Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of aircraft maintenance equipment, in particular to an undercarriage frame carrying carrier and an aircraft accessory conveying device. BACKGROUND

[0002] An aircraft undercarriage such as disclosed in Chinese patent document CN212605777U usually supports an aircraft through a triangular undercarriage frame, which often causes the undercarriage frame to be damaged during pressure bearing, and thus the frame needs to be frequently replaced. In order to improve the replacement efficiency, most manufacturers will use a multifunctional aircraft main undercarriage storage vehicle such as disclosed in Chinese patent document CN214451204U to carry the new parts for replacing the aircraft undercarriage. Since the undercarriage frame is plate-shaped and heavy, in order to prevent the frame for replacement from falling during carrying, the frame for replacement is usually placed flat on the vehicle body and kept close to the flat plate of the vehicle body to reduce the center of gravity. However, when the frame for replacement is installed on the aircraft, the frame for replacement needs to be lifted. After the frame for replacement is attached to the flat plate of the vehicle body under its own weight, it is inconvenient for a person to exert force to lift the frame for replacement, thereby affecting the installation efficiency of the undercarriage frame.

The terminology used in the description of the present disclosure herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0034] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in combination with specific embodiments:

[0035] Please refer to Figure 1The landing gear frame carrying device in one embodiment comprises a carrying plate 100, a cushion plate 200 and a triangular lifting frame 300. The carrying plate 100 is used for loading on a forklift. The cushion plate 200 is fixedly installed on the carrying plate 100. The triangular lifting frame 300 is arranged above the cushion plate 200, and the triangular lifting frame 300 is used for placing the landing gear frame. Each corner 310 of the triangular lifting frame 300 is attached to the surface of the cushion plate 200 and detachably connected with the cushion plate 200. At least one side 320 of the triangular lifting frame 300 is located outside the cushion plate 200 and horizontally placed above the carrying plate 100. The at least one side 320 of the triangular lifting frame 300 and the carrying plate 100 form a placing space 301, which is used for placing a clamping tool when lifting the landing gear frame. The clamping tool can be a jaw connected with a crane, which is not limited in particular.

[0036] It can be understood that, since each corner 310 of the triangular lifting frame 300 is attached to the surface of the cushion plate 200 and detachably connected with the lifting frame, each corner 310 of the triangular lifting frame 300 is stably supported by the lifting frame to support the landing gear frame. Since at least one side 320 of the triangular lifting frame 300 is located outside the cushion plate 200 and horizontally placed above the carrying plate 100, when the landing gear frame needs to be lifted, the clamping tool can be placed in the placing space 301 formed between the at least one side 320 of the triangular lifting frame 300 and the carrying plate 100 to firmly clamp the side 320 of the triangular lifting frame 300. After the connection between the cushion plate 200 and the lifting frame is released, the triangular lifting frame 300 together with the landing gear frame can be lifted by the clamping tool, so that the frame for replacement can be quickly lifted and installed on the airplane. In this way, the landing gear frame carrying device can not only reduce the amount of manual labor, but also adapt to the clamping of the clamping tool to improve the installation efficiency of the landing gear frame. The cushion plate 200 is welded on the carrying plate 100.

[0037] Please refer to Figure 1 In some embodiments, two adjacent sides 320 of the triangular lifting frame 300 are located outside the cushion plate 200 and horizontally placed on the carrying plate 100. The two adjacent sides 320 and the corresponding positions of the carrying plate 100 form a placing space 301. It can be understood that, since the two adjacent sides 320 of the triangular lifting frame 300 are located outside the cushion plate 200 and form a placing space 301 between the two adjacent sides 320 and the corresponding positions of the carrying plate 100, one clamping tool can be placed in each placing space 301. By synchronously applying force to the triangular lifting frame 300 by each clamping tool, the triangular lifting frame 300 can be stably lifted, and the landing gear frame on the triangular lifting frame 300 can be stably lifted.

[0038] Please refer toFigure 1 In some embodiments, the triangular lifting frame 300 is arranged in an equilateral triangle. It can be understood that, since the triangular lifting frame 300 is arranged in an equilateral triangle, the center of gravity of the triangular lifting frame 300 coincides with the geometric center of the triangular lifting frame 300, thereby improving the stability of the triangular lifting frame 300 after being lifted.

