Elevator Fall Protection

Abstract

The invention belongs to the technical field of hoisting equipment in a fixed place, and particularly relates to a lift dropping protector. The lift dropping protector comprises a machine base, an inner body capable of rotating around a main shaft is arranged in the machine base, and the inner body comprises a sampling rotating wheel, a trigger mechanism and an executing mechanism. The lift dropping protector is characterized in that the center of the sampling rotating wheel is provided with a steel through shaft, and one end of the sampling rotating wheel is provided with a synchronization bull wheel; the trigger mechanism comprises a trigger rotating wheel, centrifugal trigger heads and a trigger rod, the centrifugal trigger heads are symmetrically arranged in the direction of the vertical diameter of the trigger rotating wheel, one end of the trigger rotating wheel is provided with a synchronization small wheel, and the synchronization small wheel is connected with the synchronization bull wheel through a synchronization band; the executing mechanism comprises a releasing mechanism and a locking mechanism. According to the lift dropping protector, the structure is simple, power source is not needed, energy is saved, operation is reliable, the protector is durable in use, safe operation of a lift is guaranteed, life safety of people is maintained, the cost is low, and popularization and application are convenient.

Description

technical field [0001] The invention relates to an elevator fall protector, which belongs to the technical field of lifting equipment in fixed places. Background technique [0002] With the development of the national economy, elevators have become an indispensable tool for people's production and life.
