Description

Technical Field

[0001] This utility model belongs to the field of electrical conduit cable tray technology, and particularly relates to a fire protection electrical conduit cable tray. Background Technology

[0002] Cable tray installation is a commonly used method. Cable trays are classified into various structures such as trough-type cable trays, tray-type cable trays, ladder-type cable trays, and mesh cable trays, and are composed of supports, brackets, and installation accessories. They can be installed independently or laid on various building (structure) supports and pipe rack supports.

[0003] Existing fire protection electrical conduit cable trays are used by directly laying multiple sets of cables inside the tray. However, during the laying process, it is impossible to classify and organize the cables, which easily leads to the cables crossing and getting mixed together. This causes trouble for subsequent maintenance and repair, and also results in poor performance. Therefore, there is an urgent need for a fire protection electrical conduit cable tray to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a fire-fighting electrical conduit cable tray to solve the problem mentioned in the background art that, during the cable laying process, the inability to classify and organize cables easily leads to cables crossing and mixing together, which causes trouble for subsequent maintenance and repair and results in poor performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fire-fighting electrical conduit tray includes a cable tray with a drive assembly mounted on it, and a sorting and organizing assembly disposed within the cable tray. The sorting and organizing assembly includes:

[0007] The bearing shafts are arranged in an array and rotate between the inner walls of the cable tray to reduce the friction during cable laying.

[0008] Separators, installed on the drive assembly, are used to classify and organize cables;

[0009] The guide shaft, rotatably mounted on both sides of the partition plate, can convert the sliding friction between the cable and the partition plate into rolling friction, thus protecting the cable during installation.

[0010] By adopting the above technical solution, during the cable laying process, the separator plate can be adjusted under the action of the drive component to be at a suitable spacing. Then, the cable is laid through the area separated by the separator plate. At the same time, the combination of the bearing shaft and the guide shaft can transform the original sliding friction into rolling friction. On the one hand, it reduces the friction between the two, making it easier for workers to pull the cable. On the other hand, it can protect the outer wall of the cable, thereby realizing the classification and placement of the cable, which is convenient for subsequent inspection and maintenance.

[0011] Furthermore, the driving component includes:

[0012] The transmission box is fixed to one side wall of the cable tray and is used to protect the transmission components.

[0013] The drive wheel is rotatably mounted inside the transmission box, and its surface is provided with toothed grooves.

[0014] The first driven wheel is rotatably disposed inside the transmission box, and its surface is provided with toothed grooves;

[0015] The second driven wheel is rotatably mounted inside the transmission box, and its surface is provided with toothed grooves.

[0016] By adopting the above technical solution, the driving wheel can drive the first driven wheel and the second driven wheel to rotate synchronously through the synchronous belt, so that they can drive the bidirectional screw to rotate respectively.

[0017] Furthermore, the driving component also includes:

[0018] A timing belt, nested on the driving pulley, the first driven pulley, and the second driven pulley, enables the driving pulley, the first driven pulley, and the second driven pulley to rotate synchronously;

[0019] A drive shaft, fixed to the drive wheel, is used to connect to an external power device to drive the drive wheel to rotate.

[0020] The drive hole is formed on the drive shaft and is an internal hexagonal hole, which can drive the drive wheel to rotate by an external electric hand drill.

[0021] By adopting the above technical solution, the cover plate of the transmission box is removed. At this time, the electric drill is connected to the drive hole on the drive shaft. The electric drill can drive the drive wheel to rotate through the drive shaft, and then drive the first driven wheel and the second driven wheel to rotate through the synchronous belt.

[0022] Furthermore, the driving component also includes:

[0023] Cavities are arrayed and formed at the bottom of the cable tray;

[0024] A bidirectional screw is rotatably mounted in the cavity, and there are three sets of them;

[0025] The screw block is fitted onto the bidirectional screw and matches the specifications of the cavity.

[0026] By adopting the above technical solution, the driving wheel, the first driven wheel, and the second driven wheel respectively drive the three sets of bidirectional screws to rotate synchronously.

[0027] Furthermore, one end of each of the three sets of bidirectional screws is fixedly connected to the driving wheel, the first driven wheel, and the second driven wheel, respectively.

[0028] By adopting the above technical solution, during the rotation of the bidirectional screw, the screw block can be moved under the action of the thread and the cavity.

[0029] Furthermore, the partition plate is fixed to the screw block by screws, and the screw block is slidably connected to the cavity.

[0030] By adopting the above technical solution, the screw block drives the partition plate to move, thereby realizing the automatic adjustment of the position of the partition plate.

[0031] Furthermore, the cable tray has symmetrical connection holes on both sides of its side walls, and a top cover is fixed to the top of the cable tray.

[0032] By adopting the above technical solution, the connection hole facilitates the splicing of the cable tray, and the top cover can seal the top of the cable tray after the cable is laid, thereby protecting the cable.

