Isolation device for elevator hall door

Abstract

The invention discloses an elevator landing door isolation device. The elevator landing door isolation device comprises a plurality of isolation devices and an elevator control device, wherein the isolation devices correspond to respective elevator landing door openings and are used for shielding or exposing the elevator landing door openings; the elevator control device is used for synchronously controlling actions of the plurality of isolation devices; each isolation device comprises a controller connected with the elevator control device through a connection cable, a direct-current tubular electric motor connected with the controller, a roller blind shaft connected with a motor shaft of the direct-current tubular electric motor as well as an isolation curtain winding around the roller blind shaft. The elevator landing door isolation device can timely isolate an elevator in an abnormal use state, prevents passengers from entering the elevator by mistake and guarantees safety of the passengers when the passengers take the elevator; the isolation devices can be timely put away, the workload consumed when a maintenance worker puts away the isolation devices is saved, the maintenance worker can attentively maintain the elevator, the maintenance time is shortened, and the maintenance efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of elevator control, in particular to an elevator hall door isolation device capable of preventing passengers from accidentally entering an elevator in an abnormal use state. Background technique [0002] The elevator sometimes enters into an abnormal use state during failure, inspection, maintenance and debugging. For example, after the maintenance personnel deal with the elevator failure, they will exit the maintenance state for trial operation to confirm whether the fault is eliminated. During the trial operation, maintenance The security personnel cannot guarantee whether the elevator is safe to run. Therefore, the elevator is not in normal use during the trial run, and passengers are not allowed to enter. However, in actual operation, it is difficult for passengers to distinguish whether the elevator is allowed to be used. If a passenger enters an elevator in an abnormal use state by mistake, the person...

AI Technical Summary

Problems solved by technology

However, in actual operation, due to the inconvenient transportation of the isolation barrier and the need for manual setting, etc., it will result in failure to place or evacuate the isolation barrier in time. Risk; if the elevator is in normal use and fails to evacuate the barrier in time, it will affect the normal use of passengers
