Technical Field

[0001] The invention relates to a mobile fork-loadable container transport device, belonging to the technical field of aviation container transport. Background Art

[0002] Air cargo container transportation is the future development trend of air transportation. Air cargo container equipment has been widely used abroad and has shown great advantages in loading and unloading efficiency and logistics management. In China, with the advent of my country's independent large-scale transport aircraft, efficient, fast and large-volume air transportation capabilities have been initially acquired, and the corresponding air cargo container equipment is also being developed. Among them, air cargo container pallets are one of the air cargo container equipment that has been developed and applied, and are being used more and more widely. In the future, the number of pallets owned by an airport will increase.

[0003] However, the air transport container pallets in the prior art cannot be forked and cannot be moved autonomously.

The fork frame and the fork support are both hollow tubular structures, which are both components of the fork assembly and part of the pallet structure. Its specific cross-sectional structural dimensions need to be specifically designed based on subsequent design calculations and force analysis to ensure the overall load-bearing capacity of the pallet; it is preferred that the fork assembly is fixedly connected with a fork reinforcement structure to improve its structural strength. The fork assembly and the fork reinforcement structure are made of aluminum alloy.

[0046] The frame 1 is designed as a rectangular frame according to the shape of the pallet structure. It is welded and fixed by two long frames and a short frame, and reinforced corner pieces are installed at the four corners of the frame; each frame 1 is provided with two forklift holes 5 for connecting with the forkway assembly 3 to realize forklift lifting operation. A serrated limiting structure 6 is fixedly connected to the frame 1, which can be docked and matched with the cargo system of the cargo hold floor of a large transport aircraft.

A plate-like structure as a mooring ring reinforcement structure 9 is fixedly connected to the corresponding part of the mooring ring mounting hole to ensure the installation strength of the mooring ring 7. The frame 1, the limiting structure 6 and the mooring ring reinforcement structure 9 are made of aluminum alloy.

[0047] There are two panels 2, an upper panel and a lower panel. Panel 2 is cut and processed from a complete aluminum alloy plate, and has good corrosion resistance and wear resistance after surface oxidation treatment.

[0048] The fork assembly 3 is formed into a whole by the fork frame and the fork support, which can ensure the structural strength of the fork as a whole. The fork frame and the fork support are both hollow tubular structures, which are both components of the fork assembly 3 and part of the pallet structure. The fork assembly 3 is fixedly connected with a long strip plate-shaped fork reinforcement structure 4 to improve its structural strength. The fork assembly 3 and the fork reinforcement structure 4 are made of aluminum alloy.

[0049] The core material is made of high-strength structural foam, with adjustable density, high compressive strength, shear strength, flame retardant properties, low water infiltration rate and not easy to mildew. The core material is used to fill the gap between the frame 1, the panel 2 and the fork assembly 3. Several pieces are provided according to the shape and size of the gap to increase the bearing capacity of the pallet structure.

[0050] The frame 1 is welded to the port of the forklift assembly 3 through the forklift hole 5 to form a whole. The panel 2 and the core material are bonded with glue. The panel 2 and the frame 1 are connected as a whole by a combination of glue bonding and rivet connection. The rivet connection uses countersunk rivets. The upper and lower surfaces are both complete planes with no protrusions on the surface.

[0051] The mooring ring 7 is fixedly connected to the limiting structure 6 through the mooring ring mounting threaded plate 8, the mooring ring reinforcement structure 9 and the fixing screws. The position of the limiting structure 6 where the mooring ring 7 is fixed is provided with a step-shaped structure to reduce the shear stress of the fixing screws.

[0052] Example 2

[0053] A mobile fork-loadable container transport equipment as described in Example 1, wherein the equipment also includes a caster module, the caster module is arranged at the bottom of the pallet structure, and the transport equipment is installed with 4 caster modules; the caster module can realize the rapid and flexible transportation of the transport equipment without changing the standard pallet limit size structure.

[0054] The caster module includes a caster 10 and a mounting assembly, and the caster 10 is detachably connected to the limiting structure 6 in the tray structure through the mounting assembly. The mounting assembly includes a caster mounting structure body, a mounting cover, a connecting plate 12 and a connecting shaft 11.

The installation components are all made of high-strength alloy steel with good load-bearing performance.

[0056] When the terminal cannot provide transfer tools such as cranes and forklifts, the traditional 463L aviation container pallet cannot be unloaded from the cargo hold, which causes the aviation container transportation system to be paralyzed and unable to work normally. The transportation equipment described in this embodiment can get rid of the dependence on transfer tools. When transfer tools such as cranes and forklifts cannot be provided, the transportation equipment can be lifted by using a cargo hold hoist, and the caster module can be installed to move it out of the cargo hold to the ground. In addition, the caster module can be applied to transport aircraft without slide rails in the cargo hold. By installing the caster module, the transportation equipment can be moved to a designated position in the cargo hold and tied up, which has a wider range of applicable scenarios.
