The special electric pole for railway power transmission comprises a main pole and a cross arm, wherein the main pole adopts I-steel. The electric pole is characterized in that the main pole is trapezoidal or conical; the width of the upper end of the main pole is less than that of the lower end of the main pole; the section of the cross arm is of a cross shape; one end of the cross arm is fixed with a connecting plate; the connecting plate is fixed with the upper end of the main pole; and the main pole and the cross arm are both made of stainless steel. The electric pole has the characteristics of beautiful appearance and high strength.
Description
Technical field
The utility model relates to a kind of railway electric power transfer electric pole, belongs to electrical equipment technical field.
Background technology
Railway electric power transfer electric pole has concurrent, steel electric pole, and existing steel electric pole adopts i iron mobile jib, tubular type cross-arm, and the tubular type cross-arm is fixedlyed connected with the upper end of i iron mobile jib, fixedlys connected with flange base in the lower end of i iron mobile jib; I iron mobile jib width up and down is the same, not attractive in appearance; Cross-arm adopts steel pipe, and intensity is low.
Summary of the invention
The purpose of this utility model is to provide a kind of railway electric power transfer attractive in appearance, that intensity is high special-purpose electric pole.
To achieve these goals, the technical solution of the utility model is: the special-purpose electric pole of railway electric power transfer, and it comprises mobile jib, cross-arm, mobile jib adopts i iron; It is characterized in that: mobile jib is trapezoidal or taper, and the width of mobile jib upper end is less than the width of its lower end; The cross section of cross-arm is cross, and an end of cross-arm is fixedlyed connected with junction plate, and junction plate is fixedlyed connected with the upper end of mobile jib; The material of mobile jib, cross-arm is stainless steel.
Be fixedly connected with support bar between described junction plate and the cross-arm.
Described mobile jib is provided with the hole.
The beneficial effects of the utility model are: the same up and down width with existing i iron mobile jib is compared, and mobile jib of the present utility model is trapezoidal or taper, and the width of mobile jib upper end is less than the width of its lower end, and is elegant in appearance; Cross-arm adopts cross stainless steel, compares with existing steel pipe, and the intensity height is 3 times of steel pipe.Adopt support bar, cross-arm support strength height.Mobile jib is provided with the hole, saves material, and wind resistance is good.The material of mobile jib, cross-arm is stainless steel, has prevented the pollution of zinc-plating material to environment.
