Description

Technical Field

[0001] This invention relates to the field of cable tray technology, specifically a high-strength adjustable cable tray for communication equipment rooms. Background Technology

[0002] As the core hub for data processing and forwarding in communication networks, communication equipment rooms deploy various critical communication devices such as switches, routers, servers, and firewalls. These devices require numerous fiber optic cables and twisted-pair cables to interconnect signals and data. To ensure neat cable routing and facilitate future maintenance and troubleshooting, ceiling-mounted open cable trays are commonly used in equipment rooms. These trays are primarily composed of two parallel main beams and several crossbeams, suspended from the ceiling by hangers. This design effectively utilizes upper space and allows for layered layouts of cables and floor-mounted equipment.

[0003] Due to the open design of the cable trays, dust easily accumulates on the surface of the cables in the equipment room, forming a heat insulation layer. This not only hinders the dissipation of heat during data transmission, causing local temperature increases, but also accelerates the aging process of the cable sheath, reducing its insulation performance and mechanical strength. Under long-term operation, this can easily lead to cable short circuits, signal attenuation, and other faults, seriously threatening the stable operation of the communication system.

[0004] Currently, cleaning the surface of cables is often done manually with a hand-held brush or a hand-held portable vacuum cleaner. However, since cable trays are usually ceiling-mounted, workers need to climb up to clean the cables, which poses a risk of falling. In addition, the mobility and operational flexibility of the equipment are limited, resulting in low cleaning efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a high-strength adjustable cable tray for communication equipment rooms to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-strength adjustable cable tray for a communication equipment room includes two main beams, two fixed crossbeams, and several movable crossbeams. The two main beams are parallel to each other, and the two fixed crossbeams are respectively positioned between the two ends of the two main beams. The several movable crossbeams are located between the two fixed crossbeams, and adjacent movable crossbeams are fixedly connected by a linkage rod. Each main beam has a movable groove, and a movable block is slidably disposed within the movable groove. The movable blocks inside the two main beams are connected to both ends of one of the movable crossbeams. Limit blocks are provided at both ends of the remaining movable crossbeams. A limit groove is provided at the bottom of the main beam to slide with the limit block. The tray also includes:

[0008] A dust removal assembly, which is mounted on a movable crossbeam, is used to clean the cables on the cable tray.

[0009] A drive assembly is disposed between two main beams and connected to a movable crossbeam, used to drive the movable crossbeam to move and clean the cables.

[0010] A controllable flow guiding component is installed inside the main beam and connected to the movable block. While the drive component drives the movable crossbeam to move, the movable block slides synchronously along the movable groove, thereby driving the controllable flow guiding component to perform a suction action and collect the dust-laden gas raised by the dust removal component.

[0011] A filter assembly is disposed at both ends of the main beam and connected to a controllable flow guiding assembly for filtering dust in the dust-laden gas.

[0012] A limiting component is provided on a fixed crossbeam and a movable crossbeam to limit the placement of cables.

[0013] A positioning component is disposed on a limiting component and is used to fix the limiting component.

[0014] A hoisting assembly is installed on the top surface of the two main beams and is used to connect the top of the machine room and the main beams.

[0015] As a preferred embodiment of the present invention, the dust removal assembly includes a mounting base. One end of the fixed crossbeam and the movable crossbeam are each equipped with a mounting base, and the other end is equipped with a stop block. A rotating shaft is rotatably mounted on the mounting base, and a rotating frame is fixedly connected to the rotating shaft. Brushes are provided on both sides of the rotating frame.

[0016] As a preferred embodiment of the present invention, the drive assembly includes a mounting frame installed at the bottom of two main beams, an electric push rod mounted on the mounting frame, and a push plate connected to one of the movable crossbeams mounted on the telescopic end of the electric push rod.

