Description

Technical Field

[0001] This utility model relates to the field of power equipment installation technology, and in particular to a vertically grounded frame-type cable shaft. Background Technology

[0002] With the continuous improvement of power grid construction, the number of conventional substations is constantly increasing, and the issue of fire prevention in substations is receiving increasing attention. To improve fire resistance, many substations are beginning to use autoclaved aerated concrete (AAC) blocks (commonly known as aerated bricks) for constructing non-load-bearing walls. This material is lightweight and has excellent fire-resistant properties. However, inside substations, there are numerous cable laying channels, and vertically laid cable trays, cable racks, or cable supports are typically required between different floors. The traditional installation method involves using expansion bolts to fix these devices to the building walls before laying the cables. However, when AAC blocks are used on the walls, their low surface strength means that the installation of expansion bolts can cause the AAC blocks to crack, making it impossible to install and use cable trays, cable racks, or supports in the conventional way. This presents a serious technical challenge to cable laying in substations, especially in vertical laying scenarios, where a solution that can independently support cables without relying on wall strength is lacking. Utility Model Content

[0004] The technical solution adopted by this utility model to solve its technical problem is: A vertically grounded frame-type cable shaft includes: The vertical frame includes an upper frame and a lower frame, and a number of supporting vertical rods connected between the upper frame and the lower frame. The upper frame, the lower frame, and the supporting vertical rods together form a cuboid frame. The upper frame and / or the lower frame are also provided with a number of auxiliary fixing connection holes on their sides. Several fixed frames are arranged at intervals on the vertical frame. Each fixed frame is a quadrilateral frame, and its four corners are respectively connected to the corresponding supporting vertical frame rod. Several cable brackets are connected to the fixed frame, wherein a cable laying section is formed between adjacent cable brackets or between the cable brackets and the fixed frame, and multiple cables are laid through the cable laying section accordingly. Several cable brackets are also provided on the upper frame and the lower frame respectively.

Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Detailed Implementation

[0012] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0013] Please see Figure 1 and Figure 2 As shown, this application provides a vertically grounded frame-type cable shaft, which is constructed by building an independent vertical frame 1 and arranging several fixed frames 2 at intervals on it, and then connecting several cable brackets 3 to the fixed frames 2. Thus, a cable laying section 4 is formed between adjacent cable brackets 3 or between cable brackets 3 and fixed frames 2. Multiple cables 100 are laid through the cable laying section 4, thereby effectively solving the problem that the cable laying device cannot be stably installed on low-strength walls.

[0014] Specifically, the vertical support 1, as the skeleton structure of the entire cable shaft, is mainly used to provide vertical support, bear the weight of the fixed frame 2, cable bracket 3 and cable 100, and ensure the stability of the entire shaft structure.

[0015] The fixing frame 2, which is set on the vertical frame 1, is used to provide connection points and support for the cable support arm 3, and its spaced arrangement helps to distribute the weight and installation pressure of the cable 100.

[0016] The cable support arm 3 is connected to the fixed frame 2. Its main function is to directly support and fix the cable 100 and guide the vertical direction of the cable 100.

[0017] The cable laying section 4 is a spatial area formed between adjacent cable brackets 3 or between cable brackets 3 and fixed frame 2, which is used to provide an orderly passage for multiple cables 100 and realize the standardized laying of cables 100.

[0018] Through the above technical solution, the vertically grounded frame-type cable shaft proposed in this application constructs a self-supporting structure independent of the building walls. Therefore, the cable laying device no longer relies on the wall's load-bearing capacity, effectively solving the problem of not being able to securely install the cable laying device with expansion bolts on aerated concrete block walls with low strength, ensuring that the cable 100 can be laid vertically safely and orderly.

[0019] Furthermore, the vertical frame 1 includes an upper frame 11 and a lower frame 12 respectively, and a plurality of supporting vertical rods 13 connected between the upper frame 11 and the lower frame 12, and a plurality of fixed frames 2 are respectively connected between the supporting vertical rods 13.

[0020] Specifically, the vertical frame 1 is subdivided into a combined structure of an upper frame 11, a lower frame 12, and supporting vertical rods 13. This application constructs a three-dimensional frame system with clearly defined boundaries and a supporting skeleton. The corresponding arrangement of the upper frame 11 and the lower frame 12 provides a stable reference at both ends of the entire shaft, while the supporting vertical rods 13 serve as connectors, linking the upper frame 11 and the lower frame 12 into a single load-bearing body with high structural strength. Based on this, fixed frames 2 are connected between the supporting vertical rods 13, using the supporting vertical rods 13 as the mounting base points for the fixed frames 2, allowing the fixed frames 2 to be evenly distributed and stably suspended inside the frame. This design transfers the weight of the cable 100 to the supporting vertical rods 13 through the fixed frames 2, and then distributes it to the upper frame 11 and the lower frame 12, thereby achieving the self-supporting function of the cable shaft and effectively avoiding excessive reliance on wall mounting points. Therefore, even in low-strength wall environments such as aerated concrete blocks, cable shafts can maintain structural stability, significantly improving the overall structure's resistance to compression and deformation. This solves the problems of wall damage and cable shaft swaying or insufficient structural strength when installing cable facilities on low-strength walls.

