The electronic safety tongs comprise a base plate, clamping mechanisms and a controller, the front side of the base plate is provided with a rail body channel allowing a guide rail to penetrate through, the clamping mechanisms are installed on the left side and the right side of the rail body channel correspondingly, and each clamping mechanism comprises a machine shell, a first motor, a movable wheel, a clamping block, a transmission assembly and a second motor; the movable wheel can be driven by a second motor to rotate, the first motor can switch the positions of the movable wheel and the clamp block at the same time through a transmission assembly so that one of the movable wheel and the clamp block can be horizontally close to the guide rail and the other clamp block can be horizontally away from the guide rail, and the controller is electrically connected with the two clamping mechanisms. According to the invention, the lift car can descend to a designated position at a relatively slow speed and then stop descending immediately, so that not only are subsequent rescue and maintenance facilitated, but also people in the lift car can be effectively prevented from being collided and injured due to rapid descending and rapid stopping, and the taking safety of an elevator is improved.

    本发明公开了电子安全钳,包括基板、钳合机构和控制器,所述基板的前侧设有可供导轨穿过的轨体通道,所述轨体通道的左右两侧分别安装有钳合机构,所述钳合机构包括机壳、第一电机、活动轮、钳块、传动组件和第二电机,所述活动轮可由第二电机驱动自转,所述第一电机可通过传动组件同时对活动轮和钳块进行位置切换以使其中一个水平靠近导轨而另一个水平远离导轨,所述控制器分别与两组钳合机构电连接,能够使轿厢以相对较慢的速度下降至指定位置之后再立即停止下降,不仅方便后续施救和维修,还可有效避免轿厢内的人员因速降和速停而碰撞受伤,提高电梯乘坐的安全性。