[0017] As a preferred embodiment of the present invention, the controllable flow guiding assembly includes flow guiding cavities symmetrically distributed on both sides of the main beam, with flow guiding plates slidably disposed within the flow guiding cavities. The flow guiding plates are fixedly connected to the movable block via connecting rods. An exhaust pipe communicating with the flow guiding cavities is provided on the side wall of the main beam, and a flow guiding pipe is provided on the top of the main beam. Several flow guiding ports, spaced apart and communicating with the flow guiding pipes, are provided on the top side of the two main beams. Filter cavities are provided at both ends of the main beam. The top of the filter cavity is connected to the flow guiding pipe via an inlet air pipe, and the bottom of the filter cavity is connected to the flow guiding cavity via a rear inlet air pipe.

[0018] As a preferred embodiment of the present invention, the filter assembly includes a filter box that matches the filter chamber. The top and bottom of the filter box are provided with openings, and a dust filter plate is provided inside the filter box. A cover plate is provided on the outer wall of the filter box, and a sealing groove that cooperates with the cover plate is opened on the main beam outside the filter chamber.

[0020] As a preferred embodiment of the present invention, the positioning component includes a positioning block installed at the bottom of the middle part of the limiting frame. The fixed crossbeam and the movable crossbeam are both provided with positioning grooves that slide with the positioning block. The limiting frame is threaded with a locking bolt that passes through the positioning block. The positioning groove is provided with a locking hole that cooperates with the locking bolt.

[0021] As a preferred embodiment of the present invention, the hoisting assembly includes a plurality of telescopic adjustment rods spaced apart and installed on the top of the main beam, with a hoisting plate installed at the top of the telescopic adjustment rods.

[0022] The present invention has the following advantages: The present invention achieves efficient cleaning of the cable tray surface through several movable crossbeams, cleaning components and drive components; relying on the controller to programmatically control the drive components, periodic cleaning operations can be precisely executed. During the cleaning process, the controllable flow guiding component synchronously generates a continuous and stable negative pressure suction force to quickly adsorb the dust-laden gas raised during cleaning, and the dust is efficiently intercepted and collected by the filter component. The entire cleaning process is completed autonomously without the need for manual operation at height, which not only greatly improves the efficiency and safety of cleaning operations, but also completely avoids the technical limitations of traditional manual cleaning, such as the risk of falling from height, limited equipment movement and insufficient operational flexibility.

[0034] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0035] Please see Figures 1-10A high-strength adjustable cable tray for a communication equipment room includes two main beams 101, two fixed crossbeams 102, and several movable crossbeams 103. The two main beams 101 are parallel to each other, and the two fixed crossbeams 102 are respectively located between the two ends of the two main beams 101. The several movable crossbeams 103 are located between the two fixed crossbeams 102, and adjacent movable crossbeams 103 are fixedly connected by a linkage rod 104. A movable groove 105 is formed inside each main beam 101, and a movable block 106 is slidably arranged inside the movable groove 105. The movable blocks 106 inside the two main beams 101 are connected to both ends of one of the movable crossbeams 103. Limiting blocks 108 are provided at both ends of the remaining movable crossbeams 103. A limiting groove 107 is formed at the bottom of each main beam 101, which slides with the limiting block 108. The cable tray also includes:

[0036] The dust removal component 4 is mounted on the movable crossbeam 103 and is used to clean the cables on the cable tray.

[0037] The drive assembly 5 is disposed between the two main beams 101 and connected to the movable crossbeam 103, and is used to drive the movable crossbeam 103 to move so as to achieve the movement and cleaning of the cable.

[0038] Controllable flow guiding component 6 is installed inside the main beam 101 and connected to the movable block 106. While the driving component 5 drives the movable crossbeam 103 to move, the movable block 106 will slide along the movable groove 105 simultaneously, thereby driving the controllable flow guiding component 6 to perform a suction action and collect the dust-laden gas raised by the dust removal component 4.

[0039] The filter assembly 7 is disposed at both ends of the main beam 101 and connected to the controllable flow guiding assembly 6, and is used to filter dust in the dust-laden gas.

