Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and more specifically, to an organic polymer anti-corrosion cable tray. Background Technology

[0002] Cable trays, as a crucial support system for power and communication lines in modern buildings and industrial engineering, primarily function to centrally support, protect, and manage various cables, ensuring the standardization, safety, and maintainability of the line layout. Traditional cable trays are mostly made of metal, which, while possessing high mechanical strength, are prone to corrosion, poor insulation, and high maintenance costs during long-term operation, affecting the stable operation of the power system. Therefore, the design of organic polymer anti-corrosion cable trays is essential, enabling them to operate stably for extended periods in extreme environments, significantly extending their service life and reducing total life-cycle costs.

[0003] However, existing organic polymer anti-corrosion cable trays still have many shortcomings and defects in practical applications. First, most existing cable trays use bolts or screws to fix the cover plates, making the installation and disassembly process cumbersome, time-consuming, labor-intensive, and requiring specialized tools, resulting in low on-site construction efficiency. During later maintenance or line adjustments, repeated disassembly and assembly can easily cause thread stripping or component loss, affecting the overall sealing and protection level. Second, most traditional cable trays lack effective cable fixing mechanisms or are only equipped with non-adjustable rigid clamps, which cannot adapt to the laying needs of cables of different diameters. This can easily cause excessive clamping, damaging the cable sheath and affecting the neatness and safety of the wiring.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in related technologies, this utility model proposes an organic polymer anti-corrosion cable tray to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows: Organic polymer anti-corrosion cable tray, comprising: a cover plate; a placement component disposed at the bottom end of the cover plate; a snap-fit ​​mechanism symmetrically disposed on one side of the cover plate for engaging the placement component with the cover plate; and several cable clamping mechanisms disposed inside the placement component.

[0007] Furthermore, to ensure safe cable laying, the placement frame provides a stable structural foundation for the entire cable tray, ensuring the straightness and safety of the cables along the laying path. The placement components include: a placement frame located at the bottom of the cover plate; several through holes at the bottom of the placement frame; lifting lugs located at the four corners of the bottom of the placement frame; a connector located on one side of the placement frame and connected to the cover plate; a connecting plate located on the top of one side of the placement frame and mating with the cover plate; through slots symmetrically located on one side of the connecting plate; first locking slots located at the bottom of both sides of the through slots; and several second locking slots located inside the placement frame and mating with the cable clamping mechanism.

[0008] Furthermore, to achieve rapid closing and opening of the cable tray, the cover plate can be quickly locked with the cooperation of the rotating cylinder. This is simple to operate, provides a secure connection, and effectively prevents dust, moisture, and foreign objects from entering the cable tray, thus improving the protection level. Simultaneously, when maintenance is required, simply pressing and rotating the rotating cylinder easily unlocks the cover plate without tools, greatly facilitating later maintenance and cable inspection, and significantly improving operation and maintenance efficiency. The locking mechanism includes a fixed cylinder that penetrates one side of the cover plate. Inside the fixed cylinder is a first spring, and at the top of the first spring is a rotating cylinder. Inside the first spring is a rotating column that connects to the rotating cylinder and penetrates the bottom of the fixed cylinder. A stop block is located on the outside of the rotating column and at the bottom of the fixed cylinder. A connecting block is located at the bottom of the rotating column. Symmetrically arranged at the top of the connecting block are first locking blocks that cooperate with the placement frame. The bottom of the rotating column is located inside the through groove, and the first locking block is located inside the first locking groove. The connecting block is located at the bottom of the through groove, and the connecting block and the through groove are perpendicular to each other.

[0009] Furthermore, to achieve adaptive adjustment of the cable clamping, the clamping space can be adaptively adjusted under the elastic action of the second spring, accommodating cables of different diameters. This avoids problems of excessive tightness or looseness caused by varying cable thicknesses, effectively protecting the cable sheath from damage. Simultaneously, it ensures the cable is stably fixed within the cable tray, preventing displacement due to vibration or external forces, thus improving the safety and neatness of the cabling. The cable clamping mechanism includes several lower clamping plates installed inside the placement frame, with upper clamping plates at the top of each lower clamping plate that cooperate with it. A number of sliding posts are symmetrically arranged through the top of the upper clamping plate. A second spring is connected to the outer side of the sliding post and the top of the upper clamping plate. The top of the four sets of second springs located at the top of two adjacent sets of upper clamping plates is provided with a connecting rod connected to the sliding post. The two ends of the connecting rod are provided with a sliding groove. A third spring is provided inside the end of the sliding groove away from the inner wall of the placement frame. A locking post is provided inside the end of the third spring near the inner wall of the placement frame and located inside the second locking groove. A limit groove is symmetrically opened at the top of the connecting rod. A moving block connected to the locking post is provided inside the limit groove.

