Description

Technical Field

[0001] This application relates to the field of cable tray technology, and more specifically to a cable tray structure that facilitates cable replacement. Background Technology

[0002] In the power, telecommunications, and construction industries, cable trays are widely used in various scenarios such as basements, cable trenches, and factories as key equipment for cable laying and protection. Their main function is to provide orderly storage space for cables, protect them from external mechanical damage, dust contamination, and environmental corrosion, and facilitate cable laying, inspection, maintenance, and fireproofing. However, existing cable trays still have many problems in practical applications, including: traditional cable trays are inconvenient to install and often use a top-opening design. Cable installation, replacement, and maintenance operations must be performed from the top of the tray, requiring sufficient operating space above it. In environments with limited height, such as basements and cable trenches, the top-opening design significantly increases the space occupied by the trays, leading to stringent environmental height requirements, space shortages, increased construction difficulty, and reduced efficiency in cable replacement and maintenance. Furthermore, with cables piled up in traditional trays, damaged cables are difficult to remove and replace. Therefore, according to regulations, sufficient margin is usually required to replenish replacement cables, resulting in waste of space and cost. Summary of the Invention

[0003] This application provides a cable tray structure that facilitates cable replacement. This cable tray structure reduces the space occupied by the upper and lower layers, reduces installation difficulty, and effectively prevents cables from tangling and crossing, thus promoting cable heat dissipation.

[0004] The cable tray structure for easy cable replacement provided in this application includes: a cable tray device, the cable tray device including a central support and multiple cable storage trays, the side wall of the central support having multiple interfaces, and the multiple cable storage trays being connected to the central support through corresponding interfaces; the central support and the cable storage trays are each provided with a downward opening on their side walls, and the central support and the cable storage trays are each hinged with a cover plate at the position of their downward openings, the cover plate being able to open and close the downward openings; the central support is provided with a cable layering component at the position of the interface, the cable layering component being used to layer the passing cables; The mounting brackets are multiple in number, and each of the multiple mounting brackets is connected to the cable tray for mounting the cable tray.

[0005] In addition, the cable tray structure for easy cable replacement provided in this application may also have the following additional technical features: In one optional embodiment, the cable layering assembly includes a first receiving plate, a cable layering frame, and friction sleeves; the first receiving plate is arranged opposite to each other on two side walls of the interface; the number of cable layering frames and friction sleeves are both multiple; the multiple cable layering frames are arranged at intervals and rotatably connected to the cable layering frames on both sides of the cable layering frame; the multiple friction sleeves are respectively disposed at the hinge points of the first receiving plate and the cable layering frame, and are used to increase the friction between the two.

[0006] In one alternative embodiment, the cable layer rack includes a rotating plate, a rotating shaft, and a sealing gasket. The rotating shaft is disposed on two side walls of the rotating plate along its length direction. The rotating plate is rotatably connected to the first receiving plate via the rotating shaft. The sealing gasket is disposed on at least one side wall of the rotating plate along its width direction.

[0007] In one alternative embodiment, a plurality of fastening plates are spaced apart on one side wall of the lower opening, and a plurality of second receiving plates are spaced apart on the side wall of the cover plate. The second receiving plates can be fastened to the fastening plates to close the lower opening.

[0008] In one alternative embodiment, the cable tray is provided with multiple cable supports at intervals, the multiple cable supports are arranged at intervals along the height direction of the cable tray, and the cable supports are detachably connected to the cable tray by screws.

[0009] In one alternative embodiment, the cable tray is provided with multiple desiccant holders, which are spaced apart along the length of the cable tray. Each desiccant holder has a preset height and its wall surface is provided with multiple through holes at intervals.

[0010] In one alternative embodiment, the mounting bracket includes a hanger and a support plate, the support plate being connected to the cable tray, and the hanger being integrally formed with the support plate and used to install the hanger in a basement or cable trench.

[0021] like Figure 1-7 As shown, this application embodiment provides a cable tray structure that facilitates cable replacement. This cable tray structure mainly includes a cable tray device 1 and mounting brackets 2. The cable tray device 1 includes a central support 11 and multiple cable storage trays 12. The side wall of the central support 11 has multiple interfaces 111, and the multiple cable storage trays 12 are connected to the central support 11 through corresponding interfaces 111. Both the central support 11 and the cable storage trays 12 have downward openings 13 on their side walls, and each has a cover plate 14 hinged to its downward opening 13, allowing the openings to be opened and closed. The central support 11 has a cable layering component 15 at the interface 111, used to layer the passing cables. Multiple mounting brackets 2 are connected to the cable storage trays 12 for installation.

