Description
Oppfinnelsen vedrører en innretning med strålerør for graving The invention relates to a device with jet pipes for digging
av grøfter ved nedgraving av en rørledning på havbunnen. of trenches when burying a pipeline on the seabed.
Det er kjent forskjellige typer av grøftegraveinnretninger. Different types of trench digging devices are known.
En type egner seg særlig godt for grunnmateriale som er av One type is particularly suitable for base material that is off
en granulert natur. Denne innretning innbefatter armkonstruk-sjoner hvormed kraftige vannstråler kan rettes i innretningens bevegelsesretning. Vannstrålene bevirker en fluidisering av grunnmaterialet, som så suges opp gjennom sugerør og tømmes ut i retning fra innretningen. På den måten kan man tilveie-bringe en grøft hvori rørledningen eller kabelen vil synke ned. a granular nature. This device includes arm constructions with which powerful jets of water can be directed in the direction of movement of the device. The water jets cause a fluidization of the base material, which is then sucked up through suction tubes and emptied in the direction from the device. In this way, a trench can be provided in which the pipeline or cable will sink.
I en innretning som er beskrevet ovenfor, benyttes vanligvis In a device described above, is usually used
en ramme som er utført og anordnet slik at den skrever over og samvirker med rørledningen eller kabelen. Strålerørarmene er stive forlengelser av rammen og rager ut i fra rammen under grunnivået. En slik innretning arbeider effektivt i løse grunnmaterialer. Det kan imidlertid lett oppstå skader, særlig på strålerørarmene, dersom det i innretningens bevegelsesbane befinner seg motstandsområder, såsom bergfremspring. a frame designed and arranged so that it overlaps and cooperates with the pipeline or cable. The radiator arms are rigid extensions of the frame and protrude from the frame below ground level. Such a device works effectively in loose base materials. However, damage can easily occur, particularly to the jet pipe arms, if there are areas of resistance, such as rock outcrops, in the device's path of movement.
Foreliggende oppfinnelse tar sikte på å redusere faren for skade på grøftegraverinnretningen. Ifølge foreliggende oppfinnelse foreslås det derfor en innretning med strålerør for graving av grøfter ved nedgraving av en rørledning på havbunnen hvilken innretning er kjennetegnet ved at strålerøret er montert slik i innretningen at det kan svinge fra en vertikal bruksstilling og bakover i forhold til innretningens bevegelsesretning, idet strålerøret er belastet til en bestemt verdi for derved å holde strålerøret i den ønskede vertikale bruk sstilling. The present invention aims to reduce the risk of damage to the trench digging device. According to the present invention, a device with a jet pipe for digging trenches when burying a pipeline on the seabed is therefore proposed, which device is characterized by the fact that the jet pipe is mounted in the device in such a way that it can swing from a vertical position of use and backwards in relation to the direction of movement of the device, the radiation tube is loaded to a certain value in order to thereby keep the radiation tube in the desired vertical position of use.
Med oppfinnelsen tilveiebringes det således en innretning The invention thus provides a device
hvor strålerøret holdes i en hovedsakelig vertikal stilling, f.eks. ved hjelp av en fjær, men har mulighet for å .vike unna dersom innretningen treffer på hårde bunnlag. where the radiation tube is held in a mainly vertical position, e.g. with the help of a spring, but has the option of moving away if the device hits hard bottom layers.
Strålerøret kan fordelaktig beveges til driftstillingen The jet pipe can advantageously be moved to the operating position
ved hjelp av hydrauliske anordninger. En fordelaktig ut-førelse har to strålerør anordnet i et V-arrangement. using hydraulic devices. An advantageous embodiment has two jet tubes arranged in a V-arrangement.
Dette vil gi en V-formet grøft som gir mulighet for optimal utnyttelse av den energi som er tilgjengelig for drift av innretningen. This will provide a V-shaped trench that allows for optimal utilization of the energy available to operate the device.
