Description
Technical field
The present invention relates to a kind of selection method of steel tube tower steel tube component, particularly relate to a kind of selection method of UHV transmission steel tube tower steel tube component.
Background technology
Along with transmission line of electricity transmission capacity and electric pressure improve constantly, tower load and tower weight constantly increase; Increase gradually with the application of neck forged flange in extra-high voltage steel tube tower, adopt forged flange connection can reduce welding job amount, stablize crudy, improve work efficiency; Analyze present extra-high voltage steel tube tower operation drawing, the densimetric analysis that selected part supervisor typical case carries out forged flange is known: (1) forged flange weight (body and bolt) accounts for the proportion of whole steel tube component (not considering weld connection plate and stiffener) about 10% ~ 30%; (2) weight due to flange is relatively fixing, so along with the change of component length, flange proportion is also in change, and component is shorter, and flange proportion is larger; (3) same specification steel pipe, with the raising of steel strength, the corresponding increase of proportion of forged flange; In existing method, be only by list in " steel tube tower in electric transmission line tectonic sieving regulation " with the specification of the forged flange standardized size table determination forged flange of steel pipe match specifications, but the proportion accounting for steel tube component due to forged flange is larger, and steel pipe selection method conventional at present ignores the impact of forged flange on steel tube component weight, cause the weight of steel tube component in practical structures (containing forged flange) not reach minimum, cause steel quantity consumption to increase.
Summary of the invention
The object of this invention is to provide a kind of selection method of steel tube tower steel tube component, the inventive method can realize carrying out design and select material together with the forged flange that steel tube component and two ends welds, reduces steel tube tower weight, improves the economy of steel tube tower structure.
Concrete scheme of the present invention is: a kind of selection method of UHV transmission steel tube tower steel tube component, the bolt that described steel tube component comprises steel pipe, is welded on the forged flange body at described steel pipe two ends and is connected with described flange body, the selection method of described steel tube component is:

Fig. 3 is the structural representation of forged flange body in steel tube component of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, a kind of selection method of UHV transmission steel tube tower steel tube component, the bolt 3 that described steel tube component comprises steel pipe 1, is welded on the forged flange body 2 at described steel pipe two ends and is connected with described flange body, the selection method of described steel tube component is:

C
f, C
nthe cost ratio coefficient of-forged flange body and bolt and steel pipe.
The weight of described steel tube component is described steel pipe weight, this body weight of forged flange at described two ends and the described bolt weight sum of 1/2nd quantity.
Another preferred embodiment of the present invention is, when the forged flange body specification at described steel pipe two ends is identical, the selection method of described steel tube component is:
W＝W
p+2W
F1C
F+W
N1C

Another preferred embodiment of the present invention is, when the present invention is best for preferred version with weight, in the selection method of described steel tube component, and described cost ratio coefficient C
f, C
nbe 1.
Another preferred embodiment of the present invention is, when the present invention is best for preferred version with cost, in the selection method of described steel tube component, determines the relative ratio C of each manufacture cost of parts according to market conditions
f, C
n, such as contemporaneity steel pipe cost is 8000 yuan/ton, and forged flange is 15000 yuan/ton, and bolt is 10000 yuan/ton, then C
f=15000/8000=1.875, C
n=10000/8000=1.25.
Another preferred embodiment of the present invention is, described forged flange body 2 is hubbed flange.
Consider that flange weight is on the impact of selection to illustrate, spy tests, the axial compression supporting capacity of single steel tube component is not less than 7500kN, material is Q345, and carry out selection by the steel pipe specification storehouse in " steel tube tower in electric transmission line tectonic sieving specifies ", consider flange weight when being divided into conventional design (not considering flange) and selection and consider flange cost three kinds of selection situations, steel tube component length range is 5m ~ 9m, and concrete result of the test sees the following form.
Consider flange weight in table and consider that the ratio of two schemes of flange cost is the ratio with conventional design numerical value, "/" represents and not to change by specification after the inventive method selection.As seen from the above table, when considering the two schemes of flange weight and consideration flange cost influence, although increase relative to conventional design steel pipe weight, flange weight significantly reduces, and steel tube component overall weight is reduced, and cost decreases.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, although with reference to above-described embodiment to invention has been detailed description, those of ordinary skill in the field are to be understood that: still can modify to the specific embodiment of the present invention or equivalent replacement, and not departing from any amendment of spirit and scope of the invention or equivalent replacement, it all should be encompassed in the middle of right of the present invention.
