Description

Technical Field

[0001] This invention relates to the field of power line installation technology, and in particular to a compression-type tension clamp for fixing and splicing conductors in transmission lines, which can effectively prevent excessive displacement of jumpers. Background Technology

[0002] In the erection and operation of overhead transmission lines, tension clamps are crucial connecting hardware, mainly used to fix conductors to tension towers or angle towers and bear the full tension of the conductors. Compression-type tension clamps are widely used due to their stable gripping force and low contact resistance. A typical installation process is as follows: First, the outer layer of aluminum wire in the aluminum cable is stripped to expose the steel core. The steel core is then inserted into a steel anchor and crimped. Next, the entire aluminum tube is fitted over the cable and crimped together with the already crimped steel anchor. Finally, a jumper is crimped at the end of the aluminum tube using a current-draining clamp to achieve current conduction and diversion.

[0003] However, in actual operation, jumpers (i.e., drain wires) are only fixed by clamps at both ends, leaving the middle section suspended. Affected by external environmental factors such as wind, icing, and conductor vibration, jumpers experience frequent and irregular swaying. This swaying force concentrates at the crimping point between the jumper and the drain wire clamp, creating a lever-like, repeated bending effect. Over time, this can easily lead to metal fatigue and loosening at the crimping point, and even serious accidents such as jumper breakage, severely threatening the safe and stable operation of the power grid. Existing vibration damping measures, such as adding vibration dampers or damping wires to jumpers, can absorb some vibration energy, but their complex structure and cumbersome installation, and their effectiveness in addressing the stress concentration at the root caused by large-amplitude swaying of the jumper as a whole, are not ideal.

[0004] Therefore, how to provide a tension clamp that is simple in structure, easy to install, and can actively and effectively disperse and transfer the sway force at the end of the jumper, fundamentally protecting the connection point at the root of the jumper and preventing it from loosening and shifting, has become an urgent problem to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a compression-type tension clamp that prevents excessive displacement of jumper wires. It aims to efficiently disperse and transfer the sway force concentrated at the root of the jumper wire through the synergistic effect of a unique connecting component and a sway-reducing component, thereby ensuring the long-term stability and reliability of the connection point.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a compression-type tension clamp for preventing excessive displacement of jumpers, comprising an aluminum tube, a steel anchor, and a drain clamp. One end of the aluminum tube is inserted into the steel anchor, and the other end is fixedly connected to the drain clamp. An aluminum wire passes through the aluminum tube, connects to the steel anchor, and is crimped. The jumper is crimped to the drain clamp. Crucially, it also includes a connecting component and a sway-reducing component. The connecting assembly includes a connecting rod, a stress relief rod assembly, and two connecting clamps. One end of the connecting rod is connected to the aluminum tube via a first connecting clamp, and the other end is connected to the anti-sway assembly. The middle part of the connecting rod is connected to one end of the stress relief rod assembly via a hinge rod, and the other end of the stress relief rod assembly is connected to the crimping point between the drain wire clamp and the jumper via a second connecting clamp. The anti-sway component connects the aluminum tube, the jumper wire, and the connecting component, and is used to disperse and transmit the sway force of the jumper wire to the aluminum tube and the connecting rod.

[0007] Furthermore, the unloading rod assembly includes a front connector, a rear connector, an unloading rod, and a rod sleeve, forming a telescopic elastic damping mechanism. The compression and unloading stroke of the unloading spring can be preset by rotating the adjusting sleeve to adapt to different working conditions.

[0008] Furthermore, the sway reduction assembly includes two sets of symmetrically arranged bow-shaped springs and two spring holders. Through the fine adjustment of the bow-shaped springs and the coordinated constraint of the elastic retainer, the stability and synchronization of the sway reduction energy dissipation process are ensured.

