The invention discloses an automatic leveling rescue device and method for an elevator during power failures. The automatic leveling rescue device for the elevator during the power failures comprises an elevator power source main switch, an elevator lift car door opener and a tractor brake device. The automatic leveling rescue device for the elevator during the power failures further comprises a power-failure leveling control unit, an electric energy storage device, a leveling signal unit and an elevator power grid outage signal unit, the power-failure leveling control unit is connected with the elevator power source main switch, the tractor brake device, the electric energy storage device, the elevator lift car door opener and the leveling signal unit, and the electric energy storage device is further connected with the tractor brake device, the elevator lift car door opener and the elevator power grid outage signal unit. By means of the technical scheme, people can be automatically released in a leveling mode, and the automatic leveling rescue device is easy to implement, economical and practical.
Description
technical field [0001] The invention relates to an elevator leveling device and method, in particular to an elevator power failure automatic leveling rescue device and method Background technique [0002] At present, there are two ways to deal with the sudden power failure of the elevator: one is to use the emergency power supply. When the power grid suddenly loses power, the emergency power supply replaces the external power grid of the elevator to the whole system of the elevator, including the traction machine, control cabinet, car control panel, and outbound calls. Power supply, so that the elevator continues to run to the nearest leveling position and then open the door to prevent the car from being closed; off people. [0003] The above two methods, the first one does not require people to come to the scene to open the door immediately, which is convenient and quick, but it needs to provide a large power supply and other safety devices that can drive the elevator, whi...
