The invention discloses a long buffer steel belt type energy absorber for an inclined shaft sliding-down protective device, which comprises a coiled steel belt arranged in a shell, a movable compression roller and a fixed compression roller for bending part of the steel belt, and a reinforcement micro-motion unit for adjusting the compression feed amount of the movable compression roller, the reinforcement micro-motion unit comprises a rope storage wheel, a traction rope wound around the rope storage wheel, a differential threaded shaft which is driven by the rope storage wheel to rotate and can slide axially, a sliding nut, a toggle reinforcement mechanism and the like. An external thread B and an external thread A of the differential threaded shaft are in threaded fit with the sliding nut and the machine shell respectively. The external thread B and the external thread A have the same screwing direction, the screw pitch of the external thread B is slightly smaller than that of the external thread A, the steel belt drives the differential threaded shaft to rotate and move when being pulled out, the sliding nut slowly pulls the toggle reinforcement mechanism rightwards to enable the movable compression roller to compress the steel belt, and long-distance flexible buffering braking is achieved. And the safety of the man/machine for braking the inclined shaft sports car is guaranteed.

    本发明公开了一种斜井跑车防护装置用长缓冲钢带式吸能器,包括安装于机壳内的盘曲钢带、压弯部分钢带的动压辊和定压辊、调节动压辊压紧进给量的增力微动单元,该增力微动单元包括储绳轮、绕于储绳轮的牵引绳、由储绳轮带动旋转且可轴向滑动的差动螺纹轴、滑动螺母、肘节增力机构等,该差动螺纹轴的外螺纹B和外螺纹A分别与滑动螺母、机壳进行螺纹配合;牵引绳另一端通过导向滚轮整向后与钢带拉出末端固接,外螺纹B与外螺纹A的旋向相同且前者螺距略小于后者,钢带拉出时带动差动螺纹轴旋转且移动,而滑动螺母缓慢向右拉动肘节增力机构使动压辊压紧钢带,实现长距离柔性缓冲制动,保障斜井跑车制动的人/机安全,具有结构紧凑、维护简单优势。
