[0035] To make the purpose, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other in any way.

[0036] Aircraft engines typically consist of multiple critical components, including the compressor, combustion chamber, and turbine. During transportation, maintenance, and installation, the engine needs to be removed from or installed on the aircraft. This process requires a safe and reliable support device to protect the engine from damage and ensure the safety of the personnel.

[0037] When disassembling and assembling an aircraft engine, the existing disassembly and assembly support device cannot be adjusted according to the size and position of the aircraft engine, which brings inconvenience to the disassembly and assembly of the aircraft engine.

[0038] Please combine Figure 1 、 Figure 2 and Figure 4The present disclosure provides a disassembly and assembly support device that can support an aircraft engine during its disassembly and assembly. The disassembly and assembly support device includes a support platform assembly 10, a clamping mechanism 20, and a support mechanism 30.

[0039] The support platform assembly 10 includes a main support platform 11 and at least one auxiliary support platform 12. The auxiliary support platform 12 is slidably connected to the main support platform 11 and is capable of moving circumferentially outward from the main support platform 11 along a first direction. In the disclosed embodiment, there are two auxiliary support platforms 12, which are arranged on either side of the main support platform 11 along the first direction. Depending on the axial size of the aircraft engine, the auxiliary support platform 12 on one side can be moved circumferentially outward from the main support platform 11, or both auxiliary support platforms 12 on both sides can be moved circumferentially outward from the main support platform 11 simultaneously, thereby increasing the size of the support platform assembly 10.

[0040] The clamping mechanism 20 is disposed on the support surface 111 of the main support platform 11. The clamping mechanism 20 is provided with a clamping space 100. The clamping mechanism 20 is configured to adjust the size of the clamping space 100 along a second direction, wherein the first direction is the axial direction of the aircraft engine, and the second direction is the radial direction of the aircraft engine. By increasing the size of the clamping space 100, the clamping mechanism 20 can facilitate the placement of the aircraft engine into the clamping space 100. By reducing the size of the clamping space 100, the clamping mechanism 20 can clamp the aircraft engine to the support platform assembly 10.

[0041] The support mechanism 30 is provided on the main support platform 11, and the support mechanism 30 is provided to be able to adjust the position of the support platform assembly 10 along a third direction, wherein the third direction is perpendicular to the plane where the first direction and the second direction are located. Figure 1 The second direction is parallel to the direction indicated by the arrow X. Figure 1 The direction indicated by the arrow Y. The third direction is parallel to Figure 1 The arrow Z in the middle points to the direction.

[0042] The embodiment of the present disclosure includes a support platform assembly 10, a clamping mechanism 20 and a support mechanism 30. The support platform assembly 10 includes a main support platform 11 and at least one auxiliary support platform 12. The auxiliary support platform 12 can move along the first direction toward the circumferential outside of the main support platform 11, so that the size of the support platform assembly 10 along the first direction can be increased, so that the area of ​​the support platform assembly 10 is larger, which is convenient for placing aircraft engines with larger axial dimensions on the support platform assembly 10, increasing the support area for the aircraft engine, avoiding accidental falling off or sliding of the aircraft engine due to a small support area, and improving the safety of disassembly and assembly. The clamping mechanism 20 can adjust the size of the clamping space 100 along the second direction, so as to facilitate the clamping of aircraft engines of different radial sizes. The support mechanism 30 is configured to be able to adjust the position of the support platform assembly 10 along the third direction, so that the height of the support platform assembly 10 can be adjusted according to the needs of the disassembly and assembly personnel, facilitating the disassembly and assembly of the aircraft engine, and improving safety and work efficiency.

[0043] In an exemplary embodiment, please refer to Figure 1 、 Figure 2 and Figure 4 , the main support platform 11 is provided with a receiving space 200 away from the supporting surface 111. The receiving space 200 is provided with a first driving unit 40 connected between the main support platform 11 and the auxiliary support platform 12. The first driving unit 40 is configured to drive the auxiliary support platform 12 to move along the first direction toward the circumferential outside of the main support platform 11 or to be received in the receiving space 200. In this way, the auxiliary support platform 12 can be conveniently driven by the first driving unit 40. The first driving unit 40 can be an electrically controlled driving unit or a manually driven driving unit. The provision of the receiving space 200 can accommodate the auxiliary support platform 12, facilitate the transportation of the disassembly and assembly of the support device, and facilitate the installation of the first driving unit 40, as well as facilitate the first driving unit 40 to connect the main support platform 11 and the auxiliary support platform 12. In the embodiment of the present disclosure, the main support platform 11 includes a supporting surface 111 and a body 112. The receiving space 200 is provided in the body 112, and the supporting surface 111 can be connected to the body 112 to cover the receiving space 200. The support surface 111 can be detachably connected to the body 112 to facilitate installation of the first driving unit 40 .

