Description

Technical Field

[0001] The present application relates to the technical field of power equipment, and in particular to a cable support for use in a cable trench. Background Art

[0002] In the infrastructure construction of many industries such as electricity and communications, cable trenches serve as key channels for ensuring the safe and orderly laying and operation of various cables. The effective utilization of their internal space has always been a major issue that has received much attention. At present, in the actual application scenarios of cable trenches, the commonly used bracket installation method is a single-sided installation mode. Specifically, construction workers will install brackets for supporting cables on the wall on one side of the cable trench, while a relatively spacious passage is reserved on the other side of the trench. The purpose is to provide sufficient walking space for maintenance personnel so that they can easily enter the trench to carry out work when daily inspections, troubleshooting, repairs and maintenance of the cables are required.

[0003] However, this traditional single-sided mounting method has gradually exposed numerous drawbacks in actual operation, the most prominent of which is the significant waste of space within the cable trench. Since the brackets are installed on only one side, cables can only be laid along that side, leaving the reserved channel on the other side idle most of the time, resulting in extremely low space utilization. This inefficient space utilization model forces the planning and construction of cable trenches to reserve a larger space to accommodate cable laying and subsequent maintenance, which in turn increases the overall trench footprint and volume.

[0004] Therefore, how to improve the bracket installation method in the cable trench, improve space utilization, reduce space waste, and achieve miniaturization of the trench has become a key technical problem that needs to be solved urgently in the current field of cable trench construction.

[0006] To achieve the above objectives, the present application proposes a cable support for use in a cable trench, comprising:

[0007] Two support columns are symmetrically arranged, and the two support columns are respectively used to be fixed to two opposite side walls of the cable trench;

[0008] At least one supporting beam is used to support the cable; both ends of the supporting beam are respectively connected to the two supporting columns, and the supporting beam is a telescopic beam structure, and the supporting beam can adapt to the distance between the two supporting columns through its own telescopic structure.

[0009] In one embodiment, the support beam is provided with a transverse insulating rotor, which is rotatable relative to the support beam and is used to support the cable.

[0010] In one embodiment, at least one middle partition column is further included, and a plurality of the support beams are arranged in parallel up and down; the middle partition column extends in the up and down direction and is connected to each of the support beams.

[0012] In one embodiment, the support beam comprises a main support tube and end connectors, wherein:

[0013] One end of the main support tube is retractably connected to the end connector, the end connector is fixedly connected to one of the support columns, and the end of the main support tube away from the end connector is fixedly connected to the other support column;

[0014] Alternatively, the two ends of the main support tube are telescopically connected with the end connectors, and the two end connectors at both ends are fixedly connected to the support columns on both sides.

[0015] In one embodiment, a push rod extending radially outward is provided in the middle of the end connector, and the push rod can push the end connector to expand and contract relative to the main support tube.

[0016] In one embodiment, the support column is a square tube structure extending up and down, and is provided with an axially perpendicular plug hole and a fastening hole. The support beam is inserted into the plug hole, and the fixed connecting part passes through the support beam through the fastening hole to achieve a fixed connection between the support column and the support beam.

[0017] In one embodiment, a support sleeve is further provided in the insertion hole of the support column, the support beam is inserted into the support sleeve, and the support column supports the support beam through the support sleeve.

[0018] In one embodiment, a mounting member is fixed to the side wall of the support column, and a mounting hole is provided on the mounting member. The mounting member can be connected with the expansion screw in the cable trench to achieve the installation of the support column.

[0019] In one embodiment, a bottom beam is further included, which is arranged parallel to the lowest side of all the supporting beams, and long connecting holes are provided at both ends of the bottom beam; connecting plates are fixedly provided on the opposite sides of the two supporting columns, and threaded connecting parts pass through the connecting plates and the long connecting holes of the bottom beam to connect and lock the bottom beam with the connecting plates on both sides.

[0020] The beneficial effect of this application is that by installing the cable bracket across the entire width of the cable trench, the space inside the cable trench is fully utilized and space waste is reduced. This allows a smaller cable trench to be used under the same cable laying requirements, which is conducive to the miniaturization of the cable trench, thereby saving land resources and reducing construction costs.

[0021] The telescopic beam structure of the support crossbeam compensates for dimensional errors in the cable trench, ensuring that the two support columns can be securely installed on the two sides of the cable trench.

