Abstract
The utility model discloses an adjustable jumper fixing device. The cross section of the jumper fixing device is shaped as an inverted T and formed by splicing two angular steels back to back; the surfaces with the same width of the two angular steels are adhered to each other; straight lines, where the edges of the two angular steels are located, are overlapped. The adjustable jumper fixing device disclosed by the utility model is light, flexible, simple and convenient in installment, can be applied to various angle poles and towers with different voltage levels, and is capable of effectively reducing sag of the jumper and causing the sag of the jumper to be streamlined; the jumper fixing device is compact and beautiful, reduces the size of a tower head, decreases cost and saves resource; in addition, the jumper fixing device reduces floor space, decreases damage to green lands and loss of massif, and is beneficial for protecting the living environment of human beings.
Description
Technical field
The utility model relates to a kind of wire jumper support load, particularly relates to a kind of adjustable wire jumper support load.
Background technology
Along with economic development is more and more faster, the various places need for electricity significantly improves, and high-tension line is also more and more intensive.Receive the influence of topography and planning restriction, and system is with the difference of electric position, the corner ratio of each high-tension line is more and more, and various uses such as angle steel tower, steel pipe pole, steel tube tower are also more and more diversified, causes that wire jumper uses, installation also becomes increasingly complex.
Limit phase cross-arm for phase cross-arm in the corner pole and the big shaft tower of the corner number of degrees generally adopts double jump line string to fix wire jumper.And when using double jump line string, just relate to the hanging point problem.For the corner pole of the different number of degrees, wire jumper dangles the string hanging point apart from difference.Former wire jumper support load need be welded with two blocks of angle steel that two link plates will be arranged up and down; But also will be to the location arrangements wire jumper string link plate and the welding position of angle steel of the wire jumper string hanging point of different corner poles, therefore different corner poles need be processed different wire jumpers supports and carry on a shoulder pole and be complementary with it.And for double bundle conductor, if use fixedly wire jumper of the angle steel arranged up and down, not only strengthened the wire jumper sag, and increased the tower head size, the then corresponding increase of iron tower tower material, the body of engineering is invested corresponding increase.
The utility model content
The purpose of the utility model is to provide a kind of adjustable wire jumper support load.
The purpose of the utility model is implemented by following technical scheme, a kind of adjustable wire jumper support load, and the cross section of said wire jumper support load is " ⊥ " type; Be spliced to form back-to-back by two blocks of angle steel; The identical face of two said angle steel width is fitted each other, and the straight line at the rib place of two said angle steel overlaps, on the face of the two said angle steel of fitting each other; The rectilinear direction that belongs to along the rib perpendicular to two said angle steel is provided with at least two fitting recess; Corresponding respectively said fitting recess is provided with pilot hole on the another one face of two said angle steel, and said pilot hole and the said fitting recess corresponding with said pilot hole be positioned on the same plane, and said fitting recess and said pilot hole are used with card line bolt; Also be provided with at least two pilot holes on the face of the two said angle steel of fitting each other, and be used with U type link.Said pilot hole on the face of the two said angle steel of fitting each other is used according to the hanging point and the said U type link of corner pole, guarantees two not run-off the straights of insulator string string.Said fitting recess, said pilot hole and said card line bolt are used, fixedly wire jumper.
Two said angle steel are the identical Zinc-coated angle steel of length.
Said U type link is two.
The advantage of the utility model is; (1) cross section of wire jumper support load is " ⊥ " type, is spliced to form back-to-back by two blocks of angle steel, the double bundle conductor of vertical arrangement is become at the cross-arm place be arranged in parallel; And increased and jumped string weight; Thereby subdue the wire jumper sag, effectively reduce the tower head size, reduce shaft tower height and weight; (2) the utility model can be regulated according to the corner pole wire jumper string hanging point that dangles, and guarantees two not run-off the straights of insulator string string, thereby does not need to process wire jumper support load separately according to different corner poles again; (3) the adjustable wire jumper support of the utility model load is light and handy, flexible, and simple installation can be applied in the various corner poles of different electric pressures; Can reduce the wire jumper sag effectively, make the wire jumper sag become streamlined, compact, attractive in appearance; Also reduced the tower head size simultaneously, reduced cost, economized on resources.Reduce floor space simultaneously, also reduced greenery patches destruction and massif and run off, helped the protection of environment for human survival.

The specific embodiment
Embodiment 1: a kind of adjustable wire jumper support load, and the cross section of wire jumper support load is " ⊥ " type, is spliced to form back-to-back by two angle steel 1; The identical face of two angle steel, 1 width is fitted each other; The straight line at the rib place of two angle steel 1 overlaps, and on the face of two angle steel of fitting each other, the edge is provided with 5 fitting recess 2 perpendicular to the rectilinear direction at the rib place of two angle steel 1; Corresponding respectively fitting recess 2 is provided with pilot hole 3 on the another one face of two angle steel 1; And pilot hole 3 and be positioned on the same plane with pilot hole 3 corresponding fitting recess 2, fitting recess 2 is used with pilot hole 3 and card line bolt 4, and fixedly wire jumper 6; Also be provided with six pilot holes 3 on the face of two angle steel 1 of fitting each other, and be used with two U type links 5.Pilot hole 3 on the face of two angle steel 1 of fitting each other is used according to the hanging point and the U type link 5 of corner pole, guarantees the 7 not run-off the straights of two insulator string strings.
The length of two angle steel 1 is respectively 3.0m, and is Zinc-coated angle steel.
Claims (3)
1. an adjustable wire jumper support load is characterized in that the cross section of said wire jumper support load is " ⊥ " type; Be spliced to form back-to-back by two blocks of angle steel; The identical face of two said angle steel width is fitted each other, and the straight line at the rib place of two said angle steel overlaps, on the face of the two said angle steel of fitting each other; The rectilinear direction that belongs to along the rib perpendicular to two said angle steel is provided with at least two fitting recess; Corresponding respectively said fitting recess is provided with pilot hole on the another one face of two said angle steel, and said pilot hole and the said fitting recess corresponding with said pilot hole be positioned on the same plane, and said fitting recess and said pilot hole are used with card line bolt; Also be provided with at least two pilot holes on the face of the two said angle steel of fitting each other, and be used with U type link.
