Description

Technical Field

[0001] This invention belongs to the technical field of power transmission line construction equipment, specifically relating to a high-altitude temporary anchor anti-bending wire clamp for power transmission conductors. Background Technology

[0002] Wire clamps are devices used by power supply departments to lay out, tighten, and anchor conductors to the ground or tension strings, serving as temporary anchors and are essential construction tools in the tensioning of transmission lines.

[0003] At present, with the construction of ultra-high voltage power transmission lines and the rapid development of new materials, the large-scale application of carbon fiber composite core conductors has put forward higher requirements for their overhead line construction technology. Especially at the ends of the tension section, after the conductors at both ends are laid out, it is necessary to temporarily anchor the conductors to the crossarms of the tension tower before the conductors are cut, crimped, and tightened. Due to its advantages such as high tensile strength, small sag, corrosion resistance, light weight, and strong conductivity, carbon fiber composite core conductors have been widely used in overhead transmission line projects. However, carbon fiber conductors have poor bending resistance. After tension laying, during the high-altitude temporary anchoring and tightening process, when using conventional wire clamps to temporarily anchor the conductors at high altitude, the conductors at the rear outlet of the wire clamps may be bent at a large angle, which may damage the carbon fiber core rod or even cause the conductors to break. This poses a great safety hazard to the overhead line construction of carbon fiber composite core conductors. Summary of the Invention

[0004] In order to solve the technical problem in the prior art that the conductor is damaged or broken due to large-angle hard bending during the process of high-altitude anchoring and tightening of the conductor, the present invention provides a high-altitude anchoring anti-bending clamp for transmission conductors, including: a parallel movable clamp, an anti-bending lifting hook and a connector connected to each other.

It is an indispensable construction tool in the tension construction of power transmission lines.

[0046] The anti-bend wire clamp is installed on the conductor between poles and towers, and includes: a parallel movable wire clamp 1, an anti-bend wire lifting hook 2, and a connector connected to each other;

[0047] The anti-bend cable clamp is suspended on the tower via the connector;

[0048] The parallel-moving wire clamp 1 is a hollow structure with a certain length;

[0049] like Figure 5 As shown in the figure, a is a schematic diagram of the bottom diameter of the anti-bend lifting hook groove, and b is a schematic diagram of the depth of the anti-bend lifting hook groove; furthermore, the anti-bend lifting hook 2 is an arc-shaped structure with a groove, and the center of the arc and the connecting piece are located on both sides of the anti-bend lifting hook 2;

[0050] The power transmission conductor passes through the hollow structure and enters the arc-shaped structure of the anti-bend lifting hook 2;

[0051] The anti-bending wire clamp provided by this invention effectively reduces the hard bending angle of the wire at the outlet of the wire clamp, preventing the wire from being damaged or broken due to excessive bending.

[0052] The parallel moving wire clamp 1 includes a clamping structure, a folding structure, a parallel pull plate mechanism 101, and a fastening connection part;

[0056] The clamping structure is connected to the other end of the parallel pull plate mechanism 101; the clamping structure is also connected to the other end of the folding structure.

[0057] The clamping structure has two working states. When the folding structure in the first connecting hole is close to the clamping structure, the clamping structure is closed by the action of the other end of the folding structure.

[0066] That is, the pulling force is transmitted to the body of the wire clamp through the parallel pulling plate mechanism 101. The body is both a mechanical structure and a force amplification mechanism. Therefore, the pulling force is not only converted into the positive pressure of the clamp, but also amplified in magnitude to ensure that the wire is stable and does not come off when clamped.

[0067] The arc-shaped structure has an arc surface, which faces away from the connecting pull ring 3; and the angle between the two ends of the arc surface and the center of the circle is any angle between 20° and 30°.