[0039] Referring to Figure 1 With Figure 2 In some embodiments, the landing gear frame body also includes a limiting buckle 400; the limiting buckle 400 is fixedly installed on the pad plate 200 and arranged close to the corner position 310 of the triangular lifting frame 300; the limiting buckle 400 is formed with a limiting buckle opening 401, which is adapted to the outer contour of the corner position 310 of the triangular lifting frame 300. It can be understood that, by forming the limiting buckle opening 401 on the limiting buckle 400 fixedly installed on the pad plate 200 to be adapted to the outer contour of the corner position 310 of the triangular lifting frame 300, the triangular lifting frame 300 can be stably limited on the pad plate 200, thereby reducing the displacement of the triangular lifting frame 300 during the forklift transportation of the landing gear frame body.

[0040] Referring to Figure 1 With Figure 2 In some embodiments, the number of limiting buckles 400 is at least two, and the limiting buckle opening 401 of each limiting buckle 400 is adapted to the outer contour of one corner position 310 of the triangular lifting frame 300. It can be understood that, by adapting the limiting buckle opening 401 of each limiting buckle 400 to the outer contour of one corner position 310 of the triangular lifting frame 300, each corner position 310 of the triangular lifting frame 300 can be limited, thereby further reducing the displacement of the triangular lifting frame 300 during the forklift transportation of the landing gear frame body.

[0041] Referring to Figure 1 With Figure 2In some embodiments, the landing gear frame carrier further comprises a supporting and pushing assembly 500; the supporting and pushing assembly 500 is installed on the pad plate 200 and located between two adjacent limiting buckles 400; the triangular lifting frame 300 is in sliding contact with the surface of the pad plate 200, and the supporting and pushing assembly 500 is in contact with the edge of the side edge 320 of the triangular lifting frame 300 away from the limiting buckle 400. It can be understood that, since the triangular lifting frame 300 is in sliding contact with the surface of the pad plate 200, the supporting and pushing assembly 500 located between two adjacent limiting buckles 400 is in contact with the edge of the side edge 320 of the triangular lifting frame 300 away from the limiting buckle 400. By adjusting the supporting and pushing assembly 500, the supporting and pushing assembly 500 pushes the triangular lifting frame 300 to be close to the two limiting buckles 400, so as to fix the triangular lifting frame 300 by the supporting and pushing assembly 500 and the limiting buckles 401 of the two adjacent limiting buckles 400, and finally make each corner position 310 of the triangular lifting frame 300 be detachably connected to the pad plate 200.

[0042] Please refer to Figure 2 and Figure 3 In some embodiments, the supporting and pushing assembly 500 comprises a supporting block 510 and two pushing blocks 520; the two pushing blocks 520 are both slidingly arranged on the pad plate 200, and the supporting block 510 is arranged between the two pushing blocks 520 and is slidingly connected to the pushing blocks 520, so that the supporting block 510 pushes at least one pushing block 520 to be close to or away from the triangular lifting frame 300 when the supporting block 510 is raised or lowered. It can be understood that, since the supporting block 510 is arranged between the two pushing blocks 520 and is slidingly connected to the pushing blocks 520, and the two pushing blocks 520 are both slidingly arranged on the pad plate 200, in this embodiment, the cross-sectional area of the supporting block 510 gradually decreases from the end away from the pad plate 200 to the end close to the pad plate 200. When it is necessary to fix the triangular lifting frame 300, the supporting block 510 is moved downward between the two pushing blocks 520, and the supporting block 510 can push each pushing block 520 to slide on the pad plate 200, that is, the two pushing blocks 520 are relatively far away from each other, so that at least one pushing block 520 is close to and in contact with the triangular lifting frame 300. When it is necessary to release the fixation of the triangular lifting frame 300, the supporting block 510 is moved upward between the two pushing blocks 520, and the supporting block 510 can pull each pushing block 520 to slide on the pad plate 200, that is, the two pushing blocks 520 are relatively close to each other, so that at least one pushing block 520 is away from the triangular lifting frame 300. At this time, the triangular lifting frame 300 can be moved between the supporting and pushing assembly 500 and the two adjacent limiting buckles 400, and the triangular lifting frame 300 can be detached from the pad plate 200.

