Abstract

This invention discloses a wear-resistant hardware for split conductor damping wires, comprising a spring damper, a through bolt clamp, and a damping wire clamp. The through bolt clamp, which holds the through bolt, is fixedly mounted on the fixed rod of the spring damper. The damping wire clamp, which holds the damping wire, is fixedly mounted on the movable rod of the spring damper. The advantages are: compared with existing technologies, this invention effectively weakens the vibration energy of the damping wire using vibration reduction technology, creating a gap between the damping wire and the suspension clamp to maintain a safe distance and prevent friction between the damping wire and the suspension clamp. This prevents damage to the damping wire, extends its service life, and improves its utilization rate, making it worthy of widespread application.

Description

Technical fields:

[0001] This invention relates to a high-voltage power transmission fitting, and more particularly to a split conductor damping wire anti-wear fitting. Background technology:

[0002] In overhead transmission lines, due to the height of the towers and the large spans, the conductors vibrate when subjected to wind forces. The working conditions at the conductor suspension points are most unfavorable during this vibration. Repeated vibrations can cause fatigue damage to the conductors due to periodic bending. To reduce and mitigate conductor vibration, transmission lines are often equipped with vibration dampers and damping wires to prevent line wear, strand breakage, and fracture caused by wind, ensuring the safe and stable operation of the transmission lines.

[0003] However, the damping wire on the split conductor passes through the fixing hardware of the fixed suspension clamp. When the damping wire is vibrated by wind, it will rub against the fixing hardware of the fixed suspension clamp on both sides of the damping wire, which will cause the damping wire to wear, break strands and break, affecting the safe and stable operation of the transmission line. Summary of the Invention:

[0004] The purpose of this invention is to provide a wear-resistant hardware for split conductor damping wires that prevents wear caused by friction between the damping wire and the suspension wire clamp.

[0005] The present invention is implemented by the following technical solution: a split conductor damping wire anti-wear hardware, which includes a spring damper, a through bolt clamp, and a damping wire clamp. The through bolt clamp, which is clamped on the through bolt, is fixed on the fixed rod of the spring damper, and the damping wire clamp, which is clamped on the damping wire, is fixed on the movable rod of the spring damper.

[0006] Preferably, the spring damper includes a sleeve, a fixed rod, a movable rod, and a tension spring; elongated holes are symmetrically formed on the sleeve wall along the length of the sleeve; the fixed rod is inserted into one end of the sleeve, and the movable rod is movably inserted into the other end of the sleeve; the tension spring is disposed inside the sleeve; one end of the tension spring is fixedly connected to the fixed rod by a bolt passing through the sleeve wall; the other end of the tension spring is fixedly connected to the movable rod by bolts placed in the symmetrical elongated holes on the sleeve wall;

[0007] Preferably, the through bolt clamp is a split-type clamp.

[0008] Preferably, the damping wire clamp is a rotary tube clamp, which includes a ball head, a ball socket, a fixed buckle, and a movable buckle; the ball head is movably placed in the ball socket, and the ball head is fixedly connected to the movable rod; the fixed buckle is fixedly provided on the ball socket, and the movable buckle is movably provided on the ball socket.

[0009] Advantages of this invention: Compared with the prior art, this invention utilizes vibration reduction technology to effectively weaken the vibration energy of the damping wire, creating a gap between the damping wire and the suspension clamp to maintain a safe distance and prevent friction between the damping wire and the suspension clamp. This helps prevent damage to the damping wire, extends its service life, and improves its utilization rate, making it worthy of widespread application. Attached image description:

[0012] Figure 3 This is a schematic diagram illustrating the use of the present invention. Detailed implementation method:

[0013] Example: Figure 1 and Figure 2 As shown, the anti-wear hardware for split conductor damping wire includes a spring damper 1, a through bolt clamp 2, and a damping wire clamp 3. The spring damper 1 includes a sleeve 11, a fixed rod 12, a movable rod 13, and a tension spring 14. Elongated holes 15 are symmetrically formed along the length of the sleeve 11 on its wall. A fixed rod 12 is inserted into one end of the sleeve 11, and a movable rod 13 is movably inserted into the other end. A tension spring 14 is located inside the sleeve 11. One end of the tension spring 14 is fixedly connected to the fixed rod 12 via a bolt passing through the wall of the sleeve 11. The other end of the tension spring 14 is connected to the fixed rod 12 via a bolt placed in a long... The bolt in the slot 15 is fixedly connected to the movable rod 13; a through bolt clamp 2 is fixedly provided on the fixed rod 12 of the spring damper 1, which clamps the through bolt 4. The through bolt clamp 2 is a half-type clamp; a damping wire clamp 3 is fixedly provided on the movable rod 13 of the spring damper, which clamps the damping wire 7; the damping wire clamp 3 is a rotating clamp, which includes a ball head 31, a ball socket 32, a fixed buckle 33 and a movable buckle 34; the ball head 31 is movably placed in the ball socket 32, and the ball head 31 is fixedly connected to the movable rod 13; a fixed buckle 33 is fixedly provided on the ball socket 32, and a movable buckle 34 is movably provided on the ball socket 32.

[0014] Instructions for use: (e.g.) Figure 3As shown, the anti-wear hardware for split conductor damping wire disclosed in this invention is fixed to the through bolt 4 of the fixing hardware 6 passing through the suspension clamp 5 by the through bolt clamp 2; the spring damper 1 on the through bolt clamp 2 is set vertically upwards, and the damping wire clamp 3 is clamped on the damping wire 7 passing through the fixing hardware 6 of the suspension clamp 5. When the damping wire 7 is vibrated by wind, under the action of the spring damper 1, the damping wire 7 will not contact the fixing hardware 6 of the suspension clamp 5. The rotating pipe clamp type damping wire clamp 3 ensures that when the damping wire 7 is vibrated by wind, the damping wire clamp 3 will not generate radial shear force with the damping wire 7, causing wear of the damping wire 7, extending the service life of the damping wire, and improving the utilization rate of the damping wire.
