Description
Technical field
The utility model relates to a kind of strain insulator gold utensil, relates in particular to the wedge shape strain clamp that a kind of fixed cable is used.
Background technology
Strain clamp is for fixed cable, bearing cable strain, and cable is hung gold utensil to strain insulator-string group or the shaft tower.Strain clamp is different by structure and mounting condition, and can be divided into two classes: first kind strain clamp will hold whole pulling force of lead, lightning conducter and backguy, and the wire clamp grip should be not less than and be mounted 90% of lead or the specified stretching resistance of lightning conducter, but does not make conductor.This class wire clamp has screw bolt-type strain clamp and wedge shape strain clamp.The characteristics of such wire clamp are can pull down after lead is installed, and use separately; The second class strain clamp is except will holding the whole pulling force of lead and lightning conducter, again as conductor.These class wire clamp characteristics are can not dismantle after installing, and claim the dead wire folder again.Wherein, the wedge shape strain clamp designs and produces according to " wedge " principle.Under the power of the splitting effect of wedge, steel strand wire are locked in the wire clamp.After steel strand wire are installed in the wire clamp, the pulling steel strand wire, chock and steel strand wire export slippage with pressing from both sides barrel simultaneously along the line to wire clamp, and more draw tightlier, are locking state gradually.The characteristics of wedge shape strain clamp are to install and remove conveniently, and after wire clamp installed, wire clamp outlet termination and load line can or adopt the steel wire clamp that the termination is fixed at tangent point with No. 8 galvanized iron wire tightens.
Chinese patent 03210522.3 discloses a kind of four-core centralized cable strain clamp, and the core that this strain clamp utilizes two voussoirs that cooperate in pairs to clamp cable penetrates tensioning in the wedge cavities of wire clamp again.The shortcoming of this strain clamp is the tensioning that can only be used for four-core centralized cable, can't carry out tensioning to the cable of other core numbers.
Chinese patent 201110334211.5 discloses a kind of bunched cable wedge shape strain clamp.This strain clamp is made up of the clamp that is provided with wedge cavities and the voussoir that is arranged in the wedge cavities, and its voussoir is monolithic construction, and the narrow wall in voussoir both sides is provided with the clamp groove.The shortcoming of this strain clamp is that the voussoir both sides must accompany the stress balance that cable adopts the assurance voussoir simultaneously, and namely this wire clamp can only be used for having the tensioning of paired core cable.
At above-mentioned deficiency, need a kind of wedge shape strain clamp of development, it uses the restriction that should not be subjected to the cable core number, to improve the scope of application of wedge shape strain clamp.
