Description

Technical Field

[0001] The present application relates to the technical field of cable laying equipment, and in particular to a cable support and a cable laying method. Background Art

[0002] During the cable trench construction phase, construction workers will pre-install and fix the cable brackets at designated locations within the trench. At the same time, after the cable brackets are installed, construction workers will pre-lay traction wires along the cable laying path. By rationally arranging the traction wires within the trench, construction workers hope to use the traction wires as guides during the subsequent cable laying process, thereby smoothly pulling the cables to designated locations. This will reduce the labor intensity of manual laying and improve laying efficiency.

[0003] However, during the actual cable laying process, this construction method of pre-installing cable supports and pre-laying traction wires has exposed a prominent problem. Specifically, because the traction wire has a relatively small diameter, typically only a few millimeters, while the cable has a much larger diameter, this significant difference in diameter makes it easy for the cable end to become obstructed during the traction process as it moves along the traction wire and gradually approaches the cable support. Once the cable end becomes obstructed, not only will the traction process be interrupted, requiring additional time and manpower to troubleshoot, but it may also cause damage to the cable, such as damage to the cable sheath and deformation of the internal conductor, thereby affecting the cable's performance and lifespan, and increasing the overall cost and risk of the project.

[0004] Therefore, how to solve the problem of end obstruction caused by diameter differences during cable laying using traction wires has become one of the key issues that need to be urgently addressed in the current field of cable laying technology. Summary of the Invention

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0042] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0043] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0044] During the cable trench construction phase, construction workers will pre-install and fix the cable brackets at designated locations within the trench. At the same time, after the cable brackets are installed, construction workers will pre-lay traction wires along the cable laying path. By rationally arranging the traction wires within the trench, construction workers hope to use the traction wires as guides during the subsequent cable laying process, thereby smoothly pulling the cables to designated locations. This will reduce the labor intensity of manual laying and improve laying efficiency.

[0045] However, during the actual cable laying process, this construction method of pre-installing cable supports and pre-laying traction wires has exposed a prominent problem. Specifically, because the traction wire has a relatively small diameter, typically only a few millimeters, while the cable has a much larger diameter, this significant difference in diameter makes it easy for the cable end to become obstructed during the traction process as it moves along the traction wire and gradually approaches the cable support. Once the cable end becomes obstructed, not only will the traction process be interrupted, requiring additional time and manpower to troubleshoot, but it may also cause damage to the cable, such as damage to the cable sheath and deformation of the internal conductor, thereby affecting the cable's performance and lifespan, and increasing the overall cost and risk of the project.

[0046] Therefore, how to solve the problem of end obstruction caused by diameter differences during cable laying using traction wires has become one of the key issues that need to be urgently addressed in the current field of cable laying technology.

[0047] In order to overcome the above technical problems, Figures 1-12 As shown, this embodiment provides a cable bracket, comprising:

[0048] The support body 1 includes a plurality of columns 12 and beams 11 arranged in a crisscross pattern, and the columns 12 and beams 11 are separated into a plurality of independent cable holes 13;

[0049] The centering positioning assembly 2 includes a mounting base 21, a lower positioning piece 22, and a torsion spring 24. The mounting base 21 is mounted on the bracket body 1. The upper end of the lower positioning piece 22 is provided with a lower wire clamping groove 221, and the upper end can be rotatably mounted on the mounting base 21. Each cable threading hole 13 is correspondingly installed with a lower positioning piece 22. The torsion spring 24 is connected to the lower positioning piece 22. Under the elastic force of the torsion spring 24, the lower positioning piece 22 remains in an upwardly extended state, so that the lower wire clamping groove 221 is aligned with the center of the cable threading hole 13.

[0050] Among them, the width of the lower wire clamping groove 221 is greater than the width of the traction line 4, so that the traction line 4 can pass through the lower wire clamping groove 221; and the width of the lower wire clamping groove 221 is smaller than the width of the cable 3, so that the end of the cable 3 can push the lower positioning piece 22 to overcome the elastic force of the torsion spring 24 and rotate open.

[0051] Among them, the lower wire clamping groove 221 is located at the upper end of the lower positioning piece 22, and its top side is open, allowing the traction line 4 to be clamped downward, and the two sides of the lower wire clamping groove 221 can form a lateral blockage for the traction line 4 to prevent the traction line 4 from escaping from the lower wire clamping groove 221.

