Description

Technical Field

[0001] This invention relates to the field of aviation architectural decoration construction technology, specifically to a BIM-based positioning and installation structure for aviation aluminum panels. Background Technology

[0002] With the diversified development of modern aviation hub architectural design, large-area irregularly shaped aviation aluminum panels are widely used in the interior and exterior decoration projects of numerous airport terminals and aviation supporting venues. These aviation aluminum panels generally possess the characteristics of high structural strength, good surface flatness, and strong plasticity, and can adapt to complex architectural shapes such as hyperboloids and irregular sloping surfaces. At the same time, they take into account thermal insulation, sound insulation, and aesthetics, making them one of the core materials for current aviation-related architectural decoration construction.

[0003] Currently, the industry has gradually introduced BIM technology into the aluminum panel construction process. 3D scanning is used to re-measure the main structure, and the BIM model is combined with aluminum panel layout optimization and pre-simulated installation, which improves the installation accuracy of irregularly shaped aluminum panels to some extent. Meanwhile, various aluminum panel installation and positioning devices have emerged on the market. Some devices can achieve initial fixing of aluminum panels through simple telescopic structures, while some clamping devices can complete the clamping and positioning of conventional flat aluminum panels. However, existing technologies still have significant shortcomings in actual aerospace aluminum panel installation scenarios: First, most traditional positioning devices can only achieve displacement adjustment in a single linear direction, and cannot simultaneously complete multi-dimensional linkage adjustment of aluminum plate lifting, 360° plane rotation and longitudinal pitch angle. When faced with a large number of irregular curved and inclined aluminum plate installation scenarios in aviation construction, it is necessary to manually pry and calibrate the position of the aluminum plate repeatedly, which not only results in low installation efficiency, but also easily causes deformation of the aluminum plate surface and scratches on the paint, and the material loss rate remains high for a long time.

[0004] Secondly, existing installation equipment generally does not have a deep integration with the BIM system. It can only rely on manual comparison with BIM drawings to verify the points. It is impossible to obtain the identity information and preset installation parameters of the aluminum plate in real time at the installation site. It is also difficult to transmit the real-time images of the installation process back to the BIM system for dynamic verification. Deviations in the installation process cannot be detected in time, and the cost of subsequent rework and rectification increases significantly.

[0005] Third, conventional aluminum plate clamping devices have a fixed clamping range and can only be adapted to aluminum plates of a single specification. When dealing with aviation aluminum plates of different sizes and curvatures in aviation projects, it is necessary to frequently change the clamps, which cannot quickly complete the adaptive clamping of aluminum plates of multiple specifications, seriously slowing down the overall construction progress. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a BIM-based positioning and installation structure for aviation aluminum plates.

[0028] Example like Figures 1 to 6As shown, motor 101 adopts a three-phase asynchronous servo motor structure, with its output shaft directly and rigidly connected to the power input port of gear commutator 102. As the core power source of the entire device, it provides stable rotational driving force for subsequent lifting actions. Gear commutator 102 uses an SPL spiral bevel gear commutator, internally integrating two sets of 90° meshing spiral bevel gears. Its power input side connects to the output shaft of motor 101, and its two power output ends are coaxially connected to two first transmission shafts 103, achieving a smooth splitting of single-path input power to two-path synchronous output power, ensuring that the rotational speeds of the transmission components on both sides are completely consistent. The first transmission shaft 103 adopts a light shaft structure machined from 45# steel. Its two ends are respectively connected to the output end of gear commutator 102 and the coaxial end of worm gear 104 via rigid couplings, directly transmitting the rotational power output by gear commutator 102 to worm gear 104, avoiding coaxiality deviation during power transmission. The worm gear 104 adopts an involute cylindrical worm structure, which is coaxially fixed to the end of the first drive shaft 103 via a flat key, forming a meshing transmission pair with the worm wheel 105. Utilizing the large reduction ratio characteristic of the worm gear and worm wheel, high-speed rotational power is converted into high-torque, low-speed power, while simultaneously achieving a reverse self-locking function to prevent the lifting mechanism from accidentally falling. The worm wheel 105 adopts an internal gear ring structure made of tin bronze, which is interference-fitted onto one end of the second drive shaft 106, forming a tight mesh with the worm gear 104, converting the rotational power transmitted by the worm gear 104 into the circumferential rotational power of the second drive shaft 106. The second drive shaft 106 adopts a stepped shaft structure with positioning shoulders at both ends. One end is interference-fitted with the worm wheel 105, and the other end is interference-fitted with the first bevel gear 107. It is fixed inside the housing of the drive mechanism 1 via bearing seats, smoothly transmitting the rotational power output by the worm wheel 105 to the first bevel gear 107. The first bevel gear 107 adopts a spur bevel gear structure and is interference-fitted onto the end section of the second transmission shaft 106, forming a 90° meshing transmission pair with the second bevel gear 108. This converts the horizontal rotational power into vertical rotational power, adapting to the vertical arrangement requirements of the ball screw 402. The second bevel gear 108 adopts a spur bevel gear structure with a module matching that of the first bevel gear 107 and is interference-fitted onto the bottom section of the third transmission shaft 109, meshing tightly with the first bevel gear 107. This transmits the vertical rotational power output by the first bevel gear 107 to the third transmission shaft 109. The third transmission shaft 109 adopts a vertically arranged stepped shaft structure. The bottom is interference-fitted with the second bevel gear 108, and the top is connected to the power input shaft of the screw seat 401 via a coupling, directly inputting the rotational power of the second bevel gear 108 into the transmission structure inside the screw seat 401.

