Description

Technical Field

[0001] This utility model relates to the field of fixing fixture technology, specifically a double-fastening fixing fixture for a straight pole of an overhead power line. Background Technology

[0002] Straight poles for overhead power lines are the most common and basic type of poles in power transmission and distribution lines. Straight poles are used to support conductors and ground wires and ensure the safe distance between the line and the ground under various weather conditions. They mainly bear the vertical load (weight) of conductors, insulator strings and hardware and the horizontal wind load, but do not bear significant tension along the line direction. Therefore, the fixing clamps used with the straight poles of overhead power lines are a set of components that fix the conductors to the insulator strings of the straight poles, collectively referred to as suspension clamps. They firmly hold the conductors and suspend them below the insulator strings, transferring the load (weight, wind pressure, ice weight) of the conductors to the poles. However, the existing fixing clamps still have the following drawbacks: Since the current fixing clamps only fix the conductors to the insulator strings of the straight pole with a single set of clamps, the single set of clamps makes them prone to accidental failure due to lightning strikes, material fatigue, construction defects, etc., which can lead to the conductors falling and cause major power outages. Therefore, the practicality and strength of the current fixing clamps are reduced. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a double-fastening clamp for straight poles of overhead power lines.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a double-fastening and fixing clamp for a straight pole of an overhead power line, the structure of which includes: a fixing groove, a fixing seat, a clamp body, a slot, and a fastening tube. The fixing groove and the fixing seat are an integrated structure and the fixing seat is perpendicular to the clamp body. The clamp body has a slot on its side for connecting and fixing the fastening tube.

[0005] Furthermore, the fastening tube is provided with a threaded layer, which is an integral structure with the edge of the tube body. The tube body has a placement groove inside and a locking groove on the outer edge.

[0006] Furthermore, a limiting ring is provided inside the tube body. The inner wall of the limiting ring is provided with an insulating ring and a fastening gasket. A locking bolt is connected to the center of the upper end of the fastening gasket to pass through the locking groove.

[0007] Furthermore, the fixing groove is circular in shape and opened in the lateral direction. The fixing seat and the clamp body are integrated. The slot of the clamp body is circular in shape and matches the shape of the fastening tube. The clamp body and the fixing seat are provided in two sets and the fastening tube is laterally defined.

[0008] Furthermore, the tube body has multiple threaded layers on its edge that are threadedly connected to the fixture body. The shape of the tube body's placement groove matches the shape of the slot, and their centers overlap. The locking groove has an internal thread.

[0009] Furthermore, the surface of the insulating ring inside the limiting ring is provided with anti-slip texture and an arc-shaped fastening washer is added. The locking pin matched with the fastening washer is compatible with the internal thread of the locking groove.

[0010] Furthermore, the two sets of fixing seats and fixing slots of the two sets of clamp bodies are connected to the two hanging points on the crossarm of the tower. Then, the conductor is put into the two sets of clamp bodies through a fastening tube. The tube body is then fixedly connected to the two sets of clamp bodies through the threaded layer. Finally, the conductor is fixed by the insulating ring and fastening gasket inside the tube body. Beneficial effects

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model is based on two sets of fixed seats and two sets of clamp bodies. The two sets of fixed seats are installed on two hanging points on the crossarm of the tower by fixing grooves. Then, two independent strings of suspension insulators are suspended. Each string of insulators is connected to a complete clamp body. The same wire is clamped by the same fastening tube, so as to achieve a double fastening and fixing effect. Therefore, it can avoid the large-scale power outage caused by the wire falling when one set fails. It can improve reliability, increase mechanical strength, facilitate maintenance and replacement, and improve the overall practicality of the fixing clamp.

[0012] 2. This utility model, through the improvement of the fastening tube, allows for a stable threaded connection between the tube's threaded layer and the two sets of clamp bodies, facilitating easy assembly and disassembly. Furthermore, the locking groove on the edge allows the locking bolt to pass through and control the internal fastening gasket. Thus, after the wire enters the limiting ring and contacts the insulating ring, it can be pressed by the fastening gasket, improving the fixing strength of the wire. At the same time, the anti-slip texture of the insulating ring increases the friction with the wire, ensuring that the wire can be positioned in a stable state. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example

[0019] like Figures 1-3 As shown, this utility model provides a double-fastening and fixing clamp for straight poles of overhead power lines. Its structure includes: a fixing groove 1, a fixing seat 2, a clamp body 3, a slot 4, and a fastening tube 5. The fixing groove 1 and the fixing seat 2 are an integrated structure, and the fixing seat 2 and the clamp body 3 are perpendicular to each other. The clamp body 3 has a slot 4 on its side for connecting and fixing with the fastening tube 5.

