The invention provides elevator safety tongs and an elevator assembly, the elevator safety tongs comprise a tongs body, a positioning wedge block, a sliding wedge block and a magnetic assembly, and the tongs body is used for penetrating through a guide rail; the positioning wedge block is positioned in the clamp body; the positioning wedge block is provided with a first inclined surface; the sliding wedge block is in sliding connection with the positioning wedge block; the magnetic assembly comprises an electromagnet and a magnetic piece. The electromagnet is installed on the clamp body. Magnetic acting force exists between the magnetic piece and the electromagnet; the electromagnet is connected with the sliding wedge block, the magnetic piece is connected with the sliding wedge block and drives the sliding wedge block to slide under the magnetic acting force, electromagnetic triggering is achieved between the electromagnet and the magnetic piece instead of mechanical triggering, the triggering efficiency is improved, the triggering time is shortened, the sliding wedge block is provided with a second inclined face and a clamping face, and the second inclined face is matched with the first inclined face; the clamping face clamps the guide rail along with sliding of the sliding wedge block, so that the sliding wedge block brakes the guide rail conveniently, the elevator safety tongs clamp the guide rail, electromagnetic clamping of the elevator safety tongs is achieved, and the stopping effect of the elevator safety tongs on the guide rail is improved.
本申请提供一种电梯安全钳和电梯组件,电梯安全钳包括钳体、定位楔块、滑动楔块和磁性组件,钳体用于穿设导轨;定位楔块处于钳体内;定位楔块设有第一斜面;滑动楔块与定位楔块滑动连接;磁性组件包括电磁铁和磁性件,电磁铁安装于钳体;磁性件与电磁铁之间存在磁性作用力;磁性件连接于滑动楔块,并在磁性作用力下带动滑动楔块滑动,电磁铁和磁性件之间实现电磁式触发,并非机械式触发,提高了触发效率,缩短触发时间,滑动楔块设有第二斜面和夹持面,第二斜面与第一斜面相匹配;夹持面随着滑动楔块的滑动而夹持导轨,以便于滑动楔块制动导轨,从而电梯安全钳夹持住导轨,实现了电梯安全钳的电磁式夹持,提升电梯安全钳对导轨的制停效果。
