Description

Technical Field

[0001] The utility model relates to a high-strength shock-absorbing cable tray. Background Art

[0002] In the modern industrial and construction fields, a cable tray is a support system for installing cables. It not only needs to bear the weight of the cables but also protect the cables from the influence of the external environment. During the use of the cable tray, various challenges will be faced, such as mechanical vibrations, seismic fluctuations, or other external forces. These factors will have a negative impact on the stability of the tray and the performance of the cables.

[0003] Traditional cable trays usually adopt a rigid structure design and lack effective shock-absorbing mechanisms. When encountering vibrations or impacts, this structure cannot effectively absorb and relieve the action of forces, easily leading to damage to the tray structure or loosening of the cable interfaces, affecting the stable operation of the entire power or communication system.

[0022] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below with reference to the embodiments and the drawings, but the implementation manners of the present utility model are not limited thereto.

[0023] As Figures 1 - 4 shown, the high-strength shock-absorbing cable tray provided in this embodiment includes an upper bottom plate 1, a lower bottom plate 2, and two side plates 3 whose bottoms are inserted between the upper bottom plate 1 and the lower bottom plate 2. A plurality of springs 4 are arranged between the upper bottom plate 1 and the lower bottom plate 2, and a rubber pad 5 is arranged between the upper bottom plate 1 and the lower bottom plate 2. Through holes 6 for the springs 4 to pass through are arranged on the rubber pad 5. The double-layer bottom plate design of the upper bottom plate 1 and the lower bottom plate 2 is adopted, which improves the strength of the cable tray. A plurality of springs 4 are arranged in the middle, enhancing the overall shock absorption performance, and a rubber pad 5 is arranged therein to further improve the shock absorption effect.

[0024] In this embodiment, as Figure 1 shown, the upper bottom plate 1 is a U-shaped structure with an opening downward, and the side plate 3 is an L-shaped structure. A groove 7 is provided on the bottom edge of the side plate 3, and both ends of the upper bottom plate 1 are inserted into the groove 7, so that the cable tray has high rigidity and stability, and can effectively disperse and transfer external forces.

[0025] In this embodiment, as Figure 4 shown, the free length value of the spring 4 is greater than the thickness value of the bottom edge of the side plate 3. During assembly, after the side plate 3 is inserted between the upper bottom plate 1 and the lower bottom plate 2, since the free length value of the spring 4 is greater than the thickness value of the bottom edge of the side plate 3, it is necessary to press down the upper bottom plate 1 so that both ends are inserted into the groove 7, and then use bolts to fix it. When pressing down the upper bottom plate 1, the spring 4 will be compressed, enabling the spring 4 to effectively convert and absorb energy, providing a good shock absorption effect.

[0026] In this embodiment, as Figure 4 shown, the thickness value of the rubber pad 5 is greater than the thickness value of the bottom edge of the side plate 3. The thickness value of the rubber pad 5 only needs to be slightly higher than the bottom edge of the side plate 3, so that when the upper bottom plate 1 is pressed down, the rubber pad 5 will be slightly compressed, ensuring that it can effectively play a role when subjected to vibration subsequently.

[0027] In this embodiment, as Figure 1 shown, reinforcing blocks 8 are provided on both sides of the lower bottom plate 2, and reinforcing ribs 9 are provided between the reinforcing blocks 8 and the side plate 3. There are three reinforcing blocks 8, and the three reinforcing blocks 8 are evenly distributed along the length direction of the lower bottom plate 2, enhancing the stability and load-bearing capacity of the cable tray.

[0028] In this embodiment, as Figure 1 shown, fixing plates 10 are provided on both sides of the reinforcing rib 9, and the reinforcing rib 9 is fixed to the side plate 3 by bolt connection.

[0029] In this embodiment, as Figure 1 shown, the spring 4 is provided in two columns, and each column of the spring 4 has four. The eight springs 4 are evenly distributed between the upper bottom plate 1 and the lower bottom plate 2, ensuring that the forces received by the springs 4 are evenly dispersed, avoiding deformation or damage caused by excessive local stress, and ensuring the shock absorption effect.

[0030] In summary, in this embodiment, the cable tray provided in this embodiment adopts a double-bottom design with an upper bottom plate 1 and a lower bottom plate 2, which improves the strength of the cable tray. A plurality of springs 4 are arranged in the middle to enhance the overall shock absorption performance, and a rubber pad 5 is arranged therein to further improve the shock absorption effect. The upper bottom plate 1 is a U-shaped plate with an opening downward and can be inserted into the groove 7 formed by the side plate 3, having high rigidity and stability, and can effectively disperse and transfer external forces. Reinforcing blocks 8 are arranged on both sides of the lower bottom plate 2, and reinforcing ribs 9 are arranged between the reinforcing blocks 8 and the side plate 3, which can effectively improve the overall load-bearing capacity and bending resistance of the cable tray.

[0031] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and concept of the present invention, makes equivalent substitutions or changes, all belong to the protection scope of the present invention.
