Description

Technical Field

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

[0002] Cable trays are structures used to support and protect cables and wires. Their main function is to provide a stable path for neatly arranging and fixing cables and wires, so as to facilitate cable laying, maintenance and management. However, cable trays are difficult to install and inconvenient to use.

[0003] Based on the above problems, the existing patent with publication number CN221227018U discloses a new type of composite fireproof cable tray. By holding two handles and pulling two pull plates, four locking rods are retracted into the inside of the cover plate. The cover plate is placed on the top of the U-shaped plate. Releasing the pull plates allows the four locking rods to be inserted into the four locking slots simultaneously to complete the fixed installation, achieving the effect of easy installation.

[0004] However, when implementing the aforementioned new type of composite fireproof cable tray, at least the following problems were found: the installation of the cable tray usually requires passing the cable through the inside of the cable tray and pulling or feeding the cable from one end of the cable tray to the other end. When the cable tray is short, the cable can be passed through relatively easily, but if the cable tray is long, the cable is prone to bending during the feeding process, and the end of the cable fed into the cable tray is prone to abutting against the inner wall of the cable tray, causing the cable to accumulate inside the cable tray and making it difficult to feed it out from the other end of the cable tray. The installer needs to adjust the feeding angle multiple times to feed the cable out. Especially when feeding multiple cables, the already installed cables can easily restrict the feeding position of subsequent cables, affecting the feeding of subsequent cables. Therefore, a new type of composite fireproof cable tray is proposed to solve the above-mentioned problems. Utility Model Content

[0028] 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.

[0029] Example: Please refer to Figures 1 to 6According to an embodiment of this utility model, a technical solution is provided: a novel composite fireproof cable tray, comprising: a cable tray body 1, the top of which is suitable for installation on a wall top; a sliding rail 2 is provided on one side of the inner wall of the cable tray body 1, and a sliding groove 3 is provided on the other side; a cable puller 4, which has a cable pull hole 5 inside, through which cables can pass. It should be noted that the cable is wrapped with a plastic layer on one side. The degree of bending and the rebound force of the cable after bending will change with the thickness of the plastic layer. When the cable is inserted into the cable pull hole 5, the cable is bent by rotating the cable puller 4. At this time, the cable is bent under force and rebounds. The cable rebounds under force continuously. The cable tie 4 abuts against the cable puller 4, thereby securing the cable. At this point, the cable puller 4 can be dragged to move one end of the cable. The thinner the plastic layer, the greater the rotation angle of the cable puller 4. If the cable is thin, the cable puller 4 can be rotated 360°-720° to wind the cable around the cable puller 4 for movement. One end of the cable puller 4 is fixed with a slide rod 6, which is embedded in the sliding rail 2 and slidably connected within the sliding rail 2. The other end of the cable puller 4 is fixed with a connecting rod 7, which is slidably connected within the sliding groove 3 and protrudes from the cable tray body 1. A handle 8 is fixed to the end of the connecting rod 7 that protrudes from the cable tray body 1, and the handle 8 can drive the cable puller 4 to rotate.

[0030] The novel composite fireproof cable tray with the above structure allows multiple cables to be inserted into the cable-pulling hole 5 of the cable-pulling component 4 at one end. Then, the cable-pulling component 4 is rotated by the handle 8, causing the multiple cables to be clamped or wrapped around the cable-pulling component 4. At this time, the handle 8 can be dragged to make the cable-pulling component 4 and the multiple cables slide in the sliding rail 2 and the sliding groove 3, thereby dragging the multiple cables along one end of the cable tray body 1 to the other end. This novel composite fireproof cable tray has a simple structure and low operation difficulty, and can quickly pull multiple cables along one end of the cable tray to the other end, solving the problem of difficult cable delivery after the cable tray is installed in the prior art.

[0031] In this embodiment, in order to maintain the stability of the cable puller 4 during movement and prevent the cable puller 4 from tilting when the handle 8 is pulled, and to ensure the stability of the cable delivery, both ends of the cable puller 4 need to be attached to the inner wall of the cable tray body 1. In this way, when the cable puller 4 moves along the sliding track 2 and the sliding groove 3, the two ends are attached to the inner wall of the cable tray body 1, which reduces the possible shaking or deviation of the cable puller 4, thereby making the movement of the cable more stable and controllable.

[0032] In this embodiment, the cable tray body 1 includes an upper cable tray 101 and a lower cable tray 102, which can improve the convenience of production and transportation and facilitate quick installation. The upper cable tray 101 is provided with quick-installation slots 9 on both sides, and the lower cable tray 102 is provided with a quick-installation extension 10 that is adapted to the quick-installation slots 9 at the opening. When installation is required, the upper cable tray 101 is fixed to the top of the wall. Then, the quick-installation extension 10 at one end of the opening of the lower cable tray 102 is aligned with the quick-installation slot 9 at one end of the cable tray body 1, and then the quick-installation extension 10 is pushed into the quick-installation slot 9. After that, the upper cable tray 101 and the lower cable tray 102 are aligned to complete the installation. It should be noted that after the installation is completed, the upper cable tray 101 and the lower cable tray 102 need to be fixed with bolts to prevent the lower cable tray 102 from sliding.

