Description
Technical field
The present invention relates to technical field of electric power construction, in particular it relates to a kind of pendency glass insulator strings lifting dogs.
Background technology
Insulator is the main body of power transmission sequence insulation, and its purposes is pendency wire and makes wire keep absolutely with shaft tower and the earth
Edge, it should have mechanical strength height, good insulation preformance, jumpy do not affected by intensity, resistance to natural erosion and aging-resistant
Feature.The material of insulator typically uses porcelain and safety glass, the most useful synthetic material.35KV and above defeated
In electric line, conventional suspension insulator assembles bunchiness.Suspension insulator typically forms insulator chain, for different electric pressures
On circuit, the insulator that current China produces is divided into plain edition and anti-fouling type two kinds.Safety glass suspension insulator has size
Little, lightweight, performance is good, metal-ware attachment structure standardization, and has that intensity is high, creep distance big, be difficult to aging, maintenance side
Just advantage.
In prior art, fixture when being risen on overhead transmission line by pendency glass insulator strings, is typically used to block insulator
String carries on lower end, easily aloft rolls in lifting process, wayward.
Summary of the invention
The technical problem to be solved is to provide a kind of pendency glass insulator strings lifting dogs, this pendency glass
Insulator chain lifting dogs can carry out spacing and its side and be provided with the hanger installing static line insulator chain, it is possible to subtract
Rocking in few lifting process.
The present invention solves the problems referred to above and be the technical scheme is that
Pendency glass insulator strings lifting dogs, including the first fixture and the second fixture, described first fixture and the second card
Tool is all in semi-annular shape, and semi-annular shape the first fixture and semi-annular shape the second fixture two ends the most outwards bend, and form an installation
The corresponding mounting ear of ear, described first fixture and the second fixture is flexibly connected by connecting shaft, spiral shell on described connecting shaft one end
Stricture of vagina connects nut；U-shaped hanger it is additionally provided with in described connecting shaft；Respectively set on the upper surface of described first fixture and the second fixture
Being equipped with a coaming plate, outer circumference surface is each provided with a mounting ear, described coaming plate is arc, and its radius is the most gradually
Increase.In this programme, being additionally arranged coaming plate and can connect the retainer ring of static line in lifting dogs, coaming plate is possible to prevent insulation
Substring tilts in pendency glass insulator strings lifting dogs or skews, and two retainer ring connect static line operation and are possible to prevent
Whole pendency glass insulator strings lifting dogs and insulator chain thereon are crooked and aloft rock, make insulator chain stable,
Deliver to high-altitude rapidly.
Preferably, described U-shaped hanger one end is located in the connection between the mounting ear that nut and distance nut are nearest
On axle, the other end is fixed on one end that connecting shaft is not connected with nut.
As a further improvement on the present invention, two mounting ears of described first fixture are additionally provided with gag lever post, described
Being provided with the through hole corresponding with gag lever post on two mounting ears of the second fixture, described gag lever post is located in this through hole, with
Improve the stability of pendency glass insulator strings lifting dogs.
Further, described gag lever post end thread connects limited location nut.
Further, in order to reduce manufacturing cost and the materials of pendency glass insulator strings lifting dogs, described coaming plate is opened
It is provided with multiple through hole.
Further, two retainer ring are separately mounted to the circular arc highest point of the first fixture and the second fixture, and it connects fixing
Rope is convenient and laborsaving when being controlled.
To sum up, the invention has the beneficial effects as follows:
1, the coaming plate of the present invention is possible to prevent insulator chain tilt in pendency glass insulator strings lifting dogs or skew,
And two retainer ring can connect two static lines, when promoting insulator chain, ground is held the behaviour of this static line and high-altitude
As lifting device coordinate slowly unwrapping wire it is prevented that whole pendency glass insulator strings lifting dogs and insulator chain thereon
Crooked and aloft rock, make that insulator chain is stable, deliver to rapidly high-altitude, can effectively prevent in insulator chain lifting process
Rock, good stability；
2, after coaming plate of the present invention uses hollow out to arrange, materials being fabricated and cost can effectively be reduced；
3, present configuration is the compactest, easy to use, low cost.
