The invention belongs to the technical field of elevator safety tongs, and discloses an elevator safety tong with a limiting structure, which comprises a fixed seat, a group of wedge blocks are symmetrically arranged in the fixed seat, and tong body assemblies are movably connected in the wedge blocks. Through cooperation of structures such as a clamp body assembly, a moving assembly, a cylinder and a first clamping plate, the overall clamping force and the limiting effect of the device are improved, then the elevator running safety is improved, two safety clamp bodies move in the opposite directions, then the safety clamp bodies drive a second clamping plate to abut against a guide rail, and the safety of the elevator is improved. A protruding rod on the outer wall of a cylinder is movably clamped into a guide groove, so that when a rotating cylinder rotates, the protruding rod drives the cylinder and a first clamping plate to move in the direction of a guide rail along the track of the guide groove, then the first clamping plate and two second clamping plates apply clamping force to the guide rail at the same time, and the overall limiting effect of the device is improved; and therefore, the running safety of the elevator is improved.

    本发明属于电梯安全钳技术领域,且公开了一种具有限位结构的电梯安全钳,包括固定座,所述固定座的内部呈对称设置有一组楔块,所述楔块的内部活动连接有钳体组件。通过钳体组件、移动组件、圆筒和第一夹持板等结构之间的配合,从而提高装置整体的夹持力和限位效果,进而提高了电梯运行的安全性,通过两个安全钳本体相向移动,进而使安全钳本体带动第二夹持板与导轨抵接,通过圆筒外壁的凸杆活动卡接在引导槽的内部,从而使得转筒在旋转时,凸杆沿着引导槽的轨迹带动圆筒和第一夹持板朝导轨的方向移动,进而使第一夹持板和两个第二夹持板同时对导轨施加的夹持力,从而提高装置整体的限位效果,进而提高电梯运行的安全性。
