Description

Technical Field

[0001] The utility model relates to the field of tension wire clamp devices, in particular to an aluminum alloy bolt type tension wire clamp. Background Art

[0002] Strain clamps are used to fix conductors to withstand the conductor tension and hang the conductors on the tension string group or pole tower. Strain clamps are used for cornering, splicing, and terminal connection. Spiral aluminum-clad steel wire has extremely strong tensile strength and no concentrated stress, which protects the optical cable and assists in vibration reduction. The complete set of optical cable tension fittings includes: tension pre-twisted wire and matching connection fittings. The clamp grip is not less than 95% of the rated tensile strength of the optical cable. It is easy and quick to install, reducing construction costs. It is suitable for ADSS optical cable lines with a span of ≤100 meters and a line angle of <25°.

[0003] However, the existing tension wire rack is inconvenient to install and has low installation efficiency. The pressure plate, bolts and body are all independently arranged, and the structure is scattered, which poses a safety hazard to the installation of high-altitude lines. In addition, the pressure plate of the existing bolt-type tension wire clamp is long and strip-shaped, and both ends are fixed by U-bolts. This connection method will cause the other end of the pressure plate to tilt up when the U-bolt at one end is tightened, resulting in an unstable clamping line or causing the originally clamped pressure plate to move.

[0004] In order to overcome the shortcomings of the prior art, the utility model provides an aluminum alloy bolt type tension clamp, which first fixes the positioning component to the clamp body and then performs auxiliary connection through a clamp block.

[0006] As a preferred technical solution of the utility model, the top end of the clamp block is provided with an arc-shaped groove which fits with the bottom end of the wire clamp body.

[0007] As a preferred technical solution of the utility model, a plurality of positioning grooves are equidistantly provided on the top of the wire clamp body, and the positioning grooves are all threaded hole structures, and the connecting bolts penetrate the clamp frame and the positioning grooves for fixed connection.

[0010] As a preferred technical solution of the present invention, the inner diameter of the clamping frame is matched with the outer diameter of the wire clamp body.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0012] In the present device, through the U-bolt-positioning component structure, the user can determine the number and position of the positioning components on the wire clamp body according to the length and width of the cable.
