Description

Technical Field

[0001] This utility model relates to the technical field of cable tray protection devices, and in particular to flame-retardant and fireproof cable tray protection devices. Background Technology

[0002] In the field of cable tray protection technology, with the continuous increase in cable lines in modern buildings and industrial facilities, the fire safety of cables is receiving increasing attention. Especially in key areas such as smart cities and new energy, the dense arrangement of cables significantly increases the risk of fire. Once a cable fire occurs, it can not only cause enormous property damage but also seriously threaten the lives of people.

[0003] In existing technologies, such as the fire-resistant cable tray disclosed in CN2179513Y, although the structural design of a metal outer shell and a flame-retardant inner shell improves the fire resistance of the cable to some extent, there are still some shortcomings. For example, this structure mainly relies on the flame-retardant properties of the inner shell, and fails to fully consider the overall fire-resistant sealing of the cable tray and the convenience of installation and maintenance. In addition, there are no effective preventive measures for the potential displacement or detachment of the cable tray in a fire.

[0004] Specifically, existing cable tray protection devices often have limitations in fire resistance. Many cable trays made of non-flame-retardant materials are prone to combustion when exposed to open flames or high temperatures, thus accelerating the spread of fire along the cable lines and expanding the fire's area. Simultaneously, the combustion process may release large amounts of dense smoke and toxic gases, such as hydrogen chloride and carbon monoxide, seriously threatening the safety of personnel escape and fire rescue operations.

[0005] Existing cable tray protection devices also face challenges in terms of structural stability. In extreme situations such as fires, cable trays may shift or detach due to thermal expansion or combustion of materials, leading to cable damage or secondary disasters. This not only increases the difficulty of firefighting but may also severely impact subsequent power supply and facility restoration.

[0006] Furthermore, existing cable tray protection devices present numerous inconveniences during installation and maintenance. For example, some devices require complex installation procedures and specialized tools, increasing construction costs and time. Simultaneously, during subsequent maintenance, the complex structure of the devices makes rapid disassembly and inspection difficult, further reducing the efficiency and safety of the cable trays.

[0007] In summary, existing cable tray protection devices are inadequate in terms of fire resistance, structural stability, and ease of installation and maintenance, making it difficult to meet the high fire safety requirements of modern buildings and industrial facilities. Therefore, it is necessary to develop a new type of flame-retardant and fire-resistant cable tray protection device to solve the above problems and improve the fire safety performance of cables.

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0037] Example 1

[0038] Please see Figures 1 to 4 This embodiment provides a flame-retardant and fireproof cable tray protection device, which specifically includes a cable tray body 1, a round rod 2, a fixing component 3, and a connecting component 4.

[0039] The cable tray body 1 serves as the main structure for carrying cables, and two round rods 2 are installed on its top. The round rods 2 are made of PP flame-retardant material with 30% magnesium hydroxide flame retardant added to improve the overall fire resistance.

[0040] The fixing assembly 3 is located at the top of the round rod 2 and is used to fix the cable tray to the factory ceiling. The fixing assembly 3 includes a base plate 31, a top plate 32, soft pads 34, round pads 36, threaded rods 37, and threaded rings 38. The base plate 31 is close to the bottom of the factory ceiling, and the top plate 32 is provided on its top. Soft pads 34 are connected to one side of both the base plate 31 and the top plate 32 to ensure a tight fit with the ceiling. A round hole 33 is opened in the middle of the top plate 32, and a through groove 35 is opened in the middle of the two soft pads 34. Three threaded rods 37 are evenly connected to the top of the base plate 31. These threaded rods 37 pass through the interior of the corresponding round holes 33 and are connected to the round pads 36 at the bottom end of the soft pads 34 located at the top. A threaded ring 38 is provided at the top of the threaded rod 37, and the inner wall of the threaded ring 38 is threadedly connected to the outer wall of the threaded rod 37.

[0041] During installation, the top of the soft pad 34 on the top of the base plate 31 is aligned with the bottom of the factory ceiling, and the threaded rod 37 passes through the ceiling. Then, the top plate 32 is placed downwards on top of the threaded rod 37. At this point, the bottom of the soft pad 34 at the bottom of the top plate 32 is aligned with the top of the factory ceiling, and the bottom of the round pad 36 is pressed against the top of the factory ceiling. Finally, the threaded ring 38 is placed on top of the threaded rod 37, and the threaded ring 38 is screwed to fix it to the top of the top plate 32, thus completing the installation of the fixing component 3.