[0052] Specifically, when installing the cable bracket, the traction wire 4 is passed through the cable threading holes 13 on the bracket body 1. Each cable threading hole 13 is correspondingly threaded with a traction wire 4. The traction wire 4 is then inserted into the lower cable clamping groove 221 of the lower positioning piece 22. The lower positioning piece 22 is used to position the traction wire 4 in the middle of the cable threading hole 13. When laying the cable 3, the end of the cable 3 is first connected and fixed to one end of the traction wire 4, and then the traction wire 4 is pulled from the other end to achieve the laying of the cable 3 along the cable channel. During the traction process, when the cable 3 does not contact the lower positioning piece 22, under the elastic force of the torsion spring 24, the lower positioning piece 22 remains in an upwardly extended state, and the traction line 4 remains stuck in the lower wire clamping groove 221, and the traction line 4 can shuttle relative to the lower positioning piece 22; when the end of the cable 3 contacts the lower positioning piece 22, it will push the lower positioning piece 22 to rotate downward. As the lower positioning piece 22 swings downward to a horizontal position, the traction line 4 gradually disengages from the lower wire clamping groove 221, and when the cable 3 passes through the cable hole 13, the heavy cable 3 will press down the lower positioning piece 22, causing it to remain in a downward state. In particular, since the traction line 4 is in the center of the cable hole 13 before the cable 3 contacts the lower positioning piece 22, the end of the cable 3 is also in the center of the cable hole 13, avoiding interference between the end of the cable 3 and the bracket body 1, thereby avoiding the problem of obstruction of the cable 3 during traction.

[0053] The cable support provided in this embodiment, through the design of the centering positioning component 2, ensures that the end of the cable 3 is always located at or near the center of the cable hole 13 during the pulling process, avoiding end obstruction caused by the diameter difference between the cable 3 and the cable support, reducing the time and labor costs of interruption and troubleshooting during the pulling process, and improving the efficiency of laying the cable 3. While avoiding end obstruction, damage to the cable 3 caused by end obstruction is avoided, such as damage to the cable 3 outer sheath or deformation of the internal conductor, thereby ensuring the performance and life of the cable 3 and reducing the overall cost and risk of the project.

[0054] In one embodiment, a plum blossom tube 17 is installed on the bracket body 1. The plum blossom tube 17 can be used to lay small-sized cables such as optical fibers and signal lines to provide reliable support and protection.

[0055] In one embodiment, if Figure 2-Figure 3 As shown, the bracket body 1 includes a cable entry side 15 and a cable exit side 16 that are oppositely arranged. The cable 3 can pass through the cable hole 13 from the cable entry side 15 and pass through the cable hole 13 from the cable exit side 16.

[0056] The mounting seat 21 is mounted on a side of the beam 11 corresponding to the cable outlet side 16 , and the height of the top surface of the mounting seat 21 is lower than the height of the corresponding beam 11 supporting the cable 3 .

[0057] Specifically, during the laying process of the cable 3, when the cable 3 passes through the cable hole 13 from the cable entry side 15 and reaches the cable exit side 16, since the mounting seat 21 is installed on the cable exit side 16 of the crossbeam 11, the cable 3 can push the lower positioning piece 22 to swing forward. This is because the cable 3 moves forward under the action of the traction force, contacts the lower positioning piece 22 located on the cable exit side 16, and applies a thrust, causing the lower positioning piece 22 to overcome the elastic force of the torsion spring 24 and rotate downward. The top surface height of the mounting seat 21 is lower than the corresponding crossbeam 11 support height for the cable 3, ensuring that the crossbeam 11 can stably support the cable 3 after the cable 3 passes through the cable hole 13. At this time, the cable 3 will naturally fall onto the crossbeam 11 due to its own gravity and will not contact the mounting seat 21, thus avoiding friction between the cable 3 and the mounting seat 21 during the traction process.

[0058] Based on the design of this embodiment, the mounting seat 21 is installed on the cable outlet side 16 of the crossbeam 11, so that after the cable 3 passes through the cable hole 13, it can naturally push the lower positioning piece 22 to swing, without additional operation or adjustment. This simplifies the cable 3 pulling process and improves laying efficiency. The design of the top surface height of the mounting seat 21 is lower than the support height of the crossbeam 11 for the cable 3, which avoids friction between the cable 3 and the mounting seat 21. The cable 3 will not be obstructed or worn by the mounting seat 21 during the pulling process, thereby protecting the outer sheath and internal conductor of the cable 3, extending the service life of the cable 3, and reducing engineering costs and risks.

