Abstract

The utility model relates to the technical field of power transmission lines, in particular to an armour rod-preformed bell-jar-type vibration-proof hammer metalware device. The armour rod-preformed bell-jar-type vibration-proof hammer metalware device is fixed on a conductive wire and comprises a hammer head, steel sleeves, a steel strand, a wire clamp, a preformed armour rod and a steel ball, wherein a circular arc-shaped hook is arranged at the upper end of the wire clamp; a circular arc-shaped through hole is formed at the lower end of the wire clamp; the conductive wire is arranged inside the circular arc-shaped hook; the steel strand penetrates through the circular arc-shaped through hole; the steel sleeves are arranged at the two ends of the steel strand respectively; the hammer head has a bell-jar shape; a first cavity and a second cavity are formed inside the hammer head and are communicated through a passage; the steel ball is arranged inside the first cavity; the steel sleeves are arranged inside the passage; the steel sleeves are ejected open by the steel ball and reversely riveted and fixed on the hammer head; and the preformed armour rod is wound at the upper parts of the conductive wire and the hammer head. The armour rod-preformed bell-jar-type vibration-proof hammer metalware device is simple in structure, good in anti-sliding effect and energy-saving.

Description

A kind of preformed armor rods bell-jar damper hardware tool device

Technical field

The utility model relates to the transmission line technical field, specifically a kind of preformed armor rods bell-jar damper hardware tool device.

Background technology

After the aeolian vibration phenomenon is found; various types of stockbridge dampers just emerge in succession; the stockbridge damper type that adopt countries in the world is a lot; through constantly putting into practice and Operation trial; what vibration-isolating effect was bad has been eliminated gradually; and new version constantly occurs; find by long-term practice and research; exist long-time running shockproof hammer thread clip bolt looseness easily to cause slippage or the phenomenon that drops; tup be connected with steel strand wire because of Long-term Vibration easily come off or with the friction that bumps of tup cylinder limit, damage steel strand wire, make stockbridge damper impaired; affect the defectives such as vibration-isolating effect, do not have the guardwire effect.

The utility model content

The utility model provides a kind of simple in structure, good antiskid effect, energy-saving preformed armor rods bell-jar damper hardware tool device.

The utility model is achieved through the following technical solutions:

A kind of preformed armor rods bell-jar damper hardware tool device, be used for being fixed on wire, comprise tup, steel bushing, steel strand wire, wire clamp, preformed armor rods and steel ball, described wire clamp upper end is provided with the circular arc crotch, described wire clamp lower end is provided with manhole, described wire is located in the described circular arc crotch, described steel strand wire pass described manhole, described steel strand wire two ends respectively are provided with a steel bushing, described tup is bell-jar, be provided with the first cavity and the second cavity in the described tup, and be connected by passage, described steel ball is located in described the first cavity, and described steel bushing is located in the described passage, and back down the steel bushing anti-riveting by steel ball and press solidly on the described tup, described preformed armor rods is wound in described wire and tup top.

The outline of the circular arc crotch on described wire clamp top is provided with four projections, and described preformed armor rods comprises three, snaps in respectively in the depressed part between described per two projections.

The second cavity of described tup is horn-like.

Described channel cross-section is hexagon, and described steel bushing is located at the steel strand wire end and is pressed into hexagon.

The beneficial effect that the utility model brings is:

In the utility model, described preformed armor rods bell-jar damper hardware tool device comprises tup, steel bushing, steel strand wire, wire clamp, preformed armor rods and steel ball, it is the device that can suppress or reduce aeolian vibration, described steel bushing is located in the described passage, and back down the steel bushing anti-riveting by steel ball and press solidly on the described tup, reduced the operation of traditional approach fixed hammer two ends envelope tin, avoided long-time running to be corroded, the danger that the vibrationproof tup that the reasons such as cracking cause comes off, and make tup ball smooth surface, prevent that effectively corona from occurring, and energy-saving effect is remarkable, improves 8 ~ 15%; The outline of the circular arc crotch on described tup top is provided with four projections effectively fixing cord and wire clamp position; prevent slippage; avoid bolt fixing to the damage of wire and because bolt looseness causes the slippage of stockbridge damper even the danger that comes off; and dispersive stress reduces the stress in wire clamp exit; alleviated the fatigue of wire; well guardwire, and location and installation is convenient.
