Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
The embodiment of type is described in further detail.
Referring to Fig. 3 to Fig. 5, the utility model embodiment provides a kind of transposition tower body electric power pylon, and the electric power pylon includes
Along tower head 1, transposition section 2, tower body 3 and the tower leg 4 being longitudinally sequentially connected with.Wherein transposition section 2 is arranged on tower head 1 and tower body 3
Between, transposition section 2 have connection tower head 1 on every under face 21 and connection tower body 3 every face 22, on every face 21 pass through connection component
24 are connected with every face 22, and on every face 21 with every face 22 be quadrilateral structure；Changed, made by the connection of transposition section 2
Tower body 3 is obtained with respect to tower head 1 with predetermined angle transposition.
Realize the relative tower head 1 of tower body 3 with predetermined angle transposition, it is necessary to which explanation is on transposition section 2：On in transposition section 2
There is the transposition of certain predetermined angle with every face 21 every face 22 under conditions of keeping relatively parallel.Specifically, this is pre-
If angle cause under every the parallel side of a quadrilateral structure with every face 21 is not present in the quadrilateral structure in face 22.With
Original state be on every face 21 quadrangle summit with every the quadrangle summit in face 22 it is corresponding exemplified by, with predetermined angle
After transposition, on be staggered every the quadrangle summit in face 21 with every the summit of the quadrangle of face 22.
On this basis, the electric power pylon that the utility model embodiment is provided tower head 1 and company of transposition section 2 when building
Connect, the connection of tower body 3 and transposition section 2, and the connection of tower body 3 and tower leg 4 is same as the prior art.It is therefore to be understood that
Be, in the transposition section 2 every face 21 and under between face 22 tower body 3 and tower head 1 are converted into the technical characterstic of predetermined angle transposition
Between the transposition of predetermined angle be present.
To sum up, occur between the utility model embodiment passes through the electric power pylon of transposition section 2 tower head 1 and tower leg 4
Reverse, when running into abrupt slope during layout of roads, can realize under conditions of keeping transmission line of electricity to move towards constant, pass through
Transposition tower leg 4 evades inferior position landform.Referring in particular to Fig. 6-1, Fig. 6-2, when meeting with slope, because tower leg 4 is with respect to the appearance of tower head 2
When reversing, therefore building electric power pylon, D legs 44 can be separately positioned on the both sides of steep bank with A legs 41.Especially by with Fig. 4-1
Contrasted, be not difficult to find out with the prior art shown in Fig. 4-2, the utility model embodiment proposes the transposition tower body transmission of electricity of arch
Steel tower does not change transmission line of electricity direction, and the torsion of tower leg 4 is only realized by transposition section 2 so that still can in extreme terrain
To carry out electric power pylon construction, adaptability of the tower leg 4 to landform is improved.Simultaneously in comparison diagram 6-1 and Fig. 4-1 earth's surface 7 with
The difference in height of basal plane 8 is understood, poor due to having evaded larger geopotentia when carrying out steel tower construction, can the column foot of effectively reduction open
Side, is effectively protected mountain area natural environment, while is closing at the tower leg 4 on abrupt slope, can also strengthen tower leg by using pile foundation 6
4 stability.
Site select scope is more when the transposition tower body electric power pylon that the utility model embodiment is provided causes line location
Greatly, it is more flexible, effectively it can optimize and shorten transmission line of electricity path, save transmission line of electricity cost, reduce column foot evolution, and subtract
Gently to the destruction of mountain area natural environment, the techno-economic policy of " resource-conserving, environmentally friendly " of engineering project is embodied.
On wherein every face 21, under every face 22 can be rectangle, square；The predetermined angle that transposition section is realized is according to reality
Situation is set, generally 30 °~60 °.
Further, the structure on transposition section 2, reference picture 5, on every face 21 with every face 22 be square, tower
45 ° of angles between first 1 cross-arm direction and adjacent tower leg line be present.Now, under each summit in face 21 has corresponded to every
The wherein a line of the square structure of face 22, connection component 24 by by every the summit in face 21 and its corresponding under every face 22
Side end points connection, in realizations every face 21 and under every face 22 fixation.Simultaneously in order to meet the structural stability of transposition section 2,
On every face 21 and under stiffener assembly 23 is additionally provided between face 22, and do not limited on the concrete form of the stiffener assembly 23
It is fixed, it can be designed according to actual conditions.
On the architecture basics of above-mentioned transposition section 2, the tower head 1 of the electric power pylon provided for the utility model embodiment
Structure is not particularly limited, and can be the dry font tangent tower of wineglass tower, the cat-head transmission tower of wire triangle arrangement or bipolar conductor.
Wherein by taking wineglass tower as an example, reference picture 3, Fig. 4-1 and Fig. 4-2, the tower head 2 include what is be connected with every face 21
A pair of lower bent levers 15, it is connected with lower bent lever 15 cranks arm 14 respectively, is arranged on the cross-arm cranked arm on two on 14, including middle horizontal stroke
Load 13 and the side cross-arm 12 positioned at the middle both sides of cross-arm 13, earth wire support 11 is connected on cross-arm.Wherein the direction of cross-arm with it is right
The line of tower leg 4 that angle is set is parallel, i.e. now 45 ° of the relative line direction transposition of tower leg 4.
The transposition tower body electric power pylon that the utility model embodiment is provided realizes tower body 3, tower leg 4 by transposition section 2
With respect to the torsion of tower head 1, fitness of the tower leg 4 to landform is improved, for shortening transmission line of electricity, optimization circuit provides technology
Support, and effectively reduce manual operation amount and the destruction to environment.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
