The device comprises a guide rail, a first limit unit and a plurality of second limit units, wherein the guide rail is arranged on the outer side of an elevator car; the first limit unit is arranged at the guide rail in a sliding manner and is driven by a belt which drives a car door to open; the second limit units are arranged in an elevator well, and each of the second limit units is close to the elevator door of the corresponding floor; each of the second limit units corresponds to the first limit unit; when the car door opens in alignment with the elevator door of the first floor, the first limit unit is driven to move, so that the first limit unit and the corresponding second limit unit are mutually limited. Through the structure of the device disclosed by the invention, when the car door and the corresponding elevator door are opened, the elevator car can be prevented from abnormally moving up and down; the device for preventing the elevator car from moving during the opening of the elevator door has the advantages of being low in price and easy to mount, and needing no power to drive.
