Description

Technical Field

[0001] This invention mainly relates to the field of airborne product disassembly and assembly technology, specifically to an aircraft airborne product disassembly and assembly device. Background Technology

[0002] In current aviation equipment maintenance practices, the disassembly and assembly of airborne products (such as large electro-optical targeting pods, electronic warfare pods, radar compartments, heavy training missiles, or special mission payloads) carried by large aircraft such as bombers generally follow traditional hoisting operation methods. Specifically, existing technologies typically rely on fixed facilities or large mobile equipment: in a suitable hangar, operators need to use overhead cranes; in field stations or outdoor environments, cranes or other lifting equipment must be mobilized. During operations, lifting tools (such as slings and wire ropes) must be connected to the pre-set lifting points of the airborne products. Only through the lifting and movement of the overhead crane or crane, combined with the manual support, traction, and command of multiple ground crew members, can the heavy products be unloaded from the aircraft's mounting points or bays, or the reverse installation procedure be performed.

[0003] This traditional hoisting method has revealed many significant defects and limitations in practical applications: First, it is highly dependent on special equipment and specific sites. Operations must rely on large special support equipment such as overhead cranes or gantry cranes, which severely restricts the availability of equipment and the constraints of specific sites. This greatly limits the flexibility and rapid response capability of support work, making it difficult to meet the emergency support needs of forward airports or poorly equipped sites during wartime.

[0004] Secondly, the entire hoisting process requires the coordinated efforts of multiple ground crew members, each responsible for operating the crane, observing and positioning, manually stabilizing the product, and providing communication and command. This complex personnel coordination and the transmission of audio-visual commands not only make the operation cumbersome and inefficient, but also introduce significant safety risks due to direct human intervention in the movement of heavy loads. The risk of collisions between personnel and equipment or aircraft remains constant.

[0005] Finally, the low operational precision easily leads to equipment damage. Using flexible slings for aerial transport makes the load (airborne products) highly susceptible to uncontrolled swaying, rotation, and shaking. Frequent minor bumps and vibrations can easily cause hidden or obvious damage to the delicate electronic components, optical parts, and aircraft interfaces inside the airborne products, affecting equipment reliability and lifespan, and may even cause flight malfunctions due to improper installation. Summary of the Invention

[0006] 1. The technical problem that the invention aims to solve: The present invention provides an aircraft airborne product disassembly and assembly device to solve the technical problems existing in the background art.

[0007] 2. Technical Solution: To achieve the above objectives, the technical solution provided by this invention is as follows: an aircraft onboard product assembly and disassembly device, comprising a mobile platform, with fixing mechanisms respectively arranged at the four corners of the mobile platform, a horizontal slide rail arranged on the top of the mobile platform along the horizontal direction, a mobile platform slidably connected to the horizontal slide rail, a longitudinal track arranged on the top of the mobile platform along a direction perpendicular to the horizontal slide rail, a lifting mechanism slidably connected to the longitudinal track, a swing support platform connected to the top of the lifting mechanism, and a support tray for supporting the onboard product arranged on the top of the swing support platform. In this embodiment, when using this device to install or disassemble aircraft onboard products, the operator first moves the device to below the aircraft fuselage via the mobile platform, so that the support tray is approximately located below the onboard product to be operated. Subsequently, the fixing mechanisms at each corner are activated to securely lock the mobile platform in the working position. Then, the lifting mechanism is controlled to drive the swing support platform and support tray to rise until they are close to the bottom of the onboard product. By controlling the lateral position of the mobile platform and the longitudinal position of the lifting mechanism, precise positioning of the support tray in two mutually perpendicular directions in the horizontal plane can be achieved. Based on this, by adjusting the swing angle of the swing support platform around the hinge axis, the spatial posture of the support plate can be further adjusted to achieve optimal fit and alignment between its surface and the bottom contour or installation interface of the airborne product. Through the coordinated adjustment of the above seven degrees of freedom (lateral, vertical, lifting, and swing), the support plate can be precisely adapted to the spatial position and angle requirements of the airborne product, thereby providing stable and reliable support and positioning for the product's disassembly or installation.

