Description

Technical Field

[0001] This invention relates to the field of communication equipment technology, specifically a clamp for overhead communication cables. Background Technology

[0002] In the construction of outdoor communication networks, communication cables such as optical fibers and coaxial cables often need to be fixed to utility poles or clamps using clamps for overhead installation. These cables are exposed to the natural environment for extended periods, and the performance of their fixing devices directly affects the stability and lifespan of the line. Currently, commonly used overhead cable clamps generally suffer from the following problems:

[0003] Poor resistance to wind vibration and galloping: Under the action of wind, cables will generate high-frequency light wind vibration or low-frequency galloping. Traditional rigid clamping will cause stress to concentrate at the fixed point. Under long-term action, it is easy to cause wear of cable sheath, fatigue of metal components or even breakage, affecting signal transmission.

[0004] Installation and adjustment are inconvenient, and versatility is low: a set of clamps can usually only fix cables of a specific diameter. When the cable specifications change or multiple cables of different diameters need to be laid simultaneously, multiple sets of clamps need to be replaced or used, making installation cumbersome and inventory management complicated. Adjusting the extension length and angle of the clamps is also quite difficult.

[0005] There is a lack of effective vibration energy dissipation mechanisms: most existing clamps are purely rigid structures, or the vibration reduction function is separated into external dampers, resulting in low integration. They only constrain cable displacement and cannot actively cancel or absorb vibration energy, which is only a temporary solution.

[0006] Limited structural and functional capabilities: Most clamps only perform basic clamping functions and lack intelligent features such as automatic reset after vibration and multi-directional adaptive adjustment, making it difficult to cope with complex working conditions.

[0007] Therefore, developing an overhead cable clamp that integrates vibration reduction, self-adaptation, adjustability, and easy installation is of great significance for improving the reliability, safety, and maintenance convenience of communication lines. Summary of the Invention

[0008] This invention provides a clamp for overhead communication cables, which solves the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A clamp for overhead communication cables includes two arc-shaped housings with several locking mechanisms between them. Each arc-shaped housing has a deflection mounting rod mechanism, an adaptive resonance mechanism, a centering reset mechanism, a telescopic mounting shell mechanism, and a mounting bracket. The mounting bracket is fixedly connected to the arc-shaped housing mechanism, which in turn has several positioning clamping mechanisms. The locking mechanisms connect the two arc-shaped housings, the adaptive resonance mechanism counteracts the deflection vibration of the deflection mounting rod mechanism, the centering reset mechanism resets the deflection mounting rod mechanism, the telescopic mounting shell mechanism adjusts the extension distance of the arc-shaped housing mechanism, and the arc-shaped housing mechanism mounts the positioning clamping mechanisms. The positioning clamping mechanisms secure communication cables of different diameters.

[0011] As a preferred embodiment of the present invention, the locking mechanism includes a first bolt passing through the arc-shaped housing, and the first bolt is threadedly connected to a locking nut.

[0012] As a preferred embodiment of the present invention, the deflection mounting rod mechanism includes a deflection frame fixed to the arc-shaped housing, the deflection frame being fixedly connected to the deflection shaft, the deflection shaft being rotatably connected to the deflection rod, and the deflection rod being provided with a plurality of adjustment holes.

[0013] As a preferred embodiment of the present invention, the adaptive resonance mechanism includes a slider groove provided on the deflection rod, a slider provided in the slider groove, the slider and the deflection rod being slidably connected, a first elastic element being fixedly connected between the slider and the deflection rod, the slider being fixedly connected to the elastic rod, a counterweight being provided outside the elastic rod, the counterweight being threadedly connected to a second bolt, and the second bolt passing through the elastic rod.

[0014] As a preferred embodiment of the present invention, the centering reset mechanism includes an arc-shaped plate fixed on an arc-shaped shell, an arc-shaped groove provided on the arc-shaped plate, the end of the deflection rod located in the arc-shaped groove, the deflection rod and the arc-shaped plate being slidably connected, and the deflection rod being fixedly connected to two symmetrically arranged second elastic members, the end of the second elastic member away from the deflection rod being fixedly connected to the arc-shaped plate.

[0015] As a preferred embodiment of the present invention, the telescopic mounting shell mechanism includes a telescopic shell disposed outside the deflection rod, and the telescopic shell is threadedly connected to two third bolts, which pass through the adjustment hole.

[0016] As a preferred embodiment of the present invention, the mounting arc shell mechanism includes a mounting arc plate fixedly connected to the mounting frame, the mounting arc plate is provided with a mounting groove, and a plurality of positioning holes are provided at equal angles on the mounting arc plate.