[0043] Please refer to Figure 3 and Figure 4In some embodiments, an inclined guide groove 5201 is formed on the pushing block 520, and a clamping structure 5110 is arranged on the supporting block 510; the clamping structure 5110 is clamped and matched with the inclined guide groove 5201, and is slidably abutted against the groove wall of the inclined guide groove 5201. It can be understood that, by clamping and matching the clamping structure 5110 on the supporting block 510 with the inclined guide groove 5201 and slidably abutting against the groove wall of the inclined guide groove 5201, the connection between the supporting block 510 and the two pushing blocks 520 can be maintained at all times when the pushing block 520 slides along the inclined guide groove 5201, so as to synchronously push and pull the two pushing blocks 520 away from or close to each other. Please refer to Figure 4 In some embodiments, the clamping structure 5110 is in the shape of an I-shaped structure, and the clamping direction of the clamping structure 5110 and the guiding direction of the inclined guide groove 5201 are located in the same plane, that is, the clamping structure 5110 does not interfere with the movement of the pushing block 520.

[0044] Please refer to Figure 3 In some embodiments, the supporting and pushing assembly 500 further comprises an adjusting screw and a compression spring 540, and a lifting sliding hole 5101 is formed on the supporting block 510; the compression spring 540 is arranged between the supporting block 510 and the cushion plate 200, the screw head body 5310 of the adjusting screw is abutted against the supporting block 510, the screw rod body 5320 of the adjusting screw is slidably arranged through the lifting sliding hole 5101 and the central hole of the compression spring 540, and is threadedly matched in the screw hole 201 of the cushion plate 200. It can be understood that, since the screw rod body 5320 of the adjusting screw is slidably arranged through the lifting sliding hole 5101 and the central hole of the compression spring 540, and is threadedly matched in the screw hole 201 of the cushion plate 200, when the adjusting screw is screwed downward, the adjusting screw is abutted against the supporting block 510 to push the supporting block 510 to overcome the elastic force of the compression spring 540 and descend, and when the adjusting screw is screwed upward, the compression spring 540 pushes the supporting block 510 to ascend by overcoming the gravity of the supporting block 510, so that the supporting block 510 can be flexibly driven to ascend and descend by screwing the adjusting screw.

[0045] Please refer to Figure 1 The present disclosure also provides an aircraft accessory conveying device, which comprises a forklift and the landing gear frame carrying carrier of any of the above embodiments, and the carrying board 100 is loaded on the forklift. It can be understood that, by loading the carrying board 100 on the forklift, the forklift can be used to convey the carrying board 100, and the landing gear frame carrying carrier can be flexibly carried to different positions, which is more convenient to use.

[0046] Compared with the prior art, the present disclosure has at least the following advantages:

[0047] The landing gear frame carrier described above, since the corners 310 of the triangular lifting frame 300 are attached to the surface of the cushioning plate 200 and detachably connected with the lifting frame, the corners 310 of the triangular lifting frame 300 are stably supported by the lifting frame, and at least one side 320 of the triangular lifting frame 300 is located outside the cushioning plate 200 and horizontally placed above the carrier plate 100. When the landing gear frame needs to be lifted, a space 301 can be formed by placing a clamping tool between at least one side 320 of the triangular lifting frame 300 and the carrier plate 100, so as to firmly clamp the side 320 of the triangular lifting frame 300. After the connection between the cushioning plate 200 and the lifting frame is released, the triangular lifting frame 300 can be lifted together with the landing gear frame by the clamping tool, so that the replacement frame can be quickly lifted and installed on the aircraft. In this way, the landing gear frame carrier described above not only reduces the amount of manual labor, but also adapts to the clamping of the clamping tool, thereby improving the installation efficiency of the landing gear frame.

[0048] The above-described embodiments only express several embodiments of the present disclosure, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present disclosure, several modifications and improvements can be made, which are within the scope of the present disclosure. Therefore, the protection scope of the present disclosure patent should be subject to the appended claims.
