Description

Technical Field

[0001] This application relates to the technical field of cable trays, and more particularly to a marine cable tray. Background Technology

[0002] In marine electrical systems, the proper laying and securing of marine cables is crucial, affecting not only the normal operation of the system but also the overall safety and reliability of the vessel. As a key component supporting and securing cables, the rationality of the cable tray's structure and its performance directly determine the quality and efficiency of cable laying.

[0003] Currently, marine cable trays on the market are mainly divided into two types: single-layer and multi-layer. Single-layer marine cable trays are relatively simple in structure and easy to install, and can meet basic cable laying requirements to a certain extent. However, they have a significant drawback: low cable capacity. As ship electrical systems become increasingly complex, the number of cables required to be laid is constantly increasing. The limited capacity of single-layer trays often fails to meet actual needs, leading to overly dense cable laying. This not only increases the risk of mutual interference between cables but also brings great inconvenience to subsequent maintenance and repair work. Utility Model Content

[0004] The purpose of this application is to provide a marine cable tray that can solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution: On one hand, a marine cable tray is provided, comprising: two crossbeams, multiple support members, multiple supporting members, and multiple reinforcing members. The two crossbeams are arranged at intervals, and the multiple support members are spaced apart between the two crossbeams along the length direction of the crossbeams. Each support member has a support surface for supporting cables, and the support surface is arc-shaped. The multiple supporting members are divided into two rows and are installed at intervals on the side of each crossbeam. The two rows of supporting members are arranged in a one-to-one correspondence. The reinforcing members are connected to the lower part of the support members and the supporting members.

[0006] Furthermore, the plurality of the support members are integrally formed with the two crossbeams.

[0007] Furthermore, the crossbeam is detachably mounted to the support member by fasteners.

[0008] Furthermore, it also includes multiple tray assemblies disposed on the top of the support members arranged in pairs opposite each other, the tray assemblies being used to pull out signal lines.

[0009] Furthermore, the tray assembly includes a connecting plate connected to the top of the two opposing support members, and arc-shaped plates disposed at both ends of the connecting plate, with an accommodating space formed between the arc-shaped plates and the connecting plate for pulling and releasing the signal line.

[0010] Furthermore, the connecting plate and the arc-shaped plate are integrally formed.

[0011] Furthermore, the pallet assembly is a plastic part.

[0012] Furthermore, both the support member and the crossbeam are coated with a first galvanized layer, the thickness of which is 32μm to 40μm.

[0013] Furthermore, both the connecting plate and the arc plate are coated with a second zinc plating layer, the thickness of which is 15μm to 23μm.

[0014] Furthermore, all of the aforementioned support components and the two aforementioned crossbeams are made of plastic.

[0015] The beneficial effects of this application are as follows: The arc-shaped support surface design, by making full use of height space, allows for the placement of more cables within a limited space, effectively solving the problem of low cable capacity in single-layer brackets and meeting the needs of increasingly complex marine electrical systems and a growing number of cables. Simultaneously, this design also makes cable placement more stable, reducing cable swaying and displacement on the bracket, lowering the risk of cable damage due to friction or collision, and ensuring cable lifespan and electrical performance. Furthermore, the rational combination of support and reinforcement components enhances the structural strength and stability of the entire bracket. Compared to multi-layer brackets, the bracket structure of this application is more compact, does not excessively occupy internal ship space, contributes to the rationality and compactness of the overall ship layout, and reserves ample space for the installation of other equipment and systems.

[0019] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] like Figure 1 and Figure 2 As shown, this embodiment provides a marine cable tray, including: two crossbeams 1, multiple support members 2, multiple supporting members 3, and multiple reinforcing members 4. The two crossbeams 1 are arranged at intervals. The multiple support members 2 are arranged at intervals between the two crossbeams 1 along the length direction of the crossbeams 1. The support member 2 has a support surface for supporting cables. The support surface is arc-shaped. The multiple supporting members 3 are divided into two rows and are installed at intervals on the side of each crossbeam 1. The two rows of supporting members 3 are arranged in a one-to-one correspondence. The reinforcing members 4 are connected to the lower part of the support member 2 and the supporting member 3.

