Description
Technical field
The present invention relates to a kind of transmission line of electricity pole, be specifically related to a kind of transmission line of electricity monomer pillar pole.
Background technology
The construction of transmission line construction tower erection is generally monomer pillar with the structural shape of pole, and this pole is from heavy and light, and longitudinal stability is good, and flexural strength is large, and lateral deformation is little; What pole material generally used has steel standard knot and aluminum standard joint, and steel density is large, and the pole of making is heavier, is unfavorable for mounting or dismounting and carrying.Aluminium density is relatively little, and after the pole of making connects steel flange, weight increases, and is not easy to the severe regional work transmission line construction of artificial installation and carrying, the particularly mountain area of physical features complexity and environment; Along with the progress of material science, galss fiber reinforced resin based composites is that glass fiber reinforced plastic is applied to pole gradually, but glass fiber reinforced plastic pole exists following shortcoming:
(1) modulus of elasticity is low: the modular ratio steel of glass fiber reinforced plastic is little 5 times, and rigidity is lower.
(2) the heatproof phase is not long: glass fiber reinforced plastic generally can not at high temperature use for a long time, and for example general purpose polyester glass fiber reinforced plastic is general only 100 DEG C of following uses; Universal fiber glass epoxy is more than 60 DEG C, but intensity has obvious decline.
(3) easily aging: under the effects such as ultraviolet ray, wind sand sleet, chemical mediator, mechanical stress, performance easily declines.
Summary of the invention
The object of this invention is to provide high, the lightweight transmission line of electricity monomer of a kind of intensity pillar pole.
Concrete scheme of the present invention is: a kind of transmission line of electricity monomer pillar pole, described monomer pillar pole is by the base that suspends, standard knot and pulley connect to form in turn, the two ends of described standard knot are provided with tapering point joint, described standard knot and end joint are made up of multiple pipe joint bodies, between adjacent segments body, connect by flange, described flange comprises that sidewall establishes reeded core pipe and be arranged on the built-in plate of tubulose at described core pipe top, in described groove, be along the circumferential direction provided with bolt hole, between described built-in plate and described core pipe, be provided with boss, it is bonding integral by glue outward that described joint body is set in described built-in plate, the end of described joint body and described boss offset.
Adopt technique scheme, technique effect of the present invention has:
Pole in the present invention has adopted pipe as main material, and integrated member adopts assembling design, and multiple standard knot connects by flange, requires design various criterion mould according to lifting capacity, is convenient to realize mass production, facilitates processing and manufacturing; The present invention adopts software ANSYS element of construction optimal design, has reduced pole sectional dimension and weight, is convenient to mountain area transport and uses; In pole design, adopt inner flange connected mode, the external diameter of flange is less than the external diameter of standard knot, when pole is promoted, there is no projection obstacle, promotes smooth and easy.
