The invention discloses a self-driven long-distance flexible friction plate energy absorber for a rope winding roller. Comprising a fixed mandrel fixed to a machine base, a roller rotating around the fixed mandrel, a steel wire rope, a fixed friction plate installed on the fixed mandrel, a movable friction plate installed in the roller, a spring pressing the friction plates, a double-thread cylinder and a transmission device transmitting rotation of the roller to the double-thread cylinder to achieve rotation and axial translation of the double-thread cylinder. The sliding nut slides coaxially with the fixed mandrel; an internal thread A is arranged in the middle of the machine base, the double-thread cylinder is of a double-layer cylinder structure, an external thread B and an internal thread B which are identical in screwing direction are arranged on an inner cylinder of the double-thread cylinder structure, the pitch of the external thread B is slightly larger than that of the internal thread B, and the external thread B and the internal thread B are matched with the internal thread A and external threads of the sliding nut respectively. During working, the steel wire rope drives the roller to rotate, the transmission device synchronously drives the double-thread cylinder to rotate and axially move, the sliding nut slowly compresses the spring, the long-distance autonomous buffering braking advantage is achieved, the safety of an inclined shaft man/machine is effectively guaranteed, the structure is simple, and operation is reliable.

    本发明公开了一种卷绳滚筒自驱动式长距柔性摩擦片吸能器,包括固定于机座的固定心轴、绕固定心轴旋转的滚筒、钢丝绳、安装于固定心轴的定摩擦片、安装于滚筒内的动摩擦片、压紧摩擦片的弹簧、双螺纹筒、将滚筒的旋转传递给双螺纹筒实现其旋转和轴向平移的传动装置、同轴于固定心轴滑动的滑动螺母;机座中间设有内螺纹A,双螺纹筒为双层圆柱筒结构,其内侧圆柱筒设有旋向相同的外螺纹B和内螺纹B且前者螺距略大于后者,它们分别与内螺纹A和滑动螺母的外螺纹配合;工作时钢丝绳带动滚筒旋转并由传动装置同步驱动双螺纹筒旋转且轴向运动,使滑动螺母缓慢压紧弹簧,具有长距离自主式缓冲制动优势,有效保障斜井人/机安全,且结构简单、运行可靠。
