Removable support interface for an annular turbomachine casing

A technology of annular casing and supporting interface, which is applied in the fields of annular turbine casing, aero-engine casing, and turbine, can solve the problems such as the inability of the turbine to remain in the suspended state, the wear of the screw thread part of the bolt, and the poor engine suspension performance. Quick and easy handling, good fixation, secure hanging effect

Problems solved by technology

However, during the lifetime of the turbine, the interventions required to handle the turbine are numerous, making these support interfaces necessary to be assembled and disassembled several times, which leads to severe wear of the bolt thread and the threaded portion of the pin, and therefore the presence of damage due to the support arms. Risk of poor engine suspension
Thus, even though these removable support interfaces meet the weight constraints imposed by the permanent support of the bosses on the annular casing, the means for securing these support interfaces to the annular casing do not hold the turbine securely for long periods of time. in suspension

Embodiment Construction

[0050] In this description, the terms "inner" and "outer" are used to denote positioning relative to the axis of rotation of the axial turbine.

[0051] figure 1 The supporting device 100 is shown cooperating with the annular housing 2 of the fan of the turbine T, for example the intermediate annular housing. The support device 100 comprises a frame 200, two support arms 210, 220 connected to the frame 200 and extending along respective horizontal longitudinal axes Xa, Xb. In position mounted on the support device 100 , and as described in more detail below, the annular housing 2 is thus supported by the support arms 210 , 220 via the two support interfaces 1 .

[0052] Displacement means (not shown) enable movement of each support arm 210, 220, in particular along its longitudinal axis Xa, Xb.

[0053] Such as figure 1 As shown, the support arms 210 , 220 are positioned substantially opposite each other and in such a way that there is sufficient space between the support arm...

Abstract

The invention relates to a removable support interface (1) for an annular turbomachine casing, comprising a coupling part (10) suitable for being mounted on the casing, and at least one attachment element (20a, 20b) for suspending the casing, orifices (30, 40) arranged in the coupling part (10), this interface being characterized in that it further comprises means for locking (5) the coupling part (10) to the casing (2), said locking means being positioned on the coupling part (10) and each comprising a clamp having two jaws hinged around a pivot connection, each clamp being movable from an open position in which a pin supported by the casing can be engaged and disengaged from one of said orifices (30, 40) and a closed position in which the pin is immobilized in this orifice (30, 40).

Description

technical field [0001] The invention relates to a support interface. More specifically, the present invention relates to a support interface for an engine casing, in particular an aeroengine casing such as a turbine, suitable for use during manufacture or handling of the engine. [0002] The invention also relates to an annular turbine casing configured to receive such a support interface. The invention also relates to an assembly comprising such an annular casing and such a support interface, and a turbomachine comprising such an assembly. Finally, the invention relates to a method of handling such a housing by means of such a support interface. Background technique [0003] The prior art includes documents FR-A1-3 041 376, WO-A1-2015 / 114276, WO-A1-2017 / 203139, FR-A1-3 051 833 and FR-A1-3 018 773. [0004] When handling a turbomachine, such as during an assembly or maintenance process, it is often necessary to support the turbomachine in an elevated position to allow eas...
