Description

Cross tractor
Technical field
Cross tractor the utility model relates to a kind of, belong to power Transmission technical field, in particular in transmission line of electricity and It is overhauled in substation.
Background technique
During transmission of electricity, substation, distribution line stringing hanging wire, since strain insulator weight is big, in bracing wire process In exceptionally straight cannot reach design length again, therefore in hanging wire by the fitting of strain insulator tail portion pull it is some could be complete At mounting.And during stringing, it be in view of conducting wire is to the safe distance of strain insulator, and conducting wire itself can produce at any time The relaxation of deformation such as raw creep, so that the safe distance between conducting wire and insulator is reduced, so it is generally necessary to carrying out to conducting wire Traction is crossed, to offset the relaxation of deformation of conducting wire;It is simple to carry out traction by lifting conducting wire but since the insulator chain having is overweight, It is be easy to cause the deformation of transmission tower cross-arm, substation bus bar framework, distribution cross-arm, so as to cause phase fault accident.
Utility model content
The utility model is directed to above-mentioned problems of the prior art, provides a kind of tractor excessively, solves existing Conducting wire easily causes the deformation of transmission tower cross-arm, substation bus bar framework, distribution cross-arm in distraction procedure in technology.
The technical solution of the utility model is as follows:
It is a kind of to cross tractor, entirety is symmetrically connected and composed by two monomers, the monomer includes connecting plate and fixed plate, The both ends of the fixed plate are respectively equipped with connecting plate, and the inner side edge of fixed plate is along equipped with arc groove, the arc of arc groove The inclined surface being inclined outwardly centered on face;The connecting plate is equipped with steel wire rope fixing part.
Two monomers are linked together by fixing bolt.
The connecting plate of two monomers symmetrically connects integral rear triangular in shape.
The arc groove is semicircle.
The inclined surface of the arc groove and vertical direction are in 45 ° of inclinations.
The steel wire rope fixing part is U bolt, and bolt hole, U bolt is respectively set on the connecting plate of two monomers It is fixed in bolt hole.
The utility model has the advantages that
The round fixture being made up of the arc groove of the utility model can block on the insulator, in traction, pass through Tense wire rope can tense insulator chain, so that conducting wire be made to achieve the purpose that few cross is drawn, ensure that the design in construction Conducting wire degree of speeding, not only improved work efficiency, but also reduced the steel tower as caused by excessive traction and framework deformation.

Specific embodiment
Embodiment
As shown, a kind of cross tractor, entirety is symmetrically connected and composed by fixing bolt 1 by two monomers, it is described Monomer includes connecting plate 3 and fixed plate 4, and the both ends of the fixed plate 4 are respectively equipped with connecting plate 3, the inner side edge edge of fixed plate 4 Equipped with semi-circular recesses 5, the inclined surface 6 being inclined outwardly centered on the arcwall face of semi-circular recesses, inclined surface is in vertical direction 45 ° of inclinations, after two monomers constitute entirety, round fixture and 45 ° of inclined surface and insulator phase that two semi-circular recesses are formed Matching, can block insulator;The connecting plate of two monomers symmetrically connect it is integral after it is triangular in shape, enhancing is whole steady Solidity;Bolt hole 2 is respectively set on the connecting plate of two monomers, U bolt 7 is fixed in bolt hole 2.
The utility model use process is as follows:
When hanging wire, operating personnel puts haulage cable well, is hung near at hanging point using coaster, by two semi-circular recesses Card is on the insulator, relatively good in order to lift effect, is usually stuck on third piece insulator, two monomers are then passed through fixation Bolt fastening fixes haulage cable and U-bolt, tenses haulage cable, improves insulator chain, then draws conducting wire, Achieve the purpose that few cross is drawn, haulage cable is unclamped after hanging wire, opens connecting plate, carries out the work of the next item down stringing.
In the description of the present invention, it should be noted that term " center ", " longitudinal direction ", " transverse direction ", "upper", "lower", The orientation or positional relationship of the instructions such as "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom" "inner", "outside" is It is based on the orientation or positional relationship shown in the drawings, is merely for convenience of describing the present invention and simplifying the description, rather than indicate Or imply that signified device or element must have a particular orientation, be constructed and operated in a specific orientation.Therefore cannot understand For limitations of the present invention.
