Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and more specifically, to a ground-mounted cable tray. Background Technology

[0002] Cable trays, as a type of bridge structure used for installing and supporting cables, are typically made of metal or non-metal materials and include components such as crossbeams, longitudinal beams, and connectors. They can be flexibly installed on walls, ceilings, and even floors to achieve the orderly laying and management of cables. Cable trays play an important role in protecting and managing cables.

[0003] In specific environments such as industrial plants, ground-mounted cable trays face even more severe challenges due to their unique installation characteristics. Currently, even cable trays laid on the ground in industrial plants using materials with a certain degree of strength, such as stainless steel or PVC, are prone to damage and deformation after being subjected to frequent foot traffic or the crushing force of small equipment. This is because their structural design is not adequately adapted to the complex stress conditions of the ground. The main reason for this is the inadequate structural design of existing ground-mounted cable trays. For example, their load-bearing structure fails to effectively distribute and resist dynamic impact forces from above, or they lack sufficient reinforcement in critical stress areas. As a result, under repeated foot traffic, the cable tray itself is prone to structural damage, permanent deformation, or loosening of connections. Such damage not only directly threatens the safety of the cables inside the tray, potentially causing cable compression, wear, or even breakage, leading to electrical faults or safety accidents, but also incurs additional time and economic costs for repairing and replacing damaged cable trays, and may even disrupt normal production operations. In application scenarios with high pedestrian traffic and frequent foot traffic, even if the cable tray material itself is qualified, an unreasonable structural design can cause the cable tray to prematurely fail due to long-term cyclic loads and stress concentration.

[0004] Therefore, how to provide a ground-mounted cable tray with a more reasonable structural design that can effectively resist the pressure of being stepped on and is not easily deformed or damaged, so as to ensure the safety of personnel walking and the effective management of cables, has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The purpose of this utility model is to provide a ground-mounted cable tray with a more reasonable structural design that can effectively resist the pressure of being stepped on from the ground, is not easily deformed or damaged, and thus ensures the safety of personnel walking and the effective management of cables.

[0006] This utility model provides a ground-mounted cable tray, including a trough and a cover plate detachably installed on the top of the trough. Inside the trough, a cable separator plate extending along the length of the trough for separating cables is also fixedly connected. Multiple reinforcing supports are fixedly connected to the bottom plate of the trough. The multiple reinforcing supports are spaced apart along the length of the trough and staggered in the width of the trough. The reinforcing supports are supported on the bottom of the cover plate. The top surface of the cover plate is provided with an anti-slip structure.

[0007] Optionally, the reinforcing support is a plate-shaped structure, installed perpendicular to the bottom plate of the tank, and at least one side of the reinforcing support has a reinforcing rib.

[0008] Optionally, multiple reinforcing supports are distributed in multiple rows within the tank, with each row of reinforcing supports extending along the length of the tank, and the reinforcing supports in adjacent rows being staggered along the length of the tank.

[0009] Optionally, the anti-slip structure includes an anti-slip texture provided on the top surface of the cover plate and / or an anti-slip coating applied to the top surface of the cover plate.

[0010] Optionally, the anti-slip texture is a diamond embossed pattern.

[0011] Optionally, a cover plate reinforcement structure is fixedly connected to the bottom surface of the cover plate.

[0012] Optionally, the cover plate reinforcement structure includes multiple reinforcing ribs fixed to the bottom surface of the cover plate.

[0013] Optionally, the reinforcing rib is a U-shaped reinforcing rib.

[0014] Optionally, the tank includes a bottom plate and two risers extending upward from both sides of the bottom plate. The upper edges of the two risers each have an inwardly bent edge parallel to the bottom plate, and the inwardly bent edge is supported on the bottom of the cover plate.

[0015] Optionally, the two sides of the cover plate are bent downward to form guide edges, which are located on the outer side of the two sides of the groove and are matched with it for positioning.

[0016] Based on the technical content disclosed in this utility model, the following beneficial effects are achieved:

[0017] This utility model provides a ground-mounted cable tray that optimizes the internal load-bearing structure of the trough by arranging multiple reinforcing supports at intervals along its length and staggered in its width. This effectively disperses the pressure applied to the cable tray by foot traffic to multiple support points and transmits it to the sidewalls and bottom of the trough, significantly enhancing the overall structural strength and deformation resistance of the trough against external foot traffic. This effectively solves the technical problem of existing ground-mounted cable trays being prone to damage and deformation after being stepped on due to unreasonable structures. Simultaneously, the anti-slip structure on the top surface of the cover plate directly increases the friction when personnel walk on the cable tray surface, reducing the risk of slipping due to a wet cover surface and enhancing operational safety. The cable separators extending along the length of the trough inside achieve orderly separation and management of internal cables, preventing tangled cables and facilitating wiring and subsequent maintenance. Through its reasonable structural design, this utility model makes the ground-mounted cable tray more stable and durable under foot traffic, safer and more convenient to use, effectively protecting the internal cables and extending the service life of the cable tray itself.

