The invention discloses a synchronous gradually-changing pressing rope clamping friction energy absorber for an inclined shaft sliding-down protection device. The synchronous gradually-changing pressing rope clamping friction energy absorber comprises a main steel wire rope, a lower clamping plate, an upper clamping plate, a floating pressing unit, a plurality of gradually-changing pressing devices, a rope-driven rotating device and a machine shell. The rope-driven rotating device comprises a gear shaft only capable of rotating, a rope storage disc wheel fixed to the top end of the gear shaft, and a thin steel wire rope fixedly connected to the rope storage disc wheel and stored around the rope storage disc wheel, and the other end of the thin steel wire rope is fixedly connected with the main steel wire rope; the gradually-changing pressing device comprises a double-thread shaft and a large gear which is coaxially connected to the double-thread shaft in series and meshed with the gear shaft, and the large gear is coaxially matched with a guide section of the double-thread shaft in a sliding mode and transmits torque. When the sports car is braked, the main steel wire rope is pulled and drives the thin steel wire rope to move so as to drive the gear shaft to rotate, then all the large gears are synchronously driven to enable all the double-thread shafts to rotate and axially move, and then the overall pressing plate is synchronously driven to slowly and downwards press the spring. Therefore, the friction braking force of the main steel wire rope is slowly increased.

    本发明公开了一种斜井跑车防护装置用同步渐变压紧的夹绳摩擦吸能器,包括主钢丝绳、下夹板和上夹板、浮动压紧单元、若干渐变压紧装置、绳驱旋转装置和机壳;绳驱旋转装置包括仅可旋转的齿轮轴、与齿轮轴顶端固定的储绳盘轮、固接于储绳盘轮并绕其存储且另一端与主钢丝绳固接的细钢丝绳;渐变压紧装置包括双螺纹轴、同轴串接于双螺纹轴且与齿轮轴啮合的大齿轮,大齿轮与双螺纹轴的导向段同轴滑动配合并传递扭矩;渐变压紧装置沿齿轮轴周向均匀布置若干个,跑车制动时主钢丝绳被牵拉并带动细钢丝绳运动来驱动齿轮轴旋转,再同步驱动各大齿轮来使各双螺纹轴旋转和轴向运动进而同步驱动整体压板缓慢向下压紧弹簧,以此缓慢增加主钢丝绳的摩擦制动力。
