Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example 1:
[0026] Please see Figures 1 to 2 This embodiment provides a ground-based test device for detecting external damage to an aircraft engine, including a base box 1, with an all-around detection assembly mounted on the top of the base box 1.
[0027] The all-around inspection assembly includes a stand 2 and a frustum 3 fixedly connected to the top of the base box 1. A cylinder 4 is fixedly connected to the top of the stand 2. An inspection cover 5 is fixedly connected to the output shaft of the cylinder 4. An infrared scanning device 6 is fixedly connected to the inner side of the inspection cover 5. A positioning plate 7 is fixedly connected to the top of the frustum 3. A rotating shaft 8 is rotatably connected to the inner bottom wall of the frustum 3. A turntable 9 is fixedly connected to the top of the rotating shaft 8. A rotating groove 10 is opened on the top of the positioning plate 7. A motor 11 is fixedly connected to the inside of the frustum 3. A first gear 12 is fixedly connected to the output shaft of the motor 11. A second gear 13 is fixedly connected to the outer surface of the rotating shaft 8. In use, the operator first needs to hoist the aircraft engine to the top of the turntable 9. Then, the cylinder 4 is started, which drives the inspection cover 5 to move vertically downward, so that the aircraft engine is covered inside the inspection cover 5.
[0028] Once the aircraft engine is completely covered by the inspection cover 5, the motor 11 is started. Through the meshing transmission of the first gear 12 and the second gear 13, the rotating shaft 8 is driven to rotate in the opposite direction to the output shaft of the motor 11, thereby causing the aircraft engine to rotate continuously on the top of the turntable 9. At this time, the infrared scanning device 6 is turned on, which can automatically scan multiple surfaces and parts of the aircraft engine to inspect its exterior and confirm whether there is any damage.
[0029] It should be noted that the outer diameter of the turntable 9 is smaller than the inner diameter of the rotating groove 10, and the top of the rotating shaft 8 passes through the positioning plate 7 and extends to the inner side of the rotating groove 10.
[0030] It should be understood that the first gear 12 and the second gear 13 mesh and drive each other, and the outer diameter of the detection cover 5 and the turntable 9 are the same.
[0031] The inner side of the support frame 2 is fixedly connected to a sliding rod 14, and the left and right sides of the detection cover 5 are fixedly connected to moving blocks 15. The moving blocks 15 are slidably connected to the sliding rod 14. By setting the moving blocks 15 and the sliding rod 14, the sliding limit detection cover 5 is achieved.
[0032] Meanwhile, a magnetic platform 16 for adsorption and fixation is fixedly connected to the top of the turntable 9.
[0033] In addition, a fan 17 is fixedly connected to the right side of the bottom box 1, and a collecting sponge 18 is glued to the inside of the bottom box 1. By setting up the fan 17 and the collecting sponge 18, after the aircraft engine is inspected, it can be placed inside the bottom box 1. The fan 17 blows away the oily debris on its outer surface and in the gaps, and the collecting sponge 18 collects and adheres to it for easy cleaning.
[0034] Example 2:
[0035] Please see Figures 3 to 4 Based on Embodiment 1, the bottom box 1 is hinged to the front of a movable door 19 for sealing, and a door handle is fixedly connected to the outer surface of the movable door 19. The bottom box 1, the upright frame 2 and the truncated cone 3 are all steel structures.
[0036] The truncated cone 3 has heat dissipation vents 20 on both the front and back sides. A filter grille 21 is fixedly connected to the inner side of the heat dissipation vent 20. The filter grille 21 is made of wire mesh. By setting the heat dissipation vent 20 and the filter grille 21, the effects of ventilation and heat dissipation and dust interception are achieved.
[0037] The working principle of the above embodiments is as follows:
[0038] In use, the operator first needs to hoist the aircraft engine to the top of the turntable 9. Then, the cylinder 4 is started, which drives the inspection cover 5 to move vertically downward, so that the aircraft engine is covered inside the inspection cover 5. After the aircraft engine is completely covered by the inspection cover 5, the motor 11 is started. Through the meshing transmission of the first gear 12 and the second gear 13, the rotating shaft 8 is driven to rotate in the opposite direction to the output shaft of the motor 11, so that the aircraft engine rotates continuously on the top of the turntable 9. At this time, the infrared scanning device 6 is turned on, which can automatically scan multiple surfaces and parts of the aircraft engine to check its exterior and confirm whether there is any damage.
[0039] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
