The steel strand bending-free wire clamp drives a movable clamping block to move up and down by setting a connecting rod mechanism to clamp the steel strand. The wire clamp is not only suitable for the protection of overhead ground wires, but also suitable for the protection of optical cables. Since optical cables have a specific minimum bending radius, traditional wedge-shaped wire clamps cannot meet their protection requirements. The technical solution ensures the integrity and performance of optical cables by avoiding excessive bending of optical cables.

[0028] Example
[0029] like Figures 1 to 4 As shown, an embodiment of the present invention provides an overhead ground wire anti-slip backup wire clamp, including a wire clamp for clamping an overhead ground wire 1 that cannot be bent, and the wire clamp also includes a mounting base 2, a connecting rod mechanism, a movable clamp block 3 and a fixed clamp block 4; the connecting rod mechanism is installed on the mounting base 2, the fixed clamp block 4 is installed on the connecting rod mechanism, and the movable clamp block 3 is installed on the movable end of the connecting rod mechanism. The connecting rod mechanism is driven to make the movable clamp block 3 and the fixed clamp block 4 approach or move away from each other to achieve clamping and release of the overhead ground wire 1.
[0030] Preferably, the connecting rod mechanism comprises a connecting rod base 5, a first connecting rod 6, a second connecting rod 7 and a pull ring 8, wherein the connecting rod base 5 is provided with a first sliding slot 9 and a second sliding slot 10, the connecting rod base 5 is fixedly connected to the mounting base plate 2, one end of the second connecting rod 7 is slidably disposed in the first sliding slot 9, and the other end is rotatably connected to the first connecting rod 6, the pull ring 8 is rotatably connected to one end of the second connecting rod 7 slidably disposed in the first sliding slot 9, one end of the movable clamping block 3 is slidably disposed in the second sliding slot 10, and the other end is rotatably mounted on the first connecting rod 6, and the end of the first connecting rod 6 is rotatably connected to the fixed clamping block 4. The connecting rod base 5, the first connecting rod 6, the second connecting rod 7, the fixed clamping block 4 and the pull ring 8 constitute a connecting rod mechanism, and by pulling the pull ring 8 to drive the sliding of the second connecting rod 7 and the rotation of the first connecting rod 6, the movable clamping block 3 and the fixed clamping block 4 are driven to move closer to or farther from each other, thereby clamping or releasing the overhead ground wire 1.
[0031] It is worth mentioning that a line entry channel for passing and clamping the overhead ground wire 1 is formed between the movable clamp block 3 and the fixed clamp block 4, the connecting rod base 5 is fixedly connected to the mounting base plate 2 by a fixing bolt, and the second sliding groove 10 is an arc-shaped groove, and the second connecting rod 7 is driven to move by pulling the pull ring 8 outward, and the second connecting rod 7 drives the first connecting rod 6 to rotate downward, thereby driving the movable clamp block 3 to move toward the fixed clamp block 4 to achieve the fastening and clamping of the overhead ground wire 1, and the mounting rod 11 is connected to the first connecting rod 6 and the movable clamp block 3 at the same time, and its two ends are fastened and limited by nuts, and the two ends of the sliding adjustment rod 12 are limited by nuts. When the movable clamp block 3 moves up and down, the sliding adjustment rod 12 slides back and forth in the second sliding groove 10.
[0032] In some preferred embodiments, a screw locking closure mechanism is also included, and the screw locking closure mechanism includes a fixed plate 13, a movable plate 14 and a fastening screw 15. The fixed plate 13 is fixedly connected to the mounting base plate 2 by a connecting bolt, and the connecting rod mechanism, the movable clamp block 3 and the fixed clamp block 4 are located between the fixed plate 13 and the mounting base plate 2. The movable plate 14 is rotatably connected to the lower edge of the fixed plate 13 by a hinge 16, and the movable plate 14 is fixedly connected to the fixed clamp block 4 by the fastening screw 15. Among them, the movable plate 14 corresponds to the clamping area. The purpose is to facilitate maintenance and work operations with the clamping area by flipping the movable plate 14.
[0033] Furthermore, the fastening screw 15 is a butterfly screw. It should be noted that the fixed clamp block 4 is provided with at least two threaded holes 21 adapted to the fastening screw 15. The number of the threaded holes 21 is the same as the number of the fastening screws 15. The movable plate 14 is fixedly mounted on the fixed clamp block 4 by the fastening screws 15 to close the clamping area.
