Description
Technical field
The utility model belongs to aerial optical cable assorted golden tool technical field, and in particular to a kind of frame for extremely frigid zones
The clamping hoop type suspension clamp of empty OPGW optical cable.
Background technique
Conventional bolt type, compact type fitting are due to using bolt fastening, in overhead transmission line after OPGW optical cable longtime running
It is easy to produce creep and fastening bolt loosens and grip of clamp is caused to reduce, or stress is generated due to wire clamp discontinuity
Concentration phenomenon.Due to the tension imbalance of route lever (tower) two sides, when occurring big density occur on exceedingly odious natural charm or route
Icing when, the unbalanced tensile force aggravation of bar (tower) two sides, in overhead transmission line, OPGW optical cable fatigue damage is all under normal circumstances
Occur on the region that across OPGW optical cable is in contact with fitting, i.e. highly dynamic bending stress generally occurs for the fatigue of OPGW optical cable
And the place that high static compression is concentrated jointly.In line start deicing device, when being recycled by thawing, may go out
Phenomena such as existing OPGW optical cable cracks, is stranded, causes line accident, it is also possible to so that bar (tower) is collapsed, cause huge economic losses.
Utility model content
The purpose of this utility model is to provide a kind of clamping hoop type catenaries of aerial OPGW optical cable for extremely frigid zones
Folder, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides the following technical solutions: a kind of aerial OPGW for extremely frigid zones
The clamping hoop type suspension clamp of optical cable, including alclad and rubber inserts, two alclads are opposed to be stuck in outside scattered
On layer preformed armor rods, the outer layer preformed armor rods are wrapped in outside OPGW optical cable, and the alclad is clamped on inside clip, the clip
Top be bolted on U-shaped link, the U-shaped link is bolted on hardware, and the outer layer is pre-
Inside is embedded with rubber inserts at the dispersion of hank knotting.
Preferably, internal layer preformed armor rods are wound on the periphery of the OPGW optical cable.
Preferably, the rubber inserts is arc-shaped plate structure, and the rubber inserts is stuck on internal layer preformed armor rods.
Preferably, earth cord has also been bolted on the alclad, the earth cord both ends are fixed to be connected
It is connected to connecting terminal.
The technical effect and advantage of the utility model:
Internal layer preformed armor rods and outer layer preformed armor rods are designed using helical structure, and appearance is consistent with OPGW optical cable appearance after installation,
The preformed armor rods moment is in the state for the more drawing the more tight after it is installed, and avoids traditional fitting and generates creep after longtime running
And grip reduces, grip is uneven and the problems in generates stress collection, passes through internal layer preformed armor rods and outer layer preformed armor rods phase interaction
With will can be uniformly distributed in biggish region to the static compression of OPGW optical cable, and in the protection of rubber inserts
Under, local compression is reduced, the bending stiffness of OPGW optical cable Yu fitting contact area is enhanced, is weakened in these regions by micro-
Dynamic bending stress caused by wind shake is dynamic.Compared with traditional fixed form, hence it is evident that static and dynamic stress on OPGW optical cable is reduced,
It improves OPGW optical cable to be in contact with fitting severe ambient stress on region, makes the vibration of OPGW optical cable damage and tired
Labor especially in the exceedingly odious weather conditions of extremely frigid zones is amenable to that the disconnected of OPGW optical cable will not be generated under thawing circulation
It splits a burst phenomenon, preferably the probability of happening of accident that causes of reduction fitting.

Specific embodiment
Below in conjunction with the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear, complete
Site preparation description, it is clear that the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
Every other embodiment, fall within the protection scope of the utility model.
As shown in Figs 1-4, a kind of clamping hoop type suspension clamp of the aerial OPGW optical cable for extremely frigid zones, including alclad
9 and rubber inserts 10, two alclads 9 are opposed to be stuck on scattered outer layer preformed armor rods 3, the outer layer preformed armor rods 3
It is wrapped in outside OPGW optical cable 1, the alclad 9 is clamped on inside clip 8, and the top of the clip 8 is bolted on U
On type link 4, the U-shaped link 4 is bolted on hardware 5, the model GU-12S of hardware 5, described
Inside is embedded with rubber inserts 10 at the dispersion of outer layer preformed armor rods 3, and rubber inserts 10 is made of ethylene propylene diene rubber.
Internal layer preformed armor rods 2 are wound on the periphery of the OPGW optical cable 1, internal layer preformed armor rods 2 and outer layer preformed armor rods 3 are spiral shell
Winding arrangement is revolved, the presence that can be self-possessed in running tension, cable, internal layer preformed armor rods 2 and 3 moment of outer layer preformed armor rods are in more drawing
Tight state, avoid traditional fitting generate creep and bolt looseness after longtime running and grip reduce, grip it is uneven
The problems in and generate stress collection.Internal layer preformed armor rods 2 and 3 main raw material(s) of outer layer preformed armor rods are high-intensitive aerolite silk,
Main component is that elements, the heat-resistant antifriction corrosion resistances such as aluminium, magnesium, zinc, strontium are excellent.
The rubber inserts 10 is arc-shaped plate structure, and the rubber inserts 10 is stuck on internal layer preformed armor rods 2, is increased
The strong bending stiffness of OPGW optical cable and fitting contact area, weakens and answers in these region dynamic bendings as caused by aeolian vibration
Power.
Earth cord 6 is also bolted on the alclad 9,6 both ends of earth cord are fixedly connected to
