Device for fixing reactor modules to a test bench
View Patent ↗The invention relates to a suspension device of at least one reactor module to a test bench comprising at least one suspension arm, at least one upstream fixing assembly adapted to be fixed to a ceiling or wall of the test bench, at least one downstream fixing assembly adapted to be fixed to a reactor module, said suspension arm extending between two attachment ends adapted to be respectively fixed to the upstream fixing assembly and to the downstream fixing assembly, characterized in that said arm has a flexible median area whereof at least one cross-section dimension is less than the same cross-section dimension at the level of the attachment ends, the downstream casing comprising a fall-protection device.
1. A suspension device of at least one reactor module to a test bench comprising:
at least one suspension arm,
at least one upstream fixing assembly adapted to be fixed to a ceiling or wall of the test bench,
at least one downstream fixing assembly adapted to be fixed to a reactor module, said at least one suspension arm extending between two attachment ends adapted to be respectively fixed to the at least one upstream fixing assembly and to the at least one downstream fixing assembly,
wherein said at least one suspension arm has a flexible median area whereof at least one cross-section dimension is less than the same cross-section dimension at a level of the two attachment ends, said at least one suspension arm being a flat longeron whereof a height evolves progressively from the two attachment ends to the flexible median area.
2. The suspension device of at least one reactor module to a test bench according to claim 1 , wherein said at least one suspension arm comprises two suspension arms extending between a piece of the at least one upstream fixing assembly and a piece of the at least one downstream fixing assembly, the two suspension arms together ensuring isostatic fixing.
3. The suspension device of at least one reactor module to a test bench according to claim 2 , wherein the pieces of the at least one upstream fixing assembly and of the at least one downstream fixing assembly, on which the two suspension arms are fixed, are casings on lateral walls of which the two suspension arms are fixed by their attachment ends.
4. The suspension device of at least one reactor module to a test bench according to claim 3 , wherein the at least one upstream fixing assembly comprises:
a central casing on the lateral walls of which the two suspension arms are fixed by their attachment ends; and
two fixing casings fixed to said central casing by being connected on either side of the central casing, at a level of its lateral walls.
5. The suspension device of at least one reactor module with a test bench according to claim 1 , wherein the at least one upstream fixing assembly and the at least one downstream fixing assembly comprise at least one anti-peening device adapted to limit peening of a corresponding suspension arm of the at least one suspension arm.
6. The suspension device of at least one reactor module with a test bench according to claim 1 , wherein the at least one downstream fixing assembly comprises a fall-protection device.
7. The suspension device of at least one reactor module with a test bench according to claim 1 , wherein a suspension arm of the at least one suspension arm is bent.
8. The suspension device of at least one reactor module with a test bench according to claim 1 , wherein a suspension arm of the at least one suspension arm is convergent or divergent.
9. The suspension device of at least one reactor module with a test bench according to claim 1 , wherein the at least one upstream fixing assembly or the downstream fixing assembly comprises at least one anti-peening device adapted to limit peening of a corresponding suspension arm of the at least one suspension arm.
