[0002] An aircraft wing assembly ladder is a specially designed auxiliary device that provides technicians with a safe and convenient operating platform during aircraft manufacturing and maintenance, enabling them to efficiently assemble, inspect, maintain, and repair wings. The design of this ladder must meet the standards and safety requirements of the aviation industry, ensuring that operators remain stable while working at heights and have easy access to all parts of the wing.

[0003] In the assembly and maintenance of aircraft wings, work ladders are a crucial tool for maintenance personnel to perform high-altitude operations, and their safety is of paramount importance. However, existing work ladders typically only have guardrails at the front and sides, lacking necessary protective facilities at the rear. This makes it easy for maintenance personnel to fall accidentally when turning or moving, especially when operating in confined spaces, increasing the risk of safety accidents. Furthermore, due to the lack of a comprehensive protective structure, the overall stability of the work ladder is poor. During complex operations, even a slight sway can lead to accidents, seriously affecting the safety of workers.

[0004] To address the aforementioned issues, it is necessary to design a working ladder for aircraft wing assembly that provides protection for maintenance personnel. Utility Model Content

Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0020] Example: Aircraft wing assembly work ladder, such as Figures 1-5As shown, the system includes a work ladder body 1, casters 2, guide rods 3, a protective plate 4, a mounting block 5, a rotating rod 6, a gear 7, a motor 8, a protective shell 81, a rack 9, a support block 10, a screw 11, a bidirectional motor 12, a push frame 13, a sliding rod 14, a support plate 15, an anti-slip pad 151, an elastic element 16, a guide plate 17, and a pressing rod 18. The work ladder body 1 provides a platform for maintenance personnel to perform high-altitude operations. Casters 2 are symmetrically connected to the bottom of the work ladder body 1, and guide rods 3 are symmetrically connected to the front and rear of the lower side of the work ladder body 1. A protective plate 4 is slidably connected between the rods 3. The protective plate 4 prevents maintenance personnel from falling and provides additional safety protection. The size of the protective plate 4 is designed to fit snugly against the gap between the platform and the stairs on the work ladder body 1. A rack 9 is connected to the lower side of the protective plate 4. Mounting blocks 5 are symmetrically connected to the front and rear sides of the right side of the work ladder body 1. A motor 8 is mounted on the front side of the front mounting block 5. A protective shell 81 is connected to the front side of the front mounting block 5. The protective shell 81 is located outside the motor 8 and can protect the motor 8. The rear end of the output shaft of the motor 8 passes through the front mounting block 5 and is connected to... There is a rotating rod 6, and a gear 7 is connected to the rotating rod 6. The gear 7 meshes with the rack 9. Support blocks 10 are symmetrically connected to the front and rear of the working ladder body 1. A bidirectional motor 12 is installed on the right side of the working ladder body 1. Both output shafts of the bidirectional motor 12 are connected to screws 11. Push frames 13 are slidably connected to both screws 11. The push frames 13 adopt a U-shaped design. The push frames 13 are used to drive the movement of sliding rods 14 and support plates 15. Sliding rods 14 are symmetrically slidably connected to the left and right sides of the push frames 13. Support plates 15 are connected between the bottom ends of the two sliding rods 14 on the same side. The support plate 15 provides stable support to prevent the working ladder body 1 from tipping over. The bottom of both support plates 15 is connected to anti-slip pads 151, which can prevent the support plates 15 from slipping. Two elastic elements 16 are connected between the push frame 13 and the two sliding rods 14. Guide plates 17 are symmetrically connected on the left and right sides of the working ladder body 1. The guide plates 17 are used to guide the movement direction of the pressing rods 18 and ensure that the pressing rods 18 slide along the predetermined path. The pressing rods 18 are connected to the opposite side of the two sliding rods 14. The two pressing rods 18 are in contact with the guide plates 17.

[0021] When this device is needed to repair an aircraft wing, the maintenance personnel push the working ladder, causing the casters 2 to roll until the working ladder is next to the wing requiring repair. Then, the personnel stop pushing the working ladder and start the bidirectional motor 12. The output shafts at both ends of the bidirectional motor 12 drive the two screws 11 to rotate. The two screws 11 drive the push frame 13 on them to move outward. The push frame 13 drives the two sliding rods 14, support plate 15, and pressing rod 18 on it to move outward. When the pressing rod 18 moves to contact the guide plate 17, the pressing rod 18 gradually moves downward along the inclined surface of the guide plate 17. As the pressing rod 18 moves, it drives the sliding rod 14 downward, compressing the elastic element 16. The sliding rod 14 and support plate 15 also move downwards. When the support plate 15 moves to contact the ground, the bidirectional motor 12 is turned off to ensure that the working ladder is stably supported on the ground. Next, the maintenance personnel carry tools and climb up the working ladder to the platform, place the tools properly on the platform, and start the motor 8. The output shaft of the motor 8 drives the rotating rod 6 to rotate, the rotating rod 6 drives the gear 7 to rotate, the gear 7 rotates and contacts the rack 9 and drives it to move upward. The movement of the rack 9 drives the protective plate 4 to move upward. When the protective plate 4 moves to a suitable height, the motor 8 is turned off to provide effective high-altitude operation protection for the maintenance personnel. Then the maintenance personnel begin to use tools to carry out necessary inspections and maintenance work on the aircraft wings.
