Abstract
The utility model provides a combined type high-low cross arm with the drilling and crossing functions. The combined type high-low cross arm is installed at the upper end of a gantry-type stay wire concrete rod and comprises two vertical beams, a horizontal pull rod, a plurality of inclined pull rods, an upper decorated beam, a lower decorated beam and a plurality of hoops. The lower ends of the two vertical beams are fixed to the upper ends of the two concrete rods by utilizing the hoops. The upper decorated beam and the lower decorated beam are planar grid type steel structural members. The lower decorated beam is horizontally arranged between the two concrete rods through the inclined pull rods. The upper decorated beam is horizontally arranged between the tops of the two vertical beams through the inclined pull rods. The combined type high-low cross arm has the advantages that a structure of an existing gantry-type concrete rod can be changed, and the safety distance requirement for crossing a highway, a warehouse, a roof and a distributing line is completely met without the geographical conditions of replacing an iron tower and laying an electrical cable; compensation of occupying lands permanently by foundations is eliminated, the investment is saved, and the work efficiency is improved.
Description
Technical field
The utility model belongs to electric power facility technical field, particularly relates to a kind of combined type height cross-arm that bores more, crosses over function that has.
Background technology
In power system, according to line design standard and circuit operating standard regulation, 35kV electric pressure circuit and the distance between ground of crossing highway can not be less than 6.5 meters.At present, a large amount of main distribution line being formed by 10kV to 35kV concrete bar still existing in vast rural area.Along with economic fast development, existing highway is widened, repairerment, ground are raised, and the reason such as build a house under line all can cause original wire distance to the ground not enough.Therefore,, in order to ensure power circuit safe operation, just the concrete bar of both sides of highway need to be increased.Traditional method is that both sides of highway 35kV concrete bar is removed, and replaces with two base lists and returns 15 meters of lists and return steel tower, so just can accomplish wire to raise, and Shi Qiyu highway keeps enough safe distances.The general self-supporting tower that adopts, its structure comprises basis and iron body more.But while adopting this scheme, design, construction, transportation more loaded down with trivial details, long construction period; Foundation construction need be handled permanent expropriation of land; And in work progress, also need to handle and repair the roads and the reparation of thing on the ground.In addition, change a base steel tower and need to invest as ten thousand yuan of 4-5, also do not comprise basic permanent expropriation of land, take up an area and the expense such as greenery patches reparation temporarily, so appropriate litigation fees is high.
Summary of the invention
In order to address the above problem, the purpose of this utility model be to provide a kind of can meet bore simultaneously crossing highway more, roof, power circuit requirement have brill more, cross over the combined type height cross-arm of function.
In order to achieve the above object, the combined type height cross-arm that bores more, crosses over function that has that the utility model provides is arranged on gate-type bracing wire concrete bar upper end, and it comprises two vertical beams, girt, many diagonal members, top panelgirder, bottom panelgirder and a plurality of anchor ears; Wherein the lower end of two vertical beams utilizes respectively anchor ear to be fixed on the upper end of two concrete bars; Top panelgirder and bottom panelgirder are planar shaped grid type steel construction piece, and its middle and lower part panelgirder is horizontally set between two concrete bar tops by many diagonal members, and top panelgirder is horizontally set between two vertical beam tops by many diagonal members.
The upper end of many described diagonal members is connected to top or the anchor ear of vertical beam simultaneously, and lower end is connected to two ends front-and-back angle or the edge, front and back, middle part of top panelgirder or bottom panelgirder.
Described top panelgirder and the distance between the panelgirder of bottom are 2.2m.
The combined type height cross-arm that bores more, crosses over function that has that the utility model provides has following beneficial effect:
(1) adopt this combined type height cross-arm can change existing door shape concrete bar structure, do not possessing under the geographical conditions such as the steel tower of replacing, power cable laying, thoroughly solved the safe distance requirement of crossing highway, warehouse, roof, distribution line.Crossing highway distance to the ground can be brought up to 7.5 meters; Cross over distribution line and be greater than 3 meters; Leap warehouse, roof vertical distance are greater than 3.5 meters.
(2) cancel the reparation of basic permanent occupation of land, saved investment, both reached the user demand of crossing over, greatly reduced again construction costs.
(3) traditional method completes the once power failure group tower duration needs 1 day, and adopting this device to complete once to have a power failure only to install needs 0.5 day, and operating efficiency improves 2 times, reduces power off time 6 hours.
(4) the one base steel tower body investment of traditional 35kV track replacement is 40,000 yuan, does not also comprise basic permanent expropriation of land, takes up an area and the expense such as greenery patches reparation temporarily, adopts this device price to be no more than 1000 yuan, and can reuse for several times, saves and invests 97.5%.
Accompanying drawing explanation
Fig. 1 has a combined type height cross-arm structural perspective of boring more, crossing over function for what the utility model provided.
The door shape concrete bar overall structure schematic diagram with the combined type height cross-arm that bore more, cross over function of Fig. 2 for being equipped with the utility model to provide.
The specific embodiment
The combined type height cross-arm that bores more, crosses over function that has the utility model being provided below in conjunction with the drawings and specific embodiments is elaborated.
As shown in Figure 1, the combined type height cross-arm that bores more, crosses over function that has that the utility model provides is arranged on gate-type bracing wire concrete bar 7 upper ends, and it comprises two vertical beams 1, girt 2, many diagonal members 3, top panelgirder 4, bottom panelgirder 6 and a plurality of anchor ears 5; Wherein the lower end of two vertical beams 1 utilizes respectively anchor ear 5 to be fixed on the upper end of two concrete bars 7; Top panelgirder 4 and bottom panelgirder 6 are planar shaped grid type steel construction piece, and its middle and lower part panelgirder 6 is horizontally set between two concrete bar 7 tops by many diagonal members 3, and top panelgirder 4 is horizontally set between two vertical beam 1 tops by many diagonal members 3.
The upper end of described many diagonal members 3 is connected to top or the anchor ear 5 of vertical beam 1 simultaneously, and lower end is connected to two ends front-and-back angle or the edge, front and back, middle part of top panelgirder 4 or bottom panelgirder 6.
Described top panelgirder 4 and the distance between bottom panelgirder 6 are 2.2m.
The utility model provides has the combined type height cross-arm that bores more, cross over function in use, arrange on can bottom panelgirder 6 and bore power circuit more, and the 35kV electric pressure circuit of crossing highway is set on top panelgirder 4.
