of the component into a packaging box for hoisting, packaging, and shipping.

[0006] Existing aircraft components are stored on wheeled brackets with horizontal upper surfaces. Due to gravity, the curved areas around the components are prone to deformation. Especially during the process of moving and transporting within the factory, the curved areas around the components move up and down slightly, which exacerbates the deformation of the curved surfaces. Furthermore, the opening size of the components at the U-shaped opening is also prone to tearing and deformation, resulting in deformation and damage to the components, which may lead to their scrapping.

[0007] Using existing brackets to store and transport lower door frame wall panels has the following disadvantages.

[0008] 1) Due to the U-shaped notch of the product, the existing storage racks are prone to deformation or even tearing of the product at the curved surface and opening during the storage and transportation of components. It is necessary to customize a special packaging box and its supporting base according to the shape of the aircraft parts to be shipped; the customized shape and size of the packaging box are irregular.

[0009] 2) To reduce the amount of deformation of parts, the existing storage racks are mainly used to store components, which has a relatively simple function and occupies a large area;

[0010] 3) Due to the irregular shape and uneven thickness of the components, under the existing storage method, the non-open U-shaped end of the components will sink under the influence of gravity during lifting, which can easily cause damage. Utility Model Content

[0011] The technical problem to be solved by this utility model is to provide a multifunctional storage and transportation bracket for door frame wall panels with U-shaped grooves that can effectively prevent deformation or even tearing of door frame wall panels during storage and transportation.

The support surface is formed by the contouring arc surfaces of each set of contouring support main support plates and each set of contouring support auxiliary support plates. The part of the door frame wall panel without the U-shaped groove is attached to the support surface formed by each set of contouring support main support plates, and the door frame wall panel below the U-shaped groove is attached to the support surface formed by each set of contouring support auxiliary support plates. The lower end of the door frame wall panel is supported on the limiting and fixing device.

[0019] Furthermore, the limiting and fixing device includes a supporting limiting component and a fixing component. At least the supporting limiting component is provided at the lower end of the secondary contouring support plate, and at least the fixing component is provided at the lower end of the main contouring support plate. During storage or riveting, the door frame wall panel with its lower end supported on the supporting limiting component is pressed onto the supporting surface by the fixing component.

The limiting and fixing device and the contour support device are then arranged on the frame in a mutually compatible manner. A support surface adapted to the shape of the door frame wall panel with a U-shaped groove is provided on the contour support device. Finally, during the storage, transportation, and riveting process of the door frame wall panel, the door frame wall panel with a U-shaped groove arranged on the support surface is detachably fixed to the multi-functional storage and transportation bracket by the limiting and fixing device. This changes the existing technology of directly storing arc-shaped door frame wall panels on a wheeled bracket with a horizontal surface. Instead, it uses a contour support device with a supporting surface for storage, thus effectively preventing deformation of the door frame wall panel or even tearing of the U-shaped groove during storage and transportation. Furthermore, by improving the frame and arranging the contour support device on the base in a way that adapts to the riveting position of the door frame wall panel through the frame's support mounting structure, the multifunctional storage and transportation bracket of this application can also have both good riveting and transportation functions.

[0027] like Figure 1 , Figure 2 as well as Figure 3 The illustration shows a multi-functional storage and transportation rack for door frame panels with U-shaped grooves, which effectively prevents deformation or even tearing of door frame panels during storage and transportation. The multi-functional storage and transportation rack includes a frame, a contouring support device, and a limiting and fixing device. The limiting and fixing device and the contouring support device are arranged on the frame in a mutually compatible manner. The contouring support device has a support surface adapted to the shape of the door frame panel with U-shaped grooves to be stored. During storage, transportation, and riveting of the door frame panel 1, the door frame panel with U-shaped grooves arranged on the support surface is detachably fixed to the multi-functional storage and transportation rack by the limiting and fixing device. The technical solution provided in this application involves setting up a multi-functional storage and transportation bracket including a frame, a contouring support device, and a limiting and fixing device. The limiting and fixing device and the contouring support device are then arranged on the frame in a mutually compatible manner. A support surface adapted to the shape of the door frame panel with a U-shaped groove is provided on the contouring support device. Finally, during the storage, transportation, and riveting process of the door frame panel, the door frame panel with the U-shaped groove, arranged on the support surface, is detachably fixed to the multi-functional storage and transportation bracket by the limiting and fixing device. This changes the existing technology of directly storing curved door frame panels on a horizontally surfaced wheeled bracket. Instead, it uses a contouring support device with a supporting surface for storage, effectively preventing deformation of the door frame panel or even tearing of the U-shaped groove during storage and transportation.

