[0001] This utility model relates to the field of engine inspection technology, and in particular to a device for quickly disassembling an adapter on an aircraft. Background Technology

[0002] When inspecting the clutch gears in a turboshaft engine field, the air starter adapter needs to be disassembled. During this disassembly, due to the specific fit requirements between the rotating component and the adapter, the rotating component is often removed along with the adapter. An adjusting shim is attached to the bottom of the rotating component. As the component is removed with the adapter, this shim is highly susceptible to falling off and into the accessory drive housing. If not detected and removed promptly, this can pose a quality hazard during engine operation. Currently, removing the adapter requires one person to disassemble the adapter while another person secures the rotating component to prevent it from falling off during disassembly. This method is time-consuming, labor-intensive, and inefficient. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figures 1-3 As shown, a rotating component B is provided in the middle of the adapter A, and the adapter A passes through the top of the rotating component B. A device for quickly disassembling the adapter on an aircraft includes a crossbeam 3, an adjustment assembly 1, and several lifting claws 2. The adjustment assembly 1 includes an adjustment rod 12, a lever 11, and a pressure head 13. The adjustment rod 12 is movably and heightily disposed in the middle of the crossbeam 3. A threaded hole is provided in the middle of the crossbeam 3. The adjustment rod 12 and the threaded hole are connected by threads. The lever 11 is disposed on the adjustment rod 12. The lever 11 and the adjustment rod 12 are perpendicular to each other. When the lever 11 is rotated, the adjustment rod 12 can rotate and move within the threaded hole. The lever 11 increases the distance between the force application position and the rotation position, making the rotation of the adjustment rod 12 easier and facilitating the adjustment of the position of the adjustment rod 12 on the crossbeam 3.

[0028] like Figures 1-4As shown, the lifting claw 2 is mounted on the crossbeam 3 and slidably mounted on both sides of the adjusting rod 12. A groove 21 is provided at the upper end of the lifting claw 2, and the crossbeam 3 is connected within the groove 21. The dimensions of the crossbeam 3 and the groove 21 are the same, allowing the lifting claw 2 to slide only along the direction of the crossbeam 3 and preventing it from rotating on the crossbeam 3. Several sliding grooves 31 are provided on the crossbeam 3, penetrating the crossbeam 3. The sliding grooves 31 are respectively located on both sides of the threaded hole. A connecting hole 23 is provided on the lifting claw 2, aligned with the sliding groove 31. A bolt 4 is provided on the lifting claw 2, positioned at the location of the connecting hole 23, and threadedly connected to the connecting hole 23. The bolt 4 is located within the sliding groove 31, with a nut supporting the upper end of the sliding groove 31. The bolt 4 acts as a connector, linking the crossbeam 3 and the lifting claw 2. The claw 2 acts as a limit, allowing the lifting claw 2 to slide only along the slide groove 31. The interior of the lifting claw 2 is hollow, and the lower end of the lifting claw 2 is arc-shaped. The lower end of the lifting claw 2 is provided with a bent section 22. The two lifting claws 2 can approach each other and abut against the adapter A. The bent section 22 is connected to the lower end of the adapter A. When the lifting claw 2 abuts against the adapter A, the bolt 4 is rotated, which shortens the distance between the lifting claw 2 and the crossbeam 3. This increases the connection stability between the lifting claw 2 and the crossbeam 3, making the lifting claw 2 stable and preventing it from wobbling at the lower end of the bolt 4. The bent section 22 hooks onto the lower end of the adapter A, allowing the adapter A to be lifted stably. Several grooves are penetrated on the outer wall of the lifting claw 2, allowing the contact between the lifting claw 2 and the adapter A to be observed from the outside when the lifting claw 2 is moving, thus maximizing the connection strength between the two.

[0029] like Figures 1-3 As shown, the lower end of the adjusting component 1 abuts against the rotating component B. The pressure head 13 is rotatably disposed at the lower end of the adjusting rod 12. The pressure head 13 is provided with a through groove 132 and a rotating groove 131. The rotating groove 131 is disposed inside the pressure head 13. The through groove 132 passes through one end of the pressure head 13 and communicates with the rotating groove 131. The diameter of the rotating groove 131 is larger than the diameter of the through groove 132. The adjusting rod 12 is provided with a groove 121. The end of the adjusting rod 12 is disposed in the rotating groove 131. The groove 121 is connected to the position of the through groove 132. Due to the variable diameter of the rotating groove 131 and the through groove 132, after the pressure head 13 and the adjusting rod 12 are connected, the adjusting rod 12 can rotate inside the pressure head 13, and the pressure head 13 will not detach from the lower end of the adjusting rod 12.

[0030] like Figures 1-3As shown, in the air starter, the rotating part B is a rotating shaft, and the lower end of the pressure head 13 is provided with an abutment groove 133. The abutment groove 133 is concave on the pressure head 13. The upper end of the rotating part B and the abutment groove 133 are abutted together. After the abutment groove 133 is provided, the adjusting rod 12 gradually moves towards the rotating shaft, so that the abutment groove 133 and the rotating shaft abut together. This allows the rotating shaft to stop rotating while keeping the adjusting pad C and the rotating shaft stable during the removal of the adapter A, preventing the adjusting pad C from falling off during the removal of the adapter A.

[0031] Disassembly principle: First, rotate the adjusting rod 12 so that the pressure head 13 and the rotating part B abut. Place the lifting claw 2 on the outside of the adapter A. Adjust the position of the lifting claw 2 so that the inner wall of the lifting claw 2 abuts against the adapter A. The bent section 22 is connected to the lower end of the adapter A. Rotate the bolt 4 to shorten the distance between the lifting claw 2 and the crossbeam 3 and keep it stable. At this time, continue to rotate the adjusting rod 12 so that the abutting groove 133 of the pressure head 13 continues to abut against the rotating part B. The adjusting rod 12 moves continuously towards the rotating part B. The adapter A is lifted up by the lifting claw 2. Only one person is needed to operate the lifting process. The whole lifting process is stable and efficient, avoiding the removal of the rotating part B along with the disassembly of the adapter A, which would cause the adjusting pad C to fall off.

[0032] Example 2

[0033] like Figures 4-7 As shown, the structure of the pressure head 13 is adjusted based on Embodiment 1. Specifically, a protrusion 134 is provided at the lower end of the pressure head 13, protruding outward on the pressure head 13. The upper end of the rotating part B abuts against the protrusion 134. The aircraft fuel pump has a similar adapter A, but the rotating part B inside the fuel pump is a gear. After the protrusion 134 is provided, the adjusting rod 12 gradually moves towards the gear, causing the protrusion 134 to abut against the gear. This stops the gear from rotating and ensures that the adjusting pad C and the gear remain stable during the removal of the adapter A, preventing the adjusting pad C from falling off. The aircraft fuel regulator has a mounting base D. The removal method of the mounting base D is the same as that of the adapter A. The rotating part B in the middle of the mounting base D is concave. When removing the mounting base D, a device with a protrusion 134 is used, allowing the protrusion 134 to extend into the rotating part B, increasing the connection strength between the device and the mounting base D and preventing the device from shaking.

[0034] This is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
