Abstract
The utility model discloses a self -adaptation formula is two hangs pairs cluster that dangles, link plate on connecting two on the shaft tower cross arm, respectively with two ball -eye that go up link plate swing joint, connect dish -type or composite insulator at two ball -eye lower extremes respectively, connect the socket -clevis eye at two insulator lower extremes respectively, still include the yoke plate, the socket -clevis eye lower extreme is connected on the yoke plate, be equipped with a curved rack on the yoke plate, this arc rack's inboard is equipped with dentate structure, be equipped with on the yoke plate at least two with this radial gear meshing's lower gear, the gear is through selling axle or bolted connection on the yoke plate down, both ends at arc rack are connected with suspension clamp respectively, the last line clamp that is connected with of suspension clamp. The utility model aims at providing a self -adaptation formula is two hangs pairs cluster that dangles, string insulation of dangling is fixed, favourable insulation protection, according to both sides conductor tensile force, utilize gear structure automatically regulated fastener height, ensure that both ends fastener atress is evenly balanced.
Description
Technical field
This utility model belongs to transmission line of electricity field, more particularly to a kind of double extension duplex suspension strings of self-adapting type.
Background technology
During Transmission Line Design, Jing often adopts duplex suspension string in important Crossover phase, but when the duplex of independent hanging point
In the shaft tower of continuous up-and downhill, often two suspension string unbalance stress of outlet, or even a string of stress and a string are lax for string outlet
Situation.Generally employing mode has the following two kinds：（1）Using duplex list hanging point mode, reversed using connection version, two string hanging point of adjustment
Highly, two string force balances are automatically achieved, is reduced the powered point in insulation lower section and the spacing of insulation top earth point, is unfavorable for insulation
Protection；（2）Suspension string is hung using duplex is double, two strings is analyzed using stretched wire formula, the theoretical adjusted value of calculating, and according to
Theoretical adjusted value arranges string length, as structure length of the gold utensil with sub-pieces is fixed, is often difficult string length in Practical Project
It is adjusted to consistent with calculated value.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art and a kind of self-adapting type for providing is double hangs duplex pendency
String.
To achieve these goals, technical solution adopted in the utility model is：
A kind of self-adapting type is double to hang duplex suspension string, including two upper hanging plates being connected on cross arm of tower, respectively with two
Two ball-eyes that individual upper hanging plate is flexibly connected, the dish-type or composite insulator that are connected to two ball-eye lower ends,
The socket-clevis eye of two insulator lower ends is connected to, also including yoke plate, socket-clevis eye lower end is connected on yoke plate, in yoke plate
The tooth bar of an arc is provided with, on the inside of the arc-shaped rack, dentalation is provided with, at least two are provided with yoke plate with the arc
The lower gear of tooth bar engagement, lower gear pass through bearing pin or are bolted on yoke plate, are connected at the two ends of arc-shaped rack
Suspension clamp, is connected with wire clamp on suspension clamp.
Dentalation is provided with the outside of described arc-shaped rack, the gear engaged with the arc-shaped rack is provided with yoke plate.
