Abstract
The utility model discloses a four-pipe tower for a power transmission line and belongs to four-pipe towers. The four-pipe tower comprises a tower body and tower legs; the tower body is provided with a ground wire support, an upper conducting wire cross arm, a middle conducting wire cross arm and a lower conducting wire cross arm sequentially; the middle conducting wire cross arm is slightly longer than the upper conducting wire cross arm and the lower conducting wire cross arm; the tower body comprises tower columns, inclined rods and horizontal rods; the section of the tower body is quadrilateral; four tower columns are positioned at the corners of the quadrilateral section; the tower columns are steel pipes; the circumferential surface of the tower column is welded with connection plates; the horizontal rods and the inclined rods are in threaded connection with the tower columns through the connection plates; the tower plate is formed by connecting a plurality of tower sections with gradient change; two ends of each tower section are welded with flange plates; and the tower sections are fixed through the flange plates. The four-pipe tow for the power transmission line has the advantages that: the model of the tower body is full and attractive, is convenient to transport and install, and has a good wind resistance effect and high rigidity; and potential safety hazard is avoided and the like, so that the four-pipe tower has good popularization and application value.
Description
Technical field
The utility model 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 exist 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, there is potential safety hazard in poor rigidity.At present, good solution is not also arranged.
The utility model content
Technical assignment of the present utility model is to provide a kind of transmission line of electricity four pipe towers at above-mentioned deficiency of the prior art, this 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 scheme that its technical problem that solves the utility model adopts is: it comprises body of the tower and tower leg, be disposed with the ground line bracket on the described body of the tower, the upper conductor cross-arm, middle lead cross-arm and lower wire cross-arm, the lead cross-arm slightly is longer than upper conductor cross-arm and lower wire cross-arm in described, 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, described king-post is a steel pipe, described king-post is welded with junction plate on periphery, described cross bar is connected with the king-post bolt by junction plate with brace, described body of the tower is that the tower section on multistage change slope is formed by connecting, the two ends of every section tower section all are welded with flange, fix by 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 utility model 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 by flange, 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.
