Definitions

  • the present invention relates to an equipment support intended to be mounted on a cylindrical surface. It allows in particular the cold mounting, without welding, of sprinkler rings for tanks containing flammable liquids, intended to spray water or foam to cool the walls of said tanks in the event of fire as well as the support of gangways, electrical cables and piping.
  • the invention finds its application in all factories where equipment must be supported by rigid walls of cylindrical elements, in particular petroleum refineries, petroleum production platforms and deposits of flammable products.
  • a device for fixing, in particular, sprinkler rings to tanks containing flammable products is described in patent FR 2 638 143.
  • This device comprises a fixing belt, designed to at least partially surround a tank of storage, at least one crown support fixed to said belt and extending radially outwards.
  • the fixing belt is in contact on one of its faces, over its entire length with the skirt of the tank, thus creating a large area of infiltration and water retention.
  • This device can be installed without welding on the tank, therefore without draining and degassing the tank. However, in many cases, this installation method is only temporary.
  • the object of the present invention is precisely to remedy these drawbacks. For this it offers an equipment support intended to be easily mounted on a rigid wall of a cylindrical element and creating corrosion risk areas as reduced as possible
  • the support of the invention comprises a plurality of consoles intended to support the equipment, a fastening belt provided with tensioning means, intended to be tightened in order to retain the consoles on the rigid wall.
  • the brackets are independent of the fixing belt and in that it further comprises spacers which in cooperation with the brackets are adapted to keep the fixing belt away from the wall rigid of the cylindrical element, over its entire length.
  • the spacer brackets are U-shaped profiled elements, comprising a base and two perpendicular branches, the faces of the ends of the branches resting on the rigid wall of the cylindrical element.
  • the brackets are profiles of the same shape as the spacer brackets extended perpendicular to their bases by support arms of the equipment.
  • the support arms comprise at least two parts that are mechanically connected in an adjustable manner.
  • the fastening belt has a flat face which rests on the bases of the spacers and brackets.
  • the stirrups and the brackets are provided on their bases with guides which limit their sliding relative to the fixing belt.
  • the branches of the spacing brackets and of the brackets include lights for the passage of the fastening belt.
  • the invention is also a reservoir, in particular of hydrocarbons, equipped with the support according to the invention, said support being intended to support a sprinkler ring provided with means for projecting liquid, placed around the tank and supplied by a pressurized liquid.
  • the invention comprises a device for mounting the support consisting of hooks which have a long straight part secured to a magnetic suction cup and a short curved part on the side opposite to said suction cup.
  • the brackets 2 and the stirrups 5 are arranged around the skirt 6 of the reservoir 1 and held in place by pressure against the skirt 6 under the action of the belt 3 which is tightened by means of tensioning means 4.
  • the belt 3, the brackets 2 and the stirrups being thus mounted, the belt 3 is spaced from the skirt 6 of the tank, which reduces the contact surface between the skirt 6 and the elements of the support. The areas where corrosion can develop are reduced.
  • the belt 3 is produced in several pieces which are easy to handle and to put in place.
  • a stirrup 5 of spacing in the shape of a U comprising a base 8 and two branches 9 and 10 perpendicular to the base 8, whose faces 11 and 12 ends are supported on the skirt 6 of the tank 1.
  • the belt 3 produced by means of a flat iron rests on the face 8 of the stirrup 5 and on the base 14 of the console 2, to keep these two parts tight against the skirt 6 tank 1.
  • the spacer 5 has a guide 19 and the console 2 a guide 18, which limit the sliding of the belt 3.
  • the branches of the U 9, 10 and 9bis and 10bis, respectively stirrups 5 for spacing and brackets 2 include lights 20, 22 and 21 and 23.
  • the belt 3 is made up of round profiled bars, which are arranged in the upper and lower parts of the lights, as illustrated in FIG. 8.
  • Figures 9 and 10 illustrate the particular application of the inventor's support, to support a sprinkler ring 30 of a tank 1 of flammable products.
  • the crown 30 provided with microgenerators 31 of foam is supplied with a mixture of water and foaming agent under pressure.
  • the foam sprayed onto the skirt of the tank constitutes a protective film of the skirt against the thermal radiation emitted by hydrocarbons in combustion around the tank. Thanks to the free space between the belt and the skirt, the film can develop without breaking and act as a protective screen.
  • the crown is made up of several sections to facilitate handling.
  • the brackets 17 are welded to the crown 30 by the welds 32.
  • the length of the support arm is adjusted as well as its angular positioning relative to the skirt of the tank.
  • the operations of welding the brackets 17 on the crown can be carried out before mounting on the tank.
  • the invention thus relates to a device for mounting the support illustrated in FIGS. 11 and 12, consisting of a hook 29 which comprises a long part 27 secured to a magnetic suction cup 26 and a short part 28 curved on the side opposite the suction cup 26.
  • brackets 2 and the stirrups 5 To set up the brackets 2 and the stirrups 5, these elements are suspended from the short portions 28 of the hooks, by passing said hooks through the holes 7 and 7bis. The assembly is then placed along the skirt 6 of the reservoir, against which it is held by the magnetic suction cup 26.
  • the belt 3 is put in place, tightened by action on the tensioning means 4.
  • the hooks 29 are then removed.
  • Another advantage of the invention is the possibility of welding the brackets 2 on the cylindrical surface for final mounting and of depositing the belt 3 and the spacers 5, these elements being reusable on another installation.
