Description
Technical field
The utility model belongs to power transmission line field of tool, particularly relates to a kind of pre-hinged strain clamp.
Background technology
Strain clamp is used for wire or lightning conducter to be fixed on non-rectilinear shaft tower strain insulator string, the effect of weighing anchor, and is also used for fixing the bracing wire of bracing wire shaft tower.
The difference of structure and mounting condition pressed by strain clamp, can be divided into two classes haply.The first kind: strain clamp will bear whole pulling force of wire or lightning conducter, grip of clamp is not less than 90 of mounted wire or the specified stretching resistance of lightning conducter, but not as electric conductor.This kind of wire clamp can also be pulled down after wire is installed, and uses separately.Such wire clamp has bolt-type strain clamp and wedge shape strain clamp etc.Equations of The Second Kind: strain clamp except bearing whole pulling force of wire or lightning conducter, again as electric conductor.Therefore this kind of wire clamp is once after installing, just can not go dismounting again, is also called dead wire and presss from both sides.Owing to being electric conductor, the installation of wire clamp must be observed about the regulation of fitting operation code is conscientiously carried out.
And existing compression joint type strain clamp produces stress concentration point, Static and dynamic stress static on wire, ground wire is large, is not suitable for severe ambient stress, makes to lead, the vibration of being damaged property of ground wire and fatigue, in addition, installs loaded down with trivial details, adds labour intensity.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of strain clamp to produce stress concentration point, Static and dynamic stress static on wire, ground wire is little, be applicable to severe ambient stress, make to lead, ground wire is from the pre-hinged strain clamp of destructive vibration and fatigue.
The utility model realizes like this, a kind of pre-hinged strain clamp, comprise thimble and stride across the preformed armor rods of thimble, described thimble both sides are provided with linking arm A and linking arm B, and the end of described linking arm A and described linking arm B is bolted, and form fan-shaped conductor chamber in thimble, the bottom surface of thimble is arcwall face, arcwall face is arranged arc elastic pad, preformed armor rods contacts with cushion in thimble through the space of thimble
Further, rotated by axle the utility model scheme the baffle plate A and baffle plate B that arrange vertical stratification in the inner side of fan-shaped conductor chamber and linking arm A and linking arm B boundary linking arm B or linking arm A.
The utility model scheme further, described linking arm A and between described linking arm B and thimble by gemel connection, externally both sides can be realized by hinge and open.
Further, described preformed armor rods is helical structure to the utility model scheme, and both sides preformed armor rods helical structure is stranded to be integrated.
Compared with prior art, beneficial effect is the utility model:
The utility model preformed armor rods structure, while providing enough grip, is distributed in each stress equilibrium and leads, on ground wire, avoids occurring stress concentration point, the anti-vibration performance that pre-hinged strain clamp has had, can protect cable better, extend lifetime of system.
In addition, Static and dynamic stress static on wire, ground wire is little, is applicable to severe ambient stress, makes to lead, ground wire is simple from destructive vibration and fatigue, installation, consistency is strong, free-hand installation does not need erecting tools, improves installation rate and the efficiency of gold utensil, generally, experienced operator installs and only needs a few minutes, owing to being free-hand installation, range estimation just can check installation quality, and the installation stopping to cause because installer uses instrument is inconsistent.
The baffle plate A of the vertical stratification that the utility model adopts and baffle plate B is linkage structure, can by preformed armor rods by baffle plate A, baffle plate A enters in conductor chamber, mouth seals by baffle plate B, when pulling preformed armor rods, baffle plate A is stressed to rotate further, and at this moment preformed armor rods is pushed down by baffle plate B inflexibly, can not rotate, prevent slidably reciprocating of preformed armor rods.
Accompanying drawing explanation
Fig. 1 is the device structure schematic diagram that the utility model embodiment provides;
Fig. 2 is the side structure schematic diagram of the thimble in Fig. 1 of providing of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1 with Figure 2, a kind of pre-hinged strain clamp, comprise thimble 1 and stride across the preformed armor rods 2 of thimble 1, described thimble 1 both sides are provided with linking arm A6 and linking arm B5, linking arm A6 is connected by bolt 3 with the end of described linking arm B5, fan-shaped conductor chamber 10 is formed in thimble 1, the bottom surface of thimble 1 is arcwall face, arcwall face is arranged arc elastic pad 11, preformed armor rods 2 contacts with cushion in thimble 11 through the space of thimble 1, the baffle plate A9 and baffle plate B7 that arrange vertical stratification are rotated in the inner side of fan-shaped conductor chamber 10 linking arm B5 or linking arm A6 corresponding to linking arm A6 and linking arm B5 boundary by axle 8.Described linking arm A6 and being connected by hinge 4 between linking arm B5 with thimble 1, can be realized externally both sides by hinge 4 and open.Preformed armor rods 2 is helical structure, and both sides are preformed to be strandedly integrated.
During use, bolt is unclamped, linking arm A and linking arm B is outwards broken into two with one's hands, meanwhile, preformed armor rods is put into the sector shaped conductor chamber of thimble, now first baffle plate A is pressed into by preformed armor rods, the baffle plate A of vertical stratification and baffle plate B is linkage structure, baffle plate A enters in conductor chamber, and mouth seals by baffle plate B, when pulling preformed armor rods, baffle plate A is stressed to rotate further, at this moment preformed armor rods is pushed down by baffle plate B inflexibly, can not rotate, and prevents slidably reciprocating of preformed armor rods.
Then be bolted after linking arm A and linking arm B being broken back and be integrated.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
