The invention discloses a long-distance buffering clamping plate energy absorber and a delayed intervention braking anti-sliding device. The long-distance buffering clamping plate energy absorber comprises a plurality of main steel wire ropes, a lower clamping plate, an upper clamping plate, a floating pressing unit for applying pressing force to the upper clamping plate and a gradual change pressure applying device for applying pressing force to the floating pressing unit. Through a gradual change pressure applying device of the differential thread mechanism, the friction braking force of a main steel wire rope is slowly increased through continuous tiny feeding displacement of a large-diameter large-pitch thread, the contradiction between the thread size and tiny compression displacement under large positive pressure is effectively solved, and long-distance mechanical autonomous buffering flexible braking is achieved; the safety of people/machines for braking the sports car is ensured; according to the anti-sliding-down device with the multiple energy absorbers arranged in series or in parallel, the lower end face of the sliding nut in each energy absorber is a certain distance away from the overall pressing plate in the working state, mechanical delay autonomous intervention of each energy absorber in the braking process of a sliding down car is achieved, pure mechanical delay intervention is adopted, and a storage rope does not need to be turned over; the system has the advantages of high reliability and low maintenance cost.

    本发明公开了一种长距缓冲夹板吸能器及延时介入制动的防跑车装置,包括若干主钢丝绳、下夹板、上夹板、对上夹板施加压紧力的浮动压紧单元、对浮动压紧单元施加压紧力的渐变施压装置;通过差动螺纹机构的渐变施压装置,实现大直径大螺距螺纹的持续微小进给位移来缓慢增加主钢丝绳的摩擦制动力,有效解决了大正压力下螺纹尺寸与微小压缩位移量的矛盾,实现了长距离机械自主式缓冲柔性制动,保障跑车制动的人/机安全;由多台该吸能器串列或并列的防跑车装置,待工作状态下各吸能器中滑动螺母的下端面与整体压板相距一定距离,实现跑车制动过程各吸能器的机械延时自主介入,以纯机械式延时介入且无需折转储绳,具有可靠性高且维护成本低的优势。
