Description

Technical Field

[0001] The utility model relates to the technical field of aircraft maintenance equipment, in particular to an aircraft landing gear installation auxiliary tool. Background Art

[0002] General aircraft refers to the general term for all aircraft engaged in civil aviation activities other than scheduled passenger and cargo public air transport aircraft. General aircraft are the largest in number and model among all aircraft types, including small aircraft, large turbine and propeller aircraft, etc. The landing gear is the accessory device at the bottom of the aircraft used to support the aircraft during takeoff and landing or ground taxiing and for ground movement. The landing gear is the only component that supports the entire aircraft, so it is an indispensable part of the aircraft. Without it, the aircraft cannot move on the ground. After the aircraft takes off, the landing gear can be retracted depending on the flight performance.

[0003] For example, Chinese patent document CN220263073U discloses a universal small airplane landing gear installation tool, including a base, both sides of the upper end of the base are installed with lifting components, and both sides of the upper end of the base are installed with support platforms through the lifting components. The utility model adopts the above structure, when it is necessary to disassemble and assemble the universal small airplane landing gear, the support platform is driven to move upward by the lifting component, and the bracket is driven to move horizontally by the adjustment component, so that the bracket plays the role of clamping the landing gear, and after the landing gear is disassembled, the support platform is driven downward by the lifting component to separate the landing gear from the small airplane, and when installing the landing gear, the landing gear is fixed between the brackets, and the base is moved to the desired position, and the support platform is driven upward by the lifting component to dock the landing gear with the small airplane, and then the landing gear can be installed, which not only makes the landing gear more convenient when disassembling and assembling, but also effectively avoids the landing gear from falling.

[0004] The existing technology has the following problems:

[0005] The prior art uses two motors to drive the bracket to clamp the aircraft landing gear when clamping the aircraft landing gear. This clamping method is prone to clamping force deviation, resulting in unstable clamping, which reduces the practicality of the device. At the same time, the prior art does not support the bottom end of the aircraft landing gear when clamping and installing the aircraft landing gear, resulting in the appearance of a clamping pulley when the aircraft landing gear is lifted upward to reach the installation position during installation, thereby causing a dangerous situation in which the aircraft landing gear falls off, reducing the practicality of the device.

[0025] By the cooperation between the lifting mechanism 2 and the clamping mechanism 3, the aircraft landing gear can be clamped and lifted to a certain height. When the aircraft landing gear is lifted, the supporting mechanism 4 supports the bottom of the aircraft landing gear, so that the aircraft landing gear is more stable when lifted upward.

[0026] like Figure 2 , Figure 3 As shown, the output end of the motor 21 is fixedly connected to a threaded rod 22, the bottom end of the threaded rod 22 is rotatably connected to the bottom end of the inner cavity of the fixed box 11, the top of the threaded rod 22 is threadedly connected to a slider 23, the outer wall of the slider 23 is slidably connected to the inner wall of the fixed box 11, and the left end of the slider 23 is fixedly connected to the right end of the mounting plate 24.

[0027] By starting the motor 21, the threaded rod 22 is driven to rotate, so that the slider 23 slides on the outer wall of the threaded rod 22, and the slider 23 drives the mounting plate 24 to move synchronously. At the same time, the mounting plate 24 drives the fixing box 31 to move synchronously. When the fixing box 31 moves to a suitable height, the motor 21 is turned off to adjust the height.

[0028] like Figure 2 , Figure 3 As shown, the front and rear parts of the right end of the mounting plate 24 are fixedly connected with guide blocks 25, the outer wall of the guide block 25 is slidably connected to the inner wall of the fixed box 11, and the outer shape of the guide block 25 is T-shaped.

[0029] When the mounting plate 24 moves, the guide block 25 is driven to slide synchronously on the inner wall of the fixed box 11 , and the guide block 25 limits and guides the mounting plate 24 , so that the mounting plate 24 slides more smoothly.

[0030] like Figure 2 , Figure 4As shown, the front and rear parts of the right end of the fixed box 31 are fixedly connected to the limit block 32, the outer wall of the limit block 32 is slidably connected to the inner wall of the fixed box 11, the front and rear parts of the left end of the fixed box 31 are fixedly connected to the fixed plate 311, the front end of the fixed box 31 is fixedly connected to the motor 2 33, the output end of the motor 2 33 is fixedly connected to the bidirectional threaded rod 34, and the rear end of the bidirectional threaded rod 34 is rotatably connected to the rear end of the inner cavity of the fixed box 31.

[0031] When the fixed box 31 moves up and down, the fixed box 31 drives the limit block 32 to slide synchronously on the inner wall of the fixed box 11. The limit block 32 limits and guides the fixed box 31, so that the fixed box 31 moves more smoothly. Then, by starting the second motor 33, the bidirectional threaded rod 34 is driven to rotate synchronously.

