Technical Field
[0001] This utility model relates to the field of cable tray technology, specifically to a double-layer steel cable tray device with a built-in fireproof isolation layer. Background Technology
[0002] Cable trays are key facilities for cable laying in power, communication, and automation control systems. They are widely used in various scenarios such as industrial plants, commercial buildings, data centers, and traffic tunnels. They play an important role in supporting and protecting cables and optimizing cable layout. They can effectively prevent cables from being damaged by external forces such as pulling, squeezing, and corrosion. At the same time, they facilitate the installation, maintenance, and management of cables. Double-layer steel cable trays are one type of cable tray.
[0003] In existing cable tray installations, the fireproof insulation layer is usually welded and fixed to the cable tray. However, in actual use, the fireproof insulation layer is easily damaged during daily use and cannot be replaced quickly and conveniently. As a result, the entire cable tray needs to be replaced, which reduces the service life of the cable tray.
[0004] Therefore, we urgently need to provide a double-layer steel cable tray device with a built-in fireproof isolation layer. Utility Model Content
[0005] The purpose of this invention is to provide a double-layer steel cable tray device with a built-in fireproof isolation layer to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-layer steel cable tray device with a built-in fireproof isolation layer, including a cable tray, wherein a fireproof isolation plate is provided inside the cable tray, the outer side of the fireproof isolation plate is in contact with the inner wall of the cable tray, and an mounting plate is provided on one side of the fireproof isolation plate, wherein one side of the mounting plate is connected to one side of the fireproof isolation plate.
[0007] A further improvement is that an adjustment box is provided on one side of the cable tray, one end of the adjustment box is connected to one side of the cable tray, a limit rod is provided on the inner wall of the adjustment box, and the outer wall of the limit rod is slidably connected to the inner wall of the adjustment box.
[0008] A further improvement is that a blocking plate is provided on the outer wall of the limiting rod, the inner wall of the blocking plate is connected to the inner wall of the limiting rod, a reinforcing plate is provided on one side of the cable tray, a fixing plate is provided on the inner wall of the reinforcing plate, the outer wall of the fixing plate is sleeved with the inner wall of the reinforcing plate, and one end of the fixing plate is connected to one side of the cable tray.
[0009] A further improvement is that a connecting plate is provided on one side of the reinforcing plate, one end of the connecting plate is connected to one side of the reinforcing plate, a fixing bolt is provided on the inner wall of the connecting plate, and the outer wall of the fixing bolt is threadedly connected to the inner wall of the connecting plate.
[0010] A further improvement is that a limiting groove is provided on the inner side of the cable tray, one side of the mounting plate is slidably connected to the inner wall of the limiting groove, a limiting hole is provided on one side of the mounting plate, and one end of the limiting rod is inserted into the inner wall of the limiting hole, thereby enabling the fireproof isolation plate to be quickly and conveniently installed and removed, and thus enabling better use.
[0011] A further improvement is that a limiting groove is provided on the inner side of the cable tray, one side of the mounting plate is slidably connected to the inner wall of the limiting groove, a limiting hole is provided on one side of the mounting plate, one end of the limiting rod is inserted into the inner wall of the limiting hole, a partition plate is fixedly installed on the inner side of the cable tray, a guide rod is fixedly installed on the inner wall of the partition plate, an adjusting plate is slidably connected to the outer wall of the guide rod, an adjusting bolt is threadedly connected to the inner wall of the adjusting plate, and a clamping plate is fixedly installed on one side of the adjusting plate. This allows for quick and convenient adjustment of the position of the limiting rod, and enables the classification, organization, and fixing of cables of different sizes, thereby facilitating the assembly and disassembly of the fireproof isolation plate.
[0012] A further improvement is that there are two fixing plates, which are symmetrically distributed on both sides of the cable tray. One side of each fixing plate has a fixing hole, and one end of the fixing bolt is threaded into the inner wall of the fixing hole. This allows for quick and convenient assembly and disassembly of the two cable trays, thus enabling better use.
