The invention discloses a safety gear reset device, an elevator and a safety gear reset method, and belongs to the technical field of elevators. The safety gear reset device comprises a rigging assembly, the rigging assembly comprises a first rigging rod, a second rigging rod and a rigging sleeve with a hollow inner cavity, and one end of the first rigging rod and one end of the second rigging rodextend into the hollow inner cavity from the two ends of the rigging sleeve respectively; and the first rigging rod is provided with a first external thread, the second rigging rod is provided with asecond external thread, the rotating direction of the first external thread is opposite to that of the second external thread, and the two ends of the hollow inner cavity are provided with a first internal thread and a second internal thread which can be connected with the first external thread and the second external thread in a matched mode respectively. A safety gear can be reset without a standby power supply, the operation is very simple, the counterweight can descend and a lift car can ascend as long as the rigging sleeve rotates relative to the first rigging rod and the second riggingrod to enable the first rigging rod and the second rigging rod to get close, and finally the safety gear is reset.

    本发明公开一种安全钳复位装置、电梯及安全钳复位方法,属于电梯技术领域,其包括索具组件所述索具组件包括第一索杆、第二索杆和具有中空内腔的索套,所述第一索杆与所述第二索杆中一端分别由锁套的两端伸入中空内腔中,所述第一索杆设置有第一外螺纹,所述第二索杆设置有第二外螺纹,所述第一外螺纹与所述第二外螺纹的旋向相反,所述中空内腔的两端部设置有能分别与第一外螺纹、第二外螺纹匹配相连的第一内螺纹和第二内螺纹。本发明无需设置备用电源便可复位安全钳,操作也十分的简单,只需让索套相对第一索杆、第二索杆转动,使得第一索杆和第二索杆靠近,便能使得对重下行,轿厢上行,最终实现对安全钳的复位。
