The invention discloses a multi-stage reinforcement and long-distance buffering rope clamping energy absorber for inclined shaft sliding-down protection. The multi-stage reinforcement and long-distance buffering rope clamping energy absorber comprises an upper clamping plate, a lower clamping plate, a wedge mechanism, a double-thread shaft, a rope drive transmission device and the like, wherein the upper clamping plate and the lower clamping plate clamp a main steel wire rope; the tapered wedge mechanism comprises a lower tapered wedge block fixedly connected with the integral pressing plate and an upper tapered wedge sliding block matched with the lower tapered wedge block, and the upper tapered wedge sliding block is provided with a threaded hole A; the double-thread shaft is provided with an external thread A, an external thread B and a guide section; the threads are respectively matched with the threaded hole A and the threaded hole B of the base; the large bevel gear is matched with the guide section to transmit torque and slides relative to the guide section, the small bevel gear is fixed to the transmission shaft and meshed with the large bevel gear, the rope storage disc wheel is fixed to the transmission shaft, and the thin steel wire rope is fixedly connected to the rope storage disc wheel and fixedly connected with the main steel wire rope. In the working process, the main steel wire rope is pulled to drive the thin steel wire rope to drive the double-thread shaft, the upper wedge sliding block drives the lower wedge block to downwards press the spring, and therefore the friction braking force of the main steel wire rope is slowly increased.

    本发明公开了一种多级增力与长距缓冲的斜井跑车防护用夹绳吸能器,包括夹紧主钢丝绳的上夹板和下夹板、驱动整体压板压紧弹簧的斜楔机构、双螺纹轴、绳驱传动装置等;斜楔机构包括与整体压板固接的下斜楔块和与其配合的上斜楔滑块,上斜楔滑块设有螺纹孔A;双螺纹轴设有外螺纹A、外螺纹B和导向段,螺纹分别与螺纹孔A和机座的螺纹孔B配合;绳驱传动装置包括与导向段配合传扭矩且相对滑动的大锥齿轮、固于传动轴且与大锥齿轮啮合的小锥齿轮、固于传动轴的储绳盘轮、固接于储绳盘轮并与主钢丝绳固接的细钢丝绳;工作时主钢丝绳被牵拉带动细钢丝绳来驱动双螺纹轴,使上斜楔滑块驱动下斜楔块向下压紧弹簧,以此缓慢增加主钢丝绳的摩擦制动力。
