Abstract
The utility model relates to a spare elevator safety device, belonging to the technical field of an elevator safety device, which can effectively avoid hidden safety risks caused by power outage to an elevator and has a simple structure. The spare elevator safety device comprises a back-up power supply device, a controller and a power supply detection circuit and is characterized in that the controller is respectively connected with the back-up power supply device, the power supply detection circuit and an elevator operation and control system, and the back-up power supply device is connected with an elevator power supply system through the power supply detection circuit; and the power supply detection circuit is used for detecting power output of the elevator power supply system to control whether the back-up power supply device supplies power to an elevator operation system and sending power outage signals to the controller, and when the controller receives the power outage signals, the controller controls the elevator operation and control system to implement last operating command, and then the back-up power supply device stops supplying power.
Description
Technical field
The utility model belongs to the elevator car safety technical field, relates in particular to a kind of elevator back up safety device.
Background technology
Elevator be a kind of be the vertical conveyor of power with the electrical motor, case shape gondola is housed, be used for tier building and take advantage of people or carrying goods.Elevator is that people's work and life provide a great convenience, but the power failure situation causes certain trouble for the use of elevator, and has caused certain potential safety hazard to the user.After having a power failure as: elevator, rethink the startup elevator, need personnel to open backup power, or manual remote control opens elevator, waste time and energy and gondola tenesmus phenomenon is arranged.
Summary of the invention
The utility model is exactly at the problems referred to above, and a kind of effectively prevent from the to have a power failure potential safety hazard that causes to elevator and elevator back up safety device simple in structure are provided.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises reserve electric supply installation, controller and power sense circuit, its structural feature controller links to each other with reserve electric supply installation, power sense circuit, elevator operation control system respectively, and the reserve electric supply installation links to each other with the elevator supply system by power sense circuit; Whether whether described power sense circuit have electric energy to export to control the reserve electric supply installation and power to the elevator operational system by detecting the elevator supply system, and send power cut signal to controller, after controller is received power cut signal, after control elevator operation control system executes last operating order, the reserve electric supply installation is stopped power supply.
As a kind of preferred version, controller described in the utility model adopts single chip machine controlling circuit.
The utility model beneficial effect
1, effectively prevents the potential safety hazard that has a power failure and cause to elevator
The utility model controller links to each other with reserve electric supply installation, power sense circuit, elevator operation control system respectively, and the reserve electric supply installation links to each other with the elevator supply system by power sense circuit; Whether whether described power sense circuit have electric energy to export to control the reserve electric supply installation and power to the elevator operational system by detecting the elevator supply system, and send power cut signal to controller, after controller is received power cut signal, after control elevator operation control system executes last operating order, the reserve electric supply installation is stopped power supply; Make elevator after power failure, can continue to move a period of time by the reserve electric supply installation, can make the elevator operation control system execute last operating order, make people arrive the floor of appointment, and open elevator by controller.Like this, after the power failure, people can not be stranded in elevator.In addition, because the reserve electric supply installation can only be kept the elevator operation of a bit of time, therefore, the utility model is set to: after operation control system executes last operating order, the reserve electric supply installation is stopped power supply; Avoided owing to reserve electric supply installation electric energy is used up the secondary potential safety hazard that produces.
2, simple in structure
The utility model comprises reserve electric supply installation, controller and power sense circuit; Member is few, connects simple.So the utility model is simple in structure.
Description of drawings
Clearer for technical matters, technical scheme and beneficial effect that the utility model is solved, below in conjunction with the drawings and the specific embodiments, the utility model is further elaborated.Should be appreciated that the specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model schematic block circuit diagram;
Among the figure, 1 is that controller, 2 is the reserve electric supply installation.
The specific embodiment
As shown in the figure, the utility model comprises reserve electric supply installation 2, controller 1 and power sense circuit, controller 1 links to each other with reserve electric supply installation 2, power sense circuit, elevator operation control system respectively, and reserve electric supply installation 2 links to each other with the elevator supply system by power sense circuit; Whether whether described power sense circuit have electric energy to export to control reserve electric supply installation 2 and power to the elevator operational system by detecting the elevator supply system, and send power cut signal to controller 1, after controller 1 is received power cut signal, after control elevator operation control system executes last operating order, reserve electric supply installation 2 is stopped power supply.
Described controller 1 adopts single chip machine controlling circuit.
Described reserve electric supply installation 2 can adopt the vast capacity storage battery.
Above content is to further describing that the utility model is done in conjunction with concrete preferred implementation; can not assert that concrete enforcement of the present utility model is confined to these explanations; for the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; can also make some simple deduction or replace, all should be considered as belonging to the definite protection domain of claims that the utility model is submitted to.
