Description

Technical Field

[0001] This utility model relates to the field of aircraft technology, and more specifically, to an aircraft take-off and landing centering device. Background Technology

[0002] The tunnel inspection vehicle drone is a device that integrates drone technology and tunnel inspection functions. It is mainly used for the safety inspection, maintenance and monitoring of tunnels. On the tunnel inspection vehicle drone platform, the drone needs to take off, land and be retrieved automatically. Currently, the tunnel inspection vehicle has a drawer-type drone take-off and landing system. During landing and take-off, the drone is prone to hitting the sides and damaging the propeller. Therefore, it is necessary to design a liftable platform. After the drawer is pulled out, the drone platform is raised to be basically level with the roof of the vehicle. During retrieval, the platform is lowered and the drone is finally retrieved.

[0003] Currently, drones often experience errors in landing point positioning during the recovery phase. Therefore, a centering mechanism is needed to center the drone's position and fix it in place before finally recovering and transporting it. Additionally, the strong downward impact force during drone landing can affect the stability of the landing platform at a certain height. Utility Model Content

[0029] Please see Figures 1-5 A landing and centering device for an aircraft includes a landing platform 1, a support platform 2, guide frames 3 symmetrically arranged on the support platform 2, a drive device and a landing platform 4, a guide plate 5 on the landing platform 4, guide grooves 6 that mate with the guide plates 5 on the guide frames 3, limit holes 7 arrayed on the guide grooves 6, limit blocks 8 on the limit holes 7, and snap-fit ​​grooves 9 on the limit blocks 8. Snap-fit ​​springs 10 and snap-fit ​​blocks 11 are located within the snap-fit ​​grooves 9, with the bottom of the snap-fit ​​blocks 11 being an inclined surface. A positioning frame 12 is provided on the landing platform 4, a positioning screw 13 rotatably mounted on the positioning frame 12, a positioning motor 14 at one end of the positioning screw 13, a positioning block 15 rotatably mounted on the positioning screw 13, a landing plate 16 on the positioning block 15, and a crosshair 17 on the landing plate 16. The drive device includes a drive frame 23. A drive screw 24 is rotatably mounted on the moving frame 23. The drive screw 24 is threadedly connected to the lifting platform 4. A drive motor 25 is mounted on one end of the drive screw 24. Lifting slots 26 are symmetrically arranged on the lifting platform 4. A lifting screw 27 is rotatably mounted in one of the lifting slots 26. A lifting motor 28 is mounted on one side of the lifting screw 27. A lifting block 29 that cooperates with the lifting screw 27 is mounted on the positioning frame 12. A guide slider 30 is mounted on the positioning frame 12. The guide slider 30 is slidably mounted in another lifting slot 26. Clamping blocks 31 are symmetrically arranged on the falling plate 16. Each clamping block 31 is equipped with a clamping claw 32. Clamping slots 33 are symmetrically arranged on the falling plate 16. A clamping screw 34 is rotatably mounted in the clamping slot 33. The clamping block 31 is located in the clamping slot 33 and is threadedly connected to the clamping screw 34. A clamping motor 35 is connected to one end of the clamping screw 34.

[0030] In this embodiment, during the recovery of the drone, the drive motor 25 is activated, which drives the drive screw 24 to rotate. The drive screw 24 rotates relative to the lifting platform 4, causing the guide plate 5 of the lifting platform 4 to move vertically along the guide groove 6 of the guide frame 3, so that the lifting platform 4 moves to approximately the height of the top of the recovery box. Then, the lifting motor 28 is activated, which drives the lifting screw 27 to rotate. Through the relative rotation of the lifting screw 27 and the lifting block 29, the guide slider 30 moves within the lifting groove 26, adjusting the position of the positioning frame 12. The positioning motor 14 then... The positioning screw 13 is rotated, which in turn moves the positioning block 15 and the landing plate 16, thereby achieving adjustment in any direction in the horizontal direction. The position of the landing plate 16 is adjusted according to the landing position of the drone. When the drone lands on the landing plate 16, the clamping motor 35 is activated. The clamping motor 35 drives the clamping screw 34 to rotate, which in turn drives the clamping block 31 and the clamping claw 32 to fix the position of the drone. Then, the positioning motor 14 and the lifting motor 28 are activated, so that the landing plate 16 and the drone move to the center of the support platform 2. The lifting platform 4 is driven to move downward through the drive device, and the drone is retrieved.

