Description

Technical Field

[0001] This utility model belongs to the field of steel pipe bundling, and in particular relates to a steel pipe bundling device. Background Technology

[0002] Steel pipes are steel materials with hollow cross-sections, whose length is much greater than their diameter or circumference. They are classified by cross-sectional shape into round, square, rectangular, and irregularly shaped steel pipes; by material into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes, and composite steel pipes; by application into pipes for transportation, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, and high-pressure equipment; and by manufacturing process into seamless steel pipes and welded steel pipes. Seamless steel pipes are further divided into hot-rolled and cold-rolled (drawn) types, while welded steel pipes are divided into straight-seam welded steel pipes and spiral-seam welded steel pipes.

[0003] Currently, when bundling square or rectangular steel pipes, multiple pipes need to be stacked into the required rectangular structure. Then, steel straps are applied to the outside of the rectangular structure. Workers need to bend the straps to fit the outside of the rectangular structure by hammering or other means. Finally, the strap joints are fastened or welded. The bundling process is complicated and labor-intensive. Summary of the Invention

[0004] In view of this, the present invention aims to provide a steel pipe bundling device to solve the problems of inconvenient manual operation and high labor intensity when bundling steel pipes with steel straps in the prior art.
