Description

Technical Field

[0001] This invention relates to the field of aircraft inspection technology, and in particular to an aircraft air intake inspection device. Background Technology

[0002] During flight, various foreign objects may enter the air intake of an aircraft, causing damage to its internal structure. Therefore, before and after flight, equipment maintenance personnel need to inspect all channels of the aircraft to ensure that there are no foreign objects or structural damage that could cause an accident.

[0003] Previously, when inspecting various passages of the aircraft, special equipment maintenance personnel had to crawl into the passages to conduct the inspection. The passages were small and had a smooth protective coating. Some special passages had protective structures that the equipment maintenance personnel could not pass through. They could only use auxiliary observation equipment (cameras, telescopes, flashlights, etc.) to observe through the protective structures. The viewing angle and light were limited, making the inspection time-consuming and laborious, and the results of visual observation were not very accurate. Summary of the Invention

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] The purpose of this invention is to provide an aircraft air intake inspection device that saves time and effort and can produce more accurate inspection results.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1-7 As shown, this embodiment provides an aircraft air intake inspection device 100, including a frame 1, a walking mechanism, a lifting and observing mechanism, a bracket, a toggle mechanism, a pathfinding camera component 15, and a lidar 16. The walking mechanism is mounted on the frame 1 and can drive the frame 1 to move. The lifting and observing mechanism includes a first rotary drive component, a turntable 2, a lifting drive assembly, a Y-axis rotation assembly, an X-axis rotation assembly, and an observing component 12. The first rotary drive component is disposed on the frame 1, and the turntable 2 is disposed on the upper part of the first rotary drive component. The first rotary drive component is used to drive the turntable 2 to rotate. In this embodiment, the turntable 2 is fixedly sleeved on the power output shaft of the first rotary drive component. The power output shaft of the rotary drive component is vertically arranged. The lifting drive component is set on the turntable 2. The Y-axis rotation component is set on the upper part of the lifting drive component. The lifting drive component is used to drive the Y-axis rotation component to lift and lower. The X-axis rotation component is set on the Y-axis rotation component. The Y-axis rotation component is used to drive the X-axis rotation component to rotate. The observation component 12 is set on the X-axis rotation component. The X-axis rotation component is used to drive the observation component 12 to rotate. The bracket is set at the front end of the frame 1. The road detection camera component 15 and the lidar 16 are both set at the front end of the bracket. The toggle mechanism includes a toggle drive component and a toggle element. The toggle drive component is set on the bracket. The toggle drive component is used to drive the toggle element to move.

[0031] The lifting and observation mechanism in this embodiment can rotate in multiple directions, thereby ensuring that the observation component 12 can take pictures from multiple angles, facilitating personnel to obtain internal information from the outside. When it is necessary to pass through the protective structure in the aircraft passage, the lifting drive component drives the Y-axis rotation component, X-axis rotation component, and observation component 12 to descend, reducing the space occupied and allowing it to pass through the narrow gaps in the protective structure, smoothly passing through obstacles that the human body cannot cross, and entering the equipment for inspection. After entering the equipment, the first rotation drive component, lifting drive component, Y-axis rotation component, and X-axis rotation component adjust the observation component 12 to the required angle. The lidar 16 at the front end of the bracket is used to measure the distance between the device and obstacles or inspection points in front, and the path-finding camera component 15 is used to observe the road conditions ahead and the movement of the toggle component; for blades in some special flight equipment, a special mechanism is locked on the blade protective cover. During operation, the toggle component just contacts the fan blade, and the toggle drive component drives the toggle component to move, thereby rotating the fan blade. Then, the observation component 12 is adjusted to a suitable angle to observe whether the fan blade is damaged. This device allows for various inspections of the internal structure without the need for maintenance personnel to enter the passageway, saving time and effort and providing more accurate inspection results.

[0032] The lifting drive assembly includes a second rotary drive component 3, a first lifting rod 4, a second lifting rod 5, and a support shaft.

The lower end of the first lifting rod 4 is fixedly sleeved on the power output shaft of the second rotary drive component 3, and the upper end of the first lifting rod 4 is hinged to the Y-axis rotation assembly. The power output shaft of the second rotary drive component 3 is horizontally arranged, that is, the power output shaft of the second rotary drive component 3 is perpendicular to the power output shaft of the first rotary drive component. In this embodiment, a vertical plate 6 is provided on the turntable 2, and the power output shaft of the second rotary drive component 3 is rotatably mounted in the vertical plate 6, that is, the power output shaft of the second rotary drive component 3 is supported by the vertical plate 6. A support shaft is provided on one side of the second rotary drive component 3. The support shaft is located away from the power output shaft of the second rotary drive component 3 and is parallel to the power output shaft of the second rotary drive component 3. The lower end of the second lifting rod 5 is rotatably sleeved on the support shaft, and the upper end of the second lifting rod 5 is hinged to the Y-axis rotating assembly. The first lifting rod 4 and the second lifting rod 5 are parallel to each other. In this embodiment, the first lifting rod 4, the second lifting rod 5, the second rotary drive component 3, and the Y-axis rotating assembly form a parallelogram structure. During operation, when the second rotary drive component 3 drives the first lifting rod 4 to rotate downward, the second lifting rod 5 will also rotate downward, enabling the Y-axis rotating assembly to descend. When the second rotary drive component 3 drives the first lifting rod 4 to rotate upward, the second lifting rod 5 will also rotate upward, enabling the Y-axis rotating assembly to rise.

A rotating shaft is provided at the end of the observation component 12 away from the first side plate 102. The rotating shaft is rotatably mounted on the second side plate 103, thereby enabling the observation component 12 to rotate stably under the drive of the X-axis rotation drive component 11. The power output shaft of the X-axis rotation drive component 11 is perpendicular to the power output shaft of the Y-axis rotation drive component, that is, the power output shaft of the X-axis rotation drive component 11 is horizontally arranged. The X-axis rotation drive component 11 can drive the observation component 12 to rotate around a horizontal axis.
