Definitions

  • the present invention relates to an arrangement comprising a vertically movable element under the effect of thermal expansions or contractions, and a fixed frame supporting a mass connected in overhang to the movable element, the mass being supported by a device support.
  • the object of the present invention is to provide an arrangement ensuring the rigid support of such cantilevered masses, the displacements of which follow more rigorously the displacements of the vertically movable element, composed of elements which are not subjected to flexural stresses, but only tensile or compressive stresses.
  • the arrangement according to the invention is characterized in that its support device comprises a first arm articulated on a point of the vertically movable element, a second articulated arm, on the one hand on the end of the first arm on the side of the mass, which is placed sliding on the articulation of the first arm and the vertically movable element, on the other hand on the fixed frame, and a third articulated arm, on the one hand on the end of the first arm of the side of the vertically movable element, on the other hand on the fixed frame at a point at a different level from that of the point of articulation of the second articulated arm.
  • This device may further comprise in each of its variants a support for the mass exerting on it a constant upward traction force.
  • the vapor collector 1 is fixed relative to a partition 2, formed of tubes 2A and connecting fins 2B, of a boiler combustion chamber, so that its connecting tubes 3 with the tubes of a superheater 4 are not subjected to stresses due to differential expansions of the manifold and of the partition.
  • the collector is fixed on a cross-member 5 pivotally hooked at point A to the partition 2.
  • a second support point of the cross-member is formed by the articulation B, at its other end, on which it is pressed to slide.
  • the articulation B belongs to a system formed by the articulated arms 6, 7 and 8.
  • the arms 7 and 8 are connected with the possibility of pivoting and sliding at point C, integral with the partition 2, below point A.
  • the arms 6 and 8 are fixed respectively with the possibility of pivoting on the vertical fixed frame 9 at points E and D.
  • FIG. 2 shows a support device where the arm 6 is inclined relative to the horizontal by an angle ⁇ , the other arms being unchanged with respect to Figure 1, so that the vertical displacement of point B, subject to describe a circle of radius BE, that is to say substantially proportional and less than that of point C, and no longer equal to that of the latter.
  • this allows to respond to the fact that during thermal expansions point C of the partition generally descends more than point A.
  • the end of the cross-member 5 is fixed to a constant support element with springs 11, which makes it possible not to dimension the arm system only to support a fraction of the total load, and therefore reduce the vertical load transmitted to the partition 2 formed by the vaporization tubes.
  • the articulation arms are not subjected to any bending stress, but only to tensile or compression stresses, which makes it possible to give them cross sections significantly less than those of arms of known devices, working in flexion.
  • the invention applies in particular to the suspension of a manifold on the wall of the combustion chamber of a boiler or of a steam generator but could also be applied to the suspension of other devices, such as burners.