[0009] The compression-type tension clamp provided by this invention for preventing excessive displacement of jumpers has a convenient and orderly installation process: after completing the conventional aluminum tube, steel anchor, and cable crimping, simply fix the connecting clamp one, connecting clamp two, and cable clamp in the preset positions, then connect the modular anti-sway components and stress relief rod assembly through plugging, tightening, or hinged connections, and finally install the bow-shaped spring into the clamp and adjust it. The entire process requires no complicated tools and has low technical requirements for installers.

[0010] During operation, when the jumper cable sways due to factors such as wind vibration, the swaying force is first transmitted through the cable clamp to the spring holder hinged to it. This drives the holder to slide along the connecting rod, causing the two sets of symmetrical bow-shaped springs to arch or straighten in synergistic deformation, efficiently converting the swaying kinetic energy into elastic potential energy and frictional internal energy dissipation. Simultaneously, after being stressed, the connecting rod oscillates slightly around its hinge point with the connecting clamp. This oscillation is transmitted through the hinge to the unloading rod assembly, where it is buffered and absorbed by the unloading spring, forming a two-stage sway reduction and energy absorption process. This continuous process of "dispersion-absorption-transfer" successfully transfers the harmful swaying force originally concentrated at the base of the jumper cable to the robust aluminum tube and connecting rod system, ensuring that the connection point between the jumper cable and the drain clamp remains in a low-amplitude, stable stress state.

[0011] Compared with the prior art, the compression-type tension clamp for preventing excessive displacement of jumpers provided by the present invention has the following outstanding advantages: 1. Simple structure, convenient installation, and low modification cost: The entire anti-sway and sway reduction system consists of purely mechanical modular components such as connecting rods, unloading rod assemblies, bow-shaped springs, and spring holders. It contains no electronic components or hydraulic systems, ensuring reliable structure and ease of manufacturing. During installation, the original pressing process between the aluminum tube and steel anchor remains unchanged. After conventional installation, each module is sequentially fixed and adjusted using clamping, hinged, and tightening methods. No special tools are required throughout the process, minimizing the need for specialized skills from on-site installers, making it suitable for large-scale application in existing line renovations or new line construction.

[0012] 2. Three-level sway reduction, active protection, and source control: This device innovatively constructs a three-level linkage sway reduction system of "vibration pickup - energy dissipation - buffering," completely changing the traditional anti-vibration measures' passive bearing or single energy absorption mode, and achieving source control of stress concentration problems at the root of jumper wires. First stage—remote vibration pickup and elastic energy dissipation: By fixing a wire hoop at a certain distance from the crimping point, the swaying force of the jumper wire is captured in advance, and the swaying kinetic energy is efficiently converted into the elastic potential energy of the spring and the heat dissipation of the friction between the springs by driving the symmetrical bow-shaped spring group to continuously perform "arching-straightening" elastic deformation, which is like setting up an "elastic damping wall" in the path of swaying force propagation.

[0013] The second stage—oscillating buffer and spring energy absorption: The reaction force generated by the deformation of the bow-shaped spring and the thrust of the coil clamp act together on the connecting rod, causing the connecting rod to oscillate slightly around its fixed end in the aluminum tube. This oscillation is accurately transmitted to the unloading rod assembly through the hinge, and is converted into the axial sliding of the unloading rod within the rod sleeve. This repeatedly compresses the unloading spring, converting the oscillation kinetic energy into the elastic potential energy and heat dissipation of the spring, forming a secondary buffer.

[0014] The third stage—force delivery and foundation stabilization: After the energy dissipation of the first two stages, the residual swaying force is finally guided through the connecting rod and the unloading rod assembly to the aluminum tube body with high structural strength and good stability and the crimping point of the drain clamp, respectively. It is jointly borne by the rigid structure of the entire tension clamp, so that the weak connection point at the root of the jumper is always in a low-amplitude and stable stress state.

[0015] These three levels of mechanisms are interconnected and work synergistically to achieve proactive management of the entire process of "dispersion-absorption-transfer" of jumper wire swaying force.

[0016] 3. Highly adjustable, adaptable, and precisely matched: This device has multiple fine adjustment links, which can flexibly adapt to the personalized protection needs of different wire diameters, spans, and climatic conditions.

