Description

Technical Field

[0001] This utility model relates to the field of aircraft coating repair technology, specifically to a rapid repair and maintenance device for aircraft coatings. Background Technology

[0002] Aircraft coatings refer to one or more layers of special materials that cover the surface of an aircraft. They are not simply paint, but a functional material system made of various components according to specific formulas and processes. They are applied to the surface of aircraft metal or composite materials through processes such as spraying and brushing.

[0003] During flight, aircraft are exposed to various adverse weather conditions, such as friction from raindrops and snowflakes at high speeds, ultraviolet radiation, temperature fluctuations, and humid environments. These factors can accelerate the aging of aircraft coatings or cause corrosion. Furthermore, improper maintenance procedures, such as using incorrect cleaning agents or tools, can also damage the coating. Coating damage not only affects the aircraft's appearance but can also reduce its aerodynamic performance, increase drag, impair stability and handling, and even threaten flight safety.

[0004] However, in practical applications, existing aircraft coating repair devices have shortcomings in terms of position adjustment during the repair and maintenance of aircraft coatings. They are unable to adapt to the repair needs of aircraft coating damage in different locations and shapes. For example, the spraying components of some devices are in fixed positions and cannot be flexibly adjusted according to the specific location of the damaged area, resulting in low repair efficiency and difficulty in guaranteeing repair quality.

A spray gun is fixedly installed on the outer side of the installation head. An observation camera is fixedly installed on the upper end of the installation head.

[0008] Preferably, there are two horizontal linear slide rails fixedly installed on both sides of the upper end of the mobile gantry frame, which are symmetrically distributed on both sides of the upper end of the mobile gantry frame. The upper end of the horizontal linear slide rail is limited and fitted with a limiting slide block, and the upper end of the limiting slide block is fixedly installed with a horizontal moving platform.

[0009] Preferably, the second synchronous pulley is rotatably connected to the outer side of the upper end of the movable gantry frame via a bearing seat.

[0010] Preferably, the lifting platform is fixedly installed at the bottom of the lifting screw, and the bottom of the limiting slide rod is fixedly installed on both sides of the upper end of the lifting platform. A first control motor is fixedly installed on the outer side of the upper end of the horizontal moving platform. A first lifting gear is fixedly installed on the lower end of the transmission shaft of the first control motor. A second lifting gear is meshed with the side end of the first lifting gear, and the second lifting gear is fixedly installed on the outer curved surface of the upper end of the internal thread transmission tube.

[0011] Preferably, a control power cabinet and a storage tank for storing repair coating are fixedly installed on both sides of the lower end of the mobile gantry frame, and a high-pressure pump is fixedly connected to the bottom of the storage tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When the repair coating is delivered to the spray gun, the aircraft coating can be repaired by spraying. During the repair, the moving gantry is moved longitudinally by controlling the opening of the gantry. When the moving gantry moves longitudinally, the spray gun is moved longitudinally and adjusted simultaneously. At the same time, the adjustment motor is activated by controlling the opening of the adjustment motor. When the adjustment motor is activated, it will sequentially move the transverse moving table and the limit slide along the upper end of the transverse linear slide rail. When the transverse moving table moves laterally, the spray gun is moved laterally and adjusted simultaneously. Thus, the aircraft coating can be repaired by spraying while the spraying position can be adjusted by longitudinal and transverse linear movement.

[0016] This invention also features a first control motor that, when activated, sequentially drives the internal threaded transmission tube to rotate. This rotation, due to the force generated by the threaded connection, causes the lifting screw to move up and down. This up-and-down movement of the lifting screw causes the lifting platform to move linearly up and down. Simultaneously, this linear movement of the lifting platform causes the spray gun to move linearly up and down. By activating the second control motor, the spray gun is sequentially rotated horizontally. By activating the third control motor, the spray gun and the observation camera are sequentially oscillated up and down. This allows for simultaneous spraying and repair of the aircraft coating, while facilitating vertical linear movement, horizontal rotation, and vertical oscillation to adjust the spraying position, enabling rapid positioning and repair of the aircraft coating.

[0022] Please see Figure 1-3 This utility model provides a technical solution for a rapid repair and maintenance device for aircraft coatings: including a longitudinally linearly moving gantry 1, a control power cabinet 2 and a storage tank 3 for storing repair coatings are fixedly installed on both sides of the lower end of the gantry 1, and a high-pressure pump is fixedly connected to the bottom of the storage tank 3.

[0023] Two horizontal linear slide rails 4 are fixedly installed on both sides of the upper end of the mobile gantry frame 1, symmetrically distributed on both sides of the upper end of the mobile gantry frame 1. The upper end of the horizontal linear slide rail 4 is movably connected to the limiting slide block 5.

