Description
Oppfinnelsen angår en bergborerigg, og mer spesielt en bergborerigg hvor boreutrustningen er forsynt med en lyddempende kappe ifølge innledningen i patentkravet. The invention relates to a rock drilling rig, and more particularly a rock drilling rig where the drilling equipment is provided with a sound dampening jacket according to the introduction in the patent claim.
Ifølge en tidligere kjent lyddempende konstruksjon for en bergborerigg (se WO 00/39412) benyttes en stiv kappe som omgir boreutrustningen. Denne løsning har en rekke ulemper. Konstruksjonen er forholdsvis stiv. Dersom man under håndtering kommer i kontakt med berget, er det en fare for at den stive kappe skades ved sprekkdannelse. Vibrasjoner fra bergboremaskinen overføres til kappen og kan forårsake resonanser som motvirker lyddempningen, og som kan skade kappen. En annen ulempe er at åpningen mot operatøren er liten, og at det er meget vanskelig å se ved tilkopling av borstenger. According to a previously known sound-damping construction for a rock drilling rig (see WO 00/39412), a rigid jacket is used which surrounds the drilling equipment. This solution has a number of disadvantages. The construction is relatively rigid. If you come into contact with the rock during handling, there is a risk that the rigid casing will be damaged by cracking. Vibrations from the rock drilling machine are transferred to the casing and can cause resonances which counteract the sound attenuation and which can damage the casing. Another disadvantage is that the opening towards the operator is small, and that it is very difficult to see when connecting drill rods.
Ifølge en annen tidligere kjent løsning (se JP 5 079 271) er boremaskinmatingen dekket av en omgivende kappe og den fremre del av borstangen av en separat kappe. Denne lyddempende innretning synes forholdsvis komplisert og synes ikke å tillate boring med forlengelsesstenger. According to another previously known solution (see JP 5 079 271), the drilling machine feed is covered by a surrounding jacket and the front part of the drill rod by a separate jacket. This sound dampening device seems relatively complicated and does not seem to allow drilling with extension rods.
US 3 667 571 angår en lyddempende anordning for en bergborerigg. Bergboreriggen omfatter en bærer, en borebom som er forbundet med bæreren, en boremaskin som er bevegelig frem og tilbake langs en matebjelke som er forbundet med borebommen og en lyddempende kappe i form av to koaksiale sirkulære sylindrer som omgir matebjelken og bergboremaskinen. US 3,667,571 relates to a sound dampening device for a rock drilling rig. The rock drilling rig comprises a carrier, a drilling boom which is connected to the carrier, a drilling machine which is movable back and forth along a feed beam which is connected to the drilling boom and a sound-absorbing jacket in the form of two coaxial circular cylinders which surround the feed beam and the rock drilling machine.
Den foreliggende oppfinnelse har som formål å tilveiebringe en bergborerigg som gir god lyddempning, som gir gode terrengegenskaper fordi den er forholdsvis lett slik at god stabilitet oppnås, som tåler at man under manøvrering treffer f.eks. stein, og som er lett å betjene og tillater at man hele tiden kan overvåke boringen innbefattet forlengelse av borstenger. The purpose of the present invention is to provide a rock drilling rig which provides good sound attenuation, which provides good off-road properties because it is relatively light so that good stability is achieved, which can withstand hitting e.g. stone, and which is easy to operate and allows one to constantly monitor the drilling including the extension of drill rods.
Ifølge oppfinnelsen oppnås dette formål ved at bergboreriggen har de karakteristiske trekk som angitt i patentkravet. According to the invention, this purpose is achieved by the rock drilling rig having the characteristic features as stated in the patent claim.
En utførelse av oppfinnelsen skal beskrives i det følgende under henvisning til de ledsagende tegninger der An embodiment of the invention shall be described in the following with reference to the accompanying drawings therein
fig. 1 viser en bergborerigg ifølge oppfinnelsen, med visse deler fjernet for å vise deler innenfor kappen som omgir bergboremaskinen, fig. 1 shows a rock drilling rig according to the invention, with certain parts removed to show parts within the casing surrounding the rock drilling machine,
fig. 2 viser et forenklet riss av bare den omgivende kappe, fig. 2 shows a simplified view of only the surrounding mantle,
fig. 3 viser hvordan platene av den omgivende kappe er forbundet med hverandre og med en langsgående line, og fig. 3 shows how the plates of the surrounding mantle are connected to each other and with a longitudinal line, and
fig. 4-6 viser et antall platekonstruksjoner med tilføyd lyddempende lag. fig. 4-6 show a number of plate constructions with an added sound-absorbing layer.