[0008] This equipment integrates a mobile platform, multi-directional sliding rails, a lifting mechanism, and a swing support platform, enabling flexible and precise adjustment of the support and positioning device in multiple directions during the disassembly and assembly of aircraft onboard products. Its fixing mechanism ensures the stability of the working foundation, avoiding safety risks caused by equipment slippage. The multi-degree-of-freedom adjustment capability allows workers to quickly and accurately align the support tray with onboard products in complex spatial positions, significantly improving the alignment accuracy and operational efficiency of disassembly and assembly operations, and reducing the labor intensity of operators. Furthermore, the equipment is compact, mobile, and highly versatile, suitable for supporting onboard products in different locations on various aircraft models, thus contributing to improved overall efficiency of aircraft maintenance work.

[0009] Furthermore, the fixing mechanism includes inclined support members fixedly connected to the four corners of the mobile platform. The inclined support members extend in a downward direction and have internal threaded holes at their ends. A threaded lifting rod is threaded into the internal threaded holes. The top of the threaded lifting rod is provided with an operating handle, and its bottom end is connected to a fixed base.

[0010] Furthermore, the transverse slide rail includes a pair of parallel and symmetrically arranged dovetail grooves, and the bottom of the moving platform is provided with a sliding part adapted to the dovetail grooves to achieve a sliding connection; a moving groove is provided along its length in the middle area between the two dovetail grooves, and a moving rack is slidably accommodated in the moving groove, and its top is fixedly connected to the bottom of the moving platform; the moving platform has a rotating hole at the lower position corresponding to the middle of the moving groove, and a rotating gear is rotatably installed in the rotating hole through a rotating shaft, one end of the rotating shaft extends to the outside of the moving platform and is connected to a rotating handle, and the upper part of the rotating gear extends into the moving groove and meshes with the moving rack.

[0011] Furthermore, the top of the moving platform is provided with the longitudinal track, which includes a pair of parallel and symmetrically arranged dovetail grooves; the base plate of the lifting mechanism is provided with a slide rail that slides in cooperation with the dovetail grooves; a pair of convex support blocks are symmetrically arranged on the moving platform, and a rotating screw is rotatably supported between the two convex support blocks through a bearing, one end of the rotating screw extending to the outside of one of the convex support blocks and connected to a working handle; the base plate of the lifting mechanism is fixedly connected with a transmission nut that threadedly engages with the rotating screw.

[0012] Furthermore, the lifting mechanism includes a hydraulic scissor-type lifting platform mounted on the base plate, and a fine-tuning platform mounted on top of the hydraulic scissor-type lifting platform; the fine-tuning platform is a manually operated scissor-type lifting structure, and its top is connected to the swing support platform.

[0013] Furthermore, the top of the swing support platform is symmetrically provided with support protrusions on both sides, and the support protrusions are hinged to the corresponding positions of the support plate, so that the support plate can rotate around the hinge axis; a first mounting seat is fixedly provided on one side of the middle of the swing support platform, a drive screw is arranged laterally and threadedly connected to the first mounting seat, and one end of the drive screw is rotatably connected to a concave connecting block; the concave connecting block is rotatably connected to one end of a sliding bar, and the sliding bar is provided with a groove along its length; on the side of the swing support platform opposite to the first mounting seat, two parallel and symmetrical second mounting seats are provided, a support roller is rotatably installed between the two second mounting seats, and the support roller rolls in the groove of the sliding bar; one end of a support bar is rotatably connected to the other end of the sliding bar, and the other end of the support bar is rotatably connected to a third mounting seat, and the third mounting seat is fixedly provided at the bottom of the support plate.

[0016] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this invention has the following advantages: This invention is rationally designed. By integrating a mobile platform, multi-dimensional slide rails, and multi-stage lifting and swinging mechanisms, it achieves coordinated and precise adjustment of the support tray in seven degrees of freedom in space. This allows the equipment to quickly adapt to airborne product interfaces at different positions, angles, and heights on the bottom of the aircraft, significantly improving the alignment accuracy and efficiency of disassembly and assembly operations.

[0017] The manual screw-locking fixing mechanism, along with the precision transmission design of integrated gear rack, lead screw and nut, ensures the absolute stability of the work platform while achieving reliable self-locking and smooth fine-tuning in all directions. The operation is intuitive and requires no external power, taking into account safety, reliability and economy.

