Abstract
The utility model relates to a barrel section type steel pipe pole, in particular to a steel pipe pole for a power transmission line. In the high voltage grade transmission line, the diameter of the steel pipe is generally designed into 3 m, 4 m or above; because a gap exists in the matching position of the flange of the steel pipe pole, the inner part of the pole body is of an open structure, is not preservative generally, and can generate the oxidation and the rustiness after being used for a period of time, thereby reducing the strength of the steel pipe pole and influencing the service life of the steel pipe pole. The barrel section type steel pipe pole comprises the pole body and the flange, and is characterized in that the pole body is formed by connecting more than two hollow cone-shaped pole sections through the connection flanges; a locking plug is arranged at the top part of the pole body; and a solid reinforced rib plate with the shape matched with that of the internal section of the pole sections is arranged inside the pole body. The utility model has the advantages that the oxidation and the rustiness inside the pole body can be prevented, the service life is prolonged, and the cost is saved.
Description
Technical field
The utility model relates to a kind of electric power transmission line steel pipe pole, relates in particular to shell ring formula steel pipe pole.
Background technology
The electric power transmission line steel pipe pole is a kind of equipment supporter that is widely used in the urban and rural power grids transmission line of electricity, compare with like product (cement pole, angle steel tower etc.), it is with good looking appearance, in light weight, floor space is little, durable in use, can satisfy the load needs of multiloop large-section lead and angle pole and not establish the requirement of strength of backguy and used in a large number.Along with the sustained and rapid development of national economy, increasing to the demand of electric power, especially at present on the occasion of the peak period of urban network restructuring, the market demand of transmission line of electricity steel pipe pole day by day increases, and will continue to have an optimistic view of in the market in future.
The steel pipe pole of Shi Yonging is to make the circle or the polygon body of rod with certain taper by roll of steel plate in the market.In the voltage levels transmission line of electricity, especially in 500 kilovolts and 750 KVs, in order to satisfy the needs of big load, the diameter of steel pipe pole to be designed to usually 3 meters, 4 meters or more than, otherwise be subjected to the wind-force effect easily and bending.Because there is the gap in steel pipe pole flange cooperation place, body of rod inside is Open architecture, and body of rod inside is not anticorrosion usually, and oxidation and rusting will take place in body of rod inside behind the use certain hour, reduces the intensity of steel pipe pole, influences its application life.
The utility model content
The purpose of this utility model is to provide a kind of can prevent that the body of rod internal oxidation from getting rusty, and prolongs its application life, reduces body of rod diameter as far as possible under the prerequisite that guarantees the steel pipe pole structural strength, saves the shell ring formula steel pipe pole of cost.
The technical scheme that realizes above-mentioned purpose is:
Shell ring formula steel pipe pole comprises the body of rod and flange, it is characterized in that the body of rod is formed by connecting through adpting flange by the above conical hollow bar section of two joints, and the top of the body of rod is provided with plug, described bar intersegmental part be provided with the bar section in the solid reinforcement gusset that matches of cross sectional shape.
Described adpting flange divides upper flange and lower flange, and one of them flange is the circular hollow circulus, and another is the circular solids structure.Solid construction is used to seal shell ring, and hollow-core construction has been saved cost owing to use the booster action of solid construction little at same position with hollow-core construction.
Described upper and lower flange connects by bolt.
The cross section of the described body of rod is annular or polygon annular.
Flange of the described end is the circular solids structure.
The beneficial effects of the utility model are:
1, the utility model shell ring formula steel pipe pole is forming closed cavity between gusset and the gusset and between gusset and the solid flange, the top of steel pipe pole is sealed with plug, prevents entering of air and rainwater, and the body of rod can oxidation and rusting, be difficult for being corroded, prolonged the application life of steel pipe pole.
2, the utility model shell ring formula steel pipe pole reasonable in design reduces body of rod diameter as far as possible under the prerequisite that guarantees the steel pipe pole structural strength, saved cost.
