The invention discloses an auxiliary device for elevator safety tongs, which relates to the technical field of safety tongs and comprises a lift car, a bottom plate and a support. A guide rail is connected to the back face of the lift car, a mounting frame is arranged on one side of the guide rail, and a safety gear device is arranged in the mounting frame. A mechanical locking device is arranged on the side, away from the mounting clamp device, of the guide rail. During normal operation, the mechanical locking device is kept in a loose state and does not interfere with operation of an elevator, when an elevator control system detects overspeed descending, the safety tongs device and the mechanical arm are triggered to push a jaw to clamp a guide rail, meanwhile, the mechanical locking device is activated, and a first rack is pushed to move through a first gear; a first rack pushes a first pushing block through two second pushing rods, through a triangular structure of the first pushing block, a first fixing rod fixes the two first pushing rods to drive a second clamping ring to limit a clamping rod on a guide rail, and a first clamping ring limits the clamping rod on the guide rail.

    本发明公开了一种电梯安全钳的辅助装置,涉及安全钳技术领域,包括轿厢、底板和支架;所述轿厢背面连接有导轨,所述导轨一侧设有安装架,所述安装架内设有安全钳装置;所述导轨远离安装钳装置的一侧设有机械锁紧装置。本发明正常运行时,机械锁紧装置保持松弛状态,不会干预电梯的运行,当电梯控制系统检测到超速下降时,触发安全钳装置,机械臂推动钳口夹紧导轨,同时机械锁紧装置被激活,通过齿轮一推动齿条一移动,齿条一通过两个推动杆二对推动块一进行推动,通过推动块一的三角结构,固定杆一固定两个推动杆一带动夹紧环二对导轨上的夹持杆进行限位,夹紧环一对导轨上的夹持杆进行限位。
