Abstract
The present invention relates to the improvement on an electric power iron tower, which comprises pillars, supporting rods, drawing wires and cross arms. The present invention is characterized in that tower legs are composed of main pillars 1 and short pillars 3, the top of the short pillar 3 is connected with the main pillar 1 via a horizontal bar 5, and the drawing wires are arranged between the main pillars and the short pillars. A horizontal strut 4 is arranged between the tops of two short pillars 3. The present invention has the advantages of low steel consumption and ground occupancy, no damage of the drawing wires in the iron tower contour, standardized production of most of components, good anti-theft performance and small acting force to base from the iron tower.
Description
The present invention relates to the overhead transmission line iron tower, belong to transmission facility.
Traditional iron tower of power transmission line mainly contains self-supporting tower and stayed tower.Self-supporting tower is less because of its occupation of land, body of the tower intensity height, and advantage such as be difficult for toppling adopted widely, but its steel consumption amount is higher, and the tower material is stolen easily.The stayed tower steel consumption is lower, and cost is lower, but its floor space is bigger, and it is outer and not obvious that backguy is exposed to body of the tower, so be damaged easily and cause the accident of falling the tower.
The iron tower that the purpose of this invention is to provide a kind of new structure makes it have the advantage of above two kinds of iron towers concurrently.
Electric power pylon provided by the present invention comprises column, strut, and backguy and cross-arm is characterized in that: the iron tower tower leg is made up of head tree and short column, and the top of short column connects firmly through horizon bar and head tree, is provided with backguy between head tree and short column.
The quantity of head tree is selected two for use, makes its installation site on the long axis of cross-arm, preferred two and its axial line is overlapped with the minor axis of cross-arm of the quantity of short column.
Preferred scheme is divided into two parts up and down with backguy, and an end of last main drawing line is positioned at the junction of cross-arm and head tree, and the other end is positioned at the top of short column, and an end of following main drawing line is positioned at the top of short column, and the other end is positioned on the bottom or basis of head tree.
In order to prevent that the prismatic framework that horizon bar is formed is out of shape because of stressed, the present invention is provided with triatic stay between two relative short columns.
In order to reduce the slenderness ratio of head tree, make it can bear bigger pressure, perhaps satisfy lighter weight designing requirement, the present invention is provided with at least two group auxiliary rods on head tree.
In order to increase the bulk strength of body of the tower, the present invention is provided with auxiliary stay between the top of auxiliary rod between the top of head tree and auxiliary rod and on the same group.
The present invention considers from the aspect of structure optimization to select steel pipe to make head tree, and short column, strut and horizon bar make it to have the alternative advantage such as strong of the little and specification of structure blast.
Advantage of the present invention is: 1, reduce steel consumption 10～25% than self-supporting tower, reduce investment outlay 11～18%; 2, most of member can standardized production, helps ensuring the quality of products, reducing manufacturing cost; 3, the member theftproof performance is good, and antitheft, anti-handler need be set specially; 4, the shaft tower parts are few, and construction, the installing engineering amount is little, can accelerate construction, installation rate, reduces operating expenses; 5, basic role power reduces, and stress condition improves, and therefore can reduce foundation cost; 6, because backguy partly is connected with the body of the tower self-support, backguy all within the outline line of iron tower, so be difficult for being damaged, has improved the application life and the safety in utilization of body of the tower.
Introduce embodiment of the present invention below in conjunction with Figure of description:
Figure of description 1 is an agent structure schematic diagram of the present invention;
Figure of description 2 is left side views of accompanying drawing 1;
Figure of description 3 is vertical views of accompanying drawing 1.
In above-mentioned accompanying drawing 1---head tree, 2------short column, 4---triatic stay of going up main drawing line, 3,5---horizon bar, 6---auxiliary rod, 7---cross-arm, 8---following main drawing line, 9---auxiliary stay.
As shown in the figure: the present invention supports conventional cross-arm 7 with two steel pipe system head trees 1, and lead and lightning conducter are fixed on the cross-arm 7 in the usual way.Short column 3 is also made with steel pipe, and short column 3 is selected two usually for use, constitutes the tower leg of iron tower jointly with head tree.The layout of tower leg is compared with traditional iron tower and has been rotated miter angle, promptly the cross-arm 7 with iron tower is an object of reference, the installation site of two head trees 1 should make the long axis of its line and cross-arm 7 coincide, and the line of two short columns 3 is vertical with the line of two head trees 1, and itself and cross-arm 7 minor axis are coincided.Four horizon bars 5 join with an end and short column 3 separately, and the other end and head tree 1 join, and form a prismatic from vertical view.Triatic stay 4 its two ends lay respectively at the intersection of horizon bar 5 and short column 3 to increase the intensity of body of the tower.Last main drawing line 2 is pulled in from the head tree 1 and the junction of cross-arm 7 on the prismatic be made up of four horizon bars 5 and two angles that short column 3 is connected, and the prismatic that following main drawing line 8 is formed from horizon bar 5 and short column 3 two crossing angles are pulled on the bottom or basis of head tree 1.The starting point at the radical of main drawing line and two ends should be done corresponding adjustment when the body of the tower height change, and particular location design and calculation method is routinely determined.The bottom of head tree 1 and short column 3 is connected with the basis.When being subjected to vertical force, mainly bear by two head trees 1.When being subjected to lateral force to do the time spent, main drawing line is subjected to pulling force, and head tree 1 is stressed.Be subjected to pulling force when being subjected to vertical body to make the time spent main drawing line, head tree 1 is stressed, and a short column 3 is stressed, and the short column 3 of another root is subjected to pulling force.
In order to reduce the slenderness ratio of head tree 1, make it can bear bigger pressure or make it lighter, can add an above auxiliary rod 6, accompanying drawing 1 is depicted as bilevel structural form, and every layer has one group of auxiliary rod 6.One end and the head tree 1 of auxiliary rod 6 connect firmly, and the other end links to each other with head tree 1 or/and other auxiliary rods through auxiliary stay 9.
