Abstract
The invention discloses a pre-twisted type tension-resistant armor clamp for a large span. The pre-twisted type tension-resistant armor clamp comprises an asymmetric triangular yoke plate and PS type hanging plates, the two bottom corners of the asymmetric triangular yoke plate are connected with a triangular yoke plate and adjusting plates through ZBD type hanging plates, the two bottom corners of the triangular yoke plate and the end portions of the adjusting plates are connected with one ends of the PS type hanging plates through Z type hanging plates respectively, thimbles are connected to the inner sides of the other ends of the PS type hanging plates through bolts, a set of pre-twisted wires is connected to each thimble, bent portions of the three sets of pre-twisted wires are nested into the thimbles, and the other parts of the three sets of pre-twisted wires are in the shape of a helix tube. The pre-twisted type tension-resistant armor clamp has the advantages that the design mode of three split yoke plates is adopted by the tension-resistant armor clamp, the phenomenon that tightness of three sets of pre-twisted wires of an optical cable to be tensioned is not consistent is effectively avoided, distribution of tension-resistant values of a line is more even, the line can bear larger force, erection of towers is reduced, line laying difficulty and cost are greatly lowered, and safety of construction staff is improved.
Description
Technical field
The present invention relates to overhead transmission line equipment, be specifically related to the preformed strain hardware fitting of a kind of Great span.
Background technology
In order to adapt to people's increasing rapidly electricity needs, common way sets up pylon to carry out extension wire laying, this just cause pylon to set up input cost higher, particularly in ocean, high mountain and the larger place of crowd activity's density, certainly will pylon be caused to set up difficulty high, affect laying progress, the safety of workmen is also difficult to be protected simultaneously.If suitably reduce pylon quantity, requiring the strain insulator of cable will be very high, traditional pre-hinged strain clamp stranded go out circuit do not reach this strain insulator requirement far away, and the distribution on the line of strain insulator force value is also uneven.
Summary of the invention
It is reasonable that technical problem to be solved by this invention is to provide a kind of compact conformation, the preformed strain hardware fitting of the uniform Great span of tension Distribution value.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
The preformed strain hardware fitting of a kind of Great span, comprise asymmetric triangle yoke plate and PS type link plate, two bottom corner portions of asymmetric triangle yoke plate are connected with triangle yoke plate and adjustment plate respectively by ZBD type link plate, two bottom corner portions of triangle yoke plate are connected respectively by Z-type link plate one end with PS type link plate with the end of adjustment plate, capel has been bolted inside the other end of PS type link plate, each capel is connected to one group of preformed armor rods, the bending part of three groups of preformed armor rodses is nested on capel, remainder helically tubulose.
Wherein, above-mentioned triangle yoke plate is isoceles triangle shape.
Compared with prior art, advantage of the present invention is: this strain hardware fitting adopts the design of tripartition yoke plate, effectively prevent the generation of optical cable to be tensioned three groups of inconsistent situations of preformed armor rods elasticity, the tension Distribution value of circuit evenly, larger power can be born, thus reduce setting up of pylon, greatly reduce difficulty and the cost of track laying, improve the safety of workmen.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention;
Fig. 2 is plan structure schematic diagram of the present invention.

Embodiment:
As shown in Figure 1 to Figure 2, the preformed strain hardware fitting of a kind of Great span, comprise asymmetric triangle yoke plate 1 and PS type link plate 6, two bottom corner portions of asymmetric triangle yoke plate 1 are connected with triangle yoke plate 3 and adjustment plate 4 respectively by ZBD type link plate 2, triangle yoke plate 3 is in isoceles triangle shape, two bottom corner portions of triangle yoke plate 3 are connected respectively by Z-type link plate 5 one end with PS type link plate 6 with the end of adjustment plate 4, be bolted capel 7 inside the other end of PS type link plate 6, each capel 7 be connected to one group of preformed armor rods.
When the present invention uses, first the top corner portion of asymmetric triangle yoke plate 1 is arranged on pylon, afterwards the bending part of two groups of preformed armor rodses is nested on the capel 7 be connected with triangle yoke plate 3, the remainder of these two groups of preformed armor rodses then helically tubulose be wrapped in be coated with and protect on the optical cable 12 of line preformed armor rods 11, form internal layer hank knotting 10 and middle level hank knotting 9; Afterwards the bending part of the 3rd group of preformed armor rods be nested in and adjust on capel 7 that plate 4 is connected, the remainder of this group preformed armor rods equally helically tubulose is wrapped on middle level hank knotting 9, form outer hank knotting 8, the hank knotting radical of strain insulator is increased, larger force value can be born, extend and set up distance between pylon, thus reduce pylon when transmission lines large crossing is laid set up cost, guarantee the fail safe of constructing further.
Claims (2)
1. the preformed strain hardware fitting of Great span, it is characterized in that: comprise asymmetric triangle yoke plate and PS type link plate, two bottom corner portions of described asymmetric triangle yoke plate are connected with triangle yoke plate and adjustment plate respectively by ZBD type link plate, two bottom corner portions of described triangle yoke plate are connected respectively by Z-type link plate one end with PS type link plate with the end of adjustment plate, capel has been bolted inside the other end of described PS type link plate, each described capel is connected to one group of preformed armor rods, described in three groups, the bending part of preformed armor rods is nested on capel, remainder is tubulose helically.
