Description

Technical Field

[0001] This invention relates to the field of street code technology, and in particular to a lightweight composite material adjustable universal street code. Background Technology

[0002] In cable laying and engineering construction, cable clamps are a commonly used auxiliary clamping and limiting device, mainly used to fix cables on a specific path or structure to prevent excessive swinging and displacement of the cables due to their own weight, wind vibration or external forces.

[0003] In the prior art, Chinese patent document CN105337233A, entitled "An Adjustable Universal Cable Bracket," describes a cable bracket that is easy to manufacture, highly versatile, applicable to cable fixing at different angles and non-angles, suitable for cables of different diameters, simple to operate, safe, securely clamps the cable, has a long service life, low cost, and is easy to install and disassemble. However, like traditional methods, existing cable brackets mostly adopt traditional rigid metal or plastic structures, typically fixing the cable with bolts or simple elastic elements. While such structures can meet basic limiting requirements, However, it has obvious shortcomings: First, it lacks active response to cable tension or offset, and cannot provide timely support and protection when the cable is under abnormal stress, which can easily cause stress concentration damage; Second, the clamping method is fixed and cannot be automatically adjusted according to different diameters or radii of curvature, which can easily lead to uneven clamping of non-standard cross-section cables; Third, the commonly used metal or rigid materials are heavy and have limited friction performance, which increases the burden of transportation and installation, and makes it difficult to effectively prevent cable slippage and wear during operation. Therefore, this application discloses a lightweight composite material adjustable universal street code. Summary of the Invention

[0004] In view of this, the purpose of this invention is to propose a lightweight composite material adjustable universal street code to solve the problems that existing street codes are mostly rigid metal or plastic structures, with a single fixing method and unable to adapt to different working conditions, and lack timely protection against abnormal stress on cables.

[0005] To achieve the above objectives, the present invention provides a lightweight composite material adjustable universal street code, including a mounting frame, on which a plurality of mounting plates are provided, and a positioning rod is provided through the middle of the plurality of mounting plates. Limiting posts are provided at both ends of the positioning rod. Rotating clamps are rotatably mounted on the positioning rods between the plurality of mounting plates. The mounting frame is also provided with a plurality of sets of auxiliary positioning plates, and each set of auxiliary positioning plates consists of two plates.

[0006] A plurality of lifting and pressing components are respectively disposed on a plurality of sets of auxiliary positioning plates. The plurality of lifting and pressing components correspond to a plurality of rotating clamps. The lifting and pressing components are used to assist in lifting and pressing the cable when it passes through the rotating clamps.

[0007] A self-adjusting component is disposed on a plurality of the lifting and pressing components, and the self-adjusting component is used to automatically adjust the radius when the lifting and pressing components assist the rotating chuck.

[0008] Preferably, the lifting and pressing assembly includes a lifting plate slidably mounted on the opposite side of each set of auxiliary positioning plates. The auxiliary positioning plate has a sliding groove. A rotating sliding column is embedded in one side of the lifting plate. The lifting plate is slidably mounted inside the sliding groove through the rotating sliding column. A second limiting groove is provided on the other side of the lifting plate. A rotating lifting rod is slidably mounted inside the two second limiting grooves. Side plates are provided on both sides of the rotating lifting rod.

[0009] Preferably, a drive rod is provided on both sides of the rotating clamp, and a first limiting groove is provided on one side of the lifting plate. The drive rod slides inside the first limiting groove. When the rotating clamp rotates, it drives the drive rod to move a certain distance inside the first limiting groove. This distance is set as the normal stretching length of the cable. When the rotating clamp continues to rotate, the drive rod drives the side of the lifting plate close to the rotating lifting rod to lift upward, thereby assisting in lifting and compressing the bottom of the cable.

[0010] Preferably, when the lifting plate is raised upward on the side near the rotating lifting rod, the rotating sliding column on the other side of the lifting plate slides downward inside the slide groove.

[0011] Preferably, the self-adjusting assembly includes rotating disks rotatably sleeved on both sides of the rotating lifting rod. A plurality of fixed plates are arranged circumferentially on one side of the rotating disk. Sliding plates are slidably installed inside the plurality of fixed plates. A contact plate is provided on the side of the sliding plate away from the rotating disk. The plurality of contact plates are all arc-shaped. A torsion spring is provided at the rotatable connection between the rotating lifting rod and the two rotating disks.

[0012] Preferably, the rotating disk has a plurality of synchronization grooves arranged in an arc shape, and each of the plurality of sliding plates has a sliding column on one side. The sliding column is slidably installed inside the synchronization groove. When the rotating disk rotates, it drives the plurality of sliding plates to move away from or closer to each other.

[0013] Preferably, an auxiliary connecting plate is embedded between the plurality of contact plates. In the initial state, the plurality of contact plates are pushed outward by the torsion spring. When one of the contact plates is compressed, it will drive the rotating disk to rotate, driving the other contact plates to move inward synchronously.

[0014] Preferably, the contact plate and the auxiliary connecting plate are made of an elastic material with a high coefficient of friction, such as engineering rubber, polyurethane, or a composite material inlaid with ceramic particles, and the surfaces of the contact plate and the auxiliary connecting plate are provided with textures or particles to increase friction.

[0015] Preferably, the rotating chuck is made of a lightweight, high-strength composite material, which can be a fiber-reinforced thermoplastic composite or a carbon fiber composite.

[0016] Preferably, mounting holes are provided on both sides and in the middle of the mounting bracket.

[0017] The beneficial effects of this invention are:

[0018] 1. This lightweight composite material adjustable universal cable clamp, equipped with a lifting and compression component, provides immediate support and compression protection for the cable as it passes through the rotating clamp, based on its tensile state. Specifically, the lifting and compression component consists of a lifting plate, a rotating sliding column, a limiting groove, and a rotating lifting rod. The free-stroke design of the drive rod within the limiting groove ensures smooth passage of the cable under normal tension without interference. When the tension exceeds a set limit, the drive rod pushes the lifting plate, causing its other end to move along the sliding groove, thus lifting the bottom of the cable and preventing sagging or stress concentration. Simultaneously, the side plate provides stable constraint, making the entire lifting process smooth and controllable. This design not only achieves a closed-loop function of zero intervention under normal conditions and precise support under abnormal conditions, but also, through the lever amplification effect, converts the small displacement of the rotating clamp into sufficient lifting displacement, achieving efficient mechanical protection without adding complex drives, thereby significantly improving the safety and reliability of the cable during operation.

[0019] 2. This lightweight composite material adjustable universal clamp, equipped with a self-adjusting component, ensures uniform clamping of the cable from all directions after it is lifted by the lifting and pressing component. The self-adjusting component consists of a rotating disk, sliding plates, contact plates, a synchronous groove, and a torsion spring, forming a forced synchronous adaptive mechanism. When the cable presses against one of the contact plates, the sliding plate behind that contact plate pushes the sliding column to slide along the synchronous groove. The resulting tangential force drives the rotating disk to rotate and transmits the motion to all other sliding plates through geometric constraints. This causes all contact plates to simultaneously and equidistantly converge towards the center, ultimately forming a ring-shaped support that matches the cable's outer diameter, achieving multi-point uniform clamping. Even if the cable has a non-circular cross-section or is placed eccentrically, it can still obtain a balanced clamping force in the entire circumference, avoiding single-point stress damage. In addition, the preload provided by the torsion spring ensures that the mechanism remains open in the initial state for easy cable insertion and automatically resets after the cable is removed, completing a completely passive cyclic operation. At the same time, the clamping force can automatically increase with changes in cable diameter, truly achieving adaptive adjustment. This design not only improves construction efficiency but also effectively enhances the long-term operational reliability of the cable.

[0020] 3. This lightweight composite material adjustable universal clamp significantly optimizes the device's performance and application effect by using a lightweight, high-strength composite material for the rotating clamp and a high-friction coefficient elastic material for the contact plate. The rotating clamp, made of carbon fiber or fiber-reinforced thermoplastic composite material, drastically reduces the overall weight, lessening the burden on the mounting frame and positioning structure, facilitating transportation and installation. It also possesses high strength and wear resistance, ensuring stability under long-term rotation and stress. The contact plate and auxiliary connecting plate are made of engineering rubber, polyurethane, or composite material embedded with ceramic particles, with a textured or granular surface design. This not only significantly increases friction with the cable surface, preventing slippage under wind vibration, self-weight, or external forces, but also achieves a transition from point contact to surface contact through elastic deformation, evenly distributing clamping force and preventing damage to the cable insulation layer. Furthermore, this composite design achieves a comprehensive balance between lightweight, wear resistance, and high friction characteristics, significantly improving cable protection and the overall service life of the device while ensuring long-term reliability.

