Description

Technical Field

[0001] This invention relates to the technical field of landing gear disassembly devices, specifically to a landing gear disassembly device and disassembly method. Background Technology

[0002] The Cirrus SR20-G6 is a high-performance single-engine piston fixed-wing private jet, hailed as the "BMW of the skies," favored by aviation enthusiasts for its superior safety, comfort, and stylish appearance. It is equipped with a whole-aircraft parachute and airbag seatbelts to ensure flight safety. Employing a tricycle landing gear structure, its steering cup is the core load-bearing component of the nose landing gear steering mechanism, while the support ring plays a crucial role in positioning and protection. The assembly precision of both directly affects the aircraft's landing gear steering agility and flight safety. Currently, the disassembly of the steering cup and support ring of general aviation aircraft landing gear often relies on general-purpose tools and traditional processes, which have certain technical limitations. For interference-fit steering cups, there is a lack of specialized removal tools, relying on manual hammering or brute force for disassembly, leading to cup deformation, wear on mating surfaces, and affecting assembly precision. The disassembly of the support ring also relies on external hammering, which can easily damage components. The disassembly and installation process lacks standardized operating procedures, resulting in chaotic steps, low efficiency, and difficulty in ensuring the operational stability of the landing gear turning mechanism after disassembly and installation. Therefore, a disassembly device for the turning axle cup and support ring on the nose landing gear of the Cirrus SR20-G6 is needed. Summary of the Invention

The vehicle body 11 is also provided with equidistant moving components 13, which include wheels, a self-locking component, and a drive component.

[0018] How to use this invention: In the initial state: The third hydraulic rod 15, the electric push rod 36, the first hydraulic rod 38, and the second hydraulic rod 31 are all in a fully retracted state. The semi-ring assemblies 64 are not fully engaged, and the centers of the second hydraulic rod 31 and the receiving groove 34 are not located between the semi-ring assemblies 64.