[0024] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0025] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0027] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0029] The present invention provides a ground-mounted cable tray whose overall concept lies in strengthening the internal structure of the trough and the structure of the cover plate itself, providing the cover plate surface with anti-slip function, and optimizing cable management inside the trough, so that it can adapt to complex working conditions such as personnel trampling or light equipment running over it when laid on the ground. The cable tray mainly consists of three parts: a trough with an internally reinforced structure, cable separators for separating cables, and a cover plate with anti-slip and reinforced structures.

[0030] Reference Figures 1 to 3 The ground-mounted cable tray includes a trough 1, a cover plate 2 detachably mounted on top of the trough 1, a cable divider plate 4 fixedly connected inside the trough 1, and multiple reinforcing supports 3.

[0031] The tank body 1 is preferably made of high-strength and corrosion-resistant stainless steel (e.g., SUS304 or SUS316L). Figure 1As shown, the trough 1 includes a base plate 12 and two Nippon 13s extending upward from both sides of the base plate 12. Each of the two Nippon 13s has an integrally formed inner flange 11 that bends inward into the trough. This inner flange 11 is approximately parallel to the base plate 12 of the trough 1 and serves to support the cover plate 2 and enhance the structural strength at the opening of the trough. Specific design of the cross-sectional dimensions of the trough 1 optimizes its foundation bearing capacity and structural stability against deformation while ensuring material economy. For example, the design ratio of the width of the trough 1 to the height of the Nippon 13 can be (1.8-2.2):1, and the ratio of the width of the trough 1 to the thickness of its plates can be (90-110):1. This specific dimensional design ensures that when the trough 1 is subjected to a linear load, for example, not exceeding 5 kN / m, the deformation can be effectively controlled within a predetermined range, for example, 0.15%, thus providing a solid structural foundation for the long-term stable use of the entire cable tray under complex working conditions such as ground trampling. Under dynamic load conditions, it is recommended to take the lower limit of the range (e.g., width: side plate height is 1.8:1, width: plate thickness is 90:1), and under static load conditions, the midpoint of the range can be taken (e.g., width: side plate height is 2:1, width: plate thickness is 100:1) to ensure that, for example, when subjected to a load of ≤5kN / m, the deformation is controlled within 0.15%.

[0032] Multiple reinforcing support members 3 are fixedly connected inside the tank 1. These reinforcing support members 3 are spaced apart along the length of the tank 1 and staggered along the width of the tank 1. Figure 1 and Figure 3As shown, the reinforcing support 3 is a plate-like structure. After installation, its plate surface is approximately perpendicular to the bottom plate 12 of the tank 1 and parallel to the Nippon 13 of the tank 1. Each reinforcing support 3 has one or more reinforcing ribs 31 on at least one or both sides of its plate-like structure to improve its rigidity and bending resistance. In a preferred embodiment, the reinforcing support 3 is designed as a 10cm long plate with X-shaped stamped reinforcing ribs evenly spaced on it. The length or width of the X-shaped stamped reinforcing ribs can be 5cm to further enhance its bending modulus. These reinforcing supports 3 are arranged in a diagonally staggered layout, for example, they can be distributed in multiple rows, which extend approximately along the length direction of the tank 1, and the reinforcing supports 3 in adjacent rows are staggered along the length direction of the tank 1. In a preferred embodiment, the first direction is defined as extending along the width of the groove, and the second direction is defined as extending along the length of the groove. In the first direction, the spacing between two adjacent reinforcing support members 3 is set to (0.4-0.75):1 of the groove width; in the second direction, the spacing between two adjacent reinforcing support members 3 is set to (0.2-0.4):1 of the groove length. In this application, the groove width is 200mm. The spacing between two adjacent reinforcing support members 3 in the first direction can be controlled within the range of 80-150mm, and the spacing between two adjacent reinforcing support members 3 in the second direction can be set to 300-600mm. For example, when using a 100mm transverse spacing and a 450mm longitudinal spacing, at 1200kg / m²... 2 Under load, the maximum stress of the cable tray can be controlled within the allowable stress range (e.g., 83MPa < allowable stress 215MPa), and the displacement can be controlled within the permissible range (e.g., 0.38mm < L / 300 = 1.5mm). This staggered arrangement effectively distributes the concentrated trampling force to more support points and the sidewalls of the trough 1, avoiding stress concentration and thus improving the overall compressive bearing capacity and structural stability of the trough 1. The reinforcing support 3 can be firmly fixed to the inner wall and / or bottom plate 12 of the trough 1 by welding or other methods.