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0035] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains.

[0036] like Figures 1 to 10 As shown, the lightweight composite material adjustable universal cable clamp includes a mounting frame 1, on which several mounting plates 3 are provided. A positioning rod 4 is provided through the middle of the several mounting plates 3. Limiting posts 5 are provided at both ends of the positioning rod 4. Rotating clamps 6 are rotatably mounted on the positioning rods 4 between the several mounting plates 3. The mounting frame 1 is also provided with several sets of auxiliary positioning plates 7, with two plates in each set. Several lifting and pressing components are respectively provided on the several sets of auxiliary positioning plates 7. The lifting and pressing components correspond to the rotating clamps 6. The lifting and pressing components are used to assist in lifting and pressing when the cable passes through the rotating clamps 6. Self-adjusting components are provided on the several lifting and pressing components. The self-adjusting components are used to automatically adjust the radius when the lifting and pressing components assist the rotating clamps 6. The rotating clamps 6 are made of lightweight high-strength composite material, which can be fiber-reinforced thermoplastic composite material or carbon fiber composite material. Mounting holes 2 are provided on both sides and in the middle of the mounting frame 1.

[0037] During use, the mounting bracket 1 is first fixed to the target work position or support structure through the mounting holes 2 on both sides and in the middle. The positions of several mounting plates 3 are then adjusted according to construction needs to ensure overall stability via the positioning rod 4. Subsequently, the limiting posts 5 at both ends of the positioning rod 4 are locked to prevent the mounting plates 3 from shifting during load-bearing. Simultaneously, multiple clamps mounted on the positioning rod 4 enter a standby state. When a cable needs to be passed through, the operator passes the cable sequentially through the rotating clamp 6. As the cable gradually enters the rotating clamp 6, the lifting and pressing components on the auxiliary positioning plate 7 automatically contact the rotating clamp 6, initiating appropriate lifting and pressing of the cable. During this process, the self-adjusting component... The lifting and pressing components act in real time, automatically adjusting the clamping force and contact radius according to the different diameters and curvature radii of the cables, ensuring that the cables are always under stable and uniform stress. After the cables are fully laid, the lifting and pressing components maintain a certain pressure, fixing the cables in the support of the rotating clamp 6. This ensures that the cables will not fall off under movement or vibration, and also reduces wear on the cable sheath through the lightweight and wear-resistant properties of the composite material clamps. Throughout the process, no manual adjustments are required. All support, limiting, lifting, pressing, and radius matching are completed by the mechanical structure and self-adjusting components of the device, ultimately achieving efficient, stable, and lightweight clamping and protection of the cables, thereby improving construction efficiency and cable operation reliability.

[0038] like Figures 2 to 6 As shown, the lifting and pressing assembly includes a lifting plate 8 slidably mounted on the opposite side of each set of auxiliary positioning plates 7. A sliding groove 10 is provided on the auxiliary positioning plate 7. A rotating sliding column 9 is embedded in one side of the lifting plate 8, and the lifting plate 8 is slidably mounted inside the sliding groove 10 via the rotating sliding column 9. A second limiting groove 13 is provided on the other side of the lifting plate 8. A rotating lifting rod 14 is slidably mounted inside the two second limiting grooves 13. Side plates 23 are provided on both sides of the rotating lifting rod 14. A drive rod 12 is provided on both sides of the rotating clamp 6. A side opening is provided on one side of the lifting plate 8. There is a first limiting groove 11, and the drive rod 12 slides inside the first limiting groove 11. When the rotating chuck 6 rotates, it drives the drive rod 12 to move a certain distance inside the first limiting groove 11. This distance is set as the normal stretching length of the cable. When the rotating chuck 6 continues to rotate, the drive rod 12 drives the lifting plate 8 to lift upward on the side close to the rotating lifting rod 14 to assist in lifting and pressing the bottom of the cable. When the lifting plate 8 is lifted upward on the side close to the rotating lifting rod 14, the rotating sliding column 9 on the other side of the lifting plate 8 slides downward inside the sliding groove 10.

