Definitions

  • This invention relates to a releasable locking device, especially for use in lifting devices, in which a simple and reliable mechanism for the disconnection of heavy packages is es- sential, as for example when modules are being positioned in underwater installations. Further, the invention includes the application of memory metals in such devices.
  • a collar lock is formed to grip around a cylindrical portion in which there is arranged a collar at the free end portion thereof.
  • the collar lock is provided with a bore of a diameter adapted to the diameter of the collar, so that it can be slipped over the collar.
  • At a suitable distance from the end portion of the collar lock there are arranged in the bore two cylindrical countersunk hollows formed as steps of different depths .
  • the shallower countersunk hollow nearer to the end portion of the collar lock forms the locking hollow.
  • a sleeve, whose locking end portion has a cylinder-shaped bead, is positioned in the bore.
  • the locking end of the sleeve is split axially into many segments, so that the locking end of the sleeve consists of many "fingers", each of them with part of the cylindrical bead placed at its free end portion.
  • the sleeve Prior to connection, the sleeve is carried to a position, so that the beads of the sleeve have an axial position in the bore, which coincides with the deeper countersunk hollow positioned within the countersunk hollow which the beads lock into. Because this countersunk hollow is deeper, the fingers can pivot into it when they are slipped over the collar. By the spring force of the fingers the beads at the inner portion of the sleeve (and fingers) will be positioned behind the collar. The collar coupling housing is then carried axially relative to the sleeve, so that the beads at the outer portion of the sleeve are positioned in the countersunk hollow, in which the beads are locked and thereby prevented from moving out of the collar.
  • a load-carrying hook is connected at one end to a housing by means of a hinge.
  • a locking spindle In a bore in the housing is positioned a locking spindle.
  • the housing is provided with an internal threaded portion for attachment to the lifting equipment.
  • the locking spindle which can be displaced axially in the bore of the housing, is arranged to be placed, in its locked position, in a locking hole in the hook.
  • the drop-out hook coupling is opened in that the locking spindle is displaced out of the hole of the hook, after which the hook may pivot about the hinge and release the load hanging on the hook.
  • Both types of quick release couplings can be manoeuvred mechanically, hydraulically or pneumatically.
  • connection links In work under water the connection links must be operated by a diver or a ROV (Remote-Operated Vehicle).
  • ROV Remote-Operated Vehicle
  • the types of quick release couplings can be operated from the sea surface, by for example a hydraulic connection from an aggregate on a ship to an actuator in the coupling.
  • the object of the invention is to remedy the negative aspects of existing equipment, the new technique making use of a novel coupling of the multi-dog type and power elements , in which a phase change in a memory metal is used indirectly to operate a locking element of the coupling, which enables the use of a simple and functionally reliable remote control equipment.
  • a coupling of the multi-dog type according to the invention has, for example, an outer part (the female part) with a bore, in the cylindrical surface of which there is arranged one or more annular countersunk hollows.
  • the coupling parts are also provided with a securing device for connection to a load or a piece of lifting equipment.
  • the inner part (male part) of the coupling is formed so, that a cylindrical part of it can be inserted into the bore of the outer part.
  • this cylindrical part are arranged two or more axial slots, with a locking dog being suspended resiliently on a hinge shaft in each slot, so that within a limited sector it may pivot in and out from/towards the centre line of the coupling.
  • the locking dogs In a loaded state the locking dogs will rest on the bottom of the axial slot, whereas in the unloaded state they will spring back and have a clearance to the bottom of the axial slot.
  • the clearance can be adjusted through, e.g., an adjustment screw located in the locking dog and tightening against the hinge shaft.
  • a locking body may be inserted into a bore, in between the locking dogs when they are in a locked position pivoted outwards .
  • the locking body When the two main parts of the coupling are being brought together, the locking body is positioned outside the sector, within which the locking dogs may pivot, so that the locking dogs can adopt a position pivoted inwards.
  • the inner part of the coupling may thereby be inserted into the outer part of the coupling.
  • the locking dogs pivot outwards and engage the countersunk hollows of the outer part.
  • the locking body is then inserted between the locking dogs and prevents them from pivoting back in towards the centre of the coupling when the coupling is loaded. Thereby the coupling forms a fixed mechanical connection. Releasing of the coupling can take place when it is unloaded, in that the locking body is carried out of the area of the pivoting sector of the locking dogs.
  • the locking dogs may then be pivoted inwards, out of the countersunk hollows of the outer coupling, and the inner part of the coupling may be pulled out of the outer part.
  • the locking element is suspended between two types of springs, which pull or push the locking element in opposite directions.
  • a spring may consist of several springs or spring systems.
  • the force of a conventional spring will in- fluence the locking element in a direction towards the locked position, whereas the force of a memory metal spring will work in the opposite direction.
  • the memory effect of the memory metal may be explained as the material appearing in two different structural phases.
  • the material In its cold state the material has an easily mouldable martensite structure, with a yield strength of e.g. about 70 MPa, and above the transformation limit an austenite structure with a yield strength of e.g. about 210 MPa.
  • the temperature of transformation between the martensite and austenite structures may be kept in the range from -100 °C to +100 °C.
  • Memory metals are also known, which may have two positions, depending on the temperature, without mechanical influence, i.e. the metal adopts one geometry under the influence of heat and another geometry when the metal is cooled. Memory metals are well known in themselves and are commonly available, and therefore are not an object of this patent application.
  • the ordinary spring which affects the locking body and has a greater tension than that of the memory metal springs in their cold state, will overcome the force of the memory metal springs and push the locking body into the locked position.
  • the coupling is to be re- leased in the unloaded state, the memory metal is heated. The structure is then changed to the mechanically strong austenite state. The increased force of the memory metal springs is sufficient to overcome the force of the ordinary spring. Thereby the locking body is carried away from the locking position, so that the dogs can pivot in towards the centre of the coupling in order, thereby, to release the mechanical connection between the coupling parts.
  • a further development of the invention consists in the arrangement, at the coupling, of a manoeuvring/battery pack which is connected to the memory metal springs.
  • This unit can be controlled from the sea surface by the use of known radio/sonar technique. Warm liquid and/or chemical energy in the form of reaction heat from two or more materials can also be used as a heat source.

Un ou plusieurs raccordements (2,3) sont effectués dans l'équipement de levage (4) ou entre l'équipement de levage (4) et la charge (1). Le raccordement est bloqué ou ouvert directement ou indirectement par changement de positionnement ou de rotation de l'élément de blocage (13). Le changement de positionnement ou de rotation de l'élément de blocage (13) entre les positions bloquées et débloquées intervient directement ou indirectement par variations structurales d'un ou de plusieurs métaux. La variation structurale peut être télécommandée sans fil, par utilisation d'équipement auxiliaire de type connu. L'invention concerne en outre l'utilisation de métal à mémoire de forme pour changer la position du corps de blocage (13) entre une position bloquée et une position non bloquée dans un raccordement comme décrit ci-dessus.
