Description

Technical Field

[0001] This application relates to aluminum profile structures, and more particularly to an aluminum profile structure for an aircraft elevator. Background Technology

[0002] As a core component of aviation ground support equipment, the structural performance of aircraft elevators directly affects the safety and efficiency of aircraft maintenance, personnel and material transfer operations. These devices must withstand complex conditions such as alternating loads and environmental corrosion over long periods, thus imposing stringent requirements on structural strength, rigidity, lightweight design, and weather resistance. Their material and structural design has always been a key focus of industry technological research and development.

[0003] In the existing technology, in order to balance lightweight and basic strength, aircraft elevators often use ordinary aluminum alloy profiles as the main frame. This type of profile is formed by extrusion molding. Although its density is only 2.7g / cm³, which can significantly reduce the weight of the equipment, its bending stiffness is relatively insufficient due to the limitation of cross-sectional structural design. Under loads exceeding the rated load, it is prone to permanent deformation, making it difficult to meet the high requirements of aircraft elevators for structural stability.

[0004] To address the issue of insufficient strength in ordinary aluminum alloy profiles, this application proposes an aluminum profile structure for aircraft elevators. By incorporating specific reinforcing structures such as transverse partitions and longitudinal ribs into the profile body, the overall strength and bending stiffness of the profile are enhanced, thereby solving the problem of excessive deformation caused by insufficient structural strength in the prior art. Utility Model Content

[0005] The purpose of this application is to provide an aluminum profile structure for aircraft elevators, which has the advantages of high rigidity and strength, and solves the problem of excessive deformation caused by insufficient strength.

[0006] The aluminum profile structure for an aircraft elevator provided in this application adopts the following technical solution: it includes a main load-bearing component, a reinforcing component and a reinforcing rib component, and a connecting component. The reinforcing component is disposed inside the main load-bearing component, the reinforcing rib component is disposed inside the main load-bearing component, and the connecting component is disposed on both sides of the main load-bearing component. By adopting the above technical solutions, the coordinated arrangement of load-bearing components, reinforcing components, stiffener components and connecting components can form a multi-layered stress support system. The reinforcing components and stiffener components strengthen the structural strength of the main load-bearing components, while the connecting components improve the connection stability of the overall structure from both sides. The cooperation of all parties effectively improves the overall rigidity and deformation resistance of the aluminum profile structure, meeting the load-bearing requirements of the aviation elevator under complex working conditions.

[0007] Preferably, the main load-bearing component includes an upper wing plate, a web plate is provided at the bottom near the middle of the upper wing plate, a lower wing plate is provided at the bottom of the web plate, the reinforcing component is provided on one side of the web plate, and multiple slots are provided at the bottom of the upper wing plate and the top of the lower wing plate.

[0008] By adopting the above technical solution, the combination of the upper flange, web and lower flange in the main load-bearing component forms a stable basic load-bearing structure, and the web vertically connects the upper and lower flanges to distribute the load.

[0009] Preferably, the reinforcing component includes horizontally arranged partitions, and there are three sets of horizontally arranged partitions. A central groove is formed at the center of the three sets of partitions. The central groove is in the shape of an equilateral triangle. The partitions are respectively arranged on both sides of the web.

[0010] By adopting the above technical solution, the transversely arranged partitions in the reinforced component are distributed on both sides of the web, which can provide lateral support to the web and reduce the bending deformation of the web under stress. The equilateral triangular central groove not only reduces weight while ensuring structural stability, but also disperses the load borne by the web through the mechanical properties of the triangle, thereby improving the shear and bending resistance of the web.

[0011] Preferably, the reinforcing rib assembly includes multiple ribs, the surfaces of the multiple ribs are in a cross shape, and each of the multiple ribs is provided with a retaining plate at its top and bottom. The multiple retaining plates are respectively engaged in multiple retaining slots, and the retaining plates are fixedly connected to the upper wing plate and the lower wing plate respectively by a third stud.

