Definitions

  • the invention relates to a coupling for a linkage with power transmission, in particular for diamond core bits with a shaft tube and pipe thread connection.
  • diamond core bits are known. In principle, they consist of a tube with diamonds, hard metals or the like fastened in a crown-like manner on one end face. They are used in particular for drilling in rock and concrete. Depending on the application, they are operated in the wet or dry process. In both operating modes, a drill core is formed inside the tube or shaft, which can usually only be removed with difficulty. In the case of wet processes, the drill core can lead to the blocking of the coolant passed through the shaft and, in the worst case, to the destruction of the drill bit. This can occur, for example, if the drill core contains chipboard parts or foam in addition to concrete or the like.
  • Drills for diamond core bits are equipped with a threaded connection that is the same for many drilling approaches.
  • pipe thread connections of the same type adapted to the connection of the drilling machine are therefore also provided. This means that the shaft tubes provided with the drill bit on one end side are closed off on the other end side by the pipe thread connection. This means that a separate connection is required for each shaft tube. Although this connection is dimensioned for the passage of the coolant, it makes the removal of the drill core extremely difficult.
  • a diamond drill bit with a shaft tube and pipe thread connection is also known, in which each shaft tube is closed by an extension which forms a first coupling part for connection to a corresponding second coupling part of the pipe thread connection part (DE-GM 85 13 328).
  • This approach simplifies the removal of the core and makes handling the equipment easier.
  • the coupling parts can loosen or jam automatically as a result of the rotation in practical operation. In one case, the replacement is made difficult, in the other case, undesirable own movements occur during drilling.
  • the invention has for its object to provide an arrangement which enables easy coupling and uncoupling of the parts to be coupled and which does not undesirably affect the drilling process.
  • a diamond core bit 1 is shown with a shaft tube 2 and a pipe thread connection 3 in a perspective view.
  • the shaft tube 2 is provided on its one end face 4 in a crown-like manner with diamonds 5.
  • These diamonds 5 can be used as pieces and soldered or can be provided as an admixture to a hardening filling compound forming the end face of the shaft tube.
  • the end face can be provided with incisions for the passage of water.
  • the shaft tube can also be provided with openings 7.
  • the shaft tube 2 is provided with a shoulder 8, which forms a first coupling part. This approach is designed so that it allows the liquid to pass through the shaft tube 2.
  • a surface 9 is provided which is arranged essentially perpendicular to the axis of the shaft tube 2.
  • Grooves 12 are arranged diametrically opposite one another in the essentially cylindrical wall of the extension 8.
  • the pipe thread connection 3 is also provided with a substantially cylindrical extension part 35, which serves as a second coupling part. From this part 35, two projections 11, for example bolts, protrude perpendicularly to the axial direction of the shaft tube. These projections 11 act together with the grooves 12.
  • the cylindrical part 35 has an outer diameter and the extension 8 such that the part 35 can be pushed into the extension 8.
  • the grooves 12 and the projections 11 are dimensioned such that the projections can engage in and be guided by the grooves 12.
  • the outer wall of the part 35 and the inner wall are sealed off from one another, for example by an o-ring 16 in an annular groove 17 This way the connection of Shaft tube 2 and pipe thread connection 3 sealed against the leakage of the coolant.
  • the shaft tube 2 and the tube thread connection 3 practically form a first and a second coupling part, both of which can be easily coupled by the projections 11 and the grooves 12.
  • the coupling 2, 3 is such that the two parts 2, 3 are sealed at the same time by the seal 16 arranged between them when they are connected.
  • the grooves 12 in part 8 have an input part 12a which initially runs approximately in the axial direction of the shaft tube 2 and then subsequently a guide part 12b which runs obliquely or perpendicularly to the axial direction.
  • the direction of part 12b is selected so that the groove wall leads the projection 11 in the direction of a catch R when the parts 2, 3 to be coupled rotate.
  • the catch R prevents the two parts 2, 3 thus assembled from being able to come loose again without the parts rotating again. If, for example, the pipe thread connection 3 is suspended in a fixed position, the shaft pipe 2, which is often very heavy, can be raised to the coupling and loosely hung in the coupling 3. In the same way, the loosely released coupling parts cannot fall apart, but are particularly lifted out of the connection and lowered.
  • the extension 8 and the part 35 are first inserted into one another such that the protrusion (s) 11 engage in the groove parts 12a.
  • a clamping ring 25 is displaceable on the pipe thread connection part 3 such that he pulls the projection 11 firmly into the catch R.
  • part 3 is provided with an external thread and ring 25 with an internal thread.
  • the mutually facing surfaces 9 of the neck 8 and 14 of the clamping ring 25 are arranged and dimensioned such that they are pressed firmly against one another and seal their connection.
  • Fig. 2 the sectional side view of a shaft tube 2 is shown with the welded in at one end 8 and the coupled pipe thread connector 3. The seal 16 between the attachment 8 and the attachment part 35 is clearly visible.
  • a surface 22 is provided on the pipe thread attachment 3 for the application of spanners or the like.
