Hope that transmission line of electricity and environment are lived harmonious one, power cable underground laying is the perfect means of urban electricity supply, the thing followed
Power cable construction project is emerged in multitude, and cable laying condition faces the challenge in complicated region and path, cable large-section lead
Difficulty is laid in increase, and rudimentary technical matters and construction appliance be not suitable with present execution conditions in the past.For this purpose, cable laying construction
Technology and equipment must be upgraded raising.
Cable drawing head device in big load cable laying gravity dragging process, be cable constructions engineering key technology it
One, in the past using bracing wire net, structure power transmission is to produce frictional force to cable cover(ing) by net pressure, has the disadvantage to work as pull strength
When larger, bracing wire net breakdown itself or cable jacket rupture, and cause the failure of traction midway.Therefore, the present inventor is done to this
Further study, develop a kind of three core crosslinked cables device formula traction wire clamp technique, thus this case produces.
The content of the invention
It is an object of the invention to provide a kind of three core crosslinked cables device formula draws wire clamp technique, convenient disassembly can be again
It is multiple to use.
To achieve these goals, technical scheme is as follows：
A kind of three core crosslinked cable device formulas traction wire clamp technique, comprises the steps：
Three-tube type wire clamp is taken, the wire clamp is made up of the steel pipe of three sections of welding finished product fonts, the middle of wire clamp is connected with drawing
Bar；Protective layer is peelled off in one end of cable or insulating barrier exposes wire, by wire pass through steel pipe, steel pipe opening prop up insulating barrier or
Protective layer；The wire for exposing steel pipe opening is broken up and reserves space, pin is inserted in space, tapping wire makes its bending or become
Shape, forms pin and wire and extrudes in steel pipe；Wire to exposing steel pipe opening is carried out after ligation, then will be exposed with adhesive waterproof tape
Wire and steel pipe wind together；After completing above-mentioned steps, cable is drawn by pull bar.
Further, the adhesive waterproof tape of winding after the completion of cable pulling, is removed, then the wire of sawed-off insulating barrier removes disconnected
The wire insulation for falling, longitudinal direction tap wire, and wire departs from steel pipe, and three-tube type wire clamp not damaged is made in follow-up cable uncoiling
With.
Further, the steel-pipe welding is provided with draw ring on the pull bar on pull bar.
Further, the steel pipe inside pipe wall forms the gradient into horn-like structure, all steel pipe internal orifice fillets, three steel pipe positions
Put and be evenly distributed on around pull bar, the axis of steel pipe forms camber angle with the axis of pull bar.
After such scheme, the present invention compared with prior art, with advantages below：
Power transmission form is changed to cable conductor frictional force by cable cover(ing) frictional force, and cable conductor is combined with gold utensil wire clamp, peace
Complete and firm, cable construction loss is reduced, and wire clamp be able to can be reused with execute-in-place, convenient disassembly with cable connection.

Label declaration
Steel pipe 1, pull bar 2, wire 3, pin 4, adhesive waterproof tape 5.
Specific embodiment
The present invention is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
As illustrated, a kind of three-tube type wire clamp that the present invention is disclosed, is made up of the steel pipe 1 of three sections of welding finished product fonts, line
The middle of folder is connected with 2 pull bar 2 of pull bar and is provided with draw ring；1 inside pipe wall of steel pipe forms the gradient into horn-like structure, Suo Yougang
1 internal orifice fillet of pipe, three 1 positions of steel pipe are evenly distributed on around pull bar 2, and 1 axis of steel pipe and 2 axis camber angle of pull bar.Steel
Port inner diameter than cable conductor 3 diameter big 1-3mm of the pipe 1 near cable, the other end are more than more than 5mm.The weldering of steel pipe 1 is close after drawing
Draw ring side camber angle 5, draw ring extends is easy to shackle to connect, and pin is small end head fillet, is facilitated insertion between 3 strands of wire.Three
Tubular type wire clamp adopts No. 10 steel of steel, galvanizing after processing.
Field device technique：
By VJV22-8.7/15-3 × 300 twisted polyethylene cable, head peels off oversheath 170mm, stripping 90mm；
Nuditing wire 390mm, removes surface impurity, respectively three-phase conducting wire 3 is inserted three steel pipes 1 of three-tube type wire clamp,
1 mouthful of steel pipe props up insulating barrier；1 exposed portion wire of loose steel pipe, 3 strands are smash with screwdriver successively three-phase, is stayed between 3 strands of wire
Go out empty gap；Steel pin nail insertion 3 strands gap location of wire, then iron hammer percussion steel pin nail is into 3 depths of wire；Iron hammer longitudinally strikes
3 end of wire is hit, strand bending or deformation is made, steel pin nail and strands is formed and is extruded in steel pipe 1；Reveal bare conductor with iron wire grafting
3, prevent steel pin nail from skidding off and increasing strands extruding force is followed closely with steel pin.Reveal naked part with 5 wrapped cable of adhesive waterproof tape, form waterproof
Protective layer.
After completing above step, by the draw ring of three-tube type wire clamp, preposition joining shackle and anti-lay steel cord, cable is entered and is led
Draw working condition.With apply pulling force, as 1 inwall of steel pipe is the gradient, the wire 3 in steel pipe 1 to 1 inner wall pressure of steel pipe therewith
Increase, wire 3 is increased with 1 frictional force of steel pipe, cable drawing force Jing three-tube type wire clamps pass to cable, characteristic tractive power can be by
Wire 3 allows tension force.
After the completion of cable pulling, shackle and steel wire rope are removed, remove the adhesive waterproof tape 5 of winding, the wire of sawed-off insulating barrier
3, then remove 3 insulating barrier of wire for breaking, longitudinally percussion wire 3, the disengaging steel pipe 1 of wire 3, three-tube type wire clamp not damaged,
