Description
Technical field
ADSS optical cable of the present invention short span taper strain clamp, belongs to ADSS optical cable field engineering field.
Background technology
At present, ADSS optical fiber cable fitting almost all uses preformed armor rods gold utensil, because the advantage such as its simple installation, grip be even, serves the irreplaceable effect of other type gold utensil, but preformed armor rods gold utensil also has shortcoming, on 10KV and following low-voltage circuit, preformed armor rods gold utensil easily causes security incident in work progress, this is because the feature of 10KV and following low-voltage circuit causes, its shaft tower height is low, optical cable hanging point and the distance of line of electric force of design are closer, adding these circuits to be generally in city in complex environment, when practice of construction, in order to avoid being hung up by oversize vehicle and machinery, optical cable can be hung toward high further, actual hanging point is just close to cross-arm sometimes, and the distance between line of electric force is less than 1m, this is a distance very easily had an accident, and in work progress, many times need to operate preformed armor rods aloft, the shortest preformed armor rods length generally also has about 1.5m, work high above the ground personnel slightly do not note touching electric wire and cause electric shock accidents twining in the process tying up or untie preformed armor rods, in fact such accident happens occasionally, when especially processing disconnected cable fault, generalized case is all hot line job, there is very large hidden danger, meanwhile, the adaptability of pre-twisted line hardware is poor, and a kind of optical cable of external diameter can only join a kind of preformed armor rods, otherwise grip does not reach requirement, uses limitation very large, quite inconvenience.
Summary of the invention
Instant invention overcomes the deficiency that prior art exists, provide ADSS optical cable short span taper strain clamp, wire clip body and combination voussoir are with taper fit, grip can reach about 11KN, with 100m span, the specified tensile strength of ADSS optical cable under the meteorological condition of 10mm ice thickness is consistent, under same grip, gold utensil body length is 1/4th of preformed armor rods gold utensil, can install on the ground, also can aloft install, easy construction safety, eliminate the potential safety hazard because gold utensil touching electric wire in work progress causes, and the electric system ADSS optical cable of various outer diameter can be adapted to.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: ADSS optical cable short span taper strain clamp, comprise wire clip body, combination voussoir and link, described wire clip body comprises shell body and intraformational bed, described shell body is bottomless truncated cone shell structure, described intraformational bed is the thin layer being fixed on shell body inside surface, its structure adapts in shell body inside surface, described wire clip body is axle place plane dimidiation centrally, and it is hinged by some hinges, the corresponding side of described hinge is provided with some trip bolts, described combination voussoir is arranged at wire clip body inside, the inside surface of its outline and intraformational bed adapts, described combination voussoir is made up of several voussoir bodies, the axis of described voussoir body winding clamp body is uniformly distributed and forms fiber channel, gap is left between described voussoir body, described link is fixedly installed on wire clip body rear portion.
Described fiber channel inwall is provided with micro-husky dot structure.
Described shell body is high-strength aluminum alloy material, and described intraformational bed and combination voussoir are weatherability engineering plastics.
Described fiber channel is changeable channel, and diameter is between 9mm ~ 15mm.
The voussoir body number of described combination voussoir is six.
The beneficial effect that the present invention compared with prior art has is:
1, material of the present invention is the same with short span ADSS cable jacket, belong to weatherability engineering plastics, same material make the adhesiveness on itself and optical cable surface and associativity better, and fiber channel inside surface is designed with micro-husky dot structure, significantly shorten in the length of same grip drop wire clip body, therefore greatly reduce the probability being touched the security incident that electric wire causes in work progress by gold utensil.
2, gap is left between voussoir body of the present invention, elasticity between voussoir body is connected, effectively can increase like this and balance the friction force between voussoir body and optical cable, make to combine voussoir forms homogeneous constant grip to optical cable, gap simultaneously between voussoir body can adjust, the diameter of the fiber channel that voussoir body is combined to form can change within the specific limits, automatically can adapt to the optical cable of various outer diameter.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described further.

Fig. 2 is right view of the present invention.
In figure, 1 be wire clip body, 2 for combination voussoir, 3 be fiber channel, 4 be link, 5 be holding screw, 6 be hinge, 7 be optical cable, 11 be shell body, 12 be intraformational bed, 21 for voussoir body.
Embodiment
As Fig. 1, shown in Fig. 2, ADSS optical cable of the present invention short span taper strain clamp, comprise wire clip body 1, combination voussoir 2 and link 4, described wire clip body 1 comprises shell body 11 and intraformational bed 12, described shell body 11 is without the bottomless truncated cone shell structure in top, described intraformational bed 12 is for being fixed on the thin layer of shell body 11 inside surface, its structure adapts in shell body 11 inside surface, described wire clip body 1 is axle place plane dimidiation centrally, and it is hinged by some hinges 6, the described corresponding side of hinge 6 is provided with some trip bolts 5, it is inner that described combination voussoir 2 is arranged at wire clip body 1, the inside surface of its outline and intraformational bed 12 adapts, described combination voussoir 2 is made up of several voussoir bodies 21, the axis of described voussoir body 21 winding clamp body 1 is uniformly distributed and forms fiber channel 3, gap is left between described voussoir body 21, described link 4 is fixedly installed on wire clip body 1 rear portion.
Described fiber channel 3 inwall is provided with micro-husky dot structure.
Described shell body 11 is high-strength aluminum alloy material, and described intraformational bed 12 and combination voussoir 2 are weatherability engineering plastics.
Described fiber channel 3 is changeable channel, and diameter is between 9mm ~ 15mm.
Voussoir body 21 number of described combination voussoir 2 is six.
Concrete using method:
Described wire clip body 2 is made up of two parts of symmetry, the side hinge 6 of parting plane carries out hinged, opposite side fastening bolt 5 is connected, wire clip body 2 is opened during installation, optical cable 7 is positioned over fiber channel 3, share wire clip body 2 again, fix with fastening bolt 5, at this moment optical cable 7 can slide in fiber channel 3, then combination voussoir 21 is knocked with hammer, push combination voussoir 21 to smaller diameter end from frustum of a cone larger diameter end gradually, until hold optical cable 7 tightly, at this moment just complete this device and optical cable 7 is held to the installation of embracing.
Embodiment:
