At present, various domestic seamless steel pipe companies have put forward new requirements for yield strength and tensile strength for the high strength and toughness performance requirements of pipe fittings. High-strength quenched and tempered seamless steel pipe (Q890), high-strength cold-formed seamless steel pipe is mainly used in such fields as hydraulic crawler crane combined boom pipe, hydraulic cylinder pipe, bridge structure pipe, offshore platform structure and other fields.

High-strength cold-formed seamless steel pipe is a kind of seamless steel pipe with high dimensional accuracy and good surface finish for precision mechanical structures, hydraulic equipment or steel sleeves. In the process of transferring the steel pipe, the form of binding is generally adopted, that is, the steel pipe is bound by a steel belt into a steel pipe bundle with a regular hexagonal cross-section. This regular hexagonal binding method is solid and stable, which is convenient for the transfer of the steel pipe. There is no special auxiliary equipment in the lashing process, and the lashing of steel pipes is time-consuming and labor-intensive.

For this reason, those skilled in the relevant technical field have made improvements, for example, the Chinese Patent Application No. CN201420030359.9 proposed "A cold-rolled seamless steel pipe binding auxiliary device, which is characterized in that it includes a base plate, and the base plate is fixed on the base plate. A bottom plate is installed, the two ends of the bottom plate are hinged to the side plates through the hinge shaft, the side plate has an inward angle of 120°, and the inner edge of the bottom plate and the inner edges of the two side plates form a regular hexagon.