[0039] When the cable passes through the rotating clamp 6, the clamp begins to rotate with the input of external power, driving the drive rods 12 on both sides to move synchronously. Initially, the drive rods 12 slide freely along the first limiting groove 11 on one side of the lifting plate 8. At this time, the lifting plate 8 remains in its initial position, and the cable is only in a normal tension state without any additional interference. As the rotating clamp 6 continues to rotate, when the movement distance of the drive rod 12 in the first limiting groove 11 reaches the preset normal tension length limit, the drive rod 12 continues to move and begins to push the lifting plate 8. One end of the lifting plate 8 is forced to lift upward under the driving action, while the rotating sliding column 9 at the other end slides downward along the sliding groove 10 to form a compliant displacement compensation, ensuring a smooth lifting process. As the lifting plate 8 moves upward, it approaches the rotating lifting rod 1. The side plate 23 gradually lifts the bottom of the cable, providing immediate support and pressure when the cable is overstretched or misaligned, preventing the cable from sagging or experiencing uneven stress. During this process, the side plate 23 provides stable constraints on the rotating lifting rod 14, ensuring a controlled and balanced lifting action. When the cable needs to be released, the rotating clamp 6 moves in the opposite direction or the drive rod 12 exits the end of the first limiting groove 11. The lifting plate 8 returns to its initial position under its own weight and the guiding action of the sliding column. The rotating sliding column 9 returns to its original position in the sliding groove 10, thereby releasing the lifting and pressure on the cable. The entire process achieves a logical closed loop where the cable is undisturbed during normal stretching and receives precise support during overstretching, ensuring that the cable passes smoothly and is reliably protected throughout the entire process of passing through the device.

[0040] The entire lifting plate 8 forms an ingenious first-class lever (such as...) Figure 6 (as shown)

[0041] Fulcrum: The point where the rotating sliding column 9 and the sliding groove 10 meet constitutes the fulcrum of the lever;

[0042] Point of application: The driving rod 12 acts on the end of the first limiting groove 11, which is the point of application of the input force;

[0043] Key point: The side of the lifting plate 8 where the rotating lifting rod 14 is installed is the point of application of the output force;

[0044] When the drive rod 12 pushes the force point and the fulcrum is fixed, the load will be lifted upward. This lever mechanism will amplify the small rotational displacement of the rotating clamp 6 into a sufficient vertical lifting displacement, thereby effectively lifting the cable.

[0045] Furthermore, by sliding the drive rod 12 within the first limiting groove 11, a free stroke is set. The core function of this free stroke is to allow the cable to pass freely through the rotating clamp 6 without triggering any clamping action during the initial stage of cable installation. This provides the operator with operational space for initial positioning and straightening of the cable, effectively avoiding installation difficulties caused by excessive initial resistance and ensuring smooth operation. Moreover, the sliding of the rotating sliding column 9 within the slide groove 10 provides a unique and definite motion trajectory for the entire lifting plate 8, ensuring the stability and repeatability of the action. At the same time, the sliding cooperation between the second limiting groove 13 and the rotating lifting rod 14 accurately transmits and converts the upward tilting action of the lifting plate 8 into the rotational lifting motion of the rotating lifting rod 14, which is a crucial link in the action sequence.

[0046] like Figure 1 , Figure 2 , Figure 5 , Figures 7 to 10 As shown, the self-adjusting assembly includes a rotating disk 15 rotatably sleeved on both sides of the rotating lifting rod 14. A plurality of fixed plates 17 are arranged circumferentially on one side of the rotating disk 15. Sliding plates 18 are slidably installed inside the fixed plates 17. A contact plate 19 is provided on the side of the sliding plate 18 away from the rotating disk 15. The contact plates 19 are all arc-shaped. A torsion spring 22 is provided at the rotational connection between the rotating lifting rod 14 and the two rotating disks 15. A plurality of synchronous grooves 16 are provided on the rotating disk 15. The synchronous grooves 16 are arc-shaped. A sliding column 21 is provided on one side of the sliding plates 18. The sliding column 21 is slidably installed inside the synchronous groove 16. When the rotating disk 15 rotates, it drives the sliding plates 18 to move away from or closer to each other. An auxiliary connecting plate 20 is embedded between the contact plates 19. In the initial state, the contact plates 19 are pushed outward by the torsion spring 22. When one of the contact plates 19 is compressed, it will drive the rotating disk 15 to rotate, driving the other contact plates 19 to move inward synchronously.

