Abstract
A kind of tower head structure of electricity strain tower, comprise the body bar of tower and horizontal some cross-arms on body bar, every root cross-arm comprises two levels to the main material arranged, described two main materials are horizontal to be arranged in parallel, 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 below described main material; Entirety is connected into by some horizontal materials between described two main materials.After the present invention makes suspension rod cross-arm the cross-arm of hound structure into, 1, the body bar height of that section tower of topmost cross-arm because arranging suspension rod and producing can be reduced.2, cross-arm top is a plane, adopts column type porcelain insulator to cross line, makes cross-arm spacing can relative decrease, thus is conducive to reducing tower head height, and then reduces the height overall of tower.
Description
Technical field
The present invention relates to a kind of transmission line of electricity facility electricity strain steel tower, especially relate to a kind of tower head structure of electricity strain steel tower.
Background technology
Electricity strain steel tower comprises column foot, tower body and tower head three part, 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 reliably transported to electrical network or user.Before the present invention makes, because the cross-arm of electricity strain steel tower adopts derrick type structure, affect by upper strata cross-arm suspension rod height, 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 concerning especially obvious multiloop steel tower, and the increase of height overall, not only increase cost, return design, construction etc. and bring a series of impact.
Summary of the invention
For solving the problems of the technologies described above, the present invention aims to provide a kind of tower head structure of electricity strain tower 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, thus be conducive to reducing cost, eliminate design, construction and the problem relevant to height overall a series of in use.
For achieving the above object, present invention employs following technical scheme:
This tower head structure of electricity strain tower, comprise the body bar of tower and horizontal some cross-arms on described body bar, every root cross-arm comprises two levels to the main material arranged, it is characterized in that: described two main materials are horizontal to be arranged in parallel, 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 below described main material; Entirety is connected into by some horizontal materials between described two main materials.
As preferably, the roof of described horizontal material is 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, after the present invention makes suspension rod cross-arm the cross-arm of hound structure into, 1, topmost cross-arm can be reduced because of the body bar height of that section of tower arranging suspension rod and produce, be generally about 1 meter.2, due to derrick type cross-arm, need to realize line by suspension string, therefore, upper and lower cross-arm spacing relative requirement is larger, cause tower height to increase, and cross-arm top of the present invention is a plane, column type porcelain insulator is adopted to cross (jumping) line, make cross-arm spacing can relative decrease, thus be conducive to reducing 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 one embodiment of the invention.
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 only depicts 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.
Detailed description of the invention
See Fig. 1.This strain insulator steel tower comprises column foot 1, tower body 2 and tower head 3.From top to bottom, tower head 3 has four horizontal cross-arms 31, every root cross-arm 31 is by main material 311, hound 312, bracing piece 313, and some horizontal material 3111(are see Fig. 2 and Fig. 3) form.Cross-arm 31 different in size is arranged respectively the strain insulator-string 4 of varying number, column type porcelain insulator 41.
See Fig. 2, Fig. 3.Strain insulator-string 4 is separately positioned on the both sides of horizontal material 3111 through junction plate, and column type porcelain insulator 41 is arranged on the roof of horizontal material 3111, and when specifically implementing, this column type porcelain insulator 41 is preferably disposed on the middle part of the lateral symmetry line of horizontal material 3111 roof.The top of the translateral strain insulator-string 4 of strain insulator wire jumper 5 and column type porcelain insulator 41 realized line.
Main innovate point of the present invention is: changing suspension rod is that hound 312 is fixed main material 311, adopted column type porcelain insulator 41 to realize line.Thus realize the object reducing tower height overall.
Above-described embodiment is only for explaining of the present invention opening one's minds, and any simple deformation structure of making by it inspires, all should include protection scope of the present invention in.
