The invention discloses a rope ejection-proof reinforcing device for an endless rope winch. The rope ejection-proof reinforcing device comprises wheel bodies, wherein inner cavities are formed in thewheel bodies; blocking pieces are mounted at the tops of the wheel bodies; the top diameters of the inner cavities are smaller than the diameters of the blocking pieces; the inner cavities are throughcavities; and the bottom diameters of the inner cavities are larger than the top diameters of the inner cavities. As fixed gaps are formed between the wheel bodies and lug type plate rotating devices, the efficient rotation of the wheel bodies is not influenced; second bearings are mounted at the other ends of the lug type plate rotating devices; when a push block and a steel wire rope below thewinch penetrate through the two wheel bodies, the wheel bodies can be opened in the advancing direction of the push block due to the existence of horizontal springs; at the moment when the push blockleaves the edges of the wheel bodies, the wheel bodies can be instantly restored to the original positions under the action of the springs, so that the steel wire rope is prevented from running out ofthe wheel bodies; and particularly, at a variable slope position, a system runs, and a variable slope push-back type wheel body group can guarantee that the steel wire rope is not ejected more quickly and effectively than a conventional common rope pressing wheel group.
本发明公开了一种无极绳绞车防弹绳加强装置,包括轮体,所述轮体的内部设置有内腔,所述轮体的顶部安装有挡片,所述内腔的顶部直径小于所述挡片的直径,所述内腔为贯通的腔体,所述内腔的底部直径大于所述内腔的顶部直径;因轮体与耳式转板器间有固定空隙,不影响轮体高效转动,且耳式转板器的另一端安装有第二轴承,绞车下方的推块与钢丝绳穿过两个轮体时,因水平弹簧的存在,轮体会沿着推块前进的方向打开,在推块离开轮体沿边的一瞬间,轮体在弹簧的作用下会瞬间恢复到原位置,保证钢丝绳不会跑出轮体之间,尤其是在变坡位置时,系统运行,变坡推回式轮体组比以往的普通压绳轮组能更快更有效的保障钢丝绳不会弹出。