[0044] In an exemplary embodiment, as Figure 2 As shown, the first drive unit 40 is an electric push rod. It can be understood that in other embodiments, the first drive unit 40 can also be a cylinder, a hydraulic cylinder or an electric screw.

[0045] The receiving space 200 is also provided with a damping telescopic rod 50 connected between the main support platform 11 and the auxiliary support platform 12. The damping telescopic rod 50 is configured to change the amount of extension and contraction of the damping telescopic rod 50 along the first direction as the auxiliary support platform 12 moves along the first direction. The damping telescopic rod 50 can provide a certain damping effect and guiding function, ensuring that the auxiliary support platform 12 can move relatively stably along the first direction under the drive of the first drive unit 40, and preventing the auxiliary support platform 12 from shaking during movement. In addition, the provision of the damping telescopic rod 50 can also provide support for the auxiliary support platform 12.

[0046] The first drive unit 40 and the damping telescopic rod 50 are spaced apart along the second direction. In the embodiment of the present disclosure, there are two damping telescopic rods 50, which are arranged on both sides of the first drive unit 40 along the second direction, further improving the stability of the movement of the auxiliary support platform 12.

[0047] In the exemplary embodiment, please combine Figure 1 、 Figure 2 and Figure 4 The support mechanism 30 includes multiple support components 31 and drive components 32. The multiple support components 31 are evenly distributed around the side of the main support platform 11 away from the support surface 111, which can improve the stability of the support of the support platform component 10.

[0048] The support assembly 31 includes a first support rod 311 and a second support rod 312, and the second support rod 312 is arranged on the main support platform 11 and is slidably connected to the first support rod 311. The driving assembly 32 is connected to the second support rod 312, and can drive the second support rod 312 to slide relative to the first support rod 311 along a third direction to adjust the position of the support platform assembly 10 along the third direction. The first support rod 311 can be set on the ground, and the position of the support platform assembly 10 can be adjusted by changing the position of the second support rod 312 relative to the first support rod 311. In order to improve the stability of the support assembly 31 supporting the support platform assembly 10, the end of the first support rod 311 connected to the ground has a larger area to increase the contact surface area with the ground. In addition, in some embodiments, a pulley assembly can also be provided at the end of the first support rod 311 connected to the ground to facilitate the transportation and disassembly of the support device.

[0049] The disclosed embodiment facilitates driving the second support rods 312 through the provision of a drive assembly 32. The drive assembly 32 can be either electrically controlled or manually driven. The drive assembly 32 can simultaneously drive multiple second support rods 312, ensuring that the support platform assembly 10 can be smoothly raised and lowered relative to the ground. The drive assembly 32 can also drive multiple second support rods 312 in steps, allowing the support platform assembly 10 to tilt relative to the ground.

[0050] In this disclosure, please combine Figure 3 and Figure 5 The driving assembly 32 includes a second driving unit, a worm 321 , a worm wheel 322 , a connecting rod 323 and a transmission rod 324 .

[0051] The output end of the second drive unit is connected to a worm 321, which meshes with a worm wheel 322. The worm wheel 322 is sleeved on a connecting rod 323 and coaxially arranged with the connecting rod 323, allowing the worm wheel 322 and the connecting rod 323 to rotate coaxially. A transmission rod 324 is radially arranged on the connecting rod 323, allowing the transmission rod 324 to swing around the connecting rod 323. The transmission rod 324 is slidably hinged to the second support rod 312, so that when the transmission rod 324 swings around the connecting rod 323, it can slide and rotate relative to the second support rod 312. This allows the second support rod 312 to move in a third direction relative to the first support rod 311 under the drive of the transmission rod 324. The transmission rod 324 can change its relative position and relative angle with the second support rod 312 in real time to prevent the transmission rod 324 from driving the second support rod 312 to become stuck. In the disclosed embodiment, the second support rod 312 has a hinge axis 3121. The transmission rod 324 has a slide groove 300. The hinge shaft 3121 can be accommodated in the slide groove 300. When the transmission rod 324 drives the second support rod 312, the hinge shaft 3121 can slide along the slide groove 300, and the transmission rod 324 can rotate around the hinge shaft 3121 to change the relative position and relative angle between the transmission rod 324 and the second support rod 312. The transmission rod 324 has an inner wall that encloses and forms the slide groove 300. When the transmission rod 324 drives the second support rod 312, the inner wall can abut against the hinge shaft 3121 to transmit the driving force from the transmission rod 324 to the second support rod 312, thereby driving the second support rod 312 to move relative to the first support rod 311 along the third direction.

[0052] The second drive unit is configured to drive the worm 321 to rotate, so as to drive the connecting rod 323 to rotate through the worm wheel 322, drive the transmission rod 324 to swing around the connecting rod 323, and then drive the second support rod 312 to slide relative to the first support rod 311 along the third direction. The second drive unit can be a rotary motor or other drive unit capable of driving the worm 321 to rotate. The setting of the worm wheel 322 and the worm 321 can provide a certain locking effect when the second drive unit is shut down, so as to assist the second drive unit to fix the relative position of the worm wheel 322 and the worm 321, thereby ensuring that the position of the support platform assembly 10 is fixed. In the embodiment of the present disclosure, the axial direction of the worm 321 is parallel to the vertical direction, and the axial direction of the worm wheel 322 is parallel to the horizontal direction.