[0033] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows:

[0034] This invention utilizes a drive assembly and a sorting and placement assembly in conjunction. During cable laying, the separator plates can be adjusted by the drive assembly to maintain a suitable spacing. The cable is then laid through the area separated by the separator plates. Simultaneously, the combination of the bearing shaft and the guide shaft transforms the original sliding friction into rolling friction. This reduces friction between the two, making it easier for workers to pull the cable, and also protects the outer wall of the cable. This achieves the sorting and placement of the cable, facilitating subsequent inspection and maintenance, and resulting in high performance. Attached Figure Description

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0043] like Figure 1 , Figure 2 as well as Figure 3 As shown, a fire-fighting electrical conduit cable tray includes a cable tray 1, a drive assembly 4 installed on the cable tray 1, and a sorting and organizing assembly 5 disposed inside the cable tray 1. The sorting and organizing assembly 5 includes: a bearing shaft 501, which is arranged in an array and rotates between the inner walls of the cable tray 1 to reduce the friction during cable laying; a partition plate 502, which is disposed on the drive assembly 4 and is used to sort and organize the cables; and a guide shaft 503, which is rotatably disposed on both sides of the partition plate 502 and can convert the sliding friction between the cable and the partition plate 502 into rolling friction, thereby protecting the cable during laying.

[0044] The specific steps are as follows:

[0045] During cable laying, the separator 502 can be adjusted under the action of the drive component 4 to achieve a suitable spacing. Then, the cable is laid through the area separated by the separator 502. At the same time, the bearing shaft 501 and the guide shaft 503 can combine to transform the original sliding friction into rolling friction. On the one hand, this reduces the friction between the two, making it easier for workers to pull the cable. On the other hand, it can protect the outer wall of the cable, thereby achieving the classification and placement of the cable, which is convenient for subsequent inspection and maintenance.

[0046] like Figures 1-5 As shown, in one embodiment, the drive assembly 4 includes: a transmission box 401, fixed to one side wall of the cable tray 1, used to protect the transmission components; a drive wheel 404, rotatably disposed within the transmission box 401, with toothed grooves on its surface; a first driven wheel 406, rotatably disposed within the transmission box 401, with toothed grooves on its surface; a second driven wheel 407, rotatably disposed within the transmission box 401, with toothed grooves on its surface; a synchronous belt 405, nested on the drive wheel 404, the first driven wheel 406, and the second driven wheel 407, enabling the drive wheel 404, the first driven wheel 406, and the second driven wheel 407 to rotate synchronously; and a drive shaft 408, fixed to the drive wheel 404. On 04, it is used to connect with external power equipment to drive the drive wheel 404 to rotate; the drive hole 409 is opened on the drive shaft 408 and is an internal hexagonal hole, which can drive the drive wheel 404 to rotate by an external electric hand drill; the cavity 410 is arrayed at the bottom of the cable tray 1; the bidirectional screw 402 is rotatably installed in the cavity 410 and there are three sets; the screw block 403 is sleeved on the bidirectional screw 402 and matches the specifications of the cavity 410. One end of the three sets of bidirectional screws 402 is fixedly connected to the drive wheel 404, the first driven wheel 406 and the second driven wheel 407 respectively. The partition plate 502 is fixed on the screw block 403 by screws. The screw block 403 is slidably connected to the cavity 410.

[0047] The specific steps are as follows:

[0048] When adjusting the position of the partition plate 502, an external hand drill can be connected to the drive hole 409 on the drive shaft 408. The external hand drill drives the drive wheel 404 to rotate, and the drive wheel 404 then drives the first driven wheel 406 and the second driven wheel 407 to rotate through the synchronous belt 405. The three of them then drive the three sets of bidirectional screws 402 to rotate synchronously, thereby causing the screw block 403 to move the partition plate 502 under the action of the thread and the cavity 410, realizing the automatic adjustment of the position of the partition plate 502 with high adjustment efficiency.

[0049] like Figure 1 and Figure 2 As shown, in one embodiment, the cable tray 1 has symmetrical connection holes 3 on both sides of its side walls, and a top cover 2 is fixed to the top of the cable tray 1.

[0050] The specific steps are as follows:

[0051] The connection hole 3 facilitates the splicing of the cable tray 1, and the top cover 2 can seal the top of the cable tray 1 after the cable is laid, thereby protecting the cable.

[0052] In summary, the working principle of this fire-fighting electrical conduit cable tray is as follows: First, the cable tray 1 is erected and assembled through the connection holes 3. After erection, when laying cables, an external hand drill is connected to the drive hole 409 on the drive shaft 408. The external hand drill drives the drive wheel 404 to rotate, and the drive wheel 404 then drives the first driven wheel 406 and the second driven wheel 407 to rotate through the synchronous belt 405. The three of them then drive the three sets of bidirectional screws 402 to rotate synchronously, thereby causing the screw block 403 to move the partition plate 502 under the action of the thread and the cavity 410, realizing the automatic adjustment of the position of the partition plate 502. After adjustment, the cable is laid through the area separated by the partition plate 502. At the same time, the combination of the bearing shaft 501 and the guide shaft 503 can transform the original sliding friction into rolling friction. On the one hand, it reduces the friction between the two, making it easier for workers to pull the cable. On the other hand, it can protect the outer wall of the cable, thereby realizing the classification and placement of the cable, which is convenient for subsequent inspection and maintenance, and has high performance.

[0053] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