[0037] In the infrastructure construction of many industries such as electricity and communications, cable trenches serve as key channels for ensuring the safe and orderly laying and operation of various cables. The effective utilization of their internal space has always been a major issue that has received much attention. At present, in the actual application scenarios of cable trenches, the commonly used bracket installation method is a single-sided installation mode. Specifically, construction workers will install brackets for supporting cables on the wall on one side of the cable trench, while a relatively spacious passage is reserved on the other side of the trench. The purpose is to provide sufficient walking space for maintenance personnel so that they can easily enter the trench to carry out work when daily inspections, troubleshooting, repairs and maintenance of the cables are required.

[0038] However, this traditional single-sided mounting method has gradually exposed numerous drawbacks in actual operation, the most prominent of which is the significant waste of space within the cable trench. Since the brackets are installed on only one side, cables can only be laid along that side, leaving the reserved channel on the other side idle most of the time, resulting in extremely low space utilization. This inefficient space utilization model forces the planning and construction of cable trenches to reserve a larger space to accommodate cable laying and subsequent maintenance, which in turn increases the overall trench footprint and volume.

[0039] Therefore, how to improve the bracket installation method in the cable trench, improve space utilization, reduce space waste, and achieve miniaturization of the trench has become a key technical problem that needs to be solved urgently in the current field of cable trench construction.

[0040] In order to overcome the above technical problems, such as Figures 1-8 As shown, an embodiment of the present application provides a cable support for use in a cable trench, comprising:

[0041] Two support columns 1 are symmetrically arranged, and the two support columns 1 are respectively used to be fixed on two opposite side walls of the cable trench 6;

[0042] At least one supporting beam 2 is used to support the cable; both ends of the supporting beam 2 are respectively connected to two supporting columns 1, and the supporting beam 2 is a telescopic beam structure, and the supporting beam 2 can adapt to the distance between the two supporting columns 1 through its own telescopic structure.

[0043] The cable rack of this embodiment features two symmetrical support columns 1, ensuring greater overall stability and more even distribution of forces. These columns, fixed to opposing sidewalls of the cable trench 6, provide a stable foundation for the entire cable rack. Much like the pillars of a building, they bear the weight of the cables above and any other external forces. During installation, the columns 1 are securely fastened to the sidewalls of the cable trench 6 using specialized fixings (such as expansion bolts). This prevents loosening or displacement during cable installation and operation, ensuring the reliability and safety of the cable rack.

[0044] At least one support beam 2 is provided, and its primary function is to support the cables. In practical applications, multiple support beams 2 can be flexibly provided based on the number of cables and their routing requirements to meet the cable support requirements in different scenarios. The support beam 2 utilizes a telescopic beam structure, meaning it can be adjusted to extend and retract based on the distance between the two support columns 1. This structure typically consists of multiple relatively slidable components, such as an inner sleeve and an outer sleeve.

[0045] During installation of the cable support of this embodiment, the two support columns 1 are respectively installed on the two opposite side walls of the cable trench 6, so that the entire cable support is installed completely across the entire width of the cable trench 6. Compared with the traditional single-sided installation method, this installation method fully utilizes the previously unused space inside the cable trench 6, expanding the cable laying area from a single side to the entire trench width, greatly improving space utilization. Since the cable trench 6 is generally a cement-cast structure, certain dimensional accuracy errors are inevitable during the construction process. When the two support columns 1 are fixed to the two side walls of the cable trench 6, the distance between the two side walls may not be completely consistent with the design value. At this time, the telescopic beam structure of the support beam 2 plays an important role. It can adapt to the actual distance between the two support columns 1 through its own expansion and contraction, ensuring that the two ends of the support beam 2 can be reliably connected to the support columns 1 on both sides, thereby compensating for the installation difficulties caused by the dimensional error of the cable trench 6 and ensuring the reliability of the cable support installation.

[0046] The cable holder of this embodiment is installed in the cable trench 6. When the prefabricated cable trench 6 is cast on site or embedded in advance, the cable holder is simultaneously installed in the cable trench 6 and then the top structure is cast. In order to facilitate the later laying of cables, a traction wire can be arranged on the cable holder in advance along the extension direction of the cable trench 6 when the cable holder is installed. When the cable is laid later, the cable can be directly fixed to one end of the traction wire, and then the cable can be laid by pulling from the other end of the traction wire.

