The invention provides safety tongs for a high-rise building elevator, and relates to the technical field of building safety. Locking blocks are fixed to the two sides in the pincer body shell, a trapezoidal section is formed in the front face of the pincer body shell, mounting grooves are formed in the two sides of the trapezoidal section respectively, inner cavities of the mounting grooves are movably connected with double-wedge-shaped sliding block mechanisms through traction mechanisms, a safety lifting rope is arranged between the two double-wedge-shaped sliding block mechanisms, and a connecting base is arranged at the bottom of the pincer body shell. Stroke grooves are formed in the front face and the back face of an inner cavity of the caliper body shell respectively, the double-wedge-shaped sliding block mechanisms can transversely and longitudinally move along the stroke grooves, and a triggering mechanism is arranged on the front face of the caliper body shell and can transversely push the two sets of double-wedge-shaped sliding block mechanisms to make the double-wedge-shaped sliding block mechanisms generate relative friction with a safety lifting rope when an elevator car body moves downwards or upwards at an overspeed. And under the action of friction force, the clamp body moves downwards or upwards relative to the clamp body shell and then abuts against the locking block to be locked. By arranging the bidirectional wedge blocks, bidirectional braking can be achieved, and the practicability of the device is improved.

    本发明提供了一种用于高层建筑电梯的安全钳,涉及建筑安全技术领域。其包括:钳体外壳,其内两侧固定有锁定块,钳体外壳正面开设有梯形断面,梯形断面两侧分别开设有安装槽,各安装槽内腔通过牵拉机构与双楔形滑块机构活动连接,两组双楔形滑块机构间设有安全吊绳,钳体外壳底部有连接底座,钳体外壳内腔正背面分别设行程槽,双楔形滑块机构可沿行程槽横向和纵向移动,钳体外壳正面设有触发机构,能够在电梯轿厢主体超速向下或向上运动时,将两组双楔形滑块机构横向推动,使其与安全吊绳产生相对摩擦,在摩擦力作用下相对钳体外壳向下或向上移动,进而与锁定块抵触锁死。本发明通过设置双向的楔块便可实现双向刹车,提高了该装置的实用性。
