The invention discloses a safety plier of a high-speed elevator. The safety plier comprises a plier body, a top block, a pair of positioning wedge blocks and a pair of movable wedge blocks, the top block is fixed on the plier body, and the pair of positioning wedge blocks are respectively arranged in the top block through springs and are symmetrical about the center line of the top block; and pull rods are arranged at the tops of the movable wedges and penetrate out of the top of the plier body, the movable wedges are attached to the wedge-shaped faces of the positioning wedges and linearly slide along the positioning wedges, so that the distance between the movable wedges is gradually changed, when the distance is reduced, the movable wedges and elevator guide rails are in friction braking, and the faces, in friction with the guide rails, of the movable wedges are coated with cooling coatings. In the high-speed running process of the elevator, the cooling coatings coated on the opposite surfaces of the movable wedge blocks can effectively prevent heat transfer, so that the internal structure of a movable wedge block material is prevented from being damaged by overheating, the safety is enhanced, the durability is also improved, and the service life is prolonged.
本发明公开一种高速电梯的安全钳,包括钳体、顶块、一对定位楔块以及一对活动楔块;顶块固定在钳体上,一对定位楔块各通过弹簧安装在顶块中且关于顶块的中线对称;活动楔块顶部设拉杆穿出钳体顶部,活动楔块贴于定位楔块的楔形面并沿其直线滑动,致使活动楔块之间间距逐渐改变,当间距减小,活动楔块与电梯导轨摩擦制动,活动楔块上和导轨发生摩擦的一面涂覆降温涂层。电梯高速运行过程中,有涂覆在活动楔块相对面上的降温涂层有效阻止热量传递,避免过热损坏活动楔块材料内部组织,增强安全性,也提高耐用性、延长使用寿命。
