A device and a method for detecting elevator rope elongation, and an elevator are disclosed. An elevator rope is connected to a rope head device and an operating device in an elevator, and the device for detecting elevator rope elongation includes: one and more brackets connected to an elastic reset member in the rope head device, a coupling member connected to at least one of the brackets and configured to be driven into a trigger position by the at least one bracket when the displacement of the elastic reset member exceeds a threshold value due to reduction of compression amount, and a trigger connected to the coupling member and configured to be triggered to generate a trigger signal when the coupling member is driven into the trigger position. The present disclosure can be widely applied to detect the elevator rope elongation condition in many types of elevator equipment.