[0059] In one embodiment, a mounting seat 21 is installed on the upper and lower sides of each cable threading hole 13, respectively. In each cable threading hole 13, a lower positioning piece 22 is installed on the mounting seat 21 corresponding to the lower side, and an upper positioning piece 23 is installed on the mounting seat 21 corresponding to the upper side. The lower end of the upper positioning piece 23 is provided with an upper wire clamping groove 231, and the upper end can be rotatably mounted on the mounting seat 21. The upper positioning piece 23 is connected to a torsion spring 24. Under the elastic force of the torsion spring 24, the upper positioning piece 23 remains in a downwardly extended state, so that the upper wire clamping groove 231 is aligned with the lower wire clamping groove 221, so as to limit the traction line 4 from upwardly escaping from the lower wire clamping groove 221;

[0060] Among them, the width of the upper wire clamping groove 231 is greater than the width of the traction line 4, so that the traction line 4 can pass through the upper wire clamping groove 231; and the width of the upper wire clamping groove 231 is smaller than the width of the cable 3, so that the end of the cable 3 can push the upper positioning piece 23 to overcome the elastic force of the torsion spring 24 and rotate open.

[0061] The design of the upper and lower dual positioning plates, through the cooperation of the upper and lower wire retaining grooves 231 and 221, restricts the traction wire 4 from both the upper and lower directions, greatly enhancing the positioning stability of the traction wire 4 in the cable threading hole 13, effectively preventing the traction wire 4 from deflecting or detaching during the traction process, and ensuring the smooth laying of the cable 3. Due to the more stable positioning of the traction wire 4, the traction of the cable 3 caused by the position change of the traction wire 4 is reduced, thereby reducing the time and labor cost of troubleshooting and further improving the efficiency of cable 3 laying.

[0062] In one embodiment, reference Figures 8-10 Between any two adjacent cable holes 13 , the upper positioning piece 23 and the lower positioning piece 22 are installed on the same mounting seat 21 and connected to the same torsion spring 24 .

[0063] Between any two adjacent cable holes 13, the upper and lower positioning pieces 23 and 22 are mounted on the same mounting base 21 and connected to the same torsion spring 24. This design breaks away from the traditional pattern of independent installation of the upper and lower positioning pieces and connection to the torsion spring 24. Instead, it integrates and optimizes the structure. Originally, two mounting bases 21 and two torsion springs 24 were required to control the upper and lower positioning pieces, but this integrated approach reduces the number of mounting bases 21 and torsion springs 24 required. This not only reduces material costs but also reduces the workload during installation, improving installation efficiency.

[0064] In one embodiment, reference Figure 11-12 The mounting seat 21 includes a support shaft 211, and two upper connecting sleeves 232 are provided at the upper end of the upper positioning piece 23; two lower connecting sleeves 222 are provided at the lower end of the lower positioning piece 22, and the upper connecting sleeve 232, the lower connecting sleeve 222 and the torsion spring 24 are respectively sleeved on the support shaft 211;

[0065] Among them, the two lower connecting sleeves 222 are located between the two upper connecting sleeves 232, and the torsion spring 24 is located between the two lower connecting sleeves 222. The torsion spring 24 includes a first torsion arm and a second torsion arm. The first torsion arm abuts the upper positioning plate 23, and the second torsion arm abuts the lower positioning plate 22, so that the upper positioning plate 23 and the lower positioning plate 22 are installed on the same mounting seat 21 and connected to the same torsion spring 24.

[0066] Two upper connecting sleeves 232 are provided at the upper end of the upper positioning piece 23, and two lower connecting sleeves 222 are provided at the lower end of the lower positioning piece 22. The upper connecting sleeves 232, lower connecting sleeves 222, and torsion spring 24 are respectively sleeved onto the support shaft 211. This sleeved connection allows the upper and lower positioning pieces 23 and 22 to rotate around the support shaft 211. The torsion spring 24 is also stably mounted on the support shaft 211, providing elastic force to reset the positioning piece. The two lower connecting sleeves 222 are positioned between the two upper connecting sleeves 232, and the torsion spring 24 is positioned between the two lower connecting sleeves 222. This specific positioning relationship ensures a compact and rational structure, allowing the various components to cooperate with each other and realize the linkage function of the positioning piece. The torsion spring 24 includes a first torsion arm and a second torsion arm. The first torsion arm abuts the upper positioning plate 23, and the second torsion arm abuts the lower positioning plate 22. Through this abutment method, the torsion spring 24 can transfer its own elastic force to the upper positioning plate 23 and the lower positioning plate 22 respectively, thereby realizing their connection with the same mounting seat 21 and linkage with the same torsion spring 24.

