The invention discloses a lifting device for elevator safety tongs. The lifting device comprises a speed limiter steel wire rope and a speed limiter lifting rod. The speed limiter steel wire rope is connected with the long handle end of the speed limiter lifting rod; the short handle end of the speed limiter lifting rod is hinged to a first swing assembly and/or a second swing assembly. The short handle end of the speed limiter lifting rod is connected with a third swing assembly and/or a fourth swing assembly through a linkage assembly. The first swing assembly, the second swing assembly, the third swing assembly and the fourth swing assembly are connected with a first safety gear, a second safety gear, a third safety gear and a fourth safety gear correspondingly. The linkage assembly is provided with an action switch used for cutting off an elevator safety circuit. By changing the number of the swing rods, the connecting rods and the safety tongs lifting rods, a double-lifting-point or four-lifting-point structure can be achieved. When the safety tongs are of a four-lifting-point structure, the lifting synchronism of the safety tongs can be achieved by changing the initial installation position of the lifting rod of the speed limiter or changing the length relation of the swing rod and the connecting rod.

    本发明公开了一种电梯安全钳提拉装置,包括限速器钢丝绳和限速器提拉杆;限速器钢丝绳与限速器提拉杆的长柄端连接;限速器提拉杆的短柄端铰接有第一摆动组件和/或第二摆动组件;限速器提拉杆的短柄端通过联动组件连接有第三摆动组件和/或第四摆动组件;第一摆动组件、第二摆动组件、第三摆动组件和第四摆动组分别连接有第一安全钳、第二安全钳、第三安全钳和第四安全钳;所述联动组件上安装有用于切断电梯安全回路的动作开关;本发明通过改变摆杆、连杆和安全钳提拉杆的数量,可以实现双提拉点或四提拉点的结构。当为四提拉点的结构时,可以通过改变限速器提拉杆的初始安装位置,或者摆杆、连杆的杆长关系,实现安全钳提拉的同步性。
