Description

Technical Field

[0001] This invention relates to the field of aircraft maintenance technology, and in particular to a flexible telescopic platform that can automatically conform to the curved surface of the fuselage. Background Technology

[0002] In aircraft maintenance, due to the height of the aircraft fuselage, maintenance personnel cannot stand directly on the ground to complete the inspection, maintenance, and upkeep of various parts of the fuselage. Therefore, a maintenance platform is needed as an operational support to allow maintenance personnel to approach the areas of the fuselage to be inspected and smoothly carry out various maintenance operations, ensuring the efficiency and safety of the maintenance work. The aircraft fuselage profile is irregular, and the shape of the fuselage arc surface and end face varies significantly between different aircraft models. Even different parts of the same aircraft model exhibit complex curved surface features. Most existing aircraft maintenance platforms are integral rectangular structures with flat ends, which cannot adaptively adjust to the irregular arc surface of the aircraft fuselage. This results in gaps between the platform ends and the aircraft fuselage, leading to insufficient fit. This not only affects the ease of operation for maintenance personnel, making some fuselage areas difficult to access and reducing maintenance efficiency, but may also pose safety hazards to maintenance personnel due to unstable fit between the platform and the fuselage. Consequently, these platforms are not suitable for the maintenance needs of different aircraft models and different fuselage parts. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0004] In view of the problems existing in the above and / or existing flexible telescopic platforms that can automatically conform to the curved surface of the fuselage, the present invention is proposed.

[0005] Therefore, the problem that this invention aims to solve is that the flat end of the rectangular platform used for aircraft maintenance cannot adaptively fit the irregular curved surface of the aircraft fuselage, resulting in poor adaptability and affecting maintenance safety.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a flexible telescopic platform that can automatically conform to the arc surface of the machine body, comprising a main body component including an outer tube, an inner tube slidably disposed inside the outer tube, wooden boards fixed on both the outer tube and the inner tube, an electric motor fixed inside the outer tube, a lead screw fixed at the output end of the electric motor, and the lead screw being threadedly connected to the inner wall of the inner tube; The inner tube contains five nylon rods and three steel plates.

[0007] As a preferred embodiment of the flexible telescopic platform that can automatically conform to the curved surface of the machine body according to the present invention, both the outer tube and the inner tube are made of aluminum profiles.

[0008] As a preferred embodiment of the flexible telescopic platform that can automatically conform to the curved surface of the machine body according to the present invention, it further includes an installation component, which is disposed on one side of the inner tube and includes an installation member. The installation member includes an installation block fixed to the end of the inner tube. A pressure sensor is disposed inside the installation block. A connecting sleeve is fixed to one side of the installation block and can be inserted into the installation block.

[0009] The beneficial effects of this invention are as follows: The telescopic unit is composed of inner and outer tubes, a motor, and a pressure sensor. When working, the motor drives the lead screw to rotate. The lead screw rotates inside the inner tube, which can drive the inner tube to extend or retract independently. The inner tube of the telescopic unit can adaptively adjust the extension length according to the arc shape of the aircraft fuselage at the corresponding position, thereby eliminating the gap between the platform and the fuselage, making it easier for maintenance personnel to approach the various maintenance areas of the fuselage, and improving maintenance efficiency.

[0015] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0018] Example 1, referring to Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a flexible telescopic platform that can automatically conform to the curved surface of the machine body. The flexible telescopic platform that can automatically conform to the curved surface of the machine body includes a main body component 1, including an outer tube 13. An inner tube 14 is slidably disposed inside the outer tube 13. Wooden boards 131 are fixed on both the outer tube 13 and the inner tube 14. An electric motor 16 is fixed inside the outer tube 13. A lead screw 15 is fixed to the output end of the electric motor 16. The lead screw 15 is threadedly connected to the inner wall of the inner tube 14.

[0019] An inner tube 14 is slidably installed inside the outer tube 13. A groove corresponding to the inner tube 14 is opened on the outer tube 13. Wooden boards 131 are fixed on both the outer tube 13 and the inner tube 14. The wooden boards 131 are located above the outer tube 13 and the inner tube 14. The maintenance personnel stand on the wooden boards 131 and drive the lead screw 15 to rotate through the motor 16. The lead screw 15 rotates inside the inner tube 14, causing the inner tube 14 to extend and retract. This allows the inner tube 14 to slide inside the outer tube 13. The inner tube 14 drives the mounting block 211 to move. The pressure sensor 213 and the connecting sleeve 212 on the mounting block 211 move, causing the connecting sleeve 212 to contact the object. The connecting sleeve 212 squeezes and transmits pressure to the pressure sensor 213. Any point on its surface can trigger an alarm. Even a small force will trigger an alarm. The inner tube 14, the outer tube 13, the pressure sensor 213, the motor 16, and the lead screw 15 together constitute a telescopic unit. Several telescopic units are set on the platform, which together form a flexible telescopic platform.

[0020] When the inner tube 14 slides outward under the control of the motor 16 and the lead screw 15, the connecting sleeve 212 will first contact the aircraft end face. The connecting sleeve 212 will squeeze and transmit the pressure to the pressure sensor 213. The pressure sensor 213 will feed back the received signal to the control mechanism. The control mechanism will send a stop signal to the motor 16, and the inner tube 14 will stop sliding, thus completing a single telescopic adjustment. After all the inner tubes 14 have moved individually, the ends of all the inner tubes 14 will fit against the arc surface of the aircraft fuselage, thereby filling the gap between the rectangular part of the platform and the aircraft fuselage, making it easier for maintenance personnel to access the various maintenance areas of the fuselage and improving maintenance efficiency.

[0021] Nylon rods 141 and steel plates 142 are fixed in the inner tube 14. There are five nylon rods 141 and three steel plates 142. The nylon rods 141 can contact the inner wall of the groove corresponding to the inner tube 14 inside the outer tube 13. The nylon rods 141 are used to reduce the friction between the inner wall of the groove of the outer tube 13 and the inner tube 14. The steel plates 142 are used to increase the rigidity of the inner tube 14.

[0022] Example 2, refer to Figures 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0023] Specifically, both the outer tube 13 and the inner tube 14 are made of aluminum profiles, which have high strength and are lightweight.

[0024] Specifically, the mounting component 2 is located on one side of the inner tube 14 and includes a mounting piece 21. The mounting piece 21 includes a mounting block 211 fixed to the end of the inner tube 14. A pressure sensor 213 is installed inside the mounting block 211. A connecting sleeve 212 is fixed to one side of the mounting block 211. The connecting sleeve 212 can be inserted into the mounting block 211. The mounting block 211 has a mounting groove corresponding to the connecting sleeve 212. The mounting groove has a T-shaped cross section, and the connecting sleeve 212 has a corresponding shape. The connecting sleeve 212 is fixed to the mounting block 211 by screws.

[0025] In use, the motor 16 drives the lead screw 15 to rotate. The rotation of the lead screw 15 causes the inner tube 14 to slide outward. The connecting sleeve 212 will first contact the aircraft end face. The connecting sleeve 212 squeezes and transmits the pressure to the pressure sensor 213. The pressure sensor 213 feeds back the received signal to the control mechanism. The control mechanism sends a stop signal to the motor 16, and the inner tube 14 stops sliding, thus completing a single telescopic adjustment. After all the inner tubes 14 have moved individually, the ends of all the inner tubes 14 will fit against the arc surface of the aircraft fuselage, thereby filling the gap between the rectangular part of the platform and the aircraft fuselage. This makes it easier for maintenance personnel to access the various maintenance areas of the fuselage and improves maintenance efficiency.

[0026] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
