Description

Technical Field

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

[0002] Fireproof cable trays are mainly suitable for laying computer cables, communication cables, thermocouple cables, and other control cables for highly sensitive systems. They are effective in shielding control cables from interference and protecting cables in heavily corrosive environments.

[0003] Existing fire-resistant cable trays may require multiple cables of different types or sizes to be laid simultaneously within the same tray. This can easily lead to cable crossings, making subsequent maintenance difficult. Furthermore, the crossing of cables can cause heat concentration during operation, which is detrimental to long-term cable performance. To address this issue, some fire-resistant cable trays incorporate guide blocks with fixed-size guide slots to guide multiple cables and prevent crossings. However, the size of these guide slots is not adjustable. Depending on the cable size and the number of cables laid, the entire guide block needs to be replaced, resulting in inflexibility and poor compatibility. Utility Model Content

[0004] The main purpose of this utility model is to propose a fireproof trough-type cable tray, which aims to solve the technical problems of the existing fireproof trough-type cable trays being inflexible and having poor compatibility.

[0005] To achieve the above objectives, this utility model proposes a fireproof trough-type cable tray, comprising:

[0006] The bridge body extends laterally and encloses a receiving space for accommodating cables. The receiving space extends laterally and penetrates the bridge body. An opening communicating with the receiving space is provided at the top of the bridge body.

[0007] An isolation assembly includes a support platform and two independent isolation columns. The support platform is longitudinally disposed at the bottom of the receiving space, and each isolation column is vertically disposed. The bottom end of each isolation column is slidably connected to the support platform longitudinally, and the two isolation columns are distributed along the longitudinal direction. A guide channel for the cable to pass through can be formed between each side wall of the receiving space along the longitudinal direction and between the adjacent isolation columns and between the two isolation columns.

[0008] A cover plate is placed on top of the bridge body and closes the opening. A positioning block extending longitudinally is provided at the bottom of the cover plate and at the position corresponding to the support platform. The positioning block extends into the receiving space and the bottom of the positioning block abuts against the top of each of the isolation columns. The two ends of the positioning block abut against the two side walls of the receiving space along the longitudinal direction.

[0009] In one embodiment, the bridge body includes a base plate extending laterally and two guard plates, the two guard plates being spaced apart on top of the base plate along the longitudinal direction, the base plate and the two guard plates together forming the receiving space, the two guard plates respectively forming two side walls of the receiving space along the longitudinal direction; the support platform is disposed on top of the base plate, and the two ends of the support platform abut against the two guard plates along the longitudinal direction.

[0010] The isolation assembly also includes adjusting rods that correspond one-to-one with the two isolation columns. The two adjusting rods are respectively inserted longitudinally through the two protective plates, and one end of each adjusting rod extends into the receiving space and connects to the corresponding isolation column. Each adjusting rod is used to drive the corresponding isolation column to slide relative to the support platform along the longitudinal direction.

[0011] In one embodiment, the top of the support platform is provided with a downwardly recessed groove, and the groove extends along the longitudinal direction, with the bottom of each of the isolation columns extending into the groove and slidingly engaging with the groove wall.

[0012] Each of the adjusting rods is an adjusting screw, and each adjusting screw is rotatably inserted through the corresponding protective plate. Each of the isolation columns has a screw hole near the bottom. One end of each adjusting screw extends into the groove and is threadedly connected to the corresponding screw hole.

[0013] In one embodiment, the groove has a limiting groove formed on the two opposite side walls of the groove along the transverse direction, and the bottom of the isolation column is provided with limiting protrusions on both opposite sides of the transverse direction. The two limiting protrusions extend into the two limiting grooves respectively, and each limiting protrusion slides into the corresponding limiting groove.

[0014] In one embodiment, the isolation assembly further includes a partition plate having a clearance hole extending along the longitudinal direction. Both isolation posts pass through the clearance hole and slide in contact with the clearance hole along opposite sides of the transverse direction. The partition plate slides in contact with the two guard plates along opposite sides of the longitudinal direction, and the partition plate can slide vertically relative to the support platform.

[0015] In one embodiment, the partition is locked to or unlocked from the corresponding guard plate on both sides along the longitudinal direction by fastening bolts, and each guard plate has a through hole for the corresponding fastening bolt to pass through, and each through hole extends vertically.

[0016] In one embodiment, the base plate extends longitudinally from both ends toward the direction away from the receiving space to form two extension plates, and the cover plate is connected to both ends longitudinally with connecting plates. The two connecting plates and the two extension plates are correspondingly arranged, and the bottom of each connecting plate is detachably connected to the corresponding extension plate.