[0023] Based on the above scheme, two crossbeams 1 are arranged at intervals to construct a stable frame system for the entire bracket. Multiple support members 2 are arranged at intervals between the two crossbeams 1 along their length, with the key feature being the arc-shaped design of the support surface. This arc-shaped design cleverly utilizes the height space; within a limited height range, compared to a flat support structure, the arc shape better conforms to the natural curvature of the cables, allowing the cables to be placed more compactly, thus accommodating more cables in the same space. Multiple support members 3 are arranged in two rows, installed at intervals on the sides of each crossbeam 1, providing uniform and stable support points for the support members 2, ensuring that the support members 2 will not deform or tilt when bearing the weight of the cables. Reinforcing members 4 connect the lower part of the support members 2 to the support members 3, further strengthening the connection between the support members 2 and the support members 3, effectively distributing the weight of the cables borne by the support members 2 to the support members 3 and the crossbeams 1, making the entire bracket structure more stable and reliable.

[0024] The marine cable tray provided in this application exhibits several outstanding advantages. In terms of space utilization, the arc-shaped support surface design is a major highlight. It cleverly taps into the potential of vertical space, breaking through the limitations of traditional planar support structures in terms of space utilization. Given the extremely limited space inside ships, this design allows for the accommodation of more cables within the same height range, significantly increasing cable capacity and perfectly solving the problem of insufficient cable capacity caused by space constraints in single-layer trays. It provides a practical solution for the ever-increasing cable laying needs of marine electrical systems.

[0025] For the cable itself, the arc-shaped support surface closely matches the cable's natural bending shape, providing a more snug and stable support. This not only reduces cable swaying and displacement on the bracket, preventing damage caused by mutual friction or collision between cables and extending their service life, but also ensures the stability of the cable's electrical performance, guaranteeing the reliable operation of the ship's electrical system.

[0026] From the perspective of the overall structure of the bracket, the rational layout and coordination of the support members 3 and the reinforcing members 4 construct a stable and reliable structural system. The support members 3 are installed in two rows, spaced apart and corresponding one-to-one, on the side of the crossbeam 1, providing uniform and strong support for the support member 2. The reinforcing members 4 further strengthen the connection between the support member 2 and the support members 3, ensuring the entire bracket remains stable under the weight of the cables and is less prone to deformation or damage. Compared to multi-layer brackets, the bracket structure of this application is more compact, occupies less space, helps optimize the internal space layout of the ship, frees up more space for the installation of other equipment and systems, and improves the overall space utilization of the ship.

[0027] Furthermore, the stable bracket structure greatly facilitates cable laying, maintenance, and repair. Operators can more easily arrange and adjust cables, and locate and operate them more quickly during maintenance and repair, significantly improving work efficiency, reducing labor and time costs, and also minimizing potential safety hazards caused by inconvenient operation.

[0028] Furthermore, the multiple support components 2 and the two crossbeams 1 are integrally formed. During manufacturing, a specific process allows them to be molded into a single unit in one go, eliminating connection gaps and weak points that may occur with traditional assembly. This ensures that all parts of the bracket are tightly connected and form a cohesive whole. This design allows for more even distribution of stress when the bracket bears the weight of the cables and external forces, greatly enhancing the stability and reliability of the overall structure. It effectively prevents deformation and breakage during use, extending the bracket's service life. Moreover, the integral molding eliminates cumbersome assembly steps, saving installation time and labor costs, improving installation efficiency. Simultaneously, the absence of assembly errors results in higher installation precision, better ensuring the accuracy and stability of cable laying. In addition, the reduction in the number of components also reduces material waste and assembly costs, improving the product's cost-effectiveness and providing a higher-quality and more economical cable bracket option for marine electrical system construction.

