Definitions

  • the invention relates to a repair- and/or patch ⁇ ing element in compliance with the introductory part of the claim 1 for vessels in water traffic, especially tankers transporting liquid cargo, to repair side and bottom damages located mostly on the water line or below it in order to prevent among other things sinking of the vessel and outflow of the cargo, and to minimize oil damages.
  • the repair and/or patching element according to the in- vention is very convenient in use and that the damaged area can be repaired by it quickly and above all tightly, whereupo almost all resulting effects of the leak are avoided and the vessel can continue its travel unaided even to its port of destination and only thereafter to the dock for repair operations.
  • Figure 1 is a horizontal section seen from above of the repair and/or patphing element according to the invention.
  • Figure 2 is a side elevation of ' the repair and/or patching element -according to the invention
  • Figure 3 is a cross section of the first means welded to the element in separate points
  • Figure 4 is a cross section of the other means possibly in the element for forming a continuous weld ⁇ ing seam.
  • the repair ' and/or patching element according to the in ⁇ vention has been laid to cover the hole B generated to the side A of the vessel.
  • the element 1 is in this example in the form of a relatively rigid rubber mat, so that it can properly be bent in compliance with the curved side surface of the vessel.
  • the mat 1 comprises two series of the first means 2 to be welded to their place* along the perimeter
  • a mattress bag 3 fastened for instance by vulcanization to its place inside.the in ⁇ nermost circle of the first means 2 welded at separate points to their place, to the side of the mat.1 to be placed against the side of the vessel, so that the said bag is filled by a medium - as gas, liquid or solidify ⁇ ing material - after the mat 1 has been fixed to its place by the first means 2 welded at separate points, whereby the bag 3 is pressed between the mat 1 and the side A of the vessel tightly over the damaged area closing possibly partially to the hole B in the side A; and the second means 4 for welding to their place pos ⁇ sibly located between the circles of the first means 2 to be welded at separate points to their place in order to form a continuous welding seam around the filled mattress bag 3 and the hole B.
  • the means 19 for filling the bag 3 can ad ⁇ vantageously be used for instance a gas cartridge dis- charged- at the desired moment and placed on the outer surface of the mat, and from which a flow conduct.1 goes through the mat 1 to the bag.
  • This kind of an adap ⁇ tation is not naturally the only possible.
  • the goal can also by achieved by supplying to the bag 3 for example compressed air, liquid or hardening polyurethane.
  • each of these first means to be welded at sepa- rate points to their place comprises a socket piece 13 open at least at its one end, the end part of which toward to object to be repaired is conically tapering " and which extends through the mat 1 and is fastened, for instance by vulcanization, steadily to the mat 1 ; a rotatable welding electrode 14 inserted coaxially in ⁇ side the socket piece 13, the end of which directed toward the object to be repaired is formed to correspond the inner surface of the tapering end part of the socket piece, and which for welding the socket piece 13 to its place .is pressed by the open end part of the socket piece 13 toward the surface of the object to be repaired; and possibly tightening means 15 and 16 to press the mat 1 and to the element possibly belonging other means 4 to be welded to their place tightly against the surface of* the object to be repaired.
  • the socket pie ⁇ ce.13 comprises at least one radially extending sup ⁇ port projection 17, preferably a flange, to keep the socket piece 13 steadily on the mat.1, so that the mat 1 is vulcanized to the outer surfaces ' of " both the socket piece 13 and the support projection.
  • the other end part of the socket piece far from "the object to be repaired extends beyond the mat.1 and is provided on its outer surface with a thread.18, whereupon a was ⁇ her 15 placed around the extending end part of the socket piece and over it to the thread.18 fitted ten- sion nut.16 can be used as tightening means 15 and 16.
  • Figure 4 is shown a cross section of the pre ⁇ ferred embodiment for the second means 4 to be welded to their place longitudinally on the level of the ele ⁇ ment- 1. After the welding of the first means 2 and pos- sible tightening by tightening means 15 and.16 these second selectively used means 4 are tightly pressed against the surface surrounding the damaged area.
  • these second means 4 to be welded to their place, by which a continuous welding seam is formed around the damaged area and the bag 3, comprise an elongated, for its full length to the mat for ins ⁇ tance by vulcanization fixed welding element 4 includ ⁇ ing a for its full length extending flow channel 5 for the medium conducting the welding current, so that this flow channel 5 is in a conductive contact to the core bar 6 of the welding element 4.
  • two bodies 7/pressed tightly to the walls defining the channel 5 are adapted to pass with the me ⁇ dium conducting the welding current in the flow channel 5.
  • the medium flow in the flow channel 5 is guided to stabilize the magnetic field and melting of the core bar, whereby as whole and faultless welding seam as possible is achieved.
  • the quantity and velocity of the medium flow is controlled hydraulically for ins- tance by a hydraulic pump and the above-mentioned body 7.
  • One part of the wall defining the flow, channel 5 is preferably made by " an .electrically conductive ma ⁇ terial strip 8, e.g. copper, connected conductively to the core bar.6 of the welding element.
  • an .electrically conductive ma ⁇ terial strip 8 e.g. copper
  • the body -7 pressed tightly to the walls defining , the flow channel 5 functions as- a contact member to press the material strip to a conductive contact with the core bar.6, so that the welding current is conveyed from the minim through ' the body 7 and/or the material strip to the core bar.6.
  • two parallel metal strips.10 and .11 have been placed to the side toward the object to be repaired at a small distance from each other, with their corresponding edges chamfered* accord ⁇ ing to the cross-sectional profile of the coating ' 12 of the core bar 6.
  • These metal strips.10 and 11 have been fixed to the mat 1 preferably by vulcanization,-
  • the me ⁇ tal strips 10 and 11 are welded both to each other and to the surface of the Object to be welded.
  • the purpose of the metal strips 10 and 11 is additionally to prevent the melting of the mat 1 during the welding process.
  • the flow channel has been connected according to the preferable embodiment of the invention through a suitable filling and discharging pipework to the medium source 9, whereupon the flow channel 5 is advantageously filled with medium before the welding process begins and discharged by suction with the desired velocity to adjust the welding speed when the welding current is switched on, so that the light arc generated between the welding object and the welding element follows evenly the flowing velocity of the medium and the route of conduction for the welding current to the core bar is- as short as possible* at every moment. Then can also be ensured, that- all the used conductive liquid medium can be' recollected.

Abstract

Un élément de réparation et/ou de colmatage en feuilles de forme ajustable sert en particulier à réparer des ruptures du côté et/ou du fond de navires-citernes transportant des cargaisons liquides. L'élément de réparation et/ou de colmatage se caractérise par le fait qu'il a: un premier organe (2), soudable de préférence à différents endroits, pour fixer l'élément (1) en place, un organe (3) que l'on remplit de gaz, de liquide ou d'un matériau durcissable, de préférence un matelas ou un sac annulaire attaché au côté de l'élément (1) que l'on veut placer sur le trou dans le côté (A) du navire, et possiblement un deuxième organe (4) à souder en place afin de former un cordon continue de soudage autour de l'organe (3) remplissable.
