Abstract

The invention discloses a deflector rod device for an aircraft engine fan blade, which comprises a handle, a front pipe section, a rear pipe section, a bracket A, a bottom plate A and a driving mechanism, wherein the handle is connected with one end of the front pipe section; an overrunning clutch is arranged at the joint of the handle and the front pipe section, and is used for limiting anticlockwise rotation of the handle; the bracket A is arranged at a position, near the joint, of the front pipe section, and is fixed on the bottom plate A via a dovetail-type chute; the other end of the front pipe section is connected with one end of the rear pipe section; and the other end of the rear pipe section is connected with the driving mechanism via a connecting shaft. The deflector rod device has the advantages of being simple in structure, easy to disassemble, and convenient for long-distance toggling of the aircraft engine fan blade.

Description

technical field [0001] The invention relates to the technical field of routine inspection and maintenance of aero-engines, in particular to a fan blade lever device of an aero-engine. Background technique [0002] A special maintenance tool for the fan blade of an aero-engine similar to the present invention is found after retrieval. During routine inspection and maintenance engine inspection, one person needs to manually rotate the high-pressure rotor outside, and one person observes the blades at the front end of the engine. Two people are required to cooperate to complete the inspection work. The adjustment is very inconvenient and requires the help of a ladder, which is dangerous and wasteful. manpower. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art and provide an aeroengine fan blade lever device with simple structure, easy disassembly and convenient remote operation. [0004] The object of t...
