Tube support structure for aircraft

摘要

A tube support structure for an aircraft includes: a parallel movement mechanism configured to support the tube movably in parallel; and an angle adjustment mechanism configured to support the tube angle-adjustably. The parallel movement mechanism includes: an eccentric sleeve, through which the tube passes, configured to adjust a position of the tube in a Z direction perpendicular to the X direction, and a Y direction adjustment mechanism configured to adjust a position of the eccentric sleeve in a Y direction perpendicular to the X direction and the Z direction. The angle adjustment mechanism includes: a first member configured to have a first curved surface and support the tube, and a second member configured to have a second curved surface with a shape corresponding to the first curved surface, have contact slidably with the first curved surface at the second curved surface, and support the first member by the second curved surface. Each of the first curved surface and the second curved surface is formed such that a cross-sectional shape in an XZ plane is a circular arc shape, and an angle of the tube is adjusted by sliding the first curved surface with respect to the second curved surface. Thus, a tube support structure for aircraft, which can suppress a preload, is provided.

主权项

1. A tube support structure for an aircraft, which supports a tube arranged to extend in an X direction inside an aircraft, the tube support structure comprising:
a parallel movement mechanism configured to support the tube and allow parallel movement of the tube; and an angle adjustment mechanism configured to support the tube and allow an angle of the tube to be adjusted; wherein the parallel movement mechanism includes: an eccentric sleeve, through which the tube passes, configured to adjust a position of the tube in a Z direction perpendicular to the X direction, and a Y direction adjustment mechanism configured to adjust a position of the eccentric sleeve in a Y direction perpendicular to the X direction and the Z direction, wherein the angle adjustment mechanism includes: a first member configured to have a first curved surface and support the tube, and a second member configured to have a second curved surface with a shape corresponding to the first curved surface, have contact slidably with the first curved surface at the second curved surface, and support the first member by the second curved surface, wherein each of the first curved surface and the second curved surface is formed such that a cross-sectional shape in an XZ plane is a circular arc shape, wherein the angle of the tube is adjusted by sliding the first curved surface with respect to the second curved surface, wherein the second member is joined to a structure body fixed to an airframe, wherein the Y direction adjustment mechanism is configured to shift a position of the second member with respect to the structure body in the Y direction, and wherein each of the first curved surface and the second curved surface has a shape that corresponds to a portion of an outer circumference surface of an imaginary cylinder with a central axis in the Y direction, the portion extending along the Y direction.
