Description

Technical Field

[0001] This utility model relates to the field of aircraft surface repair technology, and more specifically, to an auxiliary device for repairing composite materials on aircraft surfaces. Background Technology

[0002] An airplane is a heavier-than-air aircraft with wings and one or more engines, capable of flying in the atmosphere under its own power. It typically consists of a fuselage, wings, engines, and tail. During flight, the surface of an airplane may suffer some damage, requiring repair materials. For example, carbon fiber reinforced plastics are widely used in aircraft structural repair.

[0003] Utility model patent CN221954576U discloses an auxiliary device for the maintenance of composite materials on aircraft surfaces, including a trolley. The trolley includes a base plate, and a movable groove is formed on the upper surface of the base plate. A convex movable platform is slidably connected in the movable groove. The protruding part of the convex movable platform is slidably connected in the movable groove and connected to a displacement driving mechanism. Both sides of the base plate are provided with a linkage balancing mechanism. A lifting platform mechanism is installed on the upper surface of the convex movable platform. Through the linkage balancing mechanism, when the convex movable platform moves, the counterweights on both sides will move in the opposite direction synchronously with the convex movable platform, so that the center of gravity of the device is kept in the middle. This prevents the device from tipping over due to the shift of the center of gravity as the convex movable platform moves, thereby improving the stability and safety during use. However, the above patent still has the following shortcomings: when the device is in use, it relies on multiple locking casters to bear all the weight of the upper part, which will also affect the stability of the device; although the counterweight can be moved by the cooperation of the first toothed plate, the second toothed plate and the linkage gear, it can only be moved to the middle of both sides of the trolley, and the effect of preventing tilting is not good. Therefore, we propose an auxiliary device for the maintenance of aircraft surface composite materials. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide an auxiliary device for the maintenance of composite materials on aircraft surfaces.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] An auxiliary device for repairing composite materials on aircraft surfaces includes a base plate. A convex groove is formed on the top surface of the base plate. A first screw is rotatably connected to the inner cavity of the convex groove. A first motor is fixedly installed at the end of the base plate. The output shaft of the first motor is connected to the end of the first screw via a coupling. A movable seat is threaded onto the outer side of the first screw. The top end of the movable seat extends to the top of the base plate and is fixedly connected to a movable plate. A lifting mechanism is provided on the movable plate. Auxiliary support mechanisms are respectively provided on both sides of the base plate. Multiple storage slots are provided on the bottom surface of the base plate. Multiple electric push rods are fixedly installed on the top surface of the base plate. The output ends of the multiple electric push rods extend into the inner cavity of the storage slots and are fixedly connected to self-locking casters.

[0007] As a preferred embodiment of this utility model, the auxiliary support mechanism includes a transmission groove disposed on the side of the base plate.

Moving blocks are threadedly sleeved on the outer sides of the two second screws. Transmission frames are rotatably connected to the sides of the two moving blocks. The ends of the two transmission frames extend to the outside of the base plate and are rotatably connected to support blocks. The bottom surface of the support blocks is flush with the bottom surface of the base plate.

[0008] As a preferred embodiment of this utility model, the lifting mechanism includes multiple electro-hydraulic rods fixedly installed on the top surface of the movable plate. A maintenance basket is fixedly connected to the top of the multiple electro-hydraulic rods. A gate is hinged to the side of the maintenance basket. A ladder is provided on the side of the maintenance basket. A control panel is fixedly installed on the inner wall of the maintenance basket.

[0012] In a preferred embodiment of this utility model, the top and bottom surfaces of the inner cavity of the transmission groove are respectively attached to the top and bottom surfaces of the inner cavity of the moving block.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) In this utility model, by using the storage groove, electric push rod and self-locking casters together, when the device moves, the electric push rod drives the self-locking casters to move down, and the self-locking casters and electric push rod support the base plate, so that the self-locking casters can move the device. When the device moves to below the aircraft repair area, the electric push rod drives the self-locking casters to move up and retract into the inner cavity of the storage groove, so that the bottom surface of the base plate contacts the ground, and the device is directly supported by the base plate to ensure the stability of the device.

[0015] (2) In this utility model, two dual-axis motors can drive four second screws to rotate. The threaded engagement between each second screw and each pair of moving blocks drives the two moving blocks to move closer to each other. The engagement between the two moving blocks and the two transmission frames drives the support block to move outward. The support block, transmission frame, and moving block increase the contact range between the base plate and the ground, ensuring the stability of the device. Attached Figure Description

Both moving blocks 15 are provided with screw holes that are compatible with the second screws 14, ensuring that the second screws 14 and the moving blocks 15 can be smoothly transmitted.

[0030] For details, please refer to Figure 1 and Figure 3 The lifting mechanism 7 includes multiple electric hydraulic rods 18 fixedly installed on the top surface of the movable plate 6. A maintenance basket 19 is fixedly connected to the top of the multiple electric hydraulic rods 18. A gate 20 is hinged to the side of the maintenance basket 19.

[0033] In this embodiment, the storage battery 24 is used to power the control panel 21, the electric push rod 10, the first motor 4, the electric hydraulic rod 18, and the dual-axis motor 13.

[0034] For details, please refer to Figure 1 A pusher 23 is fixedly installed at the end of the base plate 1.

[0035] In this embodiment, the device can be pushed by holding the pusher 23.

[0036] For details, please refer to Figure 1 and Figure 3The side of the movable seat 5 is in contact with the inner wall of the convex groove 2, and the bottom surface of the movable plate 6 is in contact with the top surface of the base plate 1.

[0037] In this embodiment, the inner wall of the convex groove 2 is used to limit the movable seat 5, so that the movable seat 5 can only move along the axial direction of the first screw 3.

[0040] Working principle: In use, firstly, multiple electric push rods 10 are activated to drive multiple self-locking casters 11 to extend from the inner cavity of the storage slot 9. The self-locking casters 11 and electric push rods 10 support the base plate 1. Then, the push handle 23 is used to push the device to move it below the area to be repaired on the aircraft surface. Next, the electric push rods 10 are activated to move the self-locking casters 11 upwards and retract them into the inner cavity of the storage slot 9. At this point, the bottom surface of the base plate 1 contacts the ground, directly supporting the device. Then, two dual-axis motors 13 are activated to drive four second screws 14 to rotate. The threaded engagement between the second screws 14 and two moving blocks 15 drives the two moving blocks... The two moving blocks 15 and the two transmission frames 16 move closer together, and the support block 17 moves outward by cooperating with each other. The support block 17, transmission frame 16 and moving block 15 increase the contact range between the base plate 1 and the ground, ensuring the stability of the device. Finally, the staff climbs up the ladder 22 to the maintenance basket 19 and starts the electric hydraulic rod 18 to move the maintenance basket 19 and the staff upward for aircraft repair. In addition, the first motor 4 can be started to drive the first screw 3 to rotate. Through the threaded engagement between the first screw 3 and the moving seat 5, the moving seat 5, the moving plate 6 and the maintenance basket 19 move laterally, thereby changing the position for repairing the aircraft surface.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