[0067] In this embodiment, the upper positioning plate 23, the lower positioning plate 22 and the torsion spring 24 are integrated and installed through the support shaft 211 and the connecting sleeve. The entire installation structure is very compact, and the space occupancy is reduced. At the same time, the socketing and abutment between the various components ensure the stability of the structure, and it can withstand a certain external force during the laying of the cable 3 without loosening or damage.

[0068] The first torsion arm and the second torsion arm of the torsion spring 24 respectively abut against the upper positioning piece 23 and the lower positioning piece 22, thereby achieving good linkage between the upper and lower positioning pieces. During the laying process of the cable 3, the upper and lower positioning pieces can move synchronously according to the traction conditions of the cable 3, more effectively ensuring the stable positioning of the traction line 4, avoiding the position deviation of the traction line 4 caused by inconsistent movement of the upper and lower positioning pieces, and improving the accuracy and stability of the laying of the cable 3.

[0069] In one embodiment, the mounting base 21 includes a clamping base 213, an axle seat 212 and a support shaft 211. The clamping base 213 is clamped to the bracket body 1, the axle seat 212 is arranged along the extension direction of the beam 11 and installed on the clamping base 213, the support shaft 211 is installed on the axle seat 212, and the lower positioning plate 22, the upper positioning plate 23 and the torsion spring 24 are sleeved on the support shaft 211.

[0070] In this embodiment, the clamping seat 213 is fixed to the bracket body 1 by a snap-fit ​​mechanism. Leveraging the characteristics of the snap-fit ​​structure, the mounting seat 21 can be quickly and stably secured to the designated position of the bracket body 1, providing a foundation for the proper functioning of the positioning system during the subsequent laying of the cable 3. The shaft seat 212 is mounted on the clamping seat 213, further defining the installation direction and position of the support shaft 211. This ensures that the support shaft 211 can be positioned along the extension direction of the crossbeam 11 as designed, thereby ensuring that the upper and lower positioning pieces 23 and 22 move in the expected direction during the pulling of the cable 3.

[0071] In one embodiment, reference Figure 10 The column 12 is installed on the side of the beam 11 corresponding to the cable outlet side 16 , and the clamping seat 213 is provided with a superior arc-shaped clamp 2131 , and the clamping seat 213 is clamped to the column 12 through the clamp 2131 .

[0072] During the installation process, the superior arc clamp 2131 of the holder 213 is aligned with the column 12, and then the clamp 2131 is tightly wrapped around the column 12 through certain operations (such as pushing, snapping, etc.). Due to the special shape of the superior arc clamp 2131, it can use its own elasticity or structural characteristics to generate a certain clamping force after wrapping around the column 12, thereby firmly fixing the holder 213 on the column 12. This clamping method utilizes the friction and mechanical constraints between the clamp 2131 and the column 12 to ensure that the holder 213 will not easily loosen or fall off on the column 12.

[0073] In this embodiment, the installation method of the holder 213 being connected to the column 12 through the arc-shaped clamp 2131 is very convenient. There is no need to use additional connectors such as bolts and nuts, nor is there any need for complicated tightening operations. The construction personnel only need to simply snap the clamp 2131 onto the column 12 to complete the installation, which greatly shortens the installation time and improves the installation efficiency of the cable bracket.

[0074] In one embodiment, the crossbeam 11 includes a crossbeam body 111 and a plurality of insulating rollers 112 sleeved on the crossbeam body 111. An insulating roller 112 is correspondingly provided on the bottom side of each cable hole 13, and the cable 3 is supported by the insulating roller 112. The column 12 is vertically connected to the crossbeam body 111, and each insulating roller 112 is separated one by one by the column 12.

[0075] The crossbeam 11 is composed of a crossbeam body 111 and a plurality of insulating rollers 112 . The insulating rollers 112 are sleeved on the crossbeam body 111 . This sleeve connection allows the insulating rollers 112 to rotate flexibly on the crossbeam body 111 , facilitating the movement of the cable 3 .

[0076] When the cable 3 passes through the cable hole 13 and is placed on the crossbeam 11, the insulating roller 112 supports the cable 3. Since the insulating roller 112 can rotate on the crossbeam body 111, when the cable 3 moves on the crossbeam 11, the insulating roller 112 rolls with the movement of the cable 3, converting the sliding friction between the cable 3 and the crossbeam body 111 into rolling friction. This greatly reduces friction and allows the cable 3 to move more smoothly. This makes the cable 3 laying process easier, reduces the labor intensity of construction workers, and also improves the efficiency of cable 3 laying. This resistance-reducing effect is particularly significant when laying cables 3 over long distances. In addition, rolling friction causes less wear on the outer sheath of the cable 3 than sliding friction, effectively protecting the outer sheath of the cable 3 from damage and extending the service life of the cable 3. In addition, the insulating roller 112 itself has excellent insulation properties, which can prevent electrical contact between the cable 3 and the crossbeam body 111, avoiding damage to the cable 3 due to electrical faults.