[0032] like Figure 2 , Figure 4 As shown, the front and rear parts of the outer wall of the bidirectional threaded rod 34 are both threadedly connected with a slider 2 35, the outer wall of the slider 2 35 is slidably connected to the inner wall of the fixed box 31, the left end of the slider 2 35 is fixedly connected to a connecting plate 36, the outer wall of the connecting plate 36 is fixedly connected to a guide rod 1 37, the outer wall of the guide rod 1 37 is slidably connected to the inner wall of the fixed plate 311, and one end of the connecting plate 36 is fixedly connected to a clamping block 38.

[0033] When the bidirectional threaded rod 34 rotates, the slider 2 35 slides on the outer wall of the bidirectional threaded rod 34, and the slider 2 35 drives the connecting plate 36 to move synchronously, so that the connecting plate 36 drives the guide rod 1 37 to move synchronously, and the guide rod 1 37 slides on the inner wall of the fixed plate 311, and the connecting plate 36 is guided by the guide rod 1 37, so that the connecting plate 36 is more stable when moving. At the same time, the connecting plate 36 drives the clamping block 38 to move synchronously, so that the clamping block 38 clamps the aircraft landing gear, thereby achieving a clamping effect.

[0034] like Figure 2 , Figure 4 As shown, the output end of the telescopic cylinder 41 is fixedly connected to a supporting plate 42, the inner wall of the supporting plate 42 is slidably connected to a guide rod 43, the bottom end of the guide rod 43 is fixedly connected to the top of the movable base 1, and the highest point of the guide rod 43 is on the same horizontal line as the lowest point of the fixed box 31 that can be moved downward.

[0035] By starting the telescopic cylinder 41, the telescopic cylinder 41 drives the supporting plate 42 to rise upward, so that the supporting plate 42 slides on the outer wall of the guide rod 43, and the guide rod 43 limits and guides the supporting plate 42, so that the supporting plate 42 is more stable when moving. In this way, the supporting plate 42 supports the bottom of the aircraft landing gear, reducing the downward gravity borne by the clamping mechanism 3, making the clamping more stable and achieving a supporting effect.

[0036] The working principle of the utility model is as follows: when in use, the aircraft landing gear is moved onto the mobile base 1, so that the wheels at the bottom of the aircraft landing gear are in contact with the top of the supporting plate 42, and then, according to the size of the aircraft landing gear, the motor 21 is started to drive the threaded rod 22 to rotate, so that the slider 23 slides on the outer wall of the threaded rod 22, and the slider 23 drives the mounting plate 24 to move synchronously, so that the mounting plate 24 drives the guide block 25 to slide synchronously on the inner wall of the fixed box 11, and the guide block 25 limits and guides the mounting plate 24, so that the mounting plate 24 slides more smoothly. At the same time, the mounting plate 24 drives the fixed box 31 to move synchronously, and the fixed box 31 drives the limit block 32 to slide synchronously on the inner wall of the fixed box 11, and the limit block 32 limits and guides the fixed box 31, so that the fixed box 31 moves more smoothly. When the fixed box 31 moves to a suitable height, the motor 1 21 is turned off to adjust the height, and then the motor 2 33 is started to drive the bidirectional threaded rod 34 to rotate synchronously, so that the slider 2 35 slides on the outer wall of the bidirectional threaded rod 34, and the slider 2 35 drives the connecting plate 36 to move synchronously, so that the connecting plate 36 drives The guide rod 37 moves synchronously, so that the guide rod 37 slides on the inner wall of the fixed plate 311, and the guide rod 37 guides the connecting plate 36, so that the connecting plate 36 is more stable when moving. At the same time, the connecting plate 36 drives the clamping block 38 to move synchronously, so that the clamping block 38 clamps the aircraft landing gear, and plays a clamping effect. When the clamping is stable, the motor 21 is restarted to make the clamping mechanism 3 drive the aircraft landing gear to move upward, and at the same time, the telescopic cylinder 41 is started, and the telescopic cylinder 41 drives the supporting plate 42 to rise upward, so that the supporting plate 42 is on the guide rod 37. The outer wall of the second rod 43 slides, and the guide rod 43 limits and guides the supporting plate 42, so that the supporting plate 42 is more stable when moving. The supporting plate 42 supports the bottom of the aircraft landing gear, reducing the downward gravity borne by the clamping mechanism 3, making the clamping more stable and achieving a supporting effect. Moreover, when the clamping mechanism 3 rises to the highest point, the inner wall of the supporting plate 42 will not separate from the outer wall of the guide rod 43. Then the aircraft landing gear can be moved to the height where it needs to be installed and installed, thereby greatly improving the user experience.
