Abstract
The invention discloses an iron angle tower of a power transmission line, belonging to iron angle towers. The iron angle tower structurally comprises a tower body and a tower leg, wherein a ground wire bracket, an upper wire cross arm, a middle wire cross arm and a lower wire cross arm are sequentially arranged on the tower body; the middle wire cross arm is slightly longer than the upper wire cross arm and the lower wire cross arm; the tower body is formed by lapping a plurality of sections of gradient-change tower sections; the tower body comprises tower columns, a diagonal rod and a cross rod; the cross section of the tower body is quadrilateral, wherein four tower columns are respectively arranged at corners of the quadrangle; and the tower columns are connected with the cross rod and the diagonal rod through connecting plate bolts. Compared with the prior art, the iron angle tower of the power transmission line, disclosed by the invention, has the characteristics of rich and attractive shapes of the tower body, convenience for transportation and installation, good windproof effect, good rigidity, inexistence of potential safety hazards, and the like, thereby having favorable popularization and application values.
Description
Technical field
The present invention relates to a kind of angle steel tower, especially a kind of angle steel tower of power transmission line.
Background technology
Along with the development of China's electric utility is advanced by leaps and bounds, angle steel tower of power transmission line is used comparatively widely, but present employed triangle head tower, also exist following deficiency: because the integral type tower body structure of the slopes such as employing, profile is single, and is stiff, in addition, appearance and size is larger, can not dismantle, transportation, installation inconvenience, protection effect is poor, there is potential safety hazard in poor rigidity.At present, good solution is not also arranged.
Summary of the invention
Technical assignment of the present invention is to provide a kind of angle steel tower of power transmission line for above-mentioned deficiency of the prior art, this angle steel tower of power transmission line have the body of the tower moulding enrich attractive in appearance, transportation, easy for installation, protection effect is good, there are not the characteristics of potential safety hazard in good rigidly.
The technical solution adopted for the present invention to solve the technical problems is: it comprises body of the tower and tower leg, be disposed with earth wire support, upper conductor cross-arm, middle wire cross-arm and lower wire cross-arm on the described body of the tower, described middle wire cross-arm slightly is longer than upper conductor cross-arm and lower wire cross-arm, described body of the tower is that the tower section overlap joint on multistage change slope forms, described body of the tower comprises king-post, brace and cross bar, the cross section of described body of the tower is quadrangle, wherein four king-posts lay respectively at tetragonal bight, and described king-post is connected by the junction plate bolt with cross bar, brace.
Inboard and the outside that the multistage of described composition body of the tower becomes the tower section lap-joint on slope arrange respectively lateral overlap spare and inboard bridge piece, described lateral overlap spare comprises two square plates, described inboard bridge piece is one " L " shape steel plate, and described inboard bridge piece and lateral overlap spare and body of the tower are bolted.
Angle steel tower of power transmission line of the present invention is compared with existing technology, have following outstanding beneficial effect: body of the tower is that the tower section overlap joint on multistage change slope forms, the body of the tower moulding is enriched attractive in appearance, easily dismounting, transportation, easy for installation, protection effect is good, good rigidly, there is not potential safety hazard, uses the characteristics such as safety.