[0020] The fastening tube 5 is provided with a threaded layer 51, which is an integral structure with the edge of the tube body 52. ​​The tube body 52 has a placement groove 53 inside and a locking groove 54 on the outer edge.

[0021] The tube body 52 is also provided with a limiting ring 521 inside. The inner wall of the limiting ring 521 is provided with an insulating ring 522 and a fastening gasket 523. A locking bolt 524 is connected to the center of the upper end of the fastening gasket 523 to pass through the locking groove 54.

[0022] The fixing groove 1 is circular and open in the lateral direction. The fixing seat 2 and the clamp body 3 are integrated. The slot 4 of the clamp body 3 is circular and matches the shape of the fastening tube 5. The clamp body 3 and the fixing seat 2 are provided in two sets and the fastening tube 5 is laterally limited.

[0023] The tube body 52 has multiple threaded layers 51 on its edge that are threaded to the fixture body 3. The shape of the placement groove 53 of the tube body 52 matches the shape of the slot 4 and their centers overlap. The locking groove 54 has an internal thread.

[0024] The insulating ring 522 inside the limiting ring 521 has anti-slip texture on its surface and an arc-shaped fastening washer 523 is added thereto. The locking bolt 524 matched with the fastening washer 523 is matched with the internal thread of the locking groove 54.

[0025] The two sets of fixing seats 2 and fixing grooves 1 of the two sets of clamp bodies 3 are connected to the two hanging points on the crossarm of the tower. Then, the wire is put into the two sets of clamp bodies 3 through a fastening tube 5. Then, the tube body 52 of the fastening tube 5 is fixedly connected to the two sets of clamp bodies 3 through the thread layer 51. Then, the wire is fixed by the insulating ring 522 and fastening gasket 523 inside the tube body 52.

[0026] The working principle of this utility model is explained below: The double-fastening fixing clamp can adopt two independent clamp bodies 3, two sets of fixing seats 2, and fixing grooves 1. The fixing grooves 1 of the fixing seats 2 are used to position the clamps at two hanging points on the crossarm of the tower, respectively suspended from two independent strings of vertical insulators. Each string of insulators has a complete clamp body 3 below it. The two clamp bodies 3 can then be used to fix a fastening sleeve 5 through slots 4, allowing the same conductor to be positioned through the fastening sleeve 5. Therefore, a double-fastening effect is achieved. When one set of clamp bodies 3 fails, the other set of clamp bodies 3 can bear the entire load alone, avoiding the large-scale power outage caused by the conductor falling after the failure of a single clamp body 3. Therefore, it achieves the double-fastening effect and improves the practicality of the fastening clamp. Furthermore, the tube body 52 of the fastening tube 5 can be threaded with the clamp body 3 through the threaded layer 51. The connection is fixed to facilitate disassembly and assembly. The self-tightening function of the thread improves the overall stability of the origin positioning of the component. Then, the placement groove 53 of the tube body 52 can be combined with the slot 4 to allow the wire to be inserted and placed, achieving the positioning effect. Subsequently, based on the locking groove 54 on the edge of the tube body 52, the limiting ring 521 inside the tube body 52 can determine the position of the insulating ring 522. After the wire is inserted, the insulating ring 522 can increase the friction with the edge of the wire through the anti-slip texture, thus improving the stability of the origin positioning of the wire. Furthermore, the fastening pad 523 can directly fasten and press the edge of the wire by locking the locking bolt 524. The locking bolt 524 can be rotated and fixed through the internal thread of the locking groove 54, thus further improving the fixing effect of the wire and ensuring that the wire is fixed in a stable and tight state in the fixing fixture. Therefore, it can further improve the stability of the double fastening fixing fixture.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
