Description

Technical Field

[0001] The utility model relates to the technical field of aircraft maintenance, in particular to a maintenance and detection device for aircraft wheels. Background Art

[0002] Aircraft wheels are important components of an aircraft, directly affecting operations such as taxiing, takeoff, and landing on the ground. Their design and functions are aimed at ensuring the safety, stability, and operational performance of the aircraft under various ground conditions. Aircraft wheels generally adopt a split structure, and two rims and tires are symmetrically connected on both sides of the wheel assembly to enhance the stability of the aircraft wheels. During the taxiing, takeoff, and landing of the aircraft, the aircraft wheels will bear huge pressure and impact, and it is necessary to frequently detect, repair, and replace the wheel assembly, rim, or tire. In traditional technology, when detecting, repairing, disassembling, and replacing aircraft wheels, a jack needs to be inserted under the wheel assembly between the two rims, and the aircraft wheel is jacked up for maintenance and disassembly operations. However, the number of related instruments and tools is large, the weight is heavy, and they are inconvenient to move and use, which will increase the workload of operators. Therefore, the technical field of aircraft maintenance needs to propose a technical solution to improve the convenience and labor-saving degree of the aircraft wheel maintenance and detection device.

[0026] Embodiment 1

[0027] Referring to the attached Figures 1-4 , the present application provides a maintenance and inspection device for aircraft wheels, including a support plate 1, a support wheel 2 and a jack mechanism 3. The support wheel 2 is arranged below the support plate 1. A storage slot 4 is arranged above the support plate 1. A first opening 5 is arranged on one side of the support plate 1. A first slide rail 6 is arranged on the side wall of the first opening 5. The jack mechanism 3 includes a connecting plate 7, a jack body 8 and a jack support wheel 9. A first slider 10 matched with the first slide rail 6 is arranged on the side wall of the connecting plate 7. The connecting plate 7 is detachably arranged in the first opening 5 through the first slider 10 and the first slide rail 6. The jack support wheel 9 is connected to the connecting plate 7 through a support wheel rotating shaft 11. The jack support wheel 9 can rotate around the support wheel rotating shaft 11 to the side or above of the connecting plate 7. When the jack support wheel 9 is arranged in different positions of the connecting plate 7, it can be fixed by the friction force between the support wheel rotating shaft 11 and the connecting plate 7 to avoid moving. The jack body 8 is arranged in the middle above the connecting plate 7. By arranging the storage slot 4, the maintenance and inspection tools can be placed in the storage slot 4, and are transported by the support plate 1 and the support wheel 2 below the support plate 1. At the same time, a first opening 5 is arranged on the front side of the support plate 1, which can be slidably connected to the jack mechanism 3. Referring to the attached Figure 2 With the attached Figure 3 , when the jack mechanism 3 needs to be used, it is pushed out by using the jack support wheel 9, so that the jack mechanism 3 is completely separated from the support plate 1. After further pushing the jack mechanism 3 under the wheel assembly between the two rims and the tire, the jack support wheel 9 is rotated so that the jack support wheel 9 rotates to the top or side of the connecting plate 7, and the connecting plate 7 and the jack body 8 are placed flat, so that the jack body 8 can work normally. To sum up, by arranging the cooperation of the storage slot 4 and the first opening 5, the jack mechanism 3 and other maintenance and inspection tools can move together with the support plate 1, which can improve the convenience and labor-saving degree of aircraft wheel maintenance and inspection.

[0028] Specifically, a wheel transport plate 12 is provided on one side of the support plate 1. By providing the wheel transport plate 12 in this device, the wheels for replacement and the removed wheels can be placed above the wheel transport plate 12, making the operation of this device more labor-saving and convenient.

[0029] Specifically, an inverted trapezoidal card slot 13 is provided above the wheel transport plate 12. By providing the inverted trapezoidal card slot 13 above the wheel transport plate 12 in this device, the wheels for replacement and the removed wheels can be placed more stably above the wheel transport plate 12.

[0030] Specifically, a folding stop bar 14 and a stop bar placement groove 15 are symmetrically provided on both sides of the inverted trapezoidal card slot 13. The folding stop bar 14 includes a first stop bar 16 and a second stop bar 17. One side of the first stop bar 16 is hinged to one side of the stop bar placement groove 15, and the other side of the first stop bar 16 is hinged to the second stop bar 17. Refer to the attached Figure 4 , by providing the folding stop bar 14 in this device, when transporting, the first stop bar 16 and the second stop bar 17 are unfolded to block the inverted trapezoidal card slot 13 and prevent the wheels from slipping out. At the same time, when the wheels are taken out or placed, the first stop bar 16 and the second stop bar 17 can be folded and placed into the stop bar placement groove 15 to prevent the folding stop bar 14 from affecting the taking out and placing of the wheels, improving the convenience and reliability of this device.

[0031] Specifically, a cylindrical card slot 18 is provided on the side of the stop bar placement groove 15 that is not connected to the first stop bar 16. By providing the cylindrical card slot 18 in this device, when the folding stop bar 14 is unfolded, one side of the second stop bar 17 can be inserted into the cylindrical card slot 18, making the unfolding of the folding stop bar 14 and the fixation of the wheels more stable.

[0032] Embodiment 2

[0033] Refer to the attached Figures 1-5, the difference between this embodiment and Embodiment 1 is that two second openings 19 are symmetrically arranged on both sides of the first opening 5, a second slide rail 20 is arranged on the side wall of the second opening 19, there are two wheel transport plates 12, and a second slider 21 that cooperates with the second slide rail 20 is arranged on the side wall of the wheel transport plate 12. The two wheel transport plates 12 are slidably arranged in the second opening 19 through the second slide rail 20 and the second slider 21. And the support wheels 2 are also arranged below the wheel transport plate 12. By arranging the second opening 19, the wheel transport plate 12 can slide at the second opening 19. After the aircraft wheels are lifted by the jack mechanism 3, the wheel transport plate 12 can be pushed under the wheels, making the disassembly, transportation and installation of the wheels more convenient.

[0034] Specifically, first limit blocks 22 are arranged on both sides of the second opening 19, and a second limit block 23 is arranged on one side of the wheel transport plate 12. The cooperation between the first limit block 22 and the limit plate can prevent the wheel transport plate 12 from completely sliding out and falling, improving the reliability of the device.

[0035] Specifically, a first push handle 24 is arranged above the connecting plate 7 and above the wheel transport plate 12. By arranging the first push handle 24, the jack mechanism 3 and the wheel transport plate 12 can be slid out more conveniently.

[0036] Specifically, a second push handle 25 is arranged above one side of the support plate 1. By arranging the second push handle 25, the operator can conveniently push the device to move through the second push handle 25, making the movement of the device more labor-saving.

[0037] Specifically, support disks 26 and support rotating shafts 27 are symmetrically arranged at the bottom of the connecting plate 7. Refer to the attached Figure 3 and the attached Figure 5 , when the jack support wheel 9 rotates above or to the side of the connecting plate 7, after the connecting plate 7 and the jack body 8 are laid flat, the support disk 26 is turned out around the support rotating shaft 27 to support the bottom of the connecting plate 7, avoiding the shaking of the connecting plate 7 and the jack body 8 during the operation of the jack 8, and effectively reducing the potential safety hazards during the maintenance and inspection process.
