Description

Technical Field

[0001] This utility model belongs to the field of cable tray conversion devices, and particularly relates to a multi-layer stranded cable tray conversion box. Background Technology

[0002] Cable trays, as a key non-structural component, provide support for the laying of cables, voice and communication equipment. They are an indispensable part of the overall cabling project and can also be called the "lifeline" of a building, playing an important role in modern architecture.

[0003] In many construction projects, substandard or unreasonable design and construction processes have led to poor construction quality and even serious quality problems. This not only affects the normal use of the project but also poses significant hidden dangers and can even cause serious economic losses. Therefore, it is essential to strictly adhere to the specifications and requirements throughout the entire construction process.

[0004] Therefore, cables in cable trays must be arranged neatly, without any crossing or overlapping. After laying, the cables should be horizontal and vertical. At the same time, the cable routing should be considered during laying to ensure that each section is the same length and to avoid crossing. This ensures the correctness and stability of the cable tray installation position. In addition, each cable tray should be clearly marked at both ends.

[0005] Traditional cable trays typically employ multi-channel single-layer structures or upward-folding bridges at intersections. This inevitably leads to a messy and disorganized arrangement of cables at the cable tray conversion boxes. Alternatively, using upward-folding bridges to avoid collisions results in material waste, increased support points, and excessive space occupation, making them highly susceptible to limitations during use.

[0006] For example, an existing patent, "A Layered Multi-Pass Cable Tray Assembly Device" (CN202221847477.X), belongs to the field of building technology. It includes a connecting structure comprising a first side, a second side, a third side, and a fourth side. The first and second sides are opposite to each other, as are the third and fourth sides. Multiple first connecting slots are provided on the first side, with multiple first partitions extending along the length of these slots to form a first channel for cable laying through adjacent partitions. Multiple second connecting slots are provided on the second side, with multiple second partitions extending along the length of these slots. Multiple third connecting slots are provided on the third side, with multiple third partitions extending along the length of these slots. This layered multi-pass cable tray assembly device has a fixed number of connecting slots, making it unable to be quickly and adaptably modified according to different usage scenarios, resulting in limited practical applications and inconvenience in use.

[0027] Example 1 refer to Figures 1 to 3 As shown in the figure, a multi-layer stranded cable tray conversion box is presented. This device is a simple and portable multi-layer stranded cable tray conversion box tool. It adopts integrated cabling to combine several previously independent and incompatible cabling types into a complete cabling system, effectively saving material waste and three-dimensional space. Furthermore, some measures are adopted to make the cable tray conversion box more conducive to cable pulling and to pay more attention to fire resistance and waterproofing.

[0028] The multi-layer cable tray conversion box in this embodiment includes: a first conversion area 102 and a three-way cable tray structure, wherein the first conversion area 102 is located at the intersection of the three-way cable tray structure.

[0029] Preferably, the three-way cable groove structure described in this embodiment corresponds to three first cable grooves 104, which form a T-shaped structure distribution, and the intersection area of ​​the three first cable grooves 104 is the first transition area 102.

[0030] Preferably, the first cable tray 104 is provided with a plurality of first stranding plates 106 to complete the horizontal space division within the first cable tray 104 so as to meet the requirements of various types of cables passing through in strands.

[0031] Preferably, the first transfer area 102 is provided with a first layering plate 109, which is used to complete the vertical spatial division of the corresponding area so as to meet the layered passage of various cables.

[0032] Preferably, in this embodiment, the multi-layer cable tray conversion box is formed by interlocking the first bottom plate 101 and the first top plate 111 to form a box structure.

[0033] Preferably, the first base plate 101 has a plurality of first branch slots 105 on the main body corresponding to the first wire groove 104, which are parallel to the direction of the wire groove structure, and each first branch plate 106 is inserted into the first branch slot 105.

[0034] Specifically, the first branch slot 105 can be effectively set according to the actual number of cable strands on site. For example, setting one first branch slot 105 will divide the cable into two cable channels on the same layer; two first branch slots 105 will divide the cable into three cable channels on the same layer; and three first branch slots will divide the cable into four cable channels on the same layer.

