Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, specifically to a novel fireproof aluminum alloy cable tray for cable protection. Background Technology

[0002] As an innovative product in the field of cable protection, the new type of fireproof aluminum alloy cable tray differs from ordinary aluminum alloy cable trays in three main dimensions. In terms of fire resistance, it can form an effective heat insulation barrier in a fire, making it suitable for key areas such as fire evacuation routes and power control rooms, while ordinary aluminum alloys have weaker fire resistance due to material limitations.

[0003] The existing cable tray design has a complex internal connection structure, occupies a lot of internal space, and has a high manufacturing cost, which is not conducive to its widespread use.

[0004] To overcome the above-mentioned defects, existing technology (Chinese patent publication number: CN220172775U, published on 2023-12-12) discloses a field-assembled fireproof cable tray, belonging to the technical field of fireproof cable trays. This field-assembled fireproof cable tray includes a first tray and a second tray. The top of the first and second trays are fitted with tray covers. Connecting blocks are fixedly connected to the top and bottom of both sides of the first tray, and mounting holes are provided inside the connecting blocks. Fixing plates are fixedly connected to both sides of the second tray, and insert plates are fixedly connected to the top and bottom of the fixing plates. Movable insertion holes are provided on the connecting blocks. A locking plate is provided between the connecting blocks, and an insert rod is movably sleeved inside the top of the locking plate. This field-assembled fireproof cable tray, through the fixing plates, connecting blocks, mounting holes, locking plates, insert rods, first locking slots, and second... The interlocking of the slots allows for quick connection of two cable trays, simplifying operation, reducing labor costs, and improving the structure and manufacturing cost, which is conducive to widespread use. Furthermore, existing technology (Chinese Patent No. CN220172775U, published on 2023-12-12) discloses a field-assembled fireproof cable tray, belonging to the field of fireproof cable tray technology. This field-assembled fireproof cable tray includes a first tray and a second tray. The tops of the first and second trays are fitted with tray covers. Connecting blocks are fixedly connected to the top and bottom of both sides of the first tray, and mounting holes are provided inside the connecting blocks. Fixing plates are fixedly connected to both sides of the second tray, and insert plates are fixedly connected to the top and bottom of the fixing plates. Movable insertion holes are provided on the connecting blocks, and a locking plate is provided between the connecting blocks. An insert rod is movably sleeved inside the top of the locking plate. The fireproof cable trays assembled on-site enable two trays to be quickly connected through the cooperation of fixing plates, connecting blocks, mounting holes, clamping plates, insert rods, first clamping slots, and second clamping slots. The operation is simple and labor-saving, the structure is simple, the manufacturing cost is low, and it is conducive to widespread use.

[0005] While the above design can solve the aforementioned problems, the connection strength of the existing design is insufficient when the equipment needs to be installed. After long-term use, the equipment will deform, which will reduce the protection effect of the internal cables. At the same time, the protection effect of the existing design is relatively simple. High temperature or high internal humidity will also affect the operation of the cables, making the equipment less stable and safe to use. Utility Model Content

[0006] The purpose of this utility model is to provide a new type of fireproof aluminum alloy cable tray for cable protection, in order to solve the problems mentioned in the background art, such as insufficient connection strength of existing designs when installing equipment, deformation of the equipment after long-term use, resulting in poor protection of internal cables, and relatively simple protection effect of existing designs. High temperature or high internal humidity can also affect the operation of cables, making the use of equipment unstable and unsafe.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel fireproof aluminum alloy cable tray for cable protection, comprising an aluminum alloy protective box, a top protective cover installed on the top of the aluminum alloy protective box, a fixing engagement mechanism for engaging a semi-circular extension rod installed inside the top protective cover, the fixing engagement mechanism including a supporting sliding frame, and the supporting sliding frame being fixedly installed on the left and right sides of the aluminum alloy protective box, a second U-shaped frame installed on the inner surface of the top protective cover, and a docking moisture-proof mechanism for protecting the cable exterior installed on the outer surface of the second U-shaped frame.

[0008] Furthermore, the docking moisture-proof mechanism includes an internal limiting groove, which is fixedly installed on the inner surface of the aluminum alloy protective box. The internal sliding trajectory of the top protective cover corresponds to the installation position of the internal limiting groove, and a first U-shaped frame is installed at the bottom of the inner surface of the aluminum alloy protective box.