[0028] Furthermore, considering the actual conditions of the production site, and to facilitate manufacturing and subsequent use, this application further improves the chassis. The contouring support device is arranged on the base in a way that adapts to the riveting position of the door frame panel 1 via the chassis's support mounting structure. This also allows the multi-functional storage and transportation bracket of this application to simultaneously possess excellent riveting and transportation functions. Specifically, the chassis of this application includes a base 2 and a support mounting structure. The contouring support device is arranged on the base 2 in a way that adapts to the riveting position of the door frame panel 1 via the support mounting structure. The limiting and fixing device is arranged on the base 2 in a way that adapts to the position of the contouring support device. A moving and traveling mechanism is provided on the bottom surface of the base 2. In a preferred embodiment, at least the base 2 is a truss welded from square tubes or square steel. The contouring support device is arranged on the truss through a support installation structure. The limiting and fixing device is arranged on the truss in accordance with the position of the contouring support device. At least one set of telescopic support limiting devices is also provided at each end of the truss along its length. The sets of walking wheels 3 constituting the moving walking mechanism are symmetrically arranged on the bottom surface of the truss. During the storage or riveting of the door frame wall panel 1, the sets of walking wheels 3 at the positions corresponding to the positions of the telescopic support limiting devices are lifted off the ground with the cooperation of the telescopic support limiting devices. Each telescopic support limiting device includes a support foot 4, a set of threaded lifting rods 5, and a crank 6. The support foot 4 is movably arranged at the lower end of the threaded lifting rods 5, and the crank 6 is movably arranged at the upper end of the threaded lifting rods 5. The threaded lifting rods 5 are fixed vertically through their middle at the corresponding position on the truss. During the storage or riveting of the door frame wall panel 1, the traveling wheels 3 on the truss corresponding to the positions of each telescopic support limiting device are lifted off the ground by the support foot 4 in cooperation with the threaded lifting rods 5 and the crank 6.

Each set of contouring support main support plates 7 is arranged on the base 2 through the main support frames 9, and each set of contouring support auxiliary support plates 8 is arranged on the base 2 through the auxiliary support frames 10. The support surface is formed by the contouring arc surfaces of each set of contouring support main support plates 7 and each set of contouring support auxiliary support plates 8. The part of the door frame wall panel 1 without the U-shaped groove is attached to the support surface formed by each set of contouring support main support plates 7, and the door frame wall panel 1 below the U-shaped groove is attached to the support surface formed by each set of contouring support auxiliary support plates 8. The lower end of the door frame wall panel 1 is supported on the limiting and fixing device. At this time, each group of contour support main support plate 7 is composed of a main contour support plate, and each contour support secondary support plate 8 is composed of a secondary contour support plate. Each main contour support plate is fixedly mounted on the main support frame 9 and truss in accordance with the position of the part of the door frame wall panel 1 without the U-shaped groove. Each secondary contour support plate is fixedly mounted on the secondary support frame 10 and truss in accordance with the position of the door frame wall panel 1 below the U-shaped groove. More specifically, the main support frame 9 of this application is a truss-type main support frame welded from square tubes or square steel, and the secondary support frame 10 is a truss-type secondary support frame welded from square tubes or square steel. The truss-type main support frame is arranged along the length direction at the rear edge of the base 2, and the truss-type secondary support frame is arranged along the length direction at the middle of the front part of the base. The main contour support plates and the secondary contour support plates arranged by the truss-type main support frame and the truss-type secondary support frame in cooperation with the base 2 constitute the support surface for supporting the door frame wall panel 1.

[0030] As another major improvement in this application, in order to adapt to the structure of the contour support device, the limiting and fixing device of this application includes a supporting limiting component and a fixing component. At least the supporting limiting component is provided at the lower end of the secondary contour support plate, and at least the fixing component is provided at the lower end of the main contour support plate. During storage or riveting, the door frame wall panel 1, which is supported on the supporting limiting component at the lower end, is pressed onto the support surface by the fixing component. The preferred method is that the support limiting assembly includes multiple sets of support plates 12 containing support blocks 11, with the number of support plates being equal to the number of secondary contour support plates. Each support block 11 has a buffer 13 on its top support surface. Each secondary contour support plate has a buffer 13 arranged at its lower end through the support plate 12 in cooperation with the support block 11. The fixing assembly includes at least two sets of clamps 14 and multiple mounting plates 15 with the number of clamps 14 being equal to the number of clamps 14. At least one set of clamps 14 is arranged at the lower end of the two outermost main contour support plates through the mounting plates 15. During storage or riveting, the lower end of the door frame wall panel (1) is abutted against the support block 11 through the buffer 13. At least the two sides of the lower end of the door frame wall panel are pressed against the support surface through each set of clamps 14.