[0010] Furthermore, to extend the service life of the cable trays, the high-temperature resistant and corrosion-resistant layer effectively resists the erosion of harsh environments such as humidity, acids, alkalis, and salt spray, significantly extending the service life of the cable trays, reducing later maintenance and replacement costs, and improving the safety and stability of the cable trays. The structure of the placement rack and the cover plate is the same. The cover plate includes: a high-temperature resistant and corrosion-resistant layer, located at the top of the placement rack, to prevent corrosion of the cable trays; a fiberglass plastic layer, located at the bottom of the high-temperature resistant and corrosion-resistant layer, to provide structural strength and load-bearing capacity for the cable trays; and an organic fire-retardant coating, located at the bottom of the fiberglass plastic layer, to provide fire protection for the cable trays.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model, through the coordinated arrangement of cover plate, placement component, snap-fit ​​mechanism and cable clamping mechanism, can not only achieve straightness and safety of cable laying path, but also effectively resist corrosion from harsh environments such as moisture, acid and alkali, and salt spray, extending the service life of cable tray. It can also quickly open the cable tray without the need for special tools when maintenance is required, which not only ensures the temporary opening needs during cable laying, but also allows for rapid closure after construction, improving overall convenience.

[0012] 2. The locking mechanism allows for quick locking of the cover plate with the help of the rotating cylinder. It is easy to operate, securely connected, and effectively prevents dust, moisture and foreign objects from entering the cable tray, thus improving the protection level. At the same time, when maintenance is required, it can be easily unlocked by simply pressing and rotating the rotating cylinder without the need for tools, which greatly facilitates later maintenance and cable inspection and significantly improves operation and maintenance efficiency.

[0013] 3. The cable clamping mechanism can adaptively adjust the clamping space under the elastic action of the second spring, which can accommodate cables of different diameters and avoid the problem of excessive clamping or loosening caused by different cable thicknesses. It effectively protects the cable sheath from damage and ensures that the cable is stably fixed in the cable tray, preventing displacement caused by vibration or external force, thus improving the safety and neatness of the wiring.

[0023] In one embodiment, the structure of the placement rack 201 and the cover plate 1 is the same. The cover plate 1 includes: a high-temperature resistant and corrosion-resistant layer 101, disposed at the top of the placement rack 201, for preventing corrosion of the cable tray; a glass fiber plastic layer 102, disposed at the bottom of the high-temperature resistant and corrosion-resistant layer 101, for providing structural strength and load-bearing capacity to the cable tray; and an organic fire-retardant coating 103, disposed at the bottom of the glass fiber plastic layer 102, for providing fire protection to the cable tray.

[0024] In addition, it should be noted that the high-temperature resistant anti-corrosion layer 101 mentioned above can be made of materials with excellent thermal stability and chemical inertness, such as polytetrafluoroethylene (PTFE), modified epoxy resin, or polymer alloys, in practical applications. It can effectively resist the performance degradation under high-temperature environment and the erosion of corrosive media such as strong acids, strong alkalis, and salt spray. This high-temperature resistant anti-corrosion layer 101 is existing technology and will not be elaborated on further here.

[0025] In addition, it should be noted that the glass fiber plastic layer 102 mentioned above is usually composed of unsaturated polyester resin or vinyl ester resin and glass fiber in practical applications. It has high strength, low water absorption and good dimensional stability. As a structural reinforcement layer, it significantly improves the overall load-bearing capacity and deformation resistance of the cable tray. The glass fiber plastic layer 102 is existing technology and will not be elaborated on here.

[0026] In addition, it should be noted that the above-mentioned organic fireproof coating 103 is mostly used in intumescent flame retardant coatings or halogen-free flame retardant systems in practical applications. When heated, it can quickly foam to form a dense char layer, which isolates heat and oxygen, delays the spread of flames, and meets the fire resistance requirements of cable trays under fire conditions. This organic fireproof coating 103 is existing technology and will not be elaborated on further here.

[0027] In addition, it should be noted that the aforementioned connector 204 can be a hinge in actual application. This connector 204 is existing technology and will not be elaborated on here.

