长期以来，作为提升设备用的卷筒绳槽设计，一般都是采用等角螺旋线形式。随着提升载荷的不断增大，对提升钢绳的定位提出了更高的要求，出现了以折线绳槽取代等角度螺旋槽的新结构形式，它成功 的解决了提升钢丝绳多层缠绕易发生事故的难题。但是其制造困难，应用不广泛。我们 For a long time, as the promotion of equipment used rope groove design, are generally used isotropic spiral form. With the increase of hoisting load, higher requirements are put forward to enhance the positioning of steel ropes. A new structure of replacing equal-angle helical grooves with broken line ropes has emerged, which successfully solves the problem that multi-layer winding of hoisting ropes is easy to occur Accident problems. However, its manufacturing difficulties, the application is not widespread. we