[0029] like Figures 1 to 6As shown, the scanner 2 uses a high-resolution QR code scanning module, which is fixed to the top outer side of the housing of the drive mechanism 1 by bolts. The data interface is connected to the main control device through a signal line, which is used to scan the BIM linkage ID card preset on the edge of the aviation aluminum plate in real time and quickly retrieve the preset installation parameters of the BIM model corresponding to the aluminum plate.

[0030] like Figures 1 to 6 As shown, camera 3 uses a 4K high-definition industrial-grade camera module, which is fixed to the side of scanner 2 by a bracket. The video output port is connected to the main control device through a signal cable. It is used to collect real-time images of the entire process of installing aviation aluminum plates and synchronously transmit the image data back to the back-end BIM system to complete dynamic verification.

[0031] like Figures 1 to 6 As shown, the lead screw seat 401 adopts an integrated cast metal shell structure, with an integrated bevel gear transmission pair inside. Its bottom is fixed to the top of the drive mechanism 1's housing by bolts. The power input side connects to the third transmission shaft 109, and the top is vertically mounted with a ball screw 402, providing stable rotational support for the ball screw 402. The ball screw 402 adopts a precision-ground ball screw structure, vertically arranged at the top output end of the lead screw seat 401. Its bottom is connected to the internal transmission structure of the lead screw seat 401 via bearings. The lead screw lever body runs through the lifting block 403 throughout its entire length, providing high-precision vertical lifting guidance for the lifting block 403. The lifting block 403 adopts a block structure integrally milled from aluminum alloy, with a pre-reserved assembly cavity for the lead screw nut 404. Its outer end face is rigidly connected to the base 507 of the rotating mechanism 5 by bolts. The lead screw nut 404 and the ball screw 402 form a threaded transmission engagement, converting the rotational motion of the ball screw 402 into its own vertical linear lifting motion. The lead screw nut 404 adopts a ball screw nut structure that matches the precision of the ball screw 402. It is interference-fitted into the internal assembly cavity of the lifting block 403, forming a rolling fit with the thread raceway of the ball screw 402. This significantly reduces frictional resistance during the lifting transmission process, ensuring the smoothness and positioning accuracy of the lifting action. The limit sleeve 405 adopts a rubber-metal composite buffer sleeve structure. It is interference-fitted into the bottom limit position of the ball screw 402 and axially fixed by a snap ring. It is used to limit the lowest descent position of the lifting block 403, preventing the lifting block 403 from directly impacting the lead screw seat 401 and causing component damage.

