Description

Technical Field

[0001] This utility model relates to the field of building cable tray technology, and in particular to a building cable tray with fireproof function. Background Technology

[0002] Cable trays are systems with a continuous, rigid structure, consisting of trays, straight sections of ladders, bends, accessories, and supports, used to support cables. Their main function is to provide a safe and orderly laying channel for cables, making cable arrangements neater and more standardized, facilitating installation, maintenance, and management. They also provide a certain degree of protection for the cables, preventing damage from external factors.

[0003] In the existing technology, most cable trays are designed as integrated units or with hinged top covers, as shown in the technical solution provided by Chinese Utility Model Patent CN220358721 U. Moreover, the edges of existing cable trays are provided with wavy and strip structures. However, wavy and strip structures perform poorly in terms of energy absorption. Specifically, the curvature changes of wavy structures can easily lead to stress concentration, while the simple shape of strip structures cannot provide enough deformation space to absorb impact energy, thus affecting the strength of the cable tray and failing to protect the internal cables well when encountering impact.

[0004] Secondly, the lack of cable management channels inside the cable trays leads to a relatively messy wiring situation. When laying a large number of cables in the cable trays, the absence of channels for sorting and organizing them causes cables to easily become tangled and cross each other, affecting not only the aesthetics of the wiring but, more importantly, greatly hindering cable maintenance and repair. When repairing or replacing a specific cable, a significant amount of time is often spent locating and separating it, reducing work efficiency. Furthermore, the haphazard accumulation of cables impedes heat dissipation, easily leading to overheating and affecting the cable's lifespan and safety. Therefore, we propose a fire-resistant building cable tray. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a fireproof building cable tray to solve the technical problems of high occupancy rate and low structural strength and stability of cable trays during use.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a fireproof building cable tray is designed, comprising a base plate and a top cover. Two side plates are fixedly connected to the top left and right sides of the base plate, and an accommodating space is formed between the two side plates. The top cover is fitted between the two side plates and slides along the length of the side plates. A cable management device located in the accommodating space is fixedly connected to the top of the base plate for guiding and organizing the cables.

[0007] Preferably, the cable management device includes a cable management base and springs. The cable management base has cable grooves evenly distributed in the middle. Springs are provided inside the cable grooves. One end of the spring is fixedly connected to the inside of the cable groove, and the other end is slidably engaged with the inside of the cable groove. Two sets of springs are correspondingly distributed inside the three sets of cable grooves.

[0008] Preferably, the top of the two side plates is provided with inclined grooves, and both ends of the top cover are fixedly connected with inclined plates facing the inclined grooves, and the inclined plates are embedded in the inclined grooves to guide the sliding of the top cover.

[0009] Preferably, the two side plates have several side heat dissipation holes arranged in a straight line on opposite sides, and the bottom plate has bottom heat dissipation holes evenly distributed on the bottom.

[0010] Preferably, the top cover has through holes on both the left and right sides, and the top of the two side plates has threaded holes; and the threaded holes and through holes are distributed in a corresponding manner, with four sets of threaded holes.

[0011] Preferably, the reinforcing structure is composed of hexagonal polygonal plates, and the polygonal plates are distributed in a honeycomb pattern on the surface of the side plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model features a reinforcing structure on the side plate, enhancing the overall structural strength of the cable tray and effectively absorbing and dispersing impact energy, thus improving its impact resistance. When subjected to impact, it dissipates a significant amount of impact energy through its own deformation. Specifically, under compression or impact, the reinforcing structure sequentially undergoes elastic bending, plastic yielding, and cavity collapse, effectively absorbing and dispersing impact energy, reducing direct impact on internal cables, thereby better protecting the internal cables and extending their service life.

[0014] 2. In this utility model, by setting a cable management device at the bottom of the cable tray, the cable laying inside the cable tray is more neat and orderly, which is also conducive to cable inspection and maintenance. Furthermore, by setting a spring piece inside the cable trough, the elastic force of the spring piece can better fix the cable inside the cable trough and play a certain buffering role, reducing the risk of cable damage, thus solving the problem of cable fixing and positioning.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] A fire-resistant building cable tray, see [link / reference] Figures 1 to 5The cable tray includes a base plate 1 and a top cover 3. Two side plates 2 are fixedly connected to the top left and right sides of the base plate 1, forming a receiving space between them. The top cover 3 is fitted between the two side plates 2 and slides along the length of the side plates 2. A cable management device 10 located within the receiving space is fixedly connected to the top of the base plate 1 for guiding and organizing cables. The outer walls of both side plates 2 are provided with reinforcing structures 7 to improve their strength. This invention improves upon existing building cable trays by providing inclined grooves 4 at the top of the two side plates 2 and inclined plates 5 at the bottom of the top cover 3. This allows the top cover 3 to move within the inclined grooves 4, improving space utilization, ease of operation, and work efficiency. The reinforcing structures 7 on the side plates 2 enhance the overall structural strength of the cable tray, making it more stable during use. The reinforcing structures 7 also increase the contact area between the cable tray and air, which helps reduce the operating temperature of the cables, improves their current carrying capacity and performance, and solves the problems of structural deformation and stability.

