Long-span two-body damper

Abstract

The invention relates to a long-span two-body damper, in particular to a long-span special two-body damper which belongs to a protection tool for absorbing the vibration energy of an overhead cable and is especially suitable for complex transmission lines with long span and frequent line vibration. The long-span two-body damper comprises a cable clamp I, a cable clamp II, a pre-twisted wire, a steel strand, a middle hammer, a big hammer I and a big hammer II; a hook-shaped sleeve is respectively arranged at the upper part of the cable clamp I and the cable clamp II, a neck is respectively arranged at the head part of the cable clamp I and the cable clamp II, a through hole is respectively arranged at the lower part of the cable clamp I and the cable clamp II, the hook-shaped sleeves arranged at the upper parts of the cable clamp I and the cable clamp II are sleeved on a cable, the pre-twisted wire passes through the necks at the upper parts of the cable clamp I and the cable clamp II and are fixedly connected with the cable, and the steel strand are arranged in the through holes at the lower parts of the cable clamp I and the cable clamp II in a penetrating way and pressed and fixed; the steel stand passes through the through holes arranged at the lower parts of the cable clamp I and the cable clamp II, the middle part of the steel strand passes through the middle hammer, two ends of the steel strand respectively extend into the bag hammer I and the big hammer II, and the three hammers are connected in series by the adhesion of adhesive.

Description

technical field [0001] The invention relates to a double-body anti-vibration hammer for large spans, which relates to a special double-body anti-vibration hammer for large spans. Background technique [0002] The anti-vibration of transmission lines has always been weak in my country, and there is no special anti-vibration hammer designed to effectively solve the hazards of line vibration for large spans in China. At present, domestic large-span transmission lines generally use ordinary anti-vibration hammers, which are installed in series; in special cases, damping lines are used for joint anti-vibration installation. Ordinary anti-vibration hammer has a narrow frequency of excited vibration, low energy consumption and can not really reflect the anti-vibration effect of the line, which greatly shortens the operating life of the line; Slippage occurs in the pipeline, which seriously affects the normal operation and service life cycle of the line. Thirdly, it is connected b...

Problems solved by technology

Ordinary anti-vibration hammer has a narrow frequency of excited vibration, low energy consumption and can not really reflect the anti-vibration effect of the line, which greatly shortens the operating life of the line; Slip phenomenon occurs in the middle, which seriously affects the normal operation and service life cycle of the line

Thirdly, it is connected by bolts, which is inconvenient for installation and construction for high-altitude operations; the vibration frequency range of ordinary anti-vibration hammers is limited, and the installation location is very particular
