Description

Technical Field

[0001] This application relates to the field of cable support technology, and more specifically, to a cable support suitable for cable trenches. Background Technology

[0002] Cable supports are typically installed on the side walls of structures such as cable trenches and tunnels. When laying cables, these supports are erected to provide support or even fix the cables in place, thus enabling cable positioning. However, current cable supports generally consist of a base and an arm. The base is connected to the side wall of the cable trench or tunnel, while the arm extends along the width of the structure. The cables are supported and fixed to the arm. However, when using current cable supports, the cable capacity of cable trenches and tunnels is limited.

[0003] In conclusion, how to increase the cable capacity of cable trenches is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a cable support suitable for cable trenches, which can effectively increase the cable capacity of the cable trench.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A cable support suitable for cable trenches includes: a top plate and support legs;

[0007] The first end of the support leg is used to abut against the bottom of the cable trench, and the second end of the support leg is fixedly connected to the top plate so that the top plate is buried at the middle of the depth of the cable trench.

[0008] The support leg is connected to the middle position of the top plate along its own length direction, and the top plate along its own length direction and the structures on both sides of the support leg respectively form two independent accommodating spaces with the support leg, the accommodating spaces being used for inserting cables.

[0009] Preferably, the number of the support legs is greater than or equal to two, and the support legs are arranged sequentially and at intervals along the length of the top plate.

[0010] Preferably, the top plate has cable fixing holes for inserting cable retainers to fix cables inserted in the accommodating space.

[0011] Preferably, the cable support suitable for cable trenches further includes a reinforcing rib, the first end of which is connected to the top plate, the second end of which is connected to the support leg, and the reinforcing rib is arranged in a triangular shape with the support leg.

[0012] Preferably, the first end of the support leg has a foot for abutting against the bottom of the cable trench.

[0013] Preferably, the cable support for cable trenches, having the top plate, two supporting legs and the bottom foot, is a Π-shaped structure, and the number of reinforcing ribs is two, with the two reinforcing ribs symmetrically arranged on opposite sides of the two supporting legs.

[0014] Preferably, the intersections between the support leg and the top plate, the intersections between the reinforcing rib and the top plate, and the intersections between the reinforcing rib and the support leg all have rounded corner structures, and the radius of the rounded corner structure is greater than 5mm.

[0015] Preferably, the cable support suitable for cable trenches is a molded integral structural component.

[0016] Preferably, the cable support suitable for cable trenches is a sheet molding compound.

[0017] Preferably, the top plate has bracket fixing holes for connecting a grounding device to fix the cable bracket of the cable trench in the cable trench.

[0018] In this application, the second end of the support leg is connected to the top plate, and the upper end of the support leg is connected to the middle position of the top plate along its own length. The structure of the top plate on the first side of the support leg and the structure on the second side of the support leg both form an accommodating space with the support leg. In other words, the space on the same side of the top plate is divided into at least two independent accommodating spaces by the support leg. The cable bracket can be buried in the bottom space of the cable trench, that is, the height of the cable bracket is less than the depth of the cable trench. When the cable bracket suitable for cable trenches is placed in the cable trench for use, the support leg extends along the depth direction of the cable trench, and the top plate is located at the middle position of the depth of the cable trench. The cross section of the cable trench where the cable bracket is set is divided into several areas. Among them, the top plate and the part of the trench sidewall near the trench opening form an area, as well as the above-mentioned at least two accommodating spaces. According to related technologies, the cable bracket can reasonably divide the cable trench. For example, it can fix cables of different specifications such as high voltage and low voltage separately, which is beneficial to increase the cable capacity of the cable trench while ensuring electrical safety.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] The core of this application is to provide a cable support suitable for cable trenches, which can effectively increase the cable capacity of cable trenches.

[0029] This application provides a cable support suitable for cable trenches, including a top plate 1 and support legs 2;

[0030] The first end of the support leg 2 is used to abut against the bottom of the cable trench, and the second end of the support leg 2 is fixedly connected to the top plate 1 so that the top plate 1 is buried in the middle of the depth of the cable trench.

