Abstract
The utility model relates to a shock-proof hammer, belonging to a device used for damping mechanical oscillation of lines on overhead transmission lines. The utility model is composed of a hammer body, a steel stranded connecting wire, and a wire clamp, wherein, the hammer body is an L-shaped entity structure, the non-connected end of the L-shaped entity structure forms a spherical shape; a pair of L-shaped entity hammer bodies are fixed at both ends of the steel stranded connecting wire, and the wire clamp connected with the middle part of the steel stranded connecting wire is made of non-magnetic materials. The utility model has the advantages of high antirust property, long service life, reasonable structure, extensive frequency response range, and energy saving.
Description
The utility model relates to the device of damping circuit mechanical oscillation on a kind of overhead transmission line.
The vibration absorber of overhead transmission line adopts the stockBridge stockbridge damper mostly at present.It is to be made of a pair of hollow cylindrical tup of a steel strand wire two end axles to horizontal fixed, and is that fulcrum hangs on the power transmission line with the mid point of steel strand wire.This stockbridge damper has the following disadvantages: 1. often gather foreign material, aqueous vapor etc. in the hollow tup, thereby tup and steel strand wire easy-to-rust, useful life is shorter; 2. the tup frequency scope of application of straight tubular construction is narrower; 3. the wire clamp that connects power transmission line is the ferrimagnet manufacturing, and energy consumption is bigger.
The purpose of this utility model provides a kind of rational in infrastructure, is difficult for corrosion, long service life, the overhead transmission line stockbridge damper that frequency response range is wider and energy-conservation.
The technical solution that realizes above-mentioned purpose is: hammer body is designed to L shaped entity structure, and its L shaped front of motor is spherical, and pair of L-shaped entity hammer body is fixed in the two ends of steel strand connecting line, makes with non-magnet-wire material with the wire clamp that steel strand connecting line middle part is connected.
Accompanying drawing 1 is the utility model general structure schematic diagram.
Accompanying drawing 2 is the end view of accompanying drawing 1.
The utility model is described in further detail below in conjunction with accompanying drawing.
Hammer body 1 is L shaped entity ironcasting, and the appearance hot galvanizing is with anticorrosion.A wherein straightway one end that constitutes two L shaped straightways is provided with the steel strand connecting line installing hole that parallels with another straightway, and the front of motor of another straightway is spherical, and L shaped two straightways are 95 ° of angles.L shaped hammer body 1 is fixed in the two ends of steel strand connecting line 2, and lays respectively at the both sides of steel strand connecting line 2, make its L shaped plane and steel strand connecting line axis be downward 45 ° of angles.The suspension clamp that is connected in steel strand connecting line 2 middle parts is made of body 4, pressing plate 5 and fastening bolt 6.Body 4 tops are provided with bent hook-type pressuring line groove, and the middle part offers bolt hole, and the bottom is provided with the cross-drilled hole that connects steel strand connecting line 2.Pressing plate 5 is provided with the pressuring line groove of the fixedly connected power transmission line 3 that matches with the bent hook-type pressuring line groove of body, is provided with bolt hole simultaneously.Present embodiment is made the nonmagnetic substance aluminium alloy material of wire clamp, and it is corrosion resistant both, and intensity is good, does not have magnetic hysteresis loss again, thereby reduces energy consumption.
Evidence, the utility model resistant tarnishing is strong, and long service life is rational in infrastructure, and frequency response range is wider, and energy savings.
