Abstract
A tower head structure of an electric power tension-resistant iron tower comprises a body rod of the tower and a plurality of cross arms transversally arranged on the body rod. Each cross arm comprises two principal rods which are horizontally arranged in parallel. The free end of each principal rod is supported by one inclined supporting rod and the other end of each inclined supporting rod is fixedly arranged on a body, below the corresponding principal rod, of the body rod. A plurality of cross bars are connected between the two principal rods to form a whole. After cross arms of a hanging rod are converted into the cross arms of the inclined supporting rod structure, the body rod height, generated due to the arrangement of the hanging rod on the uppermost cross arm, of the tower can be reduced, the top of each cross arm is a plane, a post type porcelain insulator passing line is adopted, and a gap between every two cross arms is relatively reduced, so that the height of a tower head is reduced and the overall height of the tower is reduced.
Description
Technical field
The utility model relates to a kind of transmission line of electricity facility electric power strain insulator steel tower, especially relates to a kind of tower head structure of electric power strain insulator steel tower.
Background technology
Electric power strain insulator steel tower comprises column foot, tower body and tower head three parts, and tower head is the important component part of transmission line of electricity, plays a part to support and trolley wire, guarantees that electric energy safe is transported to electrical network or user reliably.Before the utility model is made, because the cross-arm of electric power strain insulator steel tower adopts derrick type structure, be subject to upper strata cross-arm suspension rod effect of altitude, the vertical space that need take is relatively large, therefore, this steel tower claims under high condition identical exhaling, height overall increases relatively, and this is especially obvious concerning multiloop steel tower, and the increase of height overall, not only improve cost, returned design, construction etc. and brought a series of impacts.
Summary of the invention
For solving the problems of the technologies described above, the utility model aims to provide a kind of electric power strain insulator steel tower tower head structure of novel structure, use the strain insulator steel tower of this tower head structure, claim under high condition identical exhaling, its height overall is relatively low, thereby be conducive to reduce cost, eliminate design, construction and a series of problems relevant to height overall in use.
For achieving the above object, the utility model has adopted following technical scheme:
This electric power strain insulator steel tower tower head structure, comprise body bar and the horizontal some cross-arms on described body bar of tower, every cross-arm comprises that two levels are to the main material arranging, it is characterized in that: described two horizontal be arrangeding in parallel of main material, the free end of these two main materials is supported by a hound respectively, and the other end of these hounds is fixedly installed on the body club body of described main material below; Between described two main materials, connect into entirety by some horizontal materials.
As preferably, on the roof of described horizontal material, be fixed with column type porcelain insulator, this column type porcelain insulator is arranged on the middle part of the lateral symmetry line of described horizontal material roof, makes gravity be evenly distributed to cross-arm.
As preferably, between described main material and hound, be provided with many bracing pieces.
Beneficial effect: compared with prior art, the utility model makes suspension rod cross-arm into after the cross-arm of hound structure, 1, can reduce the body bar height of topmost cross-arm because of that section of tower suspension rod is set produces, be generally 1 meter of left and right.2, due to derrick type cross-arm, need to realize line by suspension string, therefore, upper and lower cross-arm spacing requires larger relatively, cause tower height to increase, and cross-arm of the present utility model top is a plane, adopt column type porcelain insulator to cross (jumping) line, make the cross-arm spacing can relative decrease, thereby be conducive to reduce tower head height, and then reduce the height overall of tower.
Below in conjunction with accompanying drawing, by an embodiment, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of an embodiment of the utility model.
Fig. 2 is that the K of local cross-arm in Fig. 1 is to structural representation.
Fig. 3 is that in Fig. 1, H is to structural representation, and this figure has only drawn outermost structure.
In figure: column foot 1, tower body 2, tower head 3, cross-arm 31, main material 311, hound 312, bracing piece 313, horizontal material 3111, strain insulator-string 4, column type porcelain insulator 41, strain insulator wire jumper 5.
The specific embodiment
Referring to Fig. 1.This strain insulator steel tower comprises column foot 1, tower body 2 and tower head 3.From top to bottom, have four horizontal cross-arms 31 on tower head 3, every cross-arm 31 is by main material 311, hound 312, bracing piece 313, and some horizontal material 3111(are referring to Fig. 2 and Fig. 3) form.Strain insulator-string 4, the column type porcelain insulator 41 of varying number are set respectively on cross-arm 31 different in size.
Referring to Fig. 2, Fig. 3.Strain insulator-string 4 is separately positioned on the both sides of horizontal material 3111 through junction plate, column type porcelain insulator 41 is arranged on the roof of horizontal material 3111, and while specifically enforcement, this column type porcelain insulator 41 is preferably disposed on the middle part of the lateral symmetry line of horizontal material 3111 roofs.Line was realized on the top of the translateral strain insulator-string 4 of strain insulator wire jumper 5 and column type porcelain insulator 41.
The utility model main innovate point is: changing suspension rod is that the fixing main material 311 of hound 312, employing column type porcelain insulator 41 were realized line.Thereby realize the object that reduces tower height overall.
Above-described embodiment is only for explaining of the present invention opening one's minds, and any simple deformation structure that is subject to its inspiration and make, all should include protection scope of the present invention in.
