Description
Technical field
The utility model is related to technical field of electric power, specially a kind of aluminium alloy strain clamp used for transmission line.
Background technology
Strain clamp be used for corner, continue, and terminal connection.Spiral aluminum-clad steel wire has extremely strong strain insulator intensity, nothing
Concentrated stress, plays a part of to protect and aid in vibration damping to optical cable.A whole set of optical cable strain hardware fitting includes：It is strain insulator preformed armor rods, supporting
Connection gold utensil.Grip of clamp is easy for installation, quick not less than the 95% of the specified tensile strength of optical cable, reduces construction cost.It is suitable
For span≤100 meter, circuit corner<25 ° of ADSS lightguide cable links.Strain clamp is non-for wire or lightning conducter are fixed on
Straight line pole strain insulator string, anchor effect, also for fixing the bracing wire of bracing wire shaft tower.Strain clamp presses structure and mounting bar
The difference of part, can generally be divided into two classes.The first kind：Strain clamp will bear whole pulling force of wire or lightning conducter, and wire clamp is held
Power is not less than the 90 of mounted wire or the specified stretching resistance of lightning conducter, but not as electric conductor.This kind of wire clamp is after wire installation
Can also pull down, separately use.Such wire clamp has bolt-type strain clamp and wedge shape strain clamp etc..Equations of The Second Kind：Strain clamp
In addition to whole pulling force of wire or lightning conducter are born, and as electric conductor.Therefore this kind of wire clamp cannot go again after installing
Dismounting, is also called dead wire folder.Due to being electric conductor, the regulation that the installation of wire clamp has to comply with about installation operation code is conscientiously entered
OK.
Traditional strain clamp compresses the frame mode of wire using pressing plate, there is thrust not enough, causes wire
The defect of sliding, is that this comes into operation we have proposed a kind of aluminium alloy strain clamp used for transmission line, to solve the above problems.
Utility model content
The purpose of this utility model is to provide a kind of aluminium alloy strain clamp used for transmission line, to solve above-mentioned background skill
The traditional strain clamp proposed in art compresses the frame mode of wire using pressing plate, there is thrust not enough, causes
The problem of the defect of line sliding.
To achieve the above object, the utility model provides following technical scheme：A kind of resistance to bracing cable of aluminium alloy used for transmission line
Folder, including installation portion, the top of the installation portion are bolted with clamp nut through the left end for having bolt, the bolt, described tight
Gu pin-and-hole is provided with the left of nut, and pin-and-hole is opened on bolt, U-bolt is welded with the installation portion, on the U-bolt
Pressing plate is connected with, the left and right sides of the pressing plate is equipped with torque nut, and two groups of torque nuts respectively positioned at a left side for U-bolt
Right two ends, the curved end of the U-bolt is provided with briquetting.
Preferably, the left and right two ends of the U-bolt are provided with the external screw thread being adapted with the internal thread of torque nut.
Preferably, the pin for preventing clamp nut from slipping is plugged with the pin-and-hole.
Preferably, the clamping end for being formed between the bottom of the pressing plate and the top of briquetting is arcuate structure.
Compared with prior art, the beneficial effects of the utility model are：The utility model compresses wire using U-bolt,
By left and right torque nut is tightened, pressured piece compresses wire with the movement of U-bolt, and reliable clamping force causes that wire is difficult
Slip.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the utility model side view.
In figure：1 installation portion, 2 bolts, 3 pin-and-holes, 4 clamp nuts, 5U types bolt, 6 torque nuts, 7 pressing plates, 8 briquettings.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of aluminium alloy strain clamp used for transmission line,
Including installation portion 1, the top of the installation portion 1 runs through the left end for having bolt 2, the bolt 2 and is bolted with clamp nut 4, described
The left side of clamp nut 4 is provided with pin-and-hole 3, and pin-and-hole 3 is opened on bolt 2, and U-bolt 5, the U are welded with the installation portion 1
Pressing plate 7 is connected with type bolt 5, the left and right sides of the pressing plate 7 is equipped with torque nut 6, and the two groups of difference of torque nut 6 positions
In the left and right two ends of U-bolt 5, the curved end of the U-bolt 5 is provided with briquetting 8.
Wherein, the left and right two ends of the U-bolt 5 are provided with the external screw thread being adapted with the internal thread of torque nut 6, institute
The pin for being plugged with pin-and-hole 3 and preventing clamp nut 4 from slipping is stated, is formed between the bottom of the pressing plate 7 and the top of briquetting 8