  • Fig. 3 shows the sectional side view of an intermediate connector as a coupling piece between a rod part, e.g. an extension part 39 for the shaft tube 2, and the pipe thread connection 3 or another tube part with a corresponding threaded bolt.
  • a rod part e.g. an extension part 39 for the shaft tube 2
  • the pipe thread connection 3 or another tube part with a corresponding threaded bolt.
  • the pipe thread connection part 3 shown in the upper part of FIG. 3 is a pipe part with an internal thread for receiving the correspondingly dimensioned pipe thread 6a of the thread connection 18 of the drilling device 19.
  • the upper end of the pipe thread connection part 3 is designed as a hexagon 31.
  • the lower part 35 of part 3 has such an outer diameter that it can just be pushed easily, but without play, into the projection 8.
  • the part 35 is provided with a groove 17 for the 0-rings 16 not inserted in FIG. 3.
  • the wall of the part 35 is dimensioned so thick that the projections or bolts 11 penetrate the part 35 and can protrude on each side sufficiently to be able to engage in the grooves 12 of the extension 8 without the strength of the part 35 being impermissibly small Assumes values.
  • the bolts 11 close with the outside of the extension 8 and are rounded off so that they cannot have a disruptive effect on the drilling operation.
  • the inner, clear width of the part 35 is dimensioned so that despite the penetrating bolt parts 11 sufficient liquid passage is ensured.
  • the lower end of the extension 8 is provided with a tubular threaded bolt 81, which is formed in FIG. 3 as a prefabricated part with a hexagon 82 and is welded to the extension 8.
  • the threaded bolt 81 is screwed into the extension tube 39 or the like provided with a corresponding thread, and thus enables the simple connection of drill pipes.
  • a further seal is provided by the clamping ring 25, which can be rotated with its internal thread 32 on the external thread 33 of the pipe thread connection part 3 and presses with its end face 14 against the end face 9 of the attachment 8. During this rotation, the part 35 inserted and twisted into the extension 8 is first lifted back out of the extension 8 until the projections 11 in the catch R ver are clamped and the parts 3 and 8 are positively and non-positively connected. By appropriate design of the abutting surfaces 9, 14, this connection is sealed at the same time. It has been shown that these parts 3, 8 can work trouble-free even if the clamping ring 25 should loosen.
  • the projections 11 are sufficient as a drive connection, the tolerances of the parts 8 and 35 prevent these parts from tilting, and the 0-ring 16 in connection with the narrow gap between the parts 8, 35 is sufficient as a seal.
  • the coupling according to FIG. 3 therefore enables an almost problem-free drilling operation with easy interchangeability.
  • Pipe thread connection 3 and neck 3 are designed as a unit coupling for drill pipes 39 and shaft pipes 2 of different diameters and lengths.
  • the pipe thread connection part 3 is essentially provided as a coupling component which can be used directly for the connection of all pipes provided with lugs 8, while the lug 8 as a unit coupling part is previously firmly connected by welding or screwing to the pipes 2.35 of different dimensions.
  • a flange 10 is provided for this connection of the extension 8 with a shaft tube 2, which flange 8 can consist of one piece or is welded to the extension 8.
  • FIG. 5 shows an assembly similar to FIG. 4, but with an extension 8 screwed into the shaft tube.
  • All Shaft tubes 2, which are permanently connected to such a unit 8 to form a unit for the operating case, for example welded or screwed, can be exchangeably connected to a unit with a correspondingly adapted tube thread attachment 3.
  • Each drill equipped with a uniform attachment 3 can be equipped with a large number of shaft tubes 2 quickly and easily.
  • the drill core can be removed while the next diamond drill shaft 2 is already installed and in use.
  • the shaft tubes 2 can have a relatively long length in order to penetrate thick concrete ceilings or the like in concrete drilling machines. For this purpose, they can also be supplemented with extension tubes.
  • the shaft tubes 2 can also be made relatively short if they are used, for example, for drilling out socket holes.
  • the clamping ring can also have surfaces 13, 15 which are inclined and match one another in addition to the surface 14 and the extension 8 in addition to the surface 9.
  • the opposite surfaces 13, 15 can essentially serve to center the parts 2, 3 during assembly if the parts to be connected are unwieldy.
  • Precision stems according to DIN 2391 have proven themselves as shaft tubes 2.
  • other seamless steel tubes that meet the respective requirements can also be used.
  • a smooth wall was tested as the inner wall for the shaft tube 2.
  • a problem-free removal of the drill core also results with an inner wall that has longitudinal grooves. Such an inner wall would have the additional advantage that the Core can not or only rarely block the water flow.
  • a shaft tube with an inner wall like a drawn barrel for rifles or guns also meets the requirements for water flow and easy removal of the drill core.
  • Fig. 6 shows an approach 8 with a flange 10 as a structural unit for the connection with drill pipes, in particular shaft pipes 2 of larger diameter.
  • the flanges are provided with holes for the screw connection of the flange 10 with the appropriately designed end of the tube.
  • Fig. 7 an approach 8 is shown, which is connected to a threaded bolt 20 to form a unit or is made in one piece therewith.
  • This approach is primarily intended for but not limited to drill pipes or small diameter shaft pipes.
