Description

Technical Field

[0001] The present application relates to the field of electric power fittings, and in particular to a split wedge-shaped tension clamp. Background Art

[0002] The wedge-shaped wire clamp can eliminate the bending stress and compressive stress caused by weight in the same direction as the dynamic stress of the conductor's breeze vibration, and the conductor's compressive stress caused by its grip strength is evenly distributed around the conductor, so that the inner and outer aluminum strands are tightly together, and each strand of the conductor is subjected to the same force, which greatly reduces the damage caused by conductor vibration;

[0003] The wedge-shaped tension clamp is used to install steel strands, fasten overhead ground wires and guy wires on towers, and uses the splitting force of the wedge to lock the steel strands in the clamp.

[0004] However, the wedge-shaped tension clamp uses the gravity of the conductor to pull the wedge block therein, causing the two wedge surfaces to displace relative to each other, so that the extrusion and reaction forces can be stable. However, most of the existing ones are fixed clamps. After long-term use, the two components are easily stuck and are not easy to remove, which makes maintenance inconvenient. Moreover, after getting stuck, it can only be replaced as a whole, which is not only troublesome to reinstall, but also costly.

[0005] Therefore, it is necessary to design a split wedge-shaped tension clamp that has a stable structure, is easy to disassemble and replace, and can firmly fix the cable. Utility Model Content

However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0030] In the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are connected to form a whole only through a connecting structure. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0031] like Figures 1 to 5 As shown, the present application provides a split wedge-shaped tension clamp for clamping conductors, which is easy to install and maintain, and can quickly disassemble and adjust the wedge-shaped wire core and the wire clamp shell.

[0032] In one embodiment of the present application

[0033] like Figure 1-Figure 2 As shown: a split wedge-shaped tension wire clamp, including a wire clamp body 1, the wire clamp body 1 including a wire clamp shell 11 and a wedge-shaped wire core 2, a wedge-shaped accommodating cavity 100 is provided in the wire clamp shell 11, the wedge-shaped wire core 2 is in the wedge-shaped accommodating cavity 100, the shapes of the wedge-shaped wire core 2 and the accommodating cavity 100 are consistent, the wedge-shaped wire core 2 is mainly subjected to the pulling force provided by the direction of gravity or its component force of gravity, and the fixed pulling force of the wire clamp shell 11 on the wedge-shaped wire core 2 is opposite to the direction of gravity. Therefore, through the mutual squeezing and clamping between the wedge-shaped wire core 2 and the wire clamp shell 11, the wedge-shaped wire core 2 and the wire clamp shell 11 will be pulled tighter.

[0034] An inlet hole 21 and an outlet hole 22 are provided on the wedge-shaped wire core 2. In order to facilitate the installation or removal of the entire wedge-shaped wire core 2, a sliding groove 12 is opened on the wire clamp shell 11. The sliding groove 12 is connected to the wedge-shaped accommodating cavity 100. An installation auxiliary block 23 is provided on the side wall of the wedge-shaped wire core 2. The lower end of the installation auxiliary block 23 is located in the sliding groove 12. The installation auxiliary block 23 slides up and down along the sliding groove 12, which not only guides the wedge-shaped wire core 2, but also limits the installation position of the wedge-shaped wire core 2, making the installation faster and more convenient.

[0035] The installation auxiliary block 23 can be set as an integrally formed structure with the wedge-shaped wire core 2. The position of the wedge-shaped wire core 2 can be adjusted and moved by only pushing the installation auxiliary block 23 from the side, without adjusting the wedge-shaped wire core 2 at both ends of the wedge-shaped accommodating cavity 100 in the wire clamp shell 11, which is more convenient to operate.

[0036] In order to facilitate adjustment, an adjustment hole 230 is provided on the installation auxiliary block 23. By hooking or other tools in the adjustment hole 230, the entire wedge core 2 can be quickly removed by using the lever principle.

[0037] Adjustment devices 5 are provided on both sides of the sliding groove 12, and the adjustment devices 5 are used to adjust the tightness between the wire clamp shell 11 and the wedge-shaped wire core 2.

The left connecting rod 3 and the right connecting rod 4 and the wire clamp housing 11 are designed as a split structure, and the split structure simplifies the manufacturing method of the main structure, so that it can be produced and processed by a forging process. The detachable clamping method is not only conducive to the whole device being split into multiple small parts for carrying, but also allows the wire clamp device and the wire to be quickly replaced.

[0039] A fastener 6 is connected between the left connecting rod 3 and the right connecting rod 4, and the entire wire clamp is connected to a specific position through the fastener 6.

[0040] The wire clamp housing 11 includes a left half 111 and a right half 112 , the bottom end of the left half 111 is connected to the bottom end of the right half 112 , and the upper end of the left half 111 and the upper end of the right half 112 are separated by the sliding groove 12 .

[0041] like Figure 2-3 As shown: In the present invention, the adjustment device 5 includes two adjustment components, each of which is arranged above the sliding groove 12, and one end of each adjustment component is connected to the left half 111, and the other end of each adjustment component is connected to the right half 112.

[0042] The adjustment assembly includes a first connecting plate 51 and a second connecting plate 52 . The first connecting plate 51 is fixed to the left half 111 , and the second connecting plate 52 is fixed to the right half 112 .

[0044] As a further configuration, the tightening member 53 includes a hexagonal bolt 531 and a fastening nut 532. After the wedge-shaped wire core 2 and the wire clamp shell 11 are clamped together, the hexagonal bolt 531 and the fastening nut 532 are tightened to make the wedge-shaped wire core 2 and the wire clamp shell 11 fit more closely.

[0045] The installation auxiliary block 23 is located between the two adjustment components, and can play a limiting role so that the wedge-shaped wire core 2 is not easy to fall off during the replacement process.

[0046] like Figure 4-5 As shown: As a further improvement of the utility model, the wedge-shaped wire core 2 includes two half-cores 20 that are interlocked, wherein the wire entry hole 21 and the wire exit hole 22 are respectively located in a corresponding half-core 20, and the wedge-shaped wire core 2 is divided into two corresponding parts that are interlocked with each other. The wire 7 passes through the two half-cores 20 through the wire entry hole 21 and the wire exit hole 22 in turn, and then the two half-cores 20 are interlocked and loaded into the wedge-shaped accommodating cavity 100, which can reduce the difficulty of installation.

[0047] In the present application, the utility model can adjust the position of the wedge-shaped wire core and the entire wire clamp shell by setting a sliding groove and installing an auxiliary block, and at the same time use the adjustment component to tighten the left half and the right half to adjust the tightness between the wedge-shaped wire core and the wire clamp shell; by designing a split structure, the split structure simplifies the manufacturing method of the main structure, so that it can be produced and processed by a forging process to produce a detachable card connection method, which is not only conducive to the entire device being split into multiple small parts for carrying, but also allows the wire clamp equipment and wires to be quickly replaced; the split structure is very convenient and easy to construct and install. During maintenance, only the worn parts need to be replaced, without having to replace the entire set of wire clamp equipment, which reduces the difficulty of maintenance and is very practical.