[0017] Adjustable preload of the bow-shaped spring: By rotating the adjusting screw on the spring holder, the end of the clamped bow-shaped spring can be dragged as a whole to precisely adjust the pre-camber and elastic sensitivity of the entire bow-shaped spring set to match different vibration conditions.

[0018] Adjustable unloading damping stroke: By rotating the adjusting screw on the unloading rod assembly, the pre-compression of the unloading spring and the effective sliding stroke of the unloading rod can be easily changed, thereby adjusting the magnitude of the unloading damping and the response threshold to achieve optimal energy dissipation matching under different vibration intensities.

[0019] 4. Excellent synchronization, stable operation, and reliable safety: The cross-shaped elastic retainer between the two sets of bow-shaped springs, through the coordinated constraint of four sets of retaining springs and retaining rods, ensures that the two sets of bow-shaped springs maintain a high degree of synchronization during deformation. This avoids energy imbalance or unilateral fatigue caused by uneven force distribution, significantly improving the stability and service life of the device. Simultaneously, the convex top structure within the spring holder effectively locks the bow-shaped springs during disassembly or maintenance, preventing them from suddenly springing and causing injury, thus ensuring operational and maintenance safety.

Detailed Implementation

[0022] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] See Figures 1 to 4 This embodiment provides a compression-type tension clamp to prevent excessive displacement of jumper wires. Its main structure includes an aluminum tube 1, a steel anchor 2, and a drain clamp 3. During installation, the aluminum wire is inserted into the aluminum tube 1, and the exposed steel core after stripping the outer aluminum layer is inserted into the cavity of the steel anchor 2. The two are then fixed together using a crimping process. Subsequently, the entire aluminum tube 1 is crimped to the cable with the steel anchor 2 attached, completing the cable gripping and anchoring. The other end of the aluminum tube 1 is fixedly connected to the drain clamp 3 via threads or a tight fit. The end of the jumper wire 4 is inserted into the groove of the drain clamp 3 and crimped to achieve electrical connection.

[0025] The core improvement of this invention lies in the addition of a connecting component 5 and a sway-reducing component 6 that work together.

[0026] The connecting component 5 primarily functions to construct a stable force transmission frame. This component includes a connecting rod 51 serving as the core framework, a set of stress-relieving rod assemblies 52, and two connecting clamps. One end of the connecting rod 51 is clamped and fixed to the outside of the aluminum tube 1 by a first connecting clamp 53. The other end of the connecting rod 51 is connected to the anti-sway component 6. A hinge rod 54 is vertically fixed to the middle of the connecting rod 51, and this hinge rod 54 is hinged to one end of the stress-relieving rod assembly 52. ​​The other end of the stress-relieving rod assembly 52 is tightly fastened to the crimping point between the drain line clamp 3 and the jumper wire 4 by a second connecting clamp 55. This second connecting clamp 55 not only serves as a connection point but also further reinforces the crimping area.

[0027] See Figure 8 The unloading rod assembly 52 specifically includes a front connector 521, a rear connector 522, an unloading rod 523, and a rod sleeve 524. The right end of the front connector 521 is hinged to the hinge rod 54 in the middle of the connecting rod 51, and its left end has an internal threaded hole that screws onto the right end of the unloading rod 523. The left end of the rear connector 522 is hinged to the connecting clamp 55, and its right end has an internal threaded hole that screws onto the outer wall of the left end of the rod sleeve 524. The left end of the unloading rod 523 is inserted into the inner cavity of the rod sleeve 524 and can slide freely axially. An unloading spring 525 is sleeved around the unloading rod 523 and the rod sleeve 524. The left end of the unloading spring 525 abuts against the end face of the adjusting screw sleeve 526, which is screwed onto the outer wall of the rod sleeve 524 via threads, and its right end abuts against the left end face of the front connector 521. By rotating the adjusting screw sleeve 526 on the rod sleeve 524, the pre-compression of the unloading spring 525 can be adjusted, thereby changing the overall stiffness and unloading stroke of the unloading rod assembly 52.