[0033] In this embodiment, when the handle 8 is dragged to move multiple cables, the dragging of the handle 8 may press on the side of the lower cable tray 102, causing the side of the lower cable tray 102 to dent inward, resulting in a certain deformation of the lower cable tray 102. To prevent the deformation of the lower cable tray 102, multiple triangular support members 11 are fixed between the two sides of the inner wall of the lower cable tray 102 and the bottom. The multiple triangular support members 11 prevent the inner wall of the lower cable tray 102 from denting inward. At the same time, the lower cable tray 102 is not easy to deform during transportation or carrying.

[0034] In this embodiment, after the upper cable tray 101 and the lower cable tray 102 are slidably connected and installed, they need to be fixed with bolts. However, this requires drilling first, and bolts can be used to fix them after drilling. Therefore, drilling tools are required, which increases the difficulty of installation. To reduce the difficulty of installation, multiple bolt holes 12 are provided at the quick-installation slot 9 of the upper cable tray 101 and the quick-installation extension 10 of the lower cable tray 102. When the upper cable tray 101 and the lower cable tray 102 are aligned, the bolt holes 12 overlap. After the upper cable tray 101 and the lower cable tray 102 are slidably connected and installed, bolts can be inserted along the bolt holes 12 to fix the upper cable tray 101 and the lower cable tray 102, thus reducing the difficulty of installation.

[0035] In this embodiment, after the cable feeding is completed, it is generally necessary to limit the cable and maintain a certain distance between the cables. The purpose is to prevent multiple cables from sticking together, generating high temperatures or posing safety hazards. Therefore, it is necessary to add other methods for limiting the cables. The presence of the cable puller 4 restricts the operator's operation. However, it can be found that when the cable passes through the cable pull hole 5 and the cable puller 4 rotates 90°, the cable plastic layer has a certain elasticity, at which point the cable puller 4 can play a limiting role. Afterwards, the multiple cables can be adjusted to maintain a certain distance. To ensure that the cable puller 4 can continuously maintain the limiting role, a rectangular limiting block 13 is provided at the connection between the handle 8 and the connecting rod 7, and the limiting block 13 is fixed to the handle. The limit block 13 has a movable hole 14, and the connecting rod 7 is inserted and slidably connected to the movable hole 14. At the same time, in order to make the connecting rod 7 rotate together when the limit block 13 rotates, a rack 15 is fixed on the inner wall of the part of the connecting rod 7 that extends into the movable hole 14. Multiple racks 16 that are adapted to the rack 15 are fixed on the inner wall of the movable hole 14 of the limit block 13. Finally, a rectangular limit groove 17 is opened downward at one end of the sliding track 2 and the sliding groove 3. When it is necessary to limit, pull the handle 8 to press down the limit block 13 and move the limit block 13 into the limit groove 17. At this time, the inner walls on both sides of the rectangular limit groove 17 can limit the rotation of the limit block 13, thereby enabling the rotation of the wire member 4.

[0036] In this embodiment, due to the sliding groove 3, an opening is left on one side of the cable tray body 1, which reduces the fire resistance and dust resistance. To avoid reducing the fire resistance of the cable tray body 1, a shielding member 18 is provided on the side of the cable tray body 1 located in the sliding groove 3. A limiting slide rail 19 is fixed on the cable tray body 1. Both ends of the shielding member 18 are embedded in the limiting slide rail 19 and slidably connected to the limiting slide rail 19. The shielding member 18 is provided with a sliding opening 20 that matches the sliding groove 3. In this way, when the limiting block 13 moves down into the limiting groove 17, the limiting member drives the shielding member 18 to move down. The bottom of the shielding member 18 covers the sliding groove 3, and the cable tray body 1 blocks the sliding opening 20 of the shielding member 18, thereby closing the sliding groove 3 and ensuring the fire resistance.

[0037] Working principle:

[0038] S1. During installation, fix the upper cable tray 101 to the top of the wall, align the quick-release extension 10 of the lower cable tray 102 with the quick-release slot 9 of the upper cable tray 101 and push it in. After alignment, use bolts to fix the upper cable tray 101 and the lower cable tray 102 through the preset bolt holes 12 to prevent the lower cable tray 102 from sliding.

[0039] S2. During the cable feeding process, insert one end of multiple cables into the cable pulling hole 5 of the cable pulling component 4. Then, rotate the cable pulling component 4 by using the handle 8 to bend or wrap the cables around the cable pulling component 4. Use the cable's elasticity to resist the cable pulling component 4 to lock the cables. Next, drag the handle 8. Since the slide rod 6 at one end of the cable pulling component 4 slides in the sliding track 2 and the connecting rod 7 at the other end slides in the sliding groove 3, the cable pulling component 4 and the locked or wrapped cables move along the sliding track 2 and the sliding groove 3, dragging multiple cables from one end of the cable tray body 1 to the other end.

[0040] S3. When cables need to be restricted, the cable tie 4 and the cable tray body 1 are in a vertical position. Then, by rotating the handle 8, the cable tie 4 is rotated 90°, keeping the cable tie 4 in a limited position parallel to the cable tray body 1. Then, the handle 8 is pulled to move the limiting block 13 down into the limiting groove 17. The limiting groove 17 restricts the rotation of the limiting block 13, thereby restricting the rotation of the cable tie 4. Finally, the limiting operation can be completed by adjusting the spacing between the cables. At the same time, when the limiting block 13 moves down, it moves the blocking part 18 down to cover the sliding groove 3, sealing the sliding groove 3 to ensure fire resistance.
