Description

Technical Field

[0001] This utility model belongs to the field of aircraft maintenance auxiliary technology, specifically an auxiliary support device for aircraft maintenance cabin doors. Background Technology

[0002] During aircraft maintenance, the stable support and fixation of cabin doors is a crucial step. Traditional methods of supporting cabin doors often rely on manual operation, such as using jacks and brackets for temporary support. This method is not only cumbersome and inefficient, but also makes it difficult to ensure the stability and safety of the cabin door during maintenance. Especially when performing internal or external maintenance on the cabin door, if the door cannot be effectively supported and fixed, it is prone to accidental movement, posing safety hazards to maintenance personnel and potentially leading to the interruption or failure of maintenance work.

[0003] Furthermore, with the development of the aircraft manufacturing industry, the size, weight, and shape of cabin doors are becoming increasingly diverse, and the requirements for support and fixing devices are also becoming higher. Traditional support methods are often difficult to adapt to different models and sizes of cabin doors, and cannot meet the diverse needs of modern aircraft maintenance. Utility Model Content

[0004] To address the problems existing in the background art, this utility model provides an auxiliary support device for aircraft maintenance hatches.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary support device for aircraft maintenance cabin doors, comprising a vehicle body, a cylinder, a base plate, a fixing frame, an adsorption mechanism, and two buffer mechanisms;

[0006] The upper end of the vehicle body is fixedly connected to the cylinder body, the telescopic end of the cylinder is fixedly connected to the base plate, the upper end of the base plate is provided with two buffer mechanisms, the two buffer mechanisms are symmetrically arranged, the fixed frame is fixedly connected to the base plate and located between the two buffer mechanisms, and the fixed frame is provided with an adsorption mechanism.

[0007] Each of the aforementioned buffer mechanisms includes a sleeve, a telescopic rod, a spring, an L-shaped plate, and a rubber pad;

[0008] The lower end of the sleeve is fixedly connected to the base plate, and the upper end of the sleeve is slidably connected to the telescopic rod. The telescopic rod is fixedly connected to the L-shaped plate, and a rubber pad is fixed on the L-shaped plate. The spring is fitted onto the telescopic rod, with one end of the spring fixedly connected to the sleeve and the other end of the spring fixedly connected to the lower end of the L-shaped plate.

[0009] The adsorption mechanism includes a branching hose, a vacuum pump, multiple torsion springs, multiple movable plates, multiple suction cups, and multiple corrugated pipes.

[0010] The multiple movable plates are arranged side by side from top to bottom and are hinged by torsion springs. A corrugated pipe is fixed between every two adjacent movable plates. The movable plate at the bottom is fixedly connected to the fixed frame. Two suction cups are fixed on each movable plate. Each suction cup is connected to a vacuum pump through a branching hose. The vacuum pump is fixed on the fixed frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Improved maintenance efficiency and convenience: This utility model, through the design of the vehicle body, enables the entire device to move easily and flexibly on the ground, ensuring accurate alignment with the aircraft door position, greatly improving the efficiency and convenience of maintenance work.

[0013] 2. Protect the hatch from damage: The buffer mechanism in this device effectively absorbs and disperses the pressure generated when the device comes into contact with the hatch through the design of springs and rubber pads, preventing damage to the hatch; at the same time, the soft material of the rubber pads also increases the comfort of contact with the hatch, further protecting the hatch surface.

[0014] 3. High adaptability and stability: The multiple movable plates in the adsorption mechanism are hinged by torsion springs, which can flexibly adapt to the curved shape of the hatch outer wall, ensuring that the entire adsorption mechanism maintains structural stability and integrity when fitting against the hatch. In addition, the bellows connection ensures the stability between the movable plates and the structural integrity, enhancing the overall adaptability.

[0015] 4. Ensure a safe and stable maintenance process: By starting the vacuum pump, a negative pressure is formed inside the suction cup, which adheres tightly to the outer wall of the hatch, ensuring that the hatch remains stable and immobile during maintenance. This provides a safe and reliable working environment for maintenance personnel and reduces the risks and safety hazards during the maintenance process.