[0042] The connecting component 4 is located at the bottom of the round rod 2 and fits tightly against the outer wall of the cable tray body 1. The connecting component 4 includes two retaining frames 41, a block 42, a silicone pad 46, a fixing rod 44, and a fixing ring 45. One end of the retaining frame 41 is connected to the block 42, and the other ends of the two retaining frames 41 are rotatably connected to each other. A through groove 43 is opened in the middle of the block 42, and a silicone pad 46 is placed between the two blocks 42. A through hole 47 is opened in the middle of the silicone pad 46. The fixing rod 44 passes through the corresponding through groove 43 and through hole 47, and a fixing ring 45 is provided at one end of it. The inner wall of the fixing ring 45 is threadedly connected to the outer wall of the fixing rod 44. The inner wall of the retaining frame 41 fits tightly against the outer wall of the cable tray body 1, and the top end of the retaining frame 41 is fixedly connected to the bottom end of the round rod 2.

[0043] When installing the cable tray body 1, rotate the two retaining frames 41 so that their inner walls fit against the outer wall of the cable tray body 1. Then, align the two square blocks 42 connected to one end of the cable tray body 1 with each other, and align the through hole 47 with the through groove 43. Next, insert the fixing rod 44 into the through groove 43, so that it passes through the through hole 47 and the through groove 43. Finally, align the fixing ring 45 with the fixing rod 44, and rotate the fixing ring 45 spirally so that it fits into the middle of the fixing rod 44, thereby completing the installation of the cable tray body 1.

[0044] Example 2

[0045] In another preferred embodiment, based on Embodiment 1, this embodiment has a similar basic structure to Embodiment 1, but differs in specific details. Please refer to... Figures 1 to 4 Especially in the design of connecting component 4.

[0046] In Embodiment 2, the connecting assembly 4 also includes two clip frames 41, a block 42, a silicone pad 46, a fixing rod 44, and a fixing ring 45. However, unlike the previous embodiment, to further improve the stability and fire resistance of the connection, the material of the silicone pad 46 has been optimized in this embodiment. The silicone pad 46 is made of a special material with excellent high-temperature resistance and fire resistance, and its temperature resistance can reach 300°C and above, to ensure that it can continue to provide effective isolation and sealing in the event of a fire.

[0047] Furthermore, in Embodiment 2, we have also improved the soft pad 34 in the fixing assembly 3. The soft pad 34 is made of a material with higher elasticity and sealing performance to further improve the fit and sealing effect with the ceiling. This improvement enables the fixing assembly 3 to better prevent the spread of flames and smoke in the event of a fire, thereby more effectively protecting the cable tray and cables.

[0048] During installation, the steps in Embodiment 2 are basically the same as those in Embodiment 1. First, the fixing component 3 is installed and firmly fixed to the factory ceiling; then, the connecting component 4 is installed to connect the cable tray body 1 to the fixing component 3. Because this embodiment has optimized the selection and improved the design of some materials for the connecting component 4 and the fixing component 3, the entire installation process is smoother and more stable and reliable.

[0049] In a preferred embodiment, the fixing component 3 includes a base plate 31, a top plate 32 is provided on the top of the base plate 31, and soft pads 34 are installed on the upper surface of the base plate 31 and the lower surface of the top plate 32. The above configuration can enhance the stability and buffering performance between the base plate 31 and the top plate 32. At the same time, side plates 33 are also provided around the base plate 31. The side plates 33, the base plate 31 and the top plate 32 together form a closed cavity to further increase the stability of the structure.

[0050] In a preferred embodiment, a set of threaded rods 37 are installed on the upper surface of the base plate 31, and several circular holes 33 are opened at corresponding positions on the top plate 32. A through groove 35 is opened on the soft pad 34. The threaded rods 37 pass through the circular holes 33 and the through groove 35, and the base plate 31 and the top plate 32 are connected as a whole by a threaded ring 38 installed on the upper surface of the top plate 32. This configuration, through the precise alignment and cooperation of the threaded rods 37 with the circular holes 33 and the through groove 35, combined with the locking and fixing of the threaded ring 38, achieves an efficient integrated connection between the base plate 31 and the top plate 32, forming a modular flame-retardant frame. In this structure, the soft pad 34 undergoes elastic deformation under pressure, which can fully fill the installation gap between the cable tray and the ceiling, forming a flexible sealing layer. This not only enhances the fireproof smoke penetration barrier effect but also reduces the impact damage to the cable tray body caused by vibration through multi-directional stress dispersion. Meanwhile, the mechanical engagement design of the threaded rod 37 and the threaded ring 38 can withstand a torque of more than 150 N·m, ensuring structural stability under fire conditions and avoiding connection failure caused by high temperature thermal expansion, thereby systematically improving the safety redundancy of the cable tray system in complex environments.

