Abstract

The invention discloses an elevator safety device with an alarm function. The elevator safety device comprises a pair of first blocking slots which are formed in a well wall of an elevator well; the first blocking slots are symmetrically distributed at the two sides of a hoistway door; a second blocking slot which communicates with the pair of the first blocking slots is formed in the well wall below the hoistway door; a protective net is assembled in the first blocking slots and the second blocking slot; the protective net is mounted on a rotary mechanism; by virtue of the rotary mechanism, the protective net extends out or withdraws into the first blocking slots and the second blocking slot; a trigger switch used for regulating the position of the protective net is further arranged on the well wall; the trigger switch is triggered by being in contact with an elevator car; a tension sensor is mounted on the protective net; a limiting slot is formed in the well wall; a blocking block which is driven by a hydraulic device is assembled in the limiting slot; the tension sensor is connected to the hydraulic device through a controller; and an alarm is connected on the controller. The device can effectively prevent the occurrence of an elevator well dropping condition when the hoistway door of the elevator is abnormally opened.

Description

technical field [0001] The invention relates to an elevator safety mechanism, in particular to an elevator safety device with an alarm function. Background technique [0002] Straight-running elevators have been widely installed in current high-rise buildings, and as elevators are used more and more frequently, safety problems related to elevators also occur from time to time. [0003] A relatively serious safety problem in the use of elevators is that the quality of some elevator hall doors is unqualified, or the safety is reduced due to disrepair for a long time. The typical problem is that the hall doors are pushed or bumped by external forces. If the elevator car has not reached this floor at this time, people who accidentally push the hall door will easily fall into the elevator shaft, causing casualties. In addition, if the elevator control system fails, it may also cause the hall door to suddenly open when the elevator car does not reach the floor when the up and dow...