[0021] Furthermore, the upper frame 11, the lower frame 12, and the supporting vertical support rods 13 together form a cuboid frame.

[0022] Specifically, this application constructs a cuboid frame structure by spatially combining the upper frame 11, lower frame 12, and supporting vertical rods 13, thus providing a stable overall skeleton for the cable shaft. Through the geometric constraints of this cuboid frame, the vertical support 1 is no longer simply a stack of rods, but forms an independent support system with high torsional and bending resistance. This structural design allows the cable shaft to be installed vertically to the ground, directly transferring the weight of the cable 100 to the ground through the cuboid frame, thereby eliminating reliance on wall strength and effectively solving the problem of difficult cable bracket installation in low-strength installation environments such as aerated concrete block walls. The vertical alignment of the upper frame 11 and lower frame 12, and the longitudinal connection of the supporting vertical rods 13, ensures that the entire shaft maintains good verticality and structural rigidity when bearing the load of multiple cables 100, effectively avoiding overall deformation due to localized stress. This provides a stable benchmark for the subsequent installation of the fixing frame 2, ensuring the stability of the cable laying section 4 during long-term use.

[0023] Furthermore, the fixed frame 2 is a quadrilateral frame, with its four corners connected to the corresponding supporting vertical rods 13.

[0024] Specifically, the fixing frame 2 is designed as a quadrilateral structure, with its four corners connected to the four supporting vertical rods 13 of the cuboid frame, achieving stable positioning of the fixing frame 2 inside the shaft. This design distributes the stress points of the fixing frame 2 to the four supporting vertical rods 13, using the supporting vertical rods 13 as the main load-bearing skeleton, avoiding direct application of the weight of the cable 100 to the building wall, thus effectively solving the problem of installation with expansion bolts in aerated concrete block wall environments. The four-corner connection not only enhances the torsional resistance of the fixing frame 2 itself but also forms a rigid connection between the fixing frame 2 and the supporting vertical rods 13, ensuring the structural stability of the cable laying section 4 during long-term use and providing a reliable support foundation for the vertical laying of the cable 100. This structural design significantly improves the overall stability and load-bearing capacity of the entire frame-type cable shaft, making it particularly suitable for building environments where excessive loads on the walls must be avoided.

[0025] Furthermore, the upper frame 11 and the lower frame 12 are each provided with a number of cable support arms 3.

[0026] Specifically, in a vertically mounted frame-type cable shaft, the upper frame 11 and lower frame 12 serve as end support components of the entire structure. By additionally arranging cable brackets 3 at these locations, the laying range of the cable 100 can be effectively expanded, allowing the cable 100 to receive more stable support at its starting and ending points when entering or leaving the shaft. This design not only makes full use of the end space of the frame structure but also ensures the continuity and stability of the cable 100 throughout the entire height range of the shaft by directly integrating the cable brackets 3 onto the frame. This avoids problems such as cable sag or uneven stress caused by a lack of end support, thereby improving the reliability and space utilization efficiency of the overall cable laying system and enhancing the flexibility of the cable 100 layout.

[0027] Furthermore, the upper frame 11 and / or the lower frame 12 are provided with a number of auxiliary fixing connection holes.

[0028] Specifically, by providing several auxiliary fixing connection holes on the upper frame 11 and / or lower frame 12, this application offers an effective means to enhance the installation flexibility and structural stability of vertically installed frame-type cable shafts. In actual engineering installations, especially when facing low-strength building walls such as aerated concrete blocks, relying solely on the vertical frame 1's own structure for fixation may be insufficient to guarantee the long-term stability of the cable shaft. Through these auxiliary fixing connection holes, construction workers can use bolts, rivets, or other connectors to secondary connect or reinforce the upper frame 11 and / or lower frame 12 of the cable shaft to the building wall, embedded parts, or other auxiliary support structures. This design significantly improves the overall stability of the cable shaft during vertical installation, effectively avoiding structural loosening, displacement, or installation difficulties caused by insufficient wall strength or a single installation method. Simultaneously, these reserved connection holes provide standardized interfaces for subsequent maintenance, functional expansion, or integration with other equipment (such as fire protection systems, monitoring equipment, etc.) of the cable shaft, greatly improving installation efficiency and on-site adaptability, and ensuring the reliability and safety of cable laying.

