Described side cross-arm is arranged at below earth wire support.
Further, described side cross-arm includes four insulating bars, and described four insulating bars one end outwardly links together,
The other end is then separately fixed on the cranking arm of homonymy.
Further, described cranking arm is formed by connecting by upper three-legged structure and lower triangular structure, the bottom of described upper three-legged structure
Side is connected upward and with middle cross-arm, and its drift angle is down；Described lower triangular structure tilts to inside described tower window, its drift angle court
Upper and be fixedly connected with the drift angle of described upper triangle, two on its base base angle, one with another lower triangular structure of cranking arm
Drift angle be connected, another is connected with tower body part.
The beneficial effects of the utility model are：
This utility model, by prior art is carried out with the analysis of deep corrective measure, through again planning, tentatively sets
Count new pendency and bored and get over tower, this utility model employs that wire is horizontally arranged, method hung by " several " not contour notch cuttype ground wire,
Measures such as " side phase are combined cross-arm ", can smoothly bore more conventional one time and parallel two times ± 800kV circuits, basic realization
Bore " zero restriction " getting over point to path Scheme Choice.This utility model structure is simple, and function is easy, save space, minimizing expropriation of land,
Get over point selection restriction less to boring, substantially realize " zero restriction ", save structural material, reduce and invest.

Specific embodiment
This utility model provides a kind of transmission line of electricity double loop wineglass tower, including tower body 1, tower window 2, side cross-arm 3, middle horizontal stroke
4, two earth wire supports 5 of load.Tower body 1 top is fixed in tower window 2 bottom, and middle cross-arm 4 is horizontally placed on tower window 2 top.Tower window 2 by
The composition of cranking arm that middle cross-arm 4, two being symmetrical set tilt, described two lower ends of cranking arm link together.
In order that tower head size is compacter, side cross-arm 3 is set to compound cross-arm.Compound cross-arm is located at middle cross-arm 4 both sides
Lower section, the construction of each compound cross-arm is：It is extended to inwardly and corresponding four fixing eradication edge of cranking arm including by end points outwardly
Bar.In described four insulating bars two are located at lower end, and are horizontally disposed with, and in addition two are located at upper end, and are connected to ground wire and prop up
At the junction point of frame 5 and cross-arm, end points outwardly hangs with overhanging golden tool string 9.It is computed, for discharging unbalanced tensile force, string is long only
Need 1m, middle mutually utilize tower body 1 structure using conventional V string, make three-phase conducting wire with high.
Described two earth wire supports 5 are obliquely installed respectively in the surface of compound cross-arm, are fixedly connected on one with side cross-arm 3
Rise, described earth wire support 5 end outwardly forms non-boring and gets over shelves ground wire hanging point 6, it is bored with the upper connection point formation of middle cross-arm 4
More shelves ground wire hanging point 7.This utility model hangs method using " several asymmetric staged " ground wire, gets over shelves in non-boring, ground wire adopts
Conventional hanging point, hanging point position is high；And get over shelves using special hanging point in main material boring, hanging point position is relatively low.So both reduced brill
The height of more shelves ground wire, and to get over shelves span little due to boring, can be easily met lead, ground wire wire spacing；Do not transforming simultaneously
On the premise of adjacent steel tower earth wire support 5, meet that " on shaft tower, the distance between two ground wires, are not to be exceeded ground wire and wire
Between 5 times of vertical dimension " requirement.
Described cranking arm is formed by connecting by upper three-legged structure and lower triangular structure, the base of described upper three-legged structure upward and with
Middle cross-arm 4 is connected, and its drift angle is down；Described lower triangular structure tilts to described tower window 2 inner side, its drift angle upward and with institute
The drift angle stating triangle is fixedly connected, two on its base base angle, and a drift angle with another lower triangular structure of cranking arm is even
Connect fixation, another is connected with tower body 1 part.Described two lower ends of cranking arm link together, and upper end is separately so that lower tower
Window 2 middle part is hollow out, and upper end is opening shape.The weight that the gravity of two tower windows 2 itself and two tower windows 2 are born of cranking arm tilting
Power, is delivered to the top of tower body 1 along oblique line, and then the overall stress of described wineglass tower is smoothly transferred on tower body 1, allows
The stress of described wineglass tower is more reasonable, and structure is more stable.Additionally, such design structure is so that the engraving of lower tower window 2 middle part
Empty shape structure is bigger, and so that gas passes through, area is bigger, and tower window 2 is less to the obstruction of air-flow, and makes the support scope of tower window 2
More greatly without increasing the overall wind surface of described wineglass tower so that the structure of described wineglass tower, in addition to simpler, also has
Wind resistance, also further increases wind resistance of the present utility model well.The earth wire support 5 stretching out is avoided that ground wire is straight
Connect contact with upper tower window 2 and occur damage.V-type suspension insulator 8 is arranged in tower window.
Described tower body 1 provides installation for described wineglass tower and supports pedestal.