[0017] In one embodiment, there is a gap between each of the connecting plates and the adjacent guard plate in the longitudinal direction.

[0018] In one embodiment, each of the protective plates has a plurality of first heat dissipation holes communicating with the receiving space, and the plurality of first heat dissipation holes are distributed at intervals along the lateral direction; each of the connecting plates has a plurality of second heat dissipation holes, and the plurality of second heat dissipation holes are distributed at intervals along the lateral direction.

[0019] The plurality of first heat dissipation holes on the protective plate and the plurality of second heat dissipation holes on the adjacent connecting plate are arranged alternately.

[0020] In one embodiment, the number of isolation components is multiple, and the multiple isolation components are evenly arranged along the lateral interval.

[0021] This fireproof trough-type cable tray features an isolation component within its accommodating space. This component includes a support platform and isolation columns. Two isolation columns can longitudinally divide the space into up to three guide channels for cable laying. By separating different types of cables through different guide channels during laying, entanglement and crossing between different types of cables are prevented, thus preventing heat concentration during cable operation and ensuring long-term stable operation of each cable. Furthermore, each isolation column can slide along the support platform; by adjusting the position of each isolation column, guide channels of different sizes can be created, adapting to guide cables of different sizes, making it more flexible and compatible.

[0022] Furthermore, after the cable is laid, it can be clamped by moving the isolation column. A positioning block is set at the bottom of the cover plate, and the bottom of the positioning block abuts against the top of the isolation column. The positioning block can not only quickly and accurately position the cover plate on the bridge body for easy installation, but also limit the cable to prevent it from moving out of the guide channel, making it more reliable.

[0034] This utility model proposes a fireproof trough-type cable tray 100.

[0035] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the fireproof cable tray 100 includes a bridge body 1, an isolation component 2, and a cover plate 3. The bridge body 1 extends laterally and forms a receiving space 11 for accommodating cables. The receiving space 11 extends laterally and penetrates the bridge body 1. An opening 12 communicating with the receiving space 11 is provided at the top of the bridge body 1. The isolation component 2 includes a support platform 21 and two independent isolation columns 22. The support platform 21 is longitudinally disposed at the bottom of the receiving space 11, and each isolation column 22 is vertically disposed. The bottom end of each isolation column 22 is slidably connected longitudinally to the cable tray 3. The support platform 21 and the two isolation columns 22 are distributed longitudinally. The longitudinal side walls of the accommodating space 11 and the adjacent isolation columns 22 can form a guide channel for the cable to pass through. The cover plate 3 is placed on the top of the bridge body 1 and closes the opening 12. The bottom of the cover plate 3 and the position corresponding to the support platform 21 are provided with a positioning block 31 extending longitudinally. The positioning block 31 extends into the accommodating space 11 and the bottom of the positioning block 31 abuts against the top of each isolation column 22. The two ends of the positioning block 31 abut against the two longitudinal side walls of the accommodating space 11 respectively.

[0036] The fireproof trough-type cable tray 100 of this utility model has an isolation component 2 installed in the accommodating space 11 of the cable tray 1. The isolation component 2 includes a support platform 21 and isolation columns 22. The two isolation columns 22 can divide the longitudinal direction into up to three guide channels for cable laying and to guide the cables. By separating different types of cables through different guide channels during the laying process, different types of cables are prevented from tangling and crossing each other, thereby preventing the heat generated by the cables from concentrating and ensuring the long-term stable operation of each cable. In addition, each isolation column 22 can move along the support platform 21. By adjusting the position of each isolation column 22, guide channels of different sizes can be divided, thereby adapting to guide cables of different sizes and making it more flexible.

[0037] Furthermore, after the cable is laid, the cable can be clamped by moving the isolation column 22. A positioning block 31 is provided at the bottom of the cover plate 3. The bottom of the positioning block 31 abuts against the top of the isolation column 22. The positioning block 31 can not only quickly and accurately position the cover plate 3 onto the bridge body 1 for easy installation, but also limit the cable to prevent it from moving out of the guide channel, making it more reliable.

[0038] like Figure 1 As shown, it should be noted that the horizontal, vertical, and longitudinal directions are respectively... Figure 1 The front-back, left-right, and up-down directions.

[0039] Understandably, by adjusting the positions of the two isolation posts 22, one, two, or three guide channels can be formed. For example, when the two isolation posts 22 are adjusted to the left and right sides of the support platform 21 respectively, a maximum guide channel is formed between the two isolation posts 22; when both isolation posts 22 are adjusted to the middle, two guide channels are formed; or one isolation post 22 is located in the middle and the other is located at the edge of the support platform 21, which can also form two guide channels; when neither isolation post 22 is at the edge of the support bar and there is a gap between the two isolation posts 22, three guide channels are formed. Therefore, depending on the different positions of the two isolation posts 22, different numbers of guide channels can be formed, thus adapting to the laying of various types or quantities of cables, providing greater flexibility.