[0009] Furthermore, the first U-shaped frame and the second U-shaped frame are designed to be symmetrical, and the inner surfaces of the first U-shaped frame and the second U-shaped frame are equipped with semi-circular anti-slip plates, and the inner surface of the aluminum alloy protective box is equipped with side fireproof netting.

[0010] Furthermore, the semi-circular extension rod is slidably installed inside the aluminum alloy protective box, and a compression spring is installed on the outer surface of the semi-circular extension rod. The end of the compression spring abuts against the inner surface of the supporting sliding frame, and an extension connecting rod is installed at the end of the semi-circular extension rod.

[0011] Furthermore, a lateral limiting frame is installed on the upper surface of the top protective cover, and the extended connecting rod slides laterally along the inside of the lateral limiting frame. A rotating traction rod is installed at the other end of the extended connecting rod, and a downward transmission rod is installed at the other end of the rotating traction rod.

[0012] Furthermore, the two ends of the rotating traction rod are rotatably connected to the extension connecting rod and the downward transmission rod, respectively, and the left and right sides of the aluminum alloy protective box are provided with mating and interlocking inner grooves, and the opening position of the mating and interlocking inner grooves corresponds to the contraction trajectory of the semi-circular extension rod.

[0013] Furthermore, the side fireproof net is installed in close contact with the left and right sides of the first U-shaped frame and the second U-shaped frame, and a through output pipe is installed on the lower surface of the first U-shaped frame. Moreover, the first U-shaped frame, the second U-shaped frame, the side fireproof net, the through output pipe and the semi-circular anti-slip plate are installed in three sets at the center point of the aluminum alloy protective box.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the top protective cover of the new aluminum alloy fireproof trough box for cable protection needs to be fixed, the aluminum alloy protective box and the top protective cover are directly slidably connected. At this time, the front end of the semi-circular extension rod will enter the interior of the interlocking groove. During this process, the compression spring will press the semi-circular extension rod inward and fix it. This design makes the connection strength of the equipment higher, and the equipment will not deform after long-term use, thus improving the protection effect of the cable.

[0015] Furthermore, after the aluminum alloy protective box and the top protective cover are connected, the first U-shaped frame and the second U-shaped frame will be connected to each other, so that the outside of the cable is completely protected. At the same time, the side fireproof mesh design will provide efficient heat insulation for the cable when high temperatures are generated inside the equipment.

[0016] Furthermore, a through-output pipe is designed at the lower end of the first U-shaped frame, which can provide efficient protection when a lot of moisture or even liquid is generated inside the joint between the first U-shaped frame and the second U-shaped frame, thus improving the overall usability of the equipment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Example 1: Please refer to Figure 2 , Figure 3 and Figure 4 This utility model provides the following technical solution: a novel fireproof aluminum alloy cable tray for cable protection, comprising an aluminum alloy protective box 1, a top protective cover 2 installed on the top of the aluminum alloy protective box 1, and a fixing and engaging mechanism for engaging a semi-circular extension rod 10 installed inside the top protective cover 2. Figure 3 As shown, the fixed engagement mechanism includes a support sliding frame 5, which is fixedly installed on the left and right sides of the aluminum alloy protective box 1. A second U-shaped frame 13 is installed on the inner surface of the top protective cover 2, and a docking moisture-proof mechanism for protecting the cable is installed on the outer surface of the second U-shaped frame 13.

[0026] like Figure 2 , Figure 3 and Figure 4 The technical solution shown, in order to solve the problem of inconvenient manual maintenance in case of malfunction, discloses that: a semi-circular extension rod 10 is slidably installed inside the aluminum alloy protective box 1, and a compression spring 11 is installed on the outer surface of the semi-circular extension rod 10. The end of the compression spring 11 abuts against the inner surface of the supporting sliding frame 5, and an extension connecting rod 6 is installed at the end of the semi-circular extension rod 10. A transverse limiting frame 4 is installed on the upper surface of the top protective cover 2. Figure 4As shown, the extension connecting rod 6 slides laterally along the interior of the transverse limiting frame 4. A rotating traction rod 7 is installed at the other end of the extension connecting rod 6, and a pressing transmission rod 8 is installed at the other end of the rotating traction rod 7. The two ends of the rotating traction rod 7 are rotatably connected to the extension connecting rod 6 and the pressing transmission rod 8, respectively. The left and right sides of the aluminum alloy protective box 1 are provided with mating and interlocking inner grooves 9, and the opening position of the mating and interlocking inner grooves 9 corresponds to the contraction trajectory of the semi-circular extension rod 10.

