The invention belongs to the technical field of elevator accessories, and particularly relates to an electronic safety gear which comprises a gear body, a brake roller and a friction block, and the gear body is provided with a guide rail channel extending vertically, and roller paths and embedding grooves distributed on the two sides of the guide rail channel; the brake pin roller is arranged on the caliper body through the pin roller cover plate and is movably matched with the roller path; the friction block is mounted in the embedding groove of the caliper body through the limiting cover plate; the electronic safety tongs further comprise an electronic trigger piece installed on the tongs body, and are characterized in that the roller cover plate is provided with a roller movable avoiding strip-shaped hole and a cover plate transverse movable stroke hole, and the convex shaft of the brake roller is inserted into the roller movable avoiding strip-shaped hole; the pin roller cover plate penetrates through the cover plate transverse movement stroke hole through a fixing piece to be fixed to the clamp body so that the pin roller cover plate can be movably installed on the clamp body in a matched mode. In the power-off state, the electronic triggering piece drives the roller cover plate to move transversely to be close to the guide rail channel, and the roller cover plate synchronously links the braking roller to move transversely to be in contact with the elevator guide rail. The electronic safety tongs are better in safety and reliability.

    本发明属于电梯配件技术领域,具体涉及一种电子安全钳,包括钳体、制动滚柱和摩擦块,钳体具有竖向延伸的导轨通道及其两侧分布的滚道和嵌装槽;制动滚柱通过滚柱盖板安装于钳体并活动配合于滚道;摩擦块通过限位盖板安装于钳体的嵌装槽;电子安全钳还包括安装于钳体的电子触发件,其特征在于,所述滚柱盖板具有滚柱活动避让条形孔和盖板横向活动行程孔,制动滚柱的凸轴插接于滚柱活动避让条形孔;滚柱盖板通过固定件贯穿盖板横向活动行程孔固定于钳体,以使滚柱盖板活动配合安装于钳体;在失电状态下,电子触发件驱动滚柱盖板横向活动以靠近导轨通道,滚柱盖板同步联动制动滚柱横向活动至与电梯导轨接触。本发明的电子安全钳的安全可靠性更佳。