[0051] In a preferred embodiment, a plurality of round pads 36 are installed at the bottom of the soft pad 34 on the lower plane of the top plate 32. This arrangement allows the soft pad 34 to make closer and more uniform contact with the structure below, effectively dispersing pressure and avoiding damage caused by excessive local pressure. At the same time, the round pads 36 can also increase friction and ensure the stability of the installation.

[0052] In a preferred embodiment, the connecting component 4 includes a set of card frames 41, one end of which is fitted with a set of blocks 42, and the other ends of the card frames 41 are rotatably connected to each other. This arrangement allows the connecting component 4 to be adjusted at an angle as needed during use, while the blocks 42 are used to make stable connections with other components, ensuring the robustness and flexibility of the entire structure.

[0053] In a preferred embodiment, a through groove 43 is provided in the middle of the block 42, and a silicone pad 46 is installed between a group of blocks 42. A through hole 47 is provided in the middle of the silicone pad 46. The fixing rod 44 passes through the through groove 43 and the through hole 47, and a group of card frames 41 are connected as a whole by a fixing ring 45. The above configuration not only enhances the connection stability between the card frames 41, but also provides a certain buffering effect through the silicone pad 46, effectively reducing vibration. At the same time, the cooperation between the fixing rod 44 and the fixing ring 45 makes the overall structure more robust and easy to install and disassemble.

[0054] In the preferred embodiment, the silicone pad 46 is heat resistant to 300℃ and above; the above settings ensure the stability and durability of the silicone pad in high-temperature environments, effectively isolate heat transfer, protect surrounding components from high temperature effects, and improve the overall safety performance and operating efficiency of the equipment.

[0055] In a preferred embodiment, the fixing component 3 is made of flame-retardant PVC material, and the round rod 2 is made of PP + 30% magnesium hydroxide flame retardant material. The above settings effectively improve the high temperature resistance and safety of the overall structure, ensuring stable operation even in complex environments. In addition, the material selection of the round rod 2 also enhances its mechanical strength and extends its service life.

[0056] This utility model proposes a flame-retardant and fireproof cable tray protection device, which effectively overcomes the shortcomings of existing cable trays in the field of cable tray protection technology in terms of fire resistance, ease of installation, structural stability, and safety in the event of a fire.

[0057] This utility model features a unique fixing component structure, which includes a base plate 31, a top plate 32, a soft pad 34, a round pad 36, a threaded rod 37, and a threaded ring 38. Through the cooperation of these components, a stable connection and sealing effect are achieved between the cable tray and the factory ceiling, effectively preventing flame combustion on the top of the cable tray and preventing electrical leakage.

[0058] Regarding the connecting components, this utility model comprises a frame 41, a block 42, a silicone pad 46, a fixing rod 44, and a fixing ring 45. This design enables rapid installation and disassembly of the cable tray, significantly improving the practicality and convenience of the device.

[0059] In terms of material selection, the fixing component 3 is made of flame-retardant PVC material, while the round rod 2 is made of flame-retardant PP material with 30% magnesium hydroxide flame retardant added. This material combination is relatively novel in cable tray protection devices and significantly improves the fire resistance of the device.

[0060] The design of both the fixing component 3 and the connecting component 4 in this utility model reflects a high degree of precision. Through the precise cooperation of components such as the threaded rod 37, the top plate 32, and the bottom plate 31, a stable connection and sealing effect are achieved. Meanwhile, the design of components such as the clip frame 41 and the silicone gasket 46 in the connecting component 4 further enhances its ability to be quickly installed and disassembled.

[0061] In terms of performance optimization, this invention not only focuses on improving fire resistance but also fully considers factors such as ease of installation, structural stability, and safety in the event of a fire. Through comprehensive performance optimization, a good balance and synergistic improvement among these performance characteristics are achieved.

[0062] In summary, this invention creatively improves the fire resistance of cable tray protection devices by combining flame-retardant PVC and PP materials (with added flame retardants). Furthermore, this device offers advantages such as convenient installation, stable structure, and high safety, providing a novel technical solution for the field of cable tray protection.