[0040] Limiting component 2, which is disposed on the fixed crossbeam 102 and the movable crossbeam 103, is used to separate and limit the placement of the cable;

[0041] Positioning component 3 is disposed on limiting component 2 and is used to fix limiting component 2;

[0042] The hoisting assembly 8 is installed on the top surface of the two main beams 101 and is used to connect the top of the machine room and the main beams 101.

[0043] In one instance of this embodiment, please refer to Figures 9-10The dust removal assembly 4 includes a mounting base 401. The mounting base 401 is installed at one end of the fixed crossbeam 102 and the movable crossbeam 103, and a stop block 405 is installed at the other end. A rotating shaft 402 is rotatably mounted on the mounting base 401. A rotating frame 403 is fixedly connected to the rotating shaft 402. Brushes 404 are provided on both sides of the rotating frame 403. An inner cavity 406 is opened in the mounting base 401. A torsion spring 407 connected to the rotating shaft 402 is provided in the inner cavity 406.

[0044] Due to the presence of the torsion spring 407, the rotating shaft 402 is subjected to torsional elastic force, causing the rotating frame 403 to press against the stop block 405 under normal conditions. At this time, the rotating frame 403 and the movable crossbeam 103 are basically parallel. The brushes 404 set on both sides of the rotating frame 403 will cover the surface of the laid cable, so that the dust on the cable can be moved and cleaned.

[0045] Since the rotating frame 403 can rotate around the rotating shaft 402, it can be moved to a vertical position during cable laying, making it easier to place the cable on the movable crossbeam 103. After the cable is placed and separated and limited by the limiting component 2 and the positioning component 3, the rotating frame 403 is released. Under the action of the torsion spring 407, the rotating shaft 402 will drive the rotating frame 403 to rotate until it contacts the stop block 405, completing the reset operation, so that the dust removal component 4 contacts the placed cable, making it convenient to clean the dust.

[0046] In one instance of this embodiment, please refer to Figure 7 The drive assembly 5 includes a mounting bracket 501 installed at the bottom of the two main beams 101. An electric push rod 502 is installed on the mounting bracket 501. The telescopic end of the electric push rod 502 is equipped with a push plate 503 connected to one of the movable crossbeams 103.

[0047] In order to remotely clean the cables, the electric push rod 502 is controlled by the controller in the computer room. When cleaning, the controller starts the electric push rod 502, which pushes the connected movable crossbeam 103 to move along the main beam 101. The linkage rod 104 can drive the other movable crossbeams 103 to move synchronously. During this process, the cleaning component 4 will clean the dust on the surface of the cable, realizing the mobile cleaning operation.

[0048] In one instance of this embodiment, please refer to Figures 2-5The controllable flow guiding assembly 6 includes flow guiding cavities 601 symmetrically distributed on both sides of the main beam 101. A flow guiding plate 602 is slidably disposed in the flow guiding cavity 601. The flow guiding plate 602 is fixedly connected to the movable block 106 through a connecting rod 603. An exhaust pipe 609 communicating with the flow guiding cavity 601 is opened on the side wall of the main beam 101. A flow guiding pipe 607 is opened on the top of the main beam 101. Several flow guiding ports 608 are spaced apart and communicating with the flow guiding pipe 607 on the top side of the two main beams 101. A filter cavity 605 is opened at both ends of the main beam 101. The top of the filter cavity 605 is connected to the flow guiding pipe 607 through an inlet air pipe 606. The bottom of the filter cavity 605 is connected to the flow guiding cavity 601 through a rear air intake pipe 604.

