Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anti-collision ladder frames, in particular to an anti-collision ladder frame based on ultrasonic ranging. Background Art
[0002] Due to the external shape of the aircraft, a ladder is mostly used when the aircraft is repaired or maintained. The ladder is convenient for aircraft maintenance personnel to repair and maintain the aircraft. However, when the aircraft maintenance ladder is moved, there is no relevant personnel on the upper part of the aircraft maintenance ladder, and the people on the ground cannot observe the upper part of the aircraft maintenance ladder clearly. When the aircraft maintenance ladder is moved, the upper part of the aircraft maintenance ladder may accidentally collide with the aircraft, which may cause damage to the outer surface of the aircraft, and may pose a hidden danger to the safe flight of the aircraft. At the same time, when the aircraft maintenance personnel move the aircraft maintenance ladder, they may neglect to observe the lower part of the ladder. When the aircraft maintenance ladder is moved, the ladder may hit the objects on the ground, which not only affects the movement of the ladder, but also may cause damage to the ladder or the objects on the ground.
