Elevator for rescue and control method thereof

Abstract

The invention discloses an elevator for rescue and a control method thereof.The elevator comprises an escape exit, a first photoelectric sensor, a second photoelectric sensor, a first ladder stand assembly, a second ladder stand assembly, a landing door opening and closing assembly, a controller and an ARD emergency rescue device, and the controller is electrically connected with a car door opening and closing assembly, the first photoelectric sensor and the second photoelectric sensor; the ARD emergency rescue device is electrically connected with the controller, the lift car lifting assembly, the landing door opening and closing assembly, the computer terminal and the external power grid. The control method comprises steps S1 to S5. When power failure occurs, the lift car runs to the leveling position, the car door and the hoistway door are opened, and passengers escape; when the lift car cannot normally lift or the car door cannot be opened, the hoistway door suitable for passengers to escape is automatically opened, and the passengers are prompted to escape; in addition, the first crawling ladder assembly and the second crawling ladder assembly are both of a pure mechanical structure, the structure is simple, operation is convenient, and escape of passengers is facilitated.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a rescue elevator and a control method thereof. Background technique [0002] At present, passengers are often trapped due to sudden power failure in the process of taking conventional elevators; in order to avoid this situation, elevator companies generally add an emergency power supply to the elevator; the emergency power supply starts the elevator and makes the elevator run slowly to the nearest When the elevator fails, the emergency power supply cannot run the elevator, so that passengers cannot escape in time. SUMMARY OF THE INVENTION [0003] In view of the above deficiencies of the prior art, the present invention provides a simple and easy rescue elevator and a control method thereof. [0004] In order to achieve the above-mentioned purpose of the invention, the technical scheme adopted in the present invention is: [0005] An elevator for rescue is provided, which ...

Problems solved by technology

[0002] At present, passengers are often trapped due to a sudden power failure when taking a conventional elevator; in order to avoid this situation, elevator companies generally add an emergency power supply to the elevator; the emergency power supply starts the elevator and makes the elevator run slowly to the nearest leveling position, and then open the car door and hall door, so as to facilitate passengers to escape; however, when the elevator fails, the emergency power supply cannot run the elevator, resulting in the inability of passengers to escape in time
