Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, an elevator backup rescue system includes an elevator host 1, an elevator brake 2, a control circuit 3, a drive circuit 4, a short-circuit contactor 5, a door zone sensor 6, a door machine circuit 7 and a backup power supply 8 capable of automatic charging . The backup power supply 8 supplies power to the control circuit 3, the drive circuit 4, the elevator brake 2 and the door machine circuit 7 when the system is started, the drive circuit 4 is connected to the three-phase input terminal of the elevator host 1, and the short-circuit contactor 5 is used to short-circuit the elevator The three-phase input terminal of host 1, and keep the normally closed state. The control loop 3 detects the signal of the rotary encoder 9 on the elevator host 1 and the signal of the door zone sensor 6 in real time, and controls the action of the drive ...

Abstract

The invention relates to a backup rescue system of an elevator. When the elevator stops between two floors due to power outage, or an internal fault of a control cabinet, or other line faults, the backup rescue system of the elevator can be started to drive the elevator to reach a nearby floor, a door can be opened, and passengers can be rescued. The backup rescue system of the elevator is independent of an existing control system of the elevator, and can automatically drive the elevator to reach the nearby floor according to the condition of the load of a lift car after being started, an internal contracting brake power source can be automatically cut out when the elevator reaches a door area, the door can be opened, and trapped persons can be rescued. The backup rescue system of the elevator is applicable to elevators with machine rooms and elevators without machine rooms, and cannot be influenced by arrangement of a shaft way, difficulty of rescue operation is low, rescue can be safely and reliably carried out under various conditions of elevator faults, and the backup rescue system of the elevator is simple in structure, easy to maintain, high in reliability, small in occupied area and low in cost.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator backup rescue system. Background technique [0002] At present, when the elevator stops between the two floors due to power failure, internal failure of the control cabinet or other line failures, the main rescue methods are: 1. Rescue by manually releasing the brake and sliding or turning the car. Professionals are required to operate, which consumes a lot of physical strength of rescuers. The operation is dangerous, and it is impossible to easily judge whether it is in the door area. And affected by the layout of the mainframe and machine room, this method cannot be used when the mainframe is placed below or without a machine room. 2. Use the power supply of the power outage cabinet for power outage rescue. It is necessary to add a special power outage cabinet for power supply, relying on the original control system, which can only deal with the situation of pow...
