Problems solved by technology

[0004] 1) There are many functional devices in the engine casing, which greatly limits the flexibility of the arm, and it is extremely inconvenient to extend the arm into the inside of the engine casing to move the rotor blades;
[0005] 2) Extend the arm into the engine casing to move the rotor blades. The working environment is harsh and there is a huge and unpredictable safety risk;
[0006] 3) It is necessary to arrange special staff to move the rotor blades. The coordination between this staff and the rest of the staff conducting the borehole inspection is poor, which affects the efficiency of the borehole inspection and prolongs the cycle of the borehole inspection

Abstract

The invention belongs to the technical field of engine rotor borescope inspection, and particularly relates to a rocking-turn structure which comprises a supporting seat and a rocking-turn rod. A supporting hole is formed in the supporting seat; the rocking-turn rod penetrates through the supporting hole and can swing and turn relative to the supporting seat; one end of the rocking-turn rod is a rocking-turn end, and the other end of the rocking-turn rod is a poking end which is bent.

Description

technical field [0001] The application belongs to the technical field of engine rotor borehole inspection, and in particular relates to a rocking structure. Background technique [0002] During the life cycle of an aircraft engine, it is sometimes necessary to perform a borescope inspection on the engine without losing its hair. To view the rotor blades distributed along the axial direction, each rotor blade needs to be moved to make each rotor blade rotate. [0003] At present, since the borescope holes on the engine casing facing the stator blades are small, and it is not suitable to open more holes on the part of the casing facing the rotor blades, it is difficult to directly inspect the rotor blades on the outside of the engine casing with tools. Toggle, when carrying out borehole inspection on the engine without hair loss, the staff mostly extend their arms through the inlet and outlet parts of the engine casing into the inside of the engine casing to turn the inner ro...