[0018] The composite lifting and linkage angle adjustment mechanism combines large-stroke coarse adjustment with high-precision fine adjustment, effectively resolving the contradiction between rapid positioning and precise alignment of heavy-duty equipment. Its compact overall structure facilitates easy movement and deployment, significantly reducing the labor intensity of operators. Its strong versatility effectively ensures the overall efficiency and safety of aircraft maintenance operations.

[0027] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0028] See attached document Figure 1-6 An aircraft onboard product assembly / disassembly device includes a mobile platform 1, with fixing mechanisms 2 at each of the four corners of the mobile platform 1. A horizontal slide rail 3 is horizontally mounted on the top of the mobile platform 1, and a mobile platform 4 is slidably connected to the horizontal slide rail 3. A longitudinal track 5 is vertically mounted on the top of the mobile platform 4, and a lifting mechanism 6 is slidably connected to the longitudinal track 5. A swing support platform 7 is connected to the top of the lifting mechanism 6, and a support tray 8 for supporting the onboard product is mounted on the top of the swing support platform 7. In this embodiment, when using this device to install or disassemble aircraft onboard products, the operator first moves the device via the mobile platform 1 to below the aircraft fuselage, so that the support tray 8 is approximately located below the onboard product to be operated. Then, the fixing mechanisms 2 at each corner are activated to securely lock the mobile platform 1 in the working position. Next, the lifting mechanism 6 is controlled to drive the swing support platform 7 and the support tray 8 upwards until they approach the bottom of the onboard product. By controlling the lateral position of the moving platform 4 and the longitudinal position of the lifting mechanism 6, precise positioning of the support plate 8 in two mutually perpendicular directions within the horizontal plane can be achieved. Furthermore, by adjusting the swing angle of the swing support platform 7 around the hinge axis, the spatial posture of the support plate 8 can be further adjusted, ensuring its surface achieves optimal fit and alignment with the bottom contour or mounting interface of the airborne product. Through the coordinated adjustment of these seven degrees of freedom—lateral, vertical, lifting, and swing—the support plate 8 can precisely adapt to the spatial position and angle requirements of the airborne product, thereby providing stable and reliable support and positioning for product disassembly or installation.

[0029] This equipment integrates a mobile platform 1, multi-directional sliding rails, a lifting mechanism 6, and a swing support platform 7, enabling flexible and precise adjustment of the support and positioning device in multiple directions during the disassembly and assembly of aircraft onboard products. Its fixing mechanism 2 ensures the stability of the working foundation, avoiding safety risks caused by equipment slippage. The multi-degree-of-freedom adjustment capability allows workers to quickly and accurately align the support tray 8 with onboard products in complex spatial positions, significantly improving the alignment accuracy and operational efficiency of disassembly and assembly operations, and reducing the labor intensity of operators. Furthermore, the equipment is compact, mobile, and highly versatile, suitable for supporting onboard products in different locations on various aircraft models, thus contributing to improved overall aircraft maintenance efficiency.

[0030] The fixing mechanism 2 includes inclined support members 21 fixedly connected to the four corners of the mobile platform 1. The inclined support members 21 extend in a downward direction and have internal threaded holes at their ends. A threaded lifting rod 22 is threaded into the internal threaded holes. The top of the threaded lifting rod 22 is provided with an operating handle 23, and its bottom end is connected to a fixed base 24. In this embodiment, after the equipment is moved to the predetermined working position, the operator operates the fixing mechanism 2 at the four corners in sequence. By rotating each operating handle 23, the corresponding threaded lifting rod 22 is driven to rotate downward, so that the fixed base 24 at its bottom end smoothly contacts and presses against the ground. Because the inclined support 21 provides a stable force transmission path, continued rotation of the operating handle 23 can apply sufficient preload, generating strong static friction between the fixed chassis 24 and the ground. Simultaneously, it slightly lifts the moving platform 1, partially or completely lifting its wheels off the ground, thus reliably locking the entire device to the ground and eliminating any possibility of slippage or swaying. The fixing mechanism 2, through the combination of the inclined support and the spiral lifting structure, achieves rapid and stable locking and leveling of the equipment. Its structure is simple and reliable, with low manufacturing costs, and requires no external power source; strong locking force can be generated manually. The fixed chassis 24 is typically a round or square metal plate, and its lower surface can be machined with anti-slip textures or inlaid with a material with a high coefficient of friction to increase friction with the ground.