[0022] Specifically, multiple mounting brackets 2 are provided and installed inside basements or cable trenches. Two types of mounting brackets 2 are provided to adapt to basement and cable trench environments respectively, ensuring stable installation of the cable tray system in different scenarios. Multiple cable tray devices 1 are provided and installed on multiple mounting brackets 2 for cable storage. The cable tray device 1 includes a cable storage tray 12, a central support 11, and a cable layering assembly 15. The cable storage tray 12 is installed on the mounting brackets 2 and has dustproof and waterproof functions to protect cables from external environmental influences. The central support 11 is used to splice multiple cable storage trays 12 together to enhance the overall structural stability. The cable layering assembly 15 is installed at the connection between the central support 11 and the cable storage tray 12 (at the interface 111), dividing the cables into multiple layers arranged vertically for easy management and maintenance later.

[0023] In this embodiment, the cable layering assembly 15 can be implemented using several existing structures; for example, a plate can be used, with holes for guiding and allowing cables to pass through, so that the cables can be passed through during installation to achieve cable layering; similarly, the cable layering assembly 15 can also use the rotary clamping frame described below, so that the cables can be inserted into the clamping frame during installation and layered; as can be seen from the above, the cable layering assembly 15 can be implemented using several existing technologies, so it will not be elaborated further in this article.

[0024] The working principle of this embodiment is as follows: Install the mounting bracket 2 inside the basement, then splice the cable storage tray 12 together through the central support member 11, and then install it on the mounting bracket 2 with bolts. Then open the cover plate 14, then pass the cable through the cable storage tray 12 and the central support member 11, and layer and clamp it through the cable layering component 15. Then close the cover plate 14.

[0025] The cable tray structure features downward openings 13 on the side walls of both the central support component 11 and the cable storage tray 12. These openings can be opened via a cover plate 14, facilitating cable installation and replacement, reducing installation difficulty, and saving space between upper and lower levels, thereby reducing the height of the basement or the depth of the cable trench. The cable layering component 15 allows for layered cable arrangement, preventing cable tangling and crossover, improving heat dissipation, and facilitating later identification and maintenance in conjunction with the cover plate 14. Furthermore, the side wall of the central support component 11 has multiple interfaces 111, allowing for the flexible splicing of multiple cable storage trays 12 according to actual laying requirements, thus better adapting to different laying paths and lengths.

[0026] It should be further noted that, in this embodiment, the central receiving member 11 has interfaces 111 on all four sides, and the lower opening 13 of the central receiving member 11 is located between two adjacent interfaces 111. The interfaces 111 ensure the stability and durability of the connection between the central receiving member 11 and the cable tray 12. Each interface 111 can be designed with anti-slip texture and sealing ring, and the interface 111 is equipped with a locking structure (such as the cooperation of a slot and a snap-fit ​​structure), making the installation and disassembly process more convenient and efficient. In addition, the lower opening 13 is designed to facilitate the quick installation and removal of the cover plate 14, thereby simplifying the maintenance process. It also allows cables to be pulled out and put in for maintenance from the side, so that the device does not need to leave space at the top for cable pulling out and putting in.

[0027] like Figure 3-4 As shown, in one specific embodiment, the cable layering assembly 15 includes a first receiving plate 151, a cable layering frame 152, and a friction sleeve 153. The first receiving plate 151 is arranged opposite to the two side walls of the interface 111. The number of cable layering frames 152 and friction sleeves 153 are multiple. The multiple cable layering frames 152 are arranged at intervals and rotatably connected to the cable layering frames 152 on both sides of the cable layering frame 152. The multiple friction sleeves 153 are respectively disposed at the hinge of the first receiving plate 151 and the cable layering frame 152, and are used to increase the friction between the two.

[0028] Specifically, there are two first receiving plates 151, which are installed on both sides of the central receiving member 11 at the interface 111 position to support and fix the cable layer rack 152; there are multiple cable layer racks 152, which are rotatably installed between the two first receiving plates 151 to clamp and fix the cables and ensure the stability and safety of the cables; the friction sleeve 153 is installed at the hinge between the first receiving plate 151 and the cable layer rack 152 to increase the friction during rotation and prevent the cable layer rack 152 from rotating under the action of external force.

