The invention belongs to the technical field of elevator safety tongs, and discloses a wear-resistant elevator safety tongs which comprises a shell, limiting plates are slidably connected into the shell, the ends, away from each other, of the limiting plates are fixedly connected with adjusting bolts, and the ends, close to each other, of the limiting plates are fixedly connected with buffer springs. By arranging the reset assembly, the brake device has the advantage of being capable of automatically resetting the brake wedge block, the brake device rotates through friction between a friction rotating wheel and a guide rail, the friction rotating wheel pushes a reset sliding block to move downwards through a gear and teeth, the brake wedge block can be automatically reset through the reset sliding block, and the brake wedge block can be automatically reset. By arranging the adjusting assembly, the brake device has the advantage that the friction surface can be adjusted, and when the brake wedge block is reset, the sliding rod slides downwards from the interior of the first sliding groove and enters the second sliding groove through the limiting baffle to drive the brake wedge block to move.
本发明属于电梯安全钳技术领域,且公开了一种耐磨型电梯安全钳,包括外壳,所述外壳内部滑动连接有限位板,所述限位板相互远离的一端均固定连接有调节螺栓,所述限位板相互靠近的一端固定连接有缓冲弹簧,所述外壳内部活动连接有固定楔块,所述固定楔块外侧滑动连接有滑动限位块,本发明通过设置复位组件,具有能够自动复位制动楔块的优点,通过摩擦转轮与导轨摩擦从而转动,由摩擦转轮通过齿轮和齿牙推动复位滑块向下移动,进而由复位滑块推动制动楔块向下移动,通过设置调节组件,具有能够调节摩擦面的优点,通过制动楔块复位时滑杆从第一滑槽内向下滑动,由限位挡板进入第二滑槽,带动制动楔块移动。