[0031] The transverse slide rail 3 includes a pair of parallel and symmetrically arranged dovetail grooves 31. The bottom of the moving platform 4 is provided with a sliding part adapted to the dovetail grooves 31 to achieve a sliding connection. A moving groove 32 is provided in the middle area between the two dovetail grooves 31 along its length direction. A moving rack 33 is slidably accommodated in the moving groove 32, and its top is fixedly connected to the bottom of the moving platform 4. The moving platform 1 has a rotating hole at the lower position corresponding to the middle of the moving groove 32. A rotating gear 34 is rotatably installed in the rotating hole through a rotating shaft. One end of the rotating shaft extends to the outside of the moving platform 1 and is connected to a rotating handle 35. The upper part of the rotating gear 34 extends into the moving groove 32 and meshes with the moving rack 33. In this embodiment, when it is necessary to adjust the position of the moving platform 4 and the upper support mechanism on the transverse slide rail 3, the operator drives the rotating shaft and the rotating gear 34 fixed thereon to rotate synchronously by rotating the handle 35. Since the rotating gear 34 and the moving rack 33 are meshed, the rotational motion of the gear is converted into the linear motion of the moving rack 33 along the moving groove 32. Because the moving rack 33 is fixedly connected to the moving platform 4, it drives the entire moving platform 4, lifting mechanism 6, swing support platform 7, and support plate 8 to move precisely laterally along the direction defined by the dovetail groove 31. The dovetail groove 31 ensures the linear accuracy and smooth operation of the movement process.

[0032] The top of the movable platform 4 is provided with the longitudinal track 5, which includes a pair of parallel and symmetrically arranged dovetail grooves 31. The base plate of the lifting mechanism 6 is provided with a slide rail that slides with the dovetail grooves 31. A pair of convex support blocks 41 are symmetrically arranged on the movable platform 4. A rotating screw 42 is rotatably supported between the two convex support blocks 41 by bearings. One end of the rotating screw 42 extends to the outside of one of the convex support blocks 41 and is connected to a working handle 43. The base plate of the lifting mechanism 6 is fixedly connected with a transmission nut that is threadedly engaged with the rotating screw 42. In this embodiment, when it is necessary to adjust the position of the lifting mechanism 6 and its upper components in the horizontal and longitudinal direction, the operator rotates the working handle 43. The rotational torque of the handle drives the rotating screw 42 to rotate synchronously under the support of the bearings of the two convex support blocks 41. Since the transmission nut, which meshes with the rotating lead screw 42, is fixedly connected to the base plate of the lifting mechanism 6, and the entire lifting mechanism 6 is restricted by the longitudinal dovetail groove guide rail 31, it can only move horizontally. Therefore, the rotational motion of the lead screw 42 is converted into linear displacement of the transmission nut and the entire lifting mechanism 6 along the direction of the dovetail groove 31 through the threaded pair. By rotating the working handle 43 clockwise or counterclockwise, the forward or backward movement of the lifting mechanism 6 can be precisely controlled. Through the combination of the lead screw nut and the precision dovetail groove guide rail 31 in the horizontal longitudinal direction, high-precision and stable adjustment of the position of the lifting mechanism 6 is achieved. The lead screw nut transmission has the advantages of smooth transmission, reliable self-locking, and easy fine adjustment, allowing for precise position alignment.