Oppfinnelsen skal beskrives nærmere under henvisning til tegningen som viser et utførelseseksempel. The invention shall be described in more detail with reference to the drawing which shows an exemplary embodiment.
Tegningen viser et frontriss av en utførelsesform av en graveinnretning ifølge oppfinnelsen. The drawing shows a front view of an embodiment of a digging device according to the invention.
Den viste utførelse innbefatter en ramme 1 som skrever over The embodiment shown includes a frame 1 which overwrites
en rørledning 2 som skal graves ned. Innretningen er lokalisert i forhold til rørledningen 2 ved hjelp av styreruller 3 som virker mot rørledningen og styrer innretningen langs rørled-ningen. Ikke viste drivanordninger bevirker at innretningen kan bevege seg langs rørledningen. Sideseksjoner 4 i rammen 1 virker som meier og understøtter innretningen på hver side av rørledningen. a pipeline 2 to be buried. The device is located in relation to the pipeline 2 by means of guide rollers 3 which act against the pipeline and guide the device along the pipeline. Drive devices, not shown, enable the device to move along the pipeline. Side sections 4 in the frame 1 act as screeds and support the device on each side of the pipeline.
Om så ønskes kan eventuelt ikke viste skruer erstatte side-seks jonene 4 og gi den nødvendige drivvirkning for innretningen. If desired, screws not shown can replace the side-six ions 4 and provide the necessary driving effect for the device.
I rammen 1 er det anordnet sugepumper 5 som trekker inn sjø-vann og pumper det ut gjennom strålerørarmene 6. Strålerør-armene er svingbart montert ved 7 og er anordnet i V-form, In the frame 1, suction pumps 5 are arranged which draw in seawater and pump it out through the jet pipe arms 6. The jet pipe arms are pivotably mounted at 7 and are arranged in a V shape,
slik det går frem av figuren. Denne V-form gar en V-formet grøft som gir mulighet for optimal utnyttelse av den energi som er tilgjengelig for drift av innretningen. På denne måten kan man oppnå den hurtigste arbeidshastighet for innretningen. as can be seen from the figure. This V-shape provides a V-shaped trench that allows for optimal utilization of the energy available for operating the device. In this way, the fastest working speed for the device can be achieved.
Strålerørarmene 6 svinges ved hjelp av ikke viste kraftanord-ninger. Disse kan f.eks. være hydrauliske arbeidssylindre. The beam tube arms 6 are swung by means of power devices not shown. These can e.g. be hydraulic working cylinders.
I den stilling som er vist holdes strålerørarmene under en viss / In the position shown, the jet pipe arms are held under a certain /
belastning, slik at dersom innretningen støter f.eks. på load, so that if the device hits e.g. on
et bergfremspring eller en annen hindring, så vil strålerør-armene svinge ut og vekk, og derved reduseres faren for skader på såvel innretning som rørledning. Alternativt kan strålerør-armene være fjærbelastet til arbeidsstillingen. a rock outcrop or other obstacle, the jet pipe arms will swing out and away, thereby reducing the risk of damage to both the device and the pipeline. Alternatively, the jet pipe arms can be spring-loaded to the working position.
Bak strålerørarmene 6 er det anordnet ikke viste sugerør hvori-gjennom det løsbrutte bunnmaterialet fjernes. Bunnmaterialet går ut gjennom ikke viste utløp og legges på siden av grøften. Behind the jet pipe arms 6 is arranged a suction pipe, not shown, through which the loosened bottom material is removed. The bottom material exits through outlets not shown and is placed on the side of the trench.
Med oppfinnelsen er det således tilveiebragt en grøftegrave-innretning som kan arbeide på en effektiv måte i forbindelse med ulike bunnforhold, samtidig som man har et innebygget sikkerhetsarrangement for å redusere faren for skade som følge av at innretningen støter på hindringer. With the invention, a trench digging device has thus been provided which can work in an efficient manner in connection with different bottom conditions, while at the same time having a built-in safety arrangement to reduce the risk of damage as a result of the device encountering obstacles.
