| 101 | Mechanical directional drilling jar | EP87107591.7 | 1987-05-25 | EP0248316A2 | 1987-12-09 | Teng, Chuan C.; Blacklaws, John E.; Chapelle, Rene A.; McComsey, Lee E. |
A drilling jar (100) includes a swivel (20) which allows the drilling jar to operate substantially independently of any right hand torque that becomes trapped in the drill string. The swivel (20) includes a bearing cage (9) that engages the polished stem (4) of the drilling jar to the jay stem (5) of the drilling jar. This bearing cage (9) holds a number of bearings (10) against the jay stem (5) and the polished stem (4). The swivel (20) allows the jay stem (5) to rotate substantially independently of the polished stem (4). The drilling jar may further include splines (8) formed onto the outer surface of the polished stem (4) for transmitting torque from the polished stem (4) to the barrel (1) of the drilling jar without simultaneously transmitting torque from the polished stem (4) to the jay stem (5). In addition, the drilling jar may include floating pistons (11,12) that are circumferentially engaged to the polished stem (4) and the washpipe (7) that effect the upper and lower seals on the drilling jar and allow the internal pressure inside the tool to be equalized with the internal and external pressures of the drill string. |

An attachment for a percussive rock drilling machine (12) of the kind being displaceable along a feed beam (14) by a feeding motor. The attachment (15) is arranged for enabling withdrawal of drill steels (16) which are stuck in the drilled hole. The attachment (15) comprises a spring housing (17) which contains a compressive spring (22) and a stopping member (23), said housing being suspended by flexible means (26. 27) from a yoke-shaped member (18) coupled on to the drilling machine body (19). The stopping member (23) is arranged to abut against a coupling sleeve (32) or the like on the drill steel (16). When retracting the drilling machine (12) by said feeding motor and starting the ordinary percussive action the impacts directed downwards will be transformed to impacts directed upwards which loosen and withdraw the stuck drill steel (16). |