[0019] When the user wants to use this device, the user needs to drive the moving component 13 through the control terminal 12 to start it. The moving component 13 then moves the vehicle body 11 to the landing gear that needs to be removed. At this time, the landing gear, along with the landing gear connecting rod, is removed from the aircraft and fixed by external fixing components, thus stabilizing the landing gear and the landing gear connecting rod. The vehicle body 11 is now positioned in front of the landing gear to be removed, ensuring that the center of the first pad 41 and the heat-conducting semi-ring 44 is aligned with the center of the landing gear connecting rod and the landing gear shaft hole. The user then manually locks the self-locking component inside the moving component 13, and then manually starts the connection with the third connecting pipe through the control terminal 12. When the oil pump connected to 17 starts, the oil pump in the oil assembly 18 will pump oil into the third connecting pipe 17 through the corresponding pipeline. This oil then enters the corresponding third hydraulic rod 15 through the third connecting pipe 17, causing the third hydraulic rod 15 to extend under the action of the oil. This allows the outrigger 16 to contact the ground, making the vehicle body 11 more stable. Then, according to the actual height, the user drives the second motor 22 through the control terminal 12. After the second motor 22 starts, its motor shaft will drive the screw 23 to rotate, thereby controlling the height of the lifting platform 25 through the rotation of the screw 23. The user then adjusts the lifting platform 25 to approximately the desired height. The bottom surface of the heat-conducting semi-ring 44 should be aligned with the top surface of the turning shaft cup. Then, the user drives the electric push rod 36 through the control terminal 12. After the electric push rod 36 is activated, it will begin to extend. As the electric push rod 36 extends, it will cause the two semi-ring assemblies 64 to come together until the semi-ring plates 40 and the heat-conducting semi-ring 44 within the two semi-ring assemblies 64 are aligned and spliced ​​together. The first mating groove 42 on the semi-ring plate 40 is inserted by the first mating protrusion 43 on the other semi-ring plate 40, and the second mating groove 46 on the heat-conducting semi-ring 44 is inserted by the second mating protrusion 45 on the other heat-conducting semi-ring 44, thereby making the two semi-ring assemblies 64 mutually... After the connection is complete, the two semi-ring plates 40 and the heat-conducting semi-ring 44 each form a complete ring. The user then restarts the second motor 22 according to the actual situation, thereby controlling the raising and lowering of the lifting platform 25. Through the raising and lowering of the lifting platform 25, further refinement is achieved, ensuring that the bottom surface of the heat-conducting semi-ring 44 is completely in contact with the top surface of the turning axle cup. The landing gear connecting rod is positioned between the same pair of semi-ring plates 40 and the heat-conducting semi-ring 44, with the first pad 41 and the second pad 47 in contact with the surface of the landing gear connecting rod. The user then activates the heating component 48 through the control terminal 12, which heats the heat-conducting semi-ring 44.Heating begins on the adhesive between the steering axle cup and the landing gear connecting rod, causing it to gradually melt. However, to prevent excessive heat from damaging the coating on the surface of the steering axle cup and the landing gear connecting rod, the stability of the heating assembly 48 is limited, preventing complete melting of the adhesive. After a certain heating time, heat is transferred to the steering axle cup via the heat-conducting semi-ring 44, causing partial melting of the adhesive between the steering axle cup and the landing gear connecting rod. Then, the control terminal 12 activates the oil pump connected to the first connecting pipe 39 within the oil assembly 18, causing oil from the oil assembly 18 to flow into the first connecting pipe 39, thereby... Connecting pipe 39 enters the first hydraulic rod 38, causing the first hydraulic rod 38 to extend. This extension of the first hydraulic rod 38 will move the semi-ring plate 40 upwards. Since the landing gear connecting rod is not a straight rod but a round rod with bends, the semi-ring plate 40 and the first pad 41 will come into contact with the bends of the landing gear connecting rod during their upward movement, thus pressing against the landing gear connecting rod and applying an upward pushing force. Under this external force, the partially melted adhesive on the landing gear connecting rod will separate from the steering cup. After the landing gear connecting rod separates from the steering cup, the user observes that the landing gear connecting rod has left the steering cup. Then, the control terminal 12 drives the electric... When the electric push rod 36 is activated, it begins to retract, separating the two semi-ring assemblies 64. The semi-ring plate 40 and the heat-conducting semi-ring 44 are no longer a single ring. The user then manually removes excess screws using tools and removes the landing gear connecting rod, the turning axle cup, and any excess parts. The first hydraulic rod 38 is also reset under the control of the control terminal 12. At this point, the user activates the first motor 27 via the control terminal 12. After activation, the motor shaft of the first motor 27 drives the gear 28 to rotate, thereby rotating the rotating rod 29. This aligns the centerline of the second hydraulic rod 31 and the receiving groove 34 with the centerline of the landing gear shaft hole. The user then... The control terminal 12 starts the oil pump corresponding to the second connecting pipe 32 within the hydraulic assembly 18. Once started, the oil pump supplies oil to the second connecting pipe 32, which in turn supplies oil to the second hydraulic rod 31, causing the second hydraulic rod 31 to extend. After the second hydraulic rod 31 extends, the push plate 35 enters the landing gear shaft hole, pushing out the support ring and other components within the landing gear shaft hole. These components, pushed out by the push plate 35, fall onto the receiving groove 34 under gravity, preventing damage from falling from a height. Then, the user drives the corresponding oil pump via the control terminal 12, causing the third hydraulic rod 15 and the second hydraulic rod 31 to reset.The control terminal 12 drives the first motor 27 to reset the rotating rod 29, and the self-locking of the moving component 13 is manually released, allowing the vehicle body 11 to move away from the disassembly point.

The control terminal (12) is used to control the starting of the moving component (13), the oil pump in the oil component (18), the electric push rod (36), the first motor (27), the second motor (22), and the heating component (48).

8. A method for disassembling a landing gear disassembly device according to any one of claims 1-7, characterized in that: When the user wants to use this device, the second motor (22) is started via the control terminal (12). After the second motor (22) is started, its motor shaft will drive the screw (23) to rotate, thereby controlling the height of the lifting platform (25) through the rotation of the screw (23). Then the user roughly adjusts the lifting platform (25) to the approximate height, so that the bottom surface of the heat-conducting semi-ring (44) is aligned with the top surface of the turning shaft cup. Then the user drives the electric push rod (36) to start via the control terminal (12). The two semi-ring plates (40) and the heat-conducting semi-ring (44) each form a complete ring. Then the user can then adjust the height according to the actual situation. The second motor (22) is restarted again under the actual situation, so that the bottom surface of the heat-conducting semi-ring (44) is completely in contact with the top surface of the turning axle cup. The heating component (48) is started through the control terminal (12), and then the control terminal (12) will drive the oil pump connected to the first connecting pipe (39) in the oil component (18) to start, so that the first hydraulic rod (38) begins to extend. During the upward movement of the semi-ring plate (40) and the first pad plate (41), they will come into contact with the bend of the landing gear connecting rod, thereby abutting the landing gear connecting rod. Under the action of external force, the landing gear connecting rod with partially melted adhesive will be separated from the turning axle cup.
