Description

Technical Field

[0001] This utility model relates to the field of power transmission line technology, specifically to a pole guy wire clamp assembly. Background Technology

[0002] Pole guy wires are an important component of transmission lines. The torque generated by the guy wires is used to balance the unbalanced torque borne by the tower, increasing the tower's stability. Typically, poles bearing significant fixed unbalanced loads, such as terminal poles, angle poles, and crossing poles, should be equipped with guy wires. Guy wires should also be installed to prevent damage from strong wind loads, or in areas with soft soil, to further increase pole stability.

[0003] From top to bottom, the guy wires of power distribution line towers generally consist of components such as clamps, extension rings, wedge clamps, wire ropes, UT clamps, guy bars, and ground anchors. The wedge clamp, commonly known as the upper clamp, is fixed to the upper end of the wire rope by wedges and connects to the extension ring; common models are the NX series. The UT clamp, commonly known as the lower clamp or bottom clamp, connects the wire rope to the guy bar and adjusts the tension of the guy wire; common models are the NUT series. To ensure reliable connection, both wedge clamps and UT clamps are usually made robust and sturdy, resulting in a relatively heavy clamp assembly and higher cost. Furthermore, wedge clamps rely on manual hammering to tighten the wire rope, while UT clamps require repeated adjustment of bolt tightness, making installation time-consuming and labor-intensive.

[0004] Therefore, there is an urgent need for a low-cost manifold clamp assembly to replace the existing wedge clamps and UT clamps, so as to simultaneously improve construction efficiency, reliability and economy. Utility Model Content

[0005] To simplify the structure and reduce production costs, this utility model provides a pole guy wire clamp assembly.

[0006] The technical solution adopted by this utility model is as follows: a pole guy wire clamp assembly, comprising: a first half tube and a second half tube arranged in pairs to form a clamping space for the wire rope; a wire rope clamp, clamped on the outer wall of the first half tube and the second half tube for fixing the wire rope; and a connector, welded to the first half tube and the second half tube for connecting with a clamping bolt or a guy wire rod.

[0007] Preferably, the connecting members are a long strip-shaped first connecting plate and a second connecting plate, which are respectively welded axially to the outer pipe wall at the same end of the first half-pipe and the second half-pipe. The upper ends of the first connecting plate and the second connecting plate are respectively provided with concentric first connecting holes and second connecting holes. The first half-pipe, the first connecting plate, the second half-pipe, the second connecting plate and the wire rope clamp together form an upper handle for connecting the clamp and the wire rope.

[0008] Preferably, the connector is a connecting ring, which has an annular segment and two straight segments extending outward from the end, with a gap between the two straight segments, and is respectively welded to the outer wall of the first half-pipe and the second half-pipe at the same end; the first half-pipe, the second half-pipe, the connecting ring and the wire rope clamp together form a lower handle for connecting the wire rope and the pull bar.

[0009] Preferably, it also includes a U-bolt and a third connecting plate, the third connecting plate having two third connecting holes corresponding to the U-bolt; the U-bolt and the third connecting plate together form a transition piece for connecting the lower handle and the pull bar.

[0010] Preferably, the lengths of the first half-tube and the second half-tube are 10 to 20 times their diameters.

[0011] Preferably, there are 2 to 4 wire rope clamps.

[0012] Preferably, the first half-tube and the second half-tube are cut from steel pipes or pressed from sheet metal.

[0013] This utility model has the following beneficial effects:

[0014] 1. Lightweight and cost optimization: The wire clamp is composed of a first half tube and a second half tube, replacing the traditional bulky wedge-shaped wire clamp and UT-type wire clamp. The structure is simplified and the material consumption is low. The half tube can be formed by cutting steel pipe or pressing sheet metal. Compared with castings, it is easier to process and significantly reduces manufacturing costs.

