Specific embodiment
As requested, specific embodiment of the present utility model will be disclosed here.It is to be understood, however, that institute here The embodiment disclosing is only exemplary of the present utility model, and it can be presented as various forms.Therefore, disclose here Detail be not to be considered as limiting, and be merely possible to the basis of claim and as instructing this area Technical staff by practice any appropriate in the way of differently apply representational basis of the present utility model, including using here Disclosed various features and combine here may not clearly disclosure feature.
Embodiment one:
The angle tower 110 that Fig. 2 show at circuit corner uses schematic diagram, and angle tower 110 includes tower body 5 and is arranged on Cross-arm 6 on tower body 5, the wire 7 of corner is articulated on cross-arm 6 respectively.In the present embodiment, wire 7 crank degree is 120 °.
In the present embodiment, cross-arm 6 is combined cross-arm for V-shaped, and the opening of v font connects tower body 5, and apex is freely End, for connecting wire 7.Cross-arm 6 includes two cross arm insulators 8 and free end, two cross arm insulators 8 freely bring out logical Cross end metal fitting 9 fixing.
The partial enlarged drawing of cross-arm free end as shown in figure 3, cross-arm free end include end metal fitting 9, extension device 10 and Bridle wire apparatus 11.Specifically, the both sides in end metal fitting 9 are respectively provided with extension device 10, one end connection end of each extension device 10 Portion's gold utensil 9, the other end is connected with the wire 7 of homonymy.Bridle wire apparatus 11 are fixed on end metal fitting 9, for supporting wire jumper.
In the present embodiment, wire 7 and the angle of cross-arm 6 center line are 60 °, and extension device 10 is horizontally set on free end, and Extension device 10 is 90 ° with the angle of cross-arm 6 center line.The setting of extension device 10 is equivalent to and extends tower body 5 homonymy two corner wire 7 Virtual point of intersection, therefore wire 7 apart from tower body distance increase, wire 7 can be met in the case of not changing cross-arm 6 length Electric clearance and tower body 5 between.
Illustrate for the ease of directly perceived, Fig. 2 and Fig. 1 can be compared, Fig. 1 is the angle tower 100 being not provided with extension device, Fig. 2 is It is provided with the angle tower 110 of extension device 10, both crank degree are identical, and cross-arm length is identical, wire 7 in Fig. 2 in the present embodiment To tower body 5 apart from l2 be more than Fig. 1 in wire 3 arrive tower body apart from l1.
Or using any point on end metal fitting 9 as starting point, draw the parallel lines of wire 7, it is evident that drawn flat The distance of line to tower body 5 is less than the distance that wire 7 arrives tower body 5, that is, using the cross-arm being provided with extension device 10 on angle tower It is easier to meet the electric clearance between wire and tower body.
In the present embodiment, extension device 10 is to be horizontally set on free end, therefore can directly use in extension device 10 and cross-arm 6 Make comparisons in wire clamp angle, it is apparent that extension device can also not exclusively be located in horizontal plane, extension device can offset one in vertical plane Angle, as long as in the projection of horizontal plane, the angle of extension device and cross-arm center line is more than the angle of homonymy wire and cross-arm center line ?.
In addition, the free end in cross-arm 6 is additionally provided with two reinforcements, this two reinforcements includes oblique part 12 and auxiliary Part 13, oblique part 12 and extension device 10 form a V-shaped structure, and that is, oblique part 12 and the end of extension device 10 are fixed on a company V font summit is formed on fishplate bar 14, the other end of oblique part 12 is fixed on end metal fitting 9.The setting of oblique part 12 increases The rigidity of extension device 10 and intensity.Auxiliary member 13 connects oblique part 12 and extension device 10, strengthens oblique part 12 further and prolongs The v font structure that long part 10 is formed, that is, further increase rigidity and the intensity of extension device 10.
Use due to extension device 10, it is to avoid cross-arm 6 is long, so the angle tower being provided with cross-arm 6 is avoided that and leads The ungratified situation of electric clearance between line, and light weight, line corridor is narrow.
The quantity of corner wire is not utility model point of the present utility model, so corner wire can also be division leading Line.In the present embodiment, the outer corner of angle tower 110 is provided with extension device 10 naturally it is also possible to arrange extension device 10 in inside lock. Because in outer corner, first near further away from tower body, inside lock, the wire of corner is directly away from tower body to the wire of corner, So with respect to inside lock, outer corner is with greater need for setting extension device.
Embodiment two:
As shown in Figure 4 and Figure 5, in the present embodiment, extension device 15 is integrally attached on end metal fitting 16 as one, turns Angle wire 17 is connected to the two ends of extension device 15.Different from embodiment one, the extension device 15 of the present embodiment is by five segment length Uneven support 18 is formed by connecting.The bracket assembled of respective numbers can be selected as needed to become the extension device of Len req, meet Electric clearance between wire and tower body.In addition, when extension device needs longer, cleverer in the form of multistage bracket assembled Live.In this enforcement, it is also provided with reinforcement and auxiliary member in the free end of cross-arm, it acts on and structure and phase in embodiment one Same, will not be described here.
Embodiment three:
Angle etc. delivered by cross-arm structure, material and wire that extension device of the present utility model is not intended to limit its application.As Shown in Fig. 6, in the present embodiment, the cross-arm 19 on angle tower 120 is yi word pattern cross-arm, and wire 20 is delivered angle and is 100 °, turns Wire 20 and the cross-arm 19 center line angle at angle are 50 °.In the present embodiment, inside and outside corner is provided with extension device.
Specifically, cross-arm 19 includes cross arm insulator 21 and the free end away from tower body 22, and free end includes end metal fitting 23 and the extension device 24 that is connected with end metal fitting 23.Extension device 24 is a rectangular slab, and its inclination angle in vertical plane is 60 °, and two angles and cross-arm 19 center line between are respectively 70 ° and 110 °.Due between extension device 24 and cross-arm 19 center line Any one angle is both greater than wire 20 and cross-arm 19 center line angle, thus the cross-arm 19 in the present embodiment can meet wire 20 with Electric clearance between tower body 22.
In the present embodiment, end metal fitting 23 one end is sleeve, glueds joint with cross arm insulator 21;One end is connecting plate, with Extension device 24 is fixing.End metal fitting is not utility model point of the present utility model, as long as end metal fitting satisfaction can be with extension device Fixing.In addition the connected mode of extension device and wire is not the utility model point of utility model, is generally in the art Mounted by wire clamp, as long as be capable of wire being connected with extension device.
Technology contents of the present utility model and technical characterstic have revealed that as above it being understood, however, that of the present utility model Under creative ideas, those skilled in the art can make various changes to said structure and material and improve, including independent here Disclose or claimed combining of technical characteristic is combined it will be apparent that including the other of these features.These deformation and/or combination Each fall within the technical field involved by this utility model, and fall into this utility model scope of the claims.
