Description

Technical Field

[0001] This application relates to the technical field of superconducting maglev vehicles, and particularly to a composite material equipment mounting plate applicable to superconducting maglev vehicles. Background Art

[0002] As a new type of rail transit system, a superconducting electric maglev vehicle has the ability to travel at ultra-high speeds. The equipment mounting plate, as an important structural part of the vehicle, provides an installation interface for in-cabin equipment of the vehicle and bears the high dynamic vibration loads generated during the operation of the vehicle as well as the inertial loads generated during the acceleration and deceleration of the equipment. The equipment mounting plate itself has a certain rigidity and strength to ensure that it can withstand the action of various loads without permanent deformation and fatigue damage during its service life. When the magnetic field strength is constant, the smaller the weight of the vehicle and the greater the suspension height, the higher the designed speed. Therefore, the structure of the vehicle should be designed as lightweight as possible.

[0003] In the prior art, there is an equipment mounting plate made of aluminum alloy, which is integrally formed by welding an aluminum alloy I-beam as the load-bearing longitudinal beam and a plate as the mounting cross beam. Due to the phenomena of reduced material strength at the weld and difficulty in controlling welding deformation in aluminum alloy welding, the existing aluminum alloy equipment mounting plate has problems such as low strength safety factor, large weight, and small stiffness.

[0004] For example, in the patent with the publication number CN 204341047U, a hydraulic walking self-propelled equipment train is proposed, in which the vehicle body is the equipment bearing structure and is a rectangular frame structure welded by an I-beam and a steel plate. Although the steel plate welding structure in the above patent realizes the structural load-bearing function, for a large-size high-speed maglev vehicle, there are difficulties in controlling the heating welding deformation, resulting in the inability to guarantee the interface dimension accuracy; in addition, since a large amount of metal solder is used in steel plate welding, the structural weight is uncontrollable and the weight is relatively large; at the same time, for a maglev vehicle, using steel with magnetic conductivity characteristics will affect the magnetic field distribution of the superconducting magnet, thereby affecting the suspension and propulsion capabilities.

[0034] In order to make the technical solutions and advantages in the embodiments of the present application clearer, the following further describes the exemplary embodiments of the present application in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0035] In view of the above problems, an embodiment of the present application provides a composite material equipment mounting plate applicable to a superconducting maglev vehicle, as Figure 1-2 shown, its structure includes: an upper housing 1, an inner skeleton 2, and a lower housing 3;

[0036] The upper housing 1 and the lower housing 3 are fixedly connected to form a thin rectangular parallelepiped mounting shell with an internal cavity, and the inner skeleton 2 is fixedly installed inside the thin rectangular parallelepiped mounting shell. Both the upper housing 1 and the lower housing 3 are fixedly connected to the inner skeleton 2.

[0037] The upper shell 1, the inner framework 2, and the lower shell 3 are all made of carbon fiber composite materials.

[0038] The inner framework 2 is installed inside the thin rectangular parallelepiped installation shell formed by the upper shell 1 and the lower shell 3 to ensure high rigidity and strength, and at the same time, structural lightweight can be achieved; the carbon fiber composite material has non-magnetic conductivity characteristics, and its specific strength and specific stiffness are superior to those of metals such as aluminum alloy. Using this material for production can further achieve structural lightweight while ensuring rigidity and strength.

[0039] As Figure 3 shown, the inner framework 2 includes longitudinal beams 21, cross beams 22, and L-shaped corner pieces 23;

[0040] Five longitudinal beams 21 are arranged in parallel, and five cross beams 22 are sequentially connected between every two adjacent longitudinal beams 21 to form a rectangular grid-like framework. The framework structure can not only ensure high rigidity and strength but also is conducive to lightweight design of the structure; as Figure 6 shown, the vertical connection seams between the longitudinal beams 21 and the cross beams 22 are all fixedly connected through L-shaped corner pieces 23. One side of the L-shaped corner piece 23 is riveted to the vertical surface of the longitudinal beam 21 and the other side is riveted to the vertical surface of the cross beam 22. The riveting method of cold connection can reduce overall deformation and further achieve structural lightweight while ensuring the stiffness and strength of the equipment installation plate.

[0041] As Figure 3 shown, two support beams 4 are fixedly installed at both ends of the inner framework 2 along the longitudinal direction. The support beams 4 are arranged parallel to the cross beams 22. As Figure 1 shown in

[0042] As Figure 4 shown, the support beam 4 includes an upper cover plate 41 and a lower cover plate 42. The upper cover plate 41 is a rectangular plate and vertical extension plates 43 are provided below the two sides of its transverse axis. In order to reduce the support height, the lower cover plate 42 is a fish-belly type trough structure with a sunken middle part, and support plates 44 are provided at both transverse ends of the lower cover plate 43. The vertical extension plates 43 of the upper cover plate 41 are sleeved outside the fish-belly type trough of the lower cover plate 42 and riveted to the side plates of the lower cover plate 42. Both transverse ends of the upper cover plate 41 are fixedly connected to the support plates 44 at both transverse ends of the lower cover plate 43. The vertical connection seams between the support beam 4 and the side openings are all fixedly connected through the L-shaped corner pieces 23. The support plates 44 extend outside the thin rectangular parallelepiped installation shell for carrying the equipment installation plate.

[0043] On the upper part of the support plates 44 at the transverse two ends of the lower cover plate 43, there are shallow grooves, and support reinforcement plates 45 are installed in the shallow grooves. The lower end surface of the support reinforcement plate 45 is riveted to the bottom surface of the shallow groove, and its upper end surface is riveted to the end of the upper cover plate 41. The support reinforcement plate 45 can effectively enhance the bearing capacity of the support plate 44 for the equipment mounting plate.

