Description
Foreliggende oppfinnelse angår skjøteanordninger til bruk i forbindelse med sprengningsarbeider og angår spesielt skjøteanordninger mellom eksplosjonslunte og lavenergi puls-forplantningsrør. The present invention relates to splicing devices for use in connection with blasting work and in particular relates to splicing devices between an explosion fuse and a low-energy pulse propagation tube.
Lavenergi pulsforplantningsrør erstatter bruken av eksplosjonslunte ved visse anvendelser hvor støyen av eksplosjonslunte er uakseptabel eller bruken av eksplosjonslunte er farefull. Lavenergi pulsforplantningsrør består eksempel-vis av ""Nonel" rør ("Nonel" er et registrert varemerke) fremstillet av Nitro Nobel AB. Low-energy pulse propagation tubes replace the use of detonating fuses in certain applications where the noise of detonating fuses is unacceptable or the use of detonating fuses is dangerous. Low-energy pulse propagation tubes consist, for example, of "Nonel" tubes ("Nonel" is a registered trademark) manufactured by Nitro Nobel AB.
Hittil har det ikke vært mulig å skjøte eksplosivladnin-ger med lavenergi pulsforplantningsrør på samme måten som er tilfelle i forbindelse med eksplosjonslunte. Until now, it has not been possible to fuse explosive charges with low-energy pulse propagation tubes in the same way as is the case in connection with explosive fuses.
Alle forsøk som er gjort i forbindelse med kjente skjø-teanordninger har resultert i en upålitelig forplantning av antennelsen ved møtepunkter som omfatter mer enn én antennel-sesbane. All attempts that have been made in connection with known joining devices have resulted in an unreliable propagation of the ignition at meeting points that include more than one ignition path.
Mangelen på pålitelige skjøteanordninger har medførtThe lack of reliable splicing devices has led to
at ved normale sprengningsarbeider hvor det anvendes lavenergi pulsforplantningsrør som overflateforbindelsesledning er blitt utført i serier uten duplisering eller forgrening av anten-nelsesbanen, noe som innebærer at en hvilken som helst svikt i forplantningen eller initieringen av en bane av hvilken som helst årsak vil stoppe videre initiering langs banen. that in normal blasting operations where low-energy pulse propagation tubes are used as surface connection lines, they have been carried out in series without duplication or branching of the ignition path, which means that any failure in the propagation or initiation of a path for any reason will stop further initiation along the track.
Ved anvendelse av detonasjonslunte er det derfor alminnelig ved overflateledninger å duplisere initieringsbanene. When using detonation fuses, it is therefore common for surface lines to duplicate the initiation paths.
Foreliggende oppfinnelse går ut på tilveiebringelse av en ny, enkel skjøteanordning som kan anvendes både i serier og i parallell, slik at et antall lavenergi pulsforplantnings-rør kan skjøtes eller forbindes med en lengde eksplosjonslunte og derved danne en pålitelig skjøt eller et pålitelig møte-punkt for et antall initieringsfaner. The present invention consists in providing a new, simple splicing device that can be used both in series and in parallel, so that a number of low-energy pulse propagation tubes can be spliced or connected with a length of explosive fuse and thereby form a reliable joint or a reliable meeting point for a number of initialization tabs.
Ifølge oppfinnelsen tilveiebringes en skjøteanordning som omfatter et plasthus for en detonator og som har et i en ende åpent detonatorrør, samt anordninger for den åpne enden slik at en lengde av et lavenergi pulsforplantningsrør kan plasseres i tilstøtning med eller innskyves i den åpne enden av et detonatorrør i en fuktighetsavsperret forsegling, og hvor plasthuset har organer som gjør det mulig at en lengde av eksplosjonslunte kan holdes til anlegg mot den lukkede enden av detonatorrøret og i alt vesentlig vinkelrett på aksen av detonatorrøret. According to the invention, a joint device is provided which comprises a plastic housing for a detonator and which has a detonator tube open at one end, as well as devices for the open end so that a length of a low-energy pulse propagation tube can be placed adjacent to or inserted into the open end of a detonator tube in a moisture-proof seal, and where the plastic housing has means which enable a length of explosive fuse to be held against the closed end of the detonator tube and substantially perpendicular to the axis of the detonator tube.