[0031] Meanwhile, to facilitate movement during transport, the multifunctional storage and transport support described in this application also includes two sets of traction devices. Each traction device includes a reinforcing locking frame 16 and a traction connecting frame 17. A traction connecting frame 17 is hinged to each end of the base 2 along the length direction. A reinforcing locking frame 16 is arranged on the base 2 at the position corresponding to each traction connecting frame 17. During the movement and transport process, the base 2 is connected to the external drive device through the traction connecting frame 17. During the storage or riveting process, the traction connecting frame 17 is detachably locked to the reinforcing locking frame 16.

[0032] In summary, the technical solution provided in this application also has the following advantages:

[0033] 1) This application adopts a curved support surface design to avoid deformation of components in the curved direction;

[0034] 2) Utilize multi-point support and clamping devices to reduce product shaking and collision;

[0035] 3) The U-shaped, non-open bottom of the product uses multi-arc support, so that when the product is hoisted, it will be supported by the surface and will not be damaged if it flips over;

[0036] 4) The side design is approximately triangular, saving space.

[0037] 5) This bracket supports the lower door frame panel, which is beneficial for supporting and protecting the door frame during the installation, riveting, and painting processes of the door frame panel.

[0038] In summary, this application achieves protection for the storage and movement of aircraft parts with irregular shapes and unstable centers through the use of curved support surfaces.

[0039] The technical solution of this application will be further described below through specific embodiments:

[0040] The technical issues to be addressed in this technical inspection are as follows.

[0041] 1) Prevent components from deforming in the curved direction;

[0042] 2) Saves space for product storage;

[0043] 3) Reduce product shaking and collisions during storage and movement;

[0044] 4) When packaging and shipping products, lift the products to prevent them from being overturned and damaged due to gravity.

[0045] The complete technical solution provided in this application is as follows:

[0046] Using a frame and a set of six curved pallets of different sizes, this multi-functional device, which integrates storage, riveting, and transportation of door frame panels, is parked in a suitable location. After the legs are adjusted to be balanced and stable, the parts or components that have been assembled off the shelf are lifted onto this device, with the curved surfaces fitting the pallets. When storing, pay attention to adjusting the lateral position of the product, placing it between the two long pallets on the left and right ends. The bottom of the curved surface of the component should fit against the four support devices, and two clamps should be used to clamp it, thus realizing the product storage function. The gaps in the frame can be used for riveting the inner and outer curved surfaces of the product. Transportation is achieved by pulling the tow bar.

[0047] Example 1

[0048] Design features, uses, and effects of each component:

[0049] 1) Frame: Used for overall support of this device and support after the product is placed inside. The hollow frame design allows for the operation space for riveting.

[0050] 2) Pallet: The curvature is designed according to the curvature of different support positions on the outer arc surface of the component. It is used to support the arc surface of the product. The support surface is fixed with felt. When packaging and shipping, the product is lifted through the product lifting tool hole. Due to gravity, the lower part of the product will rotate to a certain extent around the lifting tool hole. At this time, the arc surface of the pallet also plays a supporting role, which greatly reduces the product rotation angle. In the event of a slight collision, the felt on the support surface of the pallet plays a shock absorption and buffering role to avoid product damage.

[0051] 3) Traction device: The rubber plates at both ends fix the positions of the two ends of the product to prevent the product from moving. The traction rod can rotate around the axis point. Different traction angles are convenient for operators of different heights when traction is needed. When traction is not needed, the traction rod can be vertically fixed by the clips fixed to the rubber plates.

[0052] 4) Support rod: The support rod is controlled by a crank and screw thread to extend and retract. When moving, it retracts and lifts off the ground; when not moving, it extends to provide support.

[0053] 5) Clamping device: The opening and closing of the clamping head is controlled by a pin. When closed, the rubber clamping head is controlled by rotating the thread to compact the product.

[0054] 6) Support device: The four support devices in the middle of the bottom control the position of the bottom of the product's curved surface to prevent the product from sliding down.
