Abstract
The invention relates to elevator manufacturing technologies, in particular to a safety technology for dealing with accidental falling of an elevator. An elevator car, a steel rope, an elevating motor and an elevator car elevating passage are included. A buffering device is arranged at the bottom, under the elevator car, of the elevator passage and comprises a swinging frame, a swinging disc, a swinging fulcrum with a bearing, a swinging disc stabilization ring and a bolt. By changing the direction of the falling force of the accidentally-falling elevator, the straight-line falling force of the falling elevator car is converted into bend curve force, the curve force is converted into swinging force, the swinging force is gradually decreased to be zero under the straight-line perpendicularity effect of force, and then the accidentally-falling elevator can be in a static safe state. The buffering device is low in production cost, convenient to use and practical.
