Abstract
The present invention is related to a system and method for manufacturing steel tapered poles from previously cut and punched steel strips, which are arranged together on a mold and subsequently welding the steel strips on place as to form a substantially one piece tapered pole.
Claims2
A system for manufacturing steel tapered poles from previously cut and punched steel strips, comprising:
- a welding device (A) and a pole mold (B) located one in front of the other for operative interaction, for forming a steel pole on the mold from steel strips and welding together the steel strips;
- the welding device (A) comprises a welding wire (2), a welding carriage (3) and a submerged arc welder (11);
- The welding device (A) device is slideably mounted on a submerged arc welding beam (1) to weld strips of steel together where needed;
- in front of the welding device (A) there is located a pole mold (B) comprising a mold pipe (12), rotatable supported by a bearing (10) placed over a mold support (7) vertically extending upwards from a base (8);
- the mold pipe (12) holds a plurality of mold plates (4) distributed through out the length of the mold pipe.
2 more elements
a method for manufacturing steel tapered poles from previously cut and punched steel strips, comprising the steps of:
- cutting steel strips (6) with plasma, into a trapezoidal shape;
- punching the strips (6) as to make holding holes 14;
- placing the previously cut and punched steel strips (6) over a mold (B) by means of a hoist (13);
- arranging the steel strips (6) over the mold in such a form that the holding holes (14) are fit on upwardly projecting bolts (5) located in the front faces of mold plates (4) of the mold (B) to hold the steel strips (6) in their correct position for welding;
- align all the steel strips (6) on the mold by means of adjustable supports (9);
- fastening the steel strips (6) into place with the bolts (5);
- welding together the steel strips (6) using a submerged arc welder (11) by rotating the mold sequentially;
- removing the bolts (5) from the mold;
- extracting the so formed steel tapered pole from the mold utilizing an hydraulic extractor.
