The invention discloses a pulley anti-falling device of a self-dismounting device. A pulley comprises a wheel, side plates installed on the two sides of the wheel and a rotating shaft fixedly connecting the wheel with the side plates. The wheel is mounted on the rotating shaft through a bearing; a steel wire rope for hoisting is placed on the wheel; anti-falling blocks are respectively mounted on the side plates on the two sides of the wheel; the anti-falling block is of a circular ring fan-shaped structure; and the upper part of the anti-falling block is provided with an oblique angle notch in the same tangential direction as the wheel. The anti-falling blocks are additionally arranged on the two sides of the pulley and correspond to the two sides of the pulley on the pulley structure, smooth and normal work of the pulley is guaranteed, meanwhile, the steel wire rope is prevented from being separated from the pulley groove and moving to the position between the side plate and the pulley to be abraded, and separation and eccentricity between the bearing and the pulley structure possibly caused between gaps are prevented; therefore, the dismounting safety and the dismounting efficiency of the self-dismounting tower crane are improved.
本发明公开了一种自拆装置滑轮防脱装置,滑轮包括轮子,安装在轮子两侧的侧板以及将轮子与侧板固定连接的转轴;所述轮子通过轴承安装在转轴上;所述轮子放置有吊装用的钢丝绳;在所述轮子两侧的侧板上分别安装有防脱块;所述防脱块为圆环扇形结构;所述防脱块上部设有与轮子相同角度切向方向的斜角缺口。本发明在滑轮的两侧增加防脱块设计,防脱块对应滑轮结构上的滑轮两侧,在保证滑轮顺利正常工作的同时,防止钢丝绳脱离滑轮槽,窜动至侧板与滑轮之间磨损,以及在间隙之间可能造成的轴承与滑轮结构之间的脱离和偏心,实现钢丝绳与滑轮的侧面防脱,进而提高自拆塔式起重机的拆卸安全和拆卸效率。