[0033] like Figure 1 As shown, at least one cable divider 4 is also fixedly connected inside the tank 1. The cable divider 4 extends along the length of the tank 1, dividing the interior of the tank 1 into multiple independent wiring channels. Preferably, when only one cable divider 4 is provided, the cable divider 4 divides the interior of the tank 1 into a power line area and a control line area, wherein the width ratio of the two is 6:4, and a reinforcing support is provided in the power line area. The cable divider 4 is, for example, made of 1.5mm thick stainless steel plate (such as SUS304 / 316L) stamped and formed, and its thickness to tank width ratio can be, for example, 1:48. The plate height can be 90% of the total tank height. In a preferred layout, such as... Figure 1As shown, multiple reinforcing support members 3 are arranged on one side of the cable separator plate 4, so that in the two wiring channels separated by the cable separator plate 4, one channel is equipped with a reinforcing support member 3, while the other channel remains intact and unobstructed by support members, thereby forming a wider cable laying space, which is convenient for laying thicker or more cables.

[0034] like Figure 2 and Figure 3 As shown, the cover plate 2 is also preferably made of high-strength stainless steel (e.g., 2mm or 3mm thick SUS304 / 316L) by stamping. The top surface of the cover plate 2 is provided with an anti-slip structure 21. This anti-slip structure 21 can be achieved by stamping an anti-slip texture with a certain depth of relief on the surface of the cover plate 2, such as a diamond-shaped embossing, and / or by spraying a wear-resistant anti-slip coating (e.g., an anti-slip ceramic coating, which can be integrated with the guide channel design) onto the surface of the cover plate 2 to improve its frictional performance (e.g., coefficient of friction μ≥0.75). This design significantly increases the coefficient of friction of the cover plate 2 surface, effectively preventing slippage even when people are walking on it, even in the presence of water or oil.

[0035] The connection between the cover plate 2 and the tank 1 can be made in various detachable ways. In a preferred embodiment, the two sides of the width of the cover plate 2 are bent downward to form guide edges 22. When the cover plate 2 is fastened to the tank 1, the main body of the cover plate 2 is supported on the inner folded edges 11 of the upper edges of the two vertical supports 13 of the tank 1, while the guide edges 22 of the cover plate 2 are located on the outer sides of the two vertical supports 13 of the tank 1, playing a certain guiding and positioning role through clearance fit or interference fit. In order to further ensure the firm fixation and main load-bearing capacity of the cover plate 2, crossbeams (not shown in the figure, the crossbeams extend along the width direction of the cover plate) can be arranged at intervals along the length direction of the tank 1 at the bottom of the cover plate 2 as the main load-bearing points, or the cover plate 2 can be directly fixed to the inner folded edges 11 of the tank 1 or the corresponding position of the top of the reinforcing support 3 through the cover plate 2 itself and by means of anti-loosening bolts. This connection method can not only ensure the stability and load-bearing capacity of the cover plate 2 installation, but also facilitate subsequent opening and maintenance.

[0036] In an optional embodiment, the reinforcing structure of the bottom surface of the cover plate 2 is preferably a plurality of U-shaped reinforcing ribs extending along the width direction of the cover plate 2. The U-shaped reinforcing ribs extend from the free end of the guide edge 22 on one side of the width to the free end of the guide edge 22 on the other side of the width on the bottom surface of the cover plate 2. These U-shaped reinforcing ribs can be fixed to the bottom surface of the cover plate 2 by welding, and their spacing can be designed according to the width of the cover plate and the expected load, for example, a spacing of 120mm. The setting of the U-shaped reinforcing ribs is like adding multiple "keels" under the flat plate, which greatly improves the bending stiffness and load-bearing capacity of the cover plate 2, making it less prone to bending deformation when subjected to single-point or small-range trampling pressure.

[0037] Those skilled in the art should understand that the embodiments of this utility model are not limited to the above description. Any implementation based on the concept of this utility model through simple substitution or modification should fall within the protection scope of this utility model. For example, the cross-sectional shape of the reinforcing support 3, the number and fixing method of the cable separator 4, and the shape and layout of the specific ribs of the cover plate reinforcing structure can all be adjusted according to actual needs.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
