Abstract

Coupling sleeve for connecting a threaded anchor bolt (1) to an impact rock drill (2) comprising a first part (3) provided with an internal thread (4) for connecting the anchor bolt (1) and a second part (5) provided with an internal thread (6) for the connection of the rock drill (2), characterized in that the second part (5) comprises a locking device (7) arranged transversely to a longitudinal axis (9) in the coupling sleeve cooperating with a region (8) in the rock drill (2) to prevent the coupling sleeve and the rock drill (2) from separating.

Description

Coupling sleeve to connect a bolt threaded anchor to a rock drill by impacts.

The present invention relates to a sleeve coupling for connecting a threaded anchor bolt for a rock drill by impacts. More specifically the invention refers to a specific sleeve design of coupling that ensures that a certain of the two connections threaded coupling sleeve is released first when the Rock drill is disconnected from the anchor bolt.

In a previously known solution for ensure that a certain threaded connection is released first, see SE 433 097, threads with different steps are used to achieve a threaded connection that is substantially more difficult Let go of the other. These solutions have the disadvantage of that non-standard parts should be used. It must be controlled constantly which end is which to get a connection correct.

In an attempt to solve the problem previously mentioned, see WO 02/057591, a sleeve is held on the thread so it should be difficult to release. turned out that this solution has the disadvantage that it cannot assume the loads of the shock waves to which the connection is subjected threaded during drilling.

The present invention, which is defined in the subsequent claim, they have the objective of obviating the drawbacks mentioned above providing the sleeve of coupling with a locking device that cooperates with a region in the rock drill shank adapter for prevent the coupling sleeve and rock drill from separate when the rock drill and anchor bolt are separate

An embodiment of the Invention below with reference to the attached drawing where Fig. 1 shows a perspective view of a coupling sleeve according to the invention and a rod adapter and an anchor bolt for cooperation with the coupling sleeve. Fig. 2 shows a section through the device according to Fig. 1 with the anchor bolt and rock drill connected to the sleeve of coupling.

The coupling sleeve shown in the drawing comprises a first part 3 provided with an internal thread 4 to which a threaded anchor bolt 1 can be connected. The threaded anchor bolt is provided with a auger not shown to drill the hole where the anchor bolt should be anchored. The coupling sleeve also comprises a second part 5 provided with an internal thread 6 to which it can be connected a rock drill 2. The drawing shows the adapter of the stem belonging to the rock drill. The sleeve of coupling has a longitudinal axis 9. The sleeve of coupling is provided in its second part 5 with two holes 10 arranged transversely to axis 9 where a locking device 7 in the form of two spring pins. He locking device 7 cooperates with a region 8 to prevent the  coupling sleeve and rock drill 2 se separate

When an anchor bolt 1 is adjusted the rock drill stem 2 adapter rotates custom which is subjected to impacts. Through this a drill is drilled with anchor bolt 1, a hole in which the anchor bolt During drilling, the locking device 7. After drilling the bolt anchor 1 must be separated from the coupling sleeve and left on the rock By this means the rock drill rotates to Release the threaded connection. Thanks to the cooperation between the locking device 7 and region 8 having a diameter more small than the thread of the stem adapter prevents the Rock drill 2 and coupling sleeve separate. After this the drill is filled around the bolt of anchor with cement or resin for anchoring anchor bolt in the drill.
