Technical Field

[0001] This utility model relates to the technical field of cable laying auxiliary equipment, and in particular to a fire-resistant cable tray for cable trenches. Background Technology

[0002] During cable laying in cable trenches, cable trays are needed to protect and organize the cables. Existing cable trays often have the following shortcomings: they are inconvenient to install and transport; they lack a stable heat insulation and fireproof structure within the tray; cables are easily tangled within the tray, making classification and management difficult; and the splicing of adjacent trays is complex and difficult to adjust flexibly according to the length of the cable trench. Therefore, this paper proposes a cable tray that is easy to install and disassemble, provides stable fire and heat insulation, and facilitates cable classification and splicing, thus addressing the pain points of existing technologies. Utility Model Content

[0003] This utility model provides a fire-resistant cable tray for cable trenches, addressing the technical problems of inconvenient disassembly and assembly of cable trays, easy cable tangling, and cumbersome splicing.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: A fire-resistant cable trough for cable trenches includes a trough body and a cover plate that fits onto the trough body. A detachable part is provided between the cover plate and the trough body. The detachable part includes an elongated slot extending along the length of the trough body's edge and a pressure strip integrally formed on the lower end face of the cover plate. The pressure strip is adapted to the elongated slot and achieves a detachable connection between the cover plate and the trough body through a snap-fit ​​engagement. A float-type heat insulation plate is fixedly installed inside the trough body. When the cover plate is closed, the pressure strip abuts against and presses against the upper surface of the float-type heat insulation plate to restrict its displacement. Multiple connecting parts are provided on the outer walls of both ends of the trough body, and adjacent trough bodies are spliced ​​together through these connecting parts to extend the overall length.

[0005] Furthermore, the connecting part includes slots formed on the outer walls at both ends of the groove, and the slots of adjacent grooves are connected by a connecting plate; a fixing hole is formed in the slot, and a connecting hole is formed on the connecting plate to cooperate with a fastener; the fastener passes through the connecting hole and is connected to the fixing hole to splice and fix the two grooves together.

[0006] Furthermore, the cross-section of the floating bead insulation board is mountain-shaped.

[0007] Furthermore, the cross-section of the floating bead insulation board is wavy.

[0008] Furthermore, the trough and cover plate are made of lightweight insulating rubber.

[0009] Furthermore, the floating bead insulation board is fixed to the tank body with strong adhesive.

[0010] Furthermore, the pressure strip is a magnetic strip, and the long slot is an iron strip.

[0011] Compared with the prior art, this utility model has the following advantages: Lightweight and Insulation Safety: The trough and cover are made of lightweight insulating rubber, which reduces the overall weight, facilitates installation, handling and maintenance, and blocks current conduction, avoiding the risk of electric shock and electric field interference, ensuring stable cable transmission; Convenient and Stable Assembly and Disassembly: The assembly and disassembly parts use magnetic strips (pressure strips) and iron strips (long slots) for magnetic attraction, allowing for quick closing and removal of the cover without complicated operations.

Detailed implementation method: The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1-3As shown, this utility model discloses a fire-resistant cable trough for cable trenches, comprising a trough body 1 and a cover plate 2 that covers the trough body 1. To enable detachable assembly of the cover plate 2 and the trough body 1, a disassembly / removal part is provided between them. This disassembly / removal part consists of a long strip groove 3 extending along the length of the edge of the trough body 1 and a pressure strip 4 integrally formed on the lower end face of the cover plate 2. The pressure strip 4 is adapted to the long strip groove 3, and the cover plate 2 and the trough body 1 can be detachably connected through their interlocking engagement. A float-type heat insulation plate 5 for fire resistance and heat insulation is fixedly installed inside the trough body 1. When the cover plate 2 is placed on the trough body 1, the pressure strip 4 abuts against and presses against the upper surface of the float-type heat insulation plate 5, thereby restricting the displacement of the float-type heat insulation plate 5 inside the trough body 1. Multiple connecting parts for splicing are provided on the outer walls of both ends of the trough body 1. Adjacent trough bodies 1 can be spliced ​​through these connecting parts, thereby extending the overall length of the cable trough to meet the needs of cable trenches of different lengths.

