Abstract

Coupling sleeve for connection of a threaded rock bolt (1) to an impact rock drilling machine (2), the coupling sleeve comprises a first part (3) provided with an internal thread (4) for connection of the rock bolt (1) and a second part (5) provided with an internal thread (6) for connection of the rock drilling machine (2). The second part (5) comprises a longitudinal slot (7) and clamping means (8) for squeezing the slot (7) through which the second part (5) is clamped about the rock drilling machine (2).

Description

:xtnv |»>|| Aiooibaadoc 5 1 6 9 9 5 fastspänning av det andra partit 5 kring bergborrmaskinen 2 inte blir störande för funktionen. Kopplingshylsan är även försedd med en fläns 10 mot vilken bergbulten 1 och bergborrmaskinens 2 nackadapter anligger. Bergborrmaskinens slagenergi överförs via flänsen 10 till bergbulten 1 då denna borras in i det underlag i vilket bergbulten skall förankras. Medelst den visade konstruktionen säkerställs att gängförbandet mellan bergbulten 1 och gängan 4 är det förband som lossas då kopplingen mellan bergborrmaslcinen och bergbulten bryts. : xtnv | »> || Aiooibaadoc 5 1 6 9 9 5 clamping of the second part 5 around the rock drilling machine 2 does not interfere with the function. The coupling sleeve is also provided with a shaft 10 against which the rock bolt 1 and the rock drill 2's neck adapter abut. The impact energy of the rock drilling machine is transmitted via the flange 10 to the rock bolt 1 when it is drilled into the substrate in which the rock bolt is to be anchored. By means of the construction shown, it is ensured that the threaded connection between the rock bolt 1 and the thread 4 is the connection that is loosened when the coupling between the rock drilling machine and the rock bolt is broken.