[0029] Furthermore, the crossbeam 1 is detachably mounted to the support member 3 using fasteners 6. The fasteners 6 (such as bolts, nuts, etc.) have a specific structure and threads. During installation, the crossbeam 1 is placed at the corresponding position on the support member 3, aligning the mounting holes on the crossbeam 1 and the support member 3. Then, the fasteners 6 pass through these mounting holes, and the threads secure the crossbeam 1 to the support member 3. When disassembly is required, simply loosen the fasteners 6 to remove the crossbeam 1 from the support member 3, achieving separation of the crossbeam 1 from the support member 3. During installation, this detachable structure makes the installation process of the crossbeam 1 and the support member 3 more flexible and convenient. Construction personnel can easily adjust the position and angle of the crossbeam 1 according to the actual installation environment and needs, ensuring the accuracy and stability of the bracket installation and improving installation efficiency. The advantages of the detachable design are also evident during maintenance and repair. When the bracket is damaged or the cable needs to be replaced, there is no need for a large-scale disassembly of the entire bracket. Simply loosen the fasteners 6 and remove the crossbeam 1 from the support 3 to repair or replace the damaged part, or easily manipulate the cable. This greatly reduces maintenance difficulty and cost, and shortens maintenance time. At the same time, this design also facilitates the transportation and storage of the bracket. During transportation, the crossbeam 1 and support 3 can be packaged separately to save space; during storage, they can be flexibly arranged according to site conditions, improving space utilization.

[0030] In some embodiments, the system further includes multiple tray assemblies 5 disposed on top of the support members 3 arranged in pairs opposite each other. The tray assemblies 5 are used for laying signal cables. The pairs of opposite support members 3 provide a stable mounting base for the tray assemblies 5, which are then installed on top of the support members 3 using specific connection structures (such as slots, bolt fixing, etc.). Signal cables are typically thinner and more flexible than power cables. Providing separate tray assemblies 5 for laying signal cables offers an independent and suitable laying space, preventing signal cables from being mixed with power cables and reducing electromagnetic interference. From a cable management perspective, this effectively separates signal cables from power cables, making the cable layout in the ship's electrical system clearer and more orderly. This facilitates later cable identification, maintenance, and repair, improving work efficiency and reducing the risk of misoperation due to cable clutter. In terms of signal transmission quality, the independent tray assembly 5 creates a relatively independent laying environment for the signal line, effectively reducing the impact of electromagnetic interference generated by power cables on the signal line, ensuring the stability and accuracy of signal transmission, which is crucial for the normal operation of equipment on ships that rely on precise signal transmission (such as navigation systems, communication systems, etc.).

[0031] Specifically, the tray assembly 5 includes a connecting plate 501 connected to the top of two opposing support members 3, and arc-shaped plates 502 disposed at both ends of the connecting plate 501. The arc-shaped plates 502 and the connecting plate 501 form a space for the signal cable to be pulled out. The connecting plate 501 is fixed to the top of the two opposing support members 3 by a specific connection method (such as bolt connection, welding, etc., which, based on the aforementioned detachable design, is more likely a bolt connection for flexible adjustment), providing a stable installation foundation for the entire tray assembly 5. The arc-shaped plates 502 are disposed at both ends of the connecting plate 501, forming a specific space together with the connecting plate 501. Since signal cables typically have a certain degree of flexibility and bendability, the arc design of the arc-shaped plates 502 can conform to the natural curvature of the signal cable. When the signal cable is placed in the space, the arc-shaped plates 502 and the connecting plates 501 can support and limit the signal cable, preventing it from scattering or making unnecessary contact with other objects.

[0032] The connecting plate 501 and the arc-shaped plate 502 are integrally formed. During manufacturing, integral forming processes such as injection molding and die casting are employed. Through specific mold design, the connecting plate 501 and the arc-shaped plate 502 are simultaneously formed into a single unit in the same process. This process utilizes the fluidity and plasticity of the material to complete the construction of the connecting plate 501 and the arc-shaped plate 502 in one step within the mold. There are no connection gaps or weak points between them as in traditional assembly methods; the materials are continuous and tightly bonded.

