Description
Skjøteelement for sprengstoffrør med ulike diametre. Joint element for explosive tubes with different diameters.
Den foreliggende oppfinnelse angår et skjøteelement for sprengstoffrør med ulike diametre. The present invention relates to a joint element for explosive tubes with different diameters.
Sprengstoffladninger for borehull og lignende pakkes vanlig-vis i rør som hensiktsmessig er lukket i begge ender. Slike rør har en viss standarddiameter og blir stappet ned etter hverandre ett for ett i borehullet, og det er da hensiktsmessig å bruke et skjøte-element mellom de forskjellige rør, så de som stappes inn i et borehull, vil danne en sammenhengende enhet. På det innerste rør i borehullet er der plasert en sprengkapsel. Dennes ledninger forløper utenfor de etterfølgende rør. Imidlertid er plassen for ledningene mellom rørene og veggen av borehullet relativt trang, så ledningen eller ledningene under ugunstige forhold vil kunne skades. Explosive charges for boreholes and the like are usually packed in tubes which are suitably closed at both ends. Such pipes have a certain standard diameter and are stuffed one by one into the borehole, and it is then appropriate to use a joint element between the different pipes, so that those which are stuffed into a borehole will form a coherent unit. An explosive capsule is placed on the innermost pipe in the borehole. Its wires run outside the subsequent pipes. However, the space for the wires between the pipes and the wall of the borehole is relatively tight, so the wire or wires under unfavorable conditions could be damaged.
Hensikten med den foreliggende oppfinnelse er å avhjelpe den nevnte ulempe som fører til at ledningen eller ledningene til sprengkapselen kan skades. Denne hensikt blir ved et skjøteelement av den innledningsvis angitte art ifølge oppfinnelsen oppnådd ved at det består av en rørformet hylse som er lukket i sin øvre ende med en skive, og fra hvilken der rager opp en annen hylse som er usymmetrisk anordnet i forhold til og har mindre diameter enn den først-nevnte hylse, og at skiven ved siden av den annen hylse har et hull for innføring av en sprengkapsel helt eller delvis i et sprengstoffrør med større diameter. The purpose of the present invention is to remedy the aforementioned disadvantage which leads to the wire or wires of the blasting cap being damaged. This purpose is achieved by a joint element of the type indicated at the outset according to the invention in that it consists of a tubular sleeve which is closed at its upper end with a disk, and from which another sleeve protrudes which is asymmetrically arranged in relation to and has a smaller diameter than the first-mentioned sleeve, and that the disc next to the second sleeve has a hole for inserting an explosive cap in whole or in part into an explosive tube with a larger diameter.
Oppfinnelsen vil bli belyst nærmere under henvisning til tegningen. Fig. 1 viser lengdesnitt av to rørladninger som har for-skjellig diameter og er sammenføyet innbyrdes ved hjelp av en skjøte-hylse. Fig. 2 viser perspektivisk en rørladning med større diameter, en skjøtehylse med sprengkapsel, en rørladning med mindre diameter, en skjøtehylse med sperreorgan og ytterligere en rørladning med mindre diameter. Fig. 3 viser elementene på fig. 2 innbyrdes sammenføyet og plasert i et borehull. The invention will be explained in more detail with reference to the drawing. Fig. 1 shows a longitudinal section of two pipe charges which have different diameters and are joined together by means of a joint sleeve. Fig. 2 shows a perspective view of a tube charge with a larger diameter, an extension sleeve with a detonating cap, a tube charge with a smaller diameter, an extension sleeve with a locking device and a further tube charge with a smaller diameter. Fig. 3 shows the elements of fig. 2 mutually joined and placed in a borehole.