[0016] In summary, this utility model demonstrates significant beneficial effects in improving maintenance efficiency, protecting hatches, adapting to different curved surface shapes, and ensuring the safety and stability of the maintenance process. Attached Figure Description

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0020] This embodiment describes an auxiliary support device for an aircraft maintenance hatch, including a vehicle body 1, a cylinder 2, a base plate 3, a fixing frame 9, an adsorption mechanism, and two buffer mechanisms.

[0021] The upper end of the vehicle body 1 is fixedly connected to the cylinder body of the cylinder 2, the telescopic end of the cylinder 2 is fixedly connected to the base plate 3, the upper end of the base plate 3 is provided with two buffer mechanisms, the two buffer mechanisms are symmetrically arranged, the fixing frame 9 is fixedly connected to the base plate 3 and located between the two buffer mechanisms, and the fixing frame 9 is provided with an adsorption mechanism.

[0022] Each of the aforementioned buffer mechanisms includes a sleeve 4, a telescopic rod 5, a spring 6, an L-shaped plate 7, and a rubber pad 8;

[0023] The lower end of the sleeve 4 is fixedly connected to the base plate 3, and the upper end of the sleeve 4 is slidably connected to the telescopic rod 5. The telescopic rod 5 is fixedly connected to the L-shaped plate 7, and a rubber pad 8 is fixed on the L-shaped plate 7. The spring 6 is fitted on the telescopic rod 5, one end of the spring 6 is fixedly connected to the sleeve 4, and the other end of the spring 6 is fixedly connected to the lower end of the L-shaped plate 7.

[0024] The adsorption mechanism includes a branching hose 13, a vacuum pump 14, multiple torsion springs, multiple movable plates 10, multiple suction cups 11, and multiple corrugated pipes 12.

[0025] The multiple movable plates 10 are arranged side by side from top to bottom and are hinged by torsion springs. A bellows 12 is fixed between every two adjacent movable plates 10. The movable plate 10 at the bottom is fixedly connected to the fixed frame 9. Two suction cups 11 are fixed on each movable plate 10. Each suction cup 11 is connected to a vacuum pump 14 through a branch hose 13. The vacuum pump 14 is fixed on the fixed frame 9.

[0026] When using this invention, firstly, the operator uses the mobility of the vehicle body 1 to easily push the entire device directly under the aircraft door to be inspected. The design of the vehicle body 1 facilitates flexible movement on the ground, ensuring that the device can be accurately aligned with the door position. Subsequently, the cylinder 2 is activated, which pushes the base plate 3 to rise smoothly. The two buffer mechanisms at its upper end also move closer to the lower end of the aircraft door. When the rubber pad 8 on the L-shaped plate 7 contacts the lower end of the door, a certain pressure is generated. At this time, the spring 6 plays a buffering role, absorbing and dispersing this pressure to prevent damage to the door. At the same time, the soft material of the rubber pad 8 also increases the comfort of contact with the door, further protecting the door surface. After the base plate 3 and the buffer mechanism successfully lift the door, the adsorption mechanism begins to function. Each movable plate 10, with its torsion spring hinge design, can flexibly adapt to the curved shape of the hatch outer wall. As the movable plate 10 is attached, the suction cups 11 fixed on it gradually come into close contact with the hatch outer wall. The bellows 12 play a crucial role here, connecting adjacent movable plates 10 to ensure that the entire adsorption mechanism maintains structural stability and integrity when adhering to the hatch. Finally, the vacuum pump 14 is started. The vacuum pump 14 is connected to each suction cup 11 through the branch hose 13 and begins to extract air from the suction cups. As the air is gradually removed, a negative pressure is formed inside the suction cup 11, thus adhering tightly to the hatch outer wall. This step ensures that the hatch remains stable during maintenance, providing a safe and reliable working environment for maintenance personnel.