Anordningen som er tilpasset for å muliggjøre at eksplosjonslunten kan holdes til anlegg mot detonatoren kan være en hvilken som helst egnet anordning, f.eks. en klemme støpt inn i plasthuset. En har kommet frem til an særlig egnet anordning for å sørge for at plasthuset har en åpning som forløper gjennom huset og i alt vesentlig vinkelrett på rørets akse. The device adapted to enable the detonating fuse to be held in contact with the detonator may be any suitable device, e.g. a clamp molded into the plastic housing. A particularly suitable device has been arrived at to ensure that the plastic housing has an opening which runs through the housing and is essentially perpendicular to the axis of the pipe.
Lavenergi pulsforplantningsrøret er fortrinnsvis forseglet inn i plasthuset koaksialt med detonatorrøret. Beskaffenheten av plastmaterialet som anvendes i plastrøret er ikke kritisk. Plastmaterialet er fortrinnsvis termoplastisk for å muliggjøre en rimelig fremstilling ved hjelp av sprøytestøpning. Egnede plastmaterialer er f.eks. LDPE, LLDPE, HDPE, PVC P.P., Surlyn og polyamid. (Surlyn er et registrert varemerke for en poly-olefin). The low-energy pulse propagation tube is preferably sealed into the plastic housing coaxially with the detonator tube. The nature of the plastic material used in the plastic pipe is not critical. The plastic material is preferably thermoplastic to enable a reasonable production by means of injection molding. Suitable plastic materials are e.g. LDPE, LLDPE, HDPE, PVC P.P., Surlyn and polyamide. (Surlyn is a registered trademark for a poly-olefin).
Enden av lavenergi pulsforplantningsrøret bør ikke plasseres inn i detonatorrøret så langt at enden av røret berører eksplosivladningen eller forsinkelseselementet i detonatoren. En fuktighetssperre mellom forplantningsrøret og huset kan fremstilles på en hvilken som helst egnet måte. F.eks., The end of the low energy pulse propagation tube should not be placed into the detonator tube so far that the end of the tube touches the explosive charge or the delay element in the detonator. A moisture barrier between the propagation tube and the housing can be made in any suitable manner. For example,
når forplantningsrøret plasseres i tilstøtning med enden av detonatorrøret kan plasthuset krympes rundt forplantnings-røret slik at det dannes en fuktighetssperre. when the propagation tube is placed adjacent to the end of the detonator tube, the plastic housing can be shrunk around the propagation tube so that a moisture barrier is formed.
Alternativt, når forplantningsrøret plasseres tett inntil detonatorrøret så kan detonatorrøret krympes på forplantnings-røret før innskyvning inn i plasthuset. Derved kan dannes et vanntett segl. Alternatively, when the propagation tube is placed close to the detonator tube, the detonator tube can be crimped onto the propagation tube before being pushed into the plastic housing. A watertight seal can thereby be formed.
Detonatoren kan enten være øyeblikkelig eller av forsin-kelsestypen. Skjøteanordninger tilpasset i øyeblikkelige detonatorer vil initiere på begge måter. (Fra lavenergi for-plantningsrøret til eksplosjonslunten eller motsatt). The detonator can either be instantaneous or of the delay type. Splicing devices adapted in instantaneous detonators will initiate in both ways. (From the low-energy pre-plant tube to the explosion fuse or vice versa).
Styrken av detonatoren er ikke særlig kritisk og beror på den typen eksplosjonslunte som anvendes. Vi har funnet for en normal eksplosjonslunte med 10 grains pr. meter at en detonator nr. 3 er egnet. Ulike typer lunter kan imidler-tid kreve enten en svakere eller en sterkere detonator. The strength of the detonator is not particularly critical and depends on the type of explosive fuse used. We have found a normal explosive fuse with 10 grains per meters that a No. 3 detonator is suitable. However, different types of fuse may require either a weaker or a stronger detonator.

Figurene 3 og 5 viser snitt langs linjen A-A på skjøte-anordningen vist på fig. 1, Figurene 2 og 4 viser snitt av en alternativ utførelses-form for skjøteanordningen. Examples of the invention are shown in the attached drawings where: Fig. 1 shows an outside view of the joint device.
