Pile foundation perpendicularity detector

The utility model provides a pile foundation perpendicularity detector which comprises an installation plate and a detection mechanism. The accommodating box is vertically and fixedly connected to the lower surface of the mounting plate; the detection mechanism comprises a first motor, the first motor is vertically and fixedly connected to the top of the inner wall of the containing box, an output shaft of the first motor is vertically and fixedly connected with a connecting rod, and the bottom end of the connecting rod rotatably extends to the position below the containing box. According to the pile foundation perpendicularity detector, after the infrared distance meter is moved to the detection position of a pile foundation, the connecting rod can be driven to rotate through the first motor, the connecting rod drives the infrared distance meter to do circular motion in the rotating process, and then whether the end face of the pile foundation inclines or not is detected through the infrared distance meter;