[0040] It should be noted that both the cover plate 3 and the bridge body 1 are made of fire-retardant materials, or are coated with fire-retardant paint, which provides good fire protection and heat insulation for the cable.

[0041] Please combine Figure 2 and Figure 3In one embodiment, the bridge body 1 includes a base plate 13 extending laterally and two guard plates 14. The two guard plates 14 are longitudinally spaced on top of the base plate 13, and the base plate 13 and the two guard plates 14 together form an accommodating space 11. The two guard plates 14 respectively form two side walls of the accommodating space 11 along the longitudinal direction. A support platform 21 is disposed on top of the base plate 13, and the two ends of the support platform 21 abut against the two guard plates 14 along the longitudinal direction. The isolation assembly 2 also includes adjusting rods 23 corresponding to the two isolation columns 22. The two adjusting rods 23 are respectively longitudinally inserted through the two guard plates 14, and one end of each adjusting rod 23 extends into the accommodating space 11 and connects to the corresponding isolation column 22. Each adjusting rod 23 is used to drive the corresponding isolation column 22 to slide longitudinally relative to the support platform 21.

[0042] Understandably, by setting two adjusting rods 23 on the two guard plates 14 respectively, and connecting the two adjusting rods 23 to the two isolation rods respectively, when adjusting the isolation column 22, it is not necessary to put your hand into the receiving space 11 to move the adjusting rod 23. The position of the corresponding isolation rod can be adjusted through the isolation column 22. In addition, the adjusting rod 23 can also provide a certain support and positioning for the isolation rod, which can prevent the isolation rod from tilting to the left or right.

[0043] Please combine further Figure 4 In one embodiment, the top of the support platform 21 is provided with a downwardly recessed groove 211, and the groove 211 extends longitudinally. The bottom of each isolation column 22 extends into the groove 211 and slides in cooperation with the groove wall of the groove 211. Each adjusting rod 23 is an adjusting screw, and each adjusting screw is rotatably inserted through the corresponding guard plate 14. Each isolation column 22 is provided with a screw hole near the bottom. One end of each adjusting screw extends into the groove 211 and is threadedly connected to the corresponding screw hole.

[0044] By providing a groove 211 at the top of the support platform 21, the bottom of the isolation column 22 extends into the groove 211 and slides within it, thus constraining the sliding direction of the isolation column 22. This effectively prevents the isolation column 22 from shifting or swaying, and also prevents it from tilting forward or backward, improving its stability. Furthermore, by using an adjusting screw as the adjusting rod 23, and with a threaded hole on the isolation column 22 for threaded connection, the adjusting screw is rotatably mounted on the protective plate 14. Rotating the adjusting screw does not change its position on the protective plate 14, but allows the isolation column 22 to move left or right. By changing the direction of rotation of the adjusting screw, the isolation column 22 can be moved to the left or right.

[0045] Understandably, the adjusting screw extends longitudinally and is inserted into the groove 211 to avoid the adjusting screw occupying the receiving space 11 and affecting the laying of the cable.

[0046] In another embodiment, the adjusting member may also use a micrometer head or the like to move the corresponding isolation column 22 left and right.

[0047] In one embodiment, the groove 211 has limiting grooves 212 formed along its two opposite sidewalls in the transverse direction. The bottom of the isolation column 22 has limiting protrusions 221 on both opposite sides in the transverse direction. The two limiting protrusions 221 extend into the two limiting grooves 212 respectively, and each limiting protrusion 221 slides into its corresponding limiting groove 212. By forming limiting grooves 212 on both sides of the groove 211 and providing limiting protrusions 221 on both sides of the isolation column 22, with the limiting protrusions 221 extending into the limiting grooves 212, the stability of the isolation column 22 is further improved, preventing it from tipping over.

[0048] In one embodiment, the isolation assembly 2 further includes a partition 24, on which a longitudinally extending clearance hole 241 is provided. Both isolation posts 22 pass through the clearance hole 241 and slide in contact with the clearance hole 241 along the opposite sides of the transverse side wall. The partition 24 slides in contact with the two guard plates 14 along the opposite sides of the longitudinal side, and the partition 24 can slide vertically relative to the support platform 21.