[0032] like Figures 1 to 6As shown, the rotating base 501 adopts a U-shaped opening aluminum alloy shell structure, with a reserved mounting cavity for the motor 508 and a rotating cavity for the rotating disk 502. The rear outer side is rigidly connected to the bearing seat 503, and the front opening position forms a rotational fit with the rotating disk 502, providing a stable rotational support for the rotating disk 502. The rotating disk 502 adopts a disc-shaped aluminum alloy structure, with an external gear ring 510 integrally formed on the back. The disk surface is rigidly connected to the base plate 601 of the clamping mechanism 6 via bolts, and the entire assembly is embedded in the rotating cavity of the rotating base 501. Driven by the external gear ring 510, it achieves 360° circumferential rotation, driving the clamped aviation aluminum plate to complete the planar angle adjustment. The bearing seat 503 adopts a metal support structure with a U-shaped slot, rigidly welded to the rear outer wall of the rotating base 501. The slot is rotatably connected to the shaft 504 via a bearing, serving as the rotational fulcrum for the pitch movement of the rotating base 501, ensuring coaxiality during the pitch adjustment process. The shaft 504 adopts a stepped shaft structure with a positioning shoulder, and is rigidly welded upwards to the top rear end of the base 507. The shaft body is embedded in the inner ring of the bearing of the bearing seat 503, forming a rotational engagement with the bearing seat 503, providing rotational support in the tilt direction for the entire rotating seat 501, and adapting to the multi-angle pitch adjustment requirements of aviation aluminum plates. The pin connector 505 adopts a pin-type connector with double-ear slots. One end is hinged to the free end of the electro-hydraulic rod 506 by a pin, and the other end is rigidly fixed to the eccentric position on the back of the rotating disk 502 by bolts, converting the linear extension and retraction power of the electro-hydraulic rod 506 into the pitch and rotational power of the rotating seat 501 around the shaft 504. The electro-hydraulic rod 506 adopts an inclined servo electro-hydraulic rod structure. Its fixed end is hinged to the front mounting bracket of the base 507 via a pin, and its free end is connected to the rotating disk 502 via a pin connector 505. The control line is connected to the main control device via a signal line. Through precise extension and retraction control, it drives the rotating seat 501 to complete the pitch angle adjustment within the range of 0° to 60°. The base 507 adopts an L-shaped aluminum alloy one-piece support structure. The bottom is rigidly fixed to the outer end face of the lifting block 403 by bolts, and the top rear end is rigidly connected to the shaft 504. A hinged support for the electro-hydraulic rod 506 is reserved at the front, serving as the load-bearing base for the entire rotating mechanism 5, synchronously transmitting the lifting power of the lifting block 403 to all upper rotating components. The motor 508 adopts a high-precision stepper servo motor structure, fixed to the mounting cavity inside the rotating seat 501 by bolts. The output shaft end is rigidly fitted with a transmission gear 509, and the control line is connected to the main control device, providing precise rotational driving force for the planar rotation of the rotating disk 502. The transmission gear 509 adopts a spur gear structure that matches the module of the external gear ring 510. It is interference-fitted onto the output shaft of the second motor 508 and forms a tight mesh with the external gear ring 510, transmitting the rotational power of the second motor 508 to the external gear ring 510. The transmission method of the small gear driving the large gear ring achieves smooth rotation with high torque and low speed.The external gear ring 510 adopts an internally concave external gear ring structure that is integrally milled with the rotating disk 502. It meshes with the transmission gear 509 and rotates synchronously under the drive of the transmission gear 509, driving the rotating disk 502 to complete a 360° smooth planar rotation.

