Abstract

The present invention relates to a locking member ( 24 ) for a device for attaching ring sectors to an aircraft turbomachine casing, said member comprising two longitudinal clamping branches ( 28, 30 ) extending rearward and connected at their rear ends by a transverse connecting branch ( 32 ), their front ends being intended, between them, to press at least one ring sector ( 16 ) against at least one casing element ( 14 ). According to the invention, the member ( 24 ) further comprises means ( 42 ) allowing it to be grasped, these means being arranged such that they project rearward from the transverse branch ( 32 ).

Claims (11)

1. A locking member for a device for attaching ring sectors to an aircraft turbomachine casing, said member comprising two longitudinal clamping branches extending rearward and connected at their rear ends by a transverse connecting branch, their front ends being intended, between them, to press at least one ring sector against at least one casing element,

which member further comprises means allowing it to be grasped, these means being arranged such that they project rearward from said transverse connecting branch.

2. The locking member as claimed in claim 1 , wherein said means allowing the member to be grasped comprise an extension projecting longitudinally rearward from said transverse connecting branch, and at least one recess made in said extension, this recess forming an abutment surface directed toward said transverse connecting branch.

3. The locking member as claimed in claim 2 , and which forms an angular sector of an annular locking device.

4. The locking member as claimed in claim 3 , wherein said projecting extension extends, in a circumferential direction, over all or part of said angular sector.

5. The locking member as claimed in claim 3 or claim 4 , wherein each recess extends, in the circumferential direction, over all or part of said projecting extension.

6. The locking member as claimed in claim 5 , and which comprises two grooves each forming a recess in said projecting extension, said grooves opening in opposite directions of a radial direction in which said two longitudinal clamping branches are spaced apart.

7. A device for attaching ring sectors to an aircraft turbomachine casing, comprising casing elements formed with first rear circumferential rims to which second rear circumferential rims of the ring sectors are applied, wherein the attachment device further comprises a plurality of locking members as claimed in any one of the preceding claims, fitted onto said first and second circumferential rims in order to keep them pressed firmly against one another.

8. A turbine for an aircraft turbomachine comprising a device for attaching ring sectors as claimed in claim 7 , or at least one locking member as claimed in any one of claims 1 to 6 .

9. An aircraft turbomachine comprising a turbine as claimed in claim 8 or a device for attaching ring sectors as claimed in claim 7 or at least one locking member as claimed in any one of claims 1 to 6 .

10. The turbomachine as claimed in claim 9 , and which is a turbojet or a turboprop engine.
