Abstract
The invention relates to a method and a device for releasing a block on a bore-crown (1) during a boring process, especially percussion boring or rotary percussion boring, for boring holes in the ground or rock, whereby a borehole is formed by a bore-crown (1) mounted on a boring rod (2) and connected thereto and acted upon by the boring rod to generate a rotational movement and optionally a percussive movement. According to the invention, when the bore-crown (1) is blocked, preventing the continuation of the boring process and especially another rotational movement of the bore-crown (1), the bore-crown (1) is subjected to a linear movement in the opposite direction to the boring direction by means of the boring rod (2), and to a rotational movement in a direction opposing the direction of the rotational displacement during the boring process by means of a corresponding connection (7, 9) between the end of the boring rod (2) facing the bore-crown (1), and the bore-crown (1), independently of a rotary drive for carrying out the boring process. As a result the borehole can be bored in a simple manner after releasing the block on the bore-crown (1).
Claims (12)
1. A method for releasing a blockage of a drill bit (1) during the drilling, particularly percussion or rotary percussion drilling, of holes in soil or rock material, wherein a borehole is formed by a drill bit (1) mounted on a drill rod assembly (2) and connected thereto and acted upon by the drill rod assembly (2) to perform a rotational movement and optionally a percussive movement, characterized in that, at a blockage of the drill bit (1) preventing the continuation of a drilling procedure and, in particular, any further rotational movement of the drill bit (1), the drill bit (1), via the drill rod assembly (2), is subjected to a linear movement opposite the drilling direction and, in addition, a rotational movement in a direction opposite the direction of the rotational movement during the drilling procedure via an appropriate connection (7, 9) between the end of the drill rod assembly (2) facing the drill bit (1) and the drill bit (1) and independently of a rotary drive for carrying out the drilling procedure.
2. A method according to claim 1, characterized in that the connection between the end of the drill rod assembly (2) facing the drill bit (1) and the drill bit (1) is realized via an adapter (3) comprising at least one helicoidal or spiral-shaped depression or flattening (19) or elevation (7), and a complementary profiling (9) provided on the drill bit (1), said helicoidal or spiral-shaped depression or flattening (19) or elevation (7) comprising a large inclination or pitch relative to the longitudinal axis of the drill rod assembly (2).
3. A method according to claim 2, characterized in that a plurality of helicoidal or spiral-shaped profilings (7, 9, 19) are provided, which are uniformly arranged about the periphery of the end facing the drill bit (1).
4. A method according to claim 1, 2 or 3, characterized in that a merely pointwise engagement on several sites in the region of the profilings (7, 9, 19) between the drill rod assembly (2) or adapter (3) and the drill bit (1) is provided.
5. A device for releasing a blockage of a drill bit (1) during the drilling, particularly percussion or rotary percussion drilling, of holes in soil or rock material, wherein a drill bit (1) is mounted on a drill rod assembly (2) and acted upon by the drill rod assembly (2) to perform a rotational movement and optionally a percussive movement for the formation of a borehole, characterized in that at least one spiral-shaped or helicoidal connection (7) is provided between the end of the drill rod assembly (2) facing the drill bit (1) and the drill bit (1), which, at a blockage of the drill bit (1) upon retraction of the drill rod assembly (2) opposite the drilling direction, in addition to a linear movement opposite the drilling direction, acts upon the drill bit (1) to perform a rotational movement in a direction opposite the direction of rotation during the drilling procedure independently of a rotary drive for carrying out the drilling procedure.
6. A device according to claim 5, characterized in that the at least one spiral-shaped or helicoidal connection is comprised of a depression or elevation (7) or flattening (19) provided on an adapter (3) arranged between the drill rod assembly (2) and the drill bit (1), and a complementary profiling (9) provided on the drill bit (1).
7. A device according to claim 5 or 6, characterized in that a plurality of helicoidal or spiral-shaped profilings (7, 9, 19) are provided between the drill rod assembly (2) or adapter (3), respectively, and the drill bit (1), which are each equidistantly arranged.
8. A device according to claim 5, 6 or 7, characterized in that the at least one helicoidal or spiral-shaped connection or profiling (7, 19) comprises a large pitch or inclination relative to the longitudinal axis of the drill rod assembly.
9. A device according to any one of claims 5 to 8, characterized in that a plurality of substantially point-shaped or semispherical elevations (9) are provided in a pocket hole (11) of the drill bit (1) for cooperation with the spiral-shaped or helicoidal depression(s) or recess(es) (7) on the end (6) of the adapter (3) facing the drill bit.
10. A device according to any one of claims 5 to 8, characterized in that a plurality of adjacent, spiral-shaped flattenings (19) are provided on the outer periphery of the adapter (3) or drill rod assembly (2), respectively, and complementary flattenings are provided in a pocket hole (11) of the drill bit (1), said flattenings having polygonal, for instance hexagonal, contours in terms of cross section.
11. A device according to any one of claims 5 to 10, characterized in that, in the interior of the drill rod assembly (2) and/or the adapter (3), a passage channel (12, 13) for supplying a cooling or flushing fluid to the outlet channels or holes (14, 16) of the drill bit (1) and/or the adapter (3) is provided, which discharge on the working face (15) of the drill bit (1) and/or the peripheral surface of the adapter (3).
12. A device according to any one of claims 5 to 11, characterized in that, in a manner known per se, depressions or recesses (18) and/or passage openings (17) are provided on the outer periphery of the drill bit (1) for removing excavated material through an annular space between the outer periphery of the drill rod assembly (2) and the inner wall of the produced borehole.
