The diameter-variable rope changing guide device comprises a fan-shaped follow-up guide unit, the fan-shaped follow-up guide unit comprises a fan-shaped sleeve frame and a chain transmission conveying assembly, the fan-shaped sleeve frame comprises fan-shaped vertical plates which are arranged in a bilateral symmetry mode, and the central angle of each fan-shaped vertical plate is not smaller than 90 degrees; the chain transmission conveying assembly at least comprises two chain wheels and a bearing chain connected to the two driven chain wheels in a matched mode, a bearing body matched with the arc face of the outer diameter of the steel wire rope is arranged on a chain link of the bearing chain, and the driven chain wheels are installed between the two fan-shaped vertical plates in a rolling fit mode. The central angles, corresponding to the fan-shaped vertical plates, of the two driven chain wheels are located on the two radius lines, passing through the circle center, of the fan-shaped vertical plates respectively, the driven chain wheels are installed on the fan-shaped vertical plates through driven chain wheel position adjusting mechanisms, and bearing chain supporting components are further arranged at the positions, corresponding to the arc sections of the fan-shaped vertical plates, between the two fan-shaped vertical plates. According to the invention, guiding and reversing of the steel wire rope with a large minimum bending radius can be realized on the premise of occupying a small installation space.

    本发明公开了一种可变径换绳导向装置,包括扇形随动导向单元,扇形随动导向单元包括扇形套架以及链传动输送组件,扇形套架包括左右对称设置的、圆心角不小于90°的扇形立板,链传动输送组件至少包括两个链轮以及配合连接在两个从动链轮上的承载链,承载链的链节上设有与钢丝绳外径弧面配合的承载体,从动链轮滚动配合安装在两件扇形立板之间,两件从动链轮对应扇形立板的圆心角分别位于扇形立板的两个经过圆心的半径线上、且从动链轮通过从动链轮位置调节机构安装在扇形立板上,两件扇形立板之间对应扇形立板圆弧段的位置还设有承载链支撑部件。本发明可实现在较小的安装空间占用的前提下满足最小弯曲半径较大的钢丝绳的导向换向。