[0012] By adopting the above technical solution, the cross ribs of the reinforcing rib assembly have high structural rigidity. The top and bottom plates are snapped into the slots, and with the fixation of the third stud, the ribs are firmly connected to the upper and lower flanges. The cross structure can effectively disperse loads from different directions, significantly enhance the overall bending rigidity of the aluminum profile structure, and reduce the amount of deformation after being subjected to force.

[0013] Preferably, the connecting assembly includes an outer spherical shell and an inner spherical head, the inner spherical head being disposed inside the outer spherical shell, and connecting rods being provided on the surfaces of both the inner and outer spherical heads. Two sets of gripping arms are provided on the surface of the outer spherical shell, and the two sets of gripping arms are respectively fixedly connected to one side of the upper wing plate and the lower wing plate. The inner spherical head is fixedly installed to the outer spherical shell by a second stud, and the two sets of connecting rods are respectively fixedly connected to one side of the rib.

[0014] By adopting the above technical solution, the connecting component can achieve a certain angle adjustment to adapt to different assembly requirements through the cooperation of the outer spherical shell and the inner spherical head. It can also transfer the load to the upper and lower wing plates and ribs through the grab arm and connecting rod. The fixing of the second stud ensures the firmness of the connection, making the force transmission between components more uniform and improving the connection stability and assembly flexibility of the overall structure.

[0015] Preferably, the top of the upper wing plate is provided with a rack, and the bottom of the lower wing plate is provided with a limiting groove, which is adapted to the rack.

[0016] By adopting the above technical solution, the rack of the upper wing plate is matched with the limiting groove of the lower wing plate. When adjacent aluminum profiles are spliced, precise positioning can be achieved through the meshing of the rack and the limiting groove, avoiding displacement or loosening at the splice, improving the continuity of the overall structure and the stability after splicing, and ensuring the smooth transmission of load at the splice.

[0017] Preferably, the lower wing plate and the upper wing plate are provided with connecting plates near the four corners, and the two sets of connecting plates are fixedly installed by first studs.

[0018] By adopting the above technical solution, the connecting plates at the four corners of the upper and lower wing plates are fixed by the first stud, which can form a tighter overall connection between the upper and lower wing plates, enhance their cooperative force-bearing capacity, reduce relative displacement, and thus improve the torsional performance and overall stability of the aluminum profile structure.

[0019] Preferably, a protective groove is provided on one side of both the upper and lower wing plates, and the third stud is located in the protective groove.

[0020] By adopting the above technical solution, the protective groove on one side of the upper and lower wing plates can accommodate the third stud, which can prevent the stud from being directly exposed to the outside and being damaged by external forces such as collision and corrosion, thus ensuring the service life of the second stud.

The reinforcing components and stiffener components strengthen the structural strength of the main load-bearing components, while the connecting components improve the connection stability of the overall structure from both sides. The cooperation of all parties effectively improves the overall rigidity and deformation resistance of the aluminum profile structure, meeting the load-bearing requirements of aircraft elevators under complex working conditions.

The combination of the upper flange 101, web 103, and lower flange 102 in the main load-bearing component 1 forms a stable foundation load-bearing structure. The web 103 is vertically connected to the upper flange 102. The lower flange 102 can distribute the load. The reinforcing assembly 2 includes three sets of transversely arranged baffles 202. A central groove 201 is formed at the center of each set of baffles 202. The central groove 201 is in the shape of an equilateral triangle. The baffles 202 are respectively arranged on both sides of the web 103. The transversely arranged baffles 202 in the reinforcing assembly 2 are distributed on both sides of the web 103, which can provide lateral support to the web 103 and reduce the bending deformation of the web 103 under stress. The equilateral triangular central groove 201 not only reduces weight while ensuring structural stability, but also disperses the load borne by the web 103 through the mechanical properties of the triangle, thereby improving the shear and bending resistance of the web 103. The reinforcing rib assembly 3 includes multiple ribs 301 with intersecting surfaces. Each rib 301 has a retaining plate 302 at its top and bottom, which is engaged in multiple slots 108.