[0044] The two outer longitudinal beams 21 are respectively connected to the corresponding transverse inner side surfaces of the thin rectangular parallelepiped mounting shell through five cross beams 22. The vertical connection seams between the cross beams 22 and the transverse inner side surfaces of the thin rectangular parallelepiped mounting shell are fixedly connected through L-shaped angle pieces 23. One side of the L-shaped angle piece 23 is riveted to the vertical surface of the cross beam 22, and the other side is riveted to the transverse inner side surface of the thin rectangular parallelepiped mounting shell.

[0045] One outer side surface of the lower cover plate 43 is fixedly connected to the end of the longitudinal beam 21 through an L-shaped angle piece 23, and the other outer side surface of the lower cover plate 43 is connected to the corresponding longitudinal inner side surface of the thin rectangular parallelepiped mounting shell through a longitudinal extension beam 24. Both between the longitudinal extension beam 24 and the outer side plate of the lower cover plate 43 and between the longitudinal extension beam 24 and the longitudinal inner side surface of the thin rectangular parallelepiped mounting shell are fixedly connected through L-shaped angle pieces 23.

[0046] Both the longitudinal beams 21 and the cross beams 22 are of beam structures with a channel-shaped or I-shaped cross-section. The upper surfaces of all the longitudinal beams 21 and the cross beams 22 are riveted to the upper shell 1, and the lower surfaces are riveted to the lower shell 3.

[0047] Considering the equipment load-bearing requirements, in this application, the thickness of the positions where the upper shell 1 and the lower shell 3 correspondingly contact the longitudinal beams 21 and the cross beams 22 is greater than that of the remaining parts, that is, longitudinal and transverse thickening areas are arranged on the upper shell 1 and the lower shell 3. On the one hand, it is convenient for contact connection and fixation, and on the other hand, it can increase their load-bearing performance.

[0048] On the vertical lower surface of the upper shell 1, a plurality of first embedded parts with central threaded holes are riveted. Through holes corresponding to the first embedded parts are provided on the upper shell 1, and a lifting seat is fixedly installed on the first embedded part through bolts. The lifting seat is a lifting device for the equipment mounting plate, and it needs to have sufficient strength to realize the lifting of the equipment mounting plate under the full-load state, and is fixed on the first embedded part of the upper shell 1 through bolts.

[0049] On the vertical upper surface of the lower shell 3, a plurality of second embedded parts with central threaded holes are riveted. Through holes corresponding to the second embedded parts are provided on the lower shell 3, and a transverse shock absorber mounting seat 6, a longitudinal shock absorber mounting seat 7, and a vertical shock absorber mounting seat 8 are respectively fixedly installed on the plurality of second embedded parts through bolts. The transverse shock absorber mounting seat 6, the longitudinal shock absorber mounting seat 7, and the vertical shock absorber mounting seat 8 are installation interfaces for the suspension device of the suspension frame, and are fixed on the second embedded parts of the lower shell 3 through bolts to bear the dynamic load of the suspension device. As Figure 1As shown in FIG, two lateral shock absorber mounting seats 6, two longitudinal shock absorber mounting seats 7, and four vertical shock absorber mounting seats 8 are installed on the vertical lower surface of the lower shell 3.

[0050] The structures of the first embedded part and the second embedded part are as follows: Figure 5 The π-shaped structure is shown. When pre-embedded, the embedded parts are fixed on the shell surface of the upper and lower shells located inside the thin rectangular installation shell with core-pulling rivets, and then wrapped with carbon fiber prepreg. The middle part is equipped with drilled threaded holes for fixed installation of the equipment.

[0051] The lifting seat, the lateral shock absorber mounting seat 6, the longitudinal shock absorber mounting seat 7, the vertical shock absorber mounting seat 8, the first embedded part and the second embedded part in the present application are all aluminum alloy machined parts.

[0052] like Figure 1 As shown in the figure, the two longitudinal outer sides of the thin rectangular installation shell are fixedly installed with a grounding copper bar 9, the cross section of the grounding copper bar 9 is L-shaped, one side of the grounding copper bar 9 is riveted to the two longitudinal outer sides of the thin rectangular installation shell and the other side is connected to the grounding wire. The grounding copper bar 9 is an equipment grounding device on the equipment installation plate, and various electrical equipment are installed on the equipment installation plate. Due to the poor conductivity of carbon fiber, the grounding copper bar 9 is designed to achieve equipment grounding and equipotential functions.

[0053] The installation steps for this application are as follows:

[0054] Assemble the support beam 4, embed the lower cover plate 42 of the support beam 4 into the upper cover plate 41, and fix the vertical extension plate 43 of the upper cover plate 41 to the side plate of the lower cover plate 42 by riveting to form a hollow beam structure;

[0056] 3. Assemble the inner frame with the upper and lower shells. Assemble the assembled inner frame 2 with the lower shell 3. All the beam ends at the edge of the inner frame 2 are riveted to the inner side of the lower shell 3 through L-shaped angle pieces. The lower surface of the inner frame 2 is directly riveted to the lower shell 3. Rivet the second embedded part to the lower surface of the lower shell 3 and drill threaded holes. Rivet the first embedded part to the upper surface of the upper shell 1 and drill threaded holes. Buckle the upper shell 1 with the first embedded part into the assembled lower shell 3 and inner frame 2 structure.
