Abstract

The invention relates to a method for handling a rectifier of a turbojet of an aircraft, the rectifier having an axis defining the asymmetry thereof, said method comprising a step of placing the rectifier on the rollers of a supporting structure, the structure and the rollers thereof being arranged such that the axis of the rectifier is inclined at a non-null acute angle in relation to the horizontal, and a step of controlling, maintaining, assembling, handling, storing, deburring and/or cleaning the rectifier, during which the rectifier is pivoted about the axis thereof. The invention also relates to a trolley for handling a rectifier for an axial turbojet, said trolley comprising at least two of the lower rollers that have axes inclined in relation to the horizontal of said angle and at least one upper roller, the axis of which is inclined in relation to the vertical of said angle.

First claim

The invention claimed is:

1. A trolley for handling a rectifier for an axial turbine engine, the trolley comprising:
a structure for supporting the rectified, the structure having an arrangement of beams on which are positioned rollers for supporting the rectifier, wherein the rollers comprise:
at least two lower rollers whose axes are inclined at a non-zero acute angle relative to a horizontal direction and one upper roller whose axis is inclined at said non-zero acute angle relative to a vertical direction;
wherein the arrangement of beams forms the shape of the letter Y inverted, with an upper beam carrying the upper roller and two lower beams carrying the lower rollers, the upper beam defining an axis of symmetry of the structure;
wherein the upper beam and the lower beams are coplanar and arranged in a plane which is inclined of said non-zero acute angle relative to the vertical direction.

2. The trolley according to claim 1 , wherein the axis of the upper roller is parallel to the plane of the beams and a distance from the axis of the upper roller to the plane of the beams is adjustable.
