Description
Technical field
The present invention relates to a kind of protector, particularly a kind of strain insulator pressure connecting pipe for lead wire means of defence.
Background technology
Pressure connecting pipe for lead wire in working line, pressure deficiency, Mo tools Bian Xing No reach due when crimping shaping because of fluid power
Compression ratio, or because new and old wire-connection, work is not in place for purification, strain clamp drainage crab bolt clamp force is not enough the problems such as, Yi Fa
Raw aluminium hydraulic pressed connecting pipe takes out line, fracture, heating burn causes wire to land, and circuit stops to power.Particularly across high-speed railway, highway,
Track traffic and the power line tension type aluminium hydraulic pressed connecting pipe of municipal critical facility, once fracture will trigger a series of serious times
Raw harm.Current safeguard procedures are mostly by installing preformed full tension force wire clamp additional（Preformed full tension force connecting strip）Mode is carried out
Reinforcement, and have enough grip forces.But because its complex structure, length are long, to use equipotential at the strain insulator aluminium hydraulic pressed connecting pipe of live wire road
With electricity installs very inconvenient.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art part, and provide a kind of both firmly light and handy, can both have
Effect will not also go offline and interruption of power supply when solving the problems, such as that strain insulator pressure connecting pipe for lead wire failure is broken, also can be in the powered installation in high-altitude
The strain insulator pressure connecting pipe for lead wire protector of Shi Gengjia Portable safeties.
A kind of strain insulator pressure connecting pipe for lead wire means of defence, there is provided a kind of strain insulator pressure connecting pipe for lead wire protector, described strain insulator
Pressure connecting pipe for lead wire protector includes bearing and part flow arrangement, described bearing include U-shaped draw ring, inner sleeve,
Overcoat, external screw thread is provided with the both ends of U-shaped draw ring, and described overcoat is enclosed within outside inner sleeve, and inner sleeve is arranged on when in use
Inner sleeve is made up of two semicircles on wire near strain clamp, and its internal diameter is equal to wire diameter, and overcoat is made up of two half, often
Individual half has included semicolumn, and lug is distributed with the opening both sides of semicolumn, and lug is spaced apart along the axis direction of semicolumn,
Two lugs of half when two semicolumns close up in being staggered, wherein the lug of a piece of half is embedded in another half
In interval between two lugs, through hole is provided with lug, through hole when two half are closed up on lug connects, half semicircle
The internal diameter of post is equal to the external diameter of inner sleeve, and nut check is used in the two ends of U-shaped draw ring through the lug of overcoat during work；Described divides
Stream device includes shunting wire clamp and shunt conductor, during work, U-shaped tab rear part set is penetrated into wire tension-resistant aluminium hydraulic pressed connecting pipe steel anchor ring,
The two screw rods of front end use nut check after penetrating overcoat both sides lug sleeve through hole, then again pacify shunt line one end with shunting wire clamp
Loaded on wire, the other end of shunt line is arranged on electric power line pole tower drainage thread.
When U-shaped draw ring two screw rods nut is tightened, overcoat can axially slide along wire.And the inner sleeve inside overcoat because
Thereafter end face is resisted against original wire tension-resistant aluminium hydraulic pressed connecting pipe aluminum pipe port, and overcoat will not be followed to slide.Therefore, when outside steel
Cover during to original wire tension-resistant axial slip, corresponding radial contracting forces will be produced, oppress aluminum inner sleeve lock ring wire.And
Clamping force increases with the increase of U-shaped draw ring pulling force.Shunt line one end shunting wire clamp is installed on wire again then, point
The other end of streamline is arranged on electric power line pole tower drainage thread.
The outer peripheral face of described inner sleeve is that the inner peripheral surface of described overcoat is along its axle along the pyramidal structure of its axis direction
The pyramidal structure in line direction, both tapers are identical to be used cooperatively.
Inner-outer sleeve is made pyramidal structure, with clamping force with the increase of axial tension increased function.
Described shunting wire clamp is multiple, and the arc that described part flow arrangement is also included positioned at both sides is padded and is located at
Middle barrier liner, arc groove is provided with the both sides of barrier liner, and shunting wire clamp is spaced apart in the axle of arc pad
On line direction.
When in use, using arc pad and barrier liner, original wire and shunt conductor are clamped.
Described shunt conductor and former circuit model identical wire.
Present invention advantage following compared to existing technology in sum：
Strain insulator pressure connecting pipe for lead wire means of defence of the invention, because of the pattern that its load fixture is prepared using interior external conical sleeve, with tight
Hoop power increased function with the increase of axial tension.Again because being to rely on to be serially connected with the wire tension-resistant aluminium hydraulic pressed connecting pipe U-shaped drawing of steel anchor ring
The two screw rods of ring bear wire tension after penetrating its both sides earrings hole, remain appropriate tensioning state, and just in case in wire
Strain insulator aluminium hydraulic pressed connecting pipe will not also produce impulsive force when going offline.The protection gold utensil that wire is electrically shunted is undertaken, shunting line segment is used and original
Circuit model identical wire line segment.Two ends can Ding 3~5 aluminium alloy lock ring wire clamps of Zhuan Catching-rabbits according to the size Gu of fastening force, no
Only clamping force is big, and will not damage wires.The protection gold utensil of wire mechanical tension is undertaken, is only made up of three parts.Lock ring is pressed from both sides
The pattern that tool is prepared using interior external conical sleeve, it is light and handy simple, easy for installation.Undertake the protection gold utensil that wire is electrically shunted, shunt line
Section is short, and two ends are articulated type lock ring wire clamp, is adapted to equipotential electrician one man operation and installs.
The tool design that strain insulator pressure connecting pipe for lead wire means of defence of the invention is used rationally, carry and easy for installation, operation
Process labour intensity is small, and required personnel are few, and efficiency is high, and effect of field application is good, with very strong practicality.