[0015] 2. Improved installation efficiency: The wire rope is directly locked to the outer wall of the half-pipe by wire rope clamps, eliminating the need for hammering wedges as required by traditional wedge clamps and the repeated bolt adjustment steps of UT clamps, thus reducing installation time;

[0016] 3. Connection reliability: The connector is directly welded to the outer wall of the half-pipe, and the force transmission path is clear, avoiding the failure risk of traditional wire clamps due to wedge loosening or thread stripping. The half-pipe length is designed to be 10 to 20 times the diameter, providing sufficient wrapping area. With 2 to 4 wire rope clamps for multi-point locking, it effectively prevents wire rope slippage. Attached Figure Description

[0033] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0034] In the embodiments, such as Figures 1-4 The image shows a guy wire clamp assembly for utility poles, comprising: a first half-tube 1 and a second half-tube 2 arranged in pairs to form a clamping space for a wire rope 3; a wire rope clamp 4 clamping the outer walls of the first half-tube 1 and the second half-tube 2 for fixing the wire rope 3; and a connector welded to the first half-tube 1 and the second half-tube 2 for connecting with a clamping bolt or a guy rod. This embodiment achieves rapid fixing of the wire rope 3 by using the paired first half-tube 1 and second half-tube 2 to form a clamping space for the wire rope 3, and by using the wire rope clamp 4 to lock the outer walls of the half-tubes. Compared with cast parts such as wedge clamps and UT clamps, the structure is simplified and material consumption is low, significantly reducing manufacturing costs. Furthermore, the connector is directly welded to the half-tubes, ensuring a clear force transmission path and reliable connection.

[0035] In the embodiments, such as Figure 1 , Figure 2As shown, the connecting parts are a long strip-shaped first connecting plate 5 and a second connecting plate 6, which are respectively welded axially to the outer wall of the same end of the first half-pipe 1 and the second half-pipe 2. The upper ends of the first connecting plate 5 and the second connecting plate 6 are respectively provided with concentric first connecting holes 5.1 and second connecting holes 6.1. The first half-pipe 1, the first connecting plate 5, the second half-pipe 2, the second connecting plate 6, and the wire rope clamp 4 together form the upper handle A, which is used to connect the clamp and the wire rope 3. The first connecting hole 5.1 and the second connecting hole 6.1 of the upper handle A are coaxially designed, and the clamp bolt can be directly inserted to complete the connection, eliminating the need for the extension ring required in the traditional guy wire structure and further reducing costs.

[0036] In the embodiments, such as Figure 1 , Figure 3 As shown, the connector is a connecting ring 7, which has an annular segment 7.1 and two straight segments 7.2 extending outward from the end. There is a gap between the two straight segments 7.2, and they are welded to the outer wall of the same end of the first half-pipe 1 and the second half-pipe 2, respectively. The first half-pipe 1, the second half-pipe 2, the connecting ring 7, and the wire rope clamp 4 together form the lower handle B, used to connect the wire rope 3 and the pull rod. The annular segment 7.1 of the lower handle B can directly hook the pull rod, replacing the wire rope 3 connection function of the UT-type clamp, and the tensile strength of the annular segment 7.1 is guaranteed.

[0037] In the embodiments, such as Figure 1 , Figure 4 As shown, it also includes a U-bolt 8 and a third connecting plate 9. The third connecting plate 9 has two third connecting holes 9.1 corresponding to the U-bolt 8. The U-bolt 8 and the third connecting plate 9 together form a transition piece C, used to connect the lower handle piece B and the pull rod. The transition piece C can be adapted to pull rods of different diameters through the U-bolt 8, and the U-bolt 8 also realizes the length adjustment function of the UT-type wire clamp. The third connecting plate 9 is machined from sheet metal, resulting in low production cost.

[0038] In the embodiments, such as Figures 1-3 As shown, the lengths of the first half-pipe 1 and the second half-pipe 2 are 10 to 20 times their diameters. Two to four wire rope clamps 4 are installed, with their clamping angles staggered. The first half-pipe 1 and the second half-pipe 2 ensure a sufficiently large wrapping area for the wire rope 3, providing strong anti-slip force and eliminating the risk of rope pull-out. The two to four wire rope clamps 4 create a multi-point pressure distribution, balancing the gripping force of the half-pipes on the wire rope 3 through symmetrically distributed pressure points. The double-clamp scheme meets conventional loads, while the four-clamp scheme can withstand extreme wind loads.

[0039] In this embodiment, the first half-tube 1 and the second half-tube 2 are cut from steel pipes or pressed from sheet metal. After the first half-tube 1 and the second half-tube 2 are cut from steel pipes or pressed from sheet metal, they are then welded to the connectors. This results in high material utilization and processing efficiency far exceeding that of traditional cast wire clamps, significantly reducing the cost per unit.

[0040] Obviously, the above embodiments of this utility model are merely examples for illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Other obvious variations or modifications derived from the essential spirit of the present utility model still fall within the protection scope of the present utility model.
