Devices for aircraft maintenance

Abstract

The invention discloses an airplane repairing device which comprises a base frame. Idler wheels are arranged at the bottom of the base frame. A working platform is arranged at the top of the base frame. A pipe body is erected on the edge of the working platform. The middle portion of a supporting rod is sleeved with the pipe body through a bearing. A rotary handle is arranged at one end of the supporting rod, and a first gear is arranged at the other end of the supporting rod. A supporting frame is further arranged on the base frame. An annular piece is arranged on the end face of a second gear. An annular sliding rail is arranged on the supporting frame. The annular piece is rotationally connected in the annular sliding rail. The second gear is engaged with the first gear. A screw hole is formed in the center of the second gear. A threaded rod is connected in the screw hole in a screw joint mode. The top end of the threaded rod is used for supporting the central area of the working platform. At least three stand columns are evenly arranged on the edge of the working platform. A plurality of sleeves are arranged on the base frame. The stand columns are movably sleeved with the sleeves in a one-to-one correspondence mode. By the adoption of the airplane repairing device provided by the invention, the proper working height can be achieved, and repairing work is more convenient.

Description

technical field [0001] The invention relates to aircraft maintenance technology, in particular to a device for aircraft maintenance. Background technique [0002] During aircraft maintenance or maintenance, due to the relatively tall fuselage, maintenance personnel need to stand on a movable device for aircraft maintenance to maintain the aircraft. Generally, the device for aircraft maintenance includes a pedestal, a pedestal The bottom of the base frame is provided with rollers, and the top of the base frame is provided with a working platform, on which maintenance personnel stand to perform repair or maintenance operations on the aircraft. The application number is 200920183207.1, the publication date is 2010.6.23, and the patent titled "A Ladder for Aircraft Maintenance" provides such a device for aircraft maintenance. [0003] The disadvantage of the existing technology is that when the maintenance personnel are on the working platform to perform maintenance or maintena...

Problems solved by technology

[0003] The disadvantage of the existing technology is that when the maintenance personnel are on the working platform to perform maintenance or maintenance operations, some more precise operations have certain requirements on the posture of the maintenance personnel, such as requiring the head or hands to be in a specific position, This requires the working platform to stay at a specific height position and horizontal position, but the working platform in the prior art can only be adjusted horizontally by rollers, and does not have a height adjustment function, which makes some maintenance operations for maintenance personnel more inconvenient