[0049] Two symmetrically distributed guide chambers 601 are provided within a single main beam 101. During the movement of the movable crossbeam 103 by the drive assembly 5, the movable crossbeam 103 also synchronously drives the movable block 106 to slide along the movable groove 105. As the movable block 106 slides, the two connecting rods 603 on both sides of the movable block 106 also drive the connected guide plates 602 to move within the guide chambers 601. The two guide plates 602 move in the same direction. The front air pipe 606, rear air pipe 604, and exhaust pipe 609 are located at the far end of the two guide chambers 601, allowing one guide plate 602 to discharge air from the guide chamber 601 through the exhaust pipe 609, while the other guide plate 602 discharges air from the front air pipe 606 through the rear air pipe 604. 6. The rear air intake pipe 604 draws in outside air, causing one of the guide chambers 601 to perform an exhaust action and the other guide chamber 601 to perform an intake action. Both the front air intake pipe 606 and the exhaust pipe 609 are equipped with one-way valves. The front air intake pipe 606 can only take in air, and the exhaust pipe 609 can only exhaust air. That is to say, during the reciprocating movement of the movable block 106 along the movable groove 105, the guide port 608 on the guide pipe 607 will provide a continuous and stable negative pressure suction force, which can quickly adsorb the dust-laden gas raised by the sweeping. The dust-laden gas enters the guide pipe 607 through the guide port 608, then enters the filter chamber 605 through the front air intake pipe 606, where the dust-laden gas is filtered, and then enters the guide chamber 601 through the rear air intake pipe 604.

[0050] In one instance of this embodiment, please refer to Figures 4-6 The filter assembly 7 includes a filter box 701 that matches the filter chamber 605. The top and bottom of the filter box 701 are provided with openings 702, and a dust filter plate 703 is provided inside the filter box 701. A cover plate 704 is provided on the outer wall of the filter box 701. The main beam 101 is located outside the filter chamber 605 and has a sealing groove 705 that cooperates with the cover plate 704.

[0051] The dust-laden gas drawn in by the front air pipe 606 enters the filter chamber 605. The filter chamber 605 is pre-placed with a filter box 701 containing a dust filter plate 703. The filter box 701 can be connected to the front air pipe 606 and the rear air pipe 604 through the openings 702 at the top and bottom. This allows the dust-laden gas to be filtered by the dust filter plate 703 and then enter the guide chamber 601 through the rear air pipe 604, thus achieving dust filtration and collection.

[0052] It should be noted that the filter box 701 is engaged with the sealing groove 705 of the main beam 101 through the cover plate 704. The edge of the cover plate 704 is provided with buckles, and the sealing groove 705 is provided with corresponding slots, so as to realize the detachable fixing of the filter box 701. In this way, the filter box 701 can be easily disassembled and cleaned, thereby facilitating continuous cleaning and dust collection of the cables.

[0053] In one instance of this embodiment, please refer to Figure 8 The limiting component 2 includes a limiting frame 201. The bottom of the limiting frame 201 is provided with several spaced upper slots 202. The fixed crossbeam 102 and the movable crossbeam 103 are both provided with lower slots 204 that cooperate with the upper slots 202. A rubber block 203 is provided in the upper slot 202. The rubber block 203 can effectively fill the gap between the upper slot 202 and the lower slot 204 and the cable, thus limiting the movement space of the cable.

[0054] When laying cables on the cable tray, the cables are placed separately on different lower slots 204. Then, the limiting frame 201 is pressed onto the fixed crossbeam 102 or the movable crossbeam 103, so that the upper slot 202 at the bottom of the limiting frame 201 corresponds to the lower slot 204. The upper slot 202 and the lower slot 204 can be used to separate and limit the placement of the cables.

[0055] In one instance of this embodiment, please refer to Figure 8 The positioning component 3 includes a positioning block 302 installed at the bottom of the middle part of the limiting frame 201. The fixed crossbeam 102 and the movable crossbeam 103 are both provided with positioning grooves 301 that slide with the positioning block 302. The limiting frame 201 is threaded with a locking bolt 304 that passes through the positioning block 302. The positioning groove 301 is provided with a locking hole 303 that cooperates with the locking bolt 304.

[0056] During the installation of the limit frame 201, in order to facilitate the correspondence between the upper slot 202 and the lower slot 204, the positioning block 302 of the limit frame 201 is inserted into the positioning groove 301 to limit the upper slot 202, so that the upper slot 202 is directly opposite the lower slot 204. Furthermore, by turning the locking bolt 304, the locking bolt 304 is screwed into the locking hole 303, thereby positioning and fixing the limit frame 201.