[0077] The columns 12 separate the insulating rollers 112. During the laying of the cables 3, different cables 3 can be placed in different areas separated by the columns 12. The cables 3 in each area are supported by corresponding insulating rollers 112. In this way, different cables 3 will not be entangled or squeezed with each other, ensuring the independence and safety of the cables 3, and also facilitating subsequent maintenance and management of the cables 3.

[0078] In one embodiment, the beam body 111 includes a main body 1111, and a telescopic head 1112 is inserted at one end or both ends of the main body 1111; the two ends of the beam body 111 are respectively connected to the installation side columns 14, and the installation side columns 14 on both sides are respectively used to be installed on the two opposite side walls in the cable channel; the telescopic head 1112 and the main body 1111 can be relatively telescopic to adapt to the distance between the installation side columns 14 on both sides.

[0079] The crossbeam body 111 is based on the main body 1111 , and the telescopic head 1112 is plugged into one or both ends of the main body 1111 . This plugging method enables the telescopic head 1112 to slide relatively inside the main body 1111 , thereby achieving the adjustability of the length of the crossbeam body 111 .

[0080] When the distance between the two side walls of the cable channel changes, the length of the crossbeam body 111 can be changed by adjusting the relative position of the expansion joint 1112 and the main body 1111. For example, if the cable channel widens, the expansion joint 1112 can be pulled outward from the main body 1111 to a certain distance; if the cable channel narrows, the expansion joint 1112 can be pushed into the main body 1111 to a certain distance, so that the length of the crossbeam body 111 matches the distance between the mounting posts 14 on both sides.

[0081] This adjustment usually relies on the friction between the telescopic head 1112 and the main body 1111 or a simple locking structure (such as bolt fixing, etc.) to achieve relative position fixation, ensuring that the beam 11 can remain stable after the length is adjusted.

[0082] Mounting posts 14 are connected to both ends of the crossbeam body 111. These posts 14 connect the crossbeam 11 to the sidewalls of the cable channel. These posts 14 are mounted on opposing sidewalls of the cable channel, securing the crossbeam 11 within the channel. The posts 14 are secured to the opposing sidewalls of the cable channel using a specific mounting method (e.g., bolts). During installation, the crossbeam body 111 is first adjusted to an appropriate length, and then the posts 14 are mounted on the corresponding sidewalls. This ensures that the crossbeam 11 is stably positioned across the cable channel, providing a support platform for the subsequent laying of the cables 3.

[0083] In this embodiment, during the installation process, construction workers can quickly and conveniently adjust the length of the beam body 111 according to the actual width of the cable trench on site, and then fix the installation side columns 14 to the side walls. This adjustable design reduces the tedious steps of measurement and cutting during the installation process, thereby improving installation efficiency and shortening the project cycle.

[0084] On the other hand, this embodiment provides a method for laying the cable 3 based on the above-mentioned cable support, comprising the following steps:

[0085] Cable bracket installation: Install the cable bracket in the cable channel. At the same time, each cable hole 13 on the cable bracket corresponds to a traction line 4, and the traction line 4 is clamped into the lower clamping groove 221 of the lower positioning piece 22;

[0086] Laying of cable 3: Connect the end of the cable 3 to be laid to one end of the traction line 4, and pull it from the other end of the traction line 4 to drive the cable 3 through the various cable supports in the cable trench until the laying of the cable 3 is completed.

[0087] Based on the cable bracket provided in this embodiment, during the laying process of the cable 3, by adjusting the positioning piece and torsion spring 24 and correctly threading and engaging the traction wire 4, the cable 3 can smoothly push the positioning piece to move when passing through the cable threading hole 13, thereby ensuring smooth passage of the cable 3. At the same time, the provision of the insulating roller 112 reduces the movement resistance of the cable 3 on the crossbeam 11, further ensuring smooth laying of the cable 3 and improving laying efficiency.

[0088] A reasonable laying method for the cable 3 can reduce damage to the cable 3 during the laying process. For example, pre-treating and firmly connecting the cable 3 end to the traction line 4 can avoid the risk of the cable 3 falling off due to loosening or breaking of the connection. Fixing and arranging the laid cable 3 can prevent the cable 3 from being damaged by external interference and enhance the safety of the cable 3.
