Description

Technical Field

[0001] The utility model relates to the technical field of aircraft tires, in particular to a disassembly device for an aircraft wheel hub. Background Technique

[0002] At present, aircraft tires adopt a tubeless and dual-tread structure, that is to say, they are not solid tires. The wheel has no inner tube, which is mainly convenient for disassembly, installation and maintenance. Air can be directly filled into the tire before flight. The high-strength sealing ring of the tire can ensure that the gas with a pressure value of up to several atmospheric pressures inside the tire does not leak, and its performance is incomparable with that of ordinary automobile tires, so its cost is quite high.

[0003] Half of the world's rubber consumption is used for tire production. It can be seen that tires are consumed very quickly. The speed of the aircraft and the impact during landing will cause severe wear of the tires. When the aircraft lands, the impact is very large. If the tires are still used after a certain amount of wear, it will cause potential risks. The currently commonly used aircraft tire demounting device, during the demounting process, first separates the tire from the wheel hub, then uses manual labor to remove the bolts on the wheel hub, and finally, collects the bolts, thereby realizing the demounting of the overall tire. However, since manual disassembly is time-consuming and laborious, and the removed bolts are easily lost, it affects the progress of the work. Content of the Utility Model

[0004] The purpose of the utility model is to provide a disassembly device for an aircraft wheel hub to solve the problems raised in the above background technique.

[0023] SeeFigures 1 to 3 A disassembly device for an aircraft wheel hub, comprising a base 1, a bracket 2, a fixing mechanism, and a disassembly mechanism. The fixing mechanism is arranged on the base 1 and is used for fixing the aircraft tire. A bracket 2 is arranged on one side of the base 1. A slide rail 3 is arranged at the top of the bracket 2. A linear motor 4 is slidably arranged on the slide rail 3. A first electric telescopic rod 5 and a support rod 6 are arranged on the linear motor 4. The output end of the first electric telescopic rod 5 is movably connected to the disassembly mechanism through a rotating shaft 7. The disassembly mechanism includes an operation disc 8, a rotating motor 9, and an operation gun 10. A plurality of rotating motors 9 are evenly arranged on the operation disc 8. The output end of the rotating motor 9 is provided with an operation gun 10. A groove 12 adapted to the wheel hub nut 11 is arranged at the top end of the operation gun 10. A chute 13 is arranged on the support rod 6. A slider 14 is slidably connected to the chute 13. A second electric telescopic rod 15 is arranged on the slider 14. One end of the second electric telescopic rod 15 is obliquely and fixedly connected to the operation disc 8. The linear motor 4, the rotating motor 9, the first electric telescopic rod 5, and the second electric telescopic rod 15 are all connected to the controller in a signal manner.

[0024] In this embodiment, for a disassembly device for an aircraft wheel hub provided by the present utility model, its working principle is as follows. First, the aircraft tire is fixed on the base 1 through the fixing mechanism, so that the side of the aircraft wheel hub with nuts faces the bracket 2. Subsequently, the controller starts the first electric telescopic rod 5 to drive the disassembly mechanism to move downward, and the slider 14 also moves downward accordingly. When it moves to the set position, the downward movement stops. At this time, the controller starts the second electric telescopic rod 15 to extend and move, so that the operation disc 8 rotates to the vertical direction through the rotating shaft 7. At this time, the operation gun 10 faces the nut on the aircraft wheel hub. Then, the linear motor 4 moves on the slide rail 3 at the top of the bracket 2 to move the groove 12 of the operation gun 10 to align with the nut on the aircraft wheel hub, and the movement stops. At this time, the controller starts a plurality of rotating motors 9 to rotate, driving the operation gun 10 to rotate, and at the same time disassembling a plurality of nuts on the aircraft wheel hub, thereby completing the rapid disassembly of the aircraft wheel hub from the aircraft tire, thus solving the problem that manual disassembly is time-consuming and laborious.

[0025] Specifically, the fixing mechanism includes fixing frames 16 arranged on both sides of the base 1 and a fixing groove 17 arranged in the middle of the bottom. A third electric telescopic rod 18 is arranged on the fixing frame 16. The output end of the third electric telescopic rod 18 is connected to an arc-shaped frame 19 adapted to the shape of the aircraft tire.

[0026] Exemplarily, the aircraft tire is fixed by the fixing frames 16 on both sides of the base 1. The third electric telescopic rod 18 drives the arc-shaped frame 19 adapted to the shape of the aircraft tire to move towards the aircraft tire until the arc-shaped frame 19 is in close contact with the outer surface of the aircraft tire.

[0027] Further, the fixing mechanism further includes a pressure plate 20 disposed at the front end of the top of the bracket 2, and the pressure plate 20 is connected to the bracket 2 through a fourth electric telescopic rod 21.

[0028] Exemplarily, the aircraft tire is further fixed by the pressure plate 20 at the front end of the top of the bracket 2 to make the fixation more firm, and it is not easy to shake when disassembling the nuts on the aircraft hub. Specifically, the fourth electric telescopic rod 21 drives the pressure plate 20 to move downward until the pressure plate 20 is in close contact with the outer surface of the aircraft tire.

[0029] Specifically, a magnetic attraction element (not shown in the figure) is provided in the groove 12, and the magnetic attraction element is connected to the controller by signal.

[0030] Specifically, a storage groove 22 is further provided on the base 1, and the storage groove 22 is located directly below the operation panel 8.

[0031] Exemplarily, the disassembled nuts can be stored by the magnetic attraction element. The controller controls the magnetic attraction element to generate magnetism, and the disassembled nuts are attracted by the magnetic attraction element. At this time, the second electric telescopic rod 15 retracts inward, so that the operation panel 8 returns to the horizontal position, exactly aligning with the storage groove 22 on the base 1. The controller controls the magnetic attraction element to lose magnetism. At this time, the disassembled nuts just all fall into the storage groove 22, thereby realizing the storage of the disassembled nuts and avoiding the loss of the disassembled nuts.

[0032] Specifically, the storage groove 22 is in the shape of a circular groove.

[0033] Exemplarily, the storage groove 22 is in the shape of a circular groove to adapt to the shape of the operation panel 8, so that the fallen nuts can all fall into the storage groove 22.

[0034] It should be noted that the controller, the linear motor 4, the electric telescopic rod, and the rotary motor 9 used in the above embodiments are all conventional electronic components for those skilled in the art. The specific connection circuit and how to select the specific model are common knowledge for those skilled in the art, and the above embodiments will not be specifically described.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of protection of the present invention.
