Abstract

A wedge-shaped strain clamp for bunched cables comprises a clamp body provided with a wedge-shaped cavity; wherein one end of the clamp body is connected with a pull rod, a wedge block is arranged in the wedge-shaped cavity to match, and the wedge block has an integrated structure; an outer wall of the wedge-shaped cavity of the clamp body is provided with a cable through groove; two narrow side surfaces of the wedge block are both provided with arc recesses which are respectively oppositely matched with an upper part and a lower part of an inner wall of the wedge-shaped cavity, so as to form a core clamping mechanism of the bunched cables; and both the clamp body and the wedge block are manufactured by a composite polymer material. According to the wedge-shaped strain clamp of the utility model, the wedge block has an integrated structure, a cable core can be clamped through cooperation between the arc recesses and the corresponding parts at the inner wall of the wedge-shaped cavity, the wedge-shaped cooperation can tension the cable more and more tightly, so that a slippage does not occur, and the clamping is very reliable; two cable cores are arranged in the each wedge-shaped cavity, so that the bunched cables need not to be twisted oppositely, and an easy and convenient operation can be achieved; in addition, both the clamp body and the wedge block are manufactured by the composite polymer material, thus the wedge-shaped strain clamp has the advantages of convenient production, light weight, no corrosion, labor saving for overhead installation or carrying, and raised construction and installation efficiency.

Description

Bunched cable wedge shape strain clamp
Technical field:
The utility model relates to a kind of electric armour clamp, particularly the fixing wedge shape strain clamp used of bunched cable.
Background technology:
The bunched cable that power transmission and distribution are used generally is two cores or four-core, all need use strain clamp when being fixed on the electric pole with bunched cable is built on stilts.Chinese patent 03210522.3 discloses a kind of four-core centralized cable strain clamp, and the core that utilizes two voussoirs that cooperate in pairs to clamp cable penetrates tensioning in the wedge cavities of wire clamp again, and wedge-like engagement can make cable open tighter and tighter, also not fragile core.But, use two voussoirs that cooperate in pairs to clamp lead and may produce relative slippage, influence the clamping reliability.This strain clamp when mounted also need be with parallel four-core centralized cable to being twisted into square, and be installed in the same wedge cavities of wire clamp, and is more bothersome to turning round, and often needs many people could accomplish, and makes things convenient for inadequately.And general strain clamp all is to adopt made, and weight is big, and cost is high, also possibility corrosion, and built on stilts fitting operation is relatively required great effort, and has reduced efficiency of construction.
Summary of the invention:
To the deficiency of prior art, it is a kind of rational in infrastructure that the utility model provides, the reliable bunched cable wedge shape of clamping strain clamp.
The utility model comprises the clamp that is provided with wedge cavities; Clamp one end is connected with pull bar, and voussoir then places wedge cavities to cooperate, and voussoir is a monolithic construction; The wedge cavities outer wall of clamp is provided with the cable groove; Be equipped with on the two narrow sides of voussoir arc depression respectively with the inwall upper and lower part relative engagement of wedge cavities, constitute the core fixture of bunched cable, and clamp and voussoir all adopt the composite high-molecular material manufacturing.
Voussoir in the utility model is a monolithic construction, utilizes the cooperation clamping cable core of corresponding of inwall of arc depression and the wedge cavities of its narrow side, and wedge-like engagement can make cable open tighter and tighter, can slippage, and clamping is very reliable.Each wedge cavities is installed two cable cores, need not to operate easy and convenient to turning round bunched cable.And clamp and voussoir all adopt the nonmetallic materials manufacturing of composite high-molecular, and be convenient for production, in light weight, can corrosion, built on stiltsly install or carry all more laborsaving, and reduce manipulation strength, construction and installation efficient is provided.
Further specify the utility model below in conjunction with accompanying drawing and embodiment.

Embodiment:
Embodiment 1: present embodiment is used for fixing two core bunched cables, and to shown in Figure 6, clamp 1 is provided with wedge cavities 3 like Fig. 1, and clamp 1 one ends are connected with pull bar 8, and 2 of voussoirs place wedge cavities 3 to cooperate.Voussoir 2 is a monolithic construction; Wedge cavities 3 outer walls of clamp 1 are provided with cable groove 4; Be equipped with on the two narrow sides of voussoir 2 arc depression 5 respectively with the inwall upper and lower part relative engagement of wedge cavities 3; Constitute the core fixture of bunched cable 9, and clamp 1 all adopts the composite high-molecular material manufacturing with voussoir 2.
When installing and using, with each core of the bunched cable 9 of two cores separately, two cores are placed on the inwall upper and lower part of wedge cavities 3 respectively through cable groove 4; Voussoir 2 is also pushed in the wedge cavities 3, and arc depression 5 correspondences on the narrow side of each of voussoir 2 are pushed down the single line core, then tension; Under deadweight and the effect of wedge-like engagement tensile force, can make cable open tighter and tighter; Chucking power to core can be increasing trend, can slippage, and clamping is very reliable.
In the reality, arc depression 5 surfaces on 2 liang of narrow sides of voussoir also can be distributed with a plurality of friction salient points 6, contact more reliable with the core clamping of bunched cable 9 like this.The afterbody of voussoir 2 is connected with lanyard 7 one ends, and lanyard 7 other ends are connected on the pull bar 8, constitutes the voussoir falling-proof apparatus, and voussoir 2 can not drop in built on stilts operation process like this.8 on pull bar is to be used for being connected with other gold utensil whole wire clamp is fixed on electric pole.
Embodiment 2: present embodiment is used for fixing four-core centralized cable, and to shown in Figure 10, the basic structure of present embodiment is identical with embodiment 1 like Fig. 7, but wedge cavities 3 has two, is positioned at the both sides of clamp 1, and voussoir 2 is corresponding also to have two.
When installing and using, with each core of the bunched cable 9 of four-core separately, per two cores are placed in the wedge cavities 3 and are basic identical with 2 cooperation clampings of a voussoir and embodiment 1.The inwall upper and lower part of the wedge cavities 3 of present embodiment is an arc surface, contacts with the core of bunched cable 9 like this to fit better, and clamping is more abundant.
