Description
Technical field
The present invention relates to a kind of traction connector of carbon fiber compound core conducting wire, belong to electric power system lead traction technique field.
Background technology
Along with the development of electrical network, the capacity-increasing transformation project of transmission line is more and more.That carbon fiber composite core wire has is in light weight, intensity is big, thermal expansion is little, high temperature resistant, advantage such as sag is low, corrosion resistance and good, ampacity are big is as one of novel double capacity conductor, and can utilize existing shaft tower facility, only restringing can increase substantially transmission capacity on old transmission line, is more and more widely used.
Carbon fiber composite core wire is made of carbon fiber core and the multiply outer aluminum steel that twines on the carbon fiber core that interlaces.When carrying out unwrapping wire and Construction of Tension Stringing, usually select a traction net that matches with the carbon fiber composite core wire size earlier, the traction net is sleeved on the outer aluminum steel of wire connecting ends, be clipped on the outer aluminum steel with two metal intermediate plates again, snarl intermediate plate with adhesive tape then, to draw net by the larynx hoop on the traction net is fixed on the outer aluminum steel, preformed armor rods stringing device is connected with the traction net, by pulling preformed armor rods stringing device and traction net carbon fiber composite core wire is carried out unwrapping wire and stringing.Owing to can not reach consistent fully with tractive effort in the stringing with laying tension at unwrapping wire; and when installing and removing the traction net; carbon fiber core takes place in regular meeting and outer aluminum steel is slided race and caused lead pine burst phenomenon; outer aluminum steel also easily weares and teares simultaneously; therefore high to the stringing operation technological requirement; operate loaded down with trivial detailsly, efficiency of construction is low, and construction quality is not high.In addition, the instruments such as larynx hoop, intermediate plate that are installed in the traction net on the carbon fiber composite core wire all adopt crimping to be connected on the lead, after removing the traction net, can not reuse, and have improved construction cost.Above-mentioned defective influences applying of carbon fiber composite core wire to a certain extent.
Summary of the invention
The purpose of this invention is to provide a kind of easy for installation, economical, and can improve the traction connector of carbon fiber compound core conducting wire of construction quality and efficient.
The present invention is that the technical scheme that achieves the above object is: a kind of traction connector of carbon fiber compound core conducting wire, it is characterized in that: comprise sheath, the lead holder, the taper chuck, adapter sleeve and traction piece and rotating shaft, described taper chuck is made of with upper clip two of five equilibrium vertically, the intermediate plate inboard has the arc groove, lead holder and sheath are made of two holders and two guard housing assemblings of five equilibrium vertically, the taper chuck is placed in the pre-small post-large awl arc groove of holder, guard housing is fixedly connected on the front portion of holder, has in the guard housing to match with the core skin and greater than the arc groove of taper chuck small end periphery wall; The shaft shoulder front end face of described traction piece is bearing on the adapter sleeve by bearing and can relatively rotates, be installed in the shaft shoulder rear end face that back seat on the adapter sleeve withstands on traction piece, the rear and front end of traction piece passes adapter sleeve respectively, the rear portion of traction piece has the traction ring seat, the front portion of traction piece is connected with rotating shaft, and the front portion of rotating shaft is screwed on the lead holder and is relative with the large end face of taper chuck.
The present invention is directed to the structure of carbon fiber composite core wire, clamp carbon fiber core by the tapered clamp cover, the awl arc groove of lead holder is interior also can be moved axially because tapered clamp is set on, be the voussoir clamp system, the taper chuck is pushed to the front side of lead holder when rotating shaft, the frictional force of taper chuck is clamped carbon fiber core reliably, and the tensile strength of carbon fiber core is 1.9 times of general steel wire, therefore when mechanical tension directly acts on carbon fiber core, make carbon fiber core can bear enough tension force, therefore can directly draw carbon fiber core draws carbon fiber composite core wire, and carbon fiber composite core wire all can safe construction under drawing tension and the effect of stringing tension force.The present invention clamps the carbon fiber core and the outer aluminum steel of carbon fiber composite core wire respectively by taper chuck and sheath; therefore when the traction carbon fiber core; sheath also clamps outer aluminum steel simultaneously; the slippage and the wearing and tearing of carbon fiber core and outer aluminum steel in to carbon fiber composite core wire unwrapping wire and stringing process have been solved; avoid an outer aluminum steel pine burst lantern phenomenon effectively, protected outer aluminum steel injury-free to greatest extent.Sheath of the present invention, lead holder and taper chuck all adopt modular two-piece construction, and be not only easy to operate, and the taper chuck is that voussoir clamps, and can be suitable for the carbon fiber composite core wire of different size.Simultaneously, each connector does not need to be crimped on carbon fiber composite core wire, after once construction is finished, and the repeated use of detachably getting off, economic, practical, save investment.Lead traction connector of the present invention integrates traction and stringing function, can improve construction technology quality and efficiency of construction.
