The invention discloses a dual-way brake safety clamp. The clamp comprises a clamp body, two symmetric positioning blocks are mounted in the clamp body, an elastic material is mounted between the positioning blocks and the clamp body, opposite cubic through holes are formed in the positioning blocks, clamping devices are arranged in the through holes, a first rotating shaft is mounted in a mannerof penetrating the middle of each clamping device and the corresponding positioning block, a second rotating shaft and a third rotating shaft are arranged in a manner of penetrating through the upperand the lower of each positioning block, the side faces of the second rotating shafts and the third rotating shafts abut against the clamping devices, the second rotating shafts and the third rotatingshafts are externally connected with rotating motors, in the rotating process, the contact distances between the centers of the second rotating shafts and the third rotating shafts and the clamping devices are changeable, according to the technical scheme, a conventional steel wire rope is not used, through control over a power device of the dual-way brake safety clamp, action parts can be further controlled to act, speeding up and speeding down dual-way clamping brake stop can be achieved, a speed limiter is not needed, the structure is simple, the response is rapid, and the clamp is safer.

    本发明的双向制动安全钳,包括钳体,所述钳体内设有两个对称的定位块,所述定位块和所述钳体之间设有弹性材料,所述定位块内开有相对的立方体通孔,所述通孔内放置有夹紧装置,穿过所述夹紧装置的中间和所述定位块设有第一转轴,穿过每个所述定位块的上下各位置设有第二转轴和第三转轴,所述第二转轴和所述第三转轴的侧面抵在所述夹紧装置上,所述第二转轴和所述第三转轴外接旋转电机,在转动过程中,所述第二转轴和所述第三转轴的中心与所述夹紧装置接触的距离可变。本发明的技术方案不使用常规的钢丝绳,通过控制双向制动安全钳的动力装置,进而控制动作部件动作,实现上行超速和下行超速双向夹持制停,无需限速器,结构简单,响应快,更安全。
