[0024] Ginseng Figure 1-3 As shown, an embodiment of the utility model is a large-span high-strength cable tray, including a cable tray body 1, a placement plate 2 is arranged at the upper end inside the cable tray body 1, and reinforcement components are arranged at the upper end and the lower end of the placement plate 2.

[0025] The reinforcement component includes a telescopic rod 3, a spring 4, a bottom plate 5, and a reinforcing rib 6. A plurality of telescopic rods 3 are fixedly arranged on the lower end surface of the placement plate 2. The other end of the telescopic rod 3 is fixedly arranged on the bottom plate 5. The lower end surface of the bottom plate 5 is fixedly arranged at the bottom inside the cable tray body 1. A spring 4 is sleeved on the outer side of the telescopic rod 3. One end of the spring 4 is fixedly arranged on the lower end surface of the placement plate 2, and the other end of the spring 4 is fixedly arranged at the bottom inside the cable tray body 1.

[0026] When the cable is placed on the placement plate 2, the stress of the cable concentrated in the middle part of the placement plate 2 can be transmitted to the bottom plate 5 through the spring 14, and then evenly transmitted to the cable tray body 1 through the bottom plate 5, thereby avoiding stress concentration and ensuring the structural strength of the cable tray body 1.

[0027] A reinforcing rib 6 is fixedly arranged between the left and right sides of the cable tray body 1, and five reinforcing ribs 6 are arranged. The arrangement of the reinforcing rib 6 can play a role in strengthening the structural strength of the cable tray body 1, thereby effectively preventing the cable tray body 1 from bending due to stress.

[0028] The upper end surfaces of the left and right ends of the cable tray body 1 are fixed with mounting plates 7, and the upper end surfaces of the mounting plates 7 are provided with multiple screw holes 8, which can be used to fix the mounting plates 7 to the designated mounting positions, thereby completing the installation of the cable tray body 1.

[0029] The left and right sides of the upper end surface of the placement plate 2 are provided with mounting grooves 9, and the interior of the mounting grooves 9 and the upper end of the placement plate 2 are provided with clamping components. The opening of the mounting grooves 9 facilitates the installation of subsequent components.

[0030] like Figure 1 , Figure 3 , Figure 4 As shown, the clamping assembly includes a moving block 10, a limiting groove 11, a limiting rod 12, a spring 13, a clamping plate 14, and a rubber pad 15. The moving block 10 is arranged inside the mounting groove 9, and two limiting grooves 11 are opened on the right side of the moving block 10. The limiting rod 12 is arranged inside the limiting groove 11. The two ends of the limiting rod 12 are fixedly arranged on the left and right sides of the mounting groove 9. The outer side of the limiting rod 12 is sleeved with a spring 13, one end of the spring 13 is fixedly arranged on the outer side of the moving block 10, and the other end of the spring 13 is fixedly arranged on the outer side of the mounting groove 9. When the moving block 10 moves outward, the spring 13 is compressed, and the rebound force of the spring 13 can play a clamping role.

[0031] Specifically, a clamping plate 14 is fixedly provided on the upper end surface of the moving block 10, and a rubber pad 15 is fixedly provided on the inner side of the clamping plate 14. The clamping plates 14 on both sides are pushed outward, and the moving block 10 also moves outward, and the second spring 13 is compressed. After the cable bundle is placed on the placement plate 2, the clamping plate 14 is released, and the rebound force of the second spring 13 can push the moving block 10, the clamping plate 14, and the rubber pad 15 to move inward, so that the clamping plate 14 and the rubber pad 15 can play a role in clamping and fixing the cable bundle.

[0032] When the embodiment of the utility model is used, the mounting plate 7 is first aligned with the specified mounting position, and then the cable tray body 1 can be installed by using bolts through the screw holes 8, and the clamping plates 14 on both sides are pushed outward. At this time, the moving block 10 also moves outward, and the spring 13 is compressed. After the cable bundle is placed on the placement plate 2, the clamping plate 14 is released, and the rebound force of the spring 13 can push the moving block 10, the clamping plate 14, and the rubber pad 15 to move inward, so that the clamping plate 14 and the rubber pad 15 can play a role of clamping and fixing the cable bundle to prevent it from sliding; wherein the reinforcement component is set, when the cable bundle is placed on the placement plate 2, the stress of the cable bundle concentrated in the middle part of the placement plate 2 can be transmitted to the bottom plate 5 through the spring 14, and evenly transmitted to the cable tray body 1 through the bottom plate 5, which can avoid stress concentration. At the same time, the reinforcing ribs 6 can also play a role of strengthening the structural strength of the cable tray body 1, effectively avoiding the bending of the cable tray body 1 and improving its safety.

[0033] The above shows and describes the basic principles of the present invention. The above are only preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only intended to illustrate the principles of the present invention. Without departing from the scope of the present invention, any modifications, equivalent substitutions and improvements made within the spirit and scope of the present invention should be included in the protection scope of the present invention.
