Description

Technical Field

[0001] This utility model relates to the field of wing inspection technology, and more specifically, to a wing inspection device for aircraft maintenance. Background Technology

[0002] In the prior art, such as Chinese utility model patent with publication number CN221852201U, a wing inspection device for aircraft maintenance is disclosed. It can not only improve inspection efficiency and eliminate the need for manual flipping, but also the clamping mechanism can clamp wings of different sizes, thus improving the applicability of the device.

[0003] However, the above technical solutions still have the following shortcomings:

[0004] 1. Directly inserting the wings into the testing equipment requires an additional cleaning process, which increases the overall testing time and affects work efficiency.

[0005] 2. Fixing the wings by clamping creates blind spots for inspection, making it impossible to conduct comprehensive inspections.

[0006] To address the aforementioned problems, this application proposes a wing inspection device for aircraft maintenance. Utility Model Content

[0007] The purpose of this invention is to provide a wing inspection device for aircraft maintenance, thereby solving the problems in the prior art.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] An aircraft wing inspection device for maintenance includes a fuselage, wherein two inspection instruments are mounted inside the right end of the fuselage.

[0010] The machine body is equipped with a support roller and a lifting roller that can be raised and lowered, and the support roller and the lifting roller are parallel to each other vertically.

[0011] A cleaning belt is provided between the left and right adjacent support rollers, which is divided into three groups: left, middle and right. These groups are a foam cleaning unit, a water washing cleaning unit and a scraping and adsorption unit, which respectively perform foam cleaning, water washing cleaning and adsorption cleaning.

[0012] Both the foam cleaning unit and the water washing cleaning unit have hollow cavities inside, and the hollow cavity has permeation holes inside the side wall near the wing.

[0013] The cleaning belt is equipped with lifting mechanisms at both ends, and the cleaning belt can be elastically bent and deformed.

[0014] Preferably, the two ends of the support roller are connected to the transmission seats on the front and rear sides of the machine body, the two ends of the lifting roller are equipped with lifting seats, and the upper end of the lifting seat is equipped with an electric telescopic mechanism that is fixedly connected to the top of the machine body.

[0015] Preferably, the side of the cleaning strip is machined into an inclined scraper to create a scraping effect when it comes into contact with the wing.

[0016] Preferably, both ends of the foam cleaning unit and the water washing cleaning unit are equipped with hoses that connect to a water tank installed above or inside the machine body.

[0017] Preferably, the cleaning belts are arranged in pairs, symmetrical vertically and staggered horizontally.

[0018] Preferably, both ends of the cleaning belt are fixed with side seats, and a swivel sleeve is rotatably installed on the upper end of the side seat. A ball screw is connected inside the swivel sleeve, and the upper end of the ball screw is connected to the transmission seat above the machine body.

[0019] Preferably, elastic pads are installed on the outer sides of the support roller and the lifting roller.

[0020] The beneficial effects of this utility model are:

[0021] 1. By dividing the airfoam cleaning unit, water washing cleaning unit and scraping adsorption unit into zones, the airfoam, water and scraping adsorption are used to clean the airfoam and airfoam, thereby avoiding misjudgment due to some impurities. This not only improves the detection accuracy, but also simplifies the process and reduces the overall time consumption.

[0022] 2. By using the clamping and rolling conveying of lifting rollers and support rollers, different areas of the wing are sequentially inspected by the detector, thus achieving inspection without blind spots. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] An aircraft wing inspection device is designed for inspecting defects such as cracks on aircraft wings. By linking foaming, washing, wiping and inspection operations in a zoned manner, it can enter the inspection area immediately after the wing is cleaned, thereby avoiding misjudgment due to impurities. It can save additional cleaning and transportation processes, improve the accuracy of inspection, and achieve a blind-spot-free inspection effect through continuous conveying.

[0033] In some embodiments, the specific structure of the wing inspection device for aircraft maintenance is as follows: Figure 1-4 As shown, it includes the fuselage 1 and its internal three-zone cleaning mechanism;

[0034] The machine body 1 also includes a transmission seat 11 and a water tank 12 installed on the top, as well as a transmission seat 2 13 installed on the front and rear sides. Two detectors 14 are installed inside the right end of the machine body 1.

[0035] It should be noted that the detector 14 is an optical imaging detector or an ultrasonic flaw detector, which is driven by a lifting motor to move vertically to meet the inspection needs of wings of different thicknesses.

[0036] Support rollers 211 are installed inside the machine body 1 and are distributed at equal intervals laterally, corresponding to the machine body 1.

[0037] The fuselage 1 is also equipped with a lifting roller 212, which is located above the support roller 211. The two together clamp the wing.

