Description

Technical Field

[0001] The utility model relates to the technical field of aircraft manufacturing and maintenance, in particular to an auxiliary mounting bracket for a wing of a light aircraft. Background Art

[0002] Light aircraft, a vital component of aviation, are commonly used in a variety of scenarios, including entertainment, education, aerial photography, and scientific research. Due to their relatively simple structure, flexible operation, and low maintenance costs, light aircraft have garnered widespread attention and application in recent years. Wings, as a key component in the design and manufacture of light aircraft, are crucial for their installation. The wings must not only provide sufficient lift but also ensure precise alignment with the fuselage to ensure stable and safe flight.

[0003] Traditional wing installation methods mostly rely on forklifts or lifting equipment. These devices lift the wing to the same level as the fuselage for docking and installation. Forklifts are typically used for short-distance transport and installation, offering flexibility and convenience. Lifting equipment, on the other hand, is suitable for larger and more complex wing installations. Lifting equipment, such as a crane, is used to lift the wing to the desired height. However, both forklifts and lifting equipment have limitations.

[0004] In existing wing installation processes, while forklifts and lifting equipment can provide the necessary lifting force, accurate installation is difficult to ensure. Due to the wings' large size and weight, even mechanical lifting equipment limits their stability and ability to fine-tune them in mid-air. Consequently, significant manpower is required for position adjustments and corrections during installation. This not only increases installation time and costs but can also lead to errors and safety hazards. Furthermore, because the movement and docking of the wings in mid-air require extremely high precision, manual adjustments are difficult to achieve, further extending the installation period. Utility Model Content

[0005] In order to overcome the shortcomings of limited accuracy and reliance on manpower, the utility model provides a high-accuracy auxiliary mounting bracket for the wing of a light aircraft.

[0006] The invention relates to an auxiliary mounting bracket for a wing of a light aircraft, comprising a main frame, a universal wheel, a support frame, a support rod, a fixed base, a return spring, a limit rod, a clamping block and an adjustment assembly. A plurality of universal wheels are installed at the bottom of the main frame, the main frame is connected to the support frame, a plurality of support rods are slidably connected to the support frame, a plurality of fixed bases are symmetrically connected to the support rods, a plurality of limit rods are slidably connected to the fixed base, the ends of the limit rods connected to the same fixed base are commonly connected to the clamping block, a return spring is sleeved on the limit rod, one end of the return spring is connected to the clamping block, and the other end is connected to the fixed base. An adjustment assembly for adjusting the height and angle of the support frame is provided on the main frame.

[0007] As a further preferred solution, the adjustment component includes an electric push rod, a connecting piece and a controller. Cavities are opened in the columns around the main frame, and an electric push rod is installed in each cavity. The top of the electric push rod is connected to a connecting piece, and the top of the connecting piece is rotatably connected to the support frame. Controllers are installed on the columns around the main frame, and the controller controls each electric push rod individually.

[0008] As a further preferred solution, it also includes a protective pad, and a plurality of protective pads are connected to the upper surface of the support rod.

[0009] As a further preferred solution, it further includes a fastening rubber pad, which is connected to two clamping blocks symmetrically distributed on the support rod, and is located on one side adjacent to the two clamping blocks.

[0010] As a further preferred solution, it further includes a handle, and the support frame is connected to the handle.

[0011] As a further preferred solution, it also includes lighting lamps, and multiple lighting lamps are installed on the top of the support frame.

[0012] The utility model has the following advantages:

[0013] 1. Through the action of the limit rod and return spring, as well as the slidable support rod, the clamping block can adaptively clamp the ribs of the wing, ensuring the stability and accuracy of the wing during installation.

[0014] 2. Through the individually controllable electric push rods, the support frame can be raised in height while its tilt angle can be precisely adjusted to meet the different angle requirements during the wing installation process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to specific embodiments. It should be noted that, unless otherwise specified or limited, terms such as "dispose," "install," "connect," and "connect" should be understood in a broad sense. For example, "connect" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; or it may refer to internal communication between two components. A person skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0021] Embodiment: A light aircraft wing auxiliary mounting bracket, such as Figures 1-4 As shown, it includes a main frame 1, universal wheels 2, support frames 3, support rods 301, fixed bases 4, return springs 5, limit rods 6, clamping blocks 7 and adjustment components. Four universal wheels 2 are installed at the bottom of the main frame 1. The main frame 1 is connected to the support frame 3. Four support rods 301 are slidably connected to the support frame 3. Each support rod 301 is connected to four fixed bases 4. Two limit rods 6 are slidably connected to the fixed base 4. The ends of the limit rods 6 connected to the same fixed base 4 are commonly connected to the clamping blocks 7. The limit rods 6 are all provided with return springs 5. One end of the return spring 5 is connected to the clamping block 7, and the other end is connected to the fixed base 4. The main frame 1 is provided with an adjustment component for adjusting the height and angle of the support frame 3.