[0047] As the lifting rod 14 continues to rise, the outer surface of the cable begins to contact several contact plates 19 of the self-adjusting assembly in its initial unfolded state. The radial pressure exerted by the cable on one or more of these contact plates 19 forces the pressed contact plate 19 to move the sliding plate 18 behind it toward the center. The movement of the sliding plate 18 causes one of its sliding columns 21 to slide inside the arc-shaped synchronous groove 16 opened on the rotating disk 15. The movement of the sliding column 21 within the synchronous groove 16 generates a tangential component force, which drives the rotating disk 15 to rotate around the axis of the lifting rod 14. The rotational motion of the rotating disk 15 is transmitted through the synchronous groove 16 facing all the sliding columns 21 on its upper surface, and simultaneously to the sliding columns 21 on all the other sliding plates 18 arranged circumferentially. 1. Due to the geometric constraints of the synchronization groove 16, all sliding pillars 21 are forced to drive and generate a consistent radial displacement, thereby causing all sliding plates 18 and their contact plates 19 to synchronously and equidistantly converge towards the center. At this time, the auxiliary connecting plate 20 embedded between several contact plates 19 moves accordingly, maintaining the structural integrity of the clamping ring. Finally, all the arc-shaped contact plates 19 together form a clamping ring that matches the outer diameter of the cable, uniformly clamping the cable from all sides to complete the adaptive clamping. During this process, the torsion spring 22 at the connection point is torsionally stored. When the cable is removed, the torsion spring 22 releases energy, driving the rotating disk 15 to rotate in the opposite direction, pushing all sliding pillars 21 and contact plates 19 to move outward synchronously and reset through the synchronization groove 16, waiting for the next working cycle.

[0048] Through the precise cooperation of the rotating disk 15, the synchronization groove 16 and the sliding column 21, this forced synchronization mechanism will drive the rotating disk 15 to rotate when any contact plate 19 is pressed by the cable. This rotation will force the sliding column 21 on all sliding plates 18 to move simultaneously through the synchronization groove 16, thereby driving all contact plates 19 to move towards the center or away from each other synchronously and at equal distances. This means that regardless of whether the cross-section of the cable is circular or elliptical, and regardless of whether it is in the center position, a uniform and all-round clamping force can be obtained, realizing true self-adaptive clamping and effectively avoiding damage to the cable due to excessive stress at a single point.

[0049] Furthermore, the installation of a torsion spring 22 at the connection between the rotating lifting rod 14 and the rotating disk 15 is a crucial step. The preload of the torsion spring 22 provides an initial outward force for all contact plates 19. This design has four advantages: First, it keeps the mechanism open when no cable is installed, facilitating cable insertion; second, it provides an initial preload for clamping, ensuring immediate contact; third, after the cable is removed, it can automatically drive the entire mechanism back to the initial open state, achieving a completely passive automated cycle; fourth, when the cable presses against the contact plate 19, the reverse force generated by the torsion deformation of the torsion spring 22 is converted into a clamping force on the cable, and this clamping force can adaptively increase with the increase of the cable diameter, realizing the self-adjustment of the clamping force.

[0050] The contact plate 19 and the auxiliary connecting plate 20 are made of an elastic material with a high coefficient of friction. The material is set as engineering rubber, polyurethane or a composite material embedded with ceramic particles. The surfaces of the contact plate 19 and the auxiliary connecting plate 20 are provided with textures or particles to increase friction.

[0051] The use of high-friction coefficient elastic materials (such as engineering rubber and polyurethane) for the contact plate 19 and auxiliary connecting plate 20 has the most direct benefit of significantly increasing the static friction with the cable surface. This allows the mechanism to effectively resist the sliding or slight displacement of the cable caused by wind vibration, its own weight, or electromagnetic force after clamping, ensuring absolute stability of the connection. The texture or particles on the surface further disrupt the smoothness of the contact surface, mechanically "biting" the cable surface like tire treads, maximizing the anti-slip capability. The inherent flexibility of the elastic material provides the ability to buffer and adapt to deformation. When the contact plate 19 presses the cable, the material undergoes slight elastic deformation, changing the contact surface from "line contact" or "point contact" to "surface contact," thereby evenly distributing the clamping force to a larger cable surface area. This greatly avoids the stress concentration problem that may be caused by rigid materials, effectively preventing flattening, scratching of the cable sheath, or damage to the internal optical fiber.
