[0028] Example:

[0029] like Figures 1 to 4 The figure shows a storage and transport vehicle for the main landing gear inner tube of an Airbus aircraft A330 according to this embodiment, which includes a vehicle chassis 14 , a front lower support frame 1 , a front upper support frame 3 and a rear lower support frame 5 .

[0030] The underframe 14 of this embodiment is welded from square tubes having a size of 80*80 mm. Casters are provided below the underframe 14, including two 6-inch silent universal wheels 7 at the front end of the underframe 14 and two 6-inch silent fixed wheels 6 at the rear end of the underframe 14.

[0031] The front lower support frame 1 and the rear lower support frame 5 are respectively mounted at the front and rear of the underframe 14 and are located on the same horizontal plane. The distance between the front lower support frame 1 and the rear lower support frame 5 is referenced to the center point of the main landing gear inner tube and must be sufficient to ensure the balance and stability of the main landing gear inner tube during storage. Concave lower support grooves 8 are formed at the upper ends of the front and rear lower support frames, respectively. The lower portion of the main landing gear inner tube's main body 12 is supported in these grooves during transport and storage. The front upper support frame 3 snaps onto the top of the front lower support frame 1. During use, the front end of the main landing gear inner tube is clamped between the front lower support frame 1 and the front upper support frame 3.

[0032] The specific structure of the front upper support frame 3 being fastened to the front lower support frame is as follows: one end of the front upper support frame 3 is hingedly connected to one end of the front lower support frame 1 via a hinge 4, allowing the front upper support frame 3 to be flipped up and down relative to the front lower support frame 1. The other end of the front upper support frame 3 is connected to the other end of the front lower support frame 1 via a quick-release screw 2. When in use, the front upper support frame 3 can be released by disassembling or tightening the quick-release screw 2.

[0033] The specific installation structure of the quick-release screw 2 is as follows: Figure 2 As shown, the connecting ends of the front upper support frame 3 and the front lower support frame 1 are provided with notches 15 that pass through from top to bottom. The lower end of the quick-release screw 2 is rotatably connected to the notch 15 of the front lower support frame 1. When locking is required, the quick-release screw 2 is inserted into the notch 15 of the front upper support frame 3, and the nut at the upper end of the quick-release screw 2 is tightened to lock it.

[0034] In this embodiment, a 3mm-thick PVC anti-wear material protective layer 9 is provided on the surfaces of the front lower support frame 1, rear lower support frame 5, and front upper support frame 3 that contact the main landing gear inner tube. The PVC anti-wear material protective layer 9 is secured with countersunk screws. The PVC anti-wear material protective layer 9 effectively protects the surface of the main landing gear inner tube from damage.

[0035] In this embodiment, the front lower support frame 1 and the rear lower support frame 5 are respectively provided with lower inclined rods 11 that are inclined outwards. The lower inclined rods 11 are located on both sides of the lower support groove 8, so that the lower support groove 8 forms an upwardly open shape. The front upper support frame 3 is also provided with upper inclined rods 10 that are inclined outwards on both sides, so that the front upper support frame 3 forms a downwardly open shape.

[0036] The total weight of the storage and transport vehicle of this embodiment is approximately 80 kg. This weight is determined based on the weight of the main landing gear inner cylinder and the convenience of transportation. If the storage and transport vehicle is too heavy, combined with the weight of the main landing gear inner cylinder, the labor intensity of the workers when operating the storage and transport vehicle to transport the main landing gear inner cylinder will increase, making it inconvenient to use; if it is too light, there is a risk of instability or even slipping when transporting the main landing gear inner cylinder and storing it.

[0037] When the storage and transport vehicle of this embodiment is in use, the quick-release screw 2 is loosened and the front upper support frame 3 is flipped upward to the side of the front lower support frame 1, and the main landing gear inner tube can be lifted onto the front lower support frame 1 and the rear lower support frame 5. The front lower support frame 1 and the rear lower support frame 5 will support the front and rear ends of the main body 12 of the main landing gear inner tube. Then, the front upper support frame 3 is flipped and closed, and the quick-release screw 2 is locked to complete the fixation of the main landing gear inner tube. After that, the main landing gear inner tube can be transported and stored.

[0038] When the main landing gear inner tube needs to be taken out, loosen the quick-release screw 2, flip the front upper support frame 3 upward to the side of the front lower support frame 1, and then the main landing gear inner tube can be taken out.

[0039] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention, and the implementation methods of the present invention are not limited thereto. All other modifications, replacements or changes made to the above structure of the present invention based on the above contents of the present invention, in accordance with common technical knowledge and customary means in this field, without departing from the above basic technical ideas of the present invention, should fall within the scope of protection of the present invention.