[0022] like Figure 1 and Figure 4 As shown, the adjustment component includes an electric push rod 9, a connecting piece 10 and a controller 11. Cavities 8 are opened in the columns around the main frame 1. An electric push rod 9 is installed in each cavity 8. The top of the electric push rod 9 is connected to the connecting piece 10. The top of the connecting piece 10 is a sphere and is rotatably connected to the support frame 3. Controllers 11 are installed on the columns around the main frame 1. Each electric push rod 9 can be individually controlled by the controller 11.

[0023] During the assembly process of the wings of small aircraft, the wing spars are first connected to the trusses of the fuselage to ensure the strength of the wing connection, and then other electronic components of the wing are installed. Finally, the skin is connected to the fuselage and wing by riveting to ensure that the appearance of the aircraft is flat and smooth and meets the aerodynamic performance requirements of the design. The skeleton of the wing is mainly composed of spars and ribs. When installing the wing, the ribs are placed on the support rod 301 and squeezed downward to push the clamping blocks 7 on both sides of the support rod 301 to move, and the limit rod 6 slides on the fixed base 4 to compress the return spring 5. According to the design requirements of the wing skeleton, the support rod 301 is moved left and right, and the support rod 301 slides on the support frame 3 to meet the design requirements of different wings. The clamping and fixation of multiple ribs have been completed, so that the skeleton of the wing can be supported. Then, The main frame 1 is pushed by the universal wheel 2 to align the wing beam with the connection position of the fuselage. During the installation process, if the height and angle of the wing need to be adjusted, the electric push rod 9 is controlled by the controller 11. The four electric push rods 9 cooperate to simultaneously push the support frame 3 up or down, thereby adjusting the position and overall height of the wing relative to the main frame. By controlling a certain electric push rod 9 separately to lift one end of the support frame 3, the connecting member 10 rotates in the support frame 3, which can change the inclination angle of the support frame 3, thereby changing the inclination angle of the wing to facilitate the installation of the wing. Since the wing as a whole has a movable arc, the wing can be pushed left and right, and the wing can change the axial rotation angle. At the same time, the slidable support rod 301 can push the wing along the axial direction of the wing, and the wing can achieve various postures, and finally cooperate to complete the installation of the wing.

[0024] like Figure 3 As shown, a protection pad 12 is also included, and a plurality of protection pads 12 are connected to the upper surface of the support rod 301.

[0025] The protection pad 12 can buffer the compression between the rib of the wing and the support rod 301. The compressed protection pad 12 can increase the force-bearing area of ​​the rib, thereby reducing the deformation of the rib.

[0026] like Figure 3 As shown, a fastening rubber pad 13 is also included. The two clamping blocks 7 symmetrically distributed on the support rod 301 are connected with the fastening rubber pad 13. The fastening rubber pad 13 is located on one side adjacent to the two clamping blocks 7.

[0027] The flexible fastening rubber pad 13 isolates the clamping block 7 from the rib, thereby reducing damage to the rib caused by the clamping block 7. At the same time, the fastening rubber pad 13 with a certain thickness can also supplement the elastic force of the reset spring 5 to maintain the clamping force on both sides of the rib.

[0028] like Figure 1 As shown, a handle 14 is also included, and the support frame 3 is connected to the handle 14.

[0029] If the overall length of the wing is greater than the supporting frame 3 , the staff member holds the handle 14 and pushes the main frame 1 to move.

[0030] like Figure 1 As shown, it also includes lighting lamps 15, and multiple lighting lamps 15 are installed on the top of the support frame 3.

[0031] When fixing or installing the wing, the lighting lamp 15 can provide a good visual environment and ensure a good working environment.

[0032] When installing the wing, first place the wing rib on the support rod 301. The support rod 301 is connected to the support frame 3 by sliding. It can be moved left and right according to the design requirements of the wing to adapt to the spacing of different wing ribs. When the rib is placed on the support rod 301, it will push the clamping blocks 7 on both sides. The clamping blocks 7 slide on the fixed base 4 through the limit rod 6 and compress the return spring 5, thereby clamping the fixed wing rib. The protection pad 12 is set on the upper surface of the support rod 301 to buffer the extrusion between the wing rib and the support rod 301 and reduce the deformation of the rib. At the same time, the fastening rubber pad 13 is connected to the clamping block 7, which reduces the clamping block 7. The damage to the ribs is supplemented by the elastic force of the return spring 5, maintaining a stable clamping force. On the main frame 1, the electric push rod 9 is connected to the support frame 3 through a connector 10. The controller 11 can control each electric push rod 9 individually, thereby adjusting the tilt angle of the support frame 3 while raising its height, meeting the angle adjustment requirements during the wing installation process. In addition, the support frame 3 is also equipped with a handle 14, which is convenient for the staff to move the entire installation bracket when the overall length of the wing exceeds the support frame 3. The lighting 15 is installed on the top of the support frame 3 to provide sufficient lighting for the wing fixation and installation process, ensuring a good working environment. Through the coordinated work of these components, the wing skeleton can be effectively supported, angle adjusted, and conveniently moved, and the wing installation is finally completed.