[0017] As a preferred embodiment of the present invention, the positioning clamping plate mechanism includes a positioning block disposed in the mounting groove, the positioning block and the mounting arc plate being slidably connected, the positioning block being threadedly connected to a fourth bolt, the fourth bolt passing through a positioning hole, the positioning block being provided with a plurality of rectangular through holes, the rectangular through holes being provided with flexible clamping strips, and the inner side of the flexible clamping strips being provided with a plurality of elastic locking blocks.

[0018] The present invention has the following advantages:

[0019] 1. This overhead communication cable clamp effectively suppresses cable vibration and improves the reliability of the fixing point. Its core advantage lies in its integrated passive vibration damping function. Through a built-in adaptive resonance mechanism, when the cable vibrates at a specific frequency due to wind, the mechanism generates a reverse inertial motion, thereby actively dissipating and offsetting the vibration energy. This design weakens the transmission of vibration to the support structure and clamp body at its source, significantly reducing the risk of fatigue in the cable's metal components and wear on the outer sheath, and extending the service life of the line.

[0020] 2. This device boasts excellent installation flexibility and wide adaptability. On one hand, its deflection mounting rod, combined with a centering reset mechanism, allows the clamping unit to deflect within a certain angle to buffer instantaneous external forces and automatically return to center after the wind load disappears. On the other hand, the telescopic mounting shell mechanism allows for convenient adjustment of the cable clamping unit's extension length. More importantly, the multiple independent positioning clamping plate mechanisms on the mounting shell can be quickly adjusted in layout through sliding and locking. The combination of flexible clamping strips and elastic blocks can securely and without damage hold cables of different diameters, supporting the parallel laying of multiple cables of varying specifications on the same clamp.

[0021] 3. This clamping plate structure boasts a high degree of integration and comprehensive functionality, balancing reliability and convenience. It compactly integrates multiple functional modules, including clamping and fixing, angle buffering, length adjustment, multi-cable clamping, and vibration suppression. The various mechanisms are linked mechanically, requiring no external power source, resulting in a robust structure with low maintenance requirements. The coordinated use of the arc-shaped clamping shell and locking mechanism ensures a secure connection to the support, and the overall design fully considers long-term durability requirements in harsh outdoor environments.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0032] For examples, please refer to Figures 1-6A clamp for overhead communication cables includes two arc-shaped housings 1, with several locking mechanisms 2 between them. Each arc-shaped housing 1 has a deflection mounting rod mechanism 3, an adaptive resonance mechanism 4, a centering reset mechanism 5, a telescopic mounting shell mechanism 6, and a mounting frame 7. The mounting frame 7 is fixedly connected to an arc-shaped housing mechanism 8, which has several positioning clamping mechanisms 9. The locking mechanisms 2 connect the two arc-shaped housings 1, the adaptive resonance mechanism 4 counteracts the deflection vibration of the deflection mounting rod mechanism 3, the centering reset mechanism 5 resets the deflection mounting rod mechanism 3, the telescopic mounting shell mechanism 6 adjusts the extension distance of the arc-shaped housing mechanism 8, and the arc-shaped housing mechanism 8 mounts the positioning clamping mechanisms 9. The positioning clamping mechanisms 9 clamp and fix communication cables of different diameters.

[0033] The locking mechanism 2 includes a first bolt 201 passing through the arc-shaped housing 1, and the first bolt 201 is threadedly connected to a locking nut 202.

[0034] The deflection mounting rod mechanism 3 includes a deflection frame 301 fixed on the arc-shaped housing 1, a deflection shaft 302 fixedly connected to the deflection frame 301, a deflection rod 303 rotatably connected to the deflection shaft 302, and a plurality of adjustment holes 304 provided on the deflection rod 303.

[0035] The adaptive resonance mechanism 4 includes a slider groove 401 on the deflection rod 303, a slider 402 is provided in the slider groove 401, the slider 402 and the deflection rod 303 are slidably connected, a first elastic element 403 is fixedly connected between the slider 402 and the deflection rod 303, the slider 402 is fixedly connected to an elastic rod 404, a counterweight 405 is provided outside the elastic rod 404, the counterweight 405 is threadedly connected to a second bolt 406, and the second bolt 406 passes through the elastic rod 404.

[0036] Specifically, slider 402 is installed in slider groove 401 of deflection rod 303 and can slide along it, with the two connected by first elastic element 403. One end of elastic rod 404 is fixed to slider 402, and a counterweight 405 is sleeved on its outside. The counterweight 405 is locked in place at the desired position by second bolt 406. This mechanism constitutes a mass-spring vibration system, the natural frequency of which can be changed by adjusting the position of counterweight 405 and replacing counterweight 405 to match the target suppressed cable vibration frequency.

