The invention belongs to the field of lifting mechanisms, and particularly relates to a novel rope disorder prevention winding drum and a hoisting mechanism. The novel rope disorder prevention winding drum comprises a winding drum body, a first flange plate and a second flange plate, a plurality of connected double-folded rope grooves are formed in the circumferential surface of the winding drum body, each double-folded rope groove comprises a first linear rope groove, a first spiral rope groove, a second linear rope groove and a second spiral rope groove which are connected in sequence, a rope outlet is formed in the position, close to the first flange plate, of the winding drum body, and the rope outlet is located between the first linear rope groove and the second spiral rope groove; the layer-changing step comprises a rope climbing step and a rope groove step, the rope climbing step is used for transiting the steel wire rope from the nth layer to the (n + 1) th layer, the rope groove step is used for stably winding the steel wire rope on the (n + 1) th layer, and n is a positive integer. According to the technical scheme, the winding drum is provided with the layer changing step and the reversing boss structure, and the problem of rope disorder caused by large layer changing and reversing deviation when the steel wire rope is freely wound is solved.
本发明属于提升机构领域,具体涉及一种新型防乱绳卷筒及卷扬机构,新型防乱绳卷筒包括卷筒本体以及分别设在卷筒本体两侧端部的第一法兰板和第二法兰板;卷筒本体的圆周面上设有多个相连的双折线绳槽,双折线绳槽包括依次连接的第一直线绳槽、第一螺旋绳槽、第二直线绳槽和第二螺旋绳槽,卷筒本体上靠近第一法兰板处设有出绳口,且出绳口位于第一直线绳槽与第二螺旋绳槽之间;还包括换层台阶和换向凸台,换层台阶包括将钢丝绳由第n层过渡到第n+1层的爬绳台阶以及将钢丝绳稳定缠绕在第n+1层的绳槽台阶,其中,n为正整数。通过本技术方案的实施,卷筒自带换层台阶和换向凸台结构,避免了钢丝绳自由缠绕时易出现换层和换向偏差较大所导致的乱绳问题。
