The elevator safety tongs with the speed limiting protection function comprise a safety tongs body internally provided with a velometer, a movable wedge block cover plate is fixed to the top of the safety tongs body, and an electromagnetic vertical block is fixedly installed at the front end of the top of the safety tongs body; a magnetic support block is slidably connected to the front end of the top of the safety tongs body, a driving rack is mounted in the cavity, a linkage rod is mounted on the surface of one side of the magnetic support block, a shaft column is connected to the end of the linkage rod, a follow-up gear sleeves the surface of the shaft column, and a lifting wedge block is mounted on the inner side of the safety tongs body. The surface of the rotating shaft rod is sleeved with a speed-limiting stretching rod, an electromagnetic vertical block, a velometer, the speed-limiting stretching rod, a driving rack and a follow-up gear are matched, and when the speed-limiting stretching rod works normally or abnormally, an effective pushing effect can be provided, so that a lifting wedge block is tightly held with a guide rail, and speed limiting treatment is achieved; and meanwhile, the cost expenditure required during electromagnetic driving is reduced.

    本发明涉及电梯安全技术领域的一种带有限速保护的电梯安全钳,包括有内部安装有测速器的安全钳本体,安全钳本体的顶部固定有活动楔块盖板,安全钳本体顶部的前端位置处固定安装有电磁立块,安全钳本体顶部的前端位置处滑动连接有磁动支块,空腔的内部安装有驱动齿条,磁动支块的一侧表面安装有链接杆,链接杆的端部连接有轴柱,轴柱的表面套接有随动齿轮,安全钳本体的内侧安装有提拉楔块,旋转轴杆的表面套接有限速拉伸杆,利用电磁立块、测速器和限速拉伸杆、驱动齿条和随动齿轮的配合,在限速拉伸杆正常或非正常工作时,均能提供有效的推动作用使得提拉楔块得以与导轨抱紧实现限速处理,同时降低电磁驱动时需要的成本支出。