[0031] Please see Figures 4-5 As one embodiment of moving the limiting plate 19: the guide frame 3 is provided with a limiting groove 18, the limiting groove 18 is provided with a limiting plate 19, the limiting plate 19 is fixedly connected to the limiting block 8, the support platform 2 is provided with a moving groove 20, the moving groove 20 is provided with a moving screw 21, the limiting plate 19 extends into the moving groove 20 and is threadedly connected to the moving screw 21, and one end of the moving screw 21 is provided with a moving motor 22.

[0032] More specifically, when the drive device moves the lifting platform 4, the lifting platform 4 moves the guide plate 5 along the guide groove 6. When the guide plate 5 moves upward, it presses the locking block 11 and the locking spring 10. When the guide plate 5 completely passes the locking block 11, the locking block 11 pops out under the elastic force of the locking spring 10, so that it supports the bottom of the guide plate 5, so that it has the effect of preventing falling, thereby dealing with the downward impact when the drone lands, improving the safety of the drone landing. Then, when the lifting platform 4 and the guide plate 5 move downward, the moving motor 22 is started. The moving motor 22 drives the moving screw 21 to rotate. The moving screw 21 drives the limit plate 19 and the limit block 8 to move to both sides, thereby allowing the lifting block 29 to descend smoothly and the drone to be successfully recovered.

[0033] In summary, during the use or operation of the overall equipment: When recovering the drone, the drive motor 25 is activated, which drives the drive screw 24 to rotate. The drive screw 24 rotates relative to the lifting platform 4, causing the guide plate 5 of the lifting platform 4 to move vertically along the guide groove 6 of the guide frame 3, so that the lifting platform 4 moves to approximately the height of the top of the recovery box. Then, the lifting motor 28 is activated, which drives the lifting screw 27 to rotate. Through the relative rotation of the lifting screw 27 and the lifting block 29, the guide slider 30 moves within the lifting groove 26, adjusting the position of the positioning frame 12. Motor 14 drives positioning screw 13 to rotate, which in turn moves positioning block 15 and landing plate 16, thereby achieving adjustment in any direction in the horizontal direction. The position of landing plate 16 is adjusted according to the landing position of the drone. When the drone lands on landing plate 16, clamping motor 35 is activated. Clamping motor 35 drives clamping screw 34 to rotate, which in turn moves clamping block 31 and clamping claw 32 to fix the position of the drone. Then, positioning motor 14 and lifting motor 28 are activated, so that landing plate 16 and drone move to the center of support platform 2. The lifting platform 4 is driven to move downward through the drive device to retrieve the drone.

[0034] When the drive device moves the lifting platform 4, the lifting platform 4 moves the guide plate 5 along the guide groove 6. When the guide plate 5 moves upward, it squeezes the locking block 11 and the locking spring 10. When the guide plate 5 completely passes the locking block 11, the locking block 11 pops out under the elastic force of the locking spring 10, so that it supports the bottom of the guide plate 5, so that it has the effect of preventing fall and thus copes with the downward impact when the drone lands, improving the safety of the drone landing. Then, when the lifting platform 4 and the guide plate 5 move downward, the moving motor 22 is started. The moving motor 22 drives the moving screw 21 to rotate. The moving screw 21 drives the limit plate 19 and the limit block 8 to move to both sides, so that the lifting block 29 descends smoothly and the drone is successfully recovered.