[0033] As an optional specific implementation, the pallet assembly 5 is a plastic part. Plastic materials have good plasticity and moldability. During manufacturing, molten plastic raw material is injected into a specific mold using injection molding. The mold is designed according to the shape of the pallet assembly 5 (including the connecting plate 501, the arc plate 502, and the accommodating space they form). Under the constraint of the mold, the plastic raw material cools and solidifies to form the pallet assembly 5 that meets the design requirements. This manufacturing method can accurately replicate the shape of the mold, ensuring the dimensional accuracy and shape consistency of the pallet assembly 5. The relatively low density of the plastic material makes the overall weight of the pallet assembly 5 lighter. In a marine environment, reducing the weight of the pallet system helps reduce the overall load on the ship, improves fuel economy and navigation performance, and also facilitates installation and handling.

[0034] Generally, both the support component 2 and the crossbeam 1 are coated with a first zinc plating layer, the thickness of which is 32μm to 40μm. Electroplating utilizes the principle of electrolysis, placing the support component 2 and the crossbeam 1 as cathodes in an electrolyte containing zinc ions. Under the action of direct current, zinc ions gain electrons on the surface of the support component 2 and the crossbeam 1, reducing them to zinc atoms, and gradually depositing to form a uniform zinc plating layer. Hot-dip galvanizing involves immersing the support component 2 and the crossbeam 1 in molten zinc. Through the diffusion reaction between the zinc liquid and the iron substrate, a zinc-iron alloy layer is formed on the surface, followed by a pure zinc layer, ultimately forming a zinc plating layer of a certain thickness. By precisely controlling the process parameters of electroplating or hot-dip galvanizing, such as current density, plating solution composition, immersion time, and temperature, the thickness of the first zinc plating layer can be controlled within the range of 32μm to 40μm.

[0035] In terms of corrosion resistance, zinc is chemically more reactive than iron. In the humid marine environment, when there are minor damages to the galvanized layer surface, zinc will act as a sacrificial anode and be preferentially corroded, thus protecting the iron substrate of the support component 2 and the crossbeam 1 from corrosion and greatly extending the service life of the bracket. The thickness range of 32μm to 40μm ensures sufficient zinc to provide long-term corrosion protection while avoiding increased costs and potential coating brittleness caused by excessively thick coatings.

[0036] From an aesthetic perspective, the galvanized layer gives the surfaces of the support component 2 and the crossbeam 1 a uniform, bright metallic luster, enhancing the overall appearance of the bracket and harmonizing with other equipment and decorations inside the ship. Furthermore, this galvanized layer has excellent adhesion and wear resistance, making it less prone to peeling or wear during daily use and installation, thus maintaining its anti-corrosion and aesthetic properties for a long time.

[0037] Simultaneously, both the connecting plate 501 and the arc-shaped plate 502 are coated with a second galvanized layer, the thickness of which is 15μm to 23μm. This second galvanized layer provides reliable protection for the connecting plate 501 and the arc-shaped plate 502. The reactivity of zinc causes it to corrode preferentially when the coating has minor damage, thus protecting the base material and effectively extending the service life of the pallet assembly 5. The thickness of 15μm to 23μm ensures sufficient zinc to resist corrosion while avoiding problems such as increased cost and brittleness caused by excessively thick coatings.

[0038] Optionally, all of the aforementioned support members 2 and two crossbeams 1 are made of plastic. The density of plastic materials is much lower than that of metal materials, which significantly reduces the weight of the entire bracket system. In a marine environment, weight reduction helps reduce the overall load on the vessel, improving fuel economy and navigation performance. It also facilitates installation and handling, reducing labor costs and equipment burden during installation. Furthermore, from an insulation perspective, plastic components have excellent insulation properties, effectively preventing electrical short circuits or leakage between cables and brackets, as well as between different cables, ensuring the safe operation of the ship's electrical system. This is crucial for the numerous devices on board that rely on power and signal transmission, preventing safety accidents and equipment damage caused by electrical faults.
