The invention belongs to the technical field of elevator safety, and particularly relates to a safety tong lifting mechanism and a lifting assembly.The safety tong lifting mechanism comprises a mounting base, a rotating shaft, a cam and a lifting arm, the cam is mounted on the mounting base through the rotating shaft, and the lifting arm is in linkage connection with the cam; under the action of external force, the lifting arm is lifted or pulled down to link the cam to rotate, and the cam rotates to link the clamp body of the safety clamp to be transversely and movably matched with the mounting seat. According to the lifting mechanism for the safety tongs, the tong body of the safety tongs is driven to move transversely, so that the wedge block of the safety tongs is in contact friction with the guide rail in a linkage mode, and friction braking between the wedge block of the safety tongs and the guide rail is achieved; the safety tongs lifting mechanism is different from an existing safety tongs lifting mechanism in principle, simple in structure and convenient to install.

    本发明属于电梯安全技术领域,具体涉及一种安全钳提拉机构及提拉总成,其中,安全钳提拉机构,包括安装座、转轴、凸轮和提拉臂,凸轮通过转轴安装于安装座,提拉臂与凸轮联动连接;在外力作用下提拉臂上提或下拉以联动凸轮转动,凸轮转动以联动安全钳的钳体横向活动配合于安装座。本发明的安全钳提拉机构,通过驱动安全钳的钳体横向移动,以联动安全钳楔块与导轨接触摩擦,从而实现安全钳楔块与导轨之间的摩擦制动;与现有的安全钳提拉机构的原理不同,且结构简单,便于安装。
