Description

Technical Field

[0001] The utility model relates to the technical field of cable trays, in particular to a ladder-type cable tray with an efficient heat dissipation function. Background Art

[0002] Cable trays are divided into structures such as trough type, tray type, ladder type and grid type, and are composed of components such as brackets and installation accessories. Cable trays in buildings can be erected independently or attached to various building and pipe gallery brackets. Among them, the main characteristics of the ladder-type tray are: light weight, convenient installation, good heat dissipation and air permeability, etc. Cable trays mainly play a supporting role for cables. In order to fix the position of the cables, in the prior art, the cables are usually directly tied into a bundle with cable ties and placed on the cable tray. However, the cables are prone to heat up during power-on, especially in relatively hot weather, the temperature on the surface of the cables will be higher. Even though the ladder-type cable has good heat dissipation performance, the heat energy between the cables accumulates. After long-term use, the surface of the cables is prone to aging, which may lead to safety accidents. This direct fixing method of tying the cables into a bundle with cable ties is not conducive to heat dissipation. Therefore, a new type of ladder-type cable tray is needed. Summary of the Invention

[0003] In order to solve the above problems, the utility model provides a ladder-type cable tray with an efficient heat dissipation function that can ensure the stable position of the cables and improve the heat dissipation performance of the cables. The technical solution of the utility model: A ladder-type cable tray with an efficient heat dissipation function includes a tray body and a plurality of partition components connected to the tray body. The partition components include two fixed bases connected to the tray body, a fixed cover plate slidably connected to the fixed bases, and a plurality of partition plates connected to the tray body. The partition plates are evenly distributed on the tray body. The fixed bases are provided with sliding grooves, and the fixed cover plates are provided with positioning protrusions. The shape and size of the positioning protrusions are adapted to those of the sliding grooves, and the positions of the positioning protrusions correspond to those of the fixed bases. When the positioning protrusions are completely inserted into the sliding grooves, the bottom of the fixed cover plate contacts the top of the partition plates.

[0004] With the above technical solution, when laying cables, the cables are arranged between two adjacent partition plates respectively. According to user requirements, during manufacturing, the distance between two adjacent partition plates can be set to the diameter of one cable or the diameter of two cables. In this way, the cables are separated by the partition plates, which can avoid the too small contact distance between the cables, resulting in overheating of the cable surface, thus greatly improving the heat dissipation efficiency of the cables. In addition, if there are too many cables to be arranged, the user can also set the partition plates into a multi-layer structure according to needs to meet the arrangement requirements of a large number of cables. After the cable arrangement is completed, align the positions of the positioning bumps with the sliding grooves and insert them, thus quickly fixing the positions of the cables. Further setting of the present utility model: the fixed base is provided with a first threaded hole, the positioning bump is provided with a second threaded hole, the fixed base and the positioning bump are connected by a fixing bolt, and the fixing bolt is respectively adapted to the shapes and sizes of the first threaded hole and the second threaded hole. When the positioning bump is completely inserted into the sliding groove, the positions of the first threaded hole and the second threaded hole correspond to each other, and the first threaded hole penetrates through the sliding groove.

[0005] With the above technical solution, after the cable position arrangement work is completed, insert the positioning bump into the sliding groove. At this time, the positions of the first threaded hole and the second threaded hole are aligned, and then install the fixing bolts into the first threaded hole and the second threaded hole respectively, so that the positions of the fixed base and the positioning bump are fixed, thereby ensuring the fixed position of the fixed cover plate, and further improving the fixing effect on the cable position.

[0006] Further setting of the present utility model: the surface of the partition plate is provided with a plurality of first ventilation holes evenly distributed on the partition plate, and the fixed cover plate is provided with a plurality of second ventilation holes evenly distributed on the fixed cover plate.

[0007] With the above technical solution, since the surface of the partition plate is provided with a plurality of first ventilation holes and the fixed cover plate is provided with a plurality of second ventilation holes, therefore, the contact area between the cables and the air can be further increased, thereby improving the heat dissipation effect on the cables.