[0034] In some preferred embodiments, when in use, the movable plate 14 is connected to the fixed clamp block 4 by the two fastening screws 15 to confine the overhead ground wire 1 to the area surrounded by the movable plate 14, the mounting base plate 2, the movable clamp block 3 and the fixed clamp block 4 to prevent the overhead ground wire 1 from sliding laterally out of the movable clamp block 3 and the fixed clamp block 4. When maintenance is required, it is only necessary to remove the two fastening screws 15 and open the movable plate 14 to replace the overhead ground wire 1. By setting the fastening screw 15 to a butterfly screw, the tightening and disassembly of the fastening screw 15 is facilitated.
[0035] In some preferred embodiments, the fixed clamp block 4 is provided with an anti-slip block 17 on one side opposite to the movable clamp block 3, and the two anti-slip blocks 17 are provided with a semicircular arc surface on one side opposite to the fixed clamp block 4, and a plurality of oblique grooves 18 are provided at equal intervals in the semicircular arc surface. By providing the two anti-slip blocks 17 with a semicircular arc surface on one side opposite to the fixed clamp block 4, the movable clamp block 3 and the fixed clamp block 4 are more closely fitted to the overhead ground wire 1 when clamping the overhead ground wire 1, thereby improving the clamping and fixing effect of the movable clamp block 3 and the fixed clamp block 4 on the overhead ground wire 1. Furthermore, since the overhead ground wire 1 is usually a steel strand, a plurality of oblique grooves 18 are provided at equal intervals in the semicircular arc surface, and the overhead ground wire 1 is inserted into the plurality of oblique grooves 18, thereby further improving the clamping and fixing effect of the movable clamp block 3 and the fixed clamp block 4 on the overhead ground wire 1.
[0036] In some preferred embodiments, the fixed clamp block 4 and the movable clamp block 3 are both provided with an interlocking groove, and the anti-sliding block 17 is provided with an interlocking block 19, and the interlocking block 19 cooperates with the interlocking groove. When in use, the interlocking block 19 only needs to be inserted into the interlocking groove to quickly complete the matching installation.
[0037] Among them, one of the anti-sliding blocks 17 is detachably connected to the fixed clamping block 4 through the embedding groove and the embedding block 19, and the other anti-sliding block 17 is detachably connected to the movable clamping block 3 through the embedding groove and the embedding block 19. When the rotation direction of the overhead ground wire 1 to be clamped is opposite, it is only necessary to remove the two anti-sliding blocks 17 and swap the positions of the two anti-sliding blocks 17 to achieve the clamping and fixation of the overhead ground wire 1 with opposite rotation directions. There is no need to additionally produce wire clamps with the oblique grooves 18 in opposite directions, which increases the scope of application of the wire clamp and reduces the manufacturing cost of the wire clamp.
[0038] Furthermore, hook grooves 20 are provided on both sides of the anti-sliding block 17 , and the hook grooves 20 provide a fulcrum when the anti-sliding block 17 is disassembled, so as to facilitate the disassembly of the anti-sliding block 17 .
[0039] In summary, the present invention provides an anti-slip backup wire clamp for overhead ground wires. The steel stranded wire bending-free wire clamp drives the movable clamping block to move up and down by setting a connecting rod mechanism to clamp the steel stranded wire. The wire clamp is not only suitable for the protection of overhead ground wires, but also suitable for the protection of optical cables. Since optical cables have a specific minimum bending radius, traditional wedge-shaped wire clamps cannot meet their protection requirements. The technical solution ensures the integrity and performance of optical cables by avoiding excessive bending of optical cables. Therefore, the wire clamp can be widely used in various transmission lines, including high-voltage, extra-high-voltage and ultra-high-voltage lines, as well as the clamping and connection operations of overhead ground wires and optical cables of different materials and specifications; the overhead ground wire bending-free wire clamp provided by the present invention clamps the slipped steel stranded wire by tightening the connecting rod mechanism, effectively solving the problem The invention solves the problem that traditional wedge-shaped wire clamps cannot be installed on overhead ground wires that are severely corroded or cannot be bent, and provides necessary double protection for these ground wires. At the same time, anti-sliding blocks are provided on the fixed clamping blocks and the movable clamping blocks, and the anti-sliding blocks are provided with serrations. The design of the serrations increases the friction between the upper and lower clamping blocks and the steel strands, further improves the anti-slip ability, and ensures the stability of the ground wire and the optical cable under bad weather or external forces. The invention provides an overhead ground wire bending-free wire clamp, and the wire clamp is also provided with a screw locking closing mechanism, through which the wire can be replaced or repaired (real-time maintenance) in real time as needed. The overall structure of the wire clamp is simple and light, and the installation process is simple and quick, which greatly reduces the installation time and installation cost, and is convenient for daily maintenance and inspection.
[0040] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
