The invention provides a double-drive multi-rope friction lifting system suitable for ultra-deep well heavy-load lifting. The double-drive multi-rope friction lifting system comprises a first friction wheel and a second friction wheel. The first friction wheel carries a first lifting first rope, one end of the first lifting first rope hangs a first lifting container, and the other end of the first lifting first rope hangs a second lifting container; the second friction wheel carries a second lifting first rope, one end of the second lifting first rope bypasses the first head sheave to suspend a second lifting container, and the other end of the second lifting first rope bypasses the second head sheave to suspend the first lifting container; the lifting system further comprises a balance tail rope, one end of the balance tail rope is hung at the bottom of the first lifting container, and the other end of the balance tail rope is hung at the bottom of the second lifting container. By adopting the double-friction-wheel double-driving unit and the two groups of multiple lifting first ropes, the total surrounding angle of the lifting first ropes on the friction wheels is increased, the friction force is doubled, the lifting load capacity is increased, and the lifting depth and the lifting load are greatly increased.

    本发明提供一种适于超深井大载重提升的双驱多绳摩擦提升系统,包括:第一摩擦轮和第二摩擦轮;第一摩擦轮搭载第一提升首绳,第一提升首绳一端悬挂第一提升容器,第一提升首绳的另一端悬挂第二提升容器;第二摩擦轮搭载第二提升首绳,第二提升首绳的一端绕过第一天轮悬挂第二提升容器,第二提升首绳的另一端绕过第二天轮悬挂第一提升容器;提升系统还包括平衡尾绳,平衡尾绳的一端悬挂在第一提升容器底部,平衡尾绳的另一端悬挂在第二提升容器底部。本发明采用双摩擦轮双驱动单元和两组多数量的提升首绳,增大了提升首绳在摩擦轮上的总围包角,其摩擦力增加了一倍,增大提升载荷量,使提升深度、提升载重大幅增加。
