Description

Technical Field

[0001] The utility model relates to the technical field of wheel tire installation, in particular to an aircraft wheel tire installation tool. Background Art

[0002] Aircraft wheels are key components of aircraft landing systems. They include structures such as the hub and must withstand the tremendous impact and friction during landing, as well as the weight of the aircraft during taxiing. When replacing tires, an aircraft wheel mounting tool is required. Due to the large size and weight of aircraft wheels and tires, manual installation is difficult to ensure precise positioning of the tire and wheel, and can easily lead to deviations. The mounting tool's support base secures the wheel, the carcass fixture stabilizes the tire, and the drive mechanism steadily pushes the tire onto the wheel hub, ensuring stability and accuracy during the installation process. This tool also improves installation efficiency, ensures personnel safety, and avoids poor installation quality and potential hazards caused by manual operation.

[0003] When using traditional aircraft wheel tire installation tooling, the wheel is first placed on the tooling's support base, and the base's positioning device is used to ensure the wheel's accurate position; then the tire is placed in the tire carcass fixture and clamped to stabilize the tire; then the drive mechanism is started, and the drive mechanism pushes the tire toward the wheel hub through the push plate connected to it. During this process, the auxiliary guide components play a role, ensuring that the tire is aligned with the wheel hub in the correct direction until the tire is completely installed on the wheel hub. The entire process must ensure that all parts of the tooling work together to achieve efficient, accurate and damage-free tire installation operations.

[0004] Traditional aircraft wheel tire installation tools typically place the tire carcass directly on a mobile vehicle when installing or removing it. This setup can easily cause the tire to roll or tip over within the work area, potentially harming operators and surrounding equipment. It also requires repeated adjustments, reducing transportation efficiency. Utility Model Content

[0009] Furthermore, the outer wall of the support seat is fixedly connected to a motor, the output end of the motor is fixedly connected to a rotating shaft, the outer wall of the rotating shaft is fixedly connected to a worm, the interior of the support seat is rotatably connected to a worm wheel, the worm gear is engaged with the worm wheel, and a lifting assembly is provided inside the worm wheel, the lifting assembly is used to drive the lifting seat to rise and fall, and the lower surface of the lifting seat is fixedly connected to a guide rod.

[0010] Furthermore, the lifting assembly includes a screw rod, the outer wall of the screw rod is threadedly connected to the inside of the worm wheel, the top of the screw rod is fixedly connected to a connecting seat, and the upper surface of the connecting seat is fixedly connected to the lower surface of the lifting seat.
