Abstract
The utility model discloses a carbon fiber composite core wire dedicated tension hardware which comprises an outer sleeve and a connecting ring. A blocking block with a hole is arranged in the middle of the outer sleeve and divides an inner cavity of the outer sleeve into two cavities. A wedge clamp seat whose end part abuts against the blocking block is arranged in one cavity. A wedge clamp which clamps a carbon fiber composite core is arranged in the wedge clamp seat. The connecting ring is provided with a connecting part which extends into the outer sleeve. The end part of the connecting part extends into the wedge clamp seat, and the connecting part is in screw cooperation with the outer sleeve. An inner liner tube is arranged in the other cavity. The carbon fiber composite core wire dedicated tension hardware can be well cooperated with a carbon fiber composite core wire. A normal pressure welding steel tube is changed into the cooperation structure of the wedge clamp seat and the wedge clamp. Self-locking can be realized. The 'more and more tight' effect exists in a use process. The connection effect is good, thus the carbon fiber composite core wire can be well used in the electric power industry.
Description
Technical field
The utility model relates to a kind of link of carbon fiber composite core wire, the special-purpose strain hardware fitting of especially a kind of carbon fiber composite core wire.
Background technology
Along with the development of China's economic construction, electricity needs constantly increases, and cable is increasing as the critical piece demand of delivery of electrical energy, and China is used for construction and the transformation of thousands of kilometers transmission line every year with 1,000,000 tons wire.Mostly the cable conductor of present domestic usefulness is steel reinforced aluminium conductor and aluminium alloy conductors steel, the weight of these wires is larger, resistance is larger, from and cause the transmission of electricity expense high, and operating temperature is lower, can not adapt to the operation under hot conditions, so electric power transfer becomes " bottleneck " of electric power industry development, the overhead cable wire is being studied to replace traditional steel reinforced aluminium conductor by various countries.
Thus, people have invented the tensile strength height, quality is light, the carbon fiber composite core wire of good endurance, but studies show that, because the carbon fiber composite core wire structure has particularity, strain hardware fitting commonly used should not use, and it is relatively poor to connect effect, therefore is necessary to invent a kind of special-purpose gold utensil that connects better effects if.
Summary of the invention
The purpose of this utility model is design for the deficiency that solves above-mentioned technology a kind of easy for installation, connects the special-purpose strain hardware fitting of carbon fiber composite core wire of better effects if.
The special-purpose strain hardware fitting of carbon fiber composite core wire that the utility model is designed, comprise outer tube and draw-barring, described outer tube middle part is provided with a porose barrier piece inner chamber of outer tube is divided into two chambers, be provided with the wedge shape holder that end and described barrier piece offset in one of them chamber, be provided with the wedge grip that carbon fiber complex core is clamped in the described wedge shape holder; Described draw-barring is provided with a connecting portion that stretches into outer tube, and this connecting portion end is stretched into and is threaded engagement between wedge shape holder and connecting portion and the outer tube; In the another one chamber, be provided with internal lining pipe.
As preferably: the front end of described wedge grip exposes described wedge shape holder.
The special-purpose strain hardware fitting of the carbon fiber composite core wire of the utility model gained can match with carbon fiber composite core wire better.During use, first wire is inserted internal lining pipe and install internal lining pipe, insert carbon fiber core at the wedge shape holder again, then the taper end of wedge grip is clamped carbon fiber core and insert in the wedge shape holder, then coupling ring is screwed in the wedge shape holder, screw up with a wrench and namely finish the carbon fiber core connection, carry out crimping in outer tube sleeve at last and get final product.The special-purpose strain hardware fitting of this carbon fiber composite core wire, conventional crimping steel pipe is changed into the fit structure of wedge shape holder and wedge grip, can realize self-locking, the effect that in use has " drawing tighter and tighter ", therefore connect better effects if, thereby so that carbon fiber composite core wire can use in power industry better.
Description of drawings
Fig. 1 is embodiment 1 structural representation;
Among the figure: outer tube 1, draw-barring 2, barrier piece 3, wedge shape holder 4, wedge grip 5, connecting portion 6, internal lining pipe 7, carbon fiber complex core 8, wire 9.
Embodiment
The utility model will be further described by reference to the accompanying drawings below by embodiment.
Embodiment 1:
As shown in Figure 1, the special-purpose strain hardware fitting of the described carbon fiber composite core wire of present embodiment, comprise outer tube 1 and draw-barring 2, described outer tube 1 middle part is provided with a porose barrier piece 3 inner chamber of outer tube 1 is divided into two chambers, be provided with the wedge shape holder 4 that end and described barrier piece 3 offset in one of them chamber, be provided with the wedge grip 5 that carbon fiber complex core 8 is clamped in the described wedge shape holder 4; The front end of described wedge grip 5 exposes described wedge shape holder 4, and described draw-barring 2 is provided with a connecting portion 6 that stretches into outer tube 1, and these connecting portion 6 ends are stretched into and are threaded engagement between wedge shape holder 4 and connecting portion 6 and the outer tube 1; In the another one chamber, be provided with internal lining pipe 7.
The special-purpose strain hardware fitting of the described carbon fiber composite core wire of present embodiment can match with carbon fiber composite core wire better.During use, first wire 9 is inserted internal lining pipe 7 and installs internal lining pipe 7, insert carbon fiber core at wedge shape holder 4 again, then the taper end of wedge grip 5 is clamped carbon fiber core and insert in the wedge shape holder 4, then coupling ring is screwed in the wedge shape holder 4, screw up with a wrench and namely finish the carbon fiber core connection, carry out crimping in outer tube sleeve at last and get final product.The special-purpose strain hardware fitting of this carbon fiber composite core wire, conventional crimping steel pipe is changed into the fit structure of wedge shape holder 4 and wedge grip 5, can realize self-locking, the effect that in use has " drawing tighter and tighter ", therefore connect better effects if, thereby so that carbon fiber composite core wire can use in power industry better.
Specific embodiment described herein only is to design of the present utility model explanation for example.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
