Description

Technical Field

[0001] This utility model relates to the technical field of landing gear installation devices, and in particular to an auxiliary tool for aircraft landing gear installation. Background Technology

[0002] As is generally known, landing gear is the main load-bearing component of an aircraft when it is parked, taxiing, taking off, or landing. When the landing gear is fully extended or retracted and the cabin door is closed, an installation vehicle is generally required to move and transport the aircraft landing gear during installation.

[0003] The Chinese patent CN211731856U describes an aircraft main landing gear mounting vehicle. This device includes a mounting vehicle body and wheels. Two pairs of wheels are connected to the lower part of the mounting vehicle body. A frame and a first housing are fixed to the upper center and left side of the mounting vehicle body, respectively. A first screw is rotatably connected inside the first housing via a pair of bearings. An adjustment mechanism is installed on the lower outer wall of the first screw. A first adjusting arm is threadedly connected to the upper outer wall of the first screw. A second adjusting arm is rotatably connected to the groove of the first adjusting arm via a rotating shaft. A fixing mechanism is installed inside the second adjusting arm. However, the following problems exist in actual use:

[0004] Aircraft landing gear is typically installed directly onto the aircraft as a landing gear assembly. During installation, the landing gear needs to be aligned with the aircraft mounting ports on both sides of the landing gear. If slight misalignment occurs during the alignment process, the landing gear needs to be tilted to achieve alignment. Alternatively, if there is a slight misalignment where the aircraft mounting ports on both sides of the landing gear are not on the same horizontal plane, installers usually try to align the landing gear by forcibly prying it or by tapping it with a rubber mallet. In this case, the clamping device may damage the clamping parts of the landing gear, or the prying or tapping may damage the parts of the landing gear that are being pried or tapped.

[0005] Therefore, an auxiliary tool for aircraft landing gear installation is proposed. Utility Model Content

The two sets of rotating wheels 12 are rotatably connected to the clamping block 6. The side of the clamping block 6 near the object being clamped has a horizontal groove.

The tilt adjustment bracket 13 is connected to the lifting end of the lifting component 2.

[0034] like Figure 2-5As shown, the tilt adjustment assembly includes a hydraulic support rod 14, a hydraulic push rod 15, a universal ball 16, a slider 17, and a hydraulic pump 18. The bottom end of the hydraulic support rod 14 is fixedly connected to the upper surface of the tilt adjustment bracket 13, and the hydraulic support rod 14 is located on the upper surface of the tilt adjustment bracket 13 near the lifting component 2. The top end of the hydraulic support rod 14 is fixedly connected to the universal ball 16. The lower surface of the clamping bracket 3 is provided with a hemispherical groove, and the universal ball 16 is located in the hemispherical groove of the clamping bracket 3 and is slidably connected to the clamping bracket 3.

The hydraulic push rod 15 is located in the sliding groove of the tilt adjustment bracket 13. The hydraulic support rod 14 and the hydraulic push rod 15 are respectively connected to the hydraulic pump 18 through hydraulic pipes.

[0035] like Figure 8 As shown, the slider 17 includes a slider base 19, a slider support rod 20, and a spring 21. The slider base 19 has a groove, and the slider support rod 20 is located in the groove of the slider base 19 and is slidably connected to the slider base 19. The slider base 19 and the slider support rod 20 are connected by the spring 21. The bottom end of the slider base 19 is slidably connected to the tilt adjustment bracket 13, and the top end of the slider support rod 20 is rotatably connected to the clamping bracket 3.

[0036] The work process is as follows:

[0037] S1. In use, place the landing gear in the corresponding position on the device, start the servo motor 9, which drives the bidirectional threaded rod 7 to rotate via the coupling 8. The threads at the front and rear of the bidirectional threaded rod 7 rotate in opposite directions, causing the two push plates 5 to slide towards each other. The two push plates 5 push the two clamping blocks 6 to slide towards each other, thus clamping the landing gear. Then, move the landing gear below the desired installation position on the aircraft via the movable base 1. Start the lifting component 2, which pushes the clamping bracket 3 via the lifting tilt adjustment bracket 13, lifting the clamped landing gear to the required installation position. When installing the landing gear on the aircraft, align the mounting openings on both sides. When the two mounting ports on the aircraft are in a horizontal position but the landing gear needs to be tilted to align with the mounting ports, the hydraulic pump 18 is activated. The hydraulic support rod 14 lifts the clamping bracket 3 to the side near the lifting component 2. At the same time, the hydraulic push rod 15 retracts synchronously, pulling the slider 17 towards the lifting component 2, so that the clamping bracket 3 forms an inclined surface. This causes the landing gear to tilt and align with the aircraft's mounting ports for installation. This avoids damage to the landing gear clamping parts caused by manual prying or knocking when the landing gear needs to be tilted to align with the mounting ports. It also avoids damage to the knocking or prying parts caused by prying or knocking the landing gear, thus improving installation efficiency.

[0038] S2, when the two mounting ports on the aircraft are in a horizontal position but the landing gear needs to be rotated to align with the mounting ports, the landing gear can be rotated manually. The landing gear is held by two sets of rotating wheels 12 horizontally set on the two clamping blocks 6. It is already clamped in the vertical direction. The rotating wheels 12 are rotatably connected, so the manual can easily rotate it. This avoids the waste of manpower caused by having to rotate the entire device when the landing gear needs to be rotated to align with the mounting ports, thereby improving efficiency.

[0039] S3. When the two mounting ports on the aircraft are misaligned with the landing gear positions, first start the hydraulic pump 18 to tilt the landing gear. Then adjust the landing gear position so that the center of the landing gear is at the center of the misaligned mounting ports. Then manually rotate the landing gear to align the mounting ports. This avoids damage to the clamping parts of the landing gear when the two mounting ports on the aircraft are misaligned and the landing gear is forcibly pried or knocked. It also avoids damage to the pried or knocked parts when the landing gear is pried or knocked, thus improving installation efficiency.

[0040] The landing gear tilt angle is adjusted by using a hydraulic support rod 14 and a hydraulic push rod 15. To reduce the impact force when adjusting the landing gear tilt angle, the oil inside the hydraulic rod itself is a good buffer medium. The clamping block 6 adopts a structure with a clamping inclined block 10 and a clamping flat block 11. When clamping the aircraft landing gear, it forms a "V" shape, which can provide better support for the landing gear. The slider 17 adopts a structure with a slider base 19, a slider support rod 20 and a spring 21. It can provide a certain degree of self-adaptation during the adjustment of the landing gear tilt angle, and also play a buffering role.

[0041] The parts of this utility model not described in detail are prior art. Although this utility model has been specifically shown and introduced in conjunction with preferred embodiments, there are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. However, those skilled in the art should understand that various changes in form and detail can be made to this utility model without departing from the spirit and scope of this utility model as defined by the appended claims, and all such changes shall be within the protection scope of this utility model.