[0013] Compared with the prior art, the beneficial effects of this utility model are: This double-layer steel cable tray device with a built-in fireproof isolation layer achieves quick insertion and removal of the fireproof isolation plate through the cooperation of the adjustment box, limit rod, and mounting plate. During installation, the limit rod automatically engages with the limit hole on the mounting plate under the action of a spring. During disassembly, simply pulling the limit rod releases the lock, eliminating the need for welding or complex tools. This solves the problem of difficult replacement caused by traditional welding fixation, significantly shortens maintenance time, and extends the overall service life of the cable tray. The built-in fireproof isolation plate presses against the inner wall of the cable tray, forming a physical fire barrier that effectively blocks the spread of flames. Simultaneously, the sliding cooperation between the limit groove and the mounting plate ensures fire protection. After installation, the fire isolation panels fit tightly to prevent gaps from reducing fire resistance. The cable tray is constructed with a double-layer structure consisting of reinforcing plates, fixing plates, and fixing bolts. The fixing plates are fitted inside the reinforcing plates and secured with bolts, forming a stable mechanical support system. This not only improves the overall strength of the cable tray but also allows for flexible combinations to suit heavy-duty scenarios that carry a large number of cables. It reduces the risk of deformation due to insufficient load-bearing capacity, enables quick sorting and fixing of cables, and allows for quick and convenient adjustment of the spacing between multiple clamping plates. This allows for better clamping and fixing of cables of different sizes, resulting in better usability. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1-6 This utility model provides a technical solution: A double-layer steel cable tray device with built-in fireproof isolation layer includes a cable tray 1, a fireproof isolation plate 2 is provided inside the cable tray 1, the outer side of the fireproof isolation plate 2 is in contact with the inner wall of the cable tray 1, and an mounting plate 3 is provided on one side of the fireproof isolation plate 2, and one side of the mounting plate 3 is connected to one side of the fireproof isolation plate 2. A regulating box 4 is provided on one side of the cable tray 1. One end of the regulating box 4 is connected to one side of the cable tray 1. A limit rod 5 is provided on the inner wall of the regulating box 4. The outer wall of the limit rod 5 is slidably connected to the inner wall of the regulating box 4. A blocking plate 6 is provided on the outer wall of the limiting rod 5. The inner wall of the blocking plate 6 is connected to the inner wall of the limiting rod 5. A reinforcing plate 7 is provided on one side of the cable tray 1. A fixing plate 8 is provided on the inner wall of the reinforcing plate 7. The outer wall of the fixing plate 8 is sleeved with the inner wall of the reinforcing plate 7. One end of the fixing plate 8 is connected to one side of the cable tray 1. A connecting plate 9 is provided on one side of the reinforcing plate 7. One end of the connecting plate 9 is connected to one side of the reinforcing plate 7. A fixing bolt 10 is provided on the inner wall of the connecting plate 9. The outer wall of the fixing bolt 10 is threadedly connected to the inner wall of the connecting plate 9. A limiting groove is provided on the inner side of the cable tray 1. One side of the mounting plate 3 is slidably connected to the inner wall of the limiting groove. A limiting hole is provided on one side of the mounting plate 3. One end of the limiting rod 5 is inserted into the inner wall of the limiting hole, so that the fireproof isolation plate 2 can be quickly and conveniently disassembled and assembled, and thus can be used better. A limiting groove is provided on the inner side of the cable tray 1. One side of the mounting plate 3 is slidably connected to the inner wall of the limiting groove. A limiting hole is provided on one side of the mounting plate 3. One end of the limiting rod 5 is inserted into the inner wall of the limiting hole. A partition plate 11 is fixedly installed on the inner side of the cable tray 1. A guide rod 12 is fixedly installed on the inner wall of the partition plate 11. An adjusting plate 13 is slidably connected to the outer wall of the guide rod 12. An adjusting bolt 14 is threadedly connected to the inner wall of the adjusting plate 13. A clamping plate 15 is fixedly installed on one side of the adjusting plate 13. This allows for quick and convenient adjustment of the position of the limiting rod 5 and enables the classification and fixing of cables of different sizes, thereby facilitating the disassembly and assembly of the fireproof isolation plate 2. There are two fixing plates 8, which are symmetrically distributed on both sides of the cable tray 1. One side of the fixing plate 8 has a fixing hole, and one end of the fixing bolt 10 is threaded to the inner wall of the fixing hole, so that the two cable trays 1 can be quickly and conveniently disassembled and assembled, and thus can be used better.
[0018] When needed, the operator stacks two cable trays 1 and inserts the reinforcing plate 7 into the fixing plate 8. Then, the fixing bolt 10 is rotated to move within the connecting plate 9, allowing it to insert into the fixing plate 8 and thus securing the fixing plates 8 on both cable trays 1. This allows the two cable trays 1 to be joined together to form a double-layer steel cable tray. To disassemble the two cable trays 1, the above steps are repeated in reverse until the fixing bolt 10 is pulled out from one side of the fixing plate 8. When installing the fireproof isolation plate 2, the operator pulls the limiting rod 5 to slide it within the adjusting box 4. The sliding of the limiting rod 5 causes the blocking plate 6 to slide within the adjusting box 4, compressing the spring. The fireproof isolation plate 2 is then inserted into the cable tray 1, allowing the mounting plate 3 to insert into the limiting groove inside the cable tray 1. After insertion, the limiting rod 5 is released, and the spring force returns the limiting rod 5 to its original position, thus allowing the cable tray 1 to be installed. The limiting rod 5 is inserted into the mounting plate 3, thereby fixing the fireproof isolation plate 2 inside the cable tray 1. When the fireproof isolation plate 2 needs to be disassembled, the above steps are repeated in reverse to pull the limiting rod 5 out of the mounting plate 3, thereby canceling the limiting fixation of the fireproof isolation plate 2 and allowing the fireproof isolation plate 2 to be removed from the inside of the cable tray 1, completing the disassembly. The partition plate 11 can divide the space inside the cable tray 1, and the clamping plate 15 can classify, organize, and fix the cables. When it is necessary to clamp and fix cables of different sizes, the adjusting bolt 14 is rotated to move it on the inner wall of the adjusting plate 13. The movement of the adjusting bolt 14 can pull it out from one side of the guide rod 12, thereby canceling the limiting fixation of the adjusting plate 13. At this time, pulling the clamping plate 15 moves the adjusting plate 13 to slide on the guide rod 12, thereby adjusting the distance between the two clamping plates 15, thereby better limiting and fixing cables of different sizes, and thus better using them.