[0023] Specifically, such as Figure 2 and Figure 5 As shown, the cable management device 10 includes a cable management base and spring pieces 12. Cable grooves 11 are evenly distributed in the center of the cable management base. Spring pieces 12 are installed inside the cable grooves 11, with one end of each spring piece 12 fixedly connected to the inside of the cable groove 11 and the other end slidingly engaged with it. Two sets of spring pieces 12 are correspondingly distributed inside the three sets of cable grooves 11. In this invention, the spring pieces 12 installed inside the cable grooves 11 have elasticity, which can better fix the cable inside the cable grooves 11, and the spring pieces 12 can also play a certain buffering role, reducing the risk of cable damage.

[0024] Furthermore, the tops of the two side plates 2 are respectively provided with inclined grooves 4, and both ends of the top cover 3 are fixedly connected to inclined plates 5 facing the inclined grooves 4, with the inclined plates embedded in the inclined grooves 4 to guide the sliding of the top cover 3. By setting the inclined grooves 4 and inclined plates 5, this utility model allows the top cover 3 to be opened and closed simply by sliding along the inclined grooves 4, which is convenient to operate, helps to save time and labor costs, and improves work efficiency.

[0025] It is worth noting that several side heat dissipation holes 9 are arranged in a straight line on the opposite sides of both side plates 2, and bottom heat dissipation holes 8 are evenly distributed on the bottom of the base plate 1. When the utility model is installed and in use, the side heat dissipation holes 9 and bottom heat dissipation holes 8 can enhance air convection. Hot air has the characteristic of rising, and the heated air inside the cable tray will gradually be discharged upward through the side heat dissipation holes, while the relatively cool air outside will flow into the cable tray quickly from the bottom heat dissipation holes under the action of pressure difference, promoting air circulation inside and outside the cable tray and effectively reducing the temperature inside the cable tray.

[0026] It is worth noting that the top cover 3 has through holes on both its left and right sides, and the tops of the two side plates 2 each have threaded holes 6. Furthermore, the threaded holes 6 correspond to the through holes, with four sets of threaded holes 6. This facilitates the fixing of the top cover 3 to the two side plates after the top cover 3 is slidably installed. During installation, the top cover 3 is placed over the cable tray, ensuring precise alignment between the top cover 3 and the threaded holes 6 on the two side plates 2. Then, suitable high-strength bolts are selected and tightened through these pre-drilled threaded holes using professional installation tools. The bolts are gradually screwed into the threaded holes, generating a strong tightening force that firmly locks the top cover and the two side plates together, enhancing the stability of the building's cable tray.

[0027] It is worth noting that the reinforcing structure 7 is composed of hexagonal polygonal plates, which are distributed in a honeycomb pattern on the surface of the side plate 2. A fire-resistant layer is also provided on the inner wall of the cable tray. By incorporating the reinforcing structure 7 into the side plate 2, the overall structural strength of the cable tray is improved, stability is enhanced, and auxiliary heat dissipation is provided. Furthermore, the hexagonal or rhomboid cell shape of the honeycomb structure effectively absorbs and disperses impact energy, improving the impact resistance of the cable tray. This allows the cable tray to better protect the internal cables when subjected to external impacts or vibrations, extending the cable's service life. In addition, the fire-resistant layer effectively blocks flames and heat, reducing the burning rate of the cable insulation and sheath.

[0028] It should be noted that honeycomb structures have a high energy absorption capacity, dissipating a large amount of impact energy through their own deformation when subjected to impact. When the hexagonal lattice of this structure is compressed or impacted, it will successively undergo elastic bending, plastic yielding, and cavity collapse, thereby effectively absorbing and dispersing impact energy and reducing direct impact on the internal cables.

[0029] Furthermore, the hexagonal or rhomboid cell shape of a honeycomb structure can effectively distribute and withstand external forces from all directions, preventing the side panels from deforming or being damaged under heavy pressure or impact. Wavy and strip structures are relatively weaker in terms of structural stability.

[0030] Working principle: When this utility model is in use, the inclined plate 5 moves inside the inclined groove 4, so that the top cover 3 can slide inside the inclined groove 4. It can be opened and closed quickly to facilitate operation by the staff. The cable is passed through the inside of the cable groove 11. The cable groove 11 is provided with a spring piece 12. The elasticity of the spring piece is used to fix the cable inside the cable groove 11, preventing the cable from shaking randomly inside the cable tray.

[0031] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
