Plane working ladder and plane maintenance device adopting same
The invention discloses a plane working ladder and a plane maintenance device adopting the same and relates to the technical field of plane working ladders. The plane working ladder comprises a working platform (1), an upper ladder frame (2), spring pins (3), a pedal (4), a lower ladder frame (5) and rotating shafts (8), wherein both the upper ladder frame (2) and the lower ladder frame (5) adopt steel pipe welding structures; the upper ladder frame (2) and the lower ladder frame (5) are connected and fixed to each other through two fixed rotating shafts (8) and two movable spring pins (3); the upper ladder frame (2) is not higher than the lower ladder frame (5); a steel pipe A and a steel pipe B which are connected with the fixed rotating shafts (8) and arranged on the upper ladder frame (2) have the same length. According to the plane working ladder disclosed by the invention, two purposes of one ladder during maintenance of a lower part of a plane can be realized, and switching between two different heights can be provided according to different working heights, so that both time and labor are saved, the storage space is reduced, and use is convenient. Meanwhile, the utilization ratio of equipment is increased and the manufacturing cost is reduced.
