[0029] Example:

[0030] like Figures 1 to 4The figure shows a storage and transportation vehicle for the front landing gear outer cylinder of the Airbus A320 aircraft according to this embodiment, which comprises a vehicle bottom frame 1 , a vehicle handle 2 , a front fixing frame 3 and two rear fixing frames 4 .

[0031] The vehicle frame 1 is horizontally arranged and welded from 50*50 square tubes. The handlebar 2 is arranged at the rear of the vehicle frame 1, and the handlebar 2 extends and tilts upward and backward. A transverse round tube 201 is arranged above the handlebar 2, and the transverse round tube 201 can facilitate the staff to push and store the transport vehicle during transportation.

[0032] In this embodiment, fixed wheels 7 are respectively provided on both sides of the front end of the vehicle chassis 1, and the fixed wheels 7 are 5-inch silent wheels. Universal wheels 8 are respectively provided on both sides of the rear end of the vehicle chassis 1, and the universal wheels 8 are 5-inch universal silent wheels. The universal wheels 8 can facilitate the change of direction during the transportation of the vehicle.

[0033] The front fixing frame 3 is arranged at the front part of the vehicle bottom frame 1, and the front fixing frame 3 is used to fix the lower end of the cylinder 901 of the outer cylinder 9 of the front landing gear of the aircraft. The front fixing frame 3 includes a first U-shaped support frame 301, a first pressure rod 302 and a first quick release screw 303. Both sides of the first U-shaped support frame 301 are fixedly connected to the vehicle bottom frame 1 through connecting rods 6 extending downwards, and a PVC protective plate 5 with a thickness of 3 mm is arranged on the bottom supporting surface of the first U-shaped support frame 301, the inner side surface of the first U-shaped support frame 301, and the bottom of the first pressure rod 302. The PVC protective plate 5 can prevent the outer surface of the cylinder 901 of the outer cylinder 9 of the front landing gear of the aircraft from being scratched.

[0034] Among them, the first pressure rod 302 is detachably connected to the upper end of the first U-shaped support frame 301 through the first quick-release screw 303. During transportation and storage, the lower end of the cylinder body 901 of the aircraft's front landing gear outer tube 9 will be stuck in the first U-shaped support frame 301, and the first pressure rod 302 will be tightly pressed on the upper part of the lower end of the cylinder body 901, thereby restricting the lower end of the cylinder body 901 of the aircraft's front landing gear outer tube 9 between the first U-shaped support frame 301 and the first pressure rod 302.

[0035] like Figure 2As shown, the upper end of the first quick-release screw 303 of this embodiment is threadedly connected with the first plum blossom-shaped handle 304, and the two ends of the first pressure rod 302 are respectively connected through the first quick-release screw 303. The specific connection structure is: a notch 307 is provided at the end of the first pressure rod 302, and a mounting groove 306 is provided at the upper end of the first U-shaped support frame 301. The lower end of the first quick-release screw 303 is rotatably connected to the mounting groove 306 through a pin 305. When the first pressure rod 302 is fixed, the first quick-release screw 303 is rotated upward so that the first quick-release screw 303 is stuck in the notch 307. At this time, the first plum blossom-shaped handle 304 is located above the first pressure rod 302. The first plum blossom-shaped handle 304 is rotated so that it is pressed against the first pressure rod 302, and the locking is completed.

[0036] Two rear fixing frames 4 are arranged on the left and right sides of the rear part of the vehicle bottom frame 1, and the two rear fixing frames 4 are used to fix the side frames 902 on both sides of the upper end of the outer tube 9 of the front landing gear of the aircraft. The rear fixing frame 4 includes a second U-shaped support frame 404, a second pressure rod 403 and a second quick release screw 401. The lower side of the second U-shaped support frame 404 is fixedly connected to the vehicle bottom frame 1 through a connecting rod 6. A PVC protective plate 5 with a thickness of 3 mm is arranged on the bottom support surface of the second U-shaped support frame 404, the inner side surface of the second U-shaped support frame 404 and the lower side of the second pressure rod 403 to avoid scratching the outer surface of the outer tube 9 of the front landing gear of the aircraft.

[0037] The PVC protective plates 5 on the first U-shaped support frame 301 and the second U-shaped support frame 404 are both fixed by countersunk screws.

[0038] The second pressure rod 403 is detachably connected to the upper end of the second U-shaped support frame 404 through the second quick-release screw 401. During transportation and storage, the oblique rods 904 of the side frames 902 on both sides of the upper end of the outer tube 9 of the front landing gear of the aircraft will be stuck in the second U-shaped support frame 404, and the second pressure rod 403 will be pressed on the oblique rods 904 of the side frames 902, so that the oblique rods 904 of the side frames 902 on both sides of the upper end of the outer tube 9 of the front landing gear of the aircraft are restricted between the second U-shaped support frame 404 and the second pressure rod 403. The upper end of the second quick-release screw 401 of this embodiment is fixedly provided with a second plum blossom-shaped handle 402, and the two ends of the second pressure rod 403 are fixedly connected by the second quick-release screw 401 respectively.

[0039] Among them, the bottom supporting surface of the first U-shaped support frame 301 and the bottom supporting surfaces of the two second U-shaped support frames 404 are on the same horizontal plane, which can ensure that there is no gap after the front fixing frame 3 and the two rear fixing frames 4 lock the front landing gear outer tube 9 of the Airbus A320 aircraft, and there will be no shaking during transportation.

[0040] The total weight of the storage and transport vehicle of the present embodiment is approximately 20 kg, which is a conclusion drawn in combination with the weight of the outer cylinder of the front landing gear of the aircraft and the convenience of transportation. If the storage and transport vehicle is too heavy, combined with the weight of the outer cylinder of the front landing gear of the aircraft, it will cause the workers to operate the storage and transport vehicle with high labor intensity during transportation, and it will be inconvenient to use; if it is too light, it will cause the outer cylinder of the front landing gear of the aircraft to be unstable during transportation.

[0041] like Figure 5 As shown ( Figure 5 The storage and transport vehicle and the outer tube of the aircraft's front landing gear are further simplified schematic diagrams, so they are similar to Figures 1 to 4 The schematic diagrams shown are different, but the technical solutions expressed are the same). When the front landing gear outer cylinder 9 of the Airbus A320 aircraft is locked on the storage and transportation vehicle, the front landing gear outer cylinder 9 of the aircraft will be in a horizontal state, the lower end of the cylinder body 901 of the front landing gear outer cylinder 9 of the aircraft will be tightly locked by the front fixing frame 3, and the inclined rods 904 of the side frames 902 on both sides of the upper end of the front landing gear outer cylinder 9 of the aircraft will be tightly locked by the two rear fixing frames 4, thereby forming three fixing points for the front landing gear outer cylinder 9 of the aircraft, so that the front landing gear outer cylinder 9 of the aircraft is very stable during transportation and storage. When the front landing gear outer cylinder 9 of the Airbus A320 aircraft needs to be unloaded from the storage and transportation vehicle, it is only necessary to loosen one of the first quick-release screws 303 of the front fixing frame 3 and one of the second quick-release screws 401 of each of the two rear fixing frames 4, that is, loosen the three quick-release screws. The first quick-release screw 303 and the second quick-release screw 401 can be quickly locked and unlocked during the process of storing or lifting the front landing gear outer cylinder 8 of the Airbus A320 aircraft.

[0042] The above-mentioned embodiments of the utility model are not intended to limit the protection scope of the utility model, and the implementation methods of the utility model are not limited to these.