[0031] The support leg 2 is connected to the middle position of the top plate 1 along its own length direction, and the top plate 1 along its own length direction and the structures on both sides of the support leg 2 respectively form two independent accommodating spaces, which are used for inserting cables.

[0032] refer to Figure 1 and Figure 2 As explained, the support leg 2 extends vertically, with its upper end connected to the top plate 1. The upper end of the support leg 2 is also connected to the middle of the top plate 1 in the horizontal direction. Therefore, the structures on the top plate 1 to the left and right of the support leg 2 form an accommodating space with it. In other words, the bottom space of the top plate 1 is divided by the support leg 2 into at least two independent accommodating spaces. Furthermore, the cable support can be buried in the bottom space of the cable trench, meaning the height of the cable support is less than the depth of the cable trench. Thus, the cable support suitable for cable trenches can be placed... When used in cable trenches, the support leg 2 extends along the depth of the cable trench, and the top plate 1 is located in the middle of the depth of the cable trench. The cross-section of the cable trench with this cable support is divided into several areas. Among them, the top plate 1 and the part of the trench sidewall near the trench opening form an area, as well as the above-mentioned at least two accommodating spaces. According to related technologies, the cable support can reasonably divide the cable trench. For example, it can fix cables of different specifications such as high voltage and low voltage in separate areas, which is beneficial to increase the cable capacity of the cable trench while ensuring electrical safety.

[0033] Based on the above embodiment, the number of support legs 2 is greater than or equal to two, and several support legs 2 are arranged sequentially and at intervals along the length direction of the top plate 1.

[0034] refer to Figure 1 and Figure 2 As can be seen, several support legs 2 are connected to the top plate 1 and are located below the top plate 1. The several support legs 2 and the top plate 1 cooperate to form at least three accommodating spaces.

[0035] In some specific embodiments, when the number of support legs 2 is two, such as... Figure 1 and Figure 2 As shown, the left support leg 2 is defined as the first support leg 2, and the right support leg 2 is defined as the second support leg 2. The first support leg 2 and the part of the top plate 1 located to the left of the first support leg 2 form an accommodating space. The second support leg 2 and the part of the top plate 1 located to the right of the second support leg 2 form another accommodating space. The first support leg 2, the second support leg 2 and the part of the top plate 1 located to the right of the first support leg 2 and to the left of the second support leg 2 form yet another accommodating space. In this embodiment, the cable bracket has three independent accommodating spaces.

[0036] In some specific embodiments, when the number of support legs 2 is three, such as... Figure 5 The leftmost support leg 2 is defined as the third support leg 2, the rightmost support leg 2 as the fourth support leg 2, and the middle support leg 2 as the fifth support leg 2. The third support leg 2 and the portion of the top plate 1 located to the left of the third support leg 2 form an accommodating space; the fourth support leg 2 and the portion of the top plate 1 located to the right of the fourth support leg 2 form another accommodating space; the third support leg 2, the fifth support leg 2 and the portion of the top plate 1 located to the right of the third support leg 2 and to the left of the fifth support leg 2 form yet another accommodating space; the fourth support leg 2, the fifth support leg 2 and the portion of the top plate 1 located to the left of the fourth support leg 2 and to the right of the fifth support leg 2 form the remaining accommodating space. In this embodiment, the cable bracket has four independent accommodating spaces.

[0037] It should be noted that when the number of support legs 2 is greater than four, the same principle applies to the above embodiment where the number of support legs 2 is three.

[0038] Of course, the number of support legs 2 in this application is not limited to two or more. When only one support leg 2 is set, the structure formed by the fixed connection between the top plate 1 and the support leg 2 is T-shaped.

[0039] Based on the above embodiment, the top plate 1 has a cable fixing hole 11 for inserting a cable fixing device to fix the cable inserted in the accommodating space.

[0040] refer to Figure 1 and Figure 3 As explained, the cable fixing hole 11 extends vertically through the top plate 1. In use, the end of the cable clamp or cable tie or other cable fixing device is inserted into the cable fixing hole 11 so that the cable can be fixed on the cable bracket by the cable fixing device.

