Abstract

This utility model discloses a single-arm, tilting-arm window cleaning machine, including a base. Four supporting legs are fixedly connected to the bottom of the base, and each pair of supporting legs shares a common track. Each supporting leg is equipped with a moving mechanism. A large gear is fixedly connected to the top of the base, and a control chamber is rotatably connected to the top of the large gear. A steering motor is fixedly connected to the control chamber, and the output shaft of the steering motor passes through the control chamber and is rotatably connected to it. A small gear is fixedly connected to the end of the output shaft of the steering motor, and the small gear meshes with the large gear. This utility model improves the lifting mechanism, increases the power transmission efficiency between the drive component and the winding component, and adds a protective structure to prevent dust and impurities from affecting transmission accuracy, preventing jamming and uneven speed during lifting of the suspended platform. The self-locking property of the worm gear ensures the safety of the operator.