[0028] See Figures 1 to 5 and Figure 9 The sway reduction component 6 is the core component for realizing vibration energy conversion and dissipation. It includes two sets of symmetrically arranged bow-shaped springs 61 and two spring holders 62 for clamping and fixing the ends of these bow-shaped springs. The bow-shaped springs 61 are made of highly elastic metal sheet such as spring steel and are arched. The hinge at the end of the mounting base 621 of one spring holder 62 is directly hinged to the connecting clamp 53 fixed on the aluminum tube 1; the other spring holder 62 is slidably fitted onto the connecting rod 51 through the connecting base 624 on it, and the mounting base 621 can rotate relative to the connecting base 624. The sliding end of the spring holder 62 is hinged to the jumper wire 4 through a wire clamp 63. The clamp 63 is tightly attached to the jumper 4. Its installation position is a preset distance from the crimping point between the jumper 4 and the drain clamp 3, so that the force generated by the vibration and shaking at both ends of the jumper 4 or the drain clamp 3 can be picked up and transmitted by the spring holder 62 of the sway reduction component 6, thereby achieving the purpose of vibration reduction and shaking reduction.

[0029] An elastic retainer 64 is also connected between the two sets of bow-shaped springs 61 to maintain their synchronous deformation. The central hole of the elastic retainer 64 is rotatably mounted on the hinge 54 in the middle of the connecting rod 51, so that it can adaptively adjust its posture according to the deformation of the bow-shaped springs 61.

[0030] See Figure 6 and Figure 7The detailed structure of the reed clamp 62 is shown in detail. Each reed clamp 62 includes a mounting base 621 and an upper clamping plate 622 and a lower clamping plate 623 disposed therein. The mounting base 621 has a slide rail. The upper clamping plate 622 is screwed onto the mounting base 621 by an adjusting bolt 625. Rotating the adjusting bolt 625 can push the upper clamping plate 622 to move slightly along the length of the mounting base 621. A limiting slide head 626 is installed at the bottom of the lower clamping plate 623. The limiting slide head 626 has a non-circular cross section and is slidably disposed in a limiting groove of a corresponding shape in the mounting base 621, so that it can only move up and down and cannot rotate. An adjusting screw 627 is screwed into the bottom of the mounting base 621 and connected to the limiting slide head 626. By rotating the adjusting screw 627, the raising or lowering of the lower clamping plate 623 can be precisely controlled, thereby adjusting the clamping distance between the upper and lower clamping plates.

[0031] Both ends of the bow-shaped spring 61 are stamped with wave-shaped connectors 611. Two sets of bow-shaped springs 61 are placed symmetrically, one above the other, so that the crests and troughs of their respective wave-shaped connectors 611 overlap and are placed together between the upper and lower clamping plates. The lower surface of the upper clamping plate 622 and the upper surface of the lower clamping plate 623 are machined with grooves that match the wave-shaped connectors 611, ensuring surface contact during clamping for a stable and reliable result. During installation, the lower clamping plate 623 is first raised by adjusting screw two 627, pressing the wave-shaped connectors 611 tightly into the grooves of the upper clamping plate 622 to complete the locking. Then, adjusting bolt one 625 is rotated to drag the clamped end of the bow-shaped spring as a whole, causing it to be moderately tightened or loosened along the length of the connecting rod 51, thereby precisely controlling the pre-camber and elastic response sensitivity of the entire set of bow-shaped springs 61.

[0032] In addition, a top screw 628 is screwed onto the mounting base 621, with a convex top head 629 fixed to its front end. When disassembly or readjustment is required, tighten the top screw 628 so that the protruding part of the convex top head 629 pushes into the groove of the wave connector 611, firmly holding the end of the bow-shaped spring. At this time, even if the upper and lower clamps are loosened, the bow-shaped spring 61 will not bounce instantly due to stress release and cause injury.

