The invention relates to elevator rescue equipment, method and device and a storage medium. The elevator rescue equipment comprises a standby power supply, a control circuit and a brake, wherein the standby power supply is connected to the control circuit and the brake respectively; the control circuit receives a power-on signal and indicates the standby power supply to supply power to the brake;and the control circuit acquires the continuous power supply duration of the standby power supply, and indicates the standby power supply to stop supplying the power to the brake in order to enable the brake to perform braking action under the condition that the continuous power supply duration is greater than the preset duration. When the standby power supply supplies the power to the brake for along time or continuously due to human factors or other reasons, the brake is opened for a long time or continuously to cause long-time or continuous release of the braking of a traction machine. Bymeans of the elevator rescue equipment, safety accidents in the rescue process due to the fact that the elevator loses power and then is connected into the standby power supply to cause too high running speed can be prevented, and the elevator safety can be improved.
本申请涉及一种电梯救援设备、方法、装置和存储介质。其中,电梯救援设备,包括备用电源、控制电路和制动器;备用电源分别连接控制电路和制动器;控制电路接收到通电信号,指示备用电源向制动器供电;控制电路获取备用电源的持续供电时长,并在持续供电时长大于预设时长情况下,指示备用电源停止向制动器供电以使制动器进行制动动作。当因人为或其它原因导致备用电源长时间或持续为制动器供电时,制动器长时间或持续打开,导致曳引机制动长时间或持续解除。而通过上述电梯救援设备可以防止电梯失电后接入备用电源导致运行速度过快,从而致使救援过程中发生安全事故,有益于提高电梯安全性。
