The invention relates to the technical field of lifting devices, in particular to a single-rope winding type mine hoist energy recovery system which is characterized in that a winding drum is connected with a motor, and a connecting rope is wound on the winding drum; one end of the connecting rope is fixed on the reel, and the other end is connected with the mine container; the winding drum rotates to drive the mine container to ascend; the mine container descends under the gravity; the transmission is provided with a reversing structure; the input end of the reversing structure is connected with the reel; the flywheel is connected with the output end of the reversing structure; when the mine container descends or brakes, the flywheel rotates to store kinetic energy, and when the mine container ascends, the reversing structure reverses, the flywheel rotates, and the kinetic energy is transmitted to the winding drum through the reversing structure; gravitational potential energy or braking energy of a mine container is directly converted into flywheel kinetic energy to be stored; and through the reversing structure, the rotation direction of the flywheel is always the same as that of the winding drum to assist in lifting the mine container, so that energy is saved, and impact on a power grid caused by frequent starting and rising of the mine container is reduced.
本发明涉及提升装置技术领域,具体涉及一种单绳缠绕式矿井提升机能量回收系统,包括:卷筒与电动机连接,卷筒缠绕连接绳;连接绳一端固定于卷筒上,另一端与矿井容器连接;卷筒旋转,带动矿井容器上升;矿井容器在重力下下降;变速器设有换向结构;换向结构输入端与卷筒连接;飞轮与换向结构输出端连接;飞轮在矿井容器下降或制动时,转动动能存储,在矿井容器上升时,换向结构换向,飞轮转动,将动能通过换向结构传至卷筒;本申请将矿井容器重力势能或制动能直接转化为飞轮动能存储;并通过换向结构,使飞轮旋转方向始终与卷筒转动方向相同,辅助提升矿井容器,不仅节能,且减小矿井容器频繁启动上升对电网的冲击。