[0033] like Figures 1 to 6As shown, the base plate 601 adopts a rectangular high-strength aluminum alloy plate structure. Mounting flanges for electrically controlled hydraulic rods 602 and 603 are reserved on its four edges. The back is rigidly connected to the rotating disk 502 via bolts, serving as the load-bearing base for the entire clamping mechanism 6. This allows all adjustment movements of the rotating mechanism 5 to be synchronously transmitted to the clamped aviation aluminum plate. The electrically controlled hydraulic rod 602 adopts a large-stroke servo hydraulic rod structure, with two rods rigidly fixed to the upper and lower edges of the base plate 601. The free end is rigidly connected to the center plate 604, and the control line is connected to the main control device. Through synchronous or independent telescopic movements, the clamping span in the vertical direction is adjusted to accommodate aviation aluminum plates of different lengths. The three electro-hydraulic rods 603 adopt a short-stroke, high-precision servo hydraulic rod structure, with a total of six rods. Two rods are directly and rigidly fixed to the left and right edges of the base plate 601, and the remaining four rods are rigidly fixed to the left and right sides of the two center plates 604 respectively. The free ends of all the three electro-hydraulic rods 603 are rigidly connected to the mounting plate 605, and the control line is connected to the main control device. The clamping span in the left and right directions can be adjusted by different telescopic combinations to adapt to aviation aluminum plates of different widths. The center plate 604 adopts a rectangular aluminum alloy connecting plate structure, with two plates arranged at the top and bottom. The back is rigidly connected to the free end of the two electro-hydraulic rods 602, and the two sides of the plate are rigidly connected to the fixed ends of the three electro-hydraulic rods 603 respectively. As an intermediate transition carrier, it transmits the telescopic power of the two electro-hydraulic rods 602 to the two electro-hydraulic rods 603 on both sides to achieve synchronous expansion of the clamping length. The assembly plate 605 adopts an L-shaped aluminum alloy mounting plate structure, with a total of 6 plates arranged. Each plate is rigidly connected to the free end of the corresponding electro-hydraulic rod 603. Mounting holes for pneumatic grippers 606 are reserved on the outer side of the plate, providing a stable mounting carrier for the pneumatic grippers 606 and ensuring the contact position accuracy between the grippers and the edge of the aluminum plate. The pneumatic grippers 606 adopt a pneumatic clamping claw structure with anti-slip rubber pads, with a total of 6 sets assembled and fixed to the outer mounting positions of the 6 assembly plates 605. The air circuit interface connects to the built-in miniature air pump, and the control line connects to the main control device. Through pneumatic clamping action, the side edge of the aviation aluminum plate is firmly gripped, preventing slippage and displacement of the aluminum plate during multi-dimensional adjustment. The slide rail 607 adopts a high-precision linear guide structure, which is horizontally fixed to the ground support base below the two bottom assembly plates 605 by bolts. The guide rail groove and the slider 608 form a sliding engagement, providing additional support and guidance for the clamping components at the bottom and preventing sagging deformation of large-sized aerospace aluminum plates during clamping. The slider 608 adopts a linear slider structure with precision matching that of the slide rail 607. It is rigidly fixed to the lower surface of the two bottom assembly plates 605 by bolts and embedded in the groove of the slide rail 607. It slides smoothly along the slide rail 607 synchronously with the extension and retraction of the assembly plates 605, greatly improving the structural stability of the clamping process of large-sized aluminum plates.

[0034] The overall working principle and process of the equipment: Before the device is officially started, the construction personnel first hoist the aviation aluminum plate to be installed to the initial support position of the clamping mechanism 6. The main control device first outputs a control signal to drive the two upper and lower electro-hydraulic rods 602 to extend synchronously, driving the two center plates 604 to move up and down. The clamping span is adjusted to the preset value according to the actual length of the aviation aluminum plate. Then, the main control device controls all the electro-hydraulic rods 603 to extend synchronously, driving the corresponding assembly plate 605 to move to the side of the aluminum plate. The bottom assembly plate 605 will drive the slider 608 to slide smoothly along the slide rail 607 to ensure the synchronicity of the bottom support. Finally, the six sets of pneumatic grippers 606 are precisely attached to the six side points of the aviation aluminum plate. The main control device triggers the pneumatic control signal, and all the pneumatic grippers 606 synchronously complete the clamping action, firmly fixing the edge of the aviation aluminum plate and completing the adaptive clamping process.

[0035] After clamping, the BIM-linked ID card pre-attached to the bottom edge of the aviation aluminum plate will automatically align with the scanning window of scanner 2. Scanner 2 will immediately start scanning and transmit the read ID information to the main control device. The main control device will retrieve the corresponding preset installation parameters of the aluminum plate through the built-in BIM data interface, including core data such as target installation height, plane rotation angle, and pitch tilt angle, to complete the matching and verification of the aluminum plate's identity and installation parameters, thus avoiding the misuse of aluminum plates.