[0035] The first stranding plate 106 is inserted into the first stranding slot 105 for splicing cables along their length, effectively "diverting" the cables. It can be used to place different professional cables or cables with different functions, "diverting" multiple cables that seem disorganized, making the cables clear and avoiding the chaos caused by too many cables.

[0036] Preferably, the first transition area 102 on the first base plate 101 is provided with a plurality of first drainage holes 103 on the corresponding main body. The corresponding first drainage holes 103 not only realize the outward discharge of water that may be generated inside the box, but also realize the ventilation and gas interaction between the inner and outer spaces of the box, thereby helping to achieve heat dissipation of the box.

[0037] Preferably, the first base plate 101 has a layered slot on the edge sidewall of the first transition area 102, and the first layered plate 109 is snapped into the layered slot to achieve vertical space division in the corresponding area. This allows for the placement of cables of different specialties or functions, effectively "enclosing" the previously complex cables within a cable box, saving space, reducing material waste, and making the upper and lower layers or multiple layers of cables clearer and more organized, effectively avoiding the mess and disorder caused by excessive cables.

[0038] Furthermore, the first layer plate 109 is provided with a hollow structure, which allows air to circulate between the upper and lower layers, thus playing a role in heat dissipation. At the same time, it also prevents "steam water" generated due to temperature difference from accumulating here, allowing it to flow to the bottom of the cable tray box, which also plays a role in local waterproofing.

[0039] Preferably, the first top plate 111 has a plurality of first waterproof louvers 112 at the position of the first transition area 102 corresponding to the main body. The first waterproof louvers 112 in the central area of ​​the first top plate 111 not only allow the cable tray conversion box to communicate with the outer frame, thus avoiding the risk of fire due to excessive temperature in the area caused by too many cables in the conversion box, but also seal the entire cable tray, playing a role in dust prevention and waterproofing. In addition, it can also prevent the exposed cables from being damaged by mosquitoes, rats, etc., thus effectively protecting them.

[0040] Preferably, the first base plate 101 and the first top plate 111 are respectively provided with a first through hole 107 and a third through hole 113 on the side wall of the corresponding wire trough structure.

The first base plate 101 and the first top plate 111 can be fixed by passing the first fixing bolt 110 through the corresponding through hole structure.

[0041] Furthermore, the first branch plate 106 is also provided with a hole structure, namely a second through hole 108. When the first fixing bolt 110 passes through the through hole on the side wall of the corresponding cable tray structure of the first bottom plate 101 and the first top plate 111, it simultaneously passes through the second through hole 108 on the first branch plate 106, thereby strengthening the structure of the first branch plate 106, preventing the first branch plate 106 from deforming due to cable compression, and ensuring the overall stability of the cable tray box.

[0042] Preferably, the multi-layer cable tray conversion box is also equipped with a temperature and smoke alarm inside the box, which is used to determine the temperature and smoke inside the cable tray conversion box and to play an alarm role. When the temperature inside the cable tray conversion box reaches a certain level or a large amount of smoke appears, an alarm will be triggered immediately to draw attention.

[0048] Preferably, in this embodiment, the multi-layer cable tray conversion box is formed by the interlocking of the second bottom plate 201 and the second top plate 210 to form a box structure.

[0050] Specifically, the second branch slot can be effectively set according to the actual number of cable strands on site. For example, setting one second branch slot will divide the cable into two cable channels on the same layer; two second branch slots will divide the cable into three cable channels on the same layer; and three second branch slots will divide the cable into four cable channels on the same layer.

[0051] The second branching plate 205 is inserted into the second branching slot for splicing cables along their length, effectively "diverting" the cables. It can be used to place different professional cables or cables with different functions, "diverting" multiple cables that seem disorganized, making them clear and avoiding the chaos caused by too many cables.

[0052] Preferably, the second transition area 202 on the second base plate 201 is provided with a plurality of second drainage holes 203 corresponding to the main body.

[0054] Furthermore, the second layer plate 208 is provided with a hollow structure, which allows air to circulate between the upper and lower layers, thus playing a role in heat dissipation.