[0038] Furthermore, a lifting seat 213 is installed at the upper end of the lifting roller 212, and its upper end is connected to the top of the machine body 1;

[0039] It should be noted that rubber pads are installed on the outer sides of both the support roller 211 and the lifting roller 212 to increase frictional resistance and protect the wings from damage.

[0040] It is understandable that the support roller 211 and the lifting roller 212 form a clamp, and the clamping distance is adjusted by the lifting seat 213 to achieve the clamping and conveying effect of different types of wings;

[0041] The machine body 1 is equipped with cleaning belts 22, which are divided into three groups from left to right and located in three areas. Each group is located between adjacent support rollers 211.

[0042] It should be noted that the cleaning belt 22 is made of elastic composite material, which has a certain degree of bending recovery. It has a reinforcing fiber layer on the inner side and a microporous structure on the outer side to facilitate the seepage of cleaning agent.

[0043] Each set of cleaning belts 22 includes two belts, one above the other, which are staggered left and right, and the two ends of the cleaning belts 22 are vertically adjustable.

[0044] Furthermore, the cleaning strips 22 in the three areas from left to right are a foam cleaning unit 221, a water washing cleaning unit 222, and a scraping and adsorption unit 223, respectively.

[0045] Furthermore, both the foam cleaning unit 221 and the water washing cleaning unit 222 have hollow cavities 2212 inside, and permeation holes 2213 are provided inside the body between the hollow cavity 2212 and the side of the foam cleaning unit 221.

[0046] It is understandable that when the two ends of the cleaning belt 22 rise and fall, the body bends, thus adhering to the outer side of the wing. The squeezing force formed by the adhering causes the foam cleaner or water in the hollow cavity 2212 to overflow to the wing surface, thereby forming foam cleaning or water washing cleaning.

[0047] like Figure 3As shown, both ends of the cleaning belt 22 are fixed with side seats 23. Two screw sleeves 231 are rotatably installed on the upper end of the side seats 23. The screw sleeves 231 are fitted with ball screws 2311 inside, and their upper ends are fixedly connected to the top of the machine body 1.

[0048] It should be noted that the ball screw 2311 is driven by the servo motor inside the transmission seat 11 to achieve precise lifting control of the cleaning belt 22, ensuring the fit with the wing surface.

[0049] The upward extension of the swivel sleeve 231 increases the engagement length with the ball screw 2311, which can prevent wing cleaning agent foam and water from falling into the connection between the swivel sleeve 231 and the ball screw 2311.

[0050] like Figure 3 As shown, the cleaning belt 22 located at the top has hoses 2201 installed at both ends, with the upper end passing through the body 1 and the transmission seat 11 and connecting to the connecting pipe 15 on one side of the water tank 12.

[0051] Among them, the cleaning belt 22 located at the bottom has hoses 2201 at both ends that extend downwards and connect to the transmission seat 11 inside the main body 1.

[0052] It should be noted that there are two water tanks 12, located on one side of the transmission base 11. They store foam cleaning agent and clean water respectively, which are delivered to the corresponding cleaning unit through the pump body via the connecting pipe 15 and the hose 2201.

[0053] like Figure 4 As shown, the sides of the cleaning belt 22 are all inclined scrapers 2211, which are used to scrape off impurities from the surface of the wing as it moves.

[0054] The specific usage methods of the aircraft maintenance wing inspection device, as disclosed in some publications, are as follows:

[0055] S1. The wing is fed between the support roller 211 and the lifting roller 212 to form a clamp, and the support roller 211 and the lifting roller 212 are driven to rotate by the transmission seat 213 and the lifting seat 213 respectively, thereby realizing the conveying of the wing from left to right.

[0056] S2. The wing moving to the right first enters the area where the foam cleaning unit 221 is located. Through the cooperation of the screw sleeve 231 and the ball screw 2311, the two ends of the upper foam cleaning unit 221 in a set move downward and the two ends of the lower foam cleaning unit 221 move upward, so that the middle section of the foam cleaning unit 221 bends and fits the wing.

[0057] S3, the transmission seat 11 delivers foam cleaning agent to the foam cleaning unit 221 through the connecting pipe 15 and the hose 2201, filling the interior of the hollow cavity 2212. Under pressure, the foam cleaning agent overflows outward through the permeation hole 2213 to the surface of the wing, thereby achieving foam cleaning.

[0058] S4. Similar to S2 and S3, the wing is washed and cleaned in the area where the water washing and cleaning unit 222 is located. Finally, the wing is scraped and adsorbed by the scraping and adsorption unit 223 to remove impurities, foam and water.

[0059] S5. During the foam cleaning, water washing cleaning and adsorption cleaning process, impurities are scraped off using scraper 2211.

[0060] S6. The wing enters the area where 114 is located, and the two detectors 14 at the top and bottom simultaneously perform defect detection.

[0061] S7. The wing continues to move to the right until it moves out of the fuselage 1.