[0049] By setting a partition 24, which has clearance holes 241 for two isolation posts 22 to pass through, each isolation post 22 contacts the opposite side walls of the clearance hole 241 in the transverse direction, that is, it contacts the front and rear side walls of the clearance hole 241, further restricting the forward and backward tilting of the isolation post 22 and improving stability. The clearance holes 241 extend in the longitudinal direction, that is, they do not restrict the left and right movement of the isolation post 22. In addition, the main function of the partition 24 is to divide the space into layers, thereby cooperating with the two isolation posts 22 to obtain up to six guide channels, thus accommodating more numbers and types of cables. Furthermore, the partition 24 can move up and down, cooperating with the isolation posts 22 to accommodate cables of different sizes, further improving flexibility.

[0050] In one embodiment, the partition 24 is locked to or unlocked from the corresponding guard plate 14 on both sides along the longitudinal direction by fastening bolts 242. Each guard plate 14 has a through hole through which the corresponding fastening bolt 242 passes, and each through hole extends vertically.

[0051] Understandably, each fastening bolt 242 passes through the corresponding through hole and is threaded to the partition 24 to lock the partition 24 onto or unlock it from the protective plate 14, thereby facilitating the up-and-down movement and disassembly of the partition 24. Users can flexibly adjust the installation position of the partition 24 according to the cable outer diameter, the number of cables laid, or the heat dissipation requirements to maximize the use of the accommodating space 11. When the partition 24 is moved up and down to the appropriate position, the fastening bolts 242 can be used to lock and limit the partition 24.

[0052] Furthermore, depending on specific practical needs, the partition 24 can be removed, or different numbers of partitions 24 can be used to form more guide channels, thus improving flexibility and versatility.

[0053] Please see Figure 2 and Figure 3 In one embodiment, the base plate 13 extends along both ends in the longitudinal direction away from the receiving space 11 to form two extension plates 131. The cover plate 3 is connected to both ends along the longitudinal direction by a connecting plate 32. The two connecting plates 32 and the two extension plates 131 are correspondingly arranged, and the bottom of each connecting plate 32 is detachably connected to the corresponding extension plate 131.

[0054] Understandably, by connecting the connecting plate 32 and the corresponding extension plate 131, the connection stability between the cover plate 3 and the bridge body 1 is improved, and double protection is formed on both sides of the cable, resulting in better fire resistance.

[0055] Moreover, the positioning block 31 and the support platform 21 can not only limit the cable, but also guide the cable to the center area of ​​the receiving space 11, reducing the contact area between the cable and the floor or cover plate 3, improving the heat dissipation effect and the fireproof effect.

[0056] In one embodiment, a gap exists between each connecting plate 32 and its adjacent corresponding protective plate 14 along the longitudinal direction. This gap between the connecting plate 32 and the protective plate 14 helps to conceal the adjusting screw, preventing external interference during subsequent use. Furthermore, in the event of a fire, the gap increases the distance between the cable and the outside environment, improving fire resistance and providing some heat insulation.

[0057] Please see Figure 2 In one embodiment, each protective plate 14 is provided with a plurality of first heat dissipation holes 141 communicating with the receiving space 11, and the plurality of first heat dissipation holes 141 are distributed laterally at intervals; each connecting plate 32 is provided with a plurality of second heat dissipation holes 321, and the plurality of second heat dissipation holes 321 are distributed laterally at intervals; the plurality of first heat dissipation holes 141 on the protective plate 14 and the plurality of second heat dissipation holes 321 on the adjacent connecting plate 32 are arranged alternately.

[0058] By setting the first heat dissipation hole 141 and the second heat dissipation hole 321, the outside air can be exchanged and circulated with the air inside the housing space 11, which helps to dissipate the heat generated by the cable during operation through the first heat dissipation hole 141 and the second heat dissipation hole 321. In addition, by staggering the first heat dissipation hole 141 and the second heat dissipation hole 321, most of the dust entering from the second heat dissipation hole 321 is first blocked in the gap by the protective plate 14, thereby reducing the direct entry of external dust into the housing space 11 and preventing the accumulation of dust in the housing space 11 over a long period of time, which would affect maintenance and heat dissipation.

[0059] In one specific embodiment, the first heat dissipation hole 141 and the through hole have the same shape and size. The first heat dissipation hole 141 can also be regarded as a through hole. More specifically, a mounting hole for the adjusting bolt to pass through is provided below the first heat dissipation hole 141 so as to install the isolation component 2 at any position of the bridge body 1 and improve flexibility.

[0060] Please see Figure 2 In one embodiment, there are multiple isolation components 2, and these multiple isolation components 2 are evenly spaced laterally. By setting multiple isolation components 2 to guide the cable laying multiple times, cable crossing and entanglement are further avoided, resulting in better reliability.

[0061] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