[0033] The lifting mechanism 6 includes a hydraulic scissor lift platform 61 mounted on the base plate and a fine-tuning platform 62 mounted on top of the hydraulic scissor lift platform 61. The fine-tuning platform 62 is a manually operated scissor lift structure, and its top is connected to the swing support platform 7. In this embodiment, when disassembling and assembling the airborne product, the hydraulic system of the hydraulic scissor lift platform 61 is first controlled to drive it to lift or lower, quickly adjusting the swing support platform 7 and its support plate 8 to the approximate height position of the target product. This process is coarse adjustment. When approaching the target height, to achieve further precise alignment, the manual drive mechanism of the fine-tuning platform 62 is operated, using its lead screw or worm gear transmission for fine adjustment, so that the height position of the support plate 8 and the installation interface of the airborne product achieve millimeter-level or even higher alignment accuracy. This solution adopts a two-stage lifting design combining hydraulic and manual operation, which has the advantages of large stroke, high efficiency, and high precision. The hydraulic scissor lift platform 61 can bear heavy weights, lift smoothly and powerfully, and can quickly cover a large working height range, significantly improving the initial positioning efficiency of the equipment. The upper fine-tuning platform 62 provides stepless and precise height fine-tuning capabilities. Its mechanical transmission structure has a self-locking characteristic, which can stably maintain the position after adjustment, ensuring the accuracy and reliability of the final positioning. This composite design effectively solves the contradiction between rapid response and fine adjustment that is difficult to achieve with traditional single lifting mechanisms 6. It is particularly suitable for the characteristics of aircraft airborne product disassembly and assembly operations with strict requirements for support height and diverse working conditions, greatly improving the convenience of operation and the final alignment quality. It should be noted that the hydraulic scissor-type lifting platform 61 and the fine-tuning platform 62 adopt existing technology, which will not be described in detail here.

[0034] The swing support platform 7 has symmetrical support protrusions 71 on both sides of its top. The support protrusions 71 are hinged to the support plate 8 at corresponding positions, allowing the support plate 8 to rotate around the hinge axis. A first mounting seat 72 is fixedly provided on one side of the middle of the swing support platform 7. A drive screw 73 is arranged laterally and threadedly connected to the first mounting seat 72. One end of the drive screw 73 is rotatably connected to a concave connecting block 74. The concave connecting block 74 is rotatably connected to one end of a sliding strip 75. The sliding strip 75 has a groove along its length. On the side of the swing support platform 7 opposite to the first mounting seat 72, there are two parallel and symmetrical second mounting seats 76. A support roller 77 is rotatably installed between the two second mounting seats 76, and the support roller 77 rolls within the groove of the sliding strip 75. One end of a support strip 78 is rotatably connected to the other end of the sliding strip 75, and the other end of the support strip 78 is rotatably connected to a third mounting seat 79. The third mounting seat 79 is fixedly provided at the bottom of the support plate 8. In this embodiment, when the working tilt angle of the support plate 8 needs to be adjusted to adapt to the mounting surface of the airborne product, the operator rotates the drive screw 73. Since the drive screw 73 is threadedly engaged with the fixed first mounting seat 72, the rotational motion is converted into the axial forward and backward movement of the screw itself. The forward and backward movement of the screw tip pushes or pulls the front end of the sliding bar 75 through the concave connecting block 74, causing the sliding bar 75 to move back and forth along its length. The groove in the middle of the sliding bar 75 forms a rolling engagement with the fixed support roller 77, constraining the movement trajectory of the sliding bar 75. The displacement of the rear end of the sliding bar 75 is transmitted to the third mounting seat 79 at the bottom of the support plate 8 through the support bar 78. Since the rear side of the support plate 8 is limited by the hinge shaft, the change in the length of the support bar 78 is directly converted into a torque, driving the support plate 8 to tilt upward or downward around the rear hinge axis, thereby achieving stepless and continuous adjustment of its pitch angle. The direction of rotating the drive screw 73 determines the direction of angle adjustment.

[0035] The top edge of the mobile platform 1 is equipped with a safety railing 91. In this embodiment, the safety railing 91 serves as a passive physical protective barrier, and its working principle is intuitive and reliable. When the equipment is in place and operations are commenced, operators need to climb onto the top of the mobile platform 1 to observe the equipment status, make local adjustments, or assist in operations. At this time, the safety railing 91 surrounding the platform edge constitutes a clear boundary, effectively preventing unintentional approach or falls caused by slipping, thus confining operational activities within a safe platform area.

[0036] A towing column 92 is rotatably connected to one side of the mobile platform 1. A connecting ring 93 is provided at the end of the towing column 92. In this embodiment, when it is necessary to move the equipment a long distance or adjust its position, the operator can connect the hook of a trailer, tractor, or other towing tool to the connecting ring 93. By applying external traction force to the connecting ring 93 and transmitting it to the mobile platform via the towing column 92, the entire equipment can be easily and smoothly moved.

[0037] The above-described embodiments are merely illustrative of certain implementations of the present invention, and are described in a relatively specific and detailed manner. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
