Description

Technical Field

[0001] The utility model relates to the technical field of pre-twisted metal fittings, in particular to a pre-twisted combined wire-stayed metal fitting for a pole tower. Background Art

[0002] A tower is a structure used to support transmission lines in overhead transmission lines, while a pre-twisted fitting is a fitting that uses pre-formed spiral strips to wrap around conductors or ground wires to withstand mechanical or electrical loads.

[0003] In the prior art, pre-twisted hardware refers to hardware in which a pre-formed spiral strip is wound around a conductor or ground wire, and its main function is to disperse concentrated stress. Pre-twisted hardware is mainly used in combination with accessories such as U-shaped hanging rings and extension rings to improve the strength of the conductor or ground wire. However, during the installation process of existing pre-twisted hardware, when it is wound and installed on the conductor or ground wire, the pre-twisted hardware often cannot be fully expanded. This can easily lead to loose contact between the pre-twisted wire and the conductor or ground wire, resulting in insufficient protection strength. Therefore, we propose a pre-twisted combined wire tensioning hardware for pole towers. Utility Model Content

[0004] The purpose of the present utility model is to solve the shortcomings existing in the prior art. Pre-twisted hardware refers to hardware in which a pre-formed spiral strip is wound around a conductor or a ground wire, which mainly plays the role of dispersing concentrated stress. The pre-twisted hardware is mainly used in combination with accessories such as U-shaped hanging rings and extension rings to improve the strength of the conductor or the ground wire. However, during the installation process of the existing pre-twisted hardware, when it is wound and installed on the conductor or the ground wire, the pre-twisted hardware often cannot be fully expanded. This easily leads to loose contact between the pre-twisted wire and the conductor or the ground wire, thereby resulting in insufficient protection strength.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A pre-twisted combined wire tensioning hardware for a pole tower comprises a pre-twisted wire body, a conductor body is installed on the inner side of the pre-twisted wire body, an extension ring is clamped on the inner side of the left side of the pre-twisted wire body, an adjustment clamp is installed on the inner side of the extension ring near the center, and the pre-twisted wire body and the adjustment clamp are clamped, a rotation groove is correspondingly provided on the right side of the adjustment clamp, a first nut is symmetrically fixed to the right side of the extension ring, a first bolt is threadedly intersected on the inner side of the first nut, and the first bolt passes through the extension ring and is clamped in the rotation groove.

[0007] As a preferred solution of the present invention, a mounting hole is provided on the right side of the extension ring and extends through the inner side of the extension ring. An anti-wear sleeve is clamped on the inner side of the mounting hole, and the anti-wear sleeve is made of rubber material.

[0008] The technical effect of adopting the above further solution is that, through the provision of the anti-wear sleeve, the anti-wear sleeve can well protect the contact area between the wire body and the extension ring, thereby effectively preventing wear.

[0009] As a preferred solution of the present invention, a second bolt is installed from the bottom of the left side of the extension ring to the top, a second nut is installed at the top of the left side of the extension ring, and the second bolt and the second nut threads intersect.

[0010] The technical effect of adopting the above further solution is that the U-shaped clamping ring and the extension ring can be conveniently connected and combined together through the provision of the second bolt and the second nut.

[0011] As a preferred solution of the present invention, the bottom of the second nut and the top of the extension ring are clamped with the first washer, and the first washer is made of iron metal material.

[0012] The technical effect of adopting the above further solution is that the second nut and the second bolt can be prevented from loosening by providing the first washer.

[0013] As a preferred solution of the present invention, the inner side of the extension ring extends to the left side where a U-shaped hanging ring is clamped, and the back side of the left side of the U-shaped hanging ring passes through to the front side where a third bolt is fixed.

[0014] As a preferred solution of the present invention, a third nut is installed on the front side of the U-shaped hanging ring, and the third bolt intersects with the third nut thread.

[0015] As a preferred solution of the present invention, a second washer is clamped on the back of the third nut and on the front of the U-shaped hanging ring, and the second washer is made of iron metal.

[0016] As a preferred solution of the present invention, the wire body is clamped with the anti-wear sleeve, and the wire body passes through the anti-wear sleeve and extends out from the side of the extension ring.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] In the present invention, by adjusting the setting of the clamping ring, the adjusting clamping ring can be effectively clamped with the pre-twisted wire body, so that the pre-twisted wire body can be easily expanded by adjusting the position of the clamping ring. By setting the first bolt, the first bolt is adjusted to a depth of the first bolt penetrating into the extension ring through the intersection of threads in the first nut, so that the rotating groove on the adjusting clamping ring is squeezed by the first bolt, thereby driving the adjusting clamping ring to move inside the extension ring, so that the adjusting clamping ring can unfold the pre-twisted wire body so that it can fit tightly to the surface of the wire body, thereby providing strong protection.