[0017] The connecting part of the cable tray box specifically includes slots 6 opened on the outer wall surface at both ends of the tray body 1. The slots 6 of two adjacent tray bodies 1 are connected by a connecting plate 7. At the same time, a fixing hole 8 is opened inside the slot 6, and a connecting hole 9 is opened on the connecting plate 7 to be used with the fastener 10. When in use, the fastener 10 is passed through the connecting hole 9 on the connecting plate 7 and connected to the fixing hole 8 in the slot 6, so that the two tray bodies 1 can be firmly spliced ​​and fixed together, thereby realizing the function of extending the overall length of the cable tray box.

[0018] The cross-section of the fly ash insulation board 5 is designed in a mountain shape or a wave shape. This structural form can separate the cables inside the tank 1, making it convenient to classify and place different cables and avoid them from getting tangled together. At the same time, the fly ash material itself has fireproof and heat insulation properties, so that the fly ash insulation board 5 can not only realize the function of classifying and placing cables, but also provide fire protection for the cables inside the tank 1 and reduce the transfer of external heat to the inside of the tank 1, ensuring the safe operation of the cables.

[0019] The cable tray 1 and the cover plate 2 are made of lightweight insulating rubber. This lightweight property can reduce the overall weight of the cable tray box, making it easier to install and transport in the cable trench, and also reducing the difficulty of subsequent maintenance. Its insulating properties can effectively block current conduction, avoiding the risk of electric shock caused by current leakage, and isolating the external electric field from the interference of the cable inside the cable tray 1, ensuring stable power transmission of the cable.

[0020] The fly ash insulation board 5 uses strong adhesive as a fixing medium to form a connection and fixation with the inside of the tank 1. This fixing structure achieved by strong adhesive can ensure that the fly ash insulation board 5 maintains a stable position in the tank 1 and will not shift due to cable trench operation or slight external vibration. This allows the fly ash insulation board 5 to continuously and stably perform its fireproof and heat insulation function, while avoiding the impact of its own displacement on the classification and separation effect of cables, and providing a basic fixing guarantee for the safe operation of cables inside the tank 1.

[0021] The pressure strip 4 is a magnetic strip, and the long slot 3 is an iron strip. The magnetic strip and the iron strip can be magnetically attracted to each other. This magnetic structure design can make the connection between the cover plate 2 and the slot 1 tighter and more stable, preventing the cover plate 2 from loosening or falling off due to vibration or external force in the cable trench. On the other hand, compared with ordinary snap-fit, the magnetic attraction can achieve quick closing and disassembly of the cover plate 2 without complicated operation, improving the efficiency of disassembly and assembly. At the same time, when the magnetic strip pressure strip 4 is magnetically fixed, it can also continuously form a stable pressing force on the floating ball heat insulation plate 5, further limiting the displacement of the heat insulation plate and ensuring the stable performance of its fireproof heat insulation and cable separation functions.

[0022] The usage process of this utility model of a fire-resistant cable trough for cable trenches is as follows: First, according to the actual length requirements of the cable trench, take multiple sections of trough 1 made of lightweight insulating rubber, align the slot openings 6 on the outer walls of adjacent trough 1 ends, and connect them with connecting plates 7. Then, pass fasteners 10 through the connecting holes 9 of the connecting plates 7 and screw them into the fixing holes 8 in the slot openings 6 to complete the splicing of trough 1 and extend the overall length; next, use strong adhesive to attach and fix the beaded heat insulation board 5 with a mountain-shaped or wavy cross-section to the inside of the trough 1; subsequently, place the cables to be laid according to their type on the beaded heat insulation board 5. In the separated area, cables are arranged in categories. Finally, a cover plate 2, also made of lightweight insulating rubber, is placed over the trough 1, so that the magnetic strip (pressure strip 4) on the lower end of the cover plate 2 and the iron strip (long slot 3) on the edge of the trough 1 are tightly engaged by magnetic attraction, completing the connection between the cover plate 2 and the trough 1. At this time, the magnetic strip pressure strip 4 will simultaneously press the float heat insulation plate 5, further restricting its displacement. The float heat insulation plate 5 plays a role in fire prevention and heat insulation. The insulation between the trough 1 and the cover plate 2 avoids current interference and electric shock risk, ensuring the safe operation of the cable. During subsequent maintenance, the cover plate 2 can be quickly disassembled for operation with the help of the magnetic structure.
