Abstract

Rock drilling rig comprising a carrier (1), a drill boom (2) connected with the carrier, a rock drilling machine (4) movable to-and-fro along a feed beam (3) connected with the feed boom and a sound dampening casing (5) substantially entirely surrounding the feed beam and the rock drilling machine, in which the sound dampening casing (5) comprises a rear end part (6), a fron end part (7) throuh which a drill string (8) connected to the rock drilling machine (4) can be moved, means (9) connecting the rear end part (6) and the front end part (7) with each other, a flexible sheet (10) which weights at least 4 kg/m<2> connected with the rear (6) and front (7) end parts and said means (9) and that the front end part (7) is provided with a sleeve (11) for contact with a ground (12) in which drilling is to take place.

Description

annan 517 918 §:=2::='-.-' 11” Den på ritningen visade borriggen innefattar en bärare 1. En borrbom 2 är ansluten till bäraren l som i det visade exemplet är ett fordon försett med larvband. En bomhållare 21 är anordnad på bäraren 1 och svängbar medelst cylindem 22. En borrbom 2 är fäst vid bomhållaren 21. Borrbommen 2 manövreras medelst cylindrar 23, 24. Vid borrbommens 2 främre ände är en matarbalk 3 anordnad. Matarbalken 3 är svängbar i förhållande borrbommen 2 medelst en cylinder 25. Längs matarbalken 3 är en bergborrmaskin 4 fram och åter rörlig. Kring matarbalken 3 och bergborrmaskinen 4 är ett ljuddämpande hölje 5 anordnat. Höljet 5 omsluteri huvudsak helt borrningsutrustningen. Undantaget är en längsgående öppning riktad mot operatörens plats i bäraren 1. Genom denna öppning som inte visas på ritningen kan operatören övervaka bonningsförloppet samt skarva borrstänger till eller lossa borrstänger från borrsträngen 8 som är ansluten till bergborrmaskinen 4. Det ljuddämpande höljet 5 innefattar ett bakre ändparti 6 som medelst strävor 26 är fäst vid matarbalken 3. Det ljuddämpande höljet 5 innefattar även ett främre ändparti 7 som också är fäst vid matarbalken 3 samt, i det visade exemplet, en ram 27 som medelst strävor 28 är fäst vid matarbalken 3. Det främre ändpartit 7 är försett med en manschett 11 för anliggning mot underlaget 12 i vilket bomiing skall ske. Borrsträngen 8 kan föras ut genom det främre ändpartit 7 för borrning i underlaget 12. Medel 9 i form av linor förbinder det främre ändpartit 7 med det bakre ändpartit 6. I det visade exemplet är linoma även fästa i ramen 27.. En flexibel duk 10 är medelst ögleskruv 29 förbunden med linoma 9. Duken är dessutom fäst vid det främre ändpartit 7, det bakre ändpartit 6 samt ramen 27. Härigenom kan duken delas upp i sektioner så att enkel åtkomst för service kan erhållas såsom visat i fi g 2. Duksektionema är dessutom förbundna medelst skruv och mutter 30. Den flexibla duken 10 skall lämpligen väga minst 4 kg/mz för att erhålla lämplig ljuddämpning. Som framgår av fig 4-6 kan duken 10 förses med ett lätt skikt 31 av ljuddämpamde material. another 517 918 §: = 2 :: = '-.-' 11 ”The 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 provided with caterpillar tracks. A boom holder 21 is arranged on the carrier 1 and pivotable by means of the cylinder 22. A drill boom 2 is attached to the boom holder 21. The drill boom 2 is operated by means of cylinders 23, 24. At the front end of the drill boom 2 a feed beam 3 is arranged. The feed beam 3 is pivotable in relation to the drill boom 2 by means of a cylinder 25. Along the feed beam 3, a rock drilling machine 4 is reciprocable. A sound-absorbing housing 5 is arranged around the feed beam 3 and the rock drilling machine 4. The housing 5 completely encloses the drilling equipment. The exception is a longitudinal opening directed towards the operator's place in the carrier 1. Through this opening not shown in the drawing, the operator can monitor the housing process and splice drill rods to or loosen drill rods from the drill string 8 connected to the rock drill 4. The sound-absorbing housing 5 comprises a rear end portion 6 which is attached to the feed beam 3 by means of struts 26. The sound-absorbing housing 5 also comprises a front end portion 7 which is also attached to the feed beam 3 and, in the example shown, a frame 27 which is attached to the feed beam 3 by means of struts 28. the end portion 7 is provided with a cuff 11 for abutment against the base 12 in which booming is to take place. The drill string 8 can be extended through the front end portion 7 for drilling in the substrate 12. Means 9 in the form of ropes connect the front end portion 7 to the rear end portion 6. In the example shown, the ropes are also attached to the frame 27. A flexible cloth 10 is connected by means of a loop screw 29 to the ropes 9. The cloth is also attached to the front end portion 7, the rear end portion 6 and the frame 27. Hereby the cloth can be divided into sections so that easy access for service can be obtained as shown in fig. are additionally connected by means of screw and nut 30. The visible fabric 10 should suitably weigh at least 4 kg / m 2 in order to obtain suitable sound attenuation. As can be seen from Figs. 4-6, the fabric 10 can be provided with a light layer 31 of sound-absorbing materials.

Den flexibla duken 10 kan även bestå av flera intill varandra anordnade dukar med eller utan mellanliggande skikt av ljuddämpande material. Höljet 5 kan även vara utformat med dukar utan ljuddämpande material när kravet på ljuddämpning inte är fullt så högt. Som framgår av ñ g 2 kan man lossa linoma 9 och vika undan duken 10 så att det inre av höljet 5 blir åtkomligt för service.The visible cloth 10 may also consist of adjacent cloths with or without intermediate layers of sound-absorbing material. The housing 5 can also be designed with cloths without sound-absorbing material when the requirement for sound-absorbing is not quite as high. As can be seen from ñ g 2, the ropes 9 can be loosened and the cloth 10 folded away so that the interior of the casing 5 becomes accessible for service.
