Description

Technical Field

[0001] This utility model relates to the field of aircraft canard repair technology, specifically an aircraft canard repair and transportation tooling. Background Technology

[0002] Aircraft canards, typically mounted on the front of the aircraft fuselage, are a crucial component providing lift and enhancing maneuverability, directional stability, and directional control. They are trapezoidal, shell-like, and off-center curved surface structures. Canards are generally manufactured from large-sized, high-strength metal materials, with stringent requirements for surface quality and aerodynamic shape. They are heavy at the wing root, light at the wingtip, and have a center of gravity not at the geometric center. During high-altitude, high-speed flight, canards are subjected to continuous surface air friction forces. Furthermore, during landing, the canard acts as a deceleration device, bearing high levels of air resistance and friction. This leads to structural fatigue and fastener loosening, jeopardizing flight and takeoff / landing safety. Therefore, specialized tooling is required for the maintenance, storage, and relocation of canards during ground maintenance.

[0003] During ground repairs of aircraft, the canard needs to be disassembled from the fuselage to facilitate inspection, non-destructive testing, and repair work. Therefore, it is necessary to design a specialized tooling with high structural conformity and safe, stable, and reliable transportation process to facilitate the parking, transportation, and repair of the canard after it is removed from the aircraft, in order to meet the technical requirements for off-aircraft canard maintenance. Summary of the Invention

[0004] To address the aforementioned problems, this utility model proposes a tooling for repairing and transporting aircraft canards.

[0005] A tooling for repairing and transporting aircraft canards includes a tooling frame, a traction rod connected to the tooling frame via a quick-release pin, and a front support beam and a rear support beam mounted on the tooling frame for supporting and fixing the aircraft canards. The lower part of the tooling frame is equipped with several sets of wheels and stop supports.

[0006] Furthermore, the stop support is fixed by rotating a screw rod to contact the ground.

[0007] Furthermore, the lower end of the front support beam is provided with several sets of rotary handwheels for adjusting the height of the front support beam.

[0008] Furthermore, the cross-sections of the front and rear support beams are curved, possessing an arc that allows them to conform to the canard wing surface.

[0009] The beneficial effects of this utility model are as follows: The front and rear support beams installed above the tooling frame have curved cross-sections with rounded edges, allowing them to fit well with the canard wing surface. Simultaneously, square rubber pads are evenly distributed on both the front and rear support beams to reduce vibration damage to the canard wing surface during transportation and maintenance, ensuring surface quality. Increased friction between the canard wing and the tooling prevents relative sliding, ensuring stable placement and guaranteeing stable and reliable transportation and parking without damage. During parking or maintenance, the quick-release pins can be removed to separate the tow bar from the tooling frame, allowing for independent placement of the tow bar and saving space.

[0012] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below.

[0013] like Figures 1 to 4 As shown, an aircraft canard repair and transportation fixture includes a fixture frame 07, a tow bar 01 connected to the fixture frame 07 via a quick-release pin 02, and a front support beam 08 and a rear support beam 10 mounted on the fixture frame 07 for supporting and fixing the aircraft canard. The quick-release pin 02 is used for the mechanical connection between the tow bar 01 and the fixture frame 07. When long-term storage is required, the tow bar 01 can be separated from the fixture frame 07 by removing the quick-release pin 02. The tow bar 01 can be removed and placed separately, which can save space resources. like Figure 1As shown, the lower part of the tooling frame 07 of this utility model is equipped with several sets of wheels 04 and stop supports 05. The wheels 04 are made entirely of rubber and are used for the movement and shock absorption of the entire tooling. The stop supports 05 are fixed by rotating a screw rod to contact the ground, thus providing fixation and support when the entire tooling is parked.

[0014] like Figure 1 and Figure 2 As shown, the tooling frame 07 is equipped with a steering linkage 03 at the front end to adjust the transport direction. During transport, the steering linkage 03 is manually adjusted and driven to rotate using the traction rod 01. Under the action of the steering linkage 03, the two sets of front wheels installed on the tooling frame 07 turn left and right to achieve direction adjustment during transport.

[0015] like Figure 1 and Figure 2 As shown, the tooling frame 07 is equipped with several sets of steel crossbeams to facilitate support of the front support beam 08 and the rear support beam 10, while also providing overall structural strength. The lower end of the front support beam 08 is equipped with several sets of rotating handwheels 06 for adjusting its height, ensuring that the heights of the front support beam 08 and the rear support beam 10 are consistent. The crossbeams of the front support beam 08 and the rear support beam 10 have curved cross-sections, possessing an arc that allows for better contact with the canard wing surface. The front support beam 08 and the rear support beam 10 are evenly distributed with square rubber pads 11 to reduce vibration damage to the aircraft canard wing during transportation. These rubber pads 11 are made of rubber to reduce vibration damage to the canard wing surface during transportation and maintenance, ensuring the surface quality of the wing surface; simultaneously, they increase the friction between the canard wing and the tooling, preventing relative sliding between the canard wing and the tooling, and ensuring stable placement.

[0016] Both ends of the front support beam 08 and the rear support beam 10 are equipped with limiting blocks 09 to improve the stability of the canard wings. Thick rubber is adhered to the limiting blocks 09, which, through built-in bolts, engage with the front support beam 08 and the rear support beam 10 to adjust their length, ensuring secure placement of the canard wings and preventing damage to the canard end faces during transportation or repair. Since the rear support beam 10 is longer than the front support beam 08, at least one limiting block 09 can also be installed on its middle side end to improve installation stability.

[0017] The rear support beam 10 is provided with a crash guard 12 at one end, which is similar to the shape and size of the aircraft canard. The crash guard can be extended and adjusted to securely fix the canard when it is placed; it can also prevent the canard end face from being bumped during transportation or repair.

[0018] When it is necessary to transport, store, or repair aircraft canards, the specific procedures are as follows: Step 1: Rotate the stop support 05 until it contacts and locks with the ground, then secure the fixture. Extend the limit blocks 09 on the front support beam 08 and the rear support beam 10, as well as the crash barrier 12, along the direction of the installed crossbeam. Step 2: Adjust the two sets of rotating handwheels 06 below the front support beam 08 so that the height of the front support beam 08 and the rear support beam 10 are consistent. Remove the canard from the aircraft, place it flat on the tooling, and adjust the limit block 09 and the anti-collision guardrail 12 to fit it. Step 3: When it is necessary to transport the aircraft canard, the tow bar 01 and the steering linkage 03 are connected by the quick release pin 02, the lifting stop support 05 is rotated and the maintenance personnel drag the tow bar 01 and the drive steering linkage 03 to realize the transportation and steering of the aircraft canard. Step 4: When it is necessary to park the aircraft canard, the quick-release pin 02 is removed to separate the tow bar 01 from the steering linkage 03, saving the space occupied by the tooling; at the same time, the stop support 05 is rotated to lift the wheel 04 off the ground, ensuring the tooling is fixed and preventing the wheel 04 from being deformed by long-term pressure. Step 5: When the canard needs to be repaired, repeat the above steps, secure the tooling, and adjust the two sets of rotating handwheels 06 located below the front support beam 08 to adjust the height of the front support beam 08 to meet the different position requirements during canard repair and facilitate the maintenance work.

[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
