摘要： A retaining system (100) for a DTH hammer drill bit (25) having an outer surface with a plurality of stops (31) at an up-hole end (29) of the drill bit (25) the stops projecting radially outward from the outer surface and spaced by respective gaps (35). The retaining system has a ring (102) which is configured to pass over the stops (31) when in a first rotational position relative to the drill bit (25). However when the ring (102) is in a second rotational position relative to the drill bit (25) it prohibits passage of the stops (31) through the ring (102).

摘要： Method for connecting a casing tube (4) to a drill bit (1) in which method an annular groove (6) that circulates around the outer track is formed at the outer track of the bit (1) and in order to connect the casing tube (4) to the bit (1 ) at its front edge, one uses a drill shoe, such as a connection ring (2), as an aid which drill shoe can be installed around the bit (1) and which connection ring is attached both to the mentioned annular groove (6) and on the other hand to the mentioned casing tube (4) in which case at the first stage of the installation a chopped ring element (3) is installed into the groove (6) located at the outer track of the bit (1) at least partly. At the second stage the connection ring (2) is pushed around the bit (1) so far that the ring element (3) existing in the groove (6) becomes strained at the same time into the groove (5) existing at the inner surface of the connection ring (2) in which case when the connection ring (2) is being moved, the ring element (3) follows in the groove (5) along the connection ring and slides in the groove (6) of the bit ( 1 ) in such a way that its movement to the deepest point of the groove (6) is prohibited by adding a stopper (7), (8) to the structure which stopper restricts the movement of the connection ring (2).

摘要： The invention relates to a joint arrangement for coupling of a drill shoe, the drill shoe being meant to be used when drilling a hole into the ground with a protective tube by means of a drilling device (1) that has a casing part (2) acting as the protective tube and a drilling unit (3), in a drilling head of which there are at least first drilling means (4), such as a pilot, for drilling a center hole and second drilling means (5), such as a reamer, for forming of an actual drilling hole for the casing part (2) by reaming the center hole, and whereby the casing part (2) is arranged to be pulled into the hole to be drilled by means of a joint arrangement (L), comprising a drill shoe (X) to be attached to the casing part (2) preferably by welding (h1) and being coupled with the drilling unit (3) by coupling means that enable rotative motion of the drilling unit (3) with respect to the drill shoe and that transmit power in a longitudinal direction (s). The joint arrangement comprises a drill shoe (X; Xii) that is to be coupled with respect to the second drilling means (5) essentially internally therewith. Furthermore the drill shoe pulls the casing part (2) into the hole by a power influence (F) transmitted to the drill shoe from the second drilling means (5).

摘要： A down-hole hammer comprising a drill bit (10) and a drive sub (11) with an interconnection therebetween for causing rotation of the drill bit upon rotation of the drill sub. The drill bit (10) comprises a drill bit head (13) and a shank (19), the drill bit head (13) defining a cutting face (15) and having a circumferential shoulder section (17) adjacent the cutting face (15). The shank (19) extends from the shoulder section (17) in the direction away from the cutting face (15). The interconnection between the drill bit (10) and the drive sub (11) comprises a spline assembly including at least one spline (43) on the shoulder section (17) for mating engagement with at least one counterpart spline (63) on the drive sub (11) to provide a drive coupling therebetween while also allowing the drill bit (10) to slide axially within the drive sub (11) to perform a percussive action.

摘要： The invention provides a drill bit for a down-the-hole drill hammer. The bit has a head (2) at its forward end with a shank (3) extending from the head. The shank is screw threaded along its length. A reciprocating chuck (4) is provided as a sleeve with internal screw threads corresponding to those of the shank. The shank is releasably secured in the chuck with the rear end of the shank providing a striking face. An arrangement of external splines (8) on the chuck, and a retaining shoulder at its rear end, provide for the required guided movement of the chuck within a drill hammer wear sleeve. The bit is simple to machine with screw threads replacing the usual splines and other structural features ordinarily required on this component. These features are instead provided on the chuck and in the wear sleeve.
