Abstract
The invention discloses a four-pipe tower of a power transmission line, belonging to four-pipe towers. The four-pipe 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 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, the tower columns are made of steel pipes, and a connecting plate is welded on the circumferential surface of each tower column; the cross rod and the diagonal rod are in bolted connection with the tower columns through a connecting plate; the tower body is formed by connecting a plurality of sections of gradient-change tower sections; and flange plates are respectively welded at two ends of each section of tower section, and the tower sections are fixed through the flange plates. Compared with the prior art, the four-pipe 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 iron tower, especially a kind of transmission line of electricity four pipe towers.
Background technology
Along with the development of China's electric utility is advanced by leaps and bounds, transmission line of electricity angle steel tower is used comparatively widely, but present employed triangle head tower also exists following deficiency: because the integral type body of the tower structure of slopes such as employing; Profile is single, and is stiff, in addition; Appearance and size is bigger, can not dismantle transportation, installation inconvenience; Protection effect is poor, and 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 transmission line of electricity four pipe towers to above-mentioned deficiency of the prior art, these transmission line of electricity four pipe towers 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 ground line bracket, upper conductor cross-arm, middle lead cross-arm and lower wire cross-arm on the described body of the tower, described middle lead cross-arm slightly is longer than upper conductor cross-arm and lower wire cross-arm, and described body of the tower comprises king-post, brace and cross bar; The cross section of described body of the tower is a quadrangle; Wherein four king-posts lay respectively at tetragonal bight, and described king-post is a steel pipe, and described king-post is welded with junction plate on periphery; Described cross bar is connected with the king-post bolt through junction plate with brace; Described body of the tower is that the tower section on multistage change slope is formed by connecting, and the two ends of every section tower section all are welded with flange, fix through flange between the tower section.
Be provided with a plurality of stiffened panels between described flange and the body of the tower, described a plurality of stiffened panels evenly distribute along the flange circumference.
Transmission line of electricity four pipe towers of the present invention are compared with prior art, have following outstanding beneficial effect: body of the tower is that the tower section on multistage change slope is fixedly connected through flange, and the body of the tower moulding is enriched attractive in appearance; Dismounting easily; Transportation, easy for installation, protection effect is good, good rigidly; There is not potential safety hazard, characteristics such as safe in utilization.
