Description
Technical field
The strain clamp that the present invention relates in a kind of overhead transmission line and on transformer station's shaft tower JRLX/T (ACCC) carbon fiber lead is connected, fixes, strains.Classify in H02G7/02, relate to the electric armour clamp that in power transmission and transformation line, is provided with, promptly regulate and keep the device technique field of mechanical tension.
Background technology
Strain clamp be in the overhead transmission line and transformer station's shaft tower on to lead connect, the electric armour clamp of fixing, tension.At present, domestic transmission line all adopts steel core, aluminium stranded conductor, steel reinforced aluminium conductor, and the one, be easy to generate magnetic hysteresis and damage consumed power; The 2nd, contact-making surface is less, and it is uneven to peg graft, easily heating, grip shakiness; The 3rd, through explosion crimping,, reduced mechanical strength because strong wallop has changed metallographic, it is dangerous to construct.At present in processes such as electric network reconstruction, overhead transmission line, the extensive use of JRLX/T (ACCC) carbon fiber lead.But because JRLX/T (ACCC) carbon fiber wire quality is light, quality is crisp, under the uneven situation of radial force, easily JRLX/T (ACCC) carbon fiber lead is caused damage, even cause the fracture of lead, thereby reduced the bearing capacity of JRLX/T (ACCC) carbon fiber lead composite core along the line direction, at present common strain insulator gold utensil can not satisfy the connection of JRLX/T (ACCC) carbon fiber lead on the tower bar, fixing, tension, etc. requirement, have that length is long, construction is inconvenient, problem such as inconvenience be installed.
Disclosed Chinese patent, wherein: 99225730 " reinforced plastics insulation strain clamps " are to make parts with reinforced plastics, comprise that the structure of pull bar, case, wedge chock is all different." 200720103674.x optical power grounded waveguide U type is adjustable preformed strain clamp ", disclosed is to comprise that rigidity clamps structure and at least one preformed armor rods group.Equally, material is all different with structure." 200720093999.4 tension resisting clip for carbon fiber composite core conductive wire ", it is the structure of establishing the wedge shape holder in the online clip main body, also is that material is different with structure.200720034784.5 " Compound Core Aluminium Strand Cable Expanding Terminal Dead-end Clamp " is disclosed to be that the reinforcement bolt is screwed into excessive pipe front end, utilizes the method for tension force sleeve pipe, aluminium hydraulic pressed connecting pipe, conulite crimping lead.
At first to file 200820136586.4 " polymer alloy high energy-saving strain clamp ",, with regard to its workpiece weight and cost, do not reach desirable degree as yet though on engineering is used, receive very good effect.
Summary of the invention
For solving problems such as the connection of JRLX/T (ACCC) carbon fiber lead on the tower bar, fixing, tension.The object of the present invention is to provide that a kind of grip is bigger, high temperature resistant, water conservancy diversion is effective, easy for installation, can satisfy the strain clamp that JRLX/T (ACCC) carbon fiber lead requires the connection of lead, fixing, tension etc. on shaft tower.
The present invention is by the following technical solutions:
Mainly draw anchor (1) to connect inner cone external screw thread core retainer plate (3), outer cone elasticity sandwich (4), lining (5), sleeve pipe (2) successively and form overall structure by internal thread.
Internal thread draws anchor (1) to be designed to special type member, is that the right side is connected with half hollow cylinder of crimping telescopic chute (104), internal thread (105) at the flat-shaped draw ring (102) of circle retaining (101) left side connecting band long through-hole (103).

Draw half hollow cylinder internal thread (105) of anchor (1) to connect a core retainer plate (3) that is provided with inner cone (302), external screw thread (301) by internal thread.
The outer cone elasticity sandwich (4) that connects a hollow in the middle of the inner cone external screw thread core retainer plate (3), this sandwich (4) be by locking JRLX/T (ACCC) carbon fiber lead composite core (7), thereby connect, fixing JRLX/T (ACCC) carbon fiber lead (6).
The inner cone of inner cone external screw thread core retainer plate (3) is identical with the outer cone tapering of outer cone elasticity sandwich (4), is 0.5～15 degree.
Make JRLX/T (ACCC) carbon fiber lead composite core pass outer cone elasticity sandwich (4) inside, by radial effect power, outer cone elasticity sandwich (4) and inner cone external screw thread core retainer plate (3) are clamped automatically, locking lead composite core, internal thread draws anchor (1) that crimping telescopic chute (104) is set simultaneously, inner cone external screw thread core retainer plate (3) one ends are placed lining (5), sleeve pipe (2) is through hydraulic pressure, lead (6) is connected, be fixed on JRLX/T (ACCC) the carbon fiber conductor strain clamp, finally draw anchor (1) that JRLX/T (ACCC) carbon fiber lead (6) is connected by internal thread, be fixed on the shaft tower.
Because of JRLX/T (ACCC) carbon fiber lead light weight is crisp, can only radial force, in installation process, distortion, bending etc. will damage lead easily; make its fracture, outward appearance length of the present invention is calculated and checking through science, novel structure; reasonable in design, stability is strong, guardwire.Composite core (6) through outer cone elasticity sandwich (4), inner cone external screw thread core retainer plate (3) locking JRLX/T (ACCC) carbon fiber lead can clamp composite core automatically, fix by radial effect power.Internal thread draws anchor (1) one end that internal thread is set, and the surface is provided with the crimping telescopic chute, novel structure, and design science, stable performance, internal thread draws anchor (1) to connect inner cone external screw thread core retainer plate (3), and the one end is provided with swivelling chute, and convenient the installation is convenient to construction.Inner cone external screw thread core retainer plate (3) outer setting crimp groove, internal diameter is conulite from fine to coarse, and is highly polished, matches with outer cone elasticity sandwich (4).
Outer cone elasticity sandwich (4) inside is provided with centre bore, is installed with the lead composite core, and is highly polished; External diameter is a cone from fine to coarse, in the relative intersection in its two ends 4-6 telescopic chute (401) is set evenly respectively, make it clamp composite core (7) when inner radial is stressed, lock lead (6), thereby play the effect of connection, fixing cord at inner cone external screw thread core retainer plate (3).
Advantages such as the present invention has novel structure, design science, good guide performance, stability is strong, grip is stable, cost is lower, construction install convenience, labour intensity are low.