[0037] The centering and resetting mechanism 5 includes an arc plate 501 fixed on the arc-shaped housing 1. The arc plate 501 is provided with an arc groove 502. The end of the deflection rod 303 is located in the arc groove 502. The deflection rod 303 and the arc plate 501 are slidably connected. The deflection rod 303 is fixedly connected to two symmetrically arranged second elastic members 503. The end of the second elastic member 503 away from the deflection rod 303 is fixedly connected to the arc plate 501.

[0038] Specifically, the centering and resetting mechanism 5 is used to limit the deflection amplitude of the deflection rod 303 and automatically return it to the center. An arc-shaped plate 501 is fixed to the arc-shaped housing 1, and an arc-shaped groove 502 is formed on it. The end of the deflection rod 303 extends into this groove and can slide. The two ends of the deflection rod 303 are connected to the two ends of the arc-shaped plate 501 via second elastic members 503. When the deflection rod 303 is deflected by an external force, the second elastic member 503 deforms. After the external force disappears, under its restoring force, the deflection rod 303 automatically returns to its initial position in the center of the arc-shaped groove 502.

[0039] The telescopic mounting shell mechanism 6 includes a telescopic shell 601 located outside the deflection rod 303. The telescopic shell 601 is threadedly connected to two third bolts 602, which pass through the adjustment hole 304.

[0040] Specifically, the telescopic shell 601 is fitted over the deflection rod 303. By selecting different adjustment holes 304 and using two third bolts 602 to penetrate the telescopic shell 601 and screw into the selected adjustment holes 304, the telescopic shell 601 can be fixed at different positions on the deflection rod 303, thereby achieving length adjustment.

[0041] The mounting arc shell mechanism 8 includes a mounting arc plate 801 fixedly connected to the mounting frame 7. The mounting arc plate 801 has a mounting groove 802 and a plurality of positioning holes 803 at equal angles. The positioning clamping plate mechanism 9 includes a positioning block 901 disposed in the mounting groove 802. The positioning block 901 and the mounting arc plate 801 are slidably connected. The positioning block 901 is threadedly connected to a fourth bolt 902, which passes through the positioning hole 803. The positioning block 901 has a plurality of pairs of rectangular through holes 903. A flexible clamping strip 904 is provided on the rectangular through holes 903. A plurality of elastic locking blocks 905 are provided on the inner side of the flexible clamping strip 904.

[0042] Specifically, the positioning block 901 is embedded in the mounting groove 802 and can slide along it. By passing the fourth bolt 902 through the selected positioning hole 803 and screwing it into the positioning block 901, the positioning block 901 can be locked at any position on the arc plate. The positioning block 901 has one or more pairs of rectangular through holes 903, through which flexible clamping strips 904 (such as rubber strips) pass to form deformable clamping holes. Multiple elastic locking blocks 905 are molded on the inner side of the flexible clamping strips 904 to increase friction and enhance the self-adaptive clamping effect.

[0043] In addition, since the mounting plate 801 is arc-shaped and the opening of the mounting plate 801 is located on the side, even if the communication cable falls off, the communication cable will not fall to the ground, thus ensuring the safety of the communication cable.

[0044] The workflow of this invention is as follows:

[0045] Installation and fixing: Open the two arc-shaped housings 1, put them on the utility pole or the pre-set clamps, align them and insert multiple sets of first bolts 201, tighten the locking nuts 202, and firmly fix the main body of the clamp to the support.

[0046] Adjusting posture and length: Loosen the third bolt 602, slide the telescopic shell 601 to adjust the extension length, and then tighten it again.

[0047] Configure vibration reduction frequency: Based on the cable type and the local common wind vibration frequency, the second bolt 406 can be loosened, the position of the sliding counterweight 405 on the elastic rod 404 can be adjusted to adjust the natural frequency of the adaptive resonance mechanism 4, and then it can be locked.

[0048] Cable Installation and Fixing: Based on the number, diameter, and layout of the cables to be laid, place the corresponding number of positioning clamping mechanisms 9 into the mounting grooves 802 of the mounting arc plate 801 using their positioning blocks 901. After adjusting the spacing and angle, tighten them with the fourth bolt 902. Press each communication cable into the inner side of the corresponding flexible clamping strip 904 one by one, using the deformation of the flexible clamping strip 904 and the engagement of the elastic locking block 905 to hold them tightly.

[0049] Maintenance: When environmental wind causes cable vibration, the adaptive resonant mechanism 4 activates to dissipate the vibration energy. The deflection mounting rod mechanism 3 may deflect slightly to buffer the instantaneous wind load, and will automatically return to its original position after the wind subsides, thanks to the centering reset mechanism 5. When it is necessary to replace or add cables, simply operate on the corresponding positioning clamp mechanism 9.

[0050] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