[0057] It should be noted that, for the movable crossbeam 103, after the limiting frame 201 is fixed, the upper slot 202, lower slot 204 and rubber block 203 do not lock the cable in place. The cable between the upper slot 202 and lower slot 204 can move along the direction of the main beam 101, which facilitates the cleaning component 4 to move and clean the cable. The limiting frame 201 on the fixed crossbeam 102 will fix the cable.

[0058] In one instance of this embodiment, please refer to Figure 1 The hoisting assembly 8 includes several spaced telescopic adjustment rods 802 installed on the top of the main beam 101. A hoisting plate 801 is installed on the top of the telescopic adjustment rods 802. The hoisting plate 801 is installed on the top of the machine room by bolts and is connected to the main beam 101 by the telescopic adjustment rods 802. The height of the main beam 101 can be adjusted by manual or electric adjustment of the telescopic adjustment rods 802. The specific adjustment method is not limited.

[0059] The present invention achieves the installation of cable trays by fixing two main beams 101 to two fixed crossbeams 102, connecting one of the movable crossbeams 103 connected by several linkage rods 104 to the movable block 106 in the movable groove 105, and connecting the remaining movable crossbeams 103 to the limiting block 108 in the limiting groove 107, and then connecting the top of the computer room and the main beams 101 by the hoisting assembly 8.

[0060] During the cable routing process, several cables are placed separately in the lower slots 204 corresponding to the fixed crossbeam 102 and the movable crossbeam 103. Then, the placed cables are separated and limited by the limiting component 2, so that the cables on the cable rack can be neatly arranged, avoiding the cables from piling up in a mess. In addition, the positioning component 3 can be used to fix the limiting component 2, thus completing the separation and placement of the cables.

[0061] All electrical equipment in this invention is controlled by a controller in the computer room. The specific control method is conventional and will not be described in detail here. When it is necessary to clean the dust on the cable surface, the controller triggers the drive component 5 to move. The drive component 5 drives the movable crossbeam 103 connected to it to move, and drives the other movable crossbeams 103 to move synchronously through the linkage rod 104. During this process, the dust removal components 4 installed on the fixed crossbeam 102 and the movable crossbeam 103 simultaneously clean the cable surface. At the same time, when the movable crossbeam 103 moves, it also drives the movable block 106 to slide along the movable groove 105, and drives the guide plates 602 in the two guide chambers 601 to move synchronously through the connecting rods 603 on both sides. During this process, the two guide chambers 601 form a reverse airflow action. One guide chamber 601 performs an air intake action, while the other guide chamber 601 performs an air intake action. When the exhaust action is performed, the guide chamber 601 on the side of the intake action will generate suction. As the dust removal component 4 moves to clean the dust, the dust-laden gas raised during the cleaning can be drawn in through the guide port 608. The dust-laden gas enters the guide pipe 607 and then enters the filter chamber 605 through the front air pipe 606. After the dust is filtered by the filter component 7, the gas enters the guide chamber 601 through the rear air intake pipe 604. When the movable crossbeam 103 moves in the opposite direction under the action of the drive component 5, the airflow action of the two guide chambers 601 is switched. The guide chamber 601 that originally intakes air begins to exhaust through the exhaust pipe 609, while the guide chamber 601 on the other side begins to perform the intake action. Through this structural design, during the reciprocating movement of the movable crossbeam 103 for dust removal, the guide port 608 can continuously generate negative pressure adsorption on the working area between the two main beams 101, realizing the uninterrupted collection of dust-laden gas. The collected dust-laden gas is filtered and purified through the aforementioned airflow path, and the dust is stably trapped in the filter component 7, thereby significantly improving the dust removal efficiency and dust collection effect.

[0062] The power supply and control of the electrical equipment in this application are all existing technologies and will not be elaborated upon here. The control of each component can be achieved using a PLC controller disclosed in the prior art, and the model and circuit connection of each component are not specifically limited. All electrical equipment involved are existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon.
