“大节距扭绞型钢索的制造方法和设备”发明专利是制造新型桥梁用钢索的关键生产技术。它能将数百根φ5mm或φ7mm 的高强度钢丝一次同心、同向绞合成断面为六边形(或缺角六边形)的钢索,绞合、成形、包带三工序能连续一次完成。用本技术制作的挤包护层扭绞型钢索具有优良的机械性能和防护性能,并能弯曲成盘,实现工厂化生产,施工、运输十分方便。本发明对钢索传统生产工艺和
“Method and Equipment for Manufacturing Large Pitch Twisted Ropes ” The invention patent is the key production technology for manufacturing new type of steel cables for bridges. It can be hundreds of φ5mm or φ7mm high-strength steel wire once concentric, twisted together into a hexagonal section (or missing hexagonal) of the cable, stranding, forming, with three steps to complete a package . The extruded sheath twisted steel cable produced by the technology has excellent mechanical performance and protective performance, and can be bent into a plate to realize industrialized production, construction and transportation with great convenience. The invention of the traditional production technology and cable
