Definitions

  • the present invention has for its object a constantheight vertical support device which can be putto use in particular for the purpose of supporting tanks such as nuclear reactor Vessels.
  • the device comprises a plurality of equidistant vertical pillars on each of which the bottom of the tank -is supported through the intermediary of a universal coupling or Cardan-type coupling, each pillar being constituted between its seating and the Cardan-type coupling by a succession of load-transmission members placed in series and which are compensated for expansion, which ensure the maintenance of the tank bottom at a constant level and which have a limited ilexibility in the radial direction in order to provide ⁇ for the radial expansions of the tank.
  • FIG. l is a vertical cross-sectional view of one pillar of the device
  • FiG. 2 is a View of the top portion of a pillar seen in cross-section along line II--II of FlG. l, and
  • FIG. 3 is a plan view on a smaller scale showing the arrangement of the pillars beneath the tank.
  • the bottom 1 of the tank 2 is supported by a plurality of equidistant and vertical pillars resting on a common bed-plate 3 which is anchored to the door, either directly or through the intermediary of jacks or like supports which ca-n be adjusted for height and which have not been illustrated ⁇ in the drawings.
  • the coupling between the bottom 1 of the tank and each pillar is effected by means of a pivotal mounting of the Cardan type.
  • the top portion of the pillar comprises a stirrup 4 pivotally mounted on a hollow shaft ice rup 4 and is centered in the cylindrical bore of a flange 13 which is fixed on the underface of the tank.
  • the stirrup 4 is extended downwardly by a tubular member 14, the bottom portion of which is fitted with a ⁇ flange 15 which is guided inside the central bore of a solepiece 16, this latter being supported on a footing-block which is integral with the bed-platet.
  • the stirrup 4 bears at 17 on a sleeve 18 centered in a cylinder 19 to which the said sleeve is rigidly fixed in the axial direction by means of a threaded portion 20;
  • the guide ring 22 bears at 23 on a ⁇ tuble 24 which surrounds ⁇ the member 14 and which in turn bears at 25 on a guide 26 which is rigidly fixed by means of a threaded portion 27 to a tube 2S.
  • the tube 23 is in turn rigidly secured at the top portion thereof by means of a threaded portion 29 to a guide 30 which bears at 31 on a tube 32, the said tube 32 resting at 33 on the sole-piece 16.
  • the cylinder 19 is centered in a ange 34 which is integral with a tubular sheath 35, the said sheath being welded at the bottom portion thereof inside a sleeve 36 which is secured to the sole-piece 16.
  • the guide 26 ensuresthat, by virtue of spherical bearings 37 and 38, the bottom portion of the assembly which is formed by the tubes 24 fand 28 ⁇ is guided over the tubular member 14 and inside the tube 32; similarly, the guide 39 ensures that,by virtue of spherical bearings 39 and 4l), the top portion of the assembly which is formed by the tubes 28 and32 is guided over the tube 24 and inside the sheath 35.
  • FIG. l shows that under theeifect of the loadwhich is supported by the pillar, the tubes 24 and 32 work in i of the bringing up to temperature lof the tank 2, the vari- 5 which is centered through the intermediary of bearingi
  • the centering of the pillar with respect to the bottom of the tank iseflected bymeans of a ball and socket or spherical knuckle-joint 12 which is integral with the stirations in the lengths of the tubes 24 and 32 in the direction of an upward lift of the tank are compensated by the variation in length of the tube28 in the direction of the downward displacement of the said tank, and it accordingly results therefrom that the distance between the bottom bearing-surface 33 of the tube 32 which rests on the sole-piece 1@ and the bearing surface 23 of the ring 22 which rests on the tube 24 remains substantially constant, irrespective in any case of the distribution of tem perature along the pillar.
  • This arrangement makes it possible to maintain the plane of bearing of the tank bottom on the pillars at a distance with respect to the floor which is substantially constant, both at the low temperatures which correspond to the shut-down of the installation as well as at the temperatures which correspond to the different operating conditions.
  • the initialadjustment of the height of the pillar with aview to ensuring on the one hand the perfect horizontality of the tank and on the other hand the uniform distribution of the load over all the pillars is carried into effect by screwing the sleeve ilS inside the cylinder 19.
  • the said cylinder il@ is secured against rotation by means of keys il which are brought to bear against the flange Eid which is integral with the tubular sheath 35.
  • the said keys nevertheless permit of axial sliding of the cylinder lli? inside the fiange 34 as and when variations of temperature occur.
  • FIG. 3 shows in plan and on a smaller scale
  • the five pillars provided are equidistant from each other and with respect to the vertical axis d of the tank; moreover, the distance between the two areas or faces of the tank which bear on the two sole-pieces 9 of one pillar is equal to the distance between two sole-pieces 9 which form part of two adjacent pillars.
  • the ra-dial expansions of the tank bottom produce identical elastic deformations of the pillars, by Virtue of a ⁇ pre-determined flexibility with which the sheath 35 of each pillar is endowed. Irrespective of the elastic deformation which is imposed upon the pillars, the areas or faces of the tank bottom which bear on the solepieces 9 of the pillars 4remain horizontal.
  • the heads of the pillars are brought back simultaneously towards the vertical axis of the tank; it should be noted that, whatever may be the value of the expansions or contractions of the tank bottom, the elastic restoring forces provided by the fiexible sheaths 35 contribute to maintaining the tank in the position in which this latter is centered on its vertical axis t).
  • the sheath 35 of each pillar is provided with two ribs 42 (as shown in FIG. 2), which increasethe moment of inertia of the sheath in the plane lat right ⁇ angles to the radial plane of expansion. These ribs are each engaged in the space between the depending legs of a stirrup member 43 which Ais integral with the Cardan frame '7.
  • spacing rings 44 and 45 are provided in the appropriate places.
