Abstract

The invention discloses an anti-wire falling damping spring damper, which comprises a damper wire clamp and a damper, wherein the damper is connected with the damper wire clamp and is fixedly arrangedon the wire through the damper wire clamp; the damper comprises a cylinder body and a balance weight plate arranged in the cylinder body; the damper wire clamp is connected with one end of a damper connecting rod; one end of the damper connecting rod extends into the cylinder body and is connected with a counterweight plate through a damping spring; a through hole for the preformed armor rod to penetrate through is formed in the damper wire clamp; the two ends of the preformed armor rod are spirally arranged on the wires on the two sides of the damper wire clamp in a sleeving mode; the two ends of the preformed armor rod are fixed through connecting mechanism wire clamps; and the two connecting mechanism wire clamps are hinged through a connecting mechanism. The damping spring is adoptedto assist in consuming vibration energy, vibration reduction and buffering are provided through the preformed armor rods, cable abrasion at the damper wire clamp can be reduced, meanwhile, broken wirebackup protection is provided at the damper wire clamp, and support is provided for a broken wire cable.

Description

Technical field: [0001] The invention relates to the technical field of power transmission lines, in particular to a damping spring anti-vibration hammer for preventing line drop. Background technique: [0002] At present, anti-vibration hammers are widely used in China as a control measure for transmission line vibration. The principle of anti-vibration hammer is to absorb and convert the vibration energy into heat energy or sound energy and dissipate it, thereby increasing the energy consumption of the vibration system, so that the wire can achieve energy balance at a small amplitude. When the line vibrates, the collet of the anti-vibration hammer also moves up and down with the wire, and the heavy hammer has a large inertia and cannot move synchronously with the collet, so that the steel strands of the anti-vibration hammer are constantly bent up and down, and the strands are constantly rubbed. Thus dissipating most of the vibration energy on the transmission line. [0...