[0053] In the exemplary embodiment, please combine Figures 1 to 4The disassembly and assembly support device also includes a fixing frame 60. The fixing frame 60 connects the multiple first support rods 311 into one body to improve the stability of the overall structure of the multiple first support rods 311, ensure the stability of the support for the support platform assembly 10, and ensure that the second support rods 312 can move relatively stably relative to the first support rods 311 along the third direction, thereby improving the stability of adjusting the position of the support platform assembly 10 along the third direction. The second drive unit is provided on the fixing frame 60. In order to improve the working stability of the second drive unit and avoid external interference, the fixing frame 60 is also provided with a shell 70 capable of accommodating the second drive unit.

[0054] The fixing frame 60 is provided with a plurality of limit blocks 80. The connecting rod 323 is disposed through the limit blocks 80 and is rotationally connected thereto. The limit blocks 80 are configured to limit radial movement of the connecting rod 323. The provision of the limit blocks 80 prevents radial movement of the connecting rod 323, thereby ensuring the precise fit between the worm gear 322 and the worm 321 provided on the connecting rod 323, as well as the precise fit between the transmission rod 324 provided on the connecting rod 323 and the second support rod 312, thereby ensuring that the driving force of the second drive unit can be stably transmitted to the second support rod 312. The plurality of limit blocks 80 can be spaced apart along the axial direction of the connecting rod 323 to further prevent radial movement of the connecting rod 323.

[0055] In an exemplary embodiment, as Figure 3 As shown, the first support rod 311 is sleeved onto the second support rod 312. This increases the connection surface area between the first support rod 311 and the second support rod 312, improving the stability of the second support rod 312 relative to the first support rod 311. The first support rod 311 is provided with a clearance space 400 for the transmission rod 324 to prevent the first support rod 311 from interfering with the transmission rod 324 driving the second support rod 312.

[0056] In an exemplary embodiment, as Figure 3 As shown, the connecting rod 323 is provided with a limit ring 325 to limit the movement range of the transmission rod 324 along the connecting rod 323. This can prevent the transmission rod 324 from falling off from the connecting rod 323.

[0057] In the exemplary embodiment, please combine Figures 1 to 4, the number of support assemblies 31 is four, the number of worm wheels 322 and connecting rods 323 are two, and each connecting rod 323 is provided with two transmission rods 324. In this way, the worm 321 can simultaneously drive the two worm wheels 322 to rotate, and then simultaneously drive the four transmission rods 324 through the two connecting rods 323 to respectively drive the four second support rods 312 to move relative to the first support rod 311 along the third direction, thereby ensuring the smooth movement of the support platform assembly 10. In the embodiment of the present disclosure, the worm 321 is symmetrically arranged between the four support assemblies 31, the two connecting rods 323 extend along the first direction and are arranged on both sides of the worm 321 along the second direction, and the transmission rods 324 are respectively provided at both ends of the connecting rod 323 along the first direction. The transmission rod 324 extends along the radial direction of the connecting rod 323 to be slidably hinged with the corresponding second support rod 312. At least four stoppers 80 are provided for each connecting rod 323. Two stoppers 80 are provided on either side of the worm gear 322 along the first direction to ensure the precise fit between the worm gear 322 and the worm 321. The other two stoppers 80 are provided respectively near the two transmission rods 324 to ensure the precise fit between the transmission rods 324 and the second support rod 312.

[0058] In the exemplary embodiment, please combine Figure 1 and Figure 4 The clamping mechanism 20 includes two opposing clamping assemblies 21, each comprising a third drive unit 211 and a clamp 212. The two clamps 212 are arranged opposite each other along the second direction and together form a clamping space 100. The side of the clamp 212 facing the clamping space 100 is aligned with the aircraft engine to enhance its clamping stability. An elastic layer may also be provided on the side of the clamp 212 facing the clamping space 100 to prevent damage to the aircraft engine during clamping.

[0059] A support plate 90 connected to the support surface 111 is provided on the side of the clamp 212 facing away from the clamping space 100. The third drive unit 211 is connected between the clamp 212 and the support plate 90 and is configured to drive the clamp 212 to move along the second direction. In this way, the provision of the support plate 90 can provide support for the third drive unit 211 along the second direction, so that the clamping force transmitted to the aircraft engine by the third drive unit 211 through the clamp 212 is more stable. The embodiment of the present disclosure can facilitate the driving of the clamp 212 through the third drive unit 211. The third drive unit 211 can be an electronically controlled drive unit or a manually driven drive unit. The third drive unit 211 can be an electric push rod or a cylinder, a hydraulic cylinder or an electric lead screw.
