The invention belongs to the technical field of elevator parts, and particularly relates to a two-way lifting mechanism which comprises a pair of lifting assemblies, each lifting assembly comprises a base, a two-way lifting arm, a swing arm and a safety tongs linkage arm, and a rotating shaft is installed between the bases of the lifting assemblies; the two ends of the rotating shaft are connected with the two swing arms respectively, the two-way lifting arm is connected with the swing arms through rotating pairs, and the safety tongs linkage arm is installed on the swing arms in a sliding mode, so that the two-way lifting arm lifts or pulls down the swing arms to be in linkage with the safety tongs linkage arm to lift the safety tongs, and the rotating shaft is in synchronous linkage with the two-way lifting arm to rotate. The safety tongs linkage arm is in sliding fit with the swing arm so as to be matched with the lifting stroke of the safety tongs. According to the bidirectional lifting mechanism, the bidirectional safety tongs can be lifted in a bidirectional mode, so that triggering and resetting of the bidirectional safety tongs are achieved, and the bidirectional lifting mechanism is simple in structure and used in cooperation with a bidirectional speed limiter and the bidirectional safety tongs.

    本发明属于电梯部件技术领域,具体涉及一种双向提拉机构,包括一对提拉总成,提拉总成包括基座、双向提拉臂、摆动臂和安全钳联动臂,各提拉总成的基座之间安装有转动轴;转动轴的两端分别与两摆动臂连接,双向提拉臂与摆动臂采用转动副连接,安全钳联动臂滑动安装于摆动臂,以通过双向提拉臂上提或下拉摆动臂而联动安全钳联动臂提拉安全钳,且同步联动转动轴转动;其中,安全钳联动臂滑动配合于摆动臂,以匹配安全钳的提拉行程。本发明的双向提拉机构,能够双向提拉双向安全钳,从而实现双向安全钳的触发及复位,且结构简单,配套双向限速器和双向安全钳使用。
