Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a fireproof cable tray. Background Technology

[0002] Cable trays are devices for fixing cables. They can be installed independently or attached to various buildings and pipe rack supports. They are characterized by simple structure, beautiful appearance, flexible configuration and convenient maintenance. Cable trays can adopt closed or semi-closed structures. Since cables generate heat during operation, semi-closed cable trays are more popular. In order to improve the heat insulation and fire resistance of cable trays, fire-retardant coatings are sprayed on the inner wall of the tray. When the cable tray is exposed to fire, the fire-retardant coating layer expands and blocks the heat dissipation holes to achieve fire protection and heat insulation.

[0003] Since fire-retardant coatings are generally thin and have limited fire resistance, and the expanded and foamed fire-retardant coating layer blocks the heat dissipation holes and is difficult to restore and reuse, the cost of use is increased. In view of the above reasons, this application proposes a fire-resistant cable tray. Summary of the Invention

[0038] Example 1

[0039] like Figure 1-5 As shown, the present invention proposes a fireproof cable tray, including a base 1, a top cover 2 on the top of the base 1, multiple heat dissipation holes 3 on the inner walls of both sides of the base 1, two limiting grooves 4 for limiting and multiple rectangular grooves 5 for positioning on both sides of the base 1, the length of the limiting groove 4 is equal to half the longitudinal distance between the two heat dissipation holes 3, two protective covers 6 on both sides of the base 1, the protective covers 6 are located outside the multiple rectangular grooves 5, and a protective cover 7 is movably provided on the front of the protective cover 6. When the partition 901 is not adjusted, the protective cover 7 is in contact with the inner wall of the protective cover 6 and is in a closed fireproof state. Fire-resistant structures 8 are provided on both sides of the base 1.

[0040] like Figure 1 , Figure 4 and Figure 5As shown, the flame-arresting structure 8 includes a temperature-sensing bulb 801 for driving and two flame-arresting plates 802 for flame arrest. The surface of the flame-arresting plate 802 has multiple heat dissipation holes 805. The distribution spacing and diameter of the heat dissipation holes 805 and the heat dissipation holes 803 are the same. Two springs 803 are fixedly installed at the bottom of the flame-arresting plate 802. A horizontal plate 804 is fixedly installed at the bottom of each spring 803. The horizontal plate 804 is fixedly connected to the base 1. The flame-arresting plate 802 is movably connected to the limiting groove 4. Two connecting rods 806 are provided on one side of the flame-arresting plate 802. A locking block 807 is provided at the bottom end of each connecting rod 806. Push rods 808 are provided on both sides of the temperature-sensing bulb 801. A connecting rod 813 is movably installed inside each push rod 808. One end of each push rod 808 has a mounting cavity 809. The inner wall of the mounting cavity 809 has two sliding grooves 810 and a through hole 811. A disc is fixedly mounted on one end of the connecting rod 2 813. Two sliders are fixedly mounted on the outside of the disc. The sliders are movably connected to the slide groove 810. A positioning hole 814 is provided at the bottom of the connecting rod 2 813. The inner diameter of the positioning hole 814 and the through hole 811 are the same. An aluminum strip 812 is fixedly mounted on one side of the temperature sensing bulb 1 801. The aluminum strip 812 can transfer the temperature of the temperature sensing bulb 1 801 to the temperature sensing bulb 2 816 when the temperature sensing bulb 2 816 does not sense heat. The temperature sensing bulb 2 816 is fixedly mounted at the bottom of the push rod 1 808. A push rod 2 is provided at the top of the temperature sensing bulb 2 816. The push rod 2 is compatible with the positioning hole 814. The aluminum strip 812 is in contact with the bottom of the temperature sensing bulb 2 816. A locking block 2 815 is provided at the end of the connecting rod 2 813 away from the push rod 1 808. Both locking blocks 1 807 and locking blocks 2 815 are triangular. The inclined surfaces of locking blocks 1 807 and locking blocks 2 815 that are close to each other are parallel.

[0041] In this embodiment, when no fire occurs, the second locking block 815 is locked onto the first locking block 807. At this time, the second heat dissipation hole 805 on the fire arrestor plate 802 coincides with the first heat dissipation hole 3 on the side wall of the base 1, and is in a ventilation and heat dissipation state. If a fire occurs, the first heat sensor 801 and the second heat sensor 816 respectively drive the first push rod 808 and the second push rod. The second push rod is inserted into the positioning hole 814, and the first push rod 808 drives the second connecting rod 813. The second connecting rod 813 then drives the second locking block 815 at the top to move. When the second locking block 815 and the first locking block 807 separate, multiple first springs 803 push the fire arrestor plate 802 upward, and the fire arrestor plate 802 drives the second heat dissipation hole 805 upward, causing... The second heat dissipation hole 805 is completely offset from the first heat dissipation hole 3, which realizes the function of enclosing the cable tray and serves as a fireproofing measure. When the fire is extinguished and the temperature drops, both the first push rod 808 and the second push rod retract. The second push rod disengages from the positioning hole 814, and the first push rod 808 cannot drive the second connecting rod 813. The fire arrestor plate 802 can be manually reset to make the first heat dissipation hole 3 and the second heat dissipation hole 805 overlap, so that the cable tray is ventilated again. Finally, the second connecting rod 813 is pushed towards the first push rod 808, so that the second locking block 815 is locked above the first locking block 807. The first locking block 807 has an upward pushing force, which can make the second locking block 815 fit tightly with the first locking block 807.

[0042] Example 2

[0043] like Figure 2 and Figure 6 As shown, based on Embodiment 1, the base 1 is provided with multiple partition structures 9. Each partition structure 9 includes a partition 901 for placing cables. Mounting seats 902 are provided on both sides of the partition 901. A rectangular block 905 is movably mounted within each mounting seat 902, and the rectangular block 905 is adapted to a rectangular groove 5. A connecting plate 904 is fixedly mounted on one side of the rectangular block 905, and the connecting plate 904 is movably connected to the inner wall of the mounting seat 902. A second spring 903 is fixedly mounted on one side of the connecting plate 904, and the other end of the second spring 903 is fixedly connected to the inner wall of the mounting seat 902. Next, multiple partitions 901 can disperse the cables, thereby optimizing the heat dissipation performance of the equipment. By squeezing the rectangular block 905, when the rectangular block 905 retracts into the mounting base 902, it pulls the partition 901. The partition 901 drives the mounting base 902, and the mounting base 902 then drives the rectangular block 905. When the rectangular block 905 moves to the position of the next rectangular slot 5, the spring 903 causes the rectangular block 905 to reset and fix the partition 901, thereby realizing the adjustment of the position of adjacent partitions 901. It can be used to separate cables of different specifications and improve the versatility of the equipment.

[0044] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