[0047] An automatic inspection device is usually provided in the cable trench 6. When the automatic inspection device reports a fault, the staff can cut the cable from the two adjacent manhole covers at the fault location and pull it out for repair. After the repair, the cable can be laid back and connected. In order to facilitate the later re-laying of the repaired cable, a traction wire needs to be fixed to the cut end when pulling out the cut cable, and the traction wire can be used to pull the cable back for laying later.

[0048] The cable bracket provided in this embodiment can achieve at least the following beneficial effects:

[0049] By installing the cable bracket across the entire width of the cable trench 6, the space inside the cable trench 6 is fully utilized and space waste is reduced. This allows a smaller cable trench 6 to be used under the same cable laying requirements, which is conducive to miniaturization of the cable trench 6, thereby saving land resources and reducing construction costs.

[0050] The telescopic beam structure of the support crossbeam 2 compensates for dimensional errors in the cable trench 6, ensuring that the support columns 1 on either side can be securely mounted to the walls of the trench 6. This prevents problems with the bracket being improperly installed or unstable after installation due to dimensional errors, improving the installation quality and reliability of the cable bracket. Reliable installation ensures cable stability during operation, reduces cable failures caused by loose or displaced brackets, and improves the operational safety of power or communication systems.

[0051] Furthermore, the telescopic support beam 2 provides the cable support with a degree of flexibility, adapting to cable trenches 6 of varying widths. Whether for new construction or renovation projects, the cable support can be adjusted to the actual size of the cable trench 6, eliminating the need for custom-made support beams of varying specifications, reducing production costs and construction complexity.

[0052] In one embodiment, reference Figure 4 The supporting crossbeam 2 is provided with a transverse insulating rotor 23, which can rotate relative to the supporting crossbeam 2 and is used to support the cable.

[0053] The primary function of the transverse insulating rotor 23 is to support the cable. When the cable is laid on the cable support, it rests on the transverse insulating rotor 23. Because the transverse insulating rotor 23 can rotate relative to the supporting crossbeam 2, when the cable is subjected to external forces (such as dragging by a worker), the cable can slide on the transverse insulating rotor 23, driving its rotation. This reduces friction between the cable and the supporting structure. This low-friction movement prevents damage to the cable's insulation layer due to long-term high friction, thereby extending the cable's service life. Furthermore, during cable laying, construction workers can more easily drag the cable because the rotation of the transverse insulating rotor 23 reduces resistance during the cable laying process. This not only improves construction efficiency but also reduces the workload of construction workers.

[0054] In one embodiment, reference Figure 3 , and also includes at least one middle partition column 3, and multiple supporting beams 2 are arranged in parallel up and down; the middle partition column 3 extends along the up and down direction and is connected to each supporting beam 2.

[0055] At least one central partition 3 is provided, and the number of partitions can be flexibly determined based on factors such as the width of the cable trench 6, the amount of cables to be laid, and the required overall structural stability. When the cable trench 6 is wider or needs to support a large number of cables, the number of central partitions 3 can be appropriately increased to enhance the support's load-bearing capacity and stability. In this embodiment, the central partitions 3 extend vertically. This vertical arrangement effectively connects and supports the parallel support beams 2, forming a stable overall frame structure for the entire cable support.

[0056] On the other hand, the upper and lower middle partition columns 3 can laterally divide the area above the supporting beam 2 into multiple independent areas, and a cable can be laid separately in each area. In this way, in addition to laying the cables in layers up and down, the cables can also be separated from each other laterally. This can avoid the problem of mutual friction and entanglement during the laying of cables. More importantly, it can keep the cables spaced apart to reduce mutual interference between the cables.

[0057] In one embodiment, reference Figure 6 A vertical insulating rotor 31 is sleeved on the middle partition column 3, and the vertical insulating rotor 31 can rotate relative to the middle partition column 3.

[0058] The vertical insulating rotor 31 is sleeved on the middle partition column 3. It is distributed along the axial direction of the middle partition column 3 and can rotate freely on the middle partition column 3. Its material is usually selected from materials with good insulation properties, such as engineering plastics, rubber composite insulation materials, etc., to effectively isolate the current, prevent leakage between cables or between cables and brackets, and ensure the safety of cable operation.

[0059] Similarly, when the cable is laid on the cable bracket, it may come into contact with the vertical insulating rotor 31. Since the vertical insulating rotor 31 can rotate relative to the middle partition column 3, when the cable is displaced or deformed by external force, the cable can drive the vertical insulating rotor 31 to rotate. This rotational motion can reduce the friction between the cable and the bracket, making the cable smoother during movement and avoiding damage to the cable due to excessive friction.

