Embodiment Construction

[0027] The present disclosure provides a starting control circuit, a control method and an elevator for an automatic rescue device of an elevator. A pair of normally open auxiliary contacts of the main switch of the power supply are connected to the self-monitoring circuit and also connected to the automatic rescue starting circuit , the on-off operation of the normally open auxiliary contact is used as the manual start control signal for automatic rescue. The start control method is simple, and only needs to ensure the correct connection of the circuit. The control does not occupy the internal space of the elevator, does not need to change the original device layout of the control cabinet, does not need to add installation brackets, and does not need to drill additional holes on the original cabinet, etc. It is easy to implement and lower in cost; the start-up control circuit is designed ingeniously, no need A self-resetting switch needs to be added to ensure high reliability....

Abstract

The invention discloses a starting control circuit of an automatic rescue device of an elevator, a control method and the elevator. The starting control circuit comprises a power supply main switch and a power supply control panel. The power supply main switch comprises a main contact and a normally open auxiliary contact. The power supply control panel comprises a self-monitoring circuit and an automatic rescue starting circuit. The automatic rescue starting circuit comprises a first contactor, a second contactor and a circuit switching control relay. And the self-monitoring circuit is used for being connected with two contacts of the normally open auxiliary contact. And the circuit switching control relay is connected with the first contactor and the second contactor and is connected with the control end of the emergency rescue power supply. And the circuit switching control relay is configured to control whether the emergency rescue power supply is turned on or not and control the emergency rescue power supply or the power grid to supply power to the elevator according to a monitoring result of the self-monitoring circuit. And two contacts in the normally open auxiliary contactsare respectively connected to the control end of the emergency rescue power supply and the circuit switching control relay.

Description

technical field [0001] The disclosure belongs to the technical field of elevator control, and relates to a starting control circuit of an automatic rescue device, a control method and an elevator. Background technique [0002] Article 2.8(9)④ of Chinese regulations "Elevator Supervisory Inspection and Periodic Inspection Rules - Traction and Forced Drive Elevators" (TSG T7001-2009, including Amendment No. There are the following regulations: "A non-automatic reset switch shall be provided. When the switch is in the closed state, the automatic rescue device cannot start the rescue operation." [0003] Some elevator manufacturers use separate automatic rescue devices that are relatively independent of the elevator control system to realize automatic rescue in the event of power failure or grid failure. This split-type automatic rescue device is generally wall-mounted and relatively independently installed on the wall at the upper end of the machine room or well. The device i...