Den på tegningen viste bergborerigg omfatter en bærer 1. En borebom 2 er forbundet med bæreren 1 som i det viste eksempel er et kjøretøy som er forsynt med larveføtter eller belter. En bomholder 21 er anordnet på bæreren 1 og er svingbar ved hjelp av en sylinder 22. Borebommen 2 er festet til bomholderen 21. Borebommen 2 manøvreres ved hjelp av sylindere 23, 24. Ved den fremre ende av borebommen 2 er det anordnet en matebjelke 3. Matebjelken 3 er svingbar i forhold til borebommen 2 ved hjelp av en sylinder 25. En bergboremaskin 4 er bevegelig frem og tilbake langs matebjelken 3. Rundt matebjelken 3 og bergboremaskinen 4 er det anordnet en lyddempende kappe 5. Kappen 5 omgir i det vesentlige fullstendig bergboreutrustningen. Unntaket er en langsgående åpning som er rettet mot posisjonen til operatøren på bæreren 1. Gjennom denne åpning, som ikke er vist på tegningene, kan operatøren overvåke boreprosessen og tilføye borstenger eller løsgjøre borstenger fra borestrengen 8 som er tilkoplet til bergboremaskinen 4. The rock drilling rig shown in the drawing comprises a carrier 1. A drilling boom 2 is connected to the carrier 1, which in the example shown is a vehicle that is equipped with crawler feet or belts. A boom holder 21 is arranged on the carrier 1 and is pivotable with the help of a cylinder 22. The drilling boom 2 is attached to the boom holder 21. The drilling boom 2 is maneuvered with the help of cylinders 23, 24. At the front end of the drilling boom 2 there is a feed beam 3 The feed beam 3 is pivotable in relation to the drill boom 2 by means of a cylinder 25. A rock drilling machine 4 is movable back and forth along the feed beam 3. Around the feed beam 3 and the rock drilling machine 4, a sound-absorbing jacket 5 is arranged. The jacket 5 essentially completely surrounds the rock drilling equipment. The exception is a longitudinal opening which is directed towards the position of the operator on the carrier 1. Through this opening, which is not shown in the drawings, the operator can monitor the drilling process and add drill rods or detach drill rods from the drill string 8 which is connected to the rock drilling machine 4.
Den lyddempende kappe 5 omfatter en bakre endedel 6 som ved hjelp av stenger 26 er festet til matebjelken 3. Den lyddempende kappe 5 omfatter også en fremre endedel 7 som også er festet til matebjelken 3, og i det viste eksempel en ramme 27 som ved hjelp av stenger 28 er festet til matebjelken 3. Den fremre endedel 7 er forsynt med en hylse 11 for kontakt med bakken eller grunnen 12 i hvilken boring skal finne sted. Borestrengen 8 kan beveges gjennom den fremre endedel 7 for boring i grunnen 12. Forbindingsmidler 9 i form av liner forbinder den fremre endedel 7 med den bakre endedel 6. I det viste eksempel er linene også festet til rammen 27. En fleksibel plate 10 er ved hjelp av øyeskruer 29 forbundet med linene 9. Platen er videre festet til den fremre endedel 7, den bakre endedel 6 og rammen 27. Ved hjelp av dette arrangement kan platen inndeles i seksjoner, slik at lett adkomst for service kan oppnås som vist på fig. 2. Plateseksjonene er videre forbundet ved hjelp av skruer og muttere 30. Den fleksible plate 10 bør passende veie minst 4 kg/m<2> for å oppnå passende lyddempning. The sound-absorbing cover 5 comprises a rear end part 6 which is attached to the feed beam 3 by means of rods 26. The sound-absorbing cover 5 also comprises a front end part 7 which is also attached to the feed beam 3, and in the example shown a frame 27 which by means of rods 28 is attached to the feeder beam 3. The front end part 7 is provided with a sleeve 11 for contact with the ground or ground 12 in which drilling is to take place. The drill string 8 can be moved through the front end part 7 for drilling in the ground 12. Connecting means 9 in the form of lines connect the front end part 7 with the rear end part 6. In the example shown, the lines are also attached to the frame 27. A flexible plate 10 is at by means of eye screws 29 connected to the lines 9. The plate is further attached to the front end part 7, the rear end part 6 and the frame 27. By means of this arrangement the plate can be divided into sections, so that easy access for service can be achieved as shown in fig . 2. The plate sections are further connected by means of screws and nuts 30. The flexible plate 10 should suitably weigh at least 4 kg/m<2> to achieve suitable sound attenuation.
Slik det er klart ut fra fig. 4-6, kan platen 10 være forsynt med et lett lag 31 av lyddempende materiale. Den fleksible plate 10 kan også bestå av flere plater som er plassert ved siden av hverandre, med eller uten mellomliggende lag av lyddempende materiale. Kappen 5 kan også være utformet med plater uten lyddempende materiale når kravet til lyddempning ikke er fullt så høyt. Som vist på fig. 2, kan man løsne linene 9 og As is clear from fig. 4-6, the plate 10 can be provided with a light layer 31 of sound-absorbing material. The flexible plate 10 can also consist of several plates which are placed next to each other, with or without intermediate layers of sound-absorbing material. The cover 5 can also be designed with plates without sound-absorbing material when the requirement for sound attenuation is not quite so high. As shown in fig. 2, you can loosen the lines 9 and
brette bort platen 10 slik at innsiden av kappen 5 blir tilgjengelig for service. fold away the plate 10 so that the inside of the cover 5 is accessible for service.