[0029] Furthermore, the interval distance between adjacent fixed frames 2 is H, where the range of H is 1m ≤ H ≤ 2m.

[0030] Specifically, this application quantifies and limits the spacing between adjacent fixed frames 2 in a frame-type cable shaft, thereby achieving precise control over the overall structural rigidity and cable support strength of the cable shaft. By setting the spacing distance H within the range of 1 to 2 meters, sufficient support points can be ensured for the cable 100 during vertical laying, effectively preventing excessive deflection or displacement of the cable 100 within its span due to excessive self-weight, thus ensuring the safety of cable operation. Simultaneously, this range avoids material redundancy and limited installation space caused by excessively small support spacing, and also avoids insufficient structural strength caused by excessively large spacing. While meeting cable laying specifications, this optimizes the structural layout of the frame-type cable shaft, improving the overall installation reliability and construction efficiency. Given that the vertical frame 1 and fixed frames 2 together constitute a stable frame structure, this optimized spacing distance H further enhances the stability of the entire cable laying system, making the cable 100 less prone to deformation or damage during long-term operation, significantly improving the reliability and economy of cable laying.

[0031] In this embodiment, preferably, the value of H is 1.5m.

[0032] Furthermore, both the vertical frame 1 and the fixed frame 2 are constructed using No. 5 angle steel.

[0033] Specifically, No. 5 angle steel is a common type of steel with an L-shaped cross-section, typically 50 mm on each side. It possesses excellent bending and torsional resistance and structural rigidity. Its standardized production and ease of processing make it an ideal material for constructing load-bearing frame structures. Besides using No. 5 angle steel, in other embodiments, the vertical support 1 and the fixing frame 2 can also be made of other specifications of angle steel (e.g., No. 4 or No. 6.3 angle steel), or other steel materials with sufficient strength and rigidity, such as channel steel, square steel, or rectangular tubing, depending on actual load-bearing requirements and installation environment, to ensure the overall structural stability of the cable shaft. By uniformly using No. 5 angle steel for both the vertical support 1 and the fixing frame 2, not only is the structural material standardized and the processing and assembly process simplified, but the geometric characteristics of the angle steel also provide a stable mounting base for the subsequent connection of the cable support arm 3.

[0034] Furthermore, the cable support arm 3 is made of either No. 5 angle steel or No. 12 round steel.

[0035] Specifically, when the cable support arm 3 is made of No. 5 angle steel, this type of steel has an L-shaped cross-section, with two sides typically 50mm wide and 5mm or 6mm thick. Due to its unique cross-sectional geometry, No. 5 angle steel possesses a high section modulus of bending and good structural stability, effectively resisting vertical loads and lateral torsional forces. This allows the cable support arm 3, as a cable support component, to bear the weight of multiple cables 100 with its high strength and rigidity, without easily bending or deforming, thus providing robust and durable support for the cables 100. On the other hand, when the cable support arm 3 is made of No. 12 round steel, this steel refers to circular cross-section steel with a diameter of 12mm. Round steel has good tensile and compressive strength, and its surface is relatively smooth, making it easy to process and install. As the material for the cable support arm 3, No. 12 round steel can provide sufficient load-bearing capacity, ensuring that the cables 100 will not be damaged by deformation of the cable support arm 3 during long-term laying. Meanwhile, its circular cross-section may make it easier to place and adjust the cable 100 in certain applications, and help reduce local stress or wear on the cable 100 insulation layer.

[0036] In summary, in this embodiment of the application, multiple cables 100 are sequentially passed through these cable laying sections 4 during cable laying, and are supported by cable brackets 3. Since the entire frame-type cable shaft is vertically grounded and independently supported, the weight of the cables 100 is ultimately transferred to the ground through the cable brackets 3, the fixing frame 2, and the vertical frame 1, completely avoiding the direct load-bearing requirements on the autoclaved aerated concrete block wall.

[0037] Compared to existing technologies that directly drill holes in the wall to fix cable supports, this technical solution does not require damaging the wall structure, effectively solving the problem of laying vertical cables on low-strength walls and ensuring the stability and safety of cable laying. Furthermore, auxiliary fixing connection holes can be opened on the sides of the upper frame 11 and / or the lower frame 12 to provide auxiliary lateral fixing when necessary, further improving the seismic performance of the shaft; however, its main load-bearing function is still independently performed by the vertical frame 1.

[0038] The vertical support 1, the fixing frame 2, and the cable bracket 3 work together as a whole to form a stable, self-supporting, and easy-to-install vertical cable laying channel. These technical features work together to solve the technical problems of vertical cable laying in low-strength wall environments, improving construction efficiency and cable laying reliability.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of this utility model.