The connecting assembly 4 is connected to the outer spherical shell 401 and the inner ball head 404 by means of the second stud 402. The ball joint 404 allows for angle adjustment to accommodate different assembly requirements, and the load is transferred to the upper and lower wing plates 102 and ribs 301 via the grab arm 403 and connecting rod 405. The fixation of the second stud 402 ensures the connection's firmness, making the force transmission between components more uniform and improving the overall structural connection stability and assembly flexibility. A rack 107 is provided at the top of the upper wing plate 101, and a limiting groove 106 is provided at the bottom of the lower wing plate 102. The limiting groove 106 is compatible with the rack 107. The rack 107 of the upper wing plate 101... The rack 107 is adapted to the limiting groove 106 of the lower flange 102.

A protective groove 5 is provided on one side of both the upper flange 101 and the lower flange 102, and the third stud 303 is located in the protective groove 5. The protective groove 5 on one side of the upper flange 101 and the lower flange 102 houses the third stud 303, which can prevent the stud from being directly exposed to the outside and being damaged by external forces such as collision and corrosion, thus ensuring the service life of the second stud 402.

[0028] The implementation principle of this application embodiment is as follows: When using the aluminum profile structure for the aircraft elevator, the main load-bearing component 1 serves as the basic frame. The upper wing plate 101, the web plate 103, and the lower wing plate 102 are pre-assembled into a stable load-bearing structure. The design of the web plate 103 vertically connecting the upper and lower wing plates 102 can distribute the load during operation, laying the foundation for the overall stress. During assembly, the transverse partitions 202 of the reinforcing component 2 are first installed on both sides of the web plate 103. The three sets of transversely arranged partitions 202, with the help of the central equilateral triangular groove 201, reduce their own weight while dispersing the load through the mechanical properties of the triangle. The load borne by the web 103 forms lateral support to reduce bending deformation after stress. Then, the cross ribs 301 of the reinforcing rib assembly 3 are inserted into the slots 108 at the bottom of the upper flange 101 and the top of the lower flange 102 via top and bottom clamping plates 302, and then fixed with third studs 303. The cross ribs 301 themselves have high rigidity, and their firm connection with the upper and lower flanges 102 effectively disperses loads from different directions, significantly enhancing overall bending stiffness. The connecting assembly 4 is installed on both sides of the main load-bearing assembly 1, and the grab arms 403 of the outer spherical shell 401 are fixed to... On the sides of the upper flange 101 and lower flange 102, the inner ball head 404 is fixed inside the outer spherical shell 401 by the second stud 402. The connecting rod 405 on its surface is connected to the rib 301. This structure allows for a certain angle adjustment to adapt to different assembly requirements. The load is evenly transferred to the upper and lower flanges 102 and the rib 301 through the grab arm 403 and the connecting rod 405, ensuring the stability of force transmission between components. When multiple profiles need to be spliced, the rack 107 at the top of the upper flange 101 and the limiting groove 106 at the bottom of the lower flange 102 engage with each other to achieve precise positioning and avoid splicing at the joint. If displacement or loosening occurs, the upper and lower wing plates 102 are fixed to the first stud 104 by the connecting plates 105 at the four corners, further strengthening the overall continuity after splicing and ensuring that the load is smoothly transmitted at the splice. During operation, the protective groove 5 on one side of the upper wing plate 101 and the lower wing plate 102 houses the third stud 303, which can prevent the stud from being damaged by external forces such as collision and corrosion, and ensure its service life. The overall structure bears the core load through the main load-bearing component 1, and the strengthening component 2 and the reinforcing rib component 3 strengthen the deformation resistance from the inside. The connecting component 4 and the splicing structure improve the stability of the connection and splicing.