[0060] In one embodiment, the support beam 2 includes a main support tube 21 and end connectors 22, wherein:

[0061] One end of the main support tube 21 is retractably connected to an end connector 22, which is fixedly connected to one of the support columns 1, and the end of the main support tube 21 away from the end connector 22 is fixedly connected to the other support column 1;

[0062] Alternatively, both ends of the main support tube 21 are telescopically connected with end connectors 22, and the two end connectors 22 at both ends are fixedly connected to the support columns 1 on both sides.

[0063] In this embodiment, the main support tube 21 is the main structure supporting the crossbeam 2 and performs the primary supporting function for supporting the cables. It is typically made of materials with a certain strength and rigidity, such as steel or aluminum alloy, to ensure it can withstand the weight of the cables as well as other possible external forces, such as stress caused by the cables' own thermal expansion and contraction, and external vibrations. The primary function of the end connector 22 is to securely connect the main support tube 21 to the support column 1. One end of the connector is retractably connected to the main support tube 21, while the other end is securely connected to the support column 1 via a specific fixing method (such as bolting or welding), ensuring the stability of the entire cable support structure.

[0064] In one embodiment, reference Figure 4 A push rod 221 extending radially outward is provided in the middle of the end connector 22 , and the push rod 221 can push the end connector 22 to extend or retract relative to the main support tube 21 .

[0065] Push rod 221 is located in the middle of end connector 22 and extends radially outward, meaning that push rod 221 is oriented perpendicular to the axial direction of end connector 22. The shape of push rod 221 can be designed based on actual needs, with common shapes including cylindrical and flat rod-like shapes. Its size should be convenient for the operator to apply thrust. Push rod 221 primarily serves as an operating point. External force acting on push rod 221 facilitates the telescopic movement of end connector 22 within main support tube 21, thereby adjusting the length of support beam 2.

[0066] The design of the push rod 221 allows the operator to easily adjust the length of the support beam 2 by pushing or pulling the push rod 221 without having to directly touch the connection between the end connector 22 and the main support tube 21. Compared with the traditional method of requiring tools or complex operations to perform telescopic adjustment, it greatly simplifies the operation process and improves work efficiency.

[0067] In one embodiment, reference Figure 7-Figure 8 The support column 1 is a square tube structure extending up and down. The support column 1 is provided with an axially perpendicular plug hole 11 and a fastening hole 12. The support beam 2 is inserted into the plug hole 11, and the fixed connector 13 passes through the support beam 2 through the fastening hole 12 to achieve a fixed connection between the support column 1 and the support beam 2.

[0068] The support column 1 adopts a square tube structure extending up and down. The square tube has good strength and stability, and can withstand the weight of components such as cables and support beams 2 as well as possible external forces. Moreover, it is hollow, consumes less materials, and has low cost. It is usually made of steel to ensure that it has sufficient load-bearing capacity and durability.

[0069] The support column 1 is provided with an axially perpendicular plug hole 11 and a fastening hole 12. The plug hole 11 provides an installation position for the support beam 2 so that the support beam 2 can be inserted therein; the fastening hole 12 is used to cooperate with the fixed connector 13 to achieve a fixed connection between the support column 1 and the support beam 2.

[0070] When the support beam 2 is inserted into the insertion hole 11 of the support column 1, the inner wall of the insertion hole 11 contacts the outer surface of the support beam 2, restricting the position of the support beam 2 so that it can only move axially along the insertion hole 11. After the fixing member 13 (such as a bolt) is passed through the fastening hole 12 in the support column 1 and the support beam 2, and the nut is tightened, the fixing member 13 will restrict the axial freedom of movement of the support beam 2, thereby completely securing the support beam 2.

[0071] The support beam 2 and support column 1 utilize a plug-in connection. Assemblers simply insert the support beam 2 into the plug-in hole 11 to complete initial installation, eliminating the need for complex positioning and securing operations. Subsequently, the fixed connector 13 and fastening holes 12 are used for fastening. The entire installation process is simple and quick, significantly reducing assembly time and improving work efficiency. Furthermore, the fastening action of the fixed connector 13 and fastening holes 12 creates a secure connection between the support column 1 and the support beam 2. This connection method can withstand significant tensile and shear forces, ensuring that the support beam 2 will not loosen or fall off during cable operation due to factors such as the weight of the cable or external impact, thereby ensuring the stability and reliability of the entire cable support structure.

