Abstract

A rock drilling rig comprising a first boom member (12) connected to a carrier (11) by a universal joint (13) and a second boom member (14) being longitudinally displaceable relative to the first boom member by a hydraulic cylinder (18) inside the second boom member. The external surface of the hydraulic cylinder is provided with lands (25) and intervening grooves (26) into which ridges (27) on second boom member (14) extend. A rotary motor (17) at the rear end of first boom member (12) rotates the second boom member by rotating the hydraulic cylinder. <IMAGE>

Description

500 903 2 långsträckt bomdel 12 är monterad medelst en universalled 13. Den första bomdelen är svängbar relativt bäraren medelst två hydraulcylindrar 32, endast en synlig på ritningen. 500 903 2 elongate boom part 12 is mounted by means of a universal joint 13. The first boom part is pivotable relative to the carrier by means of two hydraulic cylinders 32, only one visible in the drawing.

En andra långsträckt bomdel 14 styrs av den första bomdelen fór längsgående rörelse i denna. Ett glidlager 28 är placerat mellan de första och andra bomdelarna. Vid den bakre änden på första bomdelen 12 är en rotationsmotor 17 monterad. Rotationsmotorns utgående axel 19 är medelst en splineskoppling 29 förbunden med en hydraulcylinder 18 som kan roteras medelst rotationsmotom 17. Hydraulcylinderns ytteryta är försedd med ett antal längsgående kammar 25 och mellanliggande spår 26. Den andra bomdelen 14 år vid den bakre ände av sin inre yta försedd med kammar 27 som sträcker sig in i spåren 26 på hydraulcylindern 18. På detta sätt överförs hydraulcylindems 18 vridning till den andra bomdelen 14 oberoende av den andra bomdelens läge längs hydraulcylindem. Ett plastark 30 är placerat över kammarna 27 för att bilda ett lager mellan hydraulcylindern 18 och den andra bomdelen 14. En kolv 31 med en kolvstång 20, som har en längdaxel 21, är rörliga längs hydraulcylindem 18 medelst hydraulfiuidum tillfört till hydraulcylindem på endera sidan av kolven 31. Kolvstången 20 är förbunden med den andra bomdelen 14 så att fórflyttning av kolven 31 medför relativ längsrörelse mellan de första och andra bomdelarna 12,14.A second elongate boom member 14 is guided by the first boom member for longitudinal movement in this. A plain bearing 28 is located between the first and second boom members. At the rear the end of the first boom part 12 is a rotary motor 17 mounted. Rotary motors output shaft 19 is connected by means of a spline coupling 29 to a hydraulic cylinder 18 which can be rotated by means of the rotary motor 17. The outer surface of the hydraulic cylinder is provided with a number of longitudinal ridges 25 and intermediate grooves 26. The second boom part 14 years at the rear end of its inner surface provided with cams 27 extending into the grooves 26 on the hydraulic cylinder 18. In this way, the rotation of the hydraulic cylinder 18 is transmitted to the other boom part 14 regardless of the position of the other boom part along the hydraulic cylinder. A plastic sheet 30 is placed over the cams 27 to form a bearing between the hydraulic cylinder 18 and the second boom part 14. A piston 31 with a piston rod 20, which has a longitudinal axis 21, is movable along the hydraulic cylinder 18 by means of hydraulic till uidum supplied to the hydraulic cylinder on either side of the piston 31. The piston rod 20 is connected to the second boom part 14 so that movement of the piston 31 results in relative longitudinal movement between the first and second boom parts 12,14.

Vid den främre änden på den andra bomdelen 14 är ett bomhuvud innefattande en vridmotor 22 monterad. Denna vridmotor gör det möjligt att vrida bomhuvudet kring dess axel 23 utöver de rörelser som möjliggörs av den andra bomdelen. En hållare 33 för matarbalken 15 är svängbar kring en tapp 34 medelst en hydraulcylinder 35. Matarbalken 15 är förskjutbar i hållaren 33 medelst hydraulcylindern 36. En bergborrningsmaskin 16 är rörlig längs matarbalken 15 på sedvanligt sätt.At the front end of the second boom portion 14 is a boom head comprising one rotary motor 22 mounted. This rotary motor makes it possible to rotate the boom head around it shaft 23 in addition to the movements made possible by the second boom part. A holder 33 for the feed beam 15 is pivotable about a pin 34 by means of a hydraulic cylinder 35. The feed beam 15 is displaceable in the holder 33 by means of the hydraulic cylinder 36. A rock drilling machine 16 is movable along the feed beam 15 in the usual manner.