[0029] The working principle of this embodiment is as follows: When in use, rotate the cable layer rack 152 to a horizontal state and pass the cable through the cable layer rack 152 for fixation. When the cable layer rack 152 is not in use, rotate the cable layer rack 152 to a vertical state and block the opening of the central receiving member 11 to prevent external impurities from entering the interior of the central receiving member 11 and affecting the service life of the cable.

[0030] like Figure 5As shown, in one specific embodiment, the cable layer rack 152 includes a rotating plate 154, a rotating shaft 155, and a sealing gasket 156. The rotating shaft 155 is disposed on two side walls of the rotating plate 154 along the length direction. The rotating plate 154 is rotatably connected to the first receiving plate 151 through the rotating shaft 155. The sealing gasket 156 is disposed on at least one side wall of the rotating plate 154 along the width direction.

[0031] In this embodiment, the cable layer rack 152 includes a rotating plate 154, a rotating shaft 155, and a sealing gasket 156. The rotating plate 154 serves as the basic component for support and rotation. Two rotating shafts 155 are provided, which are fixedly installed at both ends of the rotating plate 154 and inserted into the interior of the first receiving plate 151 to connect with the friction sleeve 153. The two rotating shafts 155 enable the rotating plate 154 to rotate freely within the first receiving plate 151. The insertion of the rotating shafts 155 into the interior of the first receiving plate 151 and their connection with the friction sleeve 153 increases the friction force during rotation, ensuring stability and reliability. A sealing gasket 156 is bonded to the outside of the rotating plate 154. When the cable is pulled out, the central receiving component 11 is closed. After the cable is pulled out, the sealing gasket 156 can effectively prevent dust, moisture, and other impurities from entering the equipment, protecting key components from damage, thereby better ensuring the safety and stability of the equipment.

[0032] like Figure 3-4 As shown, in one specific embodiment, a plurality of fastening plates 16 are spaced apart on one side wall of the lower opening 13, and a plurality of second receiving plates 17 are spaced apart on the side wall of the cover plate 14. The second receiving plates 17 can be fastened to the fastening plates 16 to close the lower opening 13. The fastening plates 16 and the second receiving plates 17 ensure the stability of the cover plate 14 when closed, preventing the cover plate 14 from being rotated open during use.

[0033] like Figure 6-7 As shown, in one specific embodiment, a plurality of cable supports 121 are spaced apart inside the cable tray 12. The cable supports 121 are arranged at intervals along the height direction of the cable tray 12, and the cable supports 121 are detachably connected to the cable tray 12 by screws 123. The cable supports 121 are used to support and fix the cables, ensuring that they are neatly arranged inside the tray. The ends of the cable supports 121 are fixedly installed with screws 123 that pass through the cable tray 12. The screws 123 enhance the stability of the entire structure and prevent the cable supports 121 from moving or falling off due to external forces.

[0034] like Figure 1-4As shown, in one specific embodiment, the cable tray 12 is provided with multiple desiccant holders 124. These holders are spaced apart along the length of the cable tray 12, each with a preset height and multiple through holes 125 spaced apart on its wall surface. The desiccant holders 124 ensure the stability and reliability of the desiccant during long-term use. The through holes 125 on the desiccant holders 124 allow for air circulation, improving the drying effect.

[0035] like Figure 6-7 As shown, in one specific embodiment, the mounting bracket 2 includes a hanger 21 and a support plate 22. The support plate 22 is connected to the cable tray 12. The hanger 21 and the support plate 22 are integrally formed and used to install the hanger 21 in a basement or inside a cable trench. Specifically, the hanger 21 is installed on the basement ceiling or embedded in the cable trench to support the entire bracket system and ensure its stability. The support plate 22 is integrally formed with the hanger 21, and the cable tray 12 is placed on the support plate 22 to bear the weight of the cable tray 12 and its internal cables, while providing additional protection against physical damage or interference to the cables.

[0036] The working principle of the cable tray structure provided in this application is as follows: The mounting bracket 2 is installed inside the basement. The cable storage tray 12 is assembled together via the central connector 11 and then placed on the mounting bracket 2. The cable bracket 121 is then installed inside the cable storage tray 12 via screws 123. The cover plate 14 is then opened, and the rotating plate 154 is rotated to a horizontal position. The cable is then passed through the space above the rotating plate 154 and the cable bracket 121. Finally, the cover plate 14 is closed. When not in use, the rotating plate 154 is rotated to a vertical position, and the opening of the central connector 11 is blocked to prevent external impurities from entering the interior of the central connector 11 and affecting the cable's lifespan.

[0037] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