[0041] Preferably, cable fixing holes 11 are provided in corresponding parts of the top plate 1 that encloses and forms several accommodating spaces.

[0042] Based on the above embodiments, the cable support suitable for cable trenches also includes a reinforcing rib 3, with the first end of the reinforcing rib 3 connected to the top plate 1 and the second end connected to the support leg 2, and arranged in a triangular shape with the support leg 2.

[0043] refer to Figure 1 and Figure 2 As explained, the top plate 1 and the support leg 2 are reinforcedly connected by a reinforcing rib 3. The support leg 2 is perpendicular to the top plate 1. The reinforcing rib 3 is inclined relative to both the support leg 2 and the top plate 1, and intersects with them for fixed connection. In other words, the transition position between the top plate 1 and the support leg 2 is formed into a triangular reinforcement structure by the reinforcing rib 3, which effectively improves the load-bearing capacity of the cable bracket.

[0044] It should be noted that the number of reinforcing ribs 3 connected to the same support leg 2 can be one or two.

[0045] Based on the above embodiment, the first end of the support leg 2 has a foot 4, which is used to abut against the bottom of the cable trench.

[0046] refer to Figure 1 and Figure 2 As explained, a foot 4 is provided on the top of the support member. After the cable bracket is placed in the cable trench, the support leg 2 is supported on the bottom wall of the cable trench by the foot 4, which can improve the positioning accuracy and stability of the cable bracket in the cable trench.

[0047] Based on the above embodiment, the cable support suitable for cable trenches, which has a top plate 1, two supporting legs 2 as shown, and a bottom foot 4, has a Π-shaped structure. The number of reinforcing ribs 3 is two, and the two reinforcing ribs 3 are symmetrically arranged on the two supporting legs 2 on opposite sides.

[0048] Please refer to Figure 1 and Figure 2 In this embodiment, two support legs 2 are connected to the bottom of the top plate 1, and a foot 4 is provided at the bottom end of each support leg 2. Thus, the top plate 1, the two support legs 2 and the two foot 4 are fixedly connected to form an integral structure of Π shape. Correspondingly, two reinforcing ribs 3 are provided. One reinforcing rib 3 is located on the left side of the left support leg 2, and the other reinforcing rib 3 is located on the right side of the right support leg 2. The cable bracket has a simple structure and high stability.

[0049] Please refer to Figure 1 and Figure 4 Based on the above embodiment, the intersection of the support leg 2 and the top plate 1, the intersection of the reinforcing rib 3 and the top plate 1, and the intersection of the reinforcing rib 3 and the support leg 2 all have rounded corner structures 5, and the radius of the rounded corner structure 5 is greater than 5mm. This setting is beneficial for molding and also helps to improve strength and lifespan.

[0050] Based on the above embodiments, the cable support suitable for cable trenches is a molded integral structure, which results in higher production efficiency and higher quality stability. Preferably, the cable support suitable for cable trenches is a molded integral structure with a curing temperature range of 140-150℃ and a curing time range of 2-3 minutes, which results in higher quality.

[0051] Based on the above embodiments, the cable support suitable for cable trenches is a sheet molding compound part. Compared with related technologies, the cable support is lighter, usually reducing weight by more than 50%, and has lower production costs, operating costs, maintenance costs and usage costs. It also has higher corrosion resistance and a longer service life.

[0052] Based on the above embodiment, the top plate 1 has a bracket fixing hole 12, which is used to connect a grounding device to fix the cable bracket of the cable trench in the cable trench.

[0053] refer to Figure 1 and Figure 3 As explained, the bracket fixing hole 12 extends vertically through the top plate 1, and the grounding device can be fixedly connected by means of the bracket fixing hole 12. For example, the bottom end of the grounding device is inserted into the bracket fixing hole 12 and threadedly connected to the bracket fixing hole 12, or a screw is inserted into the bracket fixing hole 12 from bottom to top, and then inserted into the threaded hole at the bottom end of the grounding device, etc.

[0054] It should be noted that there are no restrictions on the specific type of grounding device, as long as it can meet the grounding requirements. For example, expansion bolts can be used, or L-shaped or straight strip plates can also be used.
