Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, and more particularly to a flame-retardant cable bridge. Background Art

[0002] As modern society becomes increasingly dependent on electricity and communications, the laying and management of cables has become crucial. In various buildings, industrial facilities, and public infrastructure, a large number of cables need to be laid out and transmitted safely and orderly. In order to cope with the risk of fire, flame-retardant cable trays have come into being. However, the cable trays currently on the market are installed by combining multiple bolts and nuts. This method results in a relatively low installation speed for the cable trays. At the same time, the assembly process of bolts and nuts is relatively cumbersome, making the installation and disassembly of the cable trays time-consuming and labor-intensive.

[0003] In response to the above-mentioned problems, regarding the technical problem of time-consuming and labor-intensive installation and disassembly of cable trays currently on the market, after extensive searching, a flame-retardant cable tray with patent number CN216312576U was found, which specifically relates to the technical field of cable trays, including an upper plate of a cable tray, a connecting plate provided at the bottom of the upper plate of the cable tray, a through hole provided on one side surface of the connecting plate, a disassembly mechanism provided at the bottom of the upper plate of the cable tray, and a card slot provided on the surface of the lower plate of the cable tray, a fixing spring fixedly provided at the bottom of the inner wall of the card slot, and a support plate provided on the top of the fixing spring. By providing a disassembly mechanism, the utility model can more simply and conveniently disassemble the upper and lower plates of the cable tray, and the installation is simple and fast, solving the problem that traditional cable trays need to be fixed and disassembled by multiple bolts and nuts, greatly reducing the disassembly and installation time, thereby improving work efficiency; however, the technical solution provided by this patent has the following problems:

[0004] (1) According to the description of the patent CN216312576U, when disassembling and assembling the cable tray, the elasticity of the spring is completely relied upon to realize the movement of other components. However, in actual use, if the elasticity of the spring is weakened due to long-term use, the support plate may not be able to bounce up smoothly, or the movable clamping rod may not be able to be completely pulled out of the connecting groove, thereby affecting the normal disassembly of the cable tray.

[0005] (2) During the use of existing flame-retardant cable trays, due to the lack of reasonable separation and fixing devices inside the main body of the tray, a large number of cables are piled up in a disorderly manner, which easily causes the problem of cable knotting. This situation will reduce the air circulation space between the cables, making it difficult for heat to dissipate. In this way, the operating temperature of the cable will increase, thereby accelerating the aging of the cable insulation layer and reducing the service life of the cable.

[0006] The utility model can quickly disassemble and assemble the cable tray without relying on the elasticity of the spring, preventing the spring from weakening due to long-term use and affecting the normal disassembly of the cable tray; and can effectively organize the cables into layers to avoid the cables from being entangled and chaotic, thereby increasing the air circulation space between the cables, reducing the situation where the operating temperature of the cables increases due to the difficulty in dissipating heat, accelerating the aging of the insulation layer, and improving the service life of the cables.

[0024] The following is a combination of the appended examples of the present invention Figure 1-Figure 4 , clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0025] See also Figure 1-4The jacks 12 are provided at the bottom of the cable tray 1 and the top of the cable tray 2 are provided at the top of the cable tray 1, so as to form a space for accommodating and protecting the cables. A fixing assembly is provided between the lower plate 1 of the cable tray and the upper plate 2 of the cable tray, and a layered assembly is provided inside the lower plate 1 of the cable tray; the fixing assembly includes a card slot 3 opened at the left and right ends of the lower plate 1 of the cable tray and the upper plate 2 of the cable tray, and the card block 4 is slidably connected to the inside of the card slot 3. The card block 4 slides in the card slot 3 to achieve the fixed connection between the upper plate 2 of the cable tray and the lower plate 1 of the cable tray, ensuring the integrity and stability of the bridge structure. The plug-in plates 12 are provided at both ends below the upper plate 2 of the cable tray, and the slots 13 are provided on the upper end surface of the lower plate 1 of the cable tray; the plug-in plates 12 are inserted into the slots 13 to further enhance the firmness and accuracy of the connection between the upper plate 2 of the cable tray and the lower plate 1 of the cable tray The placement groove 6 is opened on the inner surface of the lower plate 1 of the frame, and the socket 7 is opened on one side of the placement groove 6. The placement block 9 is clamped inside the placement groove 6, and the placement block 9 is clamped in the placement groove 6, which provides a basis for subsequent fixing and layering operations. The insertion rod 14 is inserted into the socket 7 to fix the position of the placement block 9, thereby ensuring the stability of the layered structure. The inner groove 15 is opened inside the placement block 9, and the slide groove 16 is opened at both ends of the inner groove 15. The slider 11 slides inside the slide groove 16. The movable plate 17 is fixedly connected between the sliders 11, and the slide groove 16 provides a sliding track for the slider 11. The slider 11 is connected to the movable plate 17, so that the movable plate 17 can move smoothly in a specific direction, thereby driving the insertion rod 14 to realize the corresponding action. The electric push rod 10 is connected to the left side of the movable plate 17. The insertion rod 14 is set below the electric push rod 10, and the arc block 8 is set at the upper end of the placement block 9. The arc block 8 is located at the upper end of the placement block 9, and they work together to layer and fix the cables.