På fig. 1-3 ses et rør 1 som er lukket i begge ender og inne-holder sprengstoff 2, f.eks. i form av pulver, sprengstoff på vanngel-basis eller lignende. Røret 1 har en diameter stort sett motsvarende diameteren av borehullet 3. På rørets øvre ende (fig. 1) er der trædd en rørformet hylse 4 som er lukket i sin øvre ende med en skive 5. Fra hylsen 4 rager der opp en annen hylse 6, som har mindre diameter enn hylsen 4. Hylsen 6 er plasert usymmetrisk i forhold til hylsen 4. I hylsen 6 er der innført en ende av et rør som er fylt med fortrinns-vis pulverformet sprengstoff 8. Skiven 5 har et hull 9 så en spreng-kapel 10 kan innføres helt eller delvis i røret 1. Sprengkapselen har to ledninger 11 og 12. In fig. 1-3 shows a pipe 1 which is closed at both ends and contains explosives 2, e.g. in the form of powder, explosives on a water gel basis or similar. The pipe 1 has a diameter largely corresponding to the diameter of the borehole 3. On the upper end of the pipe (fig. 1) there is threaded a tubular sleeve 4 which is closed at its upper end with a disk 5. From the sleeve 4 there protrudes another sleeve 6, which has a smaller diameter than the sleeve 4. The sleeve 6 is placed asymmetrically in relation to the sleeve 4. In the sleeve 6, an end of a tube is inserted which is filled with preferably powdered explosive 8. The disc 5 has a hole 9 so a detonating cap 10 can be inserted wholly or partially in the pipe 1. The detonating cap has two wires 11 and 12.
På fig. 2 ses en kombinert skjøte- og sperrehylse 13 som opp-viser en rørformet del 14 bestemt til å træs på den øvre ende av røret 7. Sperrehylsen har en øvre del bestående av et antall fliker 15. I denne øvre del træs der inn en ende av et rør 16 fylt med sprengstoff. In fig. 2 shows a combined joint and locking sleeve 13 which has a tubular part 14 intended to be threaded onto the upper end of the pipe 7. The locking sleeve has an upper part consisting of a number of tabs 15. In this upper part an end is threaded of a pipe 16 filled with explosives.
Skal et borehull 3 fylles med ladning, blir der i hullet, først innført ett eller flere rør med en diameter svarende til hullets, altså ett eller flere rør av 'samme diameter som røret 1. På det øverste av disse rør anbringes en hylse 4 med en sprengkapsel som helt eller delvis er innført i røret 4 gjennom hullet 9 i skiven 5. Når dette er gjort, settes røret 7 ned i hylsen 6, og deretter anbringes skjøtehylsen 13 på det øvre endeparti av røret 7, hvoretter den nedre del av røret 16 settes ned i den øvre del av skjøtehylsen 13. Ovenpå røret 16 kan så et ønsket antall rør med samme diameter som rørene 7 og 16 anbringes etter hverandre skiftende med skjøte-hylser 13. Den komplette ladning vil således få et utseende som vist på fig. 3. Takket være at ladningen er oppdelt i to deler, nemlig en nedre del med en diameter meget nær lik borehullets og en øvre del som har påtagelig redusert diameter og er plasert usym- If a borehole 3 is to be filled with a charge, one or more pipes with a diameter corresponding to that of the hole are first inserted into the hole, i.e. one or more pipes of the same diameter as the pipe 1. A sleeve 4 is placed on the top of these pipes with a blasting cap that is fully or partially inserted into the tube 4 through the hole 9 in the disk 5. Once this is done, the tube 7 is placed into the sleeve 6, and then the joint sleeve 13 is placed on the upper end part of the tube 7, after which the lower part of the tube 16 is placed in the upper part of the splicing sleeve 13. On top of the pipe 16, a desired number of pipes with the same diameter as the pipes 7 and 16 can then be placed one after the other alternating with splicing sleeves 13. The complete charge will thus have an appearance as shown in fig . 3. Thanks to the fact that the charge is divided into two parts, namely a lower part with a diameter very close to that of the borehole and an upper part which has a significantly reduced diameter and is placed asymmetrically
metrisk i forhold til den nedre del, fås rikelig plass for ledningene II og 12 opp til munningen av borehullet 3. Takket være denne rikelige plass unngås skader på ledningene 11 og 12. metrically in relation to the lower part, ample space is obtained for the wires II and 12 up to the mouth of the borehole 3. Thanks to this ample space, damage to the wires 11 and 12 is avoided.
De rør som er beskrevet i det foregående, kan være fremstilt av.hvilket som helst egnet materiale. Plast har dog vist seg mest hensiktsmessig. The tubes described above can be made of any suitable material. However, plastic has proven to be the most appropriate.