[0072] In one embodiment, reference Figure 8 A support sleeve 4 is also provided in the insertion hole 11 of the support column 1, and the support beam 2 is inserted into the support sleeve 4. The support column 1 supports the support beam 2 through the support sleeve 4.

[0073] Specifically, the support column 1 utilizes a square tube structure, which itself has four thin walls. However, when actually supporting the support beam 2, typically only two opposing thin walls directly contact the support beam 2 and provide support, resulting in a relatively small support area. Therefore, in this embodiment, a support sleeve 4 is provided. The support sleeve 4 is disposed within the insertion hole 11 of the support column 1, and the support beam 2 is inserted into the support sleeve 4. The presence of the support sleeve 4 changes the contact method between the support beam 2 and the support column 1, from direct contact between the support beam 2 and the thin walls of the support column 1 to contact between the support beam 2 and the support sleeve 4, with the support sleeve 4 then transmitting force to the support column 1.

[0074] In this embodiment, since the support sleeve 4 increases the support area, the force transmitted to the support column 1 by the support beam 2 can be more evenly dispersed, reducing the local stress on the support column 1. This helps to avoid deformation or damage of the support column 1 due to stress concentration, and improves the stability of the entire support structure.

[0075] In one embodiment, a mounting member 14 is fixed to the side wall of the support column 1 , and a mounting hole 141 is provided on the mounting member 14 . The mounting member 14 can be connected with the expansion screw in the cable trench 6 to achieve the installation of the support column 1 .

[0076] Mounting member 14 is fixed to the side wall of support column 1. Its specific location can be determined based on actual installation needs and design requirements. For example, it can be evenly distributed at different heights on the side wall of support column 1 to ensure installation stability. Mounting member 14 can be flat, block-shaped, or other suitable shapes, as long as it can meet the function of connecting with the expansion screw. Mounting member 14 is provided with mounting hole 141. The size and shape of mounting hole 141 must match the size and shape of the expansion screw. It is typically a circular hole with a diameter determined by the specifications of the expansion screw to ensure that the expansion screw can smoothly pass through mounting hole 141 and achieve a secure connection.

[0077] In this embodiment, a firm connection is formed between the expansion screw and the mounting member 14 and the wall of the cable trench 6, which can provide sufficient connection strength to ensure that the support column 1 can remain stable under various working conditions. Even when subjected to a large external force, the expansion screw will not loosen or fall off easily, thereby ensuring the safety and reliability of the cable support system.

[0078] In one embodiment, a bottom beam 5 is further included, which is arranged parallel to the lowest side of all supporting beams 2, and long connecting holes 51 are provided at both ends of the bottom beam 5; connecting plates 15 are fixedly provided on the opposite sides of the two supporting columns 1, and threaded connectors pass through the connecting plates 15 and the long connecting holes 51 of the bottom beam 5 to connect and lock the bottom beam 5 with the connecting plates 15 on both sides.

[0079] The bottom beam 5, parallel to the lowest of all supporting beams 2, reinforces and stabilizes the overall support structure. It is typically a long, strip-shaped structure, with its length determined by the cable rack's span and actual requirements. Its material, such as steel, matches that of the supporting columns 1 and supporting beams 2 to ensure sufficient strength and rigidity. Connecting holes 51 are typically provided at each end of the bottom beam 5. These holes are typically long, strip-shaped holes, their length generally aligning with that of the bottom beam 5. This design facilitates installation and adjustment.

[0080] Specifically, the long connecting hole 51 provides space for adjusting the relative position between the bottom beam 5 and the support column 1. During the installation process, the position of the bottom beam 5 in the length direction of the long connecting hole 51 can be adjusted according to actual conditions, so that the bottom beam 5 can be accurately installed in the predetermined position, ensuring that the horizontality and verticality of the entire cable support system meet the design requirements. When the position is determined, the bottom beam 5 is fixed to the connecting plate 15 by threaded connectors to achieve precise positioning of the bottom beam 5.

[0081] In this embodiment, the bottom beam 5 is arranged at the lowest side of all the supporting beams 2 and is connected to the supporting column 1 through the connecting plate 15, thereby increasing the lateral and longitudinal stability of the entire cable support system.

[0082] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of protection of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