[0026] In the embodiment of the present utility model, card slots 3 are provided on the left and right end surfaces of the lower plate 1 of the cable tray and the upper plate 2 of the cable tray, which provide space and tracks for the installation and sliding of the card block 4, so that the card block 4 can move along a predetermined path, thereby realizing the fixing or loosening operation of the upper and lower plates. The card slots 3 and the connection between the lower plate 1 of the cable tray and the upper plate 2 of the cable tray are centrally symmetrically arranged. This symmetrical distribution can make the sliding of the card block 4 in the card slots 3 smoother and the force more evenly distributed, thereby ensuring the stability and reliability of the fixation. At the same time, the symmetrical setting also makes the appearance of the cable tray more beautiful and the structure more regular. The card block 4 is slidably connected to the inside of the card slot 3, and the card block 4 can slide freely in the card slot 3 to achieve combination or separation with the card slot 3, thereby completing the fixing or disassembly operation of the upper and lower plates of the cable tray. The sliding connection method is simple, convenient and easy to operate. The card block 4 is U-shaped, and the U-shaped shape can better wrap and clamp the card slot 3, increase the contact area between the card block 4 and the card slot 3, and improve the firmness of the fixation. The handle 5 is fixedly installed on the outer surface of the card block 4, which is convenient for the operator to manually push and pull the card block 4 to slide in the card slot 3, thereby performing installation or disassembly operations, improving the convenience and efficiency of operation. These positional relationships cooperate with each other, so that the card block 4 can effectively fix or disassemble the lower plate 1 and the upper plate 2 of the cable tray, which is easy to operate and reliable to fix.

[0027] In the embodiment of the present invention, slots 13 are respectively provided at both ends of the upper surface of the lower plate 1 of the cable tray, providing a position for the plug-in board 12 to be inserted, determining the installation position and direction of the plug-in board 12, and the plug-in board 12 is inserted and connected inside the slot 13. This insertion connection method enhances the accuracy and stability of the connection between the upper plate 2 of the cable tray and the lower plate 1 of the cable tray. The cooperation between the plug-in board 12 and the slot 13 can limit the relative movement of the upper plate 2 of the cable tray and the lower plate 1 of the cable tray in the horizontal direction, and prevent misalignment. The plug-in board 12 is fixedly connected to the lower end surface of the upper plate 2 of the cable tray, ensuring that the plug-in board 12 can be moved and installed together with the upper plate 2 of the cable tray, so that the upper plate 2 of the cable tray and the plug-in board 12 become a whole, and are connected and fixed to the lower plate 1 of the cable tray together. These positional relationships interact with each other, making the connection between the upper plate 2 of the cable tray and the lower plate 1 of the cable tray more stable and accurate, and improving the overall structural strength and stability of the cable tray.

[0028] In the embodiment of the present utility model, a plurality of placement grooves 6 are provided on the inner surface of the lower plate 1 of the cable tray, which provide a position for the installation of the placement blocks 9, so that the layered components can be installed on the lower plate 1 of the cable tray. The placement grooves 6 are evenly arranged at equal intervals. This even arrangement can make the layered arrangement of the cables in the cable tray more regular and orderly, and facilitate the management and maintenance of the cables. The equal spacing can ensure that the weight of the cables borne by each layer is relatively uniform, avoiding excessive local stress. The inner surface of one end of the placement grooves 6 is provided with a socket 7, which is used to cooperate with the insertion rod 14. When the insertion rod 14 is inserted into the socket 7, the placement block 9 placed in the placement groove 6 can be fixed to ensure the stability of the layered structure. The setting of these positional relationships helps to realize the layered function of the cable tray, improve the rationality and stability of cable laying, and facilitate subsequent maintenance and management.