An adjusting motor 7 is fixedly installed on the outer side of the upper end of the mobile gantry frame 1. A first synchronous pulley 8 is fixedly installed on the transmission shaft of the adjusting motor 7. An adjusting synchronous belt 9 is driven to the outer end of the first synchronous pulley 8. A second synchronous pulley 10 is driven to the side of the adjusting synchronous belt 9 away from the first synchronous pulley 8. The second synchronous pulley 10 is rotatably connected to the outer side of the upper end of the mobile gantry frame 1 by bearing seat support. The upper end of the adjusting synchronous belt 9 is fixedly installed on the outer side of the lower end of the horizontal moving platform 6. A through slot 11 is opened through the middle of the upper end of the mobile gantry frame 1. A threaded transmission tube 12 is rotatably connected through a pivot in the middle of the transverse moving platform 6. Limiting slide tubes 13 are fixedly installed through both sides of the transverse moving platform 6. There are two limiting slide tubes 13, which are symmetrically distributed on both sides of the transverse moving platform 6. Limiting slide rods 14 are movably connected to the inner wall of the limiting slide tubes 13. Lifting screws 15 are threadedly connected to the inner wall of the threaded transmission tube 12. Lifting platform 16 is fixedly installed at the bottom of the lifting screws 15. The bottom of the limiting slide rods 14 is fixedly installed on both sides of the upper end of the lifting platform 16, so that the lifting platform 16 can be linearly moved and limited by the limiting slide rods 14 and the limiting slide tubes 13. A first control motor 17 is fixedly installed on the outer side of the upper end of the transverse moving platform 6. A first lifting gear 18 is fixedly installed on the transmission shaft part of the lower end of the first control motor 17. A second lifting gear 19 is meshed with the side end of the first lifting gear 18. The second lifting gear 19 is fixedly installed on the outer curved surface of the upper end of the threaded transmission tube 12.

[0024] A second control motor 20 is fixedly mounted on the outer side of the lifting platform 16. A first rotating gear 21 is fixedly mounted on the lower drive shaft of the second control motor 20. A second rotating gear 22 is meshed with the inner side of the first rotating gear 21, and the second rotating gear 22 is rotatably connected to the lower end of the lifting platform 16 via a support pin. A rotating platform 23 is fixedly mounted on the lower end of the second rotating gear 22. A support frame 31 is fixedly mounted on the lower end of the rotating platform 23. A swing shaft 24 is rotatably connected to the lower end of the support frame 31 via a rotating shaft. A third control motor 25 is fixedly mounted through the outer side of the upper end of the support frame 31. The drive shaft of the third control motor 25 is... A first swing gear 26 is fixedly installed, and a second swing gear 27 is meshed with the lower end of the first swing gear 26. The second swing gear 27 is fixedly installed on the outer curved surface of the side end of the swing shaft 24. An installation head 28 is fixedly installed on the outer curved surface of the middle part of the swing shaft 24. A spray gun 30 is fixedly installed on the outside of the installation head 28. The spray gun 30 is connected to the storage tank 3 through a connecting hose, so that the repair paint is extracted from the storage tank 3 by a high-pressure pump and delivered to the spray gun 30 under high pressure through the connecting hose. An observation camera 29 is fixedly installed on the upper end of the installation head 28 and is adapted to a remote monitor.

[0025] Working Principle: In use, this utility model uses a remote monitor in conjunction with an observation camera 29 to remotely observe the area of ​​the aircraft coating that needs repair. When the aircraft coating needs repair, the high-pressure pump is activated to extract the repair paint from the storage tank 3 and deliver it to the spray gun 30 under high pressure through a connecting hose. When the repair paint is delivered to the spray gun 30, the aircraft coating can be sprayed and repaired. During the spraying and repair of the aircraft coating, the moving gantry 1 is activated to move longitudinally in a straight line. When the moving gantry 1 moves longitudinally in a straight line, it will synchronously drive the spray gun 30. 0. The longitudinal linear movement adjustment is achieved by controlling the start of the adjustment motor 7. When the adjustment motor 7 is started, it drives the first synchronous pulley 8 to rotate. When the first synchronous pulley 8 rotates, it works in conjunction with the second synchronous pulley 10 to drive the adjustment synchronous belt 9 to rotate and transport. When the adjustment synchronous belt 9 rotates and transports, it drives the transverse moving table 6 and the limit slide 5 to move laterally and linearly along the upper end of the transverse linear slide rail 4. When the transverse moving table 6 moves laterally and linearly, it synchronously drives the spray gun 30 to move laterally and linearly. This allows for spraying and repairing the aircraft coating while facilitating longitudinal and transverse linear movement adjustment of the spraying position.

[0026] Simultaneously, by controlling the activation of the first control motor 17, the first lifting gear 18 rotates, which in turn meshes with and drives the second lifting gear 19 to rotate. The second lifting gear 19 then rotates, causing the internal threaded transmission tube 12 to rotate. This rotation, due to the force generated by the threaded connection, causes the lifting screw 15 to move up and down. This up-and-down movement of the lifting screw 15 causes the lifting platform 16 to move linearly up and down, which in turn synchronously drives the spray gun 30 to move linearly up and down. By controlling the activation of the second control motor 20, when the second control motor 20 is activated... The system sequentially drives the first rotating gear 21, the second rotating gear 22, the rotating platform 23, and the support frame 31 to rotate horizontally. When the rotating platform 23 rotates horizontally, it synchronously drives the spray gun 30 to rotate horizontally. By controlling the activation of the third control motor 25, the system sequentially drives the first swing gear 26, the second swing gear 27, the swing shaft 24, and the mounting head 28 to swing up and down. When the mounting head 28 swings up and down, it synchronously drives the spray gun 30 and the observation camera 29 to swing up and down. This allows for the spraying and repair of the aircraft coating while facilitating vertical linear movement, horizontal rotation, and vertical swing adjustment of the spraying position, enabling rapid positioning and repair of the aircraft coating.
