Abstract
Provided is a novel electric transmission line tower. The lower end of a composite material tower body upper section of a left component and the lower end of a composite material tower body upper section of a right component are connected with the upper end of a tower body lower section of the left component and the upper end of a tower body lower section of the right component through flanges and connecting bolts. The composite material tower body upper section of the left component and the composite material tower body upper section of the right component are connected in a crossing mode through supporting rods, and oblique pulling rods are connected between the supporting rods and the composite material tower body upper sections. A left cross arm and a right cross arm are respectively composed of two rods which are parallel, and the two rods are clamped on a composite material tower head to be fixed. Two ends of the left cross arm and two ends of the right cross arm are connected with the top end of the composite material tower head through two oblique pulling rods. The top end of the composite material tower head is connected with a ground wire cross arm in an assembled mode. The novel electric transmission line tower is simple in structure, easy to assemble, long in service life, resistant to corrosion, ageing-resistant and oxidation-resistant. Suspension type insulator chains on an original tower are removed, a transmission line passage way is narrowed, weight is light, maintenance is needless, line manufacturing cost is lowered, and operating cost is saved.
Description
Technical field
The utility model relates to a kind of overhead transmission line line pole tower, and a kind of novel electric power line pole tower particularly is applicable to circuit crowd location, city and development zone, suburbs, other special circuit and special location.
Background technology
National network has appearred in the development along with electrical network, transferring electricity from the west to the east, the mutual power supply network in north and south is built general layout, work transmission line is more and more, and is also increasing to the demand of steel, and overhead line structures adopt full steel structure, owing to adopt insulator in the structure, not only tower body height, and tower head size is big, processes loaded down with trivial details, transportation and assembly cost height cause width of corridor wide.There are heavy, the problems such as transportation and operation maintenance difficulty of constructing of quality.
The utility model content
The purpose of this utility model provides a kind of novel electric power line pole tower, reduces the size of tower head, and the cancellation insulator reduces tower height, reduces width of corridor, increases the service life, and the reduction expense improves the reliability of safe operation.
The utility model provides following technical scheme: left and right assembly is set, left and right assembly has included composite material tower head, cross-arm, composite material body of the tower epimere, body of the tower hypomere, it is characterized in that: composite material body of the tower epimere lower end is connected with connecting bolt by flange with the upper end of body of the tower hypomere; Be connected diagonal member between the interconnection support bar between the composite material body of the tower epimere of left and right assembly, support bar and composite material body of the tower epimere; Left and right cross-arm constitutes by two bars arranged side by side, and two bars support the composite material tower head, and fixes by securing member; The two ends of left and right cross-arm all are connected by the diclinic pull bar with composite material tower head top; Composite material tower head top assembling connects the ground wire cross-arm, is connected support bar between ground wire cross-arm and the tower head.
Good effect of the present utility model is: reduced the size of tower head, cancelled insulator, reduced tower height and reduce width of corridor, increased the service life, the reduction expense improves the reliability of safe operation.