[0029] In the embodiment of the present invention, the placement blocks 9 are respectively clamped inside the placement groove 6, and the outer wall of the placement block 9 is tightly fitted with the inner wall of the placement groove 6. The clamping method enables the placement block 9 to be stably installed in the placement groove 6 and is not easy to fall off or shift. The tight fit ensures that there is no gap between the placement block 9 and the placement groove 6, enhances the stability of the structure, and reduces the shaking and looseness that may occur during use. The placement block 9 is provided with an inner groove 15, which provides installation space for the internal moving plate 17, slider 11, electric push rod 10 and other components, making the structure of the layered component more compact. The upper end of the placement block 9 is fixedly connected with an arc block 8, which is arc-shaped and symmetrically arranged on the upper end surface of the placement block 9. The arc-shaped arc block 8 can better fit the shape of the cable, effectively limit and fix the cable, and prevent the cable from sliding from the layered position. The symmetrical arrangement makes the support and fixation of the cable more balanced, ensuring the stability of the cable in the layered position. The design of these positional relationships enables the layered component to effectively fix the cable in layers, improving the performance and safety of the cable tray.

[0030] In the embodiment of the present utility model, sliding grooves 16 are respectively provided at the upper and lower ends of the inner groove 15, which provide tracks and guides for the sliding of the slider 11 and determine the movement path of the slider 11. The slider 11 is slidably connected inside the sliding groove 16, and the slider 11 can slide smoothly in the sliding groove 16, thereby driving the movable plate 17 connected thereto to move. The movable plate 17 is fixedly connected between the sliders 11 to ensure that the movement of the slider 11 can synchronously drive the movable plate 17 to move, making the movement of the movable plate 17 more stable and consistent. The movable plate 17 is slidably connected to the upper and lower end surfaces of the inner groove 15. This sliding connection method further limits the freedom of movement of the movable plate 17, so that it can only move along the length direction of the inner groove 15, ensuring the accuracy and stability of the movement of the movable plate 17. These positional relationships cooperate with each other, so that the movable plate 17 can move smoothly and accurately in a specific direction, thereby realizing related functions, such as driving the insertion rod 14 to perform fixing operations.

[0031] In the embodiment of the present invention, the left side of the movable plate 17 is fixedly connected to the telescopic end of the electric push rod 10, and the other end of the electric push rod 10 is fixedly connected to the placement block 9. The electric push rod 10 can provide power for the movement of the movable plate 17. When the electric push rod 10 is extended or retracted, its telescopic end drives the movable plate 17 to move left and right along the inner groove 15. A plug rod 14 is provided below the electric push rod 10. The plug rod 14 is inserted and connected to the inside of the socket 7. The plug rod 14 cooperates with the socket 7 to fix the position of the placement block 9. When the insertion rod 14 is inserted into the socket 7, it can prevent the placement block 9 from moving in the placement groove 6, achieving stable positioning. The insertion rod 14 passes through the left side of the placement block 9 and is fixedly connected to the movable plate 17, and the insertion rod 14 is slidingly connected to the left side of the placement block 9. This connection method ensures that the movement of the movable plate 17 can drive the insertion rod 14 to move synchronously. At the same time, the insertion rod 14 can slide relative to the placement block 9, thereby realizing the action of inserting or removing the socket 7. These positional relationships enable the electric push rod 10 to control and fix the position of the placement block 9 through the movable plate 17 and the insertion rod 14, thereby achieving the purpose of layering and fixing the cables.

[0032] Working principle: First, start the electric push rod 10, the electric push rod 10 extends and pushes the movable plate 17 to move right, and the movable plate 17 drives the plug 14 to move right until the plug 14 completely enters the placement block 9, and then the placement block 9 is clamped in the placement slot 6, and the electric push rod 10 is started again, the electric push rod 10 contracts and drives the movable plate 17 to move left so that the plug 14 is inserted into the socket 7, so that the placement block 9 and the arc block 8 can be fixed in position, and finally the cables are passed through the two arc blocks 8 respectively. This design can effectively organize the cables in layers, avoid the cables from being entangled and confused, increase the air circulation space between the cables, reduce the situation where the working temperature of the cables increases due to the difficulty in dissipating heat, and accelerates the aging of the insulation layer, thereby improving the cable In order to extend the service life, several placement slots 6 are provided inside the cable tray, and multiple layered components can be arranged in different positions according to needs. Then the plug plates 12 at both ends of the lower part of the cable tray upper plate 2 are inserted into the slots 13 opened on the upper end surface of the lower plate 1 of the cable tray. Then, holding the handle 5, the card block 4 is aligned with the front end of the card slots 3 opened at both ends of the cable tray upper plate 2 and the cable tray lower plate 1, and the card block 4 is slid into the card slot 3 to fix the cable tray upper plate 2 and the cable tray lower plate 1, thereby realizing the installation of the cable tray. When disassembling, only the card block 4 needs to be slid out of the card slot 3 to disassemble the cable tray. There is no need to rely on the elasticity of the spring to prevent the spring from weakening due to long-term use and affecting the normal disassembly of the cable tray.
