The invention relates to an electronic trigger type safety gear which comprises a gear body provided with a guide rail channel, a brake roller and a fixed wedge which are installed on the gear body and located on the two sides of the guide rail channel respectively, and an electronic trigger piece installed on the gear body and used for replacing a traditional lifting mechanism. The brake roller is driven to move along the caliper body to approach the guide rail to realize braking; the two ends, in the guide rail channel direction, of the fixed wedge block abut against the clamp body and the displacement reset mechanism correspondingly, and the displacement reset mechanism is used for providing a displacement stroke for the fixed wedge block when the safety clamp is reset and resetting the fixed wedge block after displacement. According to the safety tongs, electronic triggering is achieved, and the reset force is small.
本发明涉及一种电子触发式安全钳,包括钳体,钳体具有导轨通道,还包括安装于钳体的制动滚柱和固定楔块,制动滚柱与固定楔块分别位于导轨通道的两侧,还包括安装于钳体的电子触发件,电子触发件用于替代传统的提拉机构,驱动制动滚柱沿钳体运动贴近导轨实现制动;所述固定楔块沿导轨通道方向的两端分别抵接于钳体和位移复位机构,位移复位机构用于在安全钳复位时为固定楔块提供位移行程以及位移之后的固定楔块的复位。本发明的安全钳,实现电子触发,且复位力较小。