[0008] Further setting of the present utility model: the fixed cover plate is provided with a fixed groove, and a dust-proof net is provided on the fixed groove. The dust-proof net is adapted to the shape and size of the fixed groove. With the above technical solution, since the dust-proof net is provided on the fixed groove, the dust-proof net can not only play a dust-proof role, but also further increase the contact area between the cables and the air, thereby improving the heat dissipation effect on the cables. In addition, this can also reduce the weight of the fixed cover plate, reduce the manufacturing cost, and lower the installation difficulty. Description of the Drawings

Specific implementation manner

[0014] As Figures 1-4 shown, a stepped cable tray with high - efficiency heat dissipation function includes a cable tray body 1 and a number of partition components 2 connected to the cable tray body 1. The partition component 2 includes two fixed bases 3 connected to the cable tray body 1, a fixed cover plate 4 slidably connected to the fixed bases 3, and a number of partition boards 5 connected to the cable tray body 1. The partition boards 5 are evenly distributed on the cable tray body 1. The fixed base 3 is provided with a sliding groove 6, and the fixed cover plate 4 is provided with a positioning convex block 7. The shape and size of the positioning convex block 7 are adapted to those of the sliding groove 6, and the position of the positioning convex block 7 corresponds to that of the fixed base 3. When the positioning convex block 7 is completely inserted into the sliding groove 6, the bottom of the fixed cover plate 4 contacts the top of the partition board 5. When laying cables, the cables are respectively arranged between two adjacent partition boards 5. According to user requirements, during production, the distance between two adjacent partition boards 5 can be set to the diameter size of one cable or the diameter size of two cables. In this way, the cables are separated by the partition boards 5, which can prevent the contact distance between the cables from being too small, resulting in overheating of the cable surface, thus greatly improving the heat dissipation efficiency of the cables. In addition, if there are too many cables to be arranged, the user can also set the partition boards 5 into a multi - layer structure as needed to meet the arrangement requirements for a large number of cables. After the cable arrangement is completed, the positions of the positioning convex blocks 7 are respectively aligned with the positions of the sliding grooves 6 and inserted, thus completing the rapid fixation of the cable positions.

[0015] The fixed base 3 is provided with a first threaded hole 8, and the positioning convex block 7 is provided with a second threaded hole 9. The fixed base 3 and the positioning convex block 7 are connected by a fixing bolt 10. The fixing bolt 10 is respectively adapted to the shapes and sizes of the first threaded hole 8 and the second threaded hole 9. When the positioning convex block 7 is completely inserted into the sliding groove 6, the positions of the first threaded hole 8 and the second threaded hole 9 correspond to each other, and the first threaded hole 8 penetrates through the sliding groove 6.

[0016] After the cable position arrangement work is completed, the positioning convex block 7 is inserted into the sliding groove 6. At this time, the positions of the first threaded hole 8 and the second threaded hole 9 are aligned. Then, the fixing bolts 10 are respectively installed into the first threaded hole 8 and the second threaded hole 9, so that the positions of the fixed base 3 and the positioning convex block 7 are fixed, thereby ensuring the fixed position of the fixed cover plate 4, and further improving the fixing effect on the cable position.

[0017] The surface of the partition plate 5 is provided with a plurality of first ventilation holes 11 evenly distributed on the partition plate 5, and the fixed cover plate 4 is provided with a plurality of second ventilation holes 12 evenly distributed on the fixed cover plate 4.

[0018] Since the surface of the partition plate 5 is provided with a plurality of first ventilation holes 11 and the fixed cover plate 4 is provided with a plurality of second ventilation holes 12, the contact area between the cable and the air can be further increased, thereby improving the heat dissipation effect on the cable.

[0019] The fixed cover plate 4 is provided with a fixed groove 13, and a dust-proof net 14 is arranged on the fixed groove 13. The dust-proof net 14 is adapted to the shape and size of the fixed groove 13.

[0020] Since the fixed groove 13 is provided with a dust-proof net 14, the dust-proof net 14 can not only play a dust-proof role, but also further increase the contact area between the cable and the air, thereby improving the heat dissipation effect on the cable. In addition, this can also reduce the weight of the fixed cover plate 4, reduce the manufacturing cost, and lower the installation difficulty.