[0028] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0029] In practical applications, during installation, the operator uses the lifting lugs 203 to install the placement component 2 at the specific location where the cable needs to be laid. Specifically, the organic polymer anti-corrosion cable tray is installed at the desired location using bolts and the lifting lugs. The cable to be laid is then placed on the lower clamping plate 401. The operator then presses the two sets of moving blocks 410, bringing adjacent sets closer together. This compresses the third spring 407, causing the two sets of locking posts 408 to move closer together until both sets of locking posts 408 are fully moved into the sliding groove 406. The upper clamping plate 402 is then aligned with the lower clamping plate 402, and the second locking groove 208 is aligned with the locking posts 408. After releasing the two sets of moving blocks 410, under the elastic recovery action of the third spring 407, the locking post 408 is locked into the interior of the second locking groove 208, and the cable to be laid is clamped between the upper clamping plate 402 and the lower clamping plate 401. At this time, under the squeezing action of the cable to be laid on the upper clamping plate 402, the second spring 404 is compressed, and the upper clamping plate 402 moves upward along the path of the sliding post 403, so that the distance between the upper clamping plate 402 and the lower clamping plate 401 can be adjusted according to the thickness of the cable to be laid. After the cable is laid in the placement component 2, the cover plate 1 is rotated so that the side with the locking mechanism 3 can move to the top of the connecting plate 205, so that the connecting block 306 and the first locking... Block 307 can pass through the through slot 206, and then press down on the rotating cylinder 303. Under the squeezing action of the rotating cylinder 303, the first spring 302 is compressed, causing the rotating column 304 to move downward, so that the connecting block 306 and the first locking block 307 can move completely to the bottom of the through slot 206. Then, the rotating cylinder 303 is rotated ninety degrees, so that the first locking block 307 can be aligned with the first locking groove 207. The rotating cylinder 303 is released, and under the elastic recovery action of the first spring 302, the first locking block 307 is locked into the first locking groove 207, completing the quick engagement of the cover plate 1 and the placement component 2. When it is necessary to inspect the cables inside the placement component 2, the first locking block 307 can be engaged by pressing down on the rotating cylinder 303. Block 307 is no longer engaged in the first engaging slot 207, and the first engaging block 307 is completely removed from the first engaging slot 207. Then, the rotating cylinder 303 is rotated 90 degrees in the opposite direction, so that the connecting block 306 and the first engaging block 307 can be aligned with the through slot 206. Then, the rotating cylinder 303 is released. Under the elastic recovery action of the first spring 302 and the blocking action of the stop block 305, the engaging mechanism 3 returns to its original state. At the same time, the cover plate 1 is no longer engaged with the placement component 2. Rotating the cover plate 1 in the opposite direction allows for the inspection of the cables laid in the placement component 2. Simultaneously, by squeezing the two sets of moving blocks 410, the two adjacent sets of moving blocks 410 are brought closer together, which compresses the third spring 407 and drives the two sets of engaging posts 408 to move closer together.Once both sets of locking posts 408 have fully moved into the slide groove 406, the upper clamping plate 402 can be removed for easy cable inspection by the operator.

[0030] In summary, by utilizing the above-mentioned technical solution of this utility model, through the coordinated arrangement of the cover plate 1, the placement component 2, the locking mechanism 3, and the cable clamping mechanism 4, not only can the straightness and safety of the cable be ensured along the laying path, but it can also effectively resist the corrosion of harsh environments such as humidity, acid and alkali, and salt spray, extending the service life of the cable tray. Furthermore, when maintenance is required, the cable tray can be quickly opened without the need for specific tools, ensuring both temporary opening needs during cable laying and rapid closure after construction, thus improving overall convenience. The locking mechanism 3, with the cooperation of the rotating cylinder 303, can quickly lock the cover plate 1, making operation simple and the connection secure. Effectively prevents dust, moisture, and foreign objects from entering the cable tray, improving the protection level. When maintenance is needed, simply press and rotate the rotating cylinder to easily unlock it, without the need for tools, greatly facilitating later maintenance and cable inspection, and significantly improving operation and maintenance efficiency. Through the cable clamping mechanism 4, the clamping space can be adaptively adjusted under the elastic action of the second spring 404, accommodating cables of different diameters and avoiding problems of excessive tightness or looseness caused by varying cable thicknesses. This effectively protects the cable sheath from damage and ensures stable fixation of the cable within the cable tray, preventing displacement due to vibration or external forces, thus improving the safety and neatness of the cabling.