[0027] When assembling the aluminum alloy protective box 1, the top protective cover 2 is slid along the top of the aluminum alloy protective box 1. The movement of the top protective cover 2 will synchronously move the supporting sliding frames 5 fixed on both sides. Simultaneously, the semi-circular extension rods 10 nested and slidably installed inside the supporting sliding frames 5 will move synchronously. The ends of the semi-circular extension rods 10 will slide against the side of the aluminum alloy protective box 1 until they move into the mating grooves 9 on the side of the aluminum alloy protective box 1. Figure 4 As shown, at this time, the compression spring 11 nested on the outer surface of the semicircular extension rod 10 will release elastic potential energy to push the semicircular extension rod 10 against the opposite direction until the mating engagement groove 9 and the semicircular extension rod 10 are mated. When it is necessary to remove the top protective cover 2, the downward pressing transmission rod 8 is directly pressed down, so that the downward pressing transmission rod 8 drives the rotating traction rod 7 installed at both ends to move laterally in a synchronous manner. At this time, the rotating traction rod 7 will simultaneously drive the extension connecting rod 6 installed at the other end in the same direction. Since the extension connecting rod 6 is fixedly installed at the end of the semicircular extension rod 10, the semicircular extension rod 10 can be pulled outward until it is disengaged from the interior of the mating engagement groove 9. This design makes the use of the equipment more convenient and efficient.

[0028] Example 2: Figure 1 , Figure 5 and Figure 6 The technical solution shown, in order to solve the problem of inconvenient manual maintenance after a malfunction, discloses the following: the docking moisture-proof mechanism includes an internal limiting groove 3, which is fixedly installed on the inner surface of the aluminum alloy protective box 1. The internal sliding trajectory of the top protective cover 2 corresponds to the installation position of the internal limiting groove 3. A first U-shaped frame 12 is installed at the bottom of the inner surface of the aluminum alloy protective box 1. The first U-shaped frame 12 and the second U-shaped frame 13 are designed symmetrically. Semi-circular anti-slip plates 16 are installed on the inner surfaces of the first U-shaped frame 12 and the second U-shaped frame 13. Furthermore, a side fireproof mesh 14 is installed on the inner surface of the aluminum alloy protective box 1. Figure 5As shown, the side fireproof net 14 is installed in close contact with the left and right sides of the first U-shaped frame 12 and the second U-shaped frame 13, and a through output pipe 15 is installed on the lower surface of the first U-shaped frame 12. The first U-shaped frame 12, the second U-shaped frame 13, the side fireproof net 14, the through output pipe 15 and the semi-circular anti-slip plate 16 are installed in three sets at the center point of the aluminum alloy protective box 1.

[0029] During the docking of the aluminum alloy protective box 1 and the top protective cover 2, the interior of the top protective cover 2 slides along the internal limiting groove 3 fixedly installed inside the aluminum alloy protective box 1. This movement of the top protective cover 2 synchronously drives the second U-shaped frame 13 fixedly installed on the inner surface. As the second U-shaped frame 13 moves, its end slides against the top of the first U-shaped frame 12 fixedly installed at the corresponding position on the inner surface of the aluminum alloy protective box 1. The docking point between the first U-shaped frame 12 and the second U-shaped frame 13 forms a sealed space. Figure 6 As shown, the cable can be installed inside the joint between the first U-shaped frame 12 and the second U-shaped frame 13. During the installation process, the cable will come into contact with the corresponding semi-circular anti-slip plates 16 fixedly installed inside the first U-shaped frame 12 and the second U-shaped frame 13. The design of the upper and lower sets of semi-circular anti-slip plates 16 will prevent the cable from falling off and slipping out. This design makes the use of the equipment more stable. At the same time, when high temperatures or even fire sources are generated outside the equipment, the side fireproof nets 14 fixedly installed on both sides of the first U-shaped frame 12 and the second U-shaped frame 13 will isolate the high temperature and fire source, improving the safety of the equipment. Furthermore, when the humidity inside the equipment is high or there is a risk of water ingress, the through-outlet pipe 15 designed inside the first U-shaped frame 12 will stably discharge the moisture, improving the practicality and safety of the equipment.
