Abstract
The utility model relates to a single pole elliptic steel pipe iron tower. A tower top is the connection point of an overhead ground wire. Cross arms are symmetrically distributed on the two sides of a single pole steel pipe. Conducting wire suspension points are arranged on the cross arms. The cross section of the single pole steel pipe is elliptical. An angle from 0 DEG to 90 DEG is formed between the direction of the cross arms and the elliptical major axis of the cross section of the single pole steel pipe. The cross section elliptical major axis of the tower always is kept consistent with the direction of the maximum accepting bending force in a transmission line. Materials can be saved and product costs can be decreased under the condition of equal stress demand.
Description
The utility model relates to power equipment, particularly iron tower of power transmission line.
Aerial high-voltage power transmission line generally has angle steel tower, cement electric pole and steel pipe iron tower several.The urban district ultra-high-tension power transmission line generally adopts the steel pipe iron tower at present, because steel pipe iron tower floor space is littler than angle steel tower, than cement pole intensity height, corner is without backguy, help urban beautification, but steel pipe iron tower cost is higher, having influenced it generally applies, as the patent No. is that 92240030 Chinese patent discloses a kind of transmission line of electricity single-column steel pipe iron tower, body of the tower single-column steel pipe cross section is circular, up-thin-low-thick, hollow rolls with steel plate, the bending resistance of its all directions, shearing resistance, antitorque equating, and the steel pipe iron tower in use actual loading be curved to be subjected to, and always have a direction to bear maximal bending moment, the direction vertical with this direction born less moment of flexure, so cross section is circular single-column steel pipe iron tower waste material, can not play one's part to the full.
It is a kind of under equal force request condition that the purpose of this utility model is to provide, and reduces the single-column steel pipe iron tower of former material materials.
Technical solution of the present utility model is: the oval steel pipe iron tower of single-column, cat head is the lightning conducter contact, cross-arm is symmetrically distributed in single-column steel pipe both sides, the lead hitch point is arranged on it, cross-arm is fixedlyed connected with the single-column steel pipe, the cross section of single-column steel pipe is oval, and the cross-arm direction becomes 0～90 ° of angle with the cross section transverse of single-column steel pipe.
According to technique scheme, the cross section transverse of the tangent tower in the transmission line of electricity, angle tower becomes 0 ° of angle with the cross-arm direction, the cross section transverse of terminal tower and cross-arm direction are at an angle of 90, the cross section transverse and the cross-arm direction of terminal angle tower acutangulate, like this in transmission line of electricity, the cross section transverse that remains the single-column steel pipe is with to receive most curved force direction greatly identical, compare with the steel pipe iron tower of circular cross-section, under the situation of bearing same maximal bending moment, the same wall thickness of steel pipe, can shorten perimeter of section, save raw material, reduce the product cost.
Accompanying drawing 1 is the utility model structural representation:
Accompanying drawing 2 is the utility model terminal tower vertical view:
Accompanying drawing 3 is the utility model terminal angle tower vertical view:
Accompanying drawing 4 is the utility model tangent tower vertical view.
In conjunction with the accompanying drawings, embodiment of the present utility model is described, the oval steel pipe iron tower of single-column, cat head is lightning conducter contact [1], cross-arm [4] is symmetrically distributed in single-column steel pipe [2] both sides, lead hitch point [3] is arranged on it, cross-arm [4] is fixedlyed connected with single-column steel pipe [2], and the cross section of single-column steel pipe [2] is oval, and cross-arm [4] direction becomes 0-90 ° of angle with the cross section transverse of single-column steel pipe [2], wherein, terminal tower is 90 ° of angles, and tangent tower is 0 ° of angle, and the terminal angle tower is an acute angle, cross-arm [4] is connected with bolt with single-column steel pipe [2], cross-arm [4] can be designed to several shapes such as circular arc or bending shape, makes its moulding more attractive in appearance, and lightning conducter contact [1] and lead hitch point [3] are by common iron tower setting, it can be connected, column foot flange and stone bolt and basic fixed with the standard gold utensil.
Claims (2)
1, the oval steel pipe iron tower of single-column, cat head is lightning conducter contact [1], and cross-arm [4] is symmetrically distributed in single-column steel pipe [2] both sides, and lead hitch point [3] is arranged on it, cross-arm [4] is fixedlyed connected with single-column steel pipe [2], and the cross section that it is characterized in that single-column steel pipe [2] is for oval.
