Abstract

This utility model relates to the field of elevator guide rail testing technology, and discloses an elevator guide rail verticality calibration device, including a fixed frame, a through-beam photoelectric switch, a calibration box, a moving component, a displacement sensor, and a main control unit. The fixed frame is connected to the elevator guide rail and has a laser source mounted on it. The calibration box is also connected to the elevator guide rail and contains a target component that corresponds to the laser source in the direction of gravity. The through-beam photoelectric switch includes a transmitting end for emitting photoelectric signals and a receiving end for receiving photoelectric signals. The transmitting end is mounted on the fixed frame, and the receiving end is located inside the calibration box, with the transmitting end corresponding to the receiving end in the direction of gravity. The moving component is located inside the calibration box and is used to adjust the positions of the target component and the receiving end in a first direction and a second direction. The displacement sensor is mounted on the moving component. This device improves measurement accuracy and precision, and has a high degree of automation.
