Description

Technical Field

[0001] The utility model belongs to the technical field of comprehensive aviation technology support and relates to a portable aircraft wheel disassembly and assembly device. Background Art

[0002] Aircraft frequently conduct missions, often encountering poorly maintained airport runways. This can easily lead to wheel failures or tire wear, necessitating wheel removal for inspection or tire replacement. Traditionally, this involved lifting the wheel assembly, removing the retaining bolts, and manually removing the wheel. This weighs approximately 50 kg, making removal labor-intensive and time-consuming. Furthermore, existing wheel removal equipment comes in a variety of sizes and is bulky, taking up space during transportation and storage, making it inadequate for rapid aircraft deployment. Utility Model Content

[0003] The purpose of the utility model is to provide a portable aircraft wheel disassembly and assembly device, which has the characteristics of being easy to carry, convenient to use and highly versatile.

[0004] Technical Solution: A portable aircraft wheel removal and assembly device comprises a chassis, a power unit, a lifting device, and a bracket. The power unit is fixed to the chassis, the bracket is detachably connected to the lifting device, and the lifting device is connected to the power unit. The power unit drives the lifting device to raise and lower to adjust the height of the bracket from the ground. The chassis is also equipped with two arms, and the bracket is located inside the two arms.

[0005] In the aforementioned portable aircraft wheel disassembly and assembly device, both arms are hinged to the main structure of the base frame via a hinge mechanism.

[0006] In the aforementioned portable aircraft wheel disassembly and assembly equipment, tire fixing buckles are also provided at the four corners of the chassis.

[0007] In the aforementioned portable aircraft wheel disassembly and assembly equipment, the bracket and the lifting device are detachably connected via quick-release bolts.

[0008] In the aforementioned portable aircraft wheel removal and assembly device, two elastic straps are fixed diagonally to the tire fixing buckle.

[0009] In the aforementioned portable aircraft wheel disassembly and assembly equipment, the lifting device is slidably connected to the base frame via vertical guide rails.

[0010] Beneficial effects

[0011] The utility model can not only adapt to tires of various sizes and has high versatility, but also can be folded through a hinge structure, thereby reducing the overall size and being easy to carry outside. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a top view of the utility model. DETAILED DESCRIPTION

[0013] The portable aircraft wheel disassembly and assembly device of the utility model is described in detail with reference to the accompanying drawings:

[0014] Example 1. A portable aircraft wheel disassembly and assembly device, comprising: Figure 1 As shown, mainly by Figure 1 The structure shown in the figure is assembled and mainly includes a base frame 1, a power unit 2, a lifting device 3, a bracket 4, a hinge mechanism 5, a tire fixing ring 6, a support arm 7, and a vertical guide rail 8. The power unit 2 is fixed to the base frame 1, the bracket 4 is detachably connected to the lifting device 3, and the lifting device 3 is connected to the power unit 2; the power unit 2 drives the lifting device 3 to rise and fall to adjust the height of the bracket 4 above the ground. The base frame 1 is also equipped with two support arms 7, and the bracket 4 is located inside the two arms 7.

[0015] Both arms 7 are hinged to the main structure of the base frame 1 via a hinge mechanism 5 .

[0016] Tire fixing ring buckles 6 are also provided at the four corners of the chassis 1 .

[0017] The bracket 4 and the lifting device 3 are detachably connected via quick-release bolts.

[0018] The tire fixing buckle 6 is fixed with two elastic straps along the diagonal direction.

[0019] The lifting device 3 is slidably connected to the base frame 1 via a vertical guide rail 8, and the vertical guide rail 8 and the base frame 1 are reinforced by reinforcing ribs.

[0020] The chassis 1 is also provided with casters for easy transportation.

[0021] During use, the device is inserted sideways into the lower portion of the wheel. The power unit 2 drives the lifting device 3 upward, and the bracket 4 rises accordingly to support the wheel. At this point, the wheel is removed from the aircraft and secured with two fixed elastic straps, which are interlaced and connected to the tire retaining ring 6 to prevent accidental detachment during transportation. After removal, the portable aircraft wheel removal and assembly device can be used to remove the wheel for maintenance. When the wheel removal and assembly device is finished, the quick-release bolts can be removed to remove the bracket 4, and the hinge device 5 can be used to fold the base frame 1 inward to reduce the overall size for easy storage and transportation. Tires of different sizes can be removed by replacing the brackets 4.

[0022] In summary, the utility model is not only adaptable to tires of various sizes and has high versatility, but also can be folded through a hinge structure, thereby reducing the overall size and being easy to carry outside.