[0033] See Figure 9 The elastic retainer 64 has a cross-shaped structure, with sliding cavities inside each of its four arm ends. A retaining rod 641 is slidably inserted into each cavity, and a retaining spring 642 abuts against the inner end of the retaining rod 641 and the bottom of the cavity. The four retaining rods are arranged in pairs, with the ends of the two retaining rods 641 in each pair hinged to a card head 643. The card head 643 (which may be made of an elastic material, such as rubber) has an open card slot 644. The size of the slot is just enough to accommodate and constrain the side of the bow-shaped spring 61, while allowing the bow-shaped spring 61 to produce a small sliding displacement within the slot when deformed, thus avoiding stress concentration caused by rigid connection.

[0034] See Figures 1 to 9 The specific installation process in this embodiment is as follows: The first step is to follow the traditional installation process of compression-type tension clamps, and then sequentially complete the crimping of the cable to the steel anchor 2, the overall crimping of the aluminum tube 1 to the steel anchor 2 and the cable, and the crimping of the jumper 4 to the drain clamp 3.

[0035] The second step is to fasten the first connecting clip 53 to the preset position on the aluminum tube 1, fasten the second connecting clip 55 to the crimping point between the drain wire clip 3 and the jumper wire 4, and clamp the wire clamp 63 to the jumper wire 4 at a certain distance from the crimping point.

[0036] Third, assemble the connecting assembly 5. Hinge the front connector 521 of the unloading rod assembly 52 to the hinge 54 in the middle of the connecting rod 51, and hinge the rear connector 522 to the second connecting clamp 55. Hinge the mounting base 621 of one of the spring holders 62 to the first connecting clamp 53, and slide the other spring holder 62 onto the connecting rod 51 via the connecting base 624, and hinge its mounting base 621 to the ear plate on the wire clamp 63. Rotately mount the elastic retainer 64 onto the hinge 54.

[0037] The fourth step is to install the bow-shaped springs 61. Place the two sets of four bow-shaped springs 61 symmetrically, ensuring that the waveform connectors 611 at both ends match, and insert them into the upper and lower clamping plates of the two spring holders 62 respectively. At the same time, ensure that the side of each bow-shaped spring 61 is embedded in the card slot 644 of the corresponding card head 643 of the elastic retainer 64.

[0038] Fifth step, adjust the system. Tighten the adjusting screws 627 of the spring holders 62 at both ends in sequence to lock the wave connector 611; then, according to the required sway reduction stiffness, turn the adjusting bolts 625 to tighten the bow-shaped spring 61. Finally, turn the adjusting sleeve 526 on the unloading rod assembly 52 to set the appropriate unloading damping.

[0039] The specific working process of this embodiment is as follows: During operation, when jumper wire 4 sways, its swaying force pulls the spring holder 62, which is hinged to it, through the wire clamp 63, causing the holder to slide back and forth along the connecting rod 51. This sliding action forces the two sets of bow-shaped springs 61, which are fixed at both ends, to undergo alternating "arching-straightening" deformations, acting like an elastic energy accumulator, converting the swaying kinetic energy into elastic potential energy and dissipating the frictional heat energy between the springs. During this process, the elastic retainer 64, through the coordination of four sets of retaining springs 642, ensures the synchronicity of the deformation of the two sets of bow-shaped springs 61, avoiding energy imbalance. At the same time, the reaction force generated by the deformation of the bow-shaped springs 61 and the thrust transmitted by the wire clamp 63 act together on the connecting rod 51, causing it to oscillate slightly around the hinge point of the connecting clamp 53. This oscillation is transmitted to the unloading rod assembly 52 through the hinge rod 54, manifested as the reciprocating pulling of the unloading rod 523 within the rod sleeve 524, compressing and stretching the unloading spring 525, further dissipating the kinetic energy. Through the synergistic effect of these two-stage anti-sway energy absorption mechanisms, the swaying force ultimately transmitted to the root of the jumper 4 and the drain clamp 3 has been greatly reduced, and the displacement has been effectively limited, thereby ensuring the reliability and safety of the connection point under high-frequency and large-amplitude swaying conditions.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