[0036] Next, the aluminum plate lifting process begins. The main control device outputs a start signal to drive motor 101 to start running. The rotational power of motor 101 is directly input to gearbox 102, which distributes the single power into two synchronous rotational power streams through internal spiral bevel gears. These power streams drive the first drive shafts 103 on both sides to rotate synchronously. The two first drive shafts 103 drive the corresponding worm gears 104 to rotate through couplings. The worm gears 104 drive the matching worm wheels 105 to rotate at low speed and high torque through meshing transmission. The worm wheels 105 on both sides synchronously drive the two second drive shafts 106 to rotate coaxially. The first bevel gear 107 at the end of each second drive shaft 106 rotates synchronously, driving the second bevel gear 108 through 90° bevel gear meshing transmission. The rotation converts the horizontal rotational power into vertical rotational power, thereby driving the third drive shaft 109 to rotate synchronously. The third drive shaft 109 inputs power into the transmission structure inside the lead screw seat 401, driving the ball screw 402 at the output end of the lead screw seat 401 to start rotating. Through the rolling engagement with the lead screw nut 404, the ball screw 402 drives the lifting block 403 to move vertically upward smoothly along the rod of the ball screw 402. The lifting block 403 synchronously drives the entire rotating mechanism 5 and the clamping mechanism 6 to lift, smoothly lifting the aviation aluminum plate to the target installation height preset by the BIM system. The limit sleeve 405 at the bottom of the ball screw 402 will provide buffer protection when the lifting block 403 descends to the limit position to avoid hard collision damage to the components.

[0037] Once the aluminum plate is raised to the target height, it enters the plane angle adjustment process. The main control device outputs a control signal to drive the second motor 508 inside the rotating seat 501 to operate. The second motor 508 drives the transmission gear 509 at the output shaft end to rotate. The transmission gear 509 drives the outer gear ring 510 integrally formed on the back of the rotating disk 502 to rotate through meshing transmission. The outer gear ring 510 synchronously drives the rotating disk 502 to complete a 360° precise rotation in the rotating cavity of the rotating seat 501. The rotating disk 502 drives the rigidly connected base plate 601 to rotate synchronously, and finally drives the clamped aviation aluminum plate to complete the plane angle adjustment until the plane angle of the aluminum plate is completely matched with the installation angle preset in the BIM model.

[0038] After the planar angle adjustment is completed, the longitudinal pitch angle adjustment process begins. The main control device outputs a control signal to drive the electro-hydraulic rod 506, which is tilted at the front of the base 507, to perform a telescopic action. When the electro-hydraulic rod 506 extends outward, it pushes the back of the rotating disk 502 to the eccentric position through the pin 505 at the front end, thereby causing the shaft seat 503 at the rear of the rotating seat 501 to rotate backward around the shaft 504 tilted at the top of the base 507, thus achieving the backward tilt adjustment of the aviation aluminum plate. When the electro-hydraulic rod 506 retracts inward, it pulls the rotating disk 502 to drive the rotating seat 501 to rotate forward around the shaft 504, thus achieving the forward tilt adjustment of the aviation aluminum plate. Finally, the longitudinal tilt angle of the aluminum plate is precisely adjusted to the value preset in the BIM model, which is fully compatible with the installation reference surface of irregular curved surfaces and inclined surfaces.

[0039] Throughout the entire process of lifting, rotating, and tilting adjustment, the camera 3 positioned on the side of the scanner 2 continuously captures real-time position images of the aviation aluminum plate. The image data is transmitted back to the main control device in real time and then simultaneously uploaded to the back-end BIM system via a wireless communication module. The BIM system dynamically compares the real-time aluminum plate position data with the preset installation points. Once the position deviation exceeds the allowable threshold, it immediately sends an early warning signal to the main control device. The main control device automatically fine-tunes the action parameters of each actuator until the three-dimensional position of the aluminum plate completely coincides with the preset installation points of the BIM model. Finally, the construction personnel can quickly complete the locking and fixing of the aviation aluminum plate. The entire installation process does not require repeated manual prying and calibration, achieving high-precision automated positioning and installation under BIM linkage.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
